I've got a similar setup; and with both wi/an driver's have not seen this (the IPaq uses a lucent, linksys or D-Link card). The only panic's I hever had where on early AP mode running wi's - which has been fixed for sure in -CURRENT and 4.5-RC2. Could you show a backtrace and/or list in detail the set up (cards, kernel versions, etc).

It takes a while for the box to realize the card has been ejected, ~2-10 minutes. if I startup the ipaq and bring up the wireless card -before- the fbsd box everything is fine. as for the panic, the box rebooted awfully quick, maybe coulda been anything no kernel gdb sorry. and I have not been able to reproduce it as of yet.

Sounds OK to me, although I worry a little bit about relying on the zeroing of the memory by mmap. I don't see it documented in the man page, so there's a (slight) risk that somebody could remove that feature in the future.

Your search_ip() function is a linear list traversal, which makes a lookup O(N). Is there any change you could use a hash or a btree or a skiplist or a trie or some other data structure *other* than a linear list traversal? It seems to me that this will make things incredibly slow for everyone, if you have one IP address that's abusive enough that it approaches the limit you set. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Sun Jun 16 20: 7: 7 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from avocet.mail.pas.earthlink.net (avocet.mail.pas.earthlink.net [207.217.120.50]) by hub.freebsd.org (Postfix) with ESMTP id 0C87B37B40B for ; Sun, 16 Jun 2002 20:07:04 -0700 (PDT) Received: from pool0036.cvx21-bradley.dialup.earthlink.net ([209.179.192.36] helo=mindspring.com) by avocet.mail.pas.earthlink.net with esmtp (Exim 3.33 #2) id 17Jmr7-0005ti-00; Sun, 16 Jun 2002 20:07:01 -0700 Message-ID: <3D0D522D.F30747A4@mindspring.com> Date: Sun, 16 Jun 2002 20:06:21 -0700 From: Terry Lambert X-Mailer: Mozilla 4.7 [en]C-CCK-MCD {Sony} (Win98; U) X-Accept-Language: en MIME-Version: 1.0 To: eirikn@bluezone.no Cc: freebsd-hackers@freebsd.org Subject: Re: Kernel hacking References: <20020616161710.A339@eirikn.net> Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG Eirik Nygaard wrote: > I want to start recodeing the FreeBSD kernel, just for fun.

I can't make something usefull yet, but I want to learn. The word "recoding" implies that you want to rewrite the code from scratch. If you wanted to do something else, then you need to pick it; otherwise we can all probably mail-bomb you with thousands of suggestions, based on 20/20 hindsight. We all know what we would do different, if we had it all to do over again. If you just want to learn about some part, then you need to pick the part you want to learn about first, look at the code, and ask questions about what you don't understand, when you run into it. If you already know some other system pretty well, then the easiest thing to do is to take some code you know, and port it to FreeBSD, or, if that's too complicated, then compare it with code already in FreeBSD. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Mon Jun 17 2:47:28 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from gate.nentec.de (gate2.nentec.de [194.25.215.66]) by hub.freebsd.org (Postfix) with ESMTP id D580837B400 for ; Mon, 17 Jun 2002 02:47:20 -0700 (PDT) Received: from nenny.nentec.de (root@nenny.nentec.de [153.92.64.1]) by gate.nentec.de (8.11.3/8.9.3) with ESMTP id g5H9lJA22772 for ; Mon, 17 Jun 2002 11:47:19 +0200 Received: from nentec.de (andromeda.nentec.de [153.92.64.34]) by nenny.nentec.de (8.11.3/8.11.3/SuSE Linux 8.11.1-0.5) with ESMTP id g5H9lDZ27207 for ; Mon, 17 Jun 2002 11:47:14 +0200 Message-ID: <3D0DB021.4080102@nentec.de> Date: Mon, 17 Jun 2002 11:47:13 +0200 From: Andy Sporner User-Agent: Mozilla/5.0 (X11; U; Linux i686; de-AT; rv:0.9.8) Gecko/20020204 X-Accept-Language: de-at, de, en, en-us MIME-Version: 1.0 To: freebsd-hackers Subject: Kernel Panic using kproc_exit() on FreeBSD 5.0-20020302-PREVIEW References: <3D099F31.8F0F0702@mindspring.com> Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit X-Virus-Scanned: by AMaViS-perl11-milter (http://amavis.org/) Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG Hi Hackers, First of all... > >Knuth's books: Collect them all!

I fixed this problem by removing one of the blocks defining send_sessionid in ng_pppoe.c .. I've submitted this as a bug-report too. I'm not much of a C programmer or anything, but taking out that one blick fixed it just fine. I'm guessing the double definition is simply a cut and paste flaw or something of the sort. > regards, > le -- -Jonas To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Mon Jun 17 7:39: 6 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from harrier.mail.pas.earthlink.net (harrier.mail.pas.earthlink.net [207.217.120.12]) by hub.freebsd.org (Postfix) with ESMTP id 42A6E37B423 for ; Mon, 17 Jun 2002 07:39:03 -0700 (PDT) Received: from pool0073.cvx40-bradley.dialup.earthlink.net ([216.244.42.73] helo=mindspring.com) by harrier.mail.pas.earthlink.net with esmtp (Exim 3.33 #2) id 17Jxen-0005AP-00; Mon, 17 Jun 2002 07:39:01 -0700 Message-ID: <3D0DF45F.C616C7CA@mindspring.com> Date: Mon, 17 Jun 2002 07:38:23 -0700 From: Terry Lambert X-Mailer: Mozilla 4.7 [en]C-CCK-MCD {Sony} (Win98; U) X-Accept-Language: en MIME-Version: 1.0 To: gauthamg123list@myrealbox.com Cc: "FreeBSD.org - Hackers" Subject: Re: Inserting a kernel module b/w IP and ethernet References: Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG Gautham Ganapathy wrote: > How can I add an extra layer of processing b/w the IP and ethernet layers > using a kernel module ?

My > requirement is to add a compression layer (RFC 2507) Questions like this should probably be sent to -net, rather than -hackers. You will probably find a better answer than mine, just by searching the -net list archives at www.freebsd.org. The RFC specifically references a NetBSD implementation for PPP; is this for PPP? If it's for PPP, then mpd may have already implemented what you need as a netgraph node. One thing you aren't going to be able to do is BPF on input after netgraph catches the data. Don't bother with a protocol family, unless you want to have to implement everything; TCP in tcp_output() calls ip_output() directly, so you will not be able to wedge it in there (TCP and IP are not implemented as stackable protocol layers seperate and distinct from each other). I can point you at code that does this, but it requires changing your application in order to make it open sockets with the new family instead of AF_INET; if you ar adamant, the code is at Rice University, as part of the Scala Server Project. My particular choice for an example would be /sys/netgraph/ng_pppoe.c but others might point you to something else. Julian or Archie are always the best people to ask (obviously). You could also create an interface (see /sys/netgraph/ng_iface.c) that pretended to be a plain old interface, and did the encapsulation/deincapsulation, and sent to the regular interface. The basics are going to be that you replace the mbuf with your modified mbuf, rather than eating it outright, if you want the input/output processing to proceed normally on the (de)compressed packet. I don't know if there is a ng_null that anyone has written; it would *really* be the best starting point. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Mon Jun 17 8: 0:56 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from smtpproxy2.mitre.org (smtpproxy2.mitre.org [192.80.55.70]) by hub.freebsd.org (Postfix) with ESMTP id 49F0937B415; Mon, 17 Jun 2002 08:00:32 -0700 (PDT) Received: from avsrv2.mitre.org (avsrv2.mitre.org [128.29.154.4]) by smtpproxy2.mitre.org (8.11.3/8.11.3) with ESMTP id g5HF0Bl28594; Mon, 17 Jun 2002 11:00:11 -0400 (EDT) Received: from MAILHUB1 (mailhub1.mitre.org [129.83.20.31]) by smtpsrv2.mitre.org (8.11.3/8.11.3) with ESMTP id g5HF08O03329; Mon, 17 Jun 2002 11:00:08 -0400 (EDT) Received: from mm112324-2k.mitre.org (128.29.105.135) by mailhub1.mitre.org with SMTP id 10589530; Mon, 17 Jun 2002 10:59:28 -0400 Message-ID: <3D0DF96C.EAAFB18A@mitre.org> Date: Mon, 17 Jun 2002 10:59:56 -0400 From: Jason Andresen Organization: The MITRE Corporation X-Mailer: Mozilla 4.79 [en]C-20020130M (Windows NT 5.0; U) X-Accept-Language: en MIME-Version: 1.0 To: "Daniel C.

This brings up something I was trying to find a solution for over the weekend. I just purchased the latest Tyan dual Athlon motherboard (S2466N-4M)[0] and got FreeBSD 4.6 up and running on it. It's working flawlessly so far, which I'm quite pleased with. It's always a roll of the dice buying new hardware without verified compatibility reports. I would like to monitor the CPU temperature to keep an eye on how efficient my cooling setup is (these dual Athlons get hot). The motherboard uses a Winbond W83782D hardware monitoring chip and comes with Windows software which supports it. Does anyone know of an open source app which will read the temperature off of this thing, or have pointers to documentation so I can write my own? I have had no luck getting [x]mbmon to use it. mbmon seems to only support the Winbond 83627HF chip. Gkrellm only appears to support LM7[89] chips via lm_sensors. Something which provided an SNMP interface would be ideal, even if I have to write that wrapper myself, since I'd like to be able to graph it via mrtg or similiar. I've been googling around without much success. Any thoughts or suggestions on where to turn? [0] - http://www.tyan.com/products/html/tigermpx.html Brandon D.

Dean wrote: >lm-sensors has information on this chip. Yes, thank you. I've just been reading through the bug database at lm-sensors.nu on a recommendation from a fellow Tyan Tiger MPX owner. I now have healthd installed but am only able to grab the voltages from the hardware, not the CPU temp or fan speeds. This is evidently related to the fact that there are actually two Winbond hardware monitoring chips onboard and the functions are divided between them. According to the linux guys in order to initialize the second monitoring chip on boot you must either go into a BIOS hardware monitoring menu or temporarily boot Windows and launch the included monitoring software. The Tiger MPX BIOS does not currently contain a hardware monitoring menu because the original revision of the board only had a 2MB BIOS ROM. The newer revision I have has a 4MB BIOS ROM on it so I hope that I will be able to obtain a BIOS from Tyan which includes this functionality. I would very much like to verify this theory. I would also like to see if I can figure out a workaround to initialize this chipset without requiring a trip to the BIOS or Windows. Hopefully the Linux lm_sensors folks can help me make sense of it. Brandon D.

Let's see, some weeks ago a couple of people dropped their ports maintainership, why did this happen? Sergey dropped his ports because David O'Brien is an asshole. Yes, no news, we all know that. Asmodai resigned some days ago, why? Because fucking Bill Fumerola is a royal asshole. Has fucking Bill Fumerola ever done any worthwhile work for FreeBSD? NO. He prefers to spend his time flaming other people. FUCK YOU FUMEROLA! Jordan Hubbard left, Mike Smith left. Why? Because a large number of the people involved in FreeBSD are either assholes or hypocrites. What's the prefered game in #bsdcode? Right, flaming Terry Lambert. Terry may not be perfect, but he has *never* insulted anyone, he's a nice person to talk to, and pretty often comes up with nice ideas. I'm talking to you, fucking Hiten Pandya, damned asshole. And I'm talking to you, stupid Alfred Perlstein. Alfred is an interesting person. He seems to be drunk most of the time, has never contributed anything important to the project, yet he likes to flame around all the time. Matthew Dillon is one of the few hackers worth his salt, what does he get in return? A 5 day commit bit suspension. Matt, please, join NetBSD, they need help in the SMP code, and leave all these hypocrites alone. David O'Brien -> good hacker but a total asshole Dag-Erling Smorgrav -> a total asshole Alfred Perlstein -> drunktard and hypocrite Bill Fumerola -> The überasshole, FUCK FUMEROLA!!!! Kris Kennaway -> Hyprocrite Hiten Pandya -> an IMBECILE, grow up fucking moron You all owe Terry Lambert an apology, stupid hypocrites. To the rest of the people, jump shit now, and join NetBSD while you can.

My favorite boards for this kind of thing are laptop motherboards, since they have the connections for a built in UPS, automatic software controlled power management, and the majority of the cost is in the display, with most of the rest of it being in the micro mechanicals that you don't need in an embedded system (PCMCIA slots, keyboard, tiny floppy, docking crap, speakers, microphone, expansion bays for CDROM, etc.).

So this is what I do :- fd = open(file, O_RDWR); p = mmap(fd, MAP_NOSYNC | MAP_SHARED); mlock(p, len); /* Whack around with shmem */ Now my question is , once I have wired the shared memory region, is it possible that the data still hits the disk ? One would think the pager will not look at wired pages. Is that correct ? Thanks in advance. Joy __________________________________________________ Do You Yahoo!?

I just installed HylaFax on our FreeBSD 4.5-STABLE machine. 

Couple of small issues. 

First with regards to TGIF (in particular netpbm).

1) I created a fax cover sheet/page using the TGIF program. 
First problem with this is that the netpbm port that is required to properly install TGIF is apparently not functioning.
make runs fine, but I get the following error when I try to do a make install in /usr/ports/graphics/tgif

spxdev:root# make install
===>  Installing for tgif-4.1.41
===>   tgif-4.1.41 depends on executable: giftopnm - not found
===>    Verifying install for giftopnm in /usr/ports/graphics/netpbm
===>  Extracting for netpbm-9.24
>> Checksum mismatch for netpbm-9.24.tgz.
Make sure the Makefile and distinfo file (/usr/ports/graphics/netpbm/distinfo)
are up to date.  If you are absolutely sure you want to override this
check, type "make NO_CHECKSUM=yes [other args]".
*** Error code 1

*** Error code 1

spxdev:root#

Commenting out the

RUN_DEPENDS=    giftopnm:${PORTSDIR}/graphics/netpbm

line in Makefile allows tgif to be installed fine, with the exception that I can not import gif/jpg/png graphics.



2)  The HylaFax problem I have is that the to-company and regarding fields to not appear on my cover page.

I'm calling sendfax with the following example:

sendfax -d"name@faxnumber" -x "company name" -r "subject/regarding" filename

The fax sends fine, and uses my default cover page,
but the Company:  and Re: fields are blank as if sendfax didn't pass the variables at all.

I decided to try the default cover page (Silicon Graphics logo and all)... And noticed that the
Company and Re: fields are blank there as well.  So it would appear that there's a bug in HylaFax for FreeBSD.
I have tried this on a Linux box and it works fine. 


Just wondering if anyone else has seen this problem and has perhaps a fix for it?

Thanks in advance.

Sergey dropped his ports because David O'Brien is an asshole. Yes, no news, we all know that. Asmodai resigned some days ago, why? Because fucking Bill Fumerola is a royal asshole. Has fucking Bill Fumerola ever done any worthwhile work for FreeBSD? NO. He prefers to spend his time flaming other people. FUCK YOU FUMEROLA!

I don't understand this. Where does all this nastiness happen? Maybe it's on -core. I don't read that. But in the year or so that I've been reading -security, -stable, and -hackers, I haven't seen any nastiness. I've seen people who disagree with each other, and I've seen people get annoyed when the same issues are brought up over and over again, but I really haven't seen anything which I'd call *nasty*. Can't we all be a bit more tolerant and get along with each other?

Alas, you discredit yourself by posting >pseudonymously and by doing a great deal of flaming yourself. Perhaps you should qualify your definition of "good points". I saw no evidence behind any accusations made. I saw ad hominem attacks calling FreeBSD developers assholes and drunkards. Any points made by the author were merely begging the question. He gave no evidence that any of the attitudes of the people he mentioned were in some way detrimental to the project, he merely asserts that this must be true. He is also committing the sin of a /post hoc ergo propter hoc/ argument. The attitudes of a few developers within the FreeBSD community, if they are indeed causing a problem, may not be in any way related to the effects the poster was trying to justify cause for. Argument without substance is not argument at all. It's wasted breath and/or keystrokes. Brett, I've been reading your postings long enough to know you're an argumentative sort and also that your mien seems to be self-perpetuating because people now approach you as if to have an argument. Please understand I am not trying to argue with you. I am pointing out fallacies in someone else's opinions which I think you may have overlooked. I wish neither to defend the developers attacked by the poster nor defend the poster himself. Replies challenging me to do so will be directed to /dev/null. Brandon D.

You could cross-reference the interfaces returned by getifaddrs() with the list of PCI devices from the PCIOCGETCONF ioctl. (see pci(4)) It would only work for PCI NICs, but would be better than nothing. There are probably other ways to do it as well.

Or do not work flawlessly across hardware upgrades. I have an installation here at home that has gone through many hardware upgrades (motherboard, cpu, or other vital parts) and has worked like a charm, compiling worlds since 3.2-RELEASE from source. Having a userland or kernel that is 486-specific would have been a major PITA when I changed the cpu to a Pentium, with a new PITA waiting at the next corner, when I switched to a Celeron, etc. I feel that it's very nice that "uname -p" and "uname -m" still print "i386" in their output :-] - Giorgos To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Tue Jun 18 16:18:15 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from critter.freebsd.dk (critter.freebsd.dk [212.242.86.163]) by hub.freebsd.org (Postfix) with ESMTP id 36F0E37B406 for ; Tue, 18 Jun 2002 16:18:11 -0700 (PDT) Received: from critter.freebsd.dk (localhost [127.0.0.1]) by critter.freebsd.dk (8.12.3/8.12.2) with ESMTP id g5INGQIj035671 for ; Wed, 19 Jun 2002 01:16:26 +0200 (CEST) (envelope-from phk@critter.freebsd.dk) To: hackers@freebsd.org Subject: 8" floppy drive anyone ?

The one thing I found a bit surprising was the lack of support for multiple IP addresses in jail environments. I did some research into the issue, and I found the various posts discussing why this decision was made. While a ``true'' multiple IP address implementation (INADDR_ANY, loopback, etc.) may be rather involved, getting more than one IP address into the jailed environment might be much simpler. Here is my proposal: Rather than specifying a single IP address when constructing the jail, supply an IP address and netmask. The kernel can then use the IP address in conjunction with the netmask to determine what range of addresses are allowed in the jail without having to run through an actual list of addresses. This approach is similar to how ISPs assign CIDR blocks to their customers. It has various advantages and disadvantages over the method of providing a list of allowed addresses. I consider its primary advantage to be that it is extremely simple to implement (as can be seen by the attached diff) and does not affect jail's runtime performance. Granted, this method does not solve the INADDR_ANY and localhost issues, but any solution to that side of the jail puzzle is sure to be an invasive one. The attached diff is based on 4.6-RELEASE. To use it, build and install the jail binary and a new kernel. By default, this diff results in a jail binary that acts the same as before. Adding a ``/ne.tm.as.k'' to the jail call will allow the jail to allocate any of the IP addresses in the netmask. For example.. jail /home/jail myhost 10.20.30.8/255.255.255.248 /bin/sh ..would allow the jail to use all of the following addresses.. 10.20.30.8 10.20.30.9 10.20.30.10 10.20.30.11 10.20.30.12 10.20.30.13 10.20.30.14 10.20.30.15 INADDR_ANY and 127.0.0.1 still use the first address. I changed jail's version number (from 0 to 1) as this affects the syscall. I look forward to your comments, suggestions, criticisms, etc. Thank you for your time!

From on and off-list correspondence with folks trying to get FreeBSD running on the A7V333 (on which I'm happily running 4-STABLE), it's Soeren Schmidt's ATA driver improvements which allow FreeBSD to work with the PDC20276 controller chip.

Got rid of anything this ancient years ago, but I'd suggest checking with the local university to see if they keep surplus electronics onhand. I know that my employer here in the states. Vanderbilt University, keeps a rather large warehouse of surplused electronics equipment because it's illegal for them to dispose of it in landfills and their waste disposal contractor would cancel their contract if they did. These types of facilities are a goldmine for finding old, obscure equipment. I've heard of numerous professors scrounging complete test apparatus out of that warehouse. Brandon D.

The problem reports database (accessible over the web at http://www.freebsd.org/prstats/index.html) can always use a good looking-over. Some reports are outdated and just need to be closed; some have a working patch included but have fallen through the cracks; and depending on your interests and level of coding ability, some could be relatively easy to fix. Do some work, make some noise, and express your interests and then whoever wants you as a minion will be more likely to find you. Whether or not coding is your forte, you can support the project in other ways as well. FreeBSD has great documentation, but it can always be improved or added to. I tend to proofread everything I read, so I've sent in a couple "bug" reports about manpage typos. I've been pleasantly surprised at both the promptness with which they were addressed and the gratitude expressed for my filing the reports. Evangelism and peer support are other great things you can do. Educate people at your school about FreeBSD and suggest ways that using FreeBSD might improve a lab/program/service. Answer questions on the -questions mailing list and/or the comp.unix.bsd.freebsd.misc newsgroup. FreeBSD is a great platform with an even greater user/developer community, so letting people know about it is always a good thing. Just a few ideas from my own experience... :) JN To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Tue Jun 18 23:35:12 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from smtp.comcast.net (smtp.comcast.net [24.153.64.2]) by hub.freebsd.org (Postfix) with ESMTP id AE19237B401 for ; Tue, 18 Jun 2002 23:35:09 -0700 (PDT) Received: from dallben (pcp529856pcs.nash01.tn.comcast.net [68.52.131.181]) by mtaout03.icomcast.net (iPlanet Messaging Server 5.1 HotFix 0.8 (built May 13 2002)) with ESMTP id <0GXX00DYBWN6AP@mtaout03.icomcast.net> for freebsd-hackers@freebsd.org; Wed, 19 Jun 2002 02:28:18 -0400 (EDT) Date: Wed, 19 Jun 2002 01:28:18 -0500 (CDT) From: "Brandon D.

Has anybody experience with this ? If you have a NEC7210 based GPIB card, I have a rudimentary userland driver for it. I use it for some HP boxes when I fiddle my timekeeping gadgets. I don't know about accessing floppies over GPIB (well, I _do_ know about the non-standard way Commodore did it but...) but if you can find the docs you can probably code it up pretty easily. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.

Very few things could work faster than lsof(1) with appropriate command-line options. I would suggest that you take the time to read the lsof manual page carefully, then try something like: lsof -nPli 4tcp:25 Of course, depending on your needs, you may want to drop the -P, -l or -n options.

As someone who has known Alfred a long time, yes, he can be an asshole, he also does a hell of a lot of work, is willing to do "grunt" work, and while these aren;t huge projects, he's filled in where needed. That says so much more for his willingness to actually do something to advance the project as a whole. > > Matthew Dillon is one of the few hackers worth his salt, what does he get in > return?

The commit bit thing has been going on ever since I can remember. If Matt wanted to leave, he would have done so long ago.

Suppose there is a process, let this process doesn't have any childs, open sockets, it has one thread, etc. But this process can malloc() memory, open local files. Let's take very simple case. Is it possible to store process state to the file (i.e. say somehow the kernel to do this), and then after rebooting restore from the file this process back to system and continue executing it? I understand that it is not very simple, but I want to know if it is possible. Are there any problem with memory addressetion? Some years ago I implemented the same thing under MS-DOS, so in general I understand the way what it should look like, and I successfuly stored process state and restored this process in MS-DOS to continue very long calculations on slow PC (this wasn't my software, so I could't patch it to store results in temporary file). Of course it is impossible to compare how I did it for MS-DOS and how it can be done on FreeBSD.

This is caused by sched_getscheduler() (in sys/posix4/p1003_1b.c) failing for non-root users: by hacking p31b_proc() to have a "read/write" flag, and a more lenient variant of CAN_AFFECT() for read operations, my JDK works fine: but I don't feel comfortable posting patches without understanding the security ramifications more clearly The manpage for sched_getscheduler() doesn't document the permissions very well, other than to defer to POSIX 1003.1b (which I don't have a copy of, and SUSv2 is less than forthcoming) I would at least have thought that any process should at least be able to get it's own scheduling parameter, and would have thought that this was _not_ a "write-style" operation. Am I right? I was also wondering if it should be allowable for a non-root process to set their scheduling parameters: I suppose this might lead to users creating processes that could starve system processes. Should this indeed be forbidden? (There's a #if 0'ed out version of CAN_AFFECT which is much less paranoid, but there's no decent comment to describe why its even there.) Can anyone shed (or even sched :-)) light on why CAN_AFFECT is defined as it is? -- Peter Edwards To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Wed Jun 19 6:47: 9 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from blackhelicopters.org (geburah.blackhelicopters.org [209.69.178.18]) by hub.freebsd.org (Postfix) with ESMTP id 3350037B40A for ; Wed, 19 Jun 2002 06:46:59 -0700 (PDT) Received: (from mwlucas@localhost) by blackhelicopters.org (8.11.6/8.11.6) id g5JDkqH37599; Wed, 19 Jun 2002 09:46:52 -0400 (EDT) (envelope-from mwlucas) Date: Wed, 19 Jun 2002 09:46:52 -0400 From: Michael Lucas To: Evan Dower Cc: freebsd-hackers@FreeBSD.ORG Subject: Re: I Volunteer Message-ID: <20020619094652.A37433@blackhelicopters.org> References: Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.2.5i In-Reply-To: ; from evantd@hotmail.com on Tue, Jun 18, 2002 at 10:35:09PM -0700 Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG On Tue, Jun 18, 2002 at 10:35:09PM -0700, Evan Dower wrote: > I don't know who might have use of my services (or what my services might be > for that matter), but I hereby offer them up.

If you hold global resources such as filehandles, shared memory you should know how they are used to make restoring them easier.

There are quite a few things that you can help with, if you're feeling like spending a bit of time in improving FreeBSD. I really do not like the term 'minion', since all contributions to the development of FreeBSD are considered valuable, important and something that both the developers and the rest of the FreeBSD users are grateful for. I'm not the one to speak as if I "represent" anyone, but all I can say is: by all means, do help in whichever ways you see fit.

A. it compiles without errors or warnings. B. it loads and unloads repeatedly without exploding my laptop. bad news is that it's utterly comatose. :-) one might argue that good news B. is dependent on the fact that this module is comatose, because once i get it to the point where it actually does something ( i am gonna try to get /dev/midistat to work first ) it will probably start trashing my laptop with great frequency. :-) the conversion to a kld was greatly facilitated by the articles in the dev handbook and on daemonnews. tnx so much to all the doc writers! i'll write one too once i get this to work. my next activity will be to compare the code in /usr/src/sys/dev/sound against the stuff that i have currently and try to ascertain what it is that i am doing wrong. if somebody with commit priveledges would get in touch with me about eventually checking this stuff in i would really appreciate it. tnx! johnu -- John L.

Some people seem to WANT arguments, and intentionally approach people whom they think will give them a challenging one. They do this to Terry and others too. I'm reminded of the Monty Python skit: "I'd like an argument, please." Alas, as in the skit, they too often wind up hurling abuse (which may have been what they really wanted to do). --Brett To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Wed Jun 19 10:19:32 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from mail04.svc.cra.dublin.eircom.net (mail04.svc.cra.dublin.eircom.net [159.134.118.20]) by hub.freebsd.org (Postfix) with SMTP id 586D537B414 for ; Wed, 19 Jun 2002 10:19:16 -0700 (PDT) Received: (qmail 23758 messnum 1152883 invoked from network[159.134.237.75/jimbo.eircom.net]); 19 Jun 2002 17:19:15 -0000 Received: from jimbo.eircom.net (HELO webmail.eircom.net) (159.134.237.75) by mail04.svc.cra.dublin.eircom.net (qp 23758) with SMTP; 19 Jun 2002 17:19:15 -0000 From: "Peter Edwards" To: "Richard Seaman, Jr." Cc: hackers@freebsd.org Subject: Re: sched_setscheduler() permissions and the linux JDK 1.4 Date: Wed, 19 Jun 2002 18:19:15 +0100 Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 8bit X-Originating-IP: 62.17.151.61 X-Mailer: Eircom Net CRC Webmail (http://www.eircom.net/) Organization: Eircom Net (http://www.eircom.net/) Message-Id: <20020619171916.586D537B414@hub.freebsd.org> Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG "Richard Seaman, Jr." wrote: > sched_setscheduler/sched_getscheduler are broken, permission wise, in > both stable and current.

I'm not aware of any standard for permissions. But, the permissions in rtprio(2) are probably right for sched_get/setscheduler and sched_get/setparam. I have a patch for the permissions in current, but this is just a temporary hack because there are deeper issues. I've attached it. > > However, the sched_XXXX functions are mostly broken anyway. > > In what way?

All the above. Its been on my "todo" list for quite a while to try to describe and fix the brokenness. The list is too long for a simple message.

Assuming you're not a committer, you need to bring it to the attention of someone who is. Add a comment with your name and contact info (as well as why you think it should be closed if it's not obvious) to the PR. Then, if the PR is assigned to anyone in particular, check with them. If not, e-mailing the appropriate list (-stable, -current, -doc, etc) with the PR number is usually sufficient.

When compiled without -pthread (ie gcc -o sigp sigp.c), the attached code behaves as expected like so: $ ./sigp 1, run 2 $ When compiled with -pthread (ie gcc -pthread -o sigp sigp.c): $ ./sigp and then it hangs. Sending it a SIGHUP from another terminal has no effect, but other likely signals (eg SIGINT) kill it. There appears to have been a thread on a closely related topic, found at (long URL): http://groups.google.com/groups?hl=en&lr=&threadm=fa.n97llov.1lict2d%40ifi.uio.no However, no information from that thread has illuminated the situation at hand. Having two interpreter executables (with and without threads) is unpalatable. Is there any way that the thread enabled interpreter can be setup to handle signals in the same way, in the absence of activated threads, as it would without thread support? (without disturbing the signal handling when threads _are_ activated, of course...) Thanks for any advice, Andrew. -- Andrew I MacIntyre "These thoughts are mine alone..."

Are there any problem with memory addressetion? Do a web search on the two terms "checkpoint restart". You can also do a web search on the term "undump". In a general sense, this won't be able to work for any process which uses sockets, because the endpoint information will not be recoverable (in case you decide to not take the "simple case" in the future). It's possible to make it (mostly) recoverable, but it requires modifications, such as pausing the TCP stack so that after reboot, but before checkpointed jobs that will be restarted are recovered, since you don't want to be sending RST packets to the peers on network connections. As a rule, most checkpoint and restart systems that you will find out there on the net when you run the search will also not support things like re-sharing of descriptors for a set of processes that have used UNIX domain sockets to pass them, maintaining proper parent/child process relationships for things like SIGCHLD, etc.. You should assume that anything you checkpoint will be restarted on another machine halfway around the planet, without any of the other local processes running. Anything having to do with pending outstanding operations (e.g. alarms, I/O, etc.) will require OS support to recover. Since it's a lot simpler to restart a long running application *almost* where it left off, most of the useful and non-invasive packages you will find from your web search will try to do a periodic snapshot of process state, and restore it from the point of last snapshot, not failure. This will also lose any implied IPC state, so it's best if the application in question is written to open any resources, access them, close them, do the long term computation, and then open and write an output file only after it's done, rather than, say, holding the output file open. If the output file is written incrementally, you will likely end up with duplicate results, otherwise. For these reasons, and others I haven't mentioned, you will probably be most happy with "undump", unless you plan on doing a large project. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Wed Jun 19 12:48:50 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from scl8out02.exodus.net (scl8out02.exodus.net [66.35.230.242]) by hub.freebsd.org (Postfix) with ESMTP id E2E5837B403 for ; Wed, 19 Jun 2002 12:48:45 -0700 (PDT) Received: from SJDCEX01.int.exodus.net ([165.193.27.80]) by SCL8OWA02.int.exodus.net with Microsoft SMTPSVC(5.0.2195.4905); Sat, 15 Jun 2002 08:51:49 -0700 X-MimeOLE: Produced By Microsoft Exchange V6.0.5762.3 content-class: urn:content-classes:message MIME-Version: 1.0 Content-Type: text/plain; charset="Windows-1252" Content-Transfer-Encoding: quoted-printable Subject: RE: sorting in C Date: Sat, 15 Jun 2002 08:51:49 -0700 Message-ID: <45258A4365C6B24A9832BFE224837D552B1233@SJDCEX01.int.exodus.net> X-MS-Has-Attach: X-MS-TNEF-Correlator: Thread-Topic: sorting in C Thread-Index: AcIUCrGmWVpTYhZMT+SPwjtA+Dn1OgAeaZkq From: "Maksim Yevmenkin" To: "Cyrille Lefevre" , "echo dev" Cc: X-OriginalArrivalTime: 15 Jun 2002 15:51:49.0600 (UTC) FILETIME=[8F86A600:01C21484] Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG On Fri, Jun 14, 2002 at 07:06:06AM +0000, echo dev wrote: > > I am pooling in as many different ways of sorting data in C i can = anyone=20 > > have a fav???

The problem with sliding the label is that you have to also initialize euip to NULL at the beginning and then check its value before calling uifree() so that you don't pass garbage to uifree(). > /* > * Handle deferred decrement of ref counts. > */ > if (textvp != NULL) > vrele(textvp); > #ifdef KTRACE > if (tracevp != NULL) > vrele(tracevp); > #endif > pargs_drop(oldargs); > > part... should that be before or after exec_fail_dealloc? I hadn't looked at this before ... I think the proper solution is to move the fdcheckstd() test to the beginning of its enclosing "if" block so that textvp and tracevp are only set after the test is passed. I'd rearrange the code so that all the cleanup at the end is done in the reverse order that the allocations were done at the beginning. Doing so allowed me to see that there is also a potential leak of newargs.

Too bad he's sick of networking. There a lot of intersting code that could be implemented in the main line FreeBSD that would be really beneficial, overall. The memory compaction is an intersting problem, but might require some really serious changes, since you could not compact anything that was in the compaction code path. Reclaiming large sections of kernel memory (basically defragging it) would help those people who want to build camera and other drivers that need to call for a contigmalloc, and which are expected to be loaded potentially well after boot time. A similar set of changes would be necessary to handle kernel paging (basically, it breaks down into section attributes to allow or to disallow paging of code/data in specific ELF sections). I would say, though, that they were two seperate projects (but the second one would leverage the first to greater benefit). Most of the VFS stuff is really VM stuff. An interesting VFS project would be to create a pseudo-device that would proxy VOP requests to/from user space, so that you could develop stacking layers in user space. THis would also very quickly and concisely identify where things in the current VFS/VM interaction make assumptions that they ought not to be making. The OpenAFS code is not very interesting, to me. However, if you have an AFS license there, then your location is probably one of the few places the work could be done, so my preferences not withstanding, as long as you have a real AFS to run against for testing, then the OpenAFS could be a good project that could happen nowhere else. > What do people here think?

I hesistate to mention this; you would have to see if the University of Guelph is working on it already. But... how about an NFSv4 implementation for FreeBSD? At 2 hours a day for 6 months, you are talking 260 man hours, approximately, or the equivalent of 1/8th of a year... 1.5 man months. So whatever project that's picked will have to fit in that wrapper. If the 2 hours a day includes the data analysis and writeup, then you are probably talking about half that time for the actual project work. This is almost too little to take on most kernel projects, if it's not in an area that you're already familiar with, like networking, in this students case.

The first to demonstrate his background, and potential related areas that he might be interested in. The second was I think he could be convinced to do networking again if it was "intreesting", or could be made to seem interesting. So if you have ideas in this area, feel free to share ;) > The memory compaction is an intersting problem, but might require > some really serious changes, since you could not compact anything > that was in the compaction code path.

Exactly. This is why I brought it up. I personally have been bit by not being able to allocate large, unfragmented, blocks of physical RAM. I think this is potentially of the greatest benefit to the project, and the closest to VM work that is reasonable given the other criteria, but I don't see the data gathering aspects for him in this. Would it be possible that such a defragmentation could 'recolor' pages? Or are pages allocated with optimal colors already? One could gather data on cache performance at that point. > Most of the VFS stuff is really VM stuff.

We have an intense interest in OpenAFS, and a license, but . Also it appears that OpenAFS is going along well on its own at this point. If this goes well for everyone, it could very easily be the start of many more such projects. Potentially on a continual basis. That is my real goal here. -- David Cross | email: crossd@cs.rpi.edu Lab Director | Rm: 308 Lally Hall Rensselaer Polytechnic Institute, | Ph: 518.276.2860 Department of Computer Science | Fax: 518.276.4033 I speak only for myself. | WinNT:Linux::Linux:FreeBSD To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Wed Jun 19 20:47:19 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from outhub2.tibco.com (outhub2.tibco.com [63.100.100.156]) by hub.freebsd.org (Postfix) with ESMTP id 5B82637B411 for ; Wed, 19 Jun 2002 20:47:15 -0700 (PDT) Received: by outhub2.tibco.com; id UAA09246; Wed, 19 Jun 2002 20:47:17 -0700 (PDT) Received: from na-h-inhub2.tibco.com(10.106.128.34) by outhub2.tibco.com via smap (V4.1) id xma009223; Wed, 19 Jun 02 20:46:22 -0700 Received: from mail1.tibco.com (nsmail2.tibco.com [10.106.128.42]) by na-h-inhub2.tibco.com (8.12.2/8.12.2) with ESMTP id g5K3a7Fl022587 for ; Wed, 19 Jun 2002 20:36:07 -0700 (PDT) Received: from tibco.com ([10.105.146.230]) by mail1.tibco.com (Netscape Messaging Server 4.15) with ESMTP id GXZJT700.4RQ; Wed, 19 Jun 2002 20:46:19 -0700 Message-ID: <3D114FE7.3020304@tibco.com> Date: Wed, 19 Jun 2002 20:45:43 -0700 From: "Aram Compeau" User-Agent: Mozilla/5.0 (Windows; U; WinNT4.0; en-US; rv:0.9.4) Gecko/20011019 Netscape6/6.2 X-Accept-Language: en,zh,fr,ja,ko MIME-Version: 1.0 To: Terry Lambert Cc: "David E.

Here it > is: Your patch also looks like it should fix the bug. I prefer my patch, though, because I think the resultant code is structured better and should be easier to understand. For instance, the reason for the assignment to oldcred in the "if (error != 0)" block in your patch is not immediately obvious. My version should probably run at tiny bit faster as well, though this is unlikely to be measureable. BTW, it is possible to further optimize the code if both instances of: p->p_ucred = newcred; newcred = NULL; are changed to: p->p_ucred = newcred; newcred = oldcred; This allows: if (newcred == NULL) crfree(oldcred); else crfree(newcred); to be simplified to: crfree(newcred); and the initialization of newcred in its declaration could be eliminated. I'd rename newcred to something else like cred or tmpcred that would hopefully be less likely to cause confusion. > Index: sys/kern/kern_exec.c > =================================================================== > RCS file: /home/ncvs/src/sys/kern/kern_exec.c,v > retrieving revision 1.164 > diff -u -r1.164 kern_exec.c > --- sys/kern/kern_exec.c 7 Jun 2002 05:41:27 -0000 1.164 > +++ sys/kern/kern_exec.c 16 Jun 2002 14:14:37 -0000 > @@ -133,7 +133,7 @@ > struct image_params image_params, *imgp; > struct vattr attr; > int (*img_first)(struct image_params *); > - struct pargs *oldargs, *newargs = NULL; > + struct pargs *oldargs=NULL, *newargs = NULL; > struct procsig *oldprocsig, *newprocsig; > #ifdef KTRACE > struct vnode *tracevp = NULL; > @@ -383,8 +383,10 @@ > #endif > /* Make sure file descriptors 0..2 are in use. */ > error = fdcheckstd(td); > - if (error != 0) > - goto exec_fail_dealloc; > + if (error != 0) { > + oldcred = NULL; > + goto done1; > + } > /* > * Set the new credentials. > */ > @@ -467,6 +469,7 @@ > p->p_args = newargs; > newargs = NULL; > } > +done1: > PROC_UNLOCK(p); > > /* > @@ -476,7 +479,6 @@ > crfree(oldcred); > else > crfree(newcred); > - KASSERT(newargs == NULL, ("leaking p_args")); > /* > * Handle deferred decrement of ref counts. > */ > @@ -486,7 +488,10 @@ > if (tracevp != NULL) > vrele(tracevp); > #endif > - pargs_drop(oldargs); > + if (oldargs != NULL) > + pargs_drop(oldargs); > + if (newargs != NULL) > + pargs_drop(newargs); > > exec_fail_dealloc: > To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Thu Jun 20 1:38: 1 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from harrier.mail.pas.earthlink.net (harrier.mail.pas.earthlink.net [207.217.120.12]) by hub.freebsd.org (Postfix) with ESMTP id E465837B40C for ; Thu, 20 Jun 2002 01:37:48 -0700 (PDT) Received: from pool0062.cvx22-bradley.dialup.earthlink.net ([209.179.198.62] helo=mindspring.com) by harrier.mail.pas.earthlink.net with esmtp (Exim 3.33 #2) id 17KxRj-0006CH-00; Thu, 20 Jun 2002 01:37:40 -0700 Message-ID: <3D119425.7EF9BE3E@mindspring.com> Date: Thu, 20 Jun 2002 01:36:53 -0700 From: Terry Lambert X-Mailer: Mozilla 4.7 [en]C-CCK-MCD {Sony} (Win98; U) X-Accept-Language: en MIME-Version: 1.0 To: Aram Compeau Cc: "David E.

LRP gets rid of the need to run network processing in kernel threads, in order to get parallel operation on SMP systems; so long as the interrupt processing load is balanced, it's possible to handle interrupts in an overlapped fashion. Right now, there are four sets of source code: SunOS 4.1.3_U1, FreeBSD 2.2-BETA, FreeBSD 4.0, FreeBSD 4.3. The first three are from Rice University. The fourth is from Duke University, and is a port forward of the 4.0 Rice code. The Rice code, other than the FreeBSD 2.2-BETA, is unusable. It mixes in an idea called "Resource Containers" (RESCON), that is really not very useful (I can go into great detail on this, if necessary). It also has a restrictive license. The FreeBSD 2.2-BETA implementation has a CMU MACH style license (same as some FreeBSD code already has). The LRP implementation in all these cases is flawed, in that it assumes that the LRP processing will be universal across an entire address family, and the experimental implementation loads a full copy of the AF_INET stack under another family name. A real integration is tricky, including credentials on accept calls, an attribute on the family struct, to indicate that it's LRP'ed, so that common subsystems can behave very differently, support for Accept filters and othe Kevents, etc.). LRP gives a minimum of a factor of 3 improvement in connections per second, without the SYN cache code involved at all, through an overall reduction in processing latency. It also has the effect of preventing "receiver livelock". http://www.cs.rice.edu/CS/Systems/LRP/ http://www.cs.duke.edu/~anderson/freebsd/muse-sosp/readme.txt ---------------- TCP Rate Halving ---------------- I would like to see FreeBSD support TCP Rate Halving, and idea from the Pittsburgh Cupercomputing Center (PSC) at Carengie Mellon University (CMU). These are the people who invented "traceroute". TCP Rate halving is an alternative to the RFC-2581 Fast Recovery algorithm for congestion control. It effectively causes the congestion recovery to be self-clocked by ACKs, which has the overall effect of avoiding the normal burstiness of TCP recovery following congestion. This builds on work by Van Jacobsen, J. Hoe, and Sally Floyd. Their current implementation is for NetBSD 1.3.2. http://www.psc.edu/networking/rate_halving.html --------------- SACK, FACK, ECN --------------- Also from PSC at CMU. SACK and FACK are well known. It's annnoying that Luigi Rizzo's code from 1997 or so was never integrated into FreeBSD. ECN is an implementation of Early Congestion Notification. http://www.psc.edu/networking/tcp.html ---- VRRP ---- There is an implementation of a real VRRP for FreeBSD available; it is in ports. This is a real VRRP (Virtual Router Redundancy Protocol), not like the Linux version which uses the multicast mask and thus loses multicast capability. There are intersting issues in actual deployment of this code; specifically, the VMAC that needs to be used in order to logically seperate virtual routers is not really implemented well, so there are common ARP issues. There are a couple of projects that one could take on here; by far, the most interesting (IMO) would be to support multiple virtual network cards on a single physical network card. Most of the Gigabit Ethernet cards, and some of the 10/100Mbit cards, can support multiple MAC addresses (the Intel Gigabit card can support 16, the Tigon III supports 4, and the Tigone II supports 2). The work required would be to support the ability to have a single driver, single NIC, multiple virtual NICs. There are also interesting issues, like being able to selectively control ARP response from a VRRP interface which is not the master interface. This has intersting implications for the routing code, and for the initialization code, which normally handles the gratuitous ARP. More information can be found in the VRRP RFC, RFC-2338. ---------- TCP Timers ---------- I've discussed this before in depth. Basically, the timer code is very poor for a large number of connections, and increasing the size of the callout wheel is not a real/reasonable answer. I would like to see the code go back to the BSD 4.2 model, which is a well known model. There is plenty of prior art in this area, but the main thing that needs to be taken from the BSD 4.2 is per interval timer lists, so that the list scanning, for the most part, scans only those timers that have expired (+ 1). Basically, a TAILQ per interval for ficed interval timers. A very obvious way to measure the performance improvement here is to establish a very large number of connections. If you have 4G of memory in an IA32 machine, you should have no problem getting to 300,000 connections. If you really work at it, I have been able to push this number to 1.6 Million simultaneous connections. --------------- SMP Safe Queues --------------- For simple queue types, it should be possible to make queueing and dequing an intrinsically atomic operation. This basically means that the queue locking that is being added to make the networking code SMP safe, is largely unnecessary, and is caused solely by the fact that the queue macros themselves are not being properly handled through ordering of operations, rather than being locked around. In theory, this is also possible for a "counted queue". A "counted queue" is a necessary construct for RED queueing, which needs to maintain a moving average for comparison to the actual queue depth, so that it can do RED (Random Early Drop) of packets. --- WFS --- Weighted fair share queueing is a method of handling scheduling of processes, such that the kernel processing. This isn't technically a networking issue. However, if the programs in user space which are intended to operate (or, if you are a 5.x purist, the kernel threads in kernel space, if you pull an Ingo Mollnar and cram everything that shouldn't be in the kernel, into the kernel) do not remove data from the input processing queue fast enough, you will still suffer from receiver livelock. Basically, you need to be able to run the programs with a priority, relative to interrupt processing. Some of the work that Jon Lemon and Luigi Rizzo have done in this area is interesting, but it's not sufficient to resolve the problem (sorry guys). Unfortunately, they don't tend to run their systems under breaking point stress, so they don't see the drop-off in performance that happens at high enough load.To be able to test this, you would have to have a lab with the ability to throw a large number of clients against a large number of servers, with the packets transiting an applicaiton in a FreeBSD box, at close to wire speeds. We are talking at least 32 clients and servers, unless you have access to purpose built code (it's easier to just throw the machines at it, and be done with it). --- --- --- Basically, that's my short list. There are actually a lot more things that could be done in the networking area; there are things to do in the routing area, and things to do with RED queueing, and things to do with resource tuning, etc., and, of course, there's the bugs that you normally see in the BSD stack only when you try to dothings like open more than 65535 outbound connections from a single box, etc.. Personally, I'm tired of solving the same problems over and over again, so I'd like to see the code in FreeBSD proper, so that it becomes part of the intellectual commons. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Thu Jun 20 2: 9:13 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from cc-gw.1anetworks.net (cc-gw.1anetworks.net [193.243.179.83]) by hub.freebsd.org (Postfix) with SMTP id 0A31D37B409 for ; Thu, 20 Jun 2002 02:09:07 -0700 (PDT) Received: from BRI (brian.1anetworks.net [212.36.98.200]) by parma.1anetworks.net (8.9.3+Sun/8.9.3) with SMTP id KAA28434 for ; Thu, 20 Jun 2002 10:09:04 +0100 (BST) From: "Bri" To: Subject: FW: Problem: unregistered isr number 18 Date: Thu, 20 Jun 2002 10:05:13 +0100 Message-ID: MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit X-Priority: 3 (Normal) X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook IMO, Build 9.0.2416 (9.0.2910.0) X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2600.0000 Importance: Normal Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG wondering if you guys can shed any light on this matter.

I have had it detect an ip once but only once and I must of left it detecting one for like 12hrs which isn't good. a cry for help Bri, To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-sparc" in the body of the message To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Thu Jun 20 2:14:10 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from relay1.ntu-kpi.kiev.ua (www.ntu-kpi.kiev.ua [212.111.192.161]) by hub.freebsd.org (Postfix) with ESMTP id F194037B409 for ; Thu, 20 Jun 2002 02:14:03 -0700 (PDT) Received: from comsys.ntu-kpi.kiev.ua (eth0.comsys.ntu-kpi.kiev.ua [10.0.1.184]) by relay1.ntu-kpi.kiev.ua (Postfix) with ESMTP id 5AAF11990C for ; Thu, 20 Jun 2002 12:14:01 +0300 (EEST) Received: from pm5149 (pm514-9.comsys.ntu-kpi.kiev.ua [10.18.54.109]) by comsys.ntu-kpi.kiev.ua (8.11.6/8.11.6) with SMTP id g5K9HNw58500 for ; Thu, 20 Jun 2002 12:17:23 +0300 (EEST) Message-ID: <007f01c21839$8a0b3cf0$6d36120a@pm5149> From: "Andrey Simonenko" To: References: <006401c21793$30721750$6d36120a@pm5149> <20020619141241.GO43253@cicely5.cicely.de.lucky.freebsd.hackers> Subject: Re: Is it possible to store process state and then restore process Date: Thu, 20 Jun 2002 12:04:52 +0300 MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 5.00.2919.6700 X-MimeOLE: Produced By Microsoft MimeOLE V5.00.2919.6700 Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG ----- Original Message ----- From: "Bernd Walter" Newsgroups: lucky.freebsd.hackers Sent: Wednesday, June 19, 2002 5:16 PM Subject: Re: Is it possible to store process state and then restore process > Some programms dump theirself into an obj file after initialization. > If you hold global resources such as filehandles, shared memory you > should know how they are used to make restoring them easier. > The kernel has no support to help you here. > I meaned _potential_ ability of FreeBSD kernel to dump a process state (image) and when it is needed to restore process image back to the system and restored process should continue its executing.

I thought the strength of uw-imap was that it was fairly easy to configure for a machine with local users. The same certainly couldn't be said for Cyrus. Heck, I nearly slit my own wrists out of frustration trying to get Cyrus working. Doesn't help that its online documentation is poo either.

Something I'd like to see which is unfortunatly network releated is ng_ip, ng_tcp, and ng_udp netgraph modules. Since the networking code already exists (though it's probably got a number of layering violations in it that would need to be sorted out) this would be more of an infrastructure project then a networking project. It would have things to measure (comparative throughput and latency, for example.) If these modules were available, netgraph would become much more intresting as a basis for network research (say building distributed simulators). Later researchers could add ng_tcp_reno, ng_tcp_vegas, or even ng_tca_daytona (the messed up "accelerated" tcp which acks each byte seperatly.) -- Brooks --=20 Any statement of the form "X is the one, true Y" is FALSE.

I'm not one who has hacked on mutt, nor who really intends to (if I can avoid it, I will), so hence the reason for this post. So this post is directed at those people who have some extra time on their hands and are looking to make some sort of contribution to FreeBSD, but aren't prepared (or don't want to) muck in the kernel source. 1) The first feature is a persistent-thread-delete. This idea was given by Jonathan Mini at Usenix. I'm not aware of any client that supports this right now, but such a client may exist (in any case, it would be cool if mutt did it). What this does is pretty straightforward: I see a thread with subject "foo." I don't like it. I really don't like it. I hit a key combination such as, I don't know, CTRL+B (or something not bound yet), and not only is the entire thread instantly marked for deletion, but a carefully crafted rule is also dropped into a sh*tlist file (that can be handled by procmail?) which will ensure that all _future_ mailings that are in response to said thread will immediately be marked for deletion, or merely filtered. Hence, "persistent thread suppression/deletion." 2) An optional feature that would, when you hit 'y' to send that Email off, attempt to roughly analyze your message and present an "Are you sure you want to send this Email, it contains potentially inflammatory content?" confirmation request, based on the content of the message. I believe Eudora Lite has this sort of thing where if you key in something that looks offensive/like a flame, it will generate a popup with a warning like "Warning: this Email may offend the average reader, are you sure you went to send it?" I think this would help some of us out with controlling our tempers. If you want to make this extra cool, you could have a system where Email can be classified as "INFLAMMATORY" and "REALLY INFLAMMATORY," and the "REALLY INFLAMMATORY" Email would not only generate the warning, but would also set off a timer and only blast the Email away in N minutes, unless it is cancelled prior to the blastoff time. Anyway, I really think that (1) would be extremely useful. As for (2), well, it's kind of funny. :-) Cheers, -- Bosko Milekic bmilekic@unixdaemons.com bmilekic@FreeBSD.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Thu Jun 20 12:36:46 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from edgemaster.zombie.org (ip68-13-69-9.om.om.cox.net [68.13.69.9]) by hub.freebsd.org (Postfix) with ESMTP id AF73E37B400 for ; Thu, 20 Jun 2002 12:36:42 -0700 (PDT) Received: by edgemaster.zombie.org (Postfix, from userid 1001) id 245E466B04; Thu, 20 Jun 2002 14:36:41 -0500 (CDT) Date: Thu, 20 Jun 2002 14:36:41 -0500 From: Sean Kelly To: Bosko Milekic Cc: freebsd-hackers@freebsd.org Subject: Re: Some small projects for mutt(1) Message-ID: <20020620193641.GA63920@edgemaster.zombie.org> References: <20020620152454.A23499@unixdaemons.com> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline In-Reply-To: <20020620152454.A23499@unixdaemons.com> User-Agent: Mutt/1.5.1i Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG On Thu, Jun 20, 2002 at 03:24:54PM -0400, Bosko Milekic wrote: > > Hi, > > Two ideas have come up recently to extend the features of the mutt(1) > Email client.

These are dedicated NFS/SMB servers. Physically they are 1U boxes with four 70GB IDE disks on them (wd0, wd1, wd2, wd3). They have Pentium (P55C) processors, 128MB of RAM, an on-board fxp device, no slots, and no removable media devices, all this on what appears to be a semi-custom motherboard. We managed to find a serial console with the help of a multimeter and an oscilloscope. The OS appears to be a stripped-down FreeBSD 3.X...they have some kind of concatenated disk driver that seems similar to ccd(4). For various reasons, we're trying to figure out how to get a stock FreeBSD 4-STABLE on them. We tossed in a scratch disk with 4.5-STABLE as the primary master disk; the machine wouldn't even give a loader prompt. We also tried booting with the existing wd0 and wd1, and our disk on the secondary master; we could boot, but got a kernel panic during an attempted boot to single-user mode...I suspect in the concatenated disk driver trying to do some consistency checking. I should mention that with all four of the original disks installed, it functions properly, if slowly, as an NFS server. We're trying not to wipe out the existing boot disk until we have at least a warm, furry feeling that this is going to work. We haven't gotten that yet. In theory we could put a populated obj/ tree on the existing disks and use this to do a installkernel/installworld, but this commits us to a course of action really early without an easy way to back out if something goes wrong (see last paragraph). Has anyone played around with one of these boxes? Thanks in advance! Bruce. PS. It's crossed my mind that the staff time involved in making this work could quickly exceed the cost of buying equivalent (maybe even better) "normal" hardware. :-) --==_Exmh_-1928488758P Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.7 (FreeBSD) Comment: Exmh version 2.5+ 20020506 iD8DBQE9EjJu2MoxcVugUsMRAqhqAJ91kyvDsysZp3+Dh5iwsBhr9NzGTACgso9Q /e+5Eu9/NrqQZgELmD1ZClo= =CuUG -----END PGP SIGNATURE----- --==_Exmh_-1928488758P-- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Thu Jun 20 13: 7: 2 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from mx01-a.netapp.com (mx01-a.netapp.com [198.95.226.53]) by hub.freebsd.org (Postfix) with ESMTP id 09E5437B669 for ; Thu, 20 Jun 2002 13:04:51 -0700 (PDT) Received: from frejya.corp.netapp.com (frejya [10.10.20.91]) by mx01-a.netapp.com (8.12.3/8.12.3/NTAP-1.4) with ESMTP id g5KK4lAg021607; Thu, 20 Jun 2002 13:04:47 -0700 (PDT) Received: from elwood-fe.eng (localhost [127.0.0.1]) by frejya.corp.netapp.com (8.12.2/8.12.2/NTAP-1.4) with ESMTP id g5KK4k0E001880; Thu, 20 Jun 2002 13:04:47 -0700 (PDT) Received: from localhost (kmacy@localhost) by elwood-fe.eng (8.11.6+Sun/8.11.6) with ESMTP id g5KK4b809858; Thu, 20 Jun 2002 13:04:45 -0700 (PDT) Date: Thu, 20 Jun 2002 13:04:37 -0700 (PDT) From: Kip Macy To: "Bruce A.

They don't have a standard BIOS, so they don't support the standard routines that the newer bootloader expects (e.g. memory sizing). If you have more questions feel free to follow up off list - I doubt the particulars of these boards or CDS' custom/hacked version of FreeBSD 3.0 are of much interest to those on the list. If need be I can contact the person who designed the board - I know it is a bit of a kludge but he was working on a very limited time frame. Also you'll find that the MAC address is stored on the boot ROM. Maxtor has moved from FreeBSD to the Windows SAK so the newer boxes are likely to have full BIOS support (they could not keep any of the CDS developers to maintain the FreeBSD code base).

Hence, "persistent thread > suppression/deletion." This shouldn't be hard to glue together without modifying mutt itself. Make a little program, foo, that takes the message on stdin, passes it through "formail -x subject", massages it into a procmail rule, and appends it to some procmail rule file. The "massage" step should include escaping characters that have special meanings in procmail regexps, and adding something like (Re: *)? at the beginning of the subject when appropriate.

While I think LRP and TCP Rate Halving are quite interesting, I think tackling the SMP Safe Queues makes the best use my resources. I fear that testing some of the other items requires setups that are not feasible for me.

Could you elaborate briefly on what you'd like to see worked on with
respect to this? I don't want you to spend a lot of time describing
anything, but I am curious. I don't generally have large blocks of spare
time, but could work on something steadily with a low flame.

LRP
---

I would like FreeBSD to support LRP (Lazy Receiver Processing),
an idea which came from the Scala Server Project at Rice
University.

LRP gets rid of the need to run network processing in kernel
threads, in order to get parallel operation on SMP systems;
so long as the interrupt processing load is balanced, it's
possible to handle interrupts in an overlapped fashion.

Right now, there are four sets of source code: SunOS 4.1.3_U1,
FreeBSD 2.2-BETA, FreeBSD 4.0, FreeBSD 4.3.  The first three
are from Rice University.  The fourth is from Duke University,
and is a port forward of the 4.0 Rice code.

The Rice code, other than the FreeBSD 2.2-BETA, is unusable.
It mixes in an idea called "Resource Containers" (RESCON),
that is really not very useful (I can go into great detail on
this, if necessary).  It also has a restrictive license.  The
FreeBSD 2.2-BETA implementation h
as a CMU MACH style license
(same as some FreeBSD code already has).

The LRP implementation in all these cases is flawed, in that
it assumes that the LRP processing will be universal across
an entire address family, and the experimental implementation
loads a full copy of the AF_INET stack under another family
name.  A real integration is tricky, including credentials on
accept calls, an attribute on the family struct, to indicate
that it's LRP'ed, so that common subsystems can behave very
differently, support for Accept filters and othe Kevents, etc.).

LRP gives a minimum of a factor of 3 improvement in connections
per second, without the SYN cache code involved at all, through
an overall reduction in processing latency.  It also has the
effect of preventing "receiver livelock".

----------------
TCP Rate Halving
----------------

I would like to see FreeBSD support TCP Rate Halving, and idea
from the Pittsburgh Cupercomputing Center (PSC) at Carengie
Mellon University (CMU).

These are the people who invented "traceroute".

TCP Rate halving is an alternative to the RFC-2581 Fast Recovery
algorithm for congestion control.  It effectively causes the
congestion recovery to be self-clocked by ACKs, which has the
overall effect of avoiding the normal burstiness of TCP recovery
following congestion.

This builds on work by Van Jacobsen, J. Hoe, and Sally Floyd.

Their current implementation is for NetBSD 1.3.2.

tml

---------------
SACK, FACK, ECN
---------------

Also from PSC at CMU.

SACK and FACK are well known.  It's annnoying that Luigi Rizzo's
code from 1997 or so was never integrated into FreeBSD.

ECN is an implementation of Early Congestion Notification.

----
VRRP
----

There is an implementation of a real VRRP for FreeBSD available;
it is in ports.

This is a real VRRP (Virtual Router Redundancy Protocol), not
like the Linux version which uses the multicast mask and thus
loses multicast capability.

There are intersting issues in actual deployment of this code;
specifically, the VMAC that needs to be used in order to
logically seperate virtual routers is not really implemented
well, so there are common ARP issues.

There are a couple of projects that
 one could take on here; by
far, the most interesting (IMO) would be to support multiple
virtual network cards on a single physical network card.  Most
of the Gigabit Ethernet cards, and some of the 10/100Mbit cards,
can support multiple MAC addresses (the Intel Gigabit card can
support 16, the Tigon III supports 4, and the Tigone II supports
2).

The work required would be to support the ability to have a
single driver, single NIC, multiple virtual NICs.

There are also interesting issues, like being able to selectively
control ARP response from a VRRP interface which is not the
master interface.  This has intersting implications for the
routing code, and for the initialization code, which normally
handles the gratuitous ARP.  More information can be found in
the VRRP RFC, RFC-2338.

----------
TCP Timers
----------

I've discussed this before in depth.  Basically, the timer code
is very poor for a large nu
mber of connections, and increasing
the size of the callout wheel is not a real/reasonable answer.

I would like to see the code go back to the BSD 4.2 model, which
is a well known model.  There is plenty of prior art in this area,
but the main thing that needs to be taken from the BSD 4.2 is per
interval timer lists, so that the list scanning, for the most part,
scans only those timers that have expired (+ 1).  Basically, a
TAILQ per interval for ficed interval timers.

A very obvious way to measure the performance improvement here is
to establish a very large number of connections.  If you have 4G
of memory in an IA32 machine, you should have no problem getting
to 300,000 connections.  If you really work at it, I have been
able to push this number to 1.6 Million simultaneous connections.


---------------
SMP Safe Queues
---------------

For simple queue types, it should be possible to make queueing
and dequi
ng an intrinsically atomic operation.

This basically means that the queue locking that is being added
to make the networking code SMP safe, is largely unnecessary,
and is caused solely by the fact that the queue macros themselves
are not being properly handled through ordering of operations,
rather than being locked around.

In theory, this is also possible for a "counted queue".  A
"counted queue" is a necessary construct for RED queueing,
which needs to maintain a moving average for comparison to
the actual queue depth, so that it can do RED (Random Early
Drop) of packets.

---
WFS
---

Weighted fair share queueing is a method of handling scheduling
of processes, such that the kernel processing.

This isn't technically a networking issue.  However, if the
programs in user space which are intended to operate (or, if
you are a 5.x purist, the kernel threads in kernel space, if
you pull an Ingo Mollnar an
d cram everything that shouldn't
be in the kernel, into the kernel) do not remove data from
the input processing queue fast enough, you will still suffer
from receiver livelock.  Basically, you need to be able to
run the programs with a priority, relative to interrupt processing.

Some of the work that Jon Lemon and Luigi Rizzo have done in
this area is interesting, but it's not sufficient to resolve
the problem (sorry guys).  Unfortunately, they don't tend to
run their systems under breaking point stress, so they don't
see the drop-off in performance that happens at high enough
load.To be able to test this, you would have to have a lab
with the ability to throw a large number of clients against
a large number of servers, with the packets transiting an
applicaiton in a FreeBSD box, at close to wire speeds.  We
are talking at least 32 clients and servers, unless you have
access to purpose built code (it's easier to just throw the

machines at it, and be done with it).

---
---
---

Basically, that's my short list.  There are actually a lot more
things that could be done in the networking area; there are things
to do in the routing area, and things to do with RED queueing, and
things to do with resource tuning, etc., and, of course, there's
the bugs that you normally see in the BSD stack only when you try
to dothings like open more than 65535 outbound connections from a
single box, etc..

Personally, I'm tired of solving the same problems over and over
again, so I'd like to see the code in FreeBSD proper, so that it
becomes part of the intellectual commons.

Also, maildirs are a mediocre idea for general use, and a horrible idea for high volume mail spools. The whole idea behind IMAP is for the mail to reside on the mail server, not a user's workstation. Maildirs eat inodes like nobody's business. If you're using FFS to host a fairly high traffic mail spool you'll probably need to newfs your filesystem with a /ton/ of inodes. The only solution is to use a filesystem which dynamically allocates inodes like XFS. Cyrus uses a much more efficient storage mechanism. Brandon D.

I haven't taken a look at your patch. I was working on something else and already had a patch for it, before I saw yours. I sent it as a reference because there was something in the thread about leaking p_args. I really don't care which patch makes it into the tree. If it solves the problem, it solves the problem.

The client IP address, and the PID of the ftpd child that serves it. The hash at the beginning of the lists serves as a minor assistance in splitting the 2^32 address space in smaller chunks so that we don't end up with a singly linked list of a few thousand entries. addrhash % % .------------------. .------------------. 0 [ ]----->| struct childaddr |------->| struct childaddr |----- ... 1 [ ] |==================| |==================| 3 [ ] | in_addr ca_addr | | in_addr ca_addr | 4 [ ] | int ca_count | | int ca_count | 5 [ ] | LIST(pids) |--+ | LIST(pids) |--+ ... [ ] `------------------' | `------------------' | 65535 [ ] | | .-----------------. | .-----------------. | | struct childpid |<--+ | struct childpid |<--+ +--|=================| +--|=================| | | pid_t cp_pid | | | pid_t cp_pid | | `-----------------' | `-----------------' | | +->.-----------------. +-> ... | struct childpid | +--|=================| | | pid_t cp_pid | | `-----------------' | +-> ... A simple hash function, can be used in selecting which entry of the addrhash[] array points to the head of the proper list. The first level lists are lists of IP addresses, stored in ca_addr, and the second level of lists contain just the process ID of the child that serves a client from that address. The ca_count field of the address structure can be used to quickly find out if more clients are allowed or not, without doing a LIST_FOREACH() every time we want to see if another client socket can be accepted or dropped. I am not sure if using simple lists instead of some more sophisticated scheme is OK in this case, since I don't have a multi-thousand FTP server handy to test the patches. The inetd discussion brought this up from old things I had been thinking about, and I wondered, is there any case we could make ftpd limit client sockets per IP address too? And if that is feasible, could inetd and ftpd be made to use the same limiting code (instead of rolling two different versions), reducing code duplication? There is also the following problem, that I am not sure if I have solved it correctly. If the parent process plays around with those hashes and structures, then a signal handler that calls reapchild() to remove parts of those structures can probably do a lot of harm. The race condition seems easy to fix if I use something like: nosignals(); /* Fool around with the structures. */ signals(); Where signals() and nosignals() use sigaction() to block & unblock the signals that ftpd already installs a handler for. Does this all sound reasonable? Below is a prototype I'm playing the last few days with, trying to make something that implements the above scheme using macros. Now, what do you all think about this?

The online documentation sucks, but once you understand that you have to use an admin program (cyradm) that has to be able to authenticate to the server in order to manage it, it's not very hard at all. The main problem with UW-IMAP is that it has some serious bugs; not only are there security bugs, but there are tons of bugs in the user libraries -- which is what most people are using for web based mail clients, and other programs... like "Pine". The main problem is that there are a lot of instances where it is possible to result in calling unintialized function pointers when you attempt to access a mailbox provider type. The easiest way to see this is to make the function pointer containing struct into a pure virtual base class, each provider into a implementation class for that base class, and then pass around pointers to the provider class coerced to the virtual base class. You'll see all sorts of errors reported by the compiler about the use of a member of a class that can't be, or for which there is not a member function defined. A long time ago, I did this exercise for a commercial company, and found no less than 150 instances where this type of problem existed in the UW IMAP code. My personal recommendation, having contributed patches to both server maintainers, and used both servers in a commercia setting, is that the Cyrus IMAP server is far and away the better code base. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Thu Jun 20 19:18: 5 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from warez.scriptkiddie.org (uswest-dsl-142-38.cortland.com [209.162.142.38]) by hub.freebsd.org (Postfix) with ESMTP id 4F19037B403 for ; Thu, 20 Jun 2002 19:17:36 -0700 (PDT) Received: from [192.168.69.11] (unknown [192.168.69.11]) by warez.scriptkiddie.org (Postfix) with ESMTP id D464462D1A; Thu, 20 Jun 2002 19:17:31 -0700 (PDT) Date: Thu, 20 Jun 2002 19:22:40 -0700 (PDT) From: Lamont Granquist To: Terry Lambert Cc: Jason Andresen , "Brandon D.

Not FreeBSD, but it's possible to reconfigure Apache. The way you would deal with this would be to tell Apache that it was an HTTP 1.0 server, since chunking is an HTTP 1.1 feature. The only place this is an issue is if you need to reuse an HTTP connection, and that only occurs in HTTP 1.1 when you are doing pipelining. Everywhere else, you can indicate an end of data by having the server close the connection. Thus you do not need to use chunking in order to get around the fact that the CGI was written by someone who did not attach a proper "Content-Length:" header because they were too lazy to determine ahjead of time how much data they would be putting out. The exploit is chunking from the client to the server. I guess you would have to endure that Apache in 1.0 mode refused chunked data in POST's, etc. (last time I looked at the source code, I thought it did). This won't work if you are requiring 1.1 features for your applciation, but in most cases, no one uses these features much anyway. Though turning this off if you have a Netscaler or a similar connection reusing cache might drop your overall throughput, so if you are over the border on that, you may want to take that into account (most people don't know what their web servers are doing anyway, so it's probably never going to make a difference for you, anyway). -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Thu Jun 20 20:16:39 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from avocet.mail.pas.earthlink.net (avocet.mail.pas.earthlink.net [207.217.120.50]) by hub.freebsd.org (Postfix) with ESMTP id A7A1B37B407 for ; Thu, 20 Jun 2002 20:16:30 -0700 (PDT) Received: from pool0544.cvx21-bradley.dialup.earthlink.net ([209.179.194.34] helo=mindspring.com) by avocet.mail.pas.earthlink.net with esmtp (Exim 3.33 #2) id 17LEuN-0003Cm-00; Thu, 20 Jun 2002 20:16:28 -0700 Message-ID: <3D129A60.99AA2608@mindspring.com> Date: Thu, 20 Jun 2002 20:15:44 -0700 From: Terry Lambert X-Mailer: Mozilla 4.7 [en]C-CCK-MCD {Sony} (Win98; U) X-Accept-Language: en MIME-Version: 1.0 To: Dan Ellard Cc: hackers@freebsd.org Subject: Re: FreeBSD NFS server benchmarks vs. OpenBSD, NetBSD?

I don't think anyone has benchmarked this; if they had, color me astonished. Your best bet would be to compare them yourself, since it's not that hard to install them. FWIW, You can't seperate server and client performance. If you have two clients and two servers, the first client caches operation X, and the second client does not, and you have two servers, one where operation X is very fast, and reads are OK, and the other where operation X is very slow, but reads are slightly faster than just "OK", which one shows up as being better is going to depend in the client you use in the benchmarks. If you're asking about a server and not a client, then you would be better of asking about the particular client by name vs. each of the possible server choices. PS: Your answers are going to differ based on UDP vs. TCP and rsize/wsize. In particular, if you need to have an rsize/wsize larger than the MTU, make sure you are using TCP, not UDP, or you will be shooting yourself in the foot (most Linux clients wonder why when they use UDP, their nubers go to hell; that's why). -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Thu Jun 20 20:26:11 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from avocet.mail.pas.earthlink.net (avocet.mail.pas.earthlink.net [207.217.120.50]) by hub.freebsd.org (Postfix) with ESMTP id 3513537B40F; Thu, 20 Jun 2002 20:26:09 -0700 (PDT) Received: from pool0544.cvx21-bradley.dialup.earthlink.net ([209.179.194.34] helo=mindspring.com) by avocet.mail.pas.earthlink.net with esmtp (Exim 3.33 #2) id 17LF3m-00067x-00; Thu, 20 Jun 2002 20:26:07 -0700 Message-ID: <3D129CA8.EFADA4FF@mindspring.com> Date: Thu, 20 Jun 2002 20:25:28 -0700 From: Terry Lambert X-Mailer: Mozilla 4.7 [en]C-CCK-MCD {Sony} (Win98; U) X-Accept-Language: en MIME-Version: 1.0 To: Giorgos Keramidas Cc: hackers@FreeBSD.org Subject: Re: Limiting clients per source IP address (ftpd, inetd, etc.) References: <20020621000924.GA2178@hades.hell.gr> Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG Giorgos Keramidas wrote: > I've been thinking for quite some time to add per-client-IP limiting > to ftpd, and I had almost decided upon something like the following, > where each child of ftpd has two numbers associated with it.

Someone just did something similar for inetd (per IP per port). The more I think about this, and the fact that there is code growing to do basically the same thing in every program, the more I think that the code to do this needs to be centralized. I would prefer a divert to an administrative daemon approach, using ipfw rules and exisitng code. You could also do it in the kernel, or you could do it by adding a wrapper library for "accept" and "close", where the accounting on connections can be enforced. Putting this code into a seperate daemon, or even natd, makes a lot more sense to me than hacking up the kernel, or every network application ever written. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Thu Jun 20 20:34: 8 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from albatross.prod.itd.earthlink.net (albatross.mail.pas.earthlink.net [207.217.120.120]) by hub.freebsd.org (Postfix) with ESMTP id D72D637B404 for ; Thu, 20 Jun 2002 20:34:04 -0700 (PDT) Received: from pool0544.cvx21-bradley.dialup.earthlink.net ([209.179.194.34] helo=mindspring.com) by albatross.prod.itd.earthlink.net with esmtp (Exim 3.33 #2) id 17LFBI-0005aW-00; Thu, 20 Jun 2002 20:33:52 -0700 Message-ID: <3D129E79.A32431EB@mindspring.com> Date: Thu, 20 Jun 2002 20:33:13 -0700 From: Terry Lambert X-Mailer: Mozilla 4.7 [en]C-CCK-MCD {Sony} (Win98; U) X-Accept-Language: en MIME-Version: 1.0 To: Lamont Granquist Cc: Jason Andresen , "Brandon D.

You mean that it doesn't integrate well with the UNIX credentials system. THe issue here is that Cyrus needs to be able to hook create/delete actions on accounts, and UNIX fails to provide a means of doing this. I look at this as a UNIX deficiency. You can actually get around it by using "pw" and utilizing the script hooks it has. The easiest real fix for this would be to write a PAM module to cause the UNIX users to authenticate against the Cyrus database. > The cyradm program is extremely deficient. Not a big issue, I think.

When I looked at it last night, it appeared to be necessary, since if the fdcheckstd() test fails oldcred will be left pointing to the credential held by the process. On further review, I see that this assignment isn't necessary after all because of the code that calls crfree() just looks at the state of newcred. > I haven't taken a look at your patch.

Everywhere else, you can indicate an end of data Mozilla has an option to enable http pipelining as a performance option. I regularly used this, maybe I shouldn't?

With the new ipfw code that i have posted it should be trivial to extend the match mask to use real bitmasks (so you can limit per-subnet, per port ranges, etc etc.) BTW in terms of implementation efficiency: this limit thing uses the same hash table used by dynamic ipfw rules. There is currently an (arbitrary) limit of a total of 1000 dynamic entries in the table, but no reason not to raise it much higher if you have memory. cheers luigi To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Fri Jun 21 0:36:12 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from aaz.links.ru (aaz.links.ru [193.125.152.37]) by hub.freebsd.org (Postfix) with ESMTP id 45A5637B40E; Fri, 21 Jun 2002 00:36:04 -0700 (PDT) Received: (from babolo@localhost) by aaz.links.ru (8.9.3/8.9.3) id LAA16091; Fri, 21 Jun 2002 11:37:10 +0400 (MSD) Message-Id: <200206210737.LAA16091@aaz.links.ru> Subject: Re: multiple gateways In-Reply-To: <200206202329.17885.Peter.Blok@inter.NL.net> from "Peter J.

The exact same argument can be made for not upgrading the OS, which is a much larger endeavour and can potentially screw things up much worse.

Does it still use 4 outstanding connections to the server on the other end, or does it serialize all your picture download requests through a single pipe? If the latter, what is the measured latency between the end of one response and the beginning of another? Basically, this is going to boild down to how the web server on the back end is written, and what's between you and it, in the way of smart hardware. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Fri Jun 21 1: 3:29 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from birch.ripe.net (birch.ripe.net [193.0.1.96]) by hub.freebsd.org (Postfix) with ESMTP id 10E2D37B40B for ; Fri, 21 Jun 2002 01:03:01 -0700 (PDT) Received: from laptop.6bone.nl (penguin.ripe.net [193.0.1.232]) by birch.ripe.net (8.11.6/8.11.6) with SMTP id g5L81oA31922; Fri, 21 Jun 2002 10:01:50 +0200 Received: (nullmailer pid 99902 invoked by uid 1000); Fri, 21 Jun 2002 06:37:16 -0000 Date: Fri, 21 Jun 2002 08:37:15 +0200 From: Mark Santcroos To: Julian Elischer Cc: Brooks Davis , "David E.

You mean "new mailboxes". THat's an issue of a client program that you could run from procmail on a user's behalf, based on a credential correspondance. You have to establish that correspondance first. Actually, there are patches that let you auto-create mailboxes, but, like your "procmail" fix, they are subject to denial of service attacks from people who know the process is automatic. Probably if you have particular problems with Cyrus, you should take them up with the Cyrus mailing lists. This has really gotten away from the request for a recommendation of which IMAP server to run on a FreeBSD system. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Fri Jun 21 1:30:33 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from smtp.comcast.net (smtp.comcast.net [24.153.64.2]) by hub.freebsd.org (Postfix) with ESMTP id A9E3C37B40F for ; Fri, 21 Jun 2002 01:30:28 -0700 (PDT) Received: from dallben (pcp529856pcs.nash01.tn.comcast.net [68.52.131.181]) by mtaout02.icomcast.net (iPlanet Messaging Server 5.1 HotFix 0.8 (built May 13 2002)) with ESMTP id <0GY100980RF703@mtaout02.icomcast.net> for freebsd-hackers@FreeBSD.ORG; Fri, 21 Jun 2002 04:25:55 -0400 (EDT) Date: Fri, 21 Jun 2002 03:25:55 -0500 (CDT) From: "Brandon D.

That's a very valid point. I'm certainly not recommending that Frank upgrade his OS, but I must note that I trust ugprading the entire FreeBSD operating system to be a smoother operation than upgrading one single, solitary commercial closed source package. At least if I'm gonna go about installing a new world I /know/ what I'm getting myself into and that if my box gets screwed up: a) It's probably my fault. b) I can go reading the error messages and Makefiles and figure out what I botched. I have the source. However, I would ask Frank if there's a particular reason he needs to use Covalent Raven SSL. OpenSSL is free, works like gangbusters, and comes with FreeBSD. I have a feeling he'd be much happier with it if there's not some other reason he cannot move to it. Brandon D.

I would like some clarification with regard to the union filesystem and mount option. First - what is the difference in principle between mounting with the union option (mount -o union) and the union filesystem type (mount_union)? Second - is there a way to have more than two filesystems stacked in a union? So that all writes will go to the upper layer, and reads will go down the stack until a lookup succeeds? That is - a way other than the inelegant and probably sub-optimal way of attaching some filesystem over an already-union filesystem to create another one? Thank you, any help appreciated, -- Tom -- Tom Alsberg - certified insane, complete illiterate. e-mail: Homepage: http://www.cs.huji.ac.il/~alsbergt/ * An idea is not responsible for the people who believe in it.

I know. I missed that post (probably deleted it accidentally), and a friend told me that this was being discussed. Since I had been giving the topic a big of thought, I thought I'd post what I had and ask for comments. The friend who notified me about this mentioned that a linear list was being used and what I had so far would probably be OK for inetd too. > The more I think about this, and the fact that there is code growing > to do basically the same thing in every program, the more I think > that the code to do this needs to be centralized. A simple core reuse of ../../foo.c would probably be sufficient in this case, since the part that does the limiting only needs the following interface: find_client_addr(); find_client_pid(); add_client(addr, pid); del_client(pid); /* called by reapchild() */ > Putting this code into a seperate daemon, or even natd, makes a > lot more sense to me than hacking up the kernel, or every network > application ever written.

The main reason I was looking for a userland implementation of this was that adding limiting to an FTP server that has an active number of a few thousand connections might be a little resource intensive to the kernel of the machine. It's probably OK to stay a bit to much within a userland function that searches a hash/list of addresses, but doing this in the kernel, is something I can't say I fully understand yet. I'm not familiar with the ipfw code. Would it be possible to limit the connections based on source address for a machine that has a few thousand connections and still not put a heavy load on the kernel? - Giorgos To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Fri Jun 21 6:41:15 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from iguana.icir.org (iguana.icir.org [192.150.187.36]) by hub.freebsd.org (Postfix) with ESMTP id A1C8C37B40A; Fri, 21 Jun 2002 06:41:11 -0700 (PDT) Received: (from rizzo@localhost) by iguana.icir.org (8.11.6/8.11.3) id g5LDfAt79866; Fri, 21 Jun 2002 06:41:10 -0700 (PDT) (envelope-from rizzo) Date: Fri, 21 Jun 2002 06:41:10 -0700 From: Luigi Rizzo To: Giorgos Keramidas Cc: Terry Lambert , hackers@FreeBSD.org Subject: Re: Limiting clients per source IP address (ftpd, inetd, etc.) Message-ID: <20020621064110.A79754@iguana.icir.org> References: <20020621000924.GA2178@hades.hell.gr> <3D129CA8.EFADA4FF@mindspring.com> <20020620222032.A73450@iguana.icir.org> <3D12CE82.C6761D96@mindspring.com> <20020621003518.A77089@iguana.icir.org> <20020621133626.GC2476@hades.hell.gr> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.2.5.1i In-Reply-To: <20020621133626.GC2476@hades.hell.gr>; from keramida@FreeBSD.org on Fri, Jun 21, 2002 at 04:36:26PM +0300 Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG On Fri, Jun 21, 2002 at 04:36:26PM +0300, Giorgos Keramidas wrote: ... > > BTW in terms of implementation efficiency: this limit thing > > uses the same hash table used by dynamic ipfw rules. > > There is currently an (arbitrary) limit of a total of 1000 > > dynamic entries in the table, but no reason not to raise it > > much higher if you have memory. > > The main reason I was looking for a userland implementation of this > was that adding limiting to an FTP server that has an active number of > a few thousand connections might be a little resource intensive to the > kernel of the machine.

Not only this. For example take the normal inetd behaviour for an FTP server. If the ftpd child processes grow above the limit, inetd simply won't spawn others. The users think that the service is dying (because it can be pinged, but the client can't log on) and begin to flame the operator (such a lame service :). Imagine this with the per IP address limit (this will hit more users, because of proxies, NAT boxes, etc). I think it is much better if the daemon can report this via a simple text message. The user limit thing is the last which is necessary to the FreeBSD ftpd for running an anonymous server. --------[ Free Software ISOs - ftp://ftp.fsn.hu/pub/CDROM-Images/ ]------- Attila Nagy e-mail: Attila.Nagy@fsn.hu Free Software Network (FSN.HU) phone @work: +361 210 1415 (194) cell.: +3630 306 6758 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Fri Jun 21 6:59: 2 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from lab.simerson.net (lab.simerson.net [64.224.9.172]) by hub.freebsd.org (Postfix) with ESMTP id 0E9BC37B403 for ; Fri, 21 Jun 2002 06:58:35 -0700 (PDT) Received: (qmail 83904 invoked from network); 21 Jun 2002 13:58:34 -0000 Received: from unknown (HELO matt-g4.interland.net) (63.96.155.254) by lab.simerson.net with DES-CBC3-SHA encrypted SMTP; 21 Jun 2002 13:58:34 -0000 Date: Fri, 21 Jun 2002 09:57:55 -0400 Subject: Re: FreeBSD NFS server benchmarks vs. OpenBSD, NetBSD?

Two years ago I did a bunch of extensive testing between three NFS servers (Sun, FreeBSD, NetApp) and one set of NFS clients (FreeBSD). Anyone that knows NFS really well would have predicted our test results that demonstrated the FreeBSD NFS server as being the best performer. The FreeBSD system was a "home build" with a GigE card, tuned MTU, large window, etc... running on a Cisco GigE switch. It solidly outperformed every other NFS server. If you were to have used Solaris clients, it's quite likely that one of the other two servers would have outperformed the FreeBSD server. Tuning the NFS server and the clients also has enormous potential for improvement. It took dozens of iterations to find the ideal combination of MTU size, nfsiod clients, nfsd servers, in the mail cluster I build. However, the engineering effort held large dividends. That mail system is still in use, seldom touched by human hands. It's withstood mail storms, DoS attacks, and many other network events that have been catastrophic to some of our other mail systems. Your best bet is to take a look at each of the platforms and determine which suits your needs best. Once you've etched that in stone, install your OS of choice and start tuning it to best suit your environment. The above is all unbiased. I personally have used quite a few NFS systems, a few more than I'd like to have. Many others will have opinions but here are mine: BSDI has, IMHO, one of the finest NFS implementations anywhere. I've used it extensively with NT, Mac OS, Mac OS X, BSDI, FreeBSD, Linux, and Solaris clients. As of BSDI 4.0/4.1 (IIRC) it supported NFS locking and worked VERY, VERY well with BSDI clients (as should be expected). I don't know how it's doing these days, I've dropped off the BSDI mailing lists and stopped using it in favor of FreeBSD. FreeBSD has very solid NFS code in addition to being a very robust, versatile, and downright fun operating system. It's very easy to do everything I want to with FreeBSD. It's NFS is missing locking support but it's very fast and works very well with FreeBSD and Mac OS X clients. I haven't used it with anything else. OpenBSD and NetBSD both fall into the same category in my book. Both OS's attack a niche that is too narrow for my purposes. I've installed NetBSD on a HP 9000, Mac IIci, and Intel hardware and, it works, but I couldn't ever easily do anything useful with them. OpenBSD is OpenBSD and life is too short to fight some battles. Sun wrote the book on NFS. They also missed the boat. NFS on Sun is reliable and works well with Sun NFS clients. Good luck with anything else. Performance has never been a feature of Sun's NFS implementation so keep shopping if you care about it. Linux NFS sucks. Some will point out that it's made LOTs of progress. They should also note there's a long ways to go. Linux NFS interaction with NetApp, FreeBSD, and Sun NFS servers is very problematic and never achieves "good" performance.

Yep. Which is why the only times I've upgraded the kernel on my production boxes have been when there is a critical fix that I _had_ to install, usually a security fix. -- Frank Mayhar frank@exit.com http://www.exit.com/ Exit Consulting http://www.gpsclock.com/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Fri Jun 21 7:55:20 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from tinker.exit.com (tinker.exit.com [206.223.0.1]) by hub.freebsd.org (Postfix) with ESMTP id A371037B406 for ; Fri, 21 Jun 2002 07:55:13 -0700 (PDT) Received: from realtime.exit.com (realtime [206.223.0.5]) by tinker.exit.com (8.12.3/8.12.3) with ESMTP id g5LEt748071622; Fri, 21 Jun 2002 07:55:08 -0700 (PDT) (envelope-from frank@exit.com) Received: from realtime.exit.com (localhost [127.0.0.1]) by realtime.exit.com (8.12.3/8.12.2) with ESMTP id g5LEt7ac017413; Fri, 21 Jun 2002 07:55:07 -0700 (PDT) (envelope-from frank@realtime.exit.com) Received: (from frank@localhost) by realtime.exit.com (8.12.3/8.12.3/Submit) id g5LEt6H2017408; Fri, 21 Jun 2002 07:55:06 -0700 (PDT) From: Frank Mayhar Message-Id: <200206211455.g5LEt6H2017408@realtime.exit.com> Subject: Re: inuring FreeBSD to the apache bug without upgrading apache ?

As I mentioned, the two reasons are (1) it hasn't been broken (at least up to now) and (2) I haven't had time.

Cyrus is a royal PITA to convince to run on a machine that also has shells. For instance: in my case my local mail provider doesn't support IMAP (and their mailserver is quite a long way away from me and behind some rather laggy and slow pipes). I wanted to be able to run Sylpheed when I'm on the X console and pine when I'm remotely logged in. The only option (given that they use different mail formats) seemed to be to dump all of my mail into a local IMAP server (it's not a ton of mail either) so both programs could see it. While the uw-imap can do this with a bit of prodding (you have to change a variable in a dependancy to get it to no spew your imap directories all throughout your home directory), it works OK. I originally tried Cyrus IMAP (because it was supposedly better), but nearly pulled my head off trying to get all of the authentication/permission/configuration/login/etc issues worked out. I never actually did successfully create a subdirectory on the Cyrus server, and after poring over the tons of not-very-helpful docs, I eventually gave up and went to the uw solution. UW might not be the best technically, but I wasn't going to have to spend 6 weeks learning the intricacies of the permissions system on my IMAP server to get it working. -- \ |_ _|__ __|_ \ __| Jason Andresen jandrese@mitre.org |\/ | | | / _| Network and Distributed Systems Engineer _| _|___| _| _|_\___| Office: 703-883-7755 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Fri Jun 21 10:20:33 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from rwcrmhc52.attbi.com (rwcrmhc52.attbi.com [216.148.227.88]) by hub.freebsd.org (Postfix) with ESMTP id DC9BB37B40D for ; Fri, 21 Jun 2002 10:20:15 -0700 (PDT) Received: from InterJet.elischer.org ([12.232.206.8]) by rwcrmhc52.attbi.com (InterMail vM.4.01.03.27 201-229-121-127-20010626) with ESMTP id <20020621172015.VMHY2751.rwcrmhc52.attbi.com@InterJet.elischer.org>; Fri, 21 Jun 2002 17:20:15 +0000 Received: from localhost (localhost.elischer.org [127.0.0.1]) by InterJet.elischer.org (8.9.1a/8.9.1) with ESMTP id KAA37091; Fri, 21 Jun 2002 10:04:01 -0700 (PDT) Date: Fri, 21 Jun 2002 10:03:59 -0700 (PDT) From: Julian Elischer To: Terry Lambert Cc: Aram Compeau , "David E.

Cyrus will by default use the system password database for its authentication, all that is left is to write up a script to your liking to manage the IMAP folders (I wrote one in PERL using the IMAP::Admin and Mail::IMAPClient modules, but please don't ask me for them, I'm not that proud of them :-). You can hook that script in to whatever you're using to create the system user accounts. In the near future, however, I plan to move the authentication database into LDAP and have Cyrus use that so that I can get rid of all of the local system accounts which are there for nothing other than authentication (the shells are just /sbin/nologin). All in all, I love the Cyrus design, and it hasn't given me a bit of trouble in over 6 years.

Maybe they all went to work for Quantum. :-) We have some Quantum SNAP Servers which are exactly the same thing as the older MaxAttach boxes except with bigger IDE drives, and they're still running the custom version of FreeBSD on them.

Attila Nagy makes a similar point. I think maybe the place for such a message is in a proxy server. The problem here is the point is to limit the number of connections by one IP address. The obvious reason for this constraint is to prevent a trivial denial of service attack occurring from a single IP address, so that clients from other IP address can get in. If you allow the connection to go through so that you can present a user with a capacity limitation message, then you are in much deeper trouble. You've already allowed your attacker to consume a connection resource, and enough of the protocol state engine has to be there for the inital connection negotiation, such that a failure message can be delivered down the protocol encapsulated channel (in the FTP case, the command channel, as a greetings message failure). After that happens, then you close the connection to the client. However, an attacking client can delay the handshake negotiation mechanism, thus consuming the per connection state information without a full connection. Alternately, for other protocols, immediately upon being connected to the server which is about to reject the connection, the client can wait for the server to do the connection close as part of the reject. This sends the socket into TIME-WAIT on the server, tying up the server resources for a full 2MSL. I think that permitting the connection to go through so that you can have a protocol rejection followed by a protocol close defeats much of the purpose of rate limiting based on IPs. If the patch were simply to set an overall connection limit, then it might make sense to allow the connection. Even so, you are then subject to attack. The ftp.cdrom.com server does a connection rejection based on protocol negotiation and a failure handshake message ("Too many users; maximum of 5000" or whatever). Technically, you could DOS attack this server: it's relying on pool retention in order to not run out of connections. In other words, it's assuming that the people connecting to it are legitimate. So a connection followed by a protocol rejection is for people who are playing nice. A connection reject outright is for people who are attacking you. In other words, it's a circuit breaker, not door security. Someone made the comment about people sitting behind a NAT, so that the number of connections from a given IP is actually legitimate traffic. This rate limitation is targetted at an attacker. One would expect that the number of connections would be set high enough that it would not trigger for these people, and low enough to catch an attacker. Really, if you get to this point in dropping connections, you are pretty much screwed anyway. It's not going to protect you from partial connection attempts, which are one of the most common attach types these days (e.g. SYN-flooding), since by the time you get through the protocol state machine, the resources that you should be worrying about protecting have already been compromised. If the idea is to prevent an attack, then you should not even queue the SYN requests from an IP after you hit the connection limit -- you should drop them. The network card DMA'ing them into memory in the first place is where you want to squelch the problem. That's probably a firmware issue, where you give the card a list of "squelch" IP addresses, and it ignores packets from there for . In any case, there's really little justification for accepting a connection and then immediately rejecting it with a protocol reject, since all of your overhead for protocol state, connection, etc., has already been consumed, if your intent is to guard against an attack. So I guess what needs to happen is a strict definition of what it is people expect to actually accomplish with this class of patches. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Fri Jun 21 15:34:57 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from hotmail.com (law2-f67.hotmail.com [216.32.181.67]) by hub.freebsd.org (Postfix) with ESMTP id CAF8F37B410 for ; Fri, 21 Jun 2002 15:34:46 -0700 (PDT) Received: from mail pickup service by hotmail.com with Microsoft SMTPSVC; Fri, 21 Jun 2002 15:34:46 -0700 Received: from 24.196.232.182 by lw2fd.hotmail.msn.com with HTTP; Fri, 21 Jun 2002 22:34:46 GMT X-Originating-IP: [24.196.232.182] From: "Kenneth Mays" To: freebsd-hackers@FreeBSD.ORG Subject: Re: FreeBSD on a MaxAttach?

I have been using pipelining in Mozilla for many months now without encountering a single, solitary server which caused me problems. I would guage that the number of servers out there which exhibit this problem is few. Netcraft could probably provide some fairly authoritative data in this regard, provided someone has a list of known buggy HTTP 1.1 implementations. It would probably be a much appreciated public service to the network if someone were resourceful enough to construct such a list, run it through netcraft, inform the admins of any and all known websites running buggy HTTP 1.1 implementations of the issue and recommend an upgrade path based on their currently installed HTTP server. This would be fairly simple to automate I would imagine with some help from the folks at netcraft. Brandon D.

What a clever hack! I don't know if I should revise my argument to include per-IP-per-file, which would of necessity be user space, or just admire it and say they *deserve* more bandwidth for being smart... I guess I'll argue that it's a different problem space, and limiting the number of connections for that reason is really easy to get around: 1) Open as many connections as you can 2) Divide the download between the connections In other words, your workaround only works if you take the file into account, or if you set your per IP connection limit to "1 connection per IP". The former is a totally different problem, while the latter can be done with ipfw or one of the other approaches already discussed. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Fri Jun 21 17:11:45 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from spork.pantherdragon.org (spork.pantherdragon.org [206.29.168.146]) by hub.freebsd.org (Postfix) with ESMTP id 85A2D37B403 for ; Fri, 21 Jun 2002 17:11:42 -0700 (PDT) Received: from spark.techno.pagans (spark.techno.pagans [4.61.202.145]) by spork.pantherdragon.org (Postfix) with ESMTP id 3D911471DA; Fri, 21 Jun 2002 17:11:41 -0700 (PDT) Received: from pantherdragon.org (speck.techno.pagans [172.21.42.2]) by spark.techno.pagans (Postfix) with ESMTP id 564A5FDA0; Fri, 21 Jun 2002 17:11:33 -0700 (PDT) Message-ID: <3D13C0B5.5A72DE0@pantherdragon.org> Date: Fri, 21 Jun 2002 17:11:33 -0700 From: Darren Pilgrim X-Mailer: Mozilla 4.76 [en] (Win98; U) X-Accept-Language: en MIME-Version: 1.0 To: Terry Lambert Cc: Chris Dillon , Lamont Granquist , Jason Andresen , "Brandon D.

There's no support for SSL in Cyrus? What about secure authentication? Speaking of which, what does it take to get secure authentication to work on FreeBSD? Courier supports it, but the port compiles with options to disable the secure authentication methods.

It depends on what you're trying to do. If all you want to do is mess with in-kernel TCP implementations then just hooking into the existing IP layer is sufficent.

Yes, but this is the case with any IMAP server and doesn't really have anything to do with Cyrus in particular. Unlike other IMAP servers, however, Cyrus supports SASL which offers plenty of non-plain-text authentication options, unfortunately none of which work with a local FreeBSD password database that I know of. There is always the option to use SSL, which is my preference, but unfortunately neither SSL nor SASL have widespread IMAP client support yet. -- Chris Dillon - cdillon(at)wolves.k12.mo.us - cdillon(at)inter-linc.net FreeBSD: The fastest and most stable server OS on the planet - Available for IA32 (Intel x86) and Alpha architectures - IA64, PowerPC, UltraSPARC, and ARM architectures under development - http://www.freebsd.org No trees were harmed in the composition of this message, although some electrons were mildly inconvenienced.

The only problem I have with the Quantum SNAP boxes is the total lack of being able to script any kind of setting of file ownerships or ACLs. You have to set those entirely through the web interface, which is entirely unacceptable when you want to do it for 2000 user home directories. The NT command-line ACL tools don't work, which is how I script that kind of thing on NT servers, and I've tried in vain to write a PERL script that actually accessed and parsed the web interface and sent back the appropriate POSTs. It almost works, but I gave up for the time being. The only other option would be to write something to run in the JVM that is on them, and I can't find any API documentation on setting file ownership or ACLs, not to mention I don't know Java well enough to write such a thing in the first place. :-) -- Chris Dillon - cdillon(at)wolves.k12.mo.us - cdillon(at)inter-linc.net FreeBSD: The fastest and most stable server OS on the planet - Available for IA32 (Intel x86) and Alpha architectures - IA64, PowerPC, UltraSPARC, and ARM architectures under development - http://www.freebsd.org No trees were harmed in the composition of this message, although some electrons were mildly inconvenienced.

SASL requires a shared secret, not a crypt(3) hash of a shared secret. That's why the passwords have to be stored plaintext on the mail server, and why, if you use the UNIX password database as the account database for Cyrus, you must pass the passwords over the wire in plaintext. Personally, I think SASL should have specified that you crypt(3) the passwords, and then use the resulting hash as the password value for the shared secret on both ends. At least that way, you would not have to pass cleartext to use the UNIX account database. This is a client problem. Or you could assign paswords to the client, so that the user sees the hashed value as their mail password, and the unhashed value as their shell account password. But in actuality, the issue is still a client issue (because clients don't hash shared secrets before using them in SASL exchanges). Pretty obvious, really. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Sat Jun 22 1:56: 5 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from utility.clubscholarship.com (utility.clubscholarship.com [198.78.70.175]) by hub.freebsd.org (Postfix) with ESMTP id 87F4737B40D for ; Sat, 22 Jun 2002 01:55:41 -0700 (PDT) Received: from localhost (root@localhost) by utility.clubscholarship.com (8.11.6/8.11.6) with ESMTP id g5M8pko93933; Sat, 22 Jun 2002 01:52:06 -0700 (PDT) (envelope-from root@utility.clubscholarship.com) Date: Sat, 22 Jun 2002 01:51:46 -0700 (PDT) From: Patrick Thomas To: Nielsen Cc: Subject: Re: (jail) problem and a (possible) solution ?

This typically means some sort of deadlock has happened, if possible getting a crash dump (this is detailed in the handbook i think) would help. The reason why it seems like apps are responding is because the kernel is only processing interrupts, something has hung the scheduler or deadlocked the kernel somehow... FYI, the kernel is not running except when interrupted by a device. -Alfred To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Sat Jun 22 3:39:20 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from goose.mail.pas.earthlink.net (goose.mail.pas.earthlink.net [207.217.120.18]) by hub.freebsd.org (Postfix) with ESMTP id 8D28937B400 for ; Sat, 22 Jun 2002 03:39:11 -0700 (PDT) Received: from pool0038.cvx40-bradley.dialup.earthlink.net ([216.244.42.38] helo=mindspring.com) by goose.mail.pas.earthlink.net with esmtp (Exim 3.33 #2) id 17LiI4-0006XB-00; Sat, 22 Jun 2002 03:38:49 -0700 Message-ID: <3D145392.3B09B1D3@mindspring.com> Date: Sat, 22 Jun 2002 03:38:10 -0700 From: Terry Lambert X-Mailer: Mozilla 4.7 [en]C-CCK-MCD {Sony} (Win98; U) X-Accept-Language: en MIME-Version: 1.0 To: Patrick Thomas Cc: Nielsen , hackers@freebsd.org Subject: Re: (jail) problem and a (possible) solution ?

I've kept quiet so far because I'm not the "jail" expert; Poul actually wrote the jail code, and there was someone else who understood it enough to recently add multiple IP support. Given your symptoms, I can pretty much guess where the problem is, but not really how to fix it, other than trial-and-error, since I tend to run jails on a number of my machines, and make them do things they aren't supposed to do... Knowing what version of FreeBSD you are running would be helpful. That you can still ping indicates that both hardware interrupts and NETISR are running. That NETISR runs indicates that things are still calling "splx()", which means things are still calling "spl*()" and coming back from it. The fact that you can still connect to servers that have active listens posted, but that you get no data is also indicative that the NETISR is running, at least up to the accept. It would be interesting to attempt a large number of connections, to see if the connections stop being accepted after you've tried more times than you set in listen(3) as the queue depth for the number of sockets allowed to sit there pending accept. If this happens (connection attempts start hanging, rather than being accepted), you know for certain that the process you are trying to talk to is not being scheduled to run. Basically, this implies one of two things is happening: 1) Your scheduler "lost" its head entry, so it's not scheduling anything to run, OR 2) You've used up all your resources on the machine (usually memory), and all of your processes are hung on a copy-on-write or allocate request, pending being serviced by the kernel If you can, compile the kernel for the box with the kernel debugger enabled, and "break to debugger" enabled, and break to the debugger on the console. The type "ps" and see what you get back as the wait channel everything you are trying to connect to is waiting on. This should be very informative, and it should be easy to locate the problem from there. If you have to, you can look at the scheduler queues, if there is anything in runnable state, and find out what's not there. Probably, it's not enough RAM, and your tuning parameters are set such that this isn't fatal to processes, when it should be. That you are able to ping, etc. guaranteed that you are not out of mbufs, and that you can connect that you aren't out of inpcb's or tcpcb's -- but mbufs are freelisted, so that's to be expected there (may not need more) and the pcb's are allocated at boot time (so are sockets, based on maxfiles), so tuning any of them after boot can get you in trouble. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Sat Jun 22 4:10:37 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from utility.clubscholarship.com (utility.clubscholarship.com [198.78.70.175]) by hub.freebsd.org (Postfix) with ESMTP id E503537B400 for ; Sat, 22 Jun 2002 04:10:29 -0700 (PDT) Received: from localhost (root@localhost) by utility.clubscholarship.com (8.11.6/8.11.6) with ESMTP id g5MB6SB04924; Sat, 22 Jun 2002 04:06:38 -0700 (PDT) (envelope-from root@utility.clubscholarship.com) Date: Sat, 22 Jun 2002 04:06:27 -0700 (PDT) From: Patrick Thomas To: Terry Lambert Cc: Nielsen , Subject: Re: (jail) problem and a (possible) solution ?

OK, there's memory, and then there's memory. The amount of swap you have, the fact that it's 4.5, and the amount of RAM you have imply to me that the problem is that you are out of pmap entries. You should up your KVA space to 2G or maybe even 3G; the default in 4.5 was 1G. Basically, I now think that you don't have enough memory to map how much memory and virtual memory you have. Amusingly enough, you might actually have *better* luck with a lot less swap... If your KVA space is already enlarged above the default, then you can ignore this and just go ahead with the debugging to see what the wait channels for all the processes that won't run are stuck at. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Sat Jun 22 5:36:30 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from infinitive.futureperfectcorporation.com (infinitive.futureperfectcorporation.com [196.25.137.68]) by hub.freebsd.org (Postfix) with SMTP id 3B54A37B400 for ; Sat, 22 Jun 2002 05:36:25 -0700 (PDT) Received: (qmail 58423 invoked by uid 0); 22 Jun 2002 12:36:17 -0000 Received: from gerund.futureperfectcorporation.com (196.25.137.65) by infinitive.futureperfectcorporation.com with SMTP; 22 Jun 2002 12:36:17 -0000 Received: (qmail 34033 invoked by uid 1001); 22 Jun 2002 12:36:44 -0000 Date: Sat, 22 Jun 2002 14:36:44 +0200 From: Neil Blakey-Milner To: Chris Dillon Cc: Terry Lambert , Lamont Granquist , Jason Andresen , "Brandon D.

But come to think of this I've seen it on other (4.5, patched pretty much to date) machines I use exclusively as routers. These have no jails on them. In these cases after uptimes of let's say 2 or 3 months, the machine's daemons stop responding and although a socket can be opened (just barely) it closes again when the process listening on the other side doesn't pick it up. IPSEC, firewalls, kernel routing, and all that continue to function just fine. Like you said it's just the userland stuff that has problems. The strange thing is, on one of my machines I was (eventually) able to log in from the console, take the system down to single user mode and back up and then everything worked like a charm.

Hi Lucky-- An excellent idea. A few thoughts for you: 1. You could peruse recent release notes (at least for i386) to get started. What little I know about the CPU-related options is encapsulated there, so thirty minutes on the phone with me is not likely to be useful, BTW. :-p 2. The CPU options in LINT are both version- and architecture-dependent. This fact probably makes this information a good candidate for the architecture-dependent hardware notes in the release documentation, with a pointer from the Handbook. 3. If you want a review on markup (or you want someone to mark up text for you), freebsd-doc@ is a great place to send things for feedback. Good luck, and thanks for volunteering to document this stuff!

To make explaining the cpu options worthwhile, you must show that only specifying I686 is sufficiently more optimal than specifying I686/I586/I486/I386.

I think he's referring to the flotilla of CPU feature options, mainly aimed at AMD and old Cyrix processors. A while back I went through all the places the I?86_CPU defines were used and determined that the only option that degraded performace when added to a kernel that didn't need it was I386_CPU; due to the 386's lack of locking primitives. For 486 and higher chips it doesn't matter if you have all three I[456]86_CPU defined or just the one you need. Most of the code activated by the options are specialized bcopy routines accessed through an indirect pointer, or initialization code used only once during bootup. -- Dan Nelson dnelson@allantgroup.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Sat Jun 22 11:14:45 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from apollo.backplane.com (apollo.backplane.com [216.240.41.2]) by hub.freebsd.org (Postfix) with ESMTP id 9C61137B400 for ; Sat, 22 Jun 2002 11:14:42 -0700 (PDT) Received: from apollo.backplane.com (localhost [127.0.0.1]) by apollo.backplane.com (8.12.3/8.12.3) with ESMTP id g5MIEgCV074082 for ; Sat, 22 Jun 2002 11:14:42 -0700 (PDT) (envelope-from dillon@apollo.backplane.com) Received: (from dillon@localhost) by apollo.backplane.com (8.12.3/8.12.3/Submit) id g5MIEggO074081; Sat, 22 Jun 2002 11:14:42 -0700 (PDT) (envelope-from dillon) Date: Sat, 22 Jun 2002 11:14:42 -0700 (PDT) From: Matthew Dillon Message-Id: <200206221814.g5MIEggO074081@apollo.backplane.com> To: hackers@freebsd.org Subject: Weird problems with BIND 8.3.1-REL Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG I am having weird problems with BIND.

[snip] I would argue that any effort put toward documenting this is better spent documenting something else. That particular "flotilla" of options relates entirely to a group of rather old, rather slow, and rather rare processors. The incidence of their use or necessity in the general FreeBSD user base is likely to be quite small. If you're running on asome ancient bastard child of Cyrix processor then chances are you're not running a performance critical application. At that level I say to anyone who tries to squeeze every last ounce of performance out of their CPU, "buy a faster CPU or UTFSL". Feel free to disagree and work on what interests you. Brandon D.

I understand this. Which is why you don't use NIS, or at least do not make it externally accessible. The exchange would have to include the salt, anyway, or the client couldn't crypt the value to the correct hash. The point is really to allow all the SASL methods to be used by a client, when all the server has is a UNIX password database.

Yeah, this is incredibly bogus. The proper way of handling this is SSL. It's very easy to man-in-the-middle a session that starts out unencrypted when a STARTTLS goes by for SMTP; it is just as easy for anything else that uses that rather bogus method. 8-(. -- TErry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Sat Jun 22 15:52:28 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from hawk.mail.pas.earthlink.net (hawk.mail.pas.earthlink.net [207.217.120.22]) by hub.freebsd.org (Postfix) with ESMTP id CEB8937B400 for ; Sat, 22 Jun 2002 15:52:24 -0700 (PDT) Received: from pool0523.cvx21-bradley.dialup.earthlink.net ([209.179.194.13] helo=mindspring.com) by hawk.mail.pas.earthlink.net with esmtp (Exim 3.33 #2) id 17Ltjn-0005Z4-00; Sat, 22 Jun 2002 15:52:12 -0700 Message-ID: <3D14FF75.9772644D@mindspring.com> Date: Sat, 22 Jun 2002 15:51:33 -0700 From: Terry Lambert X-Mailer: Mozilla 4.7 [en]C-CCK-MCD {Sony} (Win98; U) X-Accept-Language: en MIME-Version: 1.0 To: Patrick Thomas Cc: Nielsen , hackers@freebsd.org Subject: Re: (jail) problem and a (possible) solution ?

I've posted on how to do this before (should be in the archives). The pages are all going to be off-by-one from your calculations, for the recursive page mapping, or off-by-two if your kernel is an SMP kernel, for the per CPU page, so remember that, or you will end up with a kernel that simply doesn't boot. The easiest way is to look at the numbers in pmap.h, and figure out how they relate to 0xc0000000 (remember to OR in 0x00100000 after your math, to count the kernel loading at 1M). -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Sat Jun 22 16:52:38 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from utility.clubscholarship.com (utility.clubscholarship.com [198.78.70.175]) by hub.freebsd.org (Postfix) with ESMTP id F33EA37B400 for ; Sat, 22 Jun 2002 16:52:34 -0700 (PDT) Received: from localhost (root@localhost) by utility.clubscholarship.com (8.11.6/8.11.6) with ESMTP id g5MNmFl65645; Sat, 22 Jun 2002 16:48:35 -0700 (PDT) (envelope-from root@utility.clubscholarship.com) Date: Sat, 22 Jun 2002 16:48:15 -0700 (PDT) From: Patrick Thomas To: Terry Lambert Cc: Nielsen , Subject: Re: (jail) problem and a (possible) solution ?
