Basically this is in the linux kernel: This is what mmap does in linux... static inline unsigned long do_mmap(struct file *file, unsigned long addr= , =09unsigned long len, unsigned long prot, =09unsigned long flag, unsigned long offset) { =09unsigned long ret =3D -EINVAL; =09if ((offset + PAGE_ALIGN(len)) < offset) =09=09goto out; =09if (!(offset & ~PAGE_MASK)) =09=09ret =3D do_mmap_pgoff(file, addr, len, prot, flag, offset >> PAGE_S= HIFT); out: =09return ret; } This is what mmap2 does: andstatic inline long do_mmap2( =09unsigned long addr, unsigned long len, =09unsigned long prot, unsigned long flags, =09unsigned long fd, unsigned long pgoff) { =09int error =3D -EBADF; =09struct file * file =3D NULL; =09flags &=3D ~(MAP_EXECUTABLE | MAP_DENYWRITE); =09if (!(flags & MAP_ANONYMOUS)) { =09=09file =3D fget(fd); =09=09if (!file) =09=09=09goto out; =09} =09down_write(¤t->mm->mmap_sem); =09error =3D do_mmap_pgoff(file, addr, len, prot, flags, pgoff); =09up_write(¤t->mm->mmap_sem); =09if (file) =09=09fput(file); out: =09return error; } So what it looks like to me is that mmap2 expects an offset that's alread= y=20 page-aligned (I'm not sure if this is the right way to say it), where mma= p=20 doesn't. the FreeBSD code in the linuxulator basically just takes the off= set=20 that is passed in with the linux mmap, and uses that to call FreeBSD's mm= ap=20 (the kernel version, not the one called from userland). So basically I'm=20 kinda stuck as to what to do to implement linux's mmap2. The only thing I= can=20 think of is to implement a FreeBSD "mmap2" that basically assumes that th= e=20 offset passed in is already page aligned or whatever, and just uses it, a= nd=20 then have linux_mmap2() just call the FreeBSD mmap2(). Any ideas?

What is it? > > It used to be used by NIC drivers to add something like AUI beside MII > provided media, correct? It is _still_ used that way. See if_xl.c. There exists a 3c905B-Combo card which supports a 10/100 RJ-45 port, a 10Mbps-only BNC port and a 10Mbps only AUI port. Why did I concoct MEDIAINIT for this? Because each device can have only one ifmedia structure. When a driver uses miibus, the ifmedia struct is initialized by the underlying PHY driver, and that initialization does not happen until after we leave the MAC driver's attach routine. It's not a problem to add additional media types to the ifmedia struct later, but we need to have the PHY driver call back to the MAC driver to do this, which is why every PHY driver has a call to MIIBUS_MEDIAINIT() in its attach routine. If the parent MAC driver does not implement this method, nothing happens. But if it does implement this method, the parent can use it to do some extra ifmedia_add()s to tack on some extra media types. > But it looks like every PHY's driver thinks it must call MEDIAINIT in its > attach() routine. So, if there would be two PHY on MII (can this happen?), Yes, though it's rare, and not always useful. > then the method will be called twice, and some NIC drivers (tx, xl, dc, > maybe more) will not behave well. They work fine if the author of the MAC driver was smart enough to check for this in his mediainit method and just return immmediately if the auxilliary media types have already been ifmedia_add()ed. Right now, the only card that uses this feature is the 3c905B-Combo, and its hardware configuration does not permit the sort of edge condition you are fretting over. > Isn't it reasonable to stop all PHY drivers from calling MEDIAINIT, and > call it once per miibus instance in miibus_attach() or miibus_probe() > instead? No. We want the PHY driver to set up its media types in the ifmedia struct first, and then add our own after those, which means we have to wait until the end of the PHY's attach routine, and it's newbus that calls the attach routines, not the miibus code. If you have a card or hardware configuration which is actually causing the scenario you describe, then say so. Otherwise, keep your fingers out of this code. No user-servicable parts inside. Keep out of children.

The authors of above drivers do not. :) I bet they didn't know... And a quest: how will you know inside YOURMAC_miibus_mediainit() that this is the call from the *last* PHY?

You're rigth. This is the main point - there is no place which would be more appropriate to notify MAC driver about PHY attachement completion. Well.... But this isn't very nice... As long as MEDIAINIT method is called per every PHY, it should at least contain a PHY-identifying argument, i think... Yet mii_inst would be enough, even to solve the ``quest above''. This way somebody could do per-PHY tricks in MAC driver :) If you really need to spot the all-PHYs-atachment-completion-event, then you must await it from miibus device, i think. > If you have a card or hardware configuration which is actually > causing the scenario you describe, then say so. No, I don't. But who knows what NIC there can exist? > Otherwise, keep your fingers out of this code. No user-servicable parts > inside. Keep out of children.

I guess ctob does what I need it to. I think that's probably why it still wasn't working yet... I think it also has to be page aligned before you pass it in though, I have to look at linux's do_mmap_pgoff() (I think that's the right function name) to see if it's expecting an already page-aligned arg, or if it's aligning it before it uses it.

The name implies that do_mmap_pgoff() takes page-shift'ed args. An offset specified as a page-shift is page-aligned by definition. Eg, when you call ctob(pgoff) this turns out to be (pgoff << PAGE_SHIFT) bytes.

This is usually because fstat(2) fails on file descriptors that have been revoked. By the time that message is printed, the /dev/console descriptors that were inherited from /etc/rc etc would have been revoke(2)'ed by the getty on /dev/ttyv0 or ttyd0. cron also used to do this. It would end up with handles to the console that would get revoked, and sendmail would get upset when cron fired it up. I "fixed" that a while back in cron to ensure that it had valid handles. Have a look at lsof/fstat output for the revoked fd's, and you'll probably find some new ones now.

There are fd's there, but they got revoke(2)'ed by the getty on the console. fstat(2) returns EBADF on the revoked fd's and is impossible to tell the difference between a revoke'd fd and a non-existing fd.

I have ad0s1a which is "/" and ad2s1a which is mounted on /rootback, it's an exact copy of the "/" filesystem. I wanted to try one of the failure scenarios from the howto (http://www.freebsd.org/doc/en_US.ISO8859-1/articles/vinum/failures.html) so I shutdown the machine, unplugged the ad0 drive. The machine found the boot loader on ad2 and I have a prompt.. so far so good.. I do "boot -as" so that I can manually tell the kernel which root filesystem to mount. here is what I get: ad2: 95396MB [193821/16/63] at ata1-master UDMA66 Manual root filesystem specification: : Mount using filesystem eg. ufs:/dev/da0s1a ?

Any ideas? This is too much work. Basically, it just wants to bitch when the offset is not page aligned, and then call the old mmap if it doesn't bitch. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Mon Apr 22 16:35:50 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from your-mom.student.umd.edu (your-mom.student.umd.edu [129.2.247.58]) by hub.freebsd.org (Postfix) with ESMTP id 6FF5937BC9C for ; Mon, 22 Apr 2002 16:32:29 -0700 (PDT) Received: from localhost (philip@localhost) by your-mom.student.umd.edu (8.11.6/8.11.6) with ESMTP id g3MIamT61644; Mon, 22 Apr 2002 18:36:48 GMT (envelope-from philip@your-mom.student.umd.edu) Date: Mon, 22 Apr 2002 18:36:48 +0000 (GMT) From: Philip To: Marc Heckmann Cc: freebsd-hackers@FreeBSD.ORG Subject: Re: "boot -a" in 4.5-STABLE In-Reply-To: <20020422174455.GA8682@merconic.com> Message-ID: <20020422183440.R61615-100000@your-mom.student.umd.edu> MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII 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 You might try just booting it normally and letting it fail.

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 We at Apple are noticing a strange problem with newer versions of ssh (which has been upgraded to OpenSSH_3.1p1) and FreeBSD 4.5-STABLE's sshd. This problem did not occur with our older ssh, but it also does not occur with the newer version and *any* other OS other than FreeBSD, e.g. if you ssh to a Linux or Solaris or Mac OS X box, for that matter, you will not see this behavior. What behavior am I talking about? This: jhubbard@wafer-> ssh jkh@winston.freebsd.org otp-md5 114 wi7854 ext S/Key Password: otp-md5 117 wi5044 ext S/Key Password: otp-md5 397 wi0652 ext S/Key Password: jkh@winston.freebsd.org's password: The machine "wafer" is a Mac OS X box running 10.1.3 and winston.freebsd.org is running FreeBSD 4.5-STABLE. The authentication method which tries this S/Key stuff is "keyboard-interactive" and this is tried, for some reason, before the "password" auth method. If you compile sshd on the FreeBSD side without SKEY support built-in, the problem also goes away. My question: Who's "wrong" here, FreeBSD or Mac OS X? If the latter, why doesn't Linux or anything else produce this problem? I ask now because I know that the usage of Mac OS X is growing and there are going to be a lot of annoyed users (like me!) who very quickly get tired of having to wind through all the bogus S/Key password prompts before they can actually type in their real password (and no, skey is not enabled on winston and I have never done a keyinit operation, so I couldn't S/Key authenticate to it if I wanted to). - Jordan To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Mon Apr 22 17:46: 5 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from tao.org.uk (genius.tao.org.uk [212.135.162.51]) by hub.freebsd.org (Postfix) with ESMTP id 82DFB37B41A for ; Mon, 22 Apr 2002 17:45:57 -0700 (PDT) Received: by tao.org.uk (Postfix, from userid 100) id 82560602; Tue, 23 Apr 2002 01:45:04 +0100 (BST) Date: Tue, 23 Apr 2002 01:45:04 +0100 From: Josef Karthauser To: Jordan Hubbard Cc: hackers@freebsd.org Subject: Re: ssh + compiled-in SKEY support considered harmful?

This was discussed fairly extensively regarding -current: basically, s/key is "greedy" and attempts to fake s/key responses even for users who don't have s/key enabled. Nothing is wrong with challenge response -- arguably, that's a cleaner way to handle things as a default in the client, since it means if you connect to a server that does want to use challenge response, it DTRT. The fix in -CURRENT, I believe, was to make s/key "faking" for non-enabled users be an option, and to turn the option off by default. That fix relies on the extensive PAM updates in -CURRENT however; in -STABLE it can probably be similarly replicated via appropriate tweaking of sshd (?).

When the default behaviour is changed, the dicussion belongs here, since here is where the proplr who live who can change it back to The Way It Is Supposed To Be By Default(tm). IMO, you should have to: "Add ``ChallengeResponseAuthentication yes'' to get the new behaviour" NOT: "Add ``ChallengeResponseAuthentication no'' to get the historical behaviour" It's really damn annoying. Maybe the intention was to subtlely harass people who put passwords challenge/response pairs into shell scripts, but the effect has been to unsubtlely harass people who wire their typing of passwords into their medulla. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Mon Apr 22 19:53:11 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from winston.freebsd.org (adsl-64-173-15-98.dsl.sntc01.pacbell.net [64.173.15.98]) by hub.freebsd.org (Postfix) with ESMTP id 6050C37B417; Mon, 22 Apr 2002 19:53:07 -0700 (PDT) Received: from winston.freebsd.org (jkh@localhost [127.0.0.1]) by winston.freebsd.org (8.12.2/8.12.2) with ESMTP id g3N2r67W011671; Mon, 22 Apr 2002 19:53:06 -0700 (PDT) (envelope-from jkh@winston.freebsd.org) To: Robert Watson Cc: Oscar Bonilla , Anthony Schneider , Mike Meyer , hackers@FreeBSD.ORG Subject: Re: ssh + compiled-in SKEY support considered harmful?

The release notes at: http://www.FreeBSD.org/releases/4.5R/errata.html imply you can also fix this on the client side by adding the line: PreferredAuthentications publickey,password,keyboard-interactive to your own ~/.ssh/config file (useful if you need to connect to some machine where you can't change the /etc/ssh/sshd_config file).

I spent half a day recently trying to find why I could no longer open windows on my X display, only to discover that somebody had turned off tcp connections by default. I have a problem with this, and as you imply, so will a lot of other people. As a result of this sort of thing, people trying to migrate from other systems will probably just give up. I certainly would have. While it's a laudable aim to have a secure system, you have to be able to use it too. I'd suggest that we do the following: 1. Give the user the choice of these additional features at installation time. Recommend the procedures, but explain that you need to understand the differences. 2. Document these things very well. Both this ssh change and the X without TCP change are confusing. If three core team members were surprised, it's going to surprise the end user a whole lot more. We should at least have had a HEADS UP, and we probably need a security policy document with the distributions.

A "secure by default" policy is by far more favorable than a "not so secure by default, but we'll try to let you know how to make it more secure easily" policy. Consider a move to make telnetd commented out in inetd.conf a default. Many newcomers will of course be baffled, but it is in the long run a better policy, and people will get=20 used to it. =20 This example is somewhat of an *extremely* simplified analogy to adding s/key authentication as a default before password authentication, but it=20 still holds in that a default installation had better be more secure than= =20 not. If FreeBSD were to have installation dialogues with the user=20 suggesting that the user install certain components for security purposes,= =20 the user will likely opt for the default "button," which I assume in this= =20 case would default to have the less secure, more conventional option. =20 I think that #2 alone is the way to go. Make it "clear" (not that that=20 is necessarily an easy task) that the default install of a certain=20 software package no longer follows what has historically been the default,= =20 or at least do so in the case where the software will become unusable to=20 the unknowing user.

The SSH change happened before 4.5-RELEASE, but wasn't documented. I admit to having been totally unaware of this change at the time. green and I made several attempts at an item for the errata, which, while not perfect, does give some workarounds for the problem, including almost every one mentioned in this thread. So far, it looks like precious few people on this thread actually read it. :-( > We should at least have had a HEADS UP, Having run into the SSH change myself, I agree. I haven't bumped into the "X without TCP" change. > and we probably need a > security policy document with the distributions. Hmmm. Still trying to wrap my mind around this concept, but I'm worried that people won't read *that* document either. In any case, someone needs to maintain it to make sure it doesn't get stale.

It was added some time=20 around 2001/10/26 to the XFree86-4 megaport. When the metaport was=20 created, the patch was incorporated too.=20 A simple 'man startx' should have cleared your mind: Except for the '-listen_tcp' option, arguments immediately following the startx command are used to start a client in the same manner as xinit(1). The '-listen_tcp' option of startx enables the TCP/IP transport type which is needed for remote X displays. This is disabled by default for security reasons. > I have a problem with this, and as you imply, so will a lot of other > people.

I'd agree with option 2. Except that people trying to use X with tcp=20 connections probably won't look in the security policy document for a=20 solution.

Why should I have to read the man page to find changes? How do I know which man page to read? If I did that for everything that happened, I wouldn't get any work done.

I think it shouldn't happen at all unless people agree to it. > I do have to say you're the first one I see who complains about > this... Maybe the others have given up. But since we're on the subject, why? What's so insecure about X TCP connections? Until you explicitly allow connections, the only system that can open the server is the local system. -- See complete headers for address and phone numbers To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Tue Apr 23 2:14: 5 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from taupo.cs.waikato.ac.nz (taupo.cs.waikato.ac.nz [130.217.250.12]) by hub.freebsd.org (Postfix) with ESMTP id 7179137B419; Tue, 23 Apr 2002 02:14:01 -0700 (PDT) Received: (from joerg@localhost) by taupo.cs.waikato.ac.nz (8.11.3/8.11.1) id g3N9Dxh56699; Tue, 23 Apr 2002 21:13:59 +1200 (NZST) (envelope-from joerg) Date: Tue, 23 Apr 2002 21:13:59 +1200 From: Joerg Micheel To: "Greg 'groggy' Lehey" Cc: Jochem Kossen , hackers@freebsd.org Subject: Re: Security through obscurity?

I thought there was a policy of the least surprise, it might have been to kernel code, but should be applied here as well. The system has to work right away, when installed out of the box. Period.

Period. > No when's and if's. And don't tell me that X11 is an add-on and luxury. > We are living in the 21st century. There are people who will tell people that still use X11 tcp sockets to start living in the 21st century. ssh X11 forwarding still works, it's only the (often much lower security) tcp sockets that are disabled by default. (And if the "none" cipher is available, the overhead would be minimal for even the most underpowered machine.) At least Debian takes this stance, and so many believe it's a sane default. If it were reverted, I'm sure there'll be lots of people re-adding the change to their security regimen. And lots more people scurrying to patch when the next DoS or exploit comes out.

But if I am booting with "-a" and "-s", shouldn't the fstab just be ignored? I should have / on ad2s1a mounted RO at that point so I can manually re-mount RW and edit my fstab. The vinum bootstrap howto also seems to describe that way. What is the expected behavious should be when using the "-a" switch?

I may not understand all the issues here, but can the situation be helped by improving the reporting. I.e. if the firewalling prohibits access to the X11 TCP socket, why would the firewall not report this instantly at the first attempt to connect, to be visible at the console and in /var/log/messages.

Being scared by X11 access mechanisms, I always disabled the TCP listen of the X server, and I always used ssh with X forwarding. marco To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Tue Apr 23 3:26:41 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from scribble.fsn.hu (scribble.fsn.hu [193.224.40.95]) by hub.freebsd.org (Postfix) with SMTP id C4B0637B400 for ; Tue, 23 Apr 2002 03:26:37 -0700 (PDT) Received: (qmail 25034 invoked by uid 1000); 23 Apr 2002 10:29:03 -0000 Received: from localhost (sendmail-bs@127.0.0.1) by localhost with SMTP; 23 Apr 2002 10:29:03 -0000 Date: Tue, 23 Apr 2002 12:29:03 +0200 (CEST) From: Attila Nagy To: hackers@freebsd.org Subject: sendfile() in tftpd?

I agree with this point, in general. FreeBSD shouldn't be like OpenBSD, where everything is so secure by default that you can't get anything done. For example, most people who use X don't know---and don't want to know---how it works. If the defaults are too restrictive, they will be frustrated, and maybe they'll figure out how to make things unrestrictive without understanding what's going on. On the other hand, if the defaults are not cautious enough, the same people will need to apply patches when the next remotely exploitable hole in X is found, and many of them won't bother. I'm a bit more wary of third-party applications, particularly big ones like X, so disabling TCP connections by default seems like a reasonable thing to do. But it should have been documented in a place where people actually look when they upgrade.

I agree that X11 isn't very forward looking; it'd be nice if the displays were themselves CORBA objects, so you could embed desktops to use any display technology you wanted, so that you could build a desktop compute server for 1000 users without eating 11G of RAM to do it. Until someone writes that though... It's be nice if the ssh X11 forwarding were not the prefered method of remote access to X11. Particularly since I haven't seen any fixes for the MIT shared memory extension going in to stop the inevitable shared memory leaks by Netscape, etc., or anything else that uses it for bitmaps, and is long running, so the resources get used up and never reclaimed. Disabling the workaround -- which is to use network connections, instead of using the UNIX domain socket, thereby disabling the libraries use of the shared memory extension -- isn't my idea of a good approach. All it does is exacerbate the problem, for questionable security ("not listening" is not the same thing as having a firewall, so if TCP is vulnerable for X11, then it's vulnerable for every other port that *is* listening). Forget Debian, what does OpenBSD do? It's the gold standard when it comes to anal default settings. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message From owner-freebsd-hackers Tue Apr 23 3:53:46 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from gull.prod.itd.earthlink.net (gull.mail.pas.earthlink.net [207.217.120.84]) by hub.freebsd.org (Postfix) with ESMTP id 2B2F337B405 for ; Tue, 23 Apr 2002 03:53:42 -0700 (PDT) Received: from pool0061.cvx21-bradley.dialup.earthlink.net ([209.179.192.61] helo=mindspring.com) by gull.prod.itd.earthlink.net with esmtp (Exim 3.33 #2) id 16zxvX-0005Kd-00; Tue, 23 Apr 2002 03:53:40 -0700 Message-ID: <3CC53D18.577A9A67@mindspring.com> Date: Tue, 23 Apr 2002 03:53:12 -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: Attila Nagy Cc: hackers@freebsd.org Subject: Re: sendfile() in tftpd?

Well, since I have only complained, however loudly, on the irc channel, let me pipe in. It is inconvenient, to say the least, to have to exit X after over 40 shell sessions are open because you suddenly realize X just stopped opening the TCP port out of nothing after you last upgraded it. Or because you forgot to use the -listen_tcp option, not unusual since I never needed it before. An changing the script is not good enough either, since a portupgrade -a may change it back. Do you use remote X clients at all? Because I cannot conceive of a person who does and cannot understand how against POLA this change is. The -listen_tcp option is ridiculous to me. You must never *HAVE* to resort to a parameter for a thing which is not only the default but the the _only_ way you want it. The port *SHOULD* indicate that the listen port is no longer the default, and the *MUST* be a way of saying you want it always, either a port option so I can put it in make.conf, or an environment variable so I can put it in login.conf. But security is good. As a matter of fact, I'll change loader not to load a kernel by default, since this is a security hole in case the machine reboots.

That's the > same reason sendfile() is stupid for POP3, IMAP4, and SMTP servers... Hmm. Both FTP and TFTP supports ASCII and binary transfers, am I right? In libexec/ftpd this case is handled this way: case TYPE_A: while ((c = getc(instr)) != EOF) { [...] case TYPE_L: [...] while (err != -1 && filesize > 0) { err = sendfile(filefd, netfd, offset, 0, (struct sf_hdtr *) NULL, &cnt, 0); [...] As far as I can determine. In libexec/tftpd there is also a similar possibility to handle each case, because there is "netascii" and "octet". We have a lab here with machines, which have NICs with built-in bootrom (Intel PRO/100) and run bpbatch (http://www.bpbatch.org/). During the startup the user gets a nice menu from which he/she can choose the OS (various Windows versions for the education and Linux). After this the program checks the image on the harddisk and if it fails it gets from the network. And that's what isn't too good. One client can achieve about 15 Mbps but if more than 10 (usually 20-30) clients want to fetch the images the TFTP server first slows down (it eats all the CPU of the server, which is a fast AthlonXP 1600+) then times out. I think this could be improved if TFTP could use sendfile(). (I have a busy FTP server and I know how much sendfile() can speed up things) The main question here seems to be: could sendfile() be used with UDP, or it is just for TCP? BTW, the bpbatch stuff uses binary transfer (according to tcpdump output)... --------[ 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 Tue Apr 23 6:20:55 2002 Delivered-To: freebsd-hackers@freebsd.org Received: from scribble.fsn.hu (scribble.fsn.hu [193.224.40.95]) by hub.freebsd.org (Postfix) with SMTP id AEB3337B400 for ; Tue, 23 Apr 2002 06:20:49 -0700 (PDT) Received: (qmail 25908 invoked by uid 1000); 23 Apr 2002 13:23:16 -0000 Received: from localhost (sendmail-bs@127.0.0.1) by localhost with SMTP; 23 Apr 2002 13:23:16 -0000 Date: Tue, 23 Apr 2002 15:23:16 +0200 (CEST) From: Attila Nagy To: Tomas Svensson Cc: hackers@freebsd.org Subject: Re: sendfile() in tftpd?

I think it's implemented in FreeBSD's tftpd too. (I can get 750 MB images with TFTP easily). My impression about this stuff: compiled and started on an up-to-date FreeBSD STABLE BOX (AthlonXP 1600+, 512MB DDR, two Intel PRO/100 with FEC) The lab consists of 733 MHz Celerons with Intel PRO/100 and 128MB RAM. The switch is a HP4000M. With the FreeBSD tftpd I could only get around 40 Mbps out of this box, the CPU usage was 100%. One client could fetch the stuff with an average speed of 14-15 Mbps. I could stay at this speed with 4-5 machines, fetching the images, after this count the bandwidth usage decreased per machine. With Danny's tftpd I could get 16-17 Mbps with one machine (this is what the client says) and around 4 Mbps per client at a concurrency of 24 machines. That's about 90-96 Mbps. I will try do more benchmarks with an accurate method, once I could figure out what should I use to measure the outgoing traffic to specific IP addresses (a /24 subnet)... BTW, FreeBSD's tftpd doesn't drop connections once it built up, while there are some problems with Danny's implementation in this area, but I am sure that this will be solved very soon. --------[ 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 Tue Apr 23 7:55:22 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 8E4CB37B416; Tue, 23 Apr 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 g3NEtBcN078041; Tue, 23 Apr 2002 07:55:11 -0700 (PDT) (envelope-from frank@exit.com) Received: from realtime.exit.com (localhost [127.0.0.1]) by realtime.exit.com (8.12.2/8.12.2) with ESMTP id g3NEsxwn019647; Tue, 23 Apr 2002 07:54:59 -0700 (PDT) (envelope-from frank@realtime.exit.com) Received: (from frank@localhost) by realtime.exit.com (8.12.2/8.12.2/Submit) id g3NEsxFR019646; Tue, 23 Apr 2002 07:54:59 -0700 (PDT) From: Frank Mayhar Message-Id: <200204231454.g3NEsxFR019646@realtime.exit.com> Subject: Re: Security through obscurity?
