It is permissible to sleep while some interrupts are blocked; it is just not (in 4-stable) permissible to sleep in interrupt context. The PR that I sent a few days ago was an example of one such circumstance. Is it really the case that in6_addmulti() can be invoked in interrupt context, and if so, why? -GAWollman To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message From owner-freebsd-current Sun Jul 15 14:20: 9 2001 Delivered-To: freebsd-current@freebsd.org Received: from sax.sax.de (sax.sax.de [193.175.26.33]) by hub.freebsd.org (Postfix) with ESMTP id 3F1EE37B401 for ; Sun, 15 Jul 2001 14:20:02 -0700 (PDT) (envelope-from j@uriah.heep.sax.de) Received: (from uucp@localhost) by sax.sax.de (8.9.3/8.9.3) with UUCP id XAA25133; Sun, 15 Jul 2001 23:20:00 +0200 (CEST) Received: (from j@localhost) by uriah.heep.sax.de (8.11.4/8.11.4) id f6FLHdN23530; Sun, 15 Jul 2001 23:17:39 +0200 (MET DST) (envelope-from j) Date: Sun, 15 Jul 2001 23:17:39 +0200 (MET DST) Message-Id: <200107152117.f6FLHdN23530@uriah.heep.sax.de> Mime-Version: 1.0 X-Newsreader: knews 1.0b.1 Reply-To: joerg_wunsch@uriah.heep.sax.de (Joerg Wunsch) Organization: Private BSD site, Dresden X-Phone: +49-351-2012 669 X-PGP-Fingerprint: DC 47 E6 E4 FF A6 E9 8F 93 21 E0 7D F9 12 D6 4E References: <20010714133434.F14426-100000@bsduser.ca> <20010715111916.X88805-100000@bsduser.ca> <20010715105132.A71519@dragon.nuxi.com> From: j@uriah.heep.sax.de (Joerg Wunsch) Subject: Re: buildworld problem.

The PRs I could find in a quick search are kern/21155, kern/23448 and kern/27334. The most probable cause for this effect is a synchonisation between the load measurement and processes that periodically run for short amounts of time. The load average is based on samples of the number of running processes taken at exact 5-second intervals. If some other process regularly runs with a period that divides into 5 seconds, that process may always be seen as running even though it may only run for a tiny fraction of the available CPU time. A very likely candidate process is bufdaemon; it sleeps for 1 second at a time, so if it happens to get scheduled in the same tick as the load measurement and before the load measurement, it will always be seen as running. The patch below causes the samples of running processes to be somewhat randomised; instead of being taken every 5 seconds, the gap now varies in the range 4 to 6 seconds, so that synchronisation should no longer occur. Would there be any objections to my committing this? Two comments on the patch: - This patch removes the SSLEEP case in loadav(), because in the existing code, p->p_slptime has always just been incremented in schedcpu() so this case never made a difference. To keep the same load average behaviour when loadav() is called at different times, this case needs to be removed. - The load average calculation now has really nothing to do with the VM system, so it could be moved elsewhere. I've just left it in vm_meter.c because that's where it's always been.

When a new unicast address is configured, the configuring node must be join the solicited-node multicast group corresponding to the unicast address. Since the autoconfiguration procedure runs under an interrupt context, the joining routine also runs under the context. JINMEI, Tatuya Communication Platform Lab.

I've tested this so far with bc and gdb and it seems to indeed work as expected, though I've not yet done a full make world with the patches. I've tried not to spam any previous FreeBSD changes (which should probably be submitted back to NetBSD to keep us fully in sync), but I may have missed something and will check again later. I've CC'ed the FreeBSD people who have made most of the (few) changes to libedit on our side in case they have time to verify the diffs. Fetch the following file and unpack it in /usr/src; it will overwrite the contents of lib/libedit.

We could easily provide a libreadline port for ports to use, as long as libedit does everything that's needed for the in-tree users (are there any others apart from bc and gdb?) The only danger is if future versions of those grow the need to use other parts of the API which we don't implement. The upside is that both the FreeBSD and NetBSD communities would be facing the same problem, meaning greater developer power to implement new features. Personally, I think it's worth it to get rid of a GNU dependency in the base system, as well as reducing the overall amount of functional code duplication.

I don't think that libreadline replacement is good idea. Libreadline is moving target - every version adds new functions and renames old ones. I doubt that NetBSD people will follow libreadline closely. Moreover, I think some libreadline stuff is very libreadline specific and will be not implemened in any case. So libedit as libreadline replacement can be used only if you want to save some space on floppy for very simple libreadline application, but not in general case. -- Andrey A.

I want all use of the cpu number removed. It seems to be just to avoid alignment problems that shouldn't happen in practice (the save area should always be suitably aligned if it isn't already, and I think it is already). > static void > -fpusave(addr, oncpu) > +fpusave(addr) > union savefpu *addr; > - u_char oncpu; > { > static struct savexmm svxmm[MAXCPU]; > + u_char oncpu = PCPU_GET(cpuid); > > if (!cpu_fxsr) > fnsave(addr); Also, `struct savexmm' is not too large to put on the stack.

Well, it depends on how you think of it; if you think of it instead as a "minimal libreadline" which does enough to support the other readline consumers in the FreeBSD base OS, then it makes a lot more sense to replace, IMO. We can make a port of GNU libreadline to satisfy ports which need more. Referring to Section 1.3.2 (FreeBSD Project Goals), this move seems to be well in line with the charter of the project.

SIGCHLD is entirely irrelevant to `nohup', as the > slightest amount of effort on Terry's part would have made clear. This is the answer I was asking for: is SIGCHLD "special", and thus treated differently, or is this applicable to all signals? I would be alarmed, if we were to treat different signals differently, which it seems you are advising. The reason I mentioned "nohup" is that the behaviour you are specifying, if applied to SIGHUP as well as SIGCHLD, would break "nohup". So if "nohup" is intended to continue to function as it has historically, then this change appears pretty arbitrary; at the very least, it complicates the signals API domain specific knowledge required to use the thing, which is annoying, to say the least. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message From owner-freebsd-current Mon Jul 16 12: 1: 2 2001 Delivered-To: freebsd-current@freebsd.org Received: from obsecurity.dyndns.org (adsl-63-207-60-62.dsl.lsan03.pacbell.net [63.207.60.62]) by hub.freebsd.org (Postfix) with ESMTP id 4B58937B405 for ; Mon, 16 Jul 2001 12:00:59 -0700 (PDT) (envelope-from kris@obsecurity.org) Received: by obsecurity.dyndns.org (Postfix, from userid 1000) id 1B73D67BA5; Mon, 16 Jul 2001 12:00:57 -0700 (PDT) Date: Mon, 16 Jul 2001 12:00:55 -0700 From: Kris Kennaway To: Garrett Wollman Cc: Kris Kennaway , current@FreeBSD.ORG Subject: Re: libedit replacement for libreadline Message-ID: <20010716120054.A94139@xor.obsecurity.org> References: <20010716013127.A16058@xor.obsecurity.org> <20010716103351.A81876@walton.maths.tcd.ie> <20010716031932.A5930@xor.obsecurity.org> <200107161516.f6GFGCT34314@khavrinen.lcs.mit.edu> Mime-Version: 1.0 Content-Type: multipart/signed; micalg=pgp-md5; protocol="application/pgp-signature"; boundary="zYM0uCDKw75PZbzx" Content-Disposition: inline User-Agent: Mutt/1.2.5i In-Reply-To: <200107161516.f6GFGCT34314@khavrinen.lcs.mit.edu>; from wollman@khavrinen.lcs.mit.edu on Mon, Jul 16, 2001 at 11:16:12AM -0400 Sender: owner-freebsd-current@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG --zYM0uCDKw75PZbzx Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable On Mon, Jul 16, 2001 at 11:16:12AM -0400, Garrett Wollman wrote: > <= said: >=20 > > Personally, I think it's worth it to get rid of a GNU dependency in > > the base system, as well as reducing the overall amount of functional > > code duplication. >=20 > I don't, particularly since the two programs which use it are already > GNU software, so you haven't actually bought any additional freedom by > making such a change.

The vinum patch hilights the problem that the new "libreadline" (just a symlink to libedit) exposes new symbols which may conflict with an existing program. I'm not sure how to deal with this.

I doubt you or any k00l d00d kernel hak0rs will step away from kernel development. My attempts to find anyone that wants to help maintain these contrib bits (and have the skills) have turned up zilch. Sorry you feel I am holding the project to ransom. But dealing with a 3 month old cycle of breakages just isn't in the least bit fun or even mildly enjoyable. Of course you mentioned you gave your Alpha away, so I know you aren't even trying to run FreeBSD on multiple platforms. So maybe you should keep that in mind when seeing the frustration of those that do. -- -- David (obrien@FreeBSD.org) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message From owner-freebsd-current Mon Jul 16 19:41:28 2001 Delivered-To: freebsd-current@freebsd.org Received: from nagual.pp.ru (pobrecita.freebsd.ru [194.87.13.42]) by hub.freebsd.org (Postfix) with ESMTP id 688F237B41D; Mon, 16 Jul 2001 19:40:04 -0700 (PDT) (envelope-from ache@nagual.pp.ru) Received: (from ache@localhost) by nagual.pp.ru (8.11.4/8.11.4) id f6H2e1Q21564; Tue, 17 Jul 2001 06:40:01 +0400 (MSD) (envelope-from ache) Date: Tue, 17 Jul 2001 06:40:01 +0400 From: "Andrey A.

Prior version work fine, in Feb & Mar I get either "Kernel trap 9 with interrupts disabled" or I think the same thing with trap 26 (really not sure on that one). Next I took a brand new current from this evening and tried it - it still hangs, but a keypress on the keyboard pretty much always breaks it out of the hang and into a normal boot. Now, I finally got the equipment and time together to remote gdb the bad kernel and here's what I get: I set a breakpoint at cam_xpt.c::xpt_config() - this is where the "Waiting 15 seconds.." message is from and stepped down through it. I get through the first xpt_for_all_busses (xptconfigbuscountfunc,...) and then I hit the second one (~line 6749 of cam_xpt.c) I pass through several things, including the xptconfigfunc() and end up in subr_autoconf.c::run_interrupt_driven_config_hooks(). At the bottom of this function there is a tsleep that gets called - this is apparently where it hangs. If I hit a key on the keyboard it will continue on past this point and all seems to work fine from then on. This is my first time this deep into the kernel - can you suggest a further plan of attack? thanks! dave c here's the dmesg output for this system if this helps any: Copyright (c) 1992-2001 The FreeBSD Project.
