Created attachment 327346 [details] sys-apps:coreutils-8.20:20121024-200729.log.gz I've an unstable Gentoo image w/ glibc-2.16 and gcc-4.7.2 to play with user mode linux. Usually I do chroot into it to update it. Today I got during upgrade of coreutils a lot of lines like : ... >>> Jobs: 0 of 5 complete, 1 running Load avg: 5.67, 6.63, 5.99 (null)*(null) ../../sandbox-2.6/libsandbox/libsandbox.c:resolve_path():184: failure (Cannot allocate memory): (null)*(null) malloc(8192) (null)*(null) ../../sandbox-2.6/libsbutil/sb_write_fd.c:sb_copy_file_to_fd():22: failure (Cannot allocate memory): (null)*(null) malloc(4096) (null)*(null) ../../sandbox-2.6/libsbutil/sb_write_fd.c:sb_copy_file_to_fd():22: failure (Cannot allocate memory): (null)*(null) malloc(4096) ...

just noticed this after seeing thermal throttling messages in dmesg: $ sudo sensors radeon-pci-0100 Adapter: PCI adapter temp1: +64.0�C coretemp-isa-0000 Adapter: ISA adapter Core 0: +98.0�C (high = +82.0�C, crit = +100.0�C) Core 1: +95.0�C (high = +82.0�C, crit = +100.0�C) Core 2: +85.0�C (high = +82.0�C, crit = +100.0�C) Core 3: +81.0�C (high = +82.0�C, crit = +100.0�C) -- Holy smokes! So the above-mentioned results should be taken with a grain of salt until I figure out what has gone wrong with my thermal dissipation (in the meantime, I'm piling frozen veggies into my rack while I wait for some builds to finish :) )
(In reply to comment #0) how much memory have you given to your user mode linux ? gnulib (which coreutils includes) has a particular test that likes to see what the limits of getcwd() are and that can involve doing an extremely deep `while mkdir x && cd x; do :; done` test ...
Created attachment 331340 [details] chroot into an uml image (In reply to comment #5) > (In reply to comment #0) > > how much memory have you given to your user mode linux ? gnulib (which > coreutils includes) has a particular test that likes to see what the limits > of getcwd() are and that can involve doing an extremely deep `while mkdir x > && cd x; do :; done` test ... I did not started that image, I just chrooted into it to using the attached script (b/c due to the performance impact I emerge all package in a chrooted way rather than starting the image and then running emerge). Therefore I typical call is : $> sudo ~/workspace/bin/chr_uml.sh -r /home/tfoerste/virtual/uml/n22stab4 n22 ~ # eix-update -q && emerge --update @world --deep --newuse --changed-use --with-bdeps=y --verbose n22 ~ exit $> My system (stable Gentoo) has 8 GB RAM FWIW.
(In reply to comment #6) ok, a simple chroot shouldn't be a problem does the error show up when using sandbox-2.5 ? 2.6 has a bug where it always writes the output to /dev/tty so it's hard to trace back where the error is coming from.
(In reply to comment #7) > does the error show up when using sandbox-2.5 ? 2.6 has a bug where it well -it is fully unstable, so theres sanbox-2.6 : n22 ~ # eix -I sandbox [I] sys-apps/sandbox Available versions: 1.6-r2 2.3-r1 2.4 2.5 (~)2.6 {multilib} Installed versions: 2.6(06:22:12 PM 08/04/2012)(-multilib) Homepage: http://www.gentoo.org/ Description: sandbox'd LD_PRELOAD hack

HHm, an "ebuild ... test" doesn't gave those message, so the issue is probably related to sandbox itself. Therefore I tried to emerge that package w/o sandbox but this doesn't work (any longer ?) : $ cat /etc/portage/env/nosandbox FEATURES="-nosandbox" $ grep sandbox /etc/portage/package.env/misc sys-apps/coreutils nosandbox
(In reply to comment #10) > $ cat /etc/portage/env/nosandbox > FEATURES="-nosandbox" ick - double-negate pitfall ok with FEATURES="-sandbox" I do not see those message (of course the test case fails too).
dare i ask ... is this because of your ulimit setting (bug 445636) ?
(In reply to comment #12) > dare i ask ... is this because of your ulimit setting (bug 445636) ? ofc - issue still exists with "ulimit -s 65535"
(In reply to comment #13) i think you underestimate what gnulib in coreutils does to sandbox. set your stack to unlimited and try again.
(In reply to comment #14) > set your stack to unlimited and try again. ok : # ulimit -s unlimited # ulimit -s unlimited issue still happens

I'm also seeing this on a standard setup.
it's pretty easy to reproduce: $ sandbox $ ulimit -v 20 $ ls <lots of failures> can people who see these failures post `ulimit -a` ? i'm assuming this is just the ulimit settings in coreutils itself causing troubles rather than people setting low limits in their normal environment.

i don't think there's much to expect/do here w/sandbox. we can just patch the coreutils tests to use a higher ulimit when they run.
So can we get something in? This still fails with coreutils-8.27 unless ulimit -s is increased manually first. Test failures in core software is rather worrysome
(In reply to Mart Raudsepp from comment #24) if you're setting the stack low and it happens to crash coreutils tests doesn't make it a coreutils problem. it just happens to hit there. i don't think this is something coreutils should be dealing with, or even sandbox for that matter. looking closer at the tests, the sandbox malloc warnings don't break things. they come from the dynamic ulimit testing in the coreutils code where it tries to find a safe lower -v bound (init.cfg:get_min_ulimit_v_). sandbox spews OOM errors there. once coreutils finds a bound that is safe, it runs the actual test, and sandbox doesn't complain anymore. at this point, we probably want to change sandbox to be less chatty. failures in accessing memory/paths are pretty unlikely anymore to be due to bad sandbox code.
