[2022-03-22T01:41:34Z] <dilyn> things in KISS Linux land are very mellow and chill. I think this whole community has found its maximal equilibrium
[2022-03-22T01:41:46Z] <dilyn> it's tight knit & gucci :v
[2022-03-22T01:52:34Z] <jslick> It has updated firefox and sgt-puzzles, two of the things that make a headed linux distribution.  It is indeed very mellow and chill.
[2022-03-22T01:53:25Z] <dilyn> honestly, what more could you want
[2022-03-22T03:22:51Z] <rohan> hi guys
[2022-03-22T03:24:04Z] <rohan> how i add alias permanently in my system?
[2022-03-22T03:25:47Z] <acheam> add it to your shell rc file
[2022-03-22T03:26:26Z] <acheam> You need to set one for busybox ash IIRC
[2022-03-22T03:26:40Z] <acheam> so put "ENV=~/.ashrc" in ~/.profile
[2022-03-22T03:26:50Z] <acheam> then your aliases in ~/.ashrc
[2022-03-22T03:27:58Z] <rohan> okay
[2022-03-22T03:28:21Z] <rohan> so .profile is not like a ashrc?
[2022-03-22T03:28:29Z] <rohan> all that time i used like it
[2022-03-22T03:34:05Z] <acheam> .profile is read by the login shell, and rc files are read by interactive shells
[2022-03-22T03:34:54Z] <acheam> so if you set an environment variable in .profile, you'll have to log out and in again to have it take effect systemwide

[2022-03-22T04:56:56Z] <GalaxyNova_> hi
[2022-03-22T09:33:54Z] <user86234> hi everyone
[2022-03-22T09:34:20Z] <user86234> i'm having some issues installing kiss linux
[2022-03-22T09:34:58Z] <user86234> when i run `cd /var/db/kiss/installed && kiss build *`
[2022-03-22T09:35:20Z] <user86234> i get this error `ERROR pigz Failed to download https://zlib.net/pigz/pigz-2.6.tar.gz`

[2022-03-22T09:39:06Z] <illiliti> xd
[2022-03-22T09:39:11Z] <testuser[m]> lol
[2022-03-22T09:46:00Z] <illiliti> i don't have spare space to create swap partition
[2022-03-22T09:46:05Z] <illiliti> and swap as pool on zfs is quite unstable
[2022-03-22T09:46:09Z] <illiliti> https://github.com/openzfs/zfs/issues/7734
[2022-03-22T09:47:43Z] <illiliti> i can create swap on usb stick, but ... that would be slow af
[2022-03-22T09:51:42Z] <testuser[m]> illiliti: check the linked merge request in that alpine issue
[2022-03-22T09:59:26Z] <testuser[m]> https://gitlab.alpinelinux.org/alpine/aports/-/merge_requests/32307
[2022-03-22T10:12:55Z] <illiliti> try in gdb: thread apply all backtrace
[2022-03-22T10:16:48Z] <testuser[m]> i got the bt

[2022-03-22T10:20:32Z] <illiliti> i think we have a bug that you previously mentioned: https://github.com/void-linux/void-packages/issues/29105#issuecomment-787219097
[2022-03-22T10:20:59Z] <illiliti> https://marc.info/?l=musl&m=161232508119452&w=2
[2022-03-22T10:34:18Z] <testuser[m]> https://marc.info/?l=musl&m=161238368314692&w=2 the thread mentions the test that times out aswell
[2022-03-22T10:35:20Z] <testuser[m]> illiliti: does --no-sandbox imply --single-process ?
[2022-03-22T10:38:07Z] <illiliti> i think --single-process implies --no-sandbox, not vice-versa
[2022-03-22T10:38:37Z] <illiliti> but i may be wrong
[2022-03-22T10:38:44Z] <illiliti> https://source.chromium.org/chromium/chromium/src/+/main:sandbox/linux/services/namespace_sandbox.cc;l=115?q=MaybeUpdateGlibc&sq=
[2022-03-22T10:40:20Z] <illiliti> we need this func for musl
[2022-03-22T10:43:32Z] <illiliti> https://source.chromium.org/chromium/chromium/src/+/main:sandbox/linux/services/namespace_sandbox.cc;l=225
[2022-03-22T10:44:01Z] <illiliti> ForkInNewPidNamespace uses this hack to update tid on clone()
[2022-03-22T10:46:12Z] <illiliti> the equivalent hack for musl should fix the bug i guess
[2022-03-22T10:47:58Z] <illiliti> we can also attempt to rewrite this func to use fork+setns instead of clone
[2022-03-22T10:48:35Z] <illiliti> theoretically, this should fix bug too
[2022-03-22T10:53:34Z] <illiliti> https://source.chromium.org/chromium/chromium/src/+/main:base/threading/platform_thread_posix.cc;l=213-227
[2022-03-22T10:53:54Z] <illiliti> interesting
[2022-03-22T10:57:59Z] <illiliti> testuser[m]: can you try to run tests in base/threading?
[2022-03-22T10:58:29Z] <testuser[m]> wait
[2022-03-22T11:20:13Z] <testuser[m]> illiliti: how do i build those lol idk the target name
[2022-03-22T11:21:35Z] <testuser[m]> o shit
[2022-03-22T11:21:45Z] <testuser[m]> its in base_unittests which is pretty fat
[2022-03-22T11:26:01Z] <testuser[m]> ninja: file is missing and not created by any action: '../../base/test/data/file_util/binary_file.bin'
[2022-03-22T11:26:05Z] <testuser[m]> idk where to get these test files from
[2022-03-22T11:26:56Z] <illiliti> hm
[2022-03-22T11:27:34Z] <testuser[m]> it asked for some ttf files for the sandbox tests too i just created empty files there lol
[2022-03-22T11:42:30Z] <phoebos> testuser[m]: libretls 3.5.1 has been released
[2022-03-22T11:51:06Z] <testuser[m]> phoebos: done
[2022-03-22T11:51:32Z] <phoebos> :)
[2022-03-22T11:51:33Z] <testuser[m]> illiliti: should i try disabling the MaybeUpdateGlibcTidCache call on my glibc build and see if the sandbox issue starts there?
[2022-03-22T11:51:42Z] <testuser[m]> then we can be sure that it's the one
[2022-03-22T11:52:05Z] <phoebos> interesting commit message :p
[2022-03-22T11:55:38Z] <illiliti> testuser[m]: good idea
[2022-03-22T12:30:45Z] <testuser[m]> illiliti: tabs do freeze like musl but no concrete crash
[2022-03-22T12:30:47Z] <testuser[m]> weird
[2022-03-22T12:33:46Z] <illiliti> tabs freezes on musl as well
[2022-03-22T12:33:57Z] <testuser[m]> yeah
[2022-03-22T12:34:00Z] <testuser[m]> but its not showing the crash msg
[2022-03-22T12:34:12Z] <testuser[m]> and glibc is not returning EDEADLK
[2022-03-22T12:48:31Z] <testuser[m]> the tests that get stuck on musl seem to pass aswell
[2022-03-22T12:54:03Z] <illiliti> because glibc uses direct gettid syscall for raise()
[2022-03-22T12:54:30Z] <illiliti> that's why it doesn't get stuck
[2022-03-22T12:56:15Z] <illiliti> does sigtrap show up in dmesg?
[2022-03-22T12:56:19Z] <testuser[m]> no
[2022-03-22T12:56:30Z] <illiliti> segfault?
[2022-03-22T12:57:02Z] <testuser[m]> nothing
[2022-03-22T12:57:05Z] <testuser[m]> just tab frozen
[2022-03-22T13:03:57Z] <illiliti> i think that's enough to confirm that bug in tid caching
[2022-03-22T13:04:04Z] <illiliti> tab frozed or crashed doesn't matter
[2022-03-22T13:04:14Z] <testuser[m]> yeah
[2022-03-22T13:04:28Z] <testuser[m]> i was recording it but looks like some recent wlroots commit broke wf-recorder lol
[2022-03-22T13:04:31Z] <testuser[m]> will bisect it
[2022-03-22T13:08:19Z] <illiliti> https://source.chromium.org/chromium/chromium/src/+/main:content/zygote/zygote_linux.cc;l=425
[2022-03-22T13:10:27Z] <testuser[m]> what about it
[2022-03-22T13:10:33Z] <illiliti> i think suid-based sandbox is worth checking
[2022-03-22T13:10:39Z] <illiliti> i bet it should work
[2022-03-22T13:11:01Z] <testuser[m]> yea i thought about it too
[2022-03-22T13:13:41Z] <illiliti> i'll try to rewrite ForkInNewPidNamespace to use fork/_Fork instead
[2022-03-22T13:26:47Z] <testuser[m]> illiliti: how to force use of SUID sandbox instead of user ns?
[2022-03-22T13:28:06Z] <illiliti> see post-install script
[2022-03-22T13:39:00Z] <testuser[m]> illiliti: curl -L http://0x0.st/oNvD.so > /usr/lib/chromium/chrome-sandbox; chown it to root:root and chmod u+s

[2022-03-22T13:39:54Z] <illiliti> try to check ForkInNewPidNamespace test with this patch: http://ix.io/3Taw
[2022-03-22T13:41:16Z] <testuser[m]> ok
[2022-03-22T13:44:25Z] <testuser[m]> btw use this http://0x0.st/oNvD.so, if the other one has DCHECK failures
[2022-03-22T13:48:05Z] <testuser[m]> building rn, but ForkWithFlags is in a couple of other places aswell so maybe u could just modify that function instead and ignore args: https://termbin.com/nrcb
[2022-03-22T13:50:33Z] <illiliti> will do, but for now check this one
[2022-03-22T13:50:49Z] <illiliti> and chrome-sandbox doesn't work for me
[2022-03-22T13:50:51Z] <illiliti> The setuid sandbox provides API version 1, but you need 0
[2022-03-22T13:59:09Z] <testuser[m]> illiliti: https://termbin.com/troj lol
[2022-03-22T14:08:06Z] <illiliti> glibc or musl?
[2022-03-22T14:08:43Z] <testuser[m]> musl
[2022-03-22T14:10:31Z] <testuser[m]> it has some weird longjmp magic going on too, in the original code

[2022-03-22T15:39:46Z] <testuser[m]> i might be able to strace and get the raw bytes its reading from the pipe and then interpret it as pid_t lol
[2022-03-22T15:39:56Z] <illiliti> did you compile with -ggdb?
[2022-03-22T15:41:14Z] <testuser[m]> no just with symbol_level. It barely built with that option I doubt my swap would be enough for ggdb

[2022-03-22T16:12:48Z] <testuser[m]> its unrelated but the code just seemed funny
[2022-03-22T16:20:35Z] <illiliti> testuser[m]: no idea, it looks like c++ nonsense

[2022-03-22T16:24:16Z] <illiliti> agree
[2022-03-22T16:24:28Z] <illiliti> quite tedious to read chromium code
[2022-03-22T16:24:56Z] <illiliti> i'll setup swap and continue though...
