[2022-03-22T01:41:34Z] 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] it's tight knit & gucci :v

[2022-03-22T01:52:34Z] 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] honestly, what more could you want

[2022-03-22T03:22:51Z] hi guys

[2022-03-22T03:24:04Z] how i add alias permanently in my system?

[2022-03-22T03:25:47Z] add it to your shell rc file

[2022-03-22T03:26:26Z] You need to set one for busybox ash IIRC

[2022-03-22T03:26:40Z] so put "ENV=~/.ashrc" in ~/.profile

[2022-03-22T03:26:50Z] then your aliases in ~/.ashrc

[2022-03-22T03:27:58Z] okay

[2022-03-22T03:28:21Z] so .profile is not like a ashrc?

[2022-03-22T03:28:29Z] all that time i used like it

[2022-03-22T03:34:05Z] .profile is read by the login shell, and rc files are read by interactive shells

[2022-03-22T03:34:54Z] so if you set an environment variable in .profile, you'll have to log out and in again to have it take effect systemwide

[2022-03-22T09:33:54Z] hi everyone

[2022-03-22T09:34:20Z] i'm having some issues installing kiss linux

[2022-03-22T09:34:58Z] when i run cd /var/db/kiss/installed && kiss build *

[2022-03-22T09:35:20Z] i get this error ERROR pigz Failed to download https://zlib.net/pigz/pigz-2.6.tar.gz

[2022-03-22T09:39:06Z] xd

[2022-03-22T09:39:11Z] <testuser[m]> lol

[2022-03-22T09:46:00Z] i don't have spare space to create swap partition

[2022-03-22T09:46:05Z] and swap as pool on zfs is quite unstable

[2022-03-22T09:46:09Z] https://github.com/openzfs/zfs/issues/7734

[2022-03-22T09:47:43Z] 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

[2022-03-22T10:12:55Z] try in gdb: thread apply all backtrace

[2022-03-22T10:20:32Z] 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] 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] i think --single-process implies --no-sandbox, not vice-versa

[2022-03-22T10:38:37Z] but i may be wrong

[2022-03-22T10:38:44Z] https://source.chromium.org/chromium/chromium/src/+/main:sandbox/linux/services/namespace_sandbox.cc;l=115?q=MaybeUpdateGlibc&sq=

[2022-03-22T10:40:20Z] we need this func for musl

[2022-03-22T10:43:32Z] https://source.chromium.org/chromium/chromium/src/+/main:sandbox/linux/services/namespace_sandbox.cc;l=225

[2022-03-22T10:44:01Z] ForkInNewPidNamespace uses this hack to update tid on clone()

[2022-03-22T10:46:12Z] the equivalent hack for musl should fix the bug i guess

[2022-03-22T10:47:58Z] we can also attempt to rewrite this func to use fork+setns instead of clone

[2022-03-22T10:48:35Z] theoretically, this should fix bug too

[2022-03-22T10:53:34Z] https://source.chromium.org/chromium/chromium/src/+/main:base/threading/platform_thread_posix.cc;l=213-227

[2022-03-22T10:53:54Z] interesting

[2022-03-22T10:57:59Z] 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] 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] testuser[m]: libretls 3.5.1 has been released

[2022-03-22T11:51:06Z] <testuser[m]> phoebos: done

[2022-03-22T11:51:32Z] :)

[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] interesting commit message :p

[2022-03-22T11:55:38Z] 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] 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] because glibc uses direct gettid syscall for raise()

[2022-03-22T12:54:30Z] that's why it doesn't get stuck

[2022-03-22T12:56:15Z] does sigtrap show up in dmesg?

[2022-03-22T12:56:19Z] <testuser[m]> no

[2022-03-22T12:56:30Z] segfault?

[2022-03-22T12:57:02Z] <testuser[m]> nothing

[2022-03-22T12:57:05Z] <testuser[m]> just tab frozen

[2022-03-22T13:03:57Z] i think that's enough to confirm that bug in tid caching

[2022-03-22T13:04:04Z] 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] 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] i think suid-based sandbox is worth checking

[2022-03-22T13:10:39Z] i bet it should work

[2022-03-22T13:11:01Z] <testuser[m]> yea i thought about it too

[2022-03-22T13:13:41Z] 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] 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] 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] will do, but for now check this one

[2022-03-22T13:50:49Z] and chrome-sandbox doesn't work for me

[2022-03-22T13:50:51Z] 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] 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

[2022-03-22T14:29:04Z] http://ix.io/3TaR

[2022-03-22T14:31:44Z] <testuser[m]> ok

[2022-03-22T14:57:57Z] can you set breakpoint after ForkWithFlags?

[2022-03-22T15:27:23Z] <testuser[m]> there are 2 calls to ReceiveFixedMessage, a CHECK after that and a call to EnsureProcessGetsReaped. Only the 2 ReceiveFixedMessage get called so ig the bug is

[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] 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] testuser[m]: no idea, it looks like c++ nonsense

[2022-03-22T16:24:16Z] agree

[2022-03-22T16:24:28Z] quite tedious to read chromium code

[2022-03-22T16:24:56Z] i'll setup swap and continue though...
