PAM 1.6 breaks limits.conf parsing
by Simone Baratta 12 Apr '24

12 Apr '24

Howdy, Arch community! Today Ardour warned me that I had a ulimit enforced for locked memory, and indeed I was surprised to find that `ulimit -l` reported 8192 for my user (which I configured to `unlimited` a long time ago). After a bit of investigation, it turned out that this is a bug introduced by PAM 1.6, which fails to read my limits.conf file due to the extra whitespace separating entries: ``` @audio - memlock unlimited ``` This makes pam_limits.so fail with the following: ``` pam_limits(login:session): wrong limit value ' unlimited' for limit type '-' ``` Looks like this issue was introduced with [1], and indeed I can confirm that it's fixed by [2] which references the first commit. Is there any chance we can get a 1.6.0-5 update with this patch in? This version is already in core, and it's a very subtle issue which is likely to be unnoticed by many but come with a lot of (possibly security-relevant) side effects.

Re: [arch-announce] The xz package has been backdoored

Truly an astounding revelation. This is a very, very sophisticated tool-chain attack along the lines of Ken Thompson's famous compiler trust example [1] Arch has been a strong advocate for reproducible builds [2] which can be part of a defense strategy [2]. I note that our xz package is marked as good in this regard [3]. I wonder what more we can reasonably do in the near term. Since git gives us decent tools to check what changed etc., I would imagine that can provide a stronger base on which to check things than working with tarballs or tarballs alone. This may have gone largely un-noticed for so long as people are probably more likely to check the source than the tarball itself. In this case, it seems, it was a primary developer doing the naughty - but they chose to leave the git repo alone and only infect the tarball. Question: -------- Would it make sense, therefore, to switch builds, where possible, away from tar files and instead pull directly from git source (signed tags where possible as usual etc)? Of course a git repo can also carry infections - perhaps taht's a little less likely. Or is this not worth the trouble?

Which Emacs package?
by Abraham S.A.H. 31 Mar '24

31 Mar '24

Hey fellows; There are many Emacs packages available across Arch repositories and AUR. I list some of them here, in no specific order: From Extra repository: * emacs * emacs-wayland * emacs-nativecomp * emacs-nox From AUR and some third party repositories: * emacs-lucid-nativecomp * emacs-git * chaotic-aur/emacs-pgtk-native-comp-git I do not explain any of them for details. My audience is the one who already tried them, so can give me some advice. I already have tried all of them and also read archwiki's Emacs article. The Lucid one seems like the most stable with the least bugs, but with an archaic UI and without dnd support, but I do not use those scroll/menu/toolbars. Please, if you have any experience, share it with me. -- Best Regards, Abraham Sent with Tutanota; https://tuta.com

man.archlinux.org/man/xzmore.1.uk is not in English
by u34＠net9.cf 30 Mar '24

30 Mar '24

https://man.archlinux.org/man/xzmore.1.uk manual page is not in English. Visually, I would say my local copy, man -l /usr/share/man/uk/man1/xzmore.1.gz , and xzmore.1.uk at man.archlinux.org have the same text. I also have many warnings, for a lot of packages, from pacman -Qkk. One of these warnings is about /usr/share/man/uk/man1/xzmore.1.gz. The warning is despite the fact the actaul data for /usr/share/man/uk/man1/xzmore.1.gz seems to agree with zgreping /var/lib/pacman/local/xz-5.6.1-2/mtree for that file. Local pacman version is 6.0.2-9. -- u34

Why after rebuild do I still get "warning: normalize: unknown key 'makepkgopt' in package description"?
by David C. Rankin 28 Mar '24

28 Mar '24

All, In whatever changed a week or so ago, pacman gave "... unknown key 'makepkgopt' in package description" for a slew of old packages left on my system from a decade of use. I've since gone back and removed all the packages and rebuilt the ones I need, but I still get a handful of errors for the 'normalize' package I've just built. What am I doing wrong? On cleaning the cache I get: 20:11 valkyrie:~> pms -c Packages to keep: All locally installed packages Cache directory: /var/cache/pacman/pkg/ :: Do you want to remove all other packages from cache?

Re: Proposal to increase the default vm.max_map_count value
by Rein Fernhout (Levitating) 25 Mar '24

25 Mar '24

Seeing as other distributions have already adopted this change and gaming is a popular usecase for ArchLinux I do think this is a good thing to have. The default value will only be more of a bottleneck in the future. There's a balance in sticking to defaults. It'd be a shame if users need to alter multiple kernel parameters just to play modern games or run other applications with a high memory footprint. As I understand it there's no real downside to increasing this. Could someone with more knowledge of the kernel shed some light on any possible adverse effects that might come from increasing the default? I am also curious how the upstream discussed will go but I do not expect them to change it.

Where to find old png2ico PKGBUILD it was dropped to AUR?
by David C. Rankin 24 Mar '24

24 Mar '24

All, Cleaning up old packages, I still need the png2ico utility. It is no longer in AUR replaced by elphicon which uses that abomination electron. I need to know if the old PKGbUILD for Arch png2ico still exists in some historical form somewhere. It would save writing another. What say the historians, does such a thing exist? -- David C. Rankin, J.D.,P.E.

CLI access to dropbox

Hey hey, I need CLI access to my dropboox account. I'm still running dropbox-cli, which is marked as out-of-date and I couldn't update to the latest version. Using trizen, I get this error message: [...] -> Found dropboxd-fallback.patch ==> Validating source files with sha256sums... dropbox-cli-2023.09.06.py ... FAILED dropboxd-fallback.patch ...
