You are likely already aware, but sharing as saw no mention about this in the rfc discussion. There aare these comments from Fedora / Redhat regarding level 3 and systemd not working with it which looks relevant [1] [2] "There are packages (e.g. systemd) that do not interact well with _FORTIFY_SOURCE and will also need a workaround to downgrade fortification to level 2. " and in detail: "_FORTIFY_SOURCE=3 revealed another pattern. Applications such as systemd used malloc_usable_size to determine available space in objects and then used the residual space. The glibc manual discourages this type of usage, dictating that malloc_usable_size is for diagnostic purposes only. But applications use the function as a hack to avoid reallocating buffers when there is space in the underlying malloc chunk. The implementation of malloc_usable_size needs to be fixed to return the allocated object size instead of the chunk size in non-diagnostic use. Alternatively, another solution is to deprecate the function. But that is a topic for discussion by the glibc community." regards gene [1] https://fedoraproject.org/wiki/Changes/Add_FORTIFY_SOURCE%3D3_to_distributi… [2] https://developers.redhat.com/articles/2022/09/17/gccs-new-fortification-le…

Weird Firefox & Thunderbird Context Menu/Right Click Bug
by NicoHood 17 Jan '23

17 Jan '23

Hey guys, I dont know where to report this, as it could be related to firefox, thunderbird or gnome (or any other desktop related software). In the last 1-2 Weeks (I dont update that often) I noticed that after some time (have not found a reproducible reason) right clicks, or context menus in genral in Firefox stop working at all. The menu pops up for a few milliseconds and then disappear. When you restart firefox everything works again. I noticed the same isse in thunderbird too, which is also by mozilla. I did not notice it in any other application. I am using gnome as Desktop environment. Do you have the same issue? Any hint if this is a gnome, firefox or other issue? Cheers Nico

Obfuscation of emails
by Polarian 15 Jan '23

15 Jan '23

Hello, This point is highly controversial within the Arch community, I have seen a lot of people argue either side, but I want to share my opinion on this. Personally I think obfuscation of emails is a complete waste of time, and I am going to explain why. So lets take my email as an example, polarian(a)polarian.dev, people often always obfuscate in the same way: <polarian at polarian dot dev> now what stops a bot from substituting "at" with "@" and "dot" with ".", it is not hard to do, and quite frankly it is a pain to deobfuscate peoples emails within PKGBUILD files when you need to email them to report issues, or get into contact. I have read a lot of pages on the ArchWiki and they all promote obfuscation of emails, have seen discussions on discussing the pros and cons, and not saying obfuscation has no downsides, but none of the discussions amounted to anything. Can we please stop advertising obfuscation of emails, it is counter-productive, we have anti-spam measures, and bots can easily bypass the obfuscation unless you make it more sophisticated, but at that point people won't be able to understand the email and you will be uncontactable. All obfuscation does in my experience, is make it 100x harder for people to report issues, its counter productive in a lot of cases but yet Arch community still advertises. It is up to you personally if you want to obfuscate your email address in PKGBUILDs and other files, but PLEASE can we stop advertising it as a perfect solution to spam, because in many cases, it doesn't even protect you from spam, just is a hindrance for people who genuinely want to contact you.

Re: ROCm in [community]

Hi Torsten, thanks a lot for your work! I am here to ask if it's planned to create a group for these packages. That would make it a lot easier to install all of the (currently available) toolchain at once.

Mailing list to discuss ArchWiki?
by Polarian 08 Jan '23

08 Jan '23

Hello, I have realised a lot of the ArchWiki discussions are very empty, and have not been used for years for some of the pages. At first I thought this was because the pages were just not edited very often, but now I have realised that even the most popular pages do not have many discussions. Is there a mailing list for the ArchWiki, or do ArchWiki memebers use an alternative form of discussion to discuss wiki related subjects? Thank you, Polarian

Storage size of the ArchWiki
by Polarian 08 Jan '23

08 Jan '23

Hello, This is a bit of a random question, does anyone have an approximation or the actual size of the entire of the ArchWiki. This is not useful in the slightest, but I am genuinely curious to see how huge it would be, probably because of autism and weird obsession with numbers, but it would be cool to know. Thanks, Polarian

kernel 6.1 : suspend/resume problem - s2idle interference
by SET 07 Jan '23

07 Jan '23

Hi, I am requesting help for a suspend/resume problem on a laptop since kernel 6.1. The laptop randomly goes in s2idle mode instead of deep. Resuming from s2idle is the problem, it would most often result in a black screen, magic keys don't work and there's no choice than a hard reboot. The cycles below are grepped from everything.log (using syslog-ng). Jan 2 09:04:02 asus0 kernel: [ 272.442844] PM: suspend entry (s2idle) Jan 2 09:07:24 asus0 kernel: [ 81.496530] PM: suspend entry (s2idle) Jan 2 09:07:36 asus0 kernel: [ 94.219950] PM: suspend exit Jan 2 09:13:43 asus0 kernel: [ 74.020096] PM: suspend entry (deep) Jan 2 09:13:53 asus0 kernel: [ 78.968818] PM: suspend exit Jan 2 09:27:03 asus0 kernel: [ 831.165661] PM: suspend entry (deep) Jan 2 09:27:12 asus0 kernel: [ 835.967426] PM: suspend exit Jan 2 09:29:54 asus0 kernel: [ 103.750713] PM: suspend entry (deep) Jan 2 09:30:12 asus0 kernel: [ 122.122386] PM: suspend exit Jan 2 09:30:12 asus0 kernel: [ 122.122473] PM: suspend entry (s2idle) Jan 2 09:35:27 asus0 kernel: [ 66.427487] PM: suspend entry (deep) Jan 2 09:35:35 asus0 kernel: [ 71.262239] PM: suspend exit Jan 2 09:49:10 asus0 kernel: [ 101.216846] PM: suspend entry (deep) Jan 2 09:49:32 asus0 kernel: [ 122.833061] PM: suspend exit Jan 2 09:49:32 asus0 kernel: [ 122.833242] PM: suspend entry (s2idle) Jan 2 09:52:30 asus0 kernel: [ 96.227978] PM: suspend entry (deep) Jan 2 09:54:33 asus0 kernel: [ 101.035466] PM: suspend exit Jan 2 10:00:29 asus0 kernel: [ 456.496279] PM: suspend entry (deep) Jan 2 10:00:50 asus0 kernel: [ 476.827893] PM: suspend exit Jan 2 10:00:50 asus0 kernel: [ 476.828015] PM: suspend entry (s2idle) Jan 2 10:06:29 asus0 kernel: [ 149.561486] PM: suspend entry (deep) Jan 2 11:46:21 asus0 kernel: [ 155.932575] PM: suspend exit Using 'mem_sleep_default=deep' in '/etc/default/grub' (and grub-mkconfig afterwards) does not alter this behaviour. After removing the above parameter, i.e., the default, /sys/power/mem_sleep contains 's2idle [deep]'. I grant that 'deep' is the default suspend mode, though it does randomly go in 's2idle' on its own. /sys/power/state contains 'freeze mem disk'. After reverting to kernel 6.0.12-arch1, suspend/resume works normally, as it always did. I'm out of ideas for a fix, and would appreciate any clues.

Keyboard layout does not persist in /etc/vconsole.conf
by Björn Försterling 06 Jan '23

06 Jan '23

Hello, After finishing the Arch Linux installation (without desktop environment or X11) I can't make the keyboard layout persistent. (I am using the 01/2023 ISO as installation medium) I have set the keyboard layout to de-latin1 in /etc/vconsole.conf. This is the content of /etc/vconsole.conf: KEYMAP=de-latin1 Usually this works and the keyboard layout is permanent. But somehow systemd does not read it and after every reboot I am back to US layout. I tried to set the keyboard layout through a kernel parameter like this: GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 quiet vconsole.keymap=de-latin1" But it did not solve the issue. According to pstree systemd should be the init system. Does someone have an idea what could've gone wrong in the installation process? Regards Björn

Arch Keyring Up To Date but Errors in journal?

All, I saw a handful of Archlinux gpg errors in the journal and thought my arch keyring must need updating, so I issued the command to update the keyring -- and it was up to date: # pacman -Sy --needed archlinux-keyring :: Synchronizing package databases... core is up to date extra is up to date community is up to date cingg is up to date warning: archlinux-keyring-20221220-1 is up to date -- skipping there is nothing to do Why do I still see key Arch gpg errors in the journal, e.g.: Dec 30 22:47:56 valkyrie archlinux-keyring-wkd-sync[90563]: gpg: error retrieving 'alucryd(a)archlinux.org' via WKD: Connection timed out Dec 30 22:47:56 valkyrie archlinux-keyring-wkd-sync[90563]: gpg: error reading key: Connection timed out Dec 30 22:47:56 valkyrie archlinux-keyring-wkd-sync[90310]: Skipping key 42DFAFB7C03B2E4E7BBDBA69930B82BFC2BDA011 with UID muflone(a)vbsimple.net...
