[arch-general] Fwd: glibc flagged out-of-date
by Fabiano Furtado Pessoa Coelho 19 Nov '21

Hi.... Why is Arch Linux core repository still using glibc version 2.33? Why not upgrade the core repository to version 2.34, since it was flagged out-of-date on 2021-08-02? Thanks.

[arch-general] matrix-synapse "enhanced" security
by Uwe Sauter 18 Nov '21

18 Nov '21

Dear all, beginning with matrix-synapse 1.44.0-1 in early October a Systemd override file (see below for reference) was included to the package that aims to enhance the security of Synapse. Amongst other things it tells Systemd to restrict access to certain directories that are seen as defaults. Unfortunately this enhancement broke my setup by neglecting that there are various paths inside Synapse's configuration that can be customized, e.g. media_store_path and uploads_path. The error I see in my logs is: 2021-11-18 19:54:30,772 - synapse.rest.media.v1.preview_url_resource - 559 - WARNING - expire_url_cache_data-1281 - Failed to remove media directory: '/srv/matrix/media_store/url_cache/2021-10-08': [Errno 30] Read-only file system: '/srv/matrix/media_store/url_cache/2021-10-08' 2021-11-18 19:54:30,774 - synapse.rest.media.v1.preview_url_resource - 617 - WARNING - expire_url_cache_data-1281 - Failed to remove media: '2021-10-08_cgWYZUYMTRBdzskW': [Errno 30] Read-only file system: '800-450-image-jpeg-scale' It is also impossible to insert pictures into the chat. The client just tells "unable to send message" but no log entry is created on the server. Did I miss any notification about this change? Can anyone help me with customizing the Systemd override file so that Synapse regains access to media_store_path and uploads_path? Any help is appreciated. Thank you, Uwe ### /usr/lib/systemd/system/synapse.service.d/override-hardened.conf ### [Service] # The following directives give the synapse service R/W access to: # - /run/synapse # - /var/lib/synapse # - /var/log/synapse RuntimeDirectory=synapse StateDirectory=synapse LogsDirectory=synapse ###################### ## Security Sandbox ## ###################### # Make sure that the service has its own unshared tmpfs at /tmp and that it # cannot see or change any real devices PrivateTmp=true PrivateDevices=true # We give no capabilities to a service by default CapabilityBoundingSet= AmbientCapabilities= # Protect the following from modification: # - The entire filesystem # - sysctl settings and loaded kernel modules # - No modifications allowed to Control Groups # - Hostname # - System Clock ProtectSystem=strict ProtectKernelTunables=true ProtectKernelModules=true ProtectControlGroups=true ProtectClock=true ProtectHostname=true # Prevent access to the following: # - /home directory # - Kernel logs ProtectHome=tmpfs ProtectKernelLogs=true # Make sure that the process can only see PIDs and process details of itself, # and the second option disables seeing details of things like system load and # I/O etc ProtectProc=invisible ProcSubset=pid # While not needed, we set these options explicitly # - This process has been given access to the host network # - It can also communicate with any IP Address PrivateNetwork=false RestrictAddressFamilies=AF_INET AF_INET6 AF_UNIX IPAddressAllow=any # Restrict system calls to a sane bunch SystemCallArchitectures=native SystemCallFilter=@system-service SystemCallFilter=~@privileged @resources @obsolete # Misc restrictions # - Since the process is a python process it needs to be able to write and # execute memory regions, so we set MemoryDenyWriteExecute to false RestrictSUIDSGID=true RemoveIPC=true NoNewPrivileges=true RestrictRealtime=true RestrictNamespaces=true LockPersonality=true PrivateUsers=true MemoryDenyWriteExecute=false ### EOF ###

[arch-general] Why no option to stay with clamav 103 since as a LTS release it will be supported longer then 104?
by David C. Rankin 17 Nov '21

17 Nov '21

All, Just curious why Arch doesn't also provide the option to track clamav_LTS which will stay with 103 and will be supported much longer than 104? I know, I know, Arch matches upstream, but when upstream provides both current and LTS, wouldn't it make sense to also package and provide LTS like with the kernel? (the packaging would be trivial and the same between the current and LTS aside from the source package for all purposes) Just a thought as there is real advantage to being able to track the clamav LTS release here, without hacking pacman.conf. There are few packages that actually provide a LTS branch so it wouldn't open the flood gates to a bevy of new packages. -- David C. Rankin, J.D.,P.E.

I added the patch to the linux PKGBUILD and the errors no longer appear. Is there a possibility to add that patch to the linux package? Don't really want to build the kernel every time it is updated.

[arch-general] Should PacBSD (Arch with BSD kernel) be revived?

PacBSD is a GNU/BSD distribution of Arch Linux but with the BSD kernel instead. Do you think it should be revived, as it seems to be dead with the website down and everything?

[arch-general] New LXQt (1.0.0) with big text size, affecting other Qt apps
by Javier 12 Nov '21

12 Nov '21

Hello ! I've been using LXQt for some time now (years), and with Today's Arch upgrade, which included a LXQt upgrade 0.17.0-1 -> 1.0.0-1, everything was showing app really big, from LXQt own text (menus, icons, widgets, etc) to other apps. The only work around I found was to reduce the font size on LXQt's preferences, and also on Qterminal, I had to change it from like 18 to 10 on Qterminal, and from 16 to 10 on LXQt itself. I still see other apps bigger than what they used to be, and in particular the apps' toolbar became wider, and the border surrounding Qt apps became wider (to the point it's annoying). It's not about manipulating QT_SCALE_FACTOR + QT_AUTO_SCREEN_SCALE_FACTOR, and the like, because that's to make things bigger when they look way to small and unreadable. Actually by setting QT_SCALE_FACTOR to 1, its the same behavior as not setting any variable, and lower than 0 values don't really work on Qt (I tried, and the results are really weird, non functional to say the least). Have other lxqt users experienced the same on Arch? Would it be an Arch building and packaging issue? Or this is totally an upstream thing? Thanks ! -- Javier

Hi all. After recent updates to arch I started having problems with some programs that make use of the gnome-keyring-daemon. When I run for example the command 'pass -c git-azure', the command takes about 15 seconds to ask for the password and the following messages appear in the log: Nov 09 11:13:26 jveii gpg-agent[124433]: Failed to lookup password for key n/1128A1F67CEF113D23CE021A5502F13DEE17610C with secret service: Error calling StartServiceByName for org.freedesktop.secrets: Timeout was reached Nov 09 11:13:01 jveii gnome-keyring-d[124438]: Couldn't connect to session bus: Cannot spawn a message bus when setuid Nov 09 11:13:01 jveii gnome-keyring-daemon[124438]: Couldn't connect to session bus: Cannot spawn a message bus when setuid Nov 09 11:13:01 jveii /usr/lib/gdm-x-session[124438]: SSH_AUTH_SOCK=/run/user/1000/keyring/sshNov 09 11:13:01 jveii gnome-keyring-daemon[783]: couldn't connect to dbus session bus: Cannot spawn a message bus when setuid Nov 09 11:13:01 jveii /usr/lib/gdm-x-session[795]: dbus-daemon[795]: [session uid=1000 pid=795] Activating service name='org.freedesktop.secrets' requested by ':1.1451' (uid=1000 pid=124433 comm="/usr/bin/pinentry-gtk-2 --display :0 ") I'm also having issues with other applications like vpn connections and chromium is taking a while to display the first page once it starts up. Does anyone have any idea what I might be doing wrong? Thank you very much in advance.
