Bug 557548 – dev-vcs/git makes dbus calls during source fetch, triggering sandbox violations if using kdbus

• Product: Gentoo Linux
• Status: RESOLVED OBSOLETE

[Description Mads 2015-08-14 12:55:53 UTC]

On a system booted with a kdbus-enabled systemd, git will trigger lots of open_wr sandbox violations for /sys/fs/kdbus/0-system/bus when fetching sources. This makes all live ebuilds fetches through git fail to install.


Reproducible: Always

Steps to Reproduce:
1. Install git (I've got dev-vcs/git-2.5.0 with these flags enabled: blksha1 curl gpg iconv nls pcre threads webdav)
2. Use a system booted with systemd and kdbus enabled (gentoo-sources with +experimental +kdbus)
3. Try to install a live ebuild


Actual Results:  
emerge -av btrfs-sxbackup # this is a local ebuild

[Comment 1 Lars Wendler (Polynomial-C) (RETIRED) 2015-08-14 14:20:23 UTC]

This is something I won't be able to look into as I neither use systemd nor am I going to use kdbus in the near future. Sorry if that sounds quite disappointing but I don't have any free resources to set up a Gentoo environment with systemd/kdbus.

[Comment 2 Robin Johnson 2020-12-07 07:32:39 UTC]

I believe this ticket is obsolete, if the problem persists, please reopen
