http://bugzilla.opensuse.org/show_bug.cgi?id=980521 Bug ID: 980521 Summary: gvfs fuse mounts do not appear breaking access for legacy apps Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: SUSE Other Status: NEW Severity: Normal Priority: P5 - None Component: GNOME Assignee: bnc-team-gnome@forge.provo.novell.com Reporter: novell@mirell.de QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Created attachment 677410 --> http://bugzilla.opensuse.org/attachment.cgi?id=677410&action=edit openSUSE Tumbleweed 20160516 GVFS fuse mounts not appearing I noticed that on openSUSE Tumbleweed latest snapshot, including the 20160516 live CD, GVFS fuse mounts for accessing remote locations using "/run/user/1000/gvfs" are not working (see attachment). Manually restarting "gvfsd-fuse" makes them appear again if mounts are added/removed. Therefore this breaks all legacy applications which access a mount's files using the filesystem and not with GIO directly. This can be tested by logging in, then running "gvfs-mount localtest:///". The mountpoint does not appear in "/run/user/$(id)/gvfs". After some investigation with upstream (See https://bugzilla.gnome.org/show_bug.cgi?id=766433) it kind of points towards a problem around the DBUS session bus. Since you know the gdm/gnome-session/dbus-launch procedure of openSUSE better you might be able to help. -- You are receiving this mail because: You are on the CC list for the bug.

http://bugzilla.opensuse.org/show_bug.cgi?id=980521 http://bugzilla.opensuse.org/show_bug.cgi?id=980521#c2 --- Comment #2 from Martin Szulecki --- Nasty. I also have systems where I can't reproduce it (Macbooks). However it is visible when booting the live CD in a VM (the path is /run/user/999/gvfs in that case and use rootfstype=ramfs if you get a kernel panic) and some desktop systems. Could you please check if "ps ax | grep gvfsd" only gives you a single gvfsd instance? -- You are receiving this mail because: You are on the CC list for the bug.

http://bugzilla.opensuse.org/show_bug.cgi?id=980521 http://bugzilla.opensuse.org/show_bug.cgi?id=980521#c4 --- Comment #4 from Martin Szulecki --- Ok, thanks. It kind of proves my point. On systems with only a single "gvfsd" running after login everything works normally as the DBUS session bus is the same. On systems with two "gvfsd" running after login the issue comes up as "gvfsd-fuse" doesn't get the mount messages most likely because it's using a different DBUS session bus. I can reproduce the issue on a clean openSUSE Tumbleweed Live CD system in a VM (see screenshot). The other systems can not be considered absolutely clean installs. It isn't fixed after installing obs binary packages directly and I am nevertheless using a branched GNOME:Factory "gvfs" with added debugging on affected systems. Also tested running the same system with nouveau instead of the NVIDIA blob and got a single "gvfsd" with working mounts... It smells like a nasty thing somewhere in the gdm/login/xsession process. -- You are receiving this mail because: You are on the CC list for the bug.

I updated the upstream bug with more information and reassigned to gdm for a final clarification and also attached the same file here fore completeness. Do you know how to determine what started the second gvfsd instance? Does the pstree in the usptream bug look correct as, if I understood correctly, upstream says "gdm-x-session" should also be run as gdm user? -- You are receiving this mail because: You are on the CC list for the bug.

Looks like it is indeed openSUSE related. I found out what resets the dbus session bus address. It is the DBUS check within "/etc/X11/xdm/sys.xsession". If I comment out the whole "Check if a dbus is required for e.g. plain xdm sessions" block, the dbus user session is correctly propagated to gnome-session and all afterwards starts up correctly. GVFS works and only has a single process running. This also applies to the openSUSE TW Live CD... gvfs works in that case again, too. Still need to check why the logic fails. -- You are receiving this mail because: You are on the CC list for the bug.

New subject: [Bug 980521] gvfs fuse mounts do not appear breaking access for legacy apps

http://bugzilla.opensuse.org/show_bug.cgi?id=980521 http://bugzilla.opensuse.org/show_bug.cgi?id=980521#c7 --- Comment #7 from Martin Szulecki --- So, when "gdm-x-session" runs "/etc/gdm/Xsession" is called. Due to SuSE specific patches that also runs "/etc/X11/xdm/Xsession" which runs "/etc/X11/xdm/sys.xsession". However, when "gdm-x-session" is run, it spawns a new user session bus already if one was not yet started for the user. Thus DBUS_SESSION_BUS_ADDRESS will be populated with a valid session. Once within the "sys.xsession" script, it will destroy the valid session with the line "test -n "$dpid" || unset DBUS_SESSION_BUS_ADDRESS", which causes a new dbus user session to be created by the script and causes havok later on for the dbus user session pingpong of GVFS and other GNOME related components. As far as I understand this really messy startup procedure... I think it should not unset a valid DBUS_SESSION_BUS_ADDRESS and therefore not start a new dbus-daemon in the "gdm" case to fix proper GNOME session startup for "gdm". -- You are receiving this mail because: You are on the CC list for the bug.

Created attachment 678158 [details] /etc/X11/xdm/sys.xsession

Yet an other /etc/X11/xdm/sys.xsession. With this now the dbus-send command is used to check for a valid dbus-daemon session. For testing please replace the current /etc/X11/xdm/sys.xsession with the attachment. Note that you might run

chmod 755 /etc/X11/xdm/sys.xsession

afterwards. Now does this new version fix the problem?

The "sys.xsession" has a syntax error in line 122. After fixing it, I can confirm it works. There is also an example in the man page of dbus-launch regarding testing for the dbus-daemon but I am not sure if this is the "correct" way: https://dbus.freedesktop.org/doc/dbus-launch.1.html -- You are receiving this mail because: You are on the CC list for the bug.
