[Bug 603363] Re: sshd never stops, prevents umount of /usr partition
** Description changed: Under Ubuntu 10.04 Lucid, sshd is an upstart job controlled by /etc/init/ssh.conf This file provides for start and stop as follows: start on filesystem stop on runlevel S At shutdown or reboot, therefore, sshd is not stopped. Since sshd is in /usr/sbin/sshd and also accesses lib files in /usr/lib this means that /etc/rc0.d/S40umountfs cannot successfully umount /usr at shutdown when /usr is on its own partition. This definitely leads to umount reporting errors in the shutdown console messages. It may also lead to fsck running on reboot and problems with mountall... I can't say for certain yet as I am also having problems umounting /var, possibly due to a power failure, which is what led me to notice and investigate these messages. My guess is that when sshd was a System V init process, it was killed by the killall5 process in /etc/rc0.d/S20sendsigs. Under Lucid sshd has been made an upstart job and as such is exempt from the killall5 and so needs to be stopped explicitly. I admit I am by no means an expert on upstart or sshd, but the fix appears to me to be to modify /etc/init/ssh.conf to read stop on runlevel [!2345] ProblemType: Bug DistroRelease: Ubuntu 10.04 Package: openssh-server 1:5.3p1-3ubuntu4 ProcVersionSignature: Ubuntu 2.6.32-22.36-generic 2.6.32.11+drm33.2 Uname: Linux 2.6.32-22-generic x86_64 Architecture: amd64 Date: Thu Jul 8 14:45:50 2010 InstallationMedia: Ubuntu 10.04 LTS Lucid Lynx - Release amd64 (20100427.1) ProcEnviron: - LANG=en_US.UTF-8 - SHELL=/bin/bash + LANG=en_US.UTF-8 + SHELL=/bin/bash SourcePackage: openssh + + == SRU Report == + + === Impact / Justification === + + This bug can lead to filesystem corruption if /usr is on a separate + filesystem or if sshd isn't restarted on libc6 upgrade (which is almost + guaranteed due to bug #531912) + + === Dev fix === + + This was fixed in the dev branch by making sshd stop on runlevel + [!2345], which is fairly standard for network services. + + === Patch === + + See attached debdiff + + === TEST CASE: === + + On a lucid system with all updates applied + 1. sudo apt-get install openssh-server + 2. verify it is started and running with 'sudo status ssh' + 3. sudo apt-get install --reinstall libc6 + 4.

Good question.
