[Bug 412972] Re: bad signal mask of ssh sessions
This looks related to http://bugs.debian.org/cgi- bin/bugreport.cgi?bug=549376, as I (the original reporter of that bug) am seeing the same SigBlk mask on my root sshd process. It may also be related to https://bugzilla.mindrot.org/show_bug.cgi?id=271 where sshd was inheriting a bad signal mask from somewhere else. ** Bug watch added: Debian Bug tracker #549376 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=549376 ** Bug watch added: OpenSSH Portable Bugzilla #271 https://bugzilla.mindrot.org/show_bug.cgi?id=271 -- bad signal mask of ssh sessions https://bugs.launchpad.net/bugs/412972 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openssh in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 412972] Re: bad signal mask of ssh sessions
I'm running Debian Unstable booting with file-rc, and there are several system daemons that have screwy SigBlk masks, of which sshd is one. They are listed in the attached commands file. You can get the data for a similar report on your own machine by running the following commands (as root): grep SigBlk /proc/*/status | grep -v commands for x in $(grep SigBlk /proc/*/status | grep -v | sed -e 's@/proc/\(.*\)/status...@\1@g'); do echo -n $x:; cat /proc/$x/cmdline; echo; done commands After running this, I cleaned things up a bit in vim to better organize the report. Perhaps people experiencing this bug on Ubuntu could run a similar report? ** Attachment added: System daemons with screwy sigprocmasks on Debian Unstable http://launchpadlibrarian.net/33042949/commands -- bad signal mask of ssh sessions https://bugs.launchpad.net/bugs/412972 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openssh in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

[Bug 412972] Re: bad signal mask of ssh sessions
Thanks, this confirms what we expected. The TERM signal is being delivered to the process, it's just that the process's mask is set to block that signal and it's still pending. We're not entirely sure yet what causes this bug; it's certainly not a procps or kernel bug, so I'm reassigning to openssh for the time being since that seems to be the key process. ** Package changed: procps (Ubuntu) = openssh (Ubuntu) ** Changed in: openssh (Ubuntu) Status: Incomplete = Confirmed -- bad signal mask of ssh sessions https://bugs.launchpad.net/bugs/412972 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openssh in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
