[Bug 1306877] Re: sshd stops accepting new connections after configuration reload
Thank you for taking the time to report this bug and helping to make Ubuntu better. Setting Importance to Critical as this is an expected harmless operation that will render the system essentially unreachable (and thus unusable) for remote users (eg. just about all server users). It seems to me that the STOP patch should only activate on first run, not on a re-exec. I'll take a look. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openssh in Ubuntu. https://bugs.launchpad.net/bugs/1306877 Title: sshd stops accepting new connections after configuration reload To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/1306877/+subscriptions -- 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 1306877] Re: sshd stops accepting new connections after configuration reload
openssh in Saucy (1:6.2p2-6ubuntu0.1) doesn't have this issue. Looks like its upstart job doesn't set SSH_SIGSTOP, use expect stop, and doesn't have the patch. So I think the bug is in the patch applied in Trusty. Fix attached. It seems to work. I'd appreciate a review of what I've done, though. ** Patch added: sigstop-reexec.debdiff https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/1306877/+attachment/4083307/+files/sigstop-reexec.debdiff -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openssh in Ubuntu. https://bugs.launchpad.net/bugs/1306877 Title: sshd stops accepting new connections after configuration reload To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/1306877/+subscriptions -- 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

This is the change I mentioned above: https://github.com/nya3jp/openssh-debian/commit/0334ce32304e9ba2a10ee5ca49ca6e8ff3ba6cf4 As a workaround, I commented out these two lines in /etc/init/ssh.conf: # env SSH_SIGSTOP=1 # expect stop Now initctl reload ssh works fine, though I'm not really sure I'm doing a right thing. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openssh in Ubuntu. https://bugs.launchpad.net/bugs/1306877 Title: sshd stops accepting new connections after configuration reload To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/1306877/+subscriptions -- 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
