Created an attachment (id=488769) --> (http://bugzilla.novell.com/attachment.cgi?id=488769) [details] leak fix
After finally convincing ftrace to capture the _whole_ event, turns out one leak is simple, SIGCHLD received during fork() triggers fork() failure - proc was mounted but not unmounted on cleanup.
There's at least one more (not so simple) leak though. The final put_pid() in softirq context occasionally just goes missing for some as yet unknown reason.
tried 3.1.10-1.9-desktop, -default and -xen (as a dom0 and domU kernel) with all three patches applied, vsftp and "netcat -z 127.0.0.1 21" loop no leak with -desktop and -xen dom0 pid_ns leaks with -default and -xen domU
Seems there are some nasty issues open in pid namespace as well, Oleg sent me this link:
Heh. Please look at http://marc.info/?l=linux-kernel&m=127687751003902 and the whole thread, there are a lot more problems here.
sad btw wonder why nobody reported this issue long time ago no one is using vsftpd on oS nowadays ? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
