The namespace cleanup path leaks a dentry which holds a reference count on a network namespace. Keeping that network namespace from being freed when the last user goes away. Leaving things like vlan devices in the leaked network namespace. If you use ip netns add for much real work this problem becomes apparent pretty quickly. It light testing the problem hides because frequently you simply don't notice the leak. Use d_set_d_op() so that DCACHE_OP_* flags are set correctly. This issue exists back to 3.0. Acked-by: "Eric W.

looks like a two different bugs IMHO first was "does not release pid_namespace slabs at all" (fixed in 905ad269c55fc62bee3da29f7b1d1efeba8aa1e1) second is "leaks some", exists in oS 12.1 with 905ad269c55fc62bee3da29f7b1d1efeba8aa1e1 patch applied, exists in oS 11.4 too, and somehow related to the presence of SIGCHLD handler with waitpid() Is it possible to fork a new bug from this one ?

Vadim, your test isn't going to produce decent results. Checking one value afterwards doesn't work because the pid_namespace slab is emptied gradually.

pid_namespace stays 21 and mnt_cache stays 60 forever instead of shrinking back to initial 0 and 39 please look at the comment 18, this is a different bug IMHO (race with signal code ?)

Mainline with voluntary preempt leaks heavily here. It does not leak at all if you ensure that the parent exits before children, so reparent is innocent.

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

Including proc_fs.h in fork.c breaks kABI in SLE11-SP2 for some reason. Have to double check 12.1, then push both. To put the final touches on this bug, namespaces are flat not amenable to the high frequency fork/exit/waitpid usage vsftpd is apparently doing. Children call synchronize_rcu() on exit, making them stick around for a while, and worse, the parent calls rcu_barrier() on each and every unmount while reaping since d863b50ab 2.6.38-rc5, meaning 1 child per tick is all it can reap. With many children to reap, zombies persist for ages as targets of readdir() in procfs, bloating cache. -- 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.
