| * performance fix for podman events with large journaldsbaude2019-08-14
| | | | | | | | | | | | | | | | | | in the case where the host has a large journald, iterating the journal without using a Match is very poor performance. this might be a temporary fix while we figure out why the systemd library does not seem to behave properly.

* Fix up ConmonPidFile after restoreAdrian Reber2019-08-09
| | | | | | | | | | | | | | | | After restoring a container with a different name (ID) the ConmonPidFile was still pointing to the path of the original container. This means that the last restored container will overwrite the ConmonPidFile of the original container. It was also not possible to restore a container with a new name (ID) if the original container was not running. The ConmonPidFile is only changed if the ConmonPidFile starts with the value of RunRoot. This assumes that if RunRoot is part of ConmonPidFile the user did not specify --conmon-pidfile' during run or create. Signed-off-by: Adrian Reber <areber@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Old versions of conmon have a bug where they create the exit file before closing open file descriptors causing a race condition when restarting containers with open ports since we cannot bind the ports as they're not yet closed by conmon.

Swap to using our standard 'stop()' function instead of a custom one for force-remove, and move the event into the internal stop function (so internal calls also register it). This does add one more database save() to `podman remove`. This should not be a terribly serious performance hit, and does have the desirable side effect of making things generally safer.

This wasn't a memleak detectable by kmemleak for example. The kernel never lost track of the memory and there was no erroneous refcounting either. The reference count dependencies however are not easy to track because when a refcount is increased, there's no way to tell who's still holding the reference. In this case it was a single page of tmpfs pagecache holding a refcount that kept pinned a whole hierarchy of dying memcg, slab kmem, cgropups, unrechable kernfs nodes and the respective dentries and inodes. Such a problem wouldn't happen if the exit file was stored in a regular filesystem because the pagecache could be reclaimed in such case under memory pressure. The tmpfs page can be swapped out, but that's not enough to release the memcg with CONFIG_MEMCG_SWAP_ENABLED=y. No amount of more aggressive kernel slab shrinking could have solved this. Not even assigning slab kmem of dying cgroups to alive cgroup would fully solve this. The only way to free the memory of a dying cgroup when a struct page still references it, would be to loop over all "struct page" in the kernel to find which one is associated with the dying cgroup which is a O(N) operation (where N is the number of pages and can reach billions). Linking all the tmpfs pages to the memcg would cost less during memcg offlining, but it would waste lots of memory and CPU globally. So this can't be optimized in the kernel. A cronjob running this command can act as workaround and will allow all slab cache to be released, not just the single tmpfs pages. rm -f /run/libpod/exits/* This patch solved the memleak with a reproducer, booting with cgroup.memory=nokmem and with selinux disabled. The reason memcg kmem and selinux were disabled for testing of this fix, is because kmem greatly decreases the kernel effectiveness in reusing partial slab objects. cgroup.memory=nokmem is strongly recommended at least for workstation usage. selinux needs to be further analyzed because it causes further slab allocations.
