* netns xfrm: deal with dst entries in netnsAlexey Dobriyan2010-01-25
| | | | | | | | | | | | | | | GC is non-existent in netns, so after you hit GC threshold, no new dst entries will be created until someone triggers cleanup in init_net. Make xfrm4_dst_ops and xfrm6_dst_ops per-netns. This is not done in a generic way, because it woule waste (AF_MAX - 2) * sizeof(struct dst_ops) bytes per-netns. Reorder GC threshold initialization so it'd be done before registering XFRM policies. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* net: Allow xfrm_user_net_exit to batch efficiently.Eric W. Biederman2009-12-03
| | | | | | | | | | | xfrm.nlsk is provided by the xfrm_user module and is access via rcu from other parts of the xfrm code. Add xfrm.nlsk_stash a copy of xfrm.nlsk that will never be set to NULL. This allows the synchronize_net and netlink_kernel_release to be deferred until a whole batch of xfrm.nlsk sockets have been set to NULL. Signed-off-by: Eric W.

* netns xfrm: per-netns sysctlsAlexey Dobriyan2008-11-25
| | | | | | | | | | | | | | | | | Make net.core.xfrm_aevent_etime net.core.xfrm_acq_expires net.core.xfrm_aevent_rseqth net.core.xfrm_larval_drop sysctls per-netns. For that make net_core_path[] global, register it to prevent two /proc/net/core antries and change initcall position -- xfrm_init() is called from fs_initcall, so this one should be fs_initcall at least.

* netns xfrm: per-netns state GC listAlexey Dobriyan2008-11-25
| | | | | | | | | | | km_waitq is going to be made per-netns to disallow spurious wakeups in __xfrm_lookup(). To not wakeup after every garbage-collected xfrm_state (which potentially can be from different netns) make state GC list per-netns.
