[PATCH 3.16.y-ckt 007/165] flowcache: Fix kernel panic in flow_cache_flush_task
3.16.7-ckt9 -stable review patch. If anyone has any objections, please let me
know.
--
From: Miroslav Urbanek
commit 233c96fc077d310772375d47522fb444ff546905 upstream.
flow_cache_flush_task references a structure member flow_cache_gc_work
where it should reference flow_cache_flush_task instead.
Kernel panic occurs on kernels using IPsec during XFRM garbage
collection. The garbage collection interval can be shortened using the
following sysctl settings:
net.ipv4.xfrm4_gc_thresh=4
net.ipv6.xfrm6_gc_thresh=4
With the default settings, our productions servers crash approximately
once a week. With the settings above, they crash immediately.
Fixes: ca925cf1534e ("flowcache: Make flow cache name space aware")
