Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec
Steffen Klassert says: ==================== 1) Fix a sleep in atomic when pfkey_sadb2xfrm_user_sec_ctx() is called from pfkey_compile_policy(). Fix from Nikolay Aleksandrov. 2) security_xfrm_policy_alloc() can be called in process and atomic context. Add an argument to let the callers choose the appropriate way. Fix from Nikolay Aleksandrov. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
