Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec
Steffen Klassert says: ==================== pull request (net): ipsec 2018-05-31 1) Avoid possible overflow of the offset variable in _decode_session6(), this fixes an infinite lookp there. From Eric Dumazet. 2) We may use an error pointer in the error path of xfrm_bundle_create(). Fix this by returning this pointer directly to the caller. Please pull or let me know if there are problems. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
