====================
pull request (net): ipsec 2018-10-01
1) Validate address prefix lengths in the xfrm selector,
otherwise we may hit undefined behaviour in the
address matching functions if the prefix is too
big for the given address family.
2) Fix skb leak on local message size errors.
From Thadeu Lima de Souza Cascardo.
3) We currently reset the transport header back to the network
header after a transport mode transformation is applied. This
leads to an incorrect transport header when multiple transport
mode transformations are applied. Reset the transport header
only after all transformations are already applied to fix this.
From Sowmini Varadhan.
4) We only support one offloaded xfrm, so reset crypto_done after
the first transformation in xfrm_input(). Otherwise we may call
the wrong input method for subsequent transformations.
From Sowmini Varadhan.
5) Fix NULL pointer dereference when skb_dst_force clears the dst_entry.
skb_dst_force does not really force a dst refcount anymore, it might
clear it instead. xfrm code did not expect this, add a check to not
dereference skb_dst() if it was cleared by skb_dst_force.
6) Validate xfrm template mode, otherwise we can get a stack-out-of-bounds
read in xfrm_state_find. From Sean Tranchetti.
Please pull or let me know if there are problems.
