Merge tag 'ipsec-next-2024-05-03' of git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec-next
Steffen Klassert says:
====================
pull request (net-next): ipsec-next 2024-05-03
1) Remove Obsolete UDP_ENCAP_ESPINUDP_NON_IKE Support.
This was defined by an early version of an IETF draft
that did not make it to a standard.
2) Introduce direction attribute for xfrm states.
xfrm states have a direction, a stsate can be used
either for input or output packet processing.
Add a direction to xfrm states to make it clear
for what a xfrm state is used.
* tag 'ipsec-next-2024-05-03' of git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec-next:
xfrm: Restrict SA direction attribute to specific netlink message types
xfrm: Add dir validation to "in" data path lookup
xfrm: Add dir validation to "out" data path lookup
xfrm: Add Direction to the SA in or out
udpencap: Remove Obsolete UDP_ENCAP_ESPINUDP_NON_IKE Support
