Steffen Klassert says:

====================
pull request (net-next): ipsec-next 2026-06-12

1) Replace the open-coded manual cleanup in xfrm_add_policy() error
   path with xfrm_policy_destroy() for consistency with
   xfrm_policy_construct().
   From Deepanshu Kartikey.

2) Limit XFRMA_TFCPAD to a sensible maximum (max IP length, 64k) since
   u32 is excessive for traffic flow confidentiality padding.
   From David Ahern.

3) Add a new netlink message XFRM_MSG_MIGRATE_STATE that
   allows migrating individual IPsec SAs independently of
   their policies. The existing XFRM_MSG_MIGRATE is tightly coupled
   to policy+SA migration, lacks SPI for unique SA identification,
   and cannot express reqid changes or migrate Transport mode
   selectors. The new interface identifies the SA via SPI and mark,
   supports reqid changes, address family changes, encap removal,
   and uses an atomic create+install flow under x->lock to prevent
   SN/IV reuse during AEAD SA migration.
   From Antony Antony.
