Subject: [PATCH v2 0/2] Fix issues in xfrm_migrate

From: Yan Yan <[email-masked]>

This patch series include two patches to fix two issues in xfrm_migrate.

PATCH 1/2 enables distinguishing SAs and SPs based on if_id during the
xfrm_migrate flow. It fixes the problem that when there are multiple
existing SPs with the same direction, the same xfrm_selector and
different endpoint addresses, xfrm_migrate might fail.

PATCH 2/2 enables xfrm_migrate to handle address family change by
breaking the original xfrm_state_clone method into two steps so as to
update the props.family before running xfrm_init_state.

V1 -> V2:
- Move xfrm_init_state() out of xfrm_state_clone()
and called it after updating the address family

  xfrm: Check if_id in xfrm_migrate
  xfrm: Fix xfrm migrate issues when address family changes
