-Subject: [PATCH 3/4] xfrm: Fix stack-out-of-bounds read on socket policy
- lookup.
-
-When we do tunnel or beet mode, we pass saddr and daddr from the
-template to xfrm_state_find(), this is ok. On transport mode,
-we pass the addresses from the flowi, assuming that the IP
-addresses (and address family) don't change during transformation.
-This assumption is wrong in the IPv4 mapped IPv6 case, packet
-is IPv4 and template is IPv6.
-
-Fix this by catching address family missmatches of the policy
-and the flow already before we do the lookup.

-Subject: [PATCH 4/4] drm/i915/edp: Only use the alternate fixed mode if it's
- asked for
-
-In commit dc911f5bd8aa ("drm/i915/edp: Allow alternate fixed mode for
-eDP if available."), the patch allows for the use of an alternate fixed
-mode if it is available, but the patch was not ensuring that the only
-time the alternate mode is used is when it is specifically requested.
-This patch adds an additional comparison to intel_edp_compare_alt_mode
-to ensure that we only use the alternate mode if it is directly
-requested.
-
-Fixes: dc911f5bd8aac ("Allow alternate fixed mode for eDP if available.")
