[PATCH 0/2] af_key: Fix for sadb_key memcpy read overrun

As found by syzbot, af_key does not properly validate the key length in
sadb_key messages from userspace.  This can result in copying from beyond
the end of the sadb_key part of the message, or indeed beyond the end of
the entire packet.

Kevin Easton (2):
  af_key: Use DIV_ROUND_UP() instead of open-coded equivalent
  af_key: Always verify length of provided sadb_key
