Subject: [PATCH net 0/5] net: Length checks for attributes within multipath routes
Date: Thu, 30 Dec 2021 17:36:30 -0700	[thread overview]
Message-ID: <20211231003635.91219-1-dsahern@kernel.org> (raw)

Add length checks for attributes within a multipath route (attributes
within RTA_MULTIPATH). Motivated by the syzbot report in patch 1 and
then expanded to other attributes as noted by Ido.

David Ahern (5):
  ipv4: Check attribute length for RTA_GATEWAY in multipath route
  ipv4: Check attribute length for RTA_FLOW in multipath route
  ipv6: Check attribute length for RTA_GATEWAY in multipath route
  ipv6: Check attribute length for RTA_GATEWAY when deleting multipath
    route
  lwtunnel: Validate RTA_ENCAP_TYPE attribute is at least 2 bytes

 net/core/lwtunnel.c      |  4 ++++
 net/ipv4/fib_semantics.c | 49 +++++++++++++++++++++++++++++++++++-----
 net/ipv6/route.c         | 31 +++++++++++++++++++++++--
