rwatson 2009-06-24 14:29:40 UTC FreeBSD src repository Modified files: sys/netinet ip_input.c Log: SVN rev 194835 on 2009-06-24 14:29:40Z by rwatson Clear 'ia' after iterating if_addrhead for unicast address matching: since 'ifa' was used as the TAILQ_FOREACH() iterator argument, and 'ia' was just derived form it, it could be left non-NULL which confused later conditional freeing code. This could cause kernel panics if multicast IP packets were received. [1] Call 'struct in_ifaddr *' in ip_rtaddr() 'ia', not 'ifa' in keeping with normal conventions. When 'ipstealth' is enabled returns from ip_input early, properly release the 'ia' reference. Reported by: lstewart, sam [1] MFC after: 6 weeks Revision Changes Path 1.366 +9 -6 src/sys/netinet/ip_input.c
