bz 2008-11-06 12:33:33 UTC FreeBSD src repository Modified files: sys/netinet tcp_input.c Log: SVN rev 184720 on 2008-11-06 12:33:33Z by bz Fix a bug introduced with r182851 splitting tcp_mss() into tcp_mss() and tcp_mss_update() so that tcp_mtudisc() could re-use the same code. In case we return early and got a metricptr to pass the hostcache info back to the caller we need to initialize the data to a defined state (zero it) as tcp_hc_get() would do if there was no hit. Without that the caller would check on random stack garbage which could lead to undefined results. This only affected tcp_mss() if there was no routing entry for the peer, tcp_mtudisc() was not affected. MFC after: 2 months (along with r182851) Revision Changes Path 1.388 +9 -1 src/sys/netinet/tcp_input.c
