bz 2010-01-06 16:48:59 UTC FreeBSD src repository Modified files: (Branch: RELENG_7) sys/netinet tcp_input.c Log: SVN rev 201654 on 2010-01-06 16:48:59Z by bz MFC r184720: Fix a bug introduced with r182851 (r201653 in stable/7) 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. Revision Changes Path 1.370.2.16 +9 -1 src/sys/netinet/tcp_input.c
