glebius 2005-11-25 14:26:40 UTC FreeBSD src repository Modified files: (Branch: RELENG_6) sys/netgraph ng_socket.c Log: MFC 1.70: Fix several races between socket closure and node/hook destruction: - Backout 1.62, since it doesn't fix all possible problems. - Upon node creation, put an additional reference on node. - Add a mutex and refcounter to struct ngsock. Netgraph node, control socket and data socket all count as references. - Introduce ng_socket_free_priv() which removes one reference from ngsock, and frees it when all references has gone. - No direct pointers between pcbs and node, all pointing is done via struct ngsock and protected with mutex. Revision Changes Path 1.67.2.4 +100 -80 src/sys/netgraph/ng_socket.c
