Modified files:
sys/netgraph ng_socket.c
Log:
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.
