Hi everybody, The following commands lead the 9.0-CURRENT kernel to crash:
[r...@freebsd /usr/home/int0dh]# ngctl Available commands: config get or set configuration of node at <path> connect Connects hook <peerhook> of the node at <relpath> to <hook> debug Get/set debugging verbosity level dot Produce a GraphViz (.dot) of the entire netgraph. help Show command summary or get more help on a specific command list Show information about all nodes mkpeer Create and connect a new node to the node at "path" msg Send a netgraph control message to the node at "path" name Assign name <name> to the node at <path> read Read and execute commands from a file rmhook Disconnect hook "hook" of the node at "path" show Show information about the node at <path> shutdown Shutdown the node at <path> status Get human readable status information from the node at <path> types Show information about all installed node types write Send a data packet down the hook named by "hook". quit Exit program + mkpeer ksocket myhook inet/stream/tcp + msg .:myhook connect inet/127.0.0.1:22 After last command the kernel panics. Any listening TCP port can be used instead of 22. The panic occurs here (sys/kern/uipc_sockbuf.c): int sbappendaddr_locked(struct sockbuf *sb, const struct sockaddr *asa, struct mbuf *m0, struct mbuf *control) { struct mbuf *m, *n, *nlast; int space = asa->sa_len; SOCKBUF_LOCK_ASSERT(sb); if (m0 && (m0->m_flags & M_PKTHDR) == 0) { panic("sbappendaddr_locked"); } I`ve tried with the custom kernel only, but I think that issue can be reproduced with GENERIC too. _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
