Merge r185928 from head to stable/7:

2009-02-06T12:20:08Z

Add missing "goto set_head" for SO_IPX_CHECKSUM; otherwise we fall through to the SO_HEADERS_ON_OUTPUT case and set that instead. Found with: Coverity Prevent(tm) Coverity ID: 3988

Remove IPX over IP tunneling support, which allows IPX routing over IP

tunnels, and was not MPSAFE. The code can be easily restored in the event that someone with an IPX over IP tunnel configuration can work with me to test patches. This removes one of five remaining consumers of NET_NEEDS_GIANT. Approved by: re (kensmith)

Use ANSI C function declarations throughout netipx.

Remove 'register' use.

Reduce network stack oddness: implement .pru_sockaddr and .pru_peeraddr

2007-05-11T10:20:51Z

protocol entry points using functions named proto_getsockaddr and proto_getpeeraddr rather than proto_setsockaddr and proto_setpeeraddr. While it's true that sockaddrs are allocated and set, the net effect is to retrieve (get) the socket address or peer address from a socket, not set it, so align names to that intent.

Change semantics of socket close and detach. Add a new protocol switch

2006-07-21T17:11:15Z

function, pru_close, to notify protocols that the file descriptor or other consumer of a socket is closing the socket. pru_abort is now a notification of close also, and no longer detaches. pru_detach is no longer used to notify of close, and will be called during socket tear-down by sofree() when all references to a socket evaporate after an earlier call to abort or close the socket. This means detach is now an unconditional teardown of a socket, whereas previously sockets could persist after detach of the protocol retained a reference. This faciliates sharing mutexes between layers of the network stack as the mutex is required during the checking and removal of references at the head of sofree(). With this change, pru_detach can now assume that the mutex will no longer be required by the socket layer after completion, whereas before this was not necessarily true. Reviewed by: gnn

Chance protocol switch method pru_detach() so that it returns void

2006-04-01T15:42:02Z

rather than an error. Detaches do not "fail", they other occur or the protocol flags SS_PROTOREF to take ownership of the socket. soclose() no longer looks at so_pcb to see if it's NULL, relying entirely on the protocol to decide whether it's time to free the socket or not using SS_PROTOREF. so_pcb is now entirely owned and managed by the protocol code. Likewise, no longer test so_pcb in other socket functions, such as soreceive(), which have no business digging into protocol internals. Protocol detach routines no longer try to free the socket on detach, this is performed in the socket code if the protocol permits it. In rts_detach(), no longer test for rp != NULL in detach, and likewise in other protocols that don't permit a NULL so_pcb, reduce the incidence of testing for it during detach. netinet and netinet6 are not fully updated to this change, which will be in an upcoming commit. In their current state they may leak memory or panic. MFC after: 3 months

Change protocol switch pru_abort() API so that it returns void rather

than an int, as an error here is not meaningful. Modify soabort() to unconditionally free the socket on the return of pru_abort(), and modify most protocols to no longer conditionally free the socket, since the caller will do this. This commit likely leaves parts of netinet and netinet6 in a situation where they may panic or leak memory, as they have not are not fully updated by this commit. This will be corrected shortly in followup commits to these components. MFC after: 3 months
