* Several changes breaking netgraph module ABI collected together:Alexander Motin2008-04-151-23/+15
| | | | | | | | | | | | | | | | | | | | | | | | | - reorder structures fields (XX_refs) a bit to group fields modified same time together. According to my tests it gives up to 10% SMP performance benefit on real workload due to reduced inter-CPU cache trashing. - change q_flags from long to int as long is not really needed there and it's usage with atomics is argued by some people. - move NGF_WORKQ flag into the separate field q_flags2 as it protected by queue mutex instead of node writer protection used by the rest of flags. - move nd_work queue entry to ng_queue structure to which it is more related and make it STAILQ instead of TAILQ as now it is a classic FIFO. - remove q_node pointer from ng_queue structure as it is not really needed. - reimplement item queue using STAILQ instead of own equal implementation. As soon as BT subsystem has own item queues using ng_item.el_next update it also. - change depth field in ng_item from uintptr_t to u_int. It was made uintptr_t to keep ABI compatibility.

* soreceive_generic(), and sopoll_generic(). Add new functions sosend(),Robert Watson2006-07-241-5/+4
| | | | | | | | | | | | | | | | | | | soreceive(), and sopoll(), which are wrappers for pru_sosend, pru_soreceive, and pru_sopoll, and are now used univerally by socket consumers rather than either directly invoking the old so*() functions or directly invoking the protocol switch method (about an even split prior to this commit). This completes an architectural change that was begun in 1996 to permit protocols to provide substitute implementations, as now used by UDP. Consumers now uniformly invoke sosend(), soreceive(), and sopoll() to perform these operations on sockets -- in particular, distributed file systems and socket system calls.

* Change semantics of socket close and detach. Add a new protocol switchRobert Watson2006-07-218-5/+39
| | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | use this ioctl to obtain the list of HCI nodes. User-space application is expected to preallocate 'ng_btsocket_hci_raw_node_list_names' structure and set limit in 'num_nodes' field. The 'nodes' field should be allocated as well and it should have space for at least 'num_nodes' elements. The SIOC_HCI_RAW_NODE_LIST_NAMES should be issued on bound raw HCI socket. It does not really really matter what HCI name the socket is bound to, as long as it is not empty. MFC after: 1 week Notes: svn path=/head/; revision=158672
* Chance protocol switch method pru_detach() so that it returns voidRobert Watson2006-04-017-39/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Notes: svn path=/head/; revision=157370

| | | | | | | | | | | | | | | | | 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 Notes: svn path=/head/; revision=157366

* Push the assignment of a new or updated so_qlimit from solisten()Robert Watson2005-10-304-6/+6
| | | | | | | | | | | | | | | | | following the protocol pru_listen() call to solisten_proto(), so that it occurs under the socket lock acquisition that also sets SO_ACCEPTCONN. This requires passing the new backlog parameter to the protocol, which also allows the protocol to be aware of changes in queue limit should it wish to do something about the new queue limit. This continues a move towards the socket layer acting as a library for the protocol. Bump __FreeBSD_version due to a change in the in-kernel protocol interface. This change has been tested with IPv4 and UNIX domain sockets, but not other protocols. Notes: svn path=/head/; revision=151888
