* sockets: don't malloc/free sockaddr memory on getpeername/getsocknameGleb Smirnoff2023-11-304-11/+9
| | | | | | | | | | | | | Just like it was done for accept(2) in cfb1e92912b4, use same approach for two simplier syscalls that return socket addresses. Although, these two syscalls aren't performance critical, this change generalizes some code between 3 syscalls trimming code size. Following example of accept(2), provide VNET-aware and INVARIANT-checking wrappers sopeeraddr() and sosockaddr() around protosw methods.

* sockets: don't malloc/free sockaddr memory on accept(2)Gleb Smirnoff2023-11-303-3/+3
| | | | | | | | | | | | | | Let the accept functions provide stack memory for protocols to fill it in. Generic code should provide sockaddr_storage, specialized code may provide smaller structure. While rewriting accept(2) make 'addrlen' a true in/out parameter, reporting required length in case if provided length was insufficient. Our manual page accept(2) and POSIX don't explicitly require that, but one can read the text as they do. Linux also does that. Update tests accordingly.

* protocols: init with standard SYSINIT(9) or VNET_SYSINITGleb Smirnoff2022-01-034-5/+0
| | | | | | | | | | | | | | | The historical BSD network stack loop that rolls over domains and over protocols has no advantages over more modern SYSINIT(9). While doing the sweep, split global and per-VNET initializers. Getting rid of pr_init allows to achieve several things: o Get rid of ifdef's that protect against double foo_init() when both INET and INET6 are compiled in. o Isolate initializers statically to the module they init. o Makes code easier to understand and maintain.

* sys: general adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-2711-0/+22
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. No functional change intended.

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.

* Change semantics of socket close and detach. Add a new protocol switchRobert Watson2006-07-213-0/+4
| | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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

* Make default RFCOMM session MTU match default L2CAP MTU.Maksim Yevmenkin2005-01-111-3/+3
| | | | | | | | | | | | | | | | | | | | | | | This is just a workaround for a know problem with Motorola E1000 phone. Something is wrong with the configuration of L2CAP/RFCOMM channel. Even though we set L2CAP MTU to 132 bytes (default RFCOMM MTU 127 + 5 bytes RFCOMM frame header) and the phone accepts it, the phone still sends oversized L2CAP packets. It appears that the phone wants to use bigger (667 bytes) RFCOMM frames, but it does not segment them according to the configured L2CAP MTU. The 667 bytes RFCOMM frame size corresponds to the default L2CAP MTU of 672 bytes (667 + 5 bytes RFCOMM frame header). This problem only appears if connection was initiated from the phone. I'm not sure who is at fault here, so for now just put workaround in place. Quick look at the spec did not reveal any anwser.
