Add AF_UNIX sockets implementation (#11681)

2026-08-17T09:15:34Z

* components/dfs: support unix socket nodes AF_UNIX pathname binding and descriptor passing require DFSv2 socket nodes and retained open file descriptions across fd tables. Add socket-node creation for tmpfs and devtmpfs, fd reference helpers, and socket F_SETFL forwarding. Impact: DFSv2 socket nodes and descriptor reference handling. Validation: git diff --cached --check. * components/net/sal: support local protocol providers Local IPC protocol families do not have a backing network device. Store the selected provider in each SAL socket and add a local provider registry while preserving netdev checks for Internet sockets. Handle DFSv2 close semantics, socketpair flags, and MSG_CTRUNC for AF_UNIX integration. Impact: SAL protocol dispatch for all socket families. Validation: git diff --cached --check. * components/lwp: support unix socket messages Musl AF_UNIX addresses and ancillary data require explicit ABI and user-memory conversion at the LWP syscall boundary. Add the musl msghdr layout, bounded address and message copying, control-message level conversion, and MSG_CTRUNC translation. Correct receive buffer allocation and copy lengths while handling messages. Impact: LWP socket syscalls when SAL is enabled. Validation: git diff --cached --check. * components/net/af_unix: add local sockets Add an opt-in AF_UNIX provider for pathname-based local IPC without a synthetic network device. Support datagram and stream sockets, blocking and nonblocking I/O, timeouts, poll, socketpair, and SCM_RIGHTS descriptor passing. Include bounded Kconfig settings, component documentation, and utest coverage. Impact: enabled only by RT_USING_AF_UNIX and requires SAL POSIX with DFSv2. Validation: git diff --cached --check. * Fix AF_UNIX CI checks Apply the repository clang-format rules to the affected source lines. Suppress the cppcheck false positive for the devtmpfs list iterator. No functional behavior is changed. * components/lwp: preserve NULL optional msghdr buffers When msg_name or msg_control is NULL, keep the kernel pointer NULL instead of substituting an uninitialized buffer. Reject a NULL control buffer with a nonzero length as EFAULT. Impact: LWP sendmsg/recvmsg conversion on MMU targets. Validation: git diff --cached --check. * components/net/af_unix: fix poll UAF, namespace leak, and SCM_RIGHTS cycles Poll only the local wait queue and wake writers from the receiver. Free namespace entries on detach, and reject AF_UNIX descriptors in SCM_RIGHTS until cycle collection exists. Impact: AF_UNIX poll, bind lifetime, and descriptor passing. Validation: git diff --cached --check. * components/dfs: add DFSv2 AF_UNIX utest suite Add opt-in tests under dfs/utest/v2/af_unix for socket nodes, IPC, poll peer-close, namespace cleanup, and SCM_RIGHTS rejection. Sources are built only when RT_UTEST_TC_USING_DFS_V2_AF_UNIX and the selected test groups are enabled. Impact: DFS utest menu and build; no production AF_UNIX behavior change. Validation: git diff --cached --check.

doxygen: add prefix for groups (#9991)

2025-02-15T04:15:19Z

* doxygen: add prefix for groups Add "group_" prefix to doxygen group names. This makes it easier to grep with group name later. This patch only modifies the groups defined in the pathes of INPUT of documentation/Doxyfile: INPUT = . \ ../src \ ../include \ ../components/finsh \ ../components/drivers/include/drivers \ ../components/drivers/clk \ ../components/dfs/dfs_v2/src \ ../components/dfs/dfs_v2/include Other groups are not touched. Signed-off-by: Chen Wang * ci: fixed error report when run file_check.py Such as: - "please delete extra space at the end of this line." - "the RT-Thread error code should return negative value. e.g. return -RT_ERROR" Signed-off-by: Chen Wang --------- Signed-off-by: Chen Wang
