[style] Align clang-format for procfs and tmpfs

2026-08-30T12:49:24Z

Fix clang-format 22 alignment in loadavg macros, tmpfs setattr mask wrap, and record-lock utest defines so the format CI passes.

[dfs][posix] Fix EFAULT, tmpfs setattr, and chmod bits

2026-08-30T12:49:24Z

NULL read/write buffers now return -EFAULT. tmpfs setattr uses the vnode-backed object after unlink, keeps S_ISUID/S_ISGID/S_ISVTX, and the tmpfs utest checks ENAMETOOLONG plus post-unlink fchmod.

[dfs][posix] Add record locks, fchmod, and tmpfs metadata

2026-08-30T12:49:24Z

为 DFS v2 增加 POSIX 记录锁、fchmod，以及 tmpfs 的权限和时间元数据。进程退出时通过 dfs_fdtable_drop_fd 释放文件描述符和记录锁。

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.
