Fix clang-format 22 alignment in loadavg macros, tmpfs setattr
mask wrap, and record-lock utest defines so the format CI passes.
[dfs][utest] Add POSIX record-lock coverage2026-08-30T12:49:24Zbernardbernard.xiong@gmail.com2026-08-23T02:13:24Zurn:sha1:3ac2b39d2585e5728b00f9d645403972d2ea5563
Cover positive/negative l_len, overlapping GETLK conflicts,
interrupted F_SETLKW, split/merge, and close/dup2 lock release on
tmpfs.

Grow maps without a 256 VMA cap, skip RSS walks for maps, report
matching status text, real RSS/statm, MemAvailable after page-pool
free pages, load averages plus last PID, cumulative processes, RV32
cpuinfo, and per-character mount escaping.
[dfs][posix] Fix EFAULT, tmpfs setattr, and chmod bits2026-08-30T12:49:24Zbernardbernard.xiong@gmail.com2026-08-23T02:13:09Zurn:sha1:06e45356f839bfd948ad5c07b13dad6a984986a8
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][procfs] Add Linux-compatible process and system files2026-08-30T12:49:24Zbernardbernard.xiong@gmail.com2026-08-22T23:44:06Zurn:sha1:25cbe4abae05e9be46edff3966850af8a7f58515
补齐 procfs 中 cpuinfo、stat、uptime、loadavg、meminfo、mounts 和进程目录文件。
按架构和 SMP 配置隔离仅在对应平台有效的字段，避免非 AArch64/非 SMP 构建告警。
[dfs][posix] Add record locks, fchmod, and tmpfs metadata2026-08-30T12:49:24Zbernardbernard.xiong@gmail.com2026-08-22T23:43:50Zurn:sha1:f02a869318c9df28ec2eab41f1a58795dc8a3f1b
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。

* 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.[fix][dfs] 增加文件系统操作的类型检查，防止类型不匹配导致数据结构不一致引发的异常2026-08-06T03:18:51Zangryprotonangryproton@outlook.com2026-08-04T15:12:09Zurn:sha1:2f7a2299f61b59d5cf00426dac0d248dce9beb4c
