* 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:sha1:2f7a2299f61b59d5cf00426dac0d248dce9beb4ccomponents/dfs: unify vnode lock names2026-07-31T07:13:53ZBernard Xiongbernard.xiong@gmail.com2026-07-31T07:13:53Zurn:sha1:2b01936f113fe050d8eca5d9e5e8c4fc724889b7[fix][dfs] 修正 elmfat mkfs 中 f_mount 的错误传参2026-07-23T03:57:10Zangryprotonangryproton@outlook.com2026-07-21T14:57:46Zurn:sha1:f19da943aa905d9be49451e8cbad1a3fae0248b8[fix][tmpfs]修正 getdents 中文件类型错误的判断变量2026-07-20T02:18:14Zangryprotonangryproton@outlook.com2026-07-15T16:11:18Zurn:sha1:560fa880ff7996a0aa4d377c3ac211176089fca8[fix][dfs] elmfat磁盘操作设备指针判空2026-07-15T08:42:15Zangryprotonangryproton@outlook.com2026-07-13T14:36:25Zurn:sha1:997de9433af42aacb1988489ccb08b6688f440cc[chg][dfs]Clean up comments in dfs_elm_free_vnode2026-07-13T02:54:07Z与非熊38059101+Unbear-Hz@users.noreply.github.com2026-07-12T09:19:07Zurn:sha1:63b4a7fcc2971b2f3001853da9fe33207dd80906
