* 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.format: format sal socket code2025-10-04T01:03:25ZYuqiang Wangyifang.wangyq@foxmail.com2025-09-30T03:18:02Zurn:sha1:2e45b9b340d99f9c8348e6b6df62fae5845ebc8cfeat:[sal][utest] added test cases for the sal api2025-10-04T01:03:25ZYuqiang Wangyifang.wangyq@foxmail.com2025-09-30T03:16:28Zurn:sha1:326e65f6ed30ffd420380f374b5692f730ad20cf[fix][ci]Fixed CI compilation failure in sal/src/sal_socket.c2025-09-09T08:42:16ZRbb666zhangbingru@rt-thread.com2025-09-09T07:19:33Zurn:sha1:b525d2c535470f010ea14ecb637b3da5395a6ff5[components][sal]add netdev ifindex feature2024-10-11T04:10:21Zzms12345685141075+zmshahaha@users.noreply.github.com2024-10-11T04:10:21Zurn:sha1:9a010bb71b278afb3fcb4b98f28668b598f01369optimize sal_bind2024-09-19T13:15:52Zzhao maoshengzmshahaha@gmail.com2024-09-10T08:21:19Zurn:sha1:992e79a0f8975657bf741d95d1faf4ab5c6f3ee3[components][sal]delay getting sal_proto_family in sal_ioctlsocket2024-09-14T17:52:40Zzms12345685141075+zmshahaha@users.noreply.github.com2024-09-14T17:52:40Zurn:sha1:379aece6dc0ba2bc74c3e6548010df8017cf5359[component][sal]delete netdev_lo2024-09-14T05:49:25Zzms12345685141075+zmshahaha@users.noreply.github.com2024-09-14T05:49:25Zurn:sha1:accd616e17ab5cb19a7576a57640ba43785fe123
