[components][lwp] Remove terminal/ from global CPPPATH

2026-09-03T01:20:30Z

The terminal subsystem's own headers (terminal.h, tty_config.h, ...) are resolved by the compiler's quoted-include directory lookup for sources inside components/lwp/terminal; nothing else depends on the path. Stop polluting the global CPPPATH with this internal directory, following the convention discussed in #10980.

[dfs][procfs] Fix Linux-compatible procfs fields

2026-08-30T12:49:24Z

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.

[libc][posix] Fix epoll waiters and LWP syscall copies

2026-08-30T12:49:24Z

修复 epoll waiter 生命周期，避免等待队列节点在回调后失效。整理 LWP POSIX syscall 的用户空间拷贝和错误返回路径。

[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。

[kernel][ipc] Fix timeout wakeup ownership race

2026-08-21T08:52:01Z

Keep thread timer ownership when timer stop races with an in-flight timeout callback, and consume IPC resources only after a waiter is resumed successfully. Complete ownership cleanup in the generic and RT-Smart channel timeout callbacks. Add deterministic scheduler and LWP regressions for Event, Semaphore, Mailbox, Message Queue, sender, and receiver paths.

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.

lwp: copy timeout into kernel space in sys_select()

2026-07-22T13:50:12Z

sys_select() passed the raw user-space timeout pointer straight through to select(), unlike readfds/writefds/exceptfds which are all validated with lwp_user_accessable() and copied into kernel memory first. A malicious or buggy user thread could pass a timeout pointing at unmapped or otherwise invalid memory, which select() would then dereference directly (timeout->tv_sec / timeout->tv_usec) without any check, from kernel context. Validate and copy it into a kernel-local struct timeval the same way the fd_set arguments already are, before it reaches select(). Fixes #10298 Signed-off-by: yi chen <94xhn1@gmail.com>

fix: move tty_ptmx regression test to utest framework

2026-06-16T07:43:44Z

The previous commit placed the test in a new top-level tests/ directory that does not exist in the RT-Thread repo structure and used the external check library. Move the test to examples/utest/testcases/lwp/ and rewrite it using RT-Thread's native utest framework, add a Kconfig symbol (RT_UTEST_LWP_TTY_PTMX), and wire it into Kconfig.utestcases.
