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

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.

POSIX.1 says:
> read() attempts to read up to count bytes from file descriptor fd
> into the buffer starting at buf.
On the other hand, for rt_device_read, the `@size` is defined as the
number of unit (block size for blk device, otherwise one byte).
Changes:
- Transferred unit size from POSIX R/W(in bytes) to rt_device_R/W during
request of file R/W operations.

The mode permissions for character, block, and pipe devices were
previously set to 0777, which is overly permissive and not in line
with standard practice. This change reduces the permissions to 0666,
restricting execute permissions while still allowing read/write access.
Changes:
- Adjusted permissions for character/block/pipe devices from 0777 to 0666.

This change addresses a potential out-of-memory access issue in the
devfs filesystem component. The issue arises when the `rt_malloc`
function allocates memory for a path string without accounting for
the null terminator, leading to undefined behavior.
As the manual documented:
> DESCRIPTION
> The strlen() function calculates the length of the string pointed to
> by s, excluding the terminating null byte ('\0').
To fix this, the memory allocation size was increased by one byte
to ensure space for the null terminator. This prevents potential
out-of-memory access and ensures proper string termination.
