rt_thread_delay(0)
The 'index == times' condition in the delay_tick calculation is never true,
so the delay was still applied after the last ping, contrary to the comment.
Skip the delay on the final ping by checking 'index != times - 1'.
Also only call rt_thread_delay() when delay_tick > 0, since passing 0
returns -RT_EINVAL.

netdev_cmd_ping() computed avg_time / received before checking that any
reply arrived. When every request times out, received is 0 and the
integer division traps (SIGFPE on the simulator, a fault on Cortex-M),
taking the shell thread down. Only compute the average inside the
existing received > 0 branch where it is printed.
Fixes #11852

The option loop advanced by the option length without checking the
number of bytes actually received by recvfrom(), so a malformed or
truncated DHCP packet could make the server read past the end of the
receive buffer.
Check that the option type, length and payload stay inside the received
data before reading them, and stop parsing when a requested IP option
is shorter than 4 bytes or a message type option is shorter than 1 byte.
Fixes #11323

- Kconfig: RT_USING_LWIP221 choice, RT_USING_LWIP_VER_NUM=0x20201
- SConscript for lwip-2.2.1 (acd.c, mdns split files, tftp.c)
- replay RTT patch set from lwip-2.1.2 onto 2.2.1
- import RTT ping.c and tftp_port.c (adapted to 2.2.x TFTP API)
- SAL: version-gated netconn socket accessor (callback_arg union >= 2.2.0)
- lwipopts: DHCP ACD (RFC 5227) and MEMP_NUM_SYS_TIMEOUT version gates

Verbatim upstream lwIP 2.2.1 official release (STABLE-2.2.1),
complete with apps/, test/ and Filelists.

Numeric hostnames were copied into a fixed stack buffer without a length bound.
Cache the length, reject values that cannot fit, and terminate the copy explicitly.

When sal_socket() rejects a request, DFS v2 descriptor cleanup destroys the dfs_file but leaves its separately allocated vnode behind.
Destroy the vnode before releasing the failed descriptor and add a regression test that verifies repeated failures do not consume heap.

netdev_cmd_ping 中 netdev 回退到 netdev_default 后未判空，

* 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.

Fill the mDNS domain name buffers with their array size instead of the size of the MDNS_DOMAIN_MAXLEN constant. This preserves the test intent of leaving different trailing bytes after equal names are encoded.

Use "Test" instead of "Unit Testcases" to make string shorter.
Use uppercase to make it look more eye-catching.

Many modules' utests currently don't support enabling all
tests at once. Furthermore, some modules' tests are complex,
for example due to their numerous dependencies on other
modules. This makes it nearly impossible to enable all
tests with a single global switch. Consequently, the
previously defined `RT_UTEST_USING_ALL_CASES` has lost
its original meaning.
We recommend deprecating this configuration switch. If a
module needs to enable a group of functional tests through
its own configuration, this local enable all switch should
be implemented by the module itself, and a global RTT enable
switch will no longer be provided.
If such a requirement arises in the future, we recommend
careful design, especially considering how to ensure that
turning on a single switch enables all dependencies for
all involved modules for ease of use.
