The run.sh script explicitly checks that CONFIG_MODULES is disabled.
By default, this config option is enabled. Explicitly disable it to be
able to run the RDS tests.
Note that writing '# CONFIG_(...) is not set' is usually recommended to
disable an option in the .config, but it looks like selftests usually
set 'CONFIG_(...)=n', which looks clearer.

This patch adds support for testing rds rdma over ROCE. A new
-r flag is added to config.sh which enables the required kernel
configs for rdma. We also add a -T flag to run.sh, which takes
a transport option, tcp or rdma. The rdma option will check to
ensure the proper configs have been enabled. The flag is then
passed to test.py, which will run the test over the specified
transport(s)

This patch adds a teardown_tcp() helper that removes net0/net1.
The cmd calls here use fail=False so they can be called from
completed or partially-setup states on error. Also call
teardown_tcp() at the top of setup_tcp() so a previous
interrupted run does not leave net0/net1 lingering and break a
subsequent ip netns add. Register teardown_tcp() with atexit
before setup_tcp() is invoked.
Likewise, we can simpliy stop_pcaps() handling by registering it
with atexit instead of calling it from the signal handler.
atexit handlers run on any exit path - normal completion, raised
exception, and sys.exit() from the timeout signal handler. This
guarantees cleanup are called without further wrapping the test
body in a try/finally blocks.
atexit LIFO ordering keeps stop_pcaps before teardown_tcp so
tcpdumps are killed cleanly before their namespaces go away.
This is a preparatory cleanup for the upcoming ROCE patch which
will also register a teardown_rdma() alongside teardown_tcp()

Sockets created by child processes in netns_socket may raise
exceptions that are currently not handled by the parent. If for
example a namespace didn't exist or the rds module didn't load. Because
these exceptions occur with in a child thread, the child thread exits,
but the parent does not check the return status.
Further, allowing the child processes to quietly raise exceptions
will cause problems later if the parent registers clean up functions
with atexit. Since the child processes inherit the parents handlers,
they may prematurely call the parents cleanup routines without the
parent being aware.
Fix this by all catching exceptions raised by the child processes.
Child errors surface as a non-zero exit status, which are then
properly raised in the parent process.

Using the format specifier +%s%3N with GNU date is honoured, and only
prints 3 digits of the nanoseconds portion of the seconds since epoch,
which corresponds to the milliseconds.
The uutils implementation of date currently does not honour this, and
always prints all 9 digits. This is a known issue [1], but can be worked
around by adapting this test to use nanoseconds instead of microseconds,
and then divide it by 1e6.
This fix is similar to what has been done on systemd side [2], and it is
needed to run the selftests on Ubuntu 26.04, containing uutils 0.8.0.
Note that the Fixes tag is there even if this patch doesn't fix an issue
in the kernel selftests, but it is useful for those using uutils 0.8.0.

Add test_pop_vlan() to verify OVS kernel datapath pop_vlan action
correctly strips 802.1Q VLAN tags from frames.
Test structure:
- Baseline: untagged forwarding validates basic connectivity.
- Negative: forward without pop_vlan, tagged frame is invisible
to ns2 (no VLAN sub-interface), ping fails.
- Positive: pop_vlan strips tag on forward path, push_vlan
restores tag on return path, ping succeeds.
Use static ARP entries to avoid VLAN-tagged ARP complexity.
Rely on ping success/failure for verification -- no tcpdump or
pcap files needed.

Add VLAN TCI formatting and parsing support to ovs-dpctl.py:
- Add _vlan_dpstr() to decompose TCI into vid/pcp/cfi fields,
with raw tci=0x%04x fallback when cfi=0 for round-trip safety.
- Add _parse_vlan_from_flowstr() boundary check for missing ')'.
- Add encap_ovskey subclass restricting nla_map to L2-L4 attributes
(slots 0-21) that appear inside 802.1Q ENCAP, with metadata
attributes set to "none".
- Check encap parse() return value for unrecognized trailing content.
- Support callable format functions in dpstr() output.
- Change OVS_KEY_ATTR_VLAN type from uint16 to be16 to match the
kernel __be16 wire format; uint16 decodes in host byte order,
which gives wrong values on little-endian architectures.
- Change OVS_KEY_ATTR_ENCAP type from none to encap_ovskey to
enable recursive parsing of 802.1Q encapsulated flow keys.
- Add push_vlan action class with fields matching kernel struct
ovs_action_push_vlan (vlan_tpid, vlan_tci as network-order u16).
- Add push_vlan dpstr format and parse with range validation
(vid 0-4095, pcp 0-7, tpid 0-0xFFFF) and CFI forced to 1.

Add tests to validate the neigh_forward_grat bridge option for selective
forwarding of gratuitous neighbor announcements.
The tests verify per-port and per-VLAN control of gratuitous neighbor
announcement forwarding for both IPv4 (gratuitous ARP) and IPv6
(unsolicited NA):
- When neigh_suppress is enabled with neigh_forward_grat off (default),
gratuitous announcements are suppressed
- When neigh_forward_grat is enabled, gratuitous announcements are
forwarded while regular neighbor discovery remains suppressed
For IPv4, use arping to send gratuitous ARP packets. For IPv6, use
mausezahn to craft unsolicited Neighbor Advertisement packets.
For the per-port tests, the IPv4 test exercises the ip link interface,
while the IPv6 test exercises the bridge link interface.
The per-VLAN tests use the bridge interface throughout, as per-VLAN
attributes are only accessible via 'bridge vlan'.

These limits have been recently updated, from 8 to:
- 64 for the subflows and accepted add_addr
- 255 for the MPTCP endpoints
These modifications validate the new limits, but are also compatible
with the previous ones, to be able to continue to validate stable kernel
using the last version of the selftests. That's why new variables are

The limits have been recently increased, it is required to validate that
having 64 subflows is allowed.
Here, both the client and the server have 8 network interfaces. The
server has 8 endpoints marked as 'signal' to announce all its v4
addresses. The client also has 8 endpoints, but marked as 'subflow' and
'fullmesh' in order to create 8 subflows to each address announced by
the server. This means 63 additional subflows will be created after the
initial one.
If it is not possible to increase the limits to 64, it means an older
kernel version is being used, and the test is skipped.

By default, 4 network interfaces are created per subtest in a dedicated
net namespace. Each netns has a dedicated pair of v4 and v6 addresses.
Future tests will need more.
Simply always creating more network interfaces per test will increase
the execution time for all other tests, for no other benefits. So now it
is possible to change this number only when needed, by setting ifaces_nr
when calling 'reset' and 'init_shapers', e.g.
ifaces_nr=8 reset "Subtest title"
ifaces_nr=8 init_shapers
Note that it might also be interesting to decrease the default value to
2 to reduce the setup time, especially when a debug kernel config is
being used.

A race in stop_pcaps is possible if the test completes and then
times out while waiting for the tcpdump process to exit. The
signal handler may fire again and needlessly call stop_pcap a
second time. Fix this by disabling the alarm after normal
test completion.
Also if there are no tcpdump processes to wait on, stop_pcaps can
just exit. This avoids misleading prints when there are no procs
to collect dumps from.

Apply two cleanups suggested by Stanislav and bobby on the original
selftest series:
- Reorder local variable declarations into reverse christmas-tree
order (longest line first). Because that ordering puts socklen_t
optlen before the variable whose size it stores, the
"optlen = sizeof(...)" initializer is moved out of the declaration
to a plain assignment in the test body, as Stanislav suggested.
- Add ASSERT_EQ(optlen, ...) on every error path so the value the
kernel writes back to the userspace optlen is pinned down even
when the syscall returns -1. With do_sock_getsockopt() now writing
opt->optlen back to userspace unconditionally, asserting that the
netlink/vsock error paths leave the original input length untouched
guards against future regressions.
Bobby Eshleman pointed out that
SO_VM_SOCKETS_CONNECT_TIMEOUT_NEW/OLD return a sock_timeval-shaped
payload (16 bytes on 64-bit), which is wider than the u64 case
already covered. Add four tests that exercise this path:
- connect_timeout_new_exact exact-size buffer
- connect_timeout_new_oversize_clamped oversize buffer, clamped
- connect_timeout_new_undersize undersize -> -EINVAL, optlen
untouched
- connect_timeout_old_exact exact-size buffer for OLD optname

Using '${?}' inside the if-statement to check the returned value from
the command that was evaluated as part of the if-statement is not
correct: here, '${?}' will be linked to the previous instruction, not
the one that is expected here (${cmd}).
Instead, simply mark the error, except if an error is expected. If
that's the case, 1 can be passed as the 4th argument of this helper.
Three checks from pm_netlink.sh expect an error.
While at it, improve the error message when the command unexpectedly
fails or succeeds.
Note that we could expect a specific returned value, but the checks
currently expecting an error can be used with 'ip mptcp' or 'pm_nl_ctl',
and these two tools don't return the same error code.

This patch updates the rds selftests output to be TAP compliant.
Use ksft_pr() to mark debug output with a leading '# ' so that TAP
parsers treat it as commentary, and convert all informational print()
calls to use ksft_pr(). sys.exit(0) is changed to os._exit(0) to
avoid duplicate prints from the buffered TAP output. The console
output from the tcpdump subprocess is silenced, and the gcov console
output is redirected to a gcovr.log.
Finally adjust the exit path so that the hash check loop sets a
return code instead exiting directly. Then print the TAP results
and totals lines before exiting.

debugfs is not mounted automatically in a virtme-ng guest, so the
gcov data copy from /sys/kernel/debug/gcov/ silently finds nothing
depending on whether debugfs is mounted by default on the host OS.
Fix this by mounting debugfs in run.sh before copying the gcda
files.
Finally when invoked through the kselftest runner, the working
directory is the test directory rather than the kernel source root.
gcovr defaults --root to the current working directory, which causes
it to filter out all coverage data for files under net/rds/ since
they are not under the test directory. Fix this by passing --root
to gcovr explicitly.

The timeout signal handler for the rds selftests currently just
exits when the time limit is exceeded, and forgets to stop the
network dumps. Fix this by hoisting the tcpdump terminate commands
into a helper function, and call it from the signal handler before
exiting
Bound proc.wait() with a timeout (and fall back to proc.kill())
so an unresponsive tcpdump cannot hang the timeout path itself.
We also pop() tcpdump_procs as we iterate, so stop_pcaps() is safe
to call from both the normal cleanup path and the signal handler,
since the second invocation simply has nothing to do

This patch removes the initial tmp tcpdumps and instead saves

This patch modifies rds selftests to use the environment variable
SUDO_USER for tcpdumps if it is set. This is needed to avoid chown
operations on the vng 9pfs which is not supported. Passing a user
listed in sudoers avoids the tcpdump privilege drop which may
otherwise create empty pcaps

the folder specified in RDS_LOG_DIR. If RDS_LOG_DIR is unset,

This patch fixes a few pylint errors in test.py. Remove unused exception
variables from except blocks, and disable warnings for imports that cannot
appear at the start of the module. Also disable warnings for the
tcpdump processes. The suggestion to use a with block does not apply
here since the process needs to outlive the parent to collect the dumps.
Lastly add the module docstring at the top of the module.

The 400s time out was originally developed under a leaner
kernel config that booted much faster than a default config.
Boot up is included as part of the over all test runtime, as
well as any log collection done when the test is complete.
A slower config combined with the gcov enabled test means
we'll need more time to accommodate the boot up and log
collection. So, bump time out to 800s.

In preparation for extending to pacing hardware offload, convert the
so_txtime.sh test to a drv-net test that can be run against netdevsim
and real hardware.
Also update so_txtime.c to not exit on first failure, but run to
completion and report exit code there. This helps with debugging
unexpected results, especially when processing multiple packets,
as happens in the "reverse_order" testcase.

----
v6 -> v7
- update test to use new argument expect_fail
- v6 received Reviewed-by, but dropped due to above (minor) change
v5 -> v6
- fix order in tools/testing/selftests/drivers/net/config
v4 -> v5
- move qdisc setup/restore into each test
- add tc to utils.py (separate patch)
- test expected failure (separate patch)
- fix pylint
- convert fail to pass for timing errors if KSFT_MACHINE_SLOW
(cmd does not special case KSFT_SKIP process returncode yet)
Responses to sashiko review
- The test converts per packet failure to errors, to continue
testing other packets, but other error() cases are not in scope.
- The test starts sender and receiver at an absolute future time,
like the original test. This assumes ~msec scale sync'ed clocks.
- The tc qdisc replace command works fine with noqueue. Tested
manually.
v3 -> v4
- restore original qdisc after test
- drop unnecessary underscore in tap test names
v2 -> v3
- Makefile: so_txtime from YNL_GEN_FILES to TEST_GEN_FILES (Sashiko, NIPA)
v1 -> v2
- move so_txtime.c for net/lib to drivers/net (Jakub)
- fix drivers/net/config order (Jakub)
- detect passing when failure is expected (Jakub, Sashiko)
- pass pylint --disable=R (Jakub)
- only call ksft_run once (Jakub)
- do not sleep if waiting time is negative (Sashiko)
- add \n when converting error() to fprintf() (Sashiko)
- 4 space indentation, instead of 2 space
- increase sync delay from 100 to 200ms, to fix rare vng flakes

Add a wrapper similar to existing ip, ethtool, ... commands.
Tc takes a slightly different syntax. Account for that.
The first user is the next patch in this series, converting so_txtime
to drv-net. Pacing offload is supported by selected qdiscs only.

Support negative tests, where cmd raises an exception if the command
succeeded.
Add optional argument expect_fail to cmd and bkg. Where fail fails the
test on unexpected error, expect_fail fails it on unexpected success.
Both fail on negative return code. Python subprocess may set a
negative return code on process crash or timeout. Those are never
anticipated failures.

There were a few issues found with the tunnel vport types around the
vport destruction code. Add some basic tests, so at least we know that
they can be properly added and removed without obvious issues.
The test creates OVS datapath, adds a non-LWT tunnel port, makes sure
they are created, and then removes the datapath and waits for all the
ports to be gone.
The dpctl script had a few bugs in the none-lwt tunnel creation code,
so fixing them as well to make the testing possible:
- The type of the --lwt option changed in order to properly disable it.
- Removed byte order conversion for the port numbers, as the value
supposed to be in the host order.
- Added missing 'gre' choice for the tunnel type.

Add a single kselftest covering the proto_ops getsockopt_iter
conversions for AF_NETLINK and AF_VSOCK, using one fixture per protocol:
netlink:
NETLINK_PKTINFO covers the flag-style int path (exact size, oversize
clamp, undersize -EINVAL); NETLINK_LIST_MEMBERSHIPS covers the
size-discovery path that always reports the required buffer length back
via optlen, even when the user buffer is too small to receive any group
bits.
vsock:
SO_VM_SOCKETS_BUFFER_SIZE covers the u64 path (exact size, oversize
clamp, undersize -EINVAL).
Each fixture also exercises an unknown optname and a bogus level so
the returned-length / errno semantics preserved by the sockopt_t
conversion are pinned down.
