Rather than exit the internal map_symbols directly, put the mem-info
that does this and also lowers the reference count on the mem-info
itself otherwise the mem-info is being leaked.

[ Upstream commit 7da4d60db33cccd8f4c445ab20bba71531435ee5 ]
The maps__split_kallsyms() will split symbols to module DSOs if it comes
from a module. It also handled some unusual kernel symbols after modules
by creating new kernel maps like "[kernel].0".
But they are pseudo DSOs to have those unexpected symbols. They should
not be considered as unloaded kernel DSOs. Otherwise the dso__load()
for them will end up calling dso__load_kallsyms() and then
maps__split_kallsyms() again and again.

[ Upstream commit 2c28ee720ad14f58eb88a97ec3efe7c5c315ea5d ]
Jakub reported increased flakiness in bond_macvlan_ipvlan.sh on regular
kernel, while the tests consistently pass on a debug kernel. This suggests
a timing-sensitive issue.
To mitigate this, introduce a short sleep before each xvlan_over_bond
connectivity check. The delay helps ensure neighbor and route cache
have fully converged before verifying connectivity.
The sleep interval is kept minimal since check_connection() is invoked
nearly 100 times during the test.

[ Upstream commit ae24fc8a16b0481ea8c5acbc66453c49ec0431c4 ]
Currently, test_perf_branches_no_hw() relies on the busy loop within
test_perf_branches_common() being slow enough to allow at least one
perf event sample tick to occur before starting to tear down the
backing perf event BPF program. With a relatively small fixed
iteration count of 1,000,000, this is not guaranteed on modern fast
CPUs, resulting in the test run to subsequently fail with the
following:
bpf_testmod.ko is already unloaded.

Successfully unloaded bpf_testmod.ko.
On a modern CPU (i.e. one with a 3.5 GHz clock rate), executing 1
million increments of a volatile integer can take significantly less
than 1 millisecond. If the spin loop and detachment of the perf event
BPF program elapses before the first 1 ms sampling interval elapses,
the perf event will never end up firing. Fix this by bumping the loop
iteration counter a little within test_perf_branches_common(), along
with ensuring adding another loop termination condition which is
directly influenced by the backing perf event BPF program
executing. Notably, a concious decision was made to not adjust the
sample_freq value as that is just not a reliable way to go about
fixing the problem. It effectively still leaves the race window open.

[ Upstream commit 27746aaf1b20172f0859546c4a3e82eca459f680 ]
Gracefully skip the test_perf_branches_hw subtest on platforms that
do not support LBR or require specialized perf event attributes
to enable branch sampling.
For example, AMD's Milan (Zen 3) supports BRS rather than traditional
LBR. This requires specific configurations (attr.type = PERF_TYPE_RAW,
attr.config = RETIRED_TAKEN_BRANCH_INSTRUCTIONS) that differ from the
generic setup used within this test. Notably, it also probably doesn't
hold much value to special case perf event configurations for selected
micro architectures.

The --overwrite option implies --tail-synthesize, which collects non-sample
events reflecting the system status when recording finishes. However, when
evsel opening fails (e.g., unsupported event 'cycles-ct'), session->evlist
is not initialized and remains NULL. The code unconditionally calls
record__synthesize() in the error path, which iterates through the NULL
evlist pointer and causes a segfault.
To fix it, move the record__synthesize() call inside the error check block, so
it's only called when there was no error during recording, ensuring that evlist
is properly initialized.

[ Upstream commit 553d18c98a896094b99a01765b9698b204183d49 ]
On some machines, it caused troubles when it tried to find kernel
symbols. I think it's because kernel modules and kallsyms are messed
up during load and split.
Basically we want to make sure the kernel map is loaded and the code has
it in the lock_contention_read(). But recently we added more lookups in
the lock_contention_prepare() which is called before _read().
Also the kernel map (kallsyms) may not be the first one in the group
like on ARM. Let's use machine__kernel_map() rather than just loading
the first map.

BASH script at the very beginning.
But on some operating systems like Ubuntu, /bin/sh is actually pointed to

leads to syntax issues:

[ Upstream commit bed22c7b90af732978715a1789bca1c3cfa245a6 ]
ret_set_ksft_status() calls ksft_status_merge() with the current return
status and the last one. It treats a non-zero return code from
ksft_status_merge() as an indication that the return status was
overwritten by the last one and therefore overwrites the return message
with the last one.
Currently, ksft_status_merge() returns a non-zero return code even if
the current return status and the last one are equal. This results in
return messages being overwritten which is counter-productive since we
are more interested in the first failure message and not the last one.
Fix by changing ksft_status_merge() to only return a non-zero return
code if the current return status was actually changed.
Add a test case which checks that the first error message is not
overwritten.

commit 0e4ec14dc1ee4b1ec347729c225c3ca950f2bcf6 upstream.
In rare cases, when the test environment is very slow, some userspace
tests can fail because some expected events have not been seen.
Because the tests are expecting a long on-going connection, and they are
not waiting for the end of the transfer, it is fine to have a longer
timeout, and even go over the default one. This connection will be
killed at the end, after the verifications: increasing the timeout
doesn't change anything, apart from avoiding it to end before the end of
the verifications.
To play it safe, all userspace tests not waiting for the end of the
transfer are now having a longer timeout: 2 minutes.
The Fixes commit was making the connection longer, but still, the
default timeout would have stopped it after 1 minute, which might not be
enough in very slow environments.

The 'run_tests' function is executed in the background, but killing its
associated PID would not kill the children tasks running in the

To properly kill all background tasks, 'kill -- -PID' could be used, but

commit 290493078b96ce2ce3e60f55c23654acb678042a upstream.
In rare cases, when the test environment is very slow, some userspace
tests can fail because some expected events have not been seen.
Because the tests are expecting a long on-going connection, and they are
not waiting for the end of the transfer, it is fine to make the
connection longer. This connection will be killed at the end, after the
verifications, so making it longer doesn't change anything, apart from
avoid it to end before the end of the verifications
To play it safe, all userspace tests not waiting for the end of the
transfer are now sharing a longer file (128KB) at slow speed.

commit ee79980f7a428ec299f6261bea4c1084dcbc9631 upstream.
MPTCP Join "fastclose server" selftest is sometimes failing because the
client output file doesn't have the expected size, e.g. 296B instead of
1024B.
When looking at a packet trace when this happens, the server sent the
expected 1024B in two parts -- 100B, then 924B -- then the MP_FASTCLOSE.
It is then strange to see the client only receiving 296B, which would
mean it only got a part of the second packet. The problem is then not on
the networking side, but rather on the data reception side.
When mptcp_connect is launched with '-f -1', it means the connection
might stop before having sent everything, because a reset has been
received. When this happens, the program was directly stopped. But it is
also possible there are still some data to read, simply because the
previous 'read' step was done with a buffer smaller than the pending
data, see do_rnd_read(). In this case, it is important to read what's
left in the kernel buffers before stopping without error like before.
SIGPIPE is now ignored, not to quit the app before having read
everything.

commit aea73bae662a0e184393d6d7d0feb18d2577b9b9 upstream.
Some of these 'remove' tests rarely fail because a subflow has been
reset instead of cleanly removed. This can happen when one extra subflow
which has never carried data is being closed (FIN) on one side, while
the other is sending data for the first time.
To avoid such subflows to be used right at the end, the backup flag has
been added. With that, data will be only carried on the initial subflow.

commit 63c643aa7b7287fdbb0167063785f89ece3f000f upstream.
The "fallback due to TCP OoO" was never printed because the stat_ooo_now
variable was checked twice: once in the parent if-statement, and one in
the child one. The second condition was then always true then, and the
'else' branch was never taken.
The idea is that when there are more ACK + MP_CAPABLE than expected, the
test either fails if there was no out of order packets, or a notice is
printed.

commit dd4adb986a86727ed8f56c48b6d0695f1e211e65 upstream.
The tracing selftest "event-filter-function.tc" was failing because it
first runs the "sample_events" function that triggers the kmem_cache_free
event and it looks at what function was used during a call to "ls".
But the first time it calls this, it could trigger events that are used to
pull pages into the page cache.
The rest of the test uses the function it finds during that call to see if
it will be called in subsequent "sample_events" calls. But if there's no
need to pull pages into the page cache, it will not trigger that function
and the test will fail.
Call the "sample_events" twice to trigger all the page cache work before
it calls it to find a function to use in subsequent checks.

[ Upstream commit 57531b3416448d1ced36a2a974a4085ec43d57b0 ]
It seems that most of the tests prepare the interfaces once before the test
run (setup_prepare()), rely on setup_wait() to wait for link and only then
run the test(s).
local_termination brings the physical interfaces down and up during test
run but never wait for them to come up. If the auto-negotiation takes
some seconds, first test packets are being lost, which leads to
false-negative test results.
Use setup_wait() in run_test() to make sure auto-negotiation has been
completed after all simple_if_init() calls on physical interfaces and test
packets will not be lost because of the race against link establishment.

[ Upstream commit f8e8486702abb05b8c734093aab1606af0eac068 ]
The GRO self-test, gro.c, currently constructs IPv6 packets containing a
Hop-by-Hop Options header (IPPROTO_HOPOPTS) to ensure the GRO path
correctly handles IPv6 extension headers.
However, network elements may be configured to drop packets with the
Hop-by-Hop Options header (HBH). This causes the self-test to fail
in environments where such network elements are present.
To improve the robustness and reliability of this test in diverse
network environments, switch from using IPPROTO_HOPOPTS to
IPPROTO_DSTOPTS (Destination Options).
The Destination Options header is less likely to be dropped by
intermediate routers and still serves the core purpose of the test:
validating GRO's handling of an IPv6 extension header. This change
ensures the test can execute successfully without being incorrectly
failed by network policies outside the kernel's control.

Due to the gro_sender sending data packets and FIN packets
in very quick succession, these are received almost simultaneously
by the gro_receiver. FIN packets are sometimes processed before the
data packets leading to intermittent (~1/100) test failures.
This change adds a delay of 100ms before sending FIN packets
in gro:tcp test to avoid the out-of-order delivery. The same
mitigation already exists for the gro:ip test.

Quoted from musl wiki:
GNU getopt permutes argv to pull options to the front, ahead of
non-option arguments. musl and the POSIX standard getopt stop
processing options at the first non-option argument with no
permutation.
Thus these scripts stop working on musl since non-option arguments for
tools using getopt() (in this case, (ar)ping) do not always come last.
Fix it by reordering arguments.

[ Upstream commit e2cf2d5baa09248d3d50b73522594b778388e3bc ]
rss_ctx.test_rss_key_indir implicitly expects at least 5 queues,
as it checks that the traffic on first 2 queues is lower than
the remaining queues when we use all queues. Special case fewer
queues.

[ Upstream commit c158b5a570a188b990ef10ded172b8b93e737826 ]
Commit 0d6ccfe6b319 ("selftests: drv-net: rss_ctx: check for all-zero keys")
added a skip exception if NIC has fewer than 3 queues enabled,
but it's just constructing the object, it's not actually rising
this exception.
Before:
# Exception| net.lib.py.utils.CmdExitFailure: Command failed: ethtool -X enp1s0 equal 3 hkey d1:cc:77:47:9d:ea:15:f2:b9:6c:ef:68:62:c0:45:d5:b0:99:7d:cf:29:53:40:06:3d:8e:b9:bc:d4:70:89:b8:8d:59:04:ea:a9:c2:21:b3:55:b8:ab:6b:d9:48:b4:bd:4c:ff:a5:f0:a8:c2
not ok 1 rss_ctx.test_rss_key_indir
After:
ok 1 rss_ctx.test_rss_key_indir # SKIP Device has fewer than 3 queues (or doesn't support queue stats)

[ Upstream commit bc4c0a48bdad7f225740b8e750fdc1da6d85e1eb ]
The get_next_frame() function in psock_tpacket.c was missing a return
statement in its default switch case, leading to a compiler warning.
This was caused by a `bug_on(1)` call, which is defined as an
`assert()`, being compiled out because NDEBUG is defined during the
build.
Instead of adding a `return NULL;` which would silently hide the error
and could lead to crashes later, this change restores the original
author's intent. By adding `#undef NDEBUG` before including <assert.h>,
we ensure the assertion is active and will cause the test to abort if
this unreachable code is ever executed.
