From 4d695869d3fb952d6f690bec0260ffe2a8b99b37 Mon Sep 17 00:00:00 2001 From: Benjamin Tissoires Date: Wed, 17 Jan 2024 14:27:15 +0100 Subject: selftests/hid: wacom: fix confidence tests The device is exported with a fuzz of 4, meaning that the `+ t` here is removed by the fuzz algorithm, making those tests failing.

R. A. Prado Date: Mon, 22 Jan 2024 11:29:18 -0300 Subject: kselftest: dt: Stop relying on dirname to improve performance When walking directory trees, instead of looking for specific files and running dirname to get the parent folder, traverse all folders and ignore the ones not containing the desired files. This avoids the need to call dirname inside the loop, which drastically decreases run time: Running locally on a mt8192-asurada-spherion, which reports 160 test cases, has gone from 5.5s to 2.9s, while running remotely with an nfsroot has gone from 13.5s to 5.5s. This change has a side-effect, which is that the root DT node now also shows in the output, even though it isn't expected to bind to a driver. However there shouldn't be a matching driver for the board compatible, so the end result will be just an extra skipped test: ok 1 / # SKIP Reported-by: Mark Brown Closes: https://lore.kernel.org/all/310391e8-fdf2-4c2f-a680-7744eb685177@sirena.org.uk Fixes: 14571ab1ad21 ("kselftest: Add new test for detecting unprobed Devicetree devices") Tested-by: Mark Brown Signed-off-by: Nícolas F.

As the comment states, munmap will failure if its not HUGEPAGE aligned. This is due to the length of the mapping being 1/2 the size of the hugepage causing the munmap to not be hugepage aligned. Fix this by making the mapping length the full hugepage if the hugepage is larger than the length of the mapping.

Check for the flag to be set to avoid false test failures on systems that do not have this cpu flag set. The test does a series of mmap calls including three using the MAP_FIXED flag and specifying an address that is 1<<47 or 1<<48. These addresses are only available if you are using level 5 page tables, which requires both the CPU to have the capabiltiy (la57 flag) and the kernel to be configured. Currently the test only checks for the kernel configuration option, so this test can still report a false positive. Here are the three failing lines: $ ./va_high_addr_switch | grep FAILED mmap(ADDR_SWITCH_HINT, 2 * PAGE_SIZE, MAP_FIXED): 0xffffffffffffffff - FAILED mmap(HIGH_ADDR, MAP_FIXED): 0xffffffffffffffff - FAILED mmap(ADDR_SWITCH_HINT, 2 * PAGE_SIZE, MAP_FIXED): 0xffffffffffffffff - FAILED I thought (for about a second) refactoring the test so that these three mmap calls will only be run on systems with the level 5 page tables available, but the whole point of the test is to check the level 5 feature...

Fix this behaviour. Up until commit efa7df3e3bb5 ("mm: align larger anonymous mappings on THP boundaries"), this buggy behavior was (usually) masked because the alignment difference was always less than PMD-size. But since the mentioned commit, `ksm_tests -H -s 100` started failing.

This is because when re-opening the file and parsing the header, Perf expects that any file that has more than one event has the sample ID flag set. Perf record already sets the flag in a similar way when there is more than one event, so add the same logic to evlist__new_default(). evlist__new_default() is only currently used in tests, so I don't expect this change to have any other side effects. The other tests that use it don't save and re-open the file so don't hit this issue. The session topology test has been failing on Arm big.LITTLE platforms since commit 251aa040244a3b17 ("perf parse-events: Wildcard most "numeric" events") when evlist__new_default() started opening multiple events for 'cycles'.

After each test, new dmesg entries are determined by the 'comm' utility comparing a saved, pre-test copy of dmesg to post-test dmesg output. Alexander reports that the 'comm --nocheck-order -13' invocation used by the tests can be confused when dmesg entry timestamps vary in magnitude (ie, "[ 98.820331]" vs. "[ 100.031067]"), in which case, additional messages are reported as new. The unexpected entries then spoil the test results. Instead of relying on 'comm' or 'diff' to determine new testing dmesg entries, refactor the code: - pre-test : log a unique canary dmesg entry - test : run tests, log messages - post-test : filter dmesg starting from pre-test message Reported-by: Alexander Gordeev Closes: https://lore.kernel.org/live-patching/ZYAimyPYhxVA9wKg@li-008a6a4c-3549-11b2-a85c-c5cc2836eea2.ibm.com/ Signed-off-by: Joe Lawrence Acked-by: Alexander Gordeev Tested-by: Marcos Paulo de Souza Reviewed-by: Marcos Paulo de Souza Acked-by: Miroslav Benes Signed-off-by: Shuah Khan --- tools/testing/selftests/livepatch/functions.sh | 37 ++++++++++++-------------- 1 file changed, 17 insertions(+), 20 deletions(-) (limited to 'tools') diff --git a/tools/testing/selftests/livepatch/functions.sh b/tools/testing/selftests/livepatch/functions.sh index c8416c54b463..b1fd7362c2fe 100644 --- a/tools/testing/selftests/livepatch/functions.sh +++ b/tools/testing/selftests/livepatch/functions.sh @@ -42,17 +42,6 @@ function die() { exit 1 } -# save existing dmesg so we can detect new content -function save_dmesg() { - SAVED_DMESG=$(mktemp --tmpdir -t klp-dmesg-XXXXXX) - dmesg > "$SAVED_DMESG" -} - -# cleanup temporary dmesg file from save_dmesg() -function cleanup_dmesg_file() { - rm -f "$SAVED_DMESG" -} - function push_config() { DYNAMIC_DEBUG=$(grep '^kernel/livepatch' /sys/kernel/debug/dynamic_debug/control | \ awk -F'[: ]' '{print "file " $1 " line " $2 " " $4}') @@ -99,7 +88,6 @@ function set_ftrace_enabled() { function cleanup() { pop_config - cleanup_dmesg_file } # setup_config - save the current config and set a script exit trap that @@ -280,7 +268,15 @@ function set_pre_patch_ret { function start_test { local test="$1" - save_dmesg + # Dump something unique into the dmesg log, then stash the entry + # in LAST_DMESG.

Let's additionally log each result in KTAP format so that automated systems parsing the test output will see each comparison as a test case. The original logs are left in place since they provide the actual numbers for analysis. As part of this rework the flow for the main program so that when we skip tests we still log all the tests we skip, this is because the standard KTAP headers and footers include counts of the number of expected and run tests.

To align with this, invert the boolean values used when calling verify_counters() within the end_server() function. As a result of this typo, the test didn't correctly check for the non-symmetrical scenario, where i.e. peer-A uses a key <100:200> to send data, but peer-B uses another key <105:205> to send its data.

However, if the addresses were never added to begin with due to some error in device setup, the test function currently passes. This is a false positive since in that situation the test did not actually exercise the intended functionality. Add a check that the expected addresses are indeed present after device setup.

Without this change, running network tests as a non-root user but with all capabilities would fail at the setup_loopback() step with "RTNETLINK answers: Operation not permitted". The issue is only visible when running tests with non-root users (i.e. only relying on ambient capabilities). Indeed, when configuring the network interface, the "ip" command is called, which may lead to the special handling of capabilities for the root user by execve(2). If root is the caller, then the inherited, permitted and effective capabilities are all reset, which then includes CAP_NET_ADMIN. However, if a non-root user is the caller, then ambient capabilities are masked by the inherited ones, which were explicitly dropped. To make execution deterministic whatever users are running the tests, set the noroot secure bit for each test, and set the inheritable and ambient capabilities to CAP_NET_ADMIN, the only capability that may be required after an execve(2). Factor out _effective_cap() into _change_cap(), and use it to manage ambient capabilities with the new set_ambient_cap() and clear_ambient_cap() helpers.

The counters are checked on the server's side, as the server listener has TCP-AO/TCP-MD5/no keys for different peers. All tests run in the same namespaces with the same veth pair, created in test_init(). After close() in both client and server, the sides go through the regular FIN/ACK + FIN/ACK sequence, which goes in the background. If the selftest has already started a new testing scenario, read per-netns counters - it may fail in the end iff it doesn't expect the TCPAOGood per-netns counters go up during the test.

This fixes a bug where the extra post to sem_vcpu_cont may not be consumed, which results in failures in subsequent runs of the testcases. The bug likely was missed during development as x86 supports only a single "guest mode", i.e. there aren't any subsequent testcases after the dirty ring test, because for_each_guest_mode() only runs a single iteration. For the regular dirty log testcases, letting the vCPU run one extra iteration is a non-issue as the vCPU worker waits on sem_vcpu_cont if and only if the worker is explicitly told to stop (vcpu_sync_stop_requested). But for the dirty ring test, which needs to periodically stop the vCPU to reap the dirty ring, letting the vCPU resume the guest _after_ the last iteration means the vCPU will get stuck without an extra "continue". However, blindly firing off an post to sem_vcpu_cont isn't guaranteed to be consumed, e.g. if the vCPU worker sees host_quit==true before resuming the guest. This results in a dangling sem_vcpu_cont, which leads to subsequent iterations getting out of sync, as the vCPU worker will continue on before the main task is ready for it to resume the guest, leading to a variety of asserts, e.g. ==== Test Assertion Failure ==== dirty_log_test.c:384: dirty_ring_vcpu_ring_full pid=14854 tid=14854 errno=22 - Invalid argument 1 0x00000000004033eb: dirty_ring_collect_dirty_pages at dirty_log_test.c:384 2 0x0000000000402d27: log_mode_collect_dirty_pages at dirty_log_test.c:505 3 (inlined by) run_test at dirty_log_test.c:802 4 0x0000000000403dc7: for_each_guest_mode at guest_modes.c:100 5 0x0000000000401dff: main at dirty_log_test.c:941 (discriminator 3) 6 0x0000ffff9be173c7: ?? ??:0 7 0x0000ffff9be1749f: ?? ??:0 8 0x000000000040206f: _start at ??:?

I am unable to reproduce the failure locally, but I can see how it can happen given that learning is first enabled and only then the ingress tc filter is configured. On debug kernels the time window between these two operations is longer compared to regular kernels, allowing random packets to be transmitted and trigger learning. Fix by reversing the order and configure the ingress tc filter before enabling learning.

Then, much later, we ended up removing the workaround in commit 43c249ea0b1e ("compiler-gcc.h: remove ancient workaround for gcc PR 58670") because we no longer supported building the kernel with the affected gcc versions, but we left the macro uses around. Now, Sean Christopherson reports a new version of a very similar problem, which is fixed by re-applying that ancient workaround. But the problem in question is limited to only the 'asm goto with outputs' cases, so instead of re-introducing the old workaround as-is, let's rename and limit the workaround to just that much less common case. It looks like there are at least two separate issues that all hit in this area: (a) some versions of gcc don't mark the asm goto as 'volatile' when it has outputs: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98619 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110420 which is easy to work around by just adding the 'volatile' by hand. (b) Internal compiler errors: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110422 which are worked around by adding the extra empty 'asm' as a barrier, as in the original workaround. but the problem Sean sees may be a third thing since it involves bad code generation (not an ICE) even with the manually added 'volatile'. but the same old workaround works for this case, even if this feels a bit like voodoo programming and may only be hiding the issue.

This points to the second poll() in the test which is expected to wait for the sender to send the rest of the data. Apparently under some conditions that doesn't happen within 5ms, bump the timeout to 20ms.
