2024-02-10work around gcc bugs with 'asm goto' with outputsLinus Torvalds2-3/+3
We've had issues with gcc and 'asm goto' before, and we created a 'asm_volatile_goto()' macro for that in the past: see commits 3f0116c3238a ("compiler/gcc4: Add quirk for 'asm goto' miscompilation bug") and a9f180345f53 ("compiler/gcc4: Make quirk for asm_volatile_goto() unconditional"). 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.

Packet path and netlink dump/get path still use current time to check for expiration. 9) Restore NF_REPEAT in nfnetlink_queue, from Florian Westphal. 10) map_index needs to be percpu and per-set, not just percpu. At this time its possible for a pipapo set to fill the all-zero part with ones and take the 'might have bits set' as 'start-from-zero' area. From Florian Westphal. This includes three patches: - Change scratchpad area to a structure that provides space for a per-set-and-cpu toggle and uses it of the percpu one. - Add a new free helper to prepare for the next patch. - Remove the scratch_aligned pointer and makes AVX2 implementation use the exact same memory addresses for read/store of the matching state. netfilter pull request 24-02-08 * tag 'nf-24-02-08' of git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf: netfilter: nft_set_pipapo: remove scratch_aligned pointer netfilter: nft_set_pipapo: add helper to release pcpu scratch area netfilter: nft_set_pipapo: store index in scratch maps netfilter: nft_set_rbtree: skip end interval element from gc netfilter: nfnetlink_queue: un-break NF_REPEAT netfilter: nf_tables: use timestamp to check for set element timeout netfilter: nft_ct: reject direction for ct id netfilter: ctnetlink: fix filtering for zone 0 netfilter: ipset: Missing gc cancellations fixed netfilter: nft_set_pipapo: remove static in nft_pipapo_get() netfilter: nft_compat: restrict match/target protocol to u16 netfilter: nft_compat: reject unused compat flag netfilter: nft_compat: narrow down revision to unsigned 8-bits ==================== Link: https://lore.kernel.org/r/20240208112834.1433-1-pablo@netfilter.org Signed-off-by: Paolo Abeni <pabeni@redhat.com>

2024-02-07selftests: cmsg_ipv6: repeat the exact packetJakub Kicinski1-2/+2
cmsg_ipv6 test requests tcpdump to capture 4 packets, and sends until tcpdump quits. Only the first packet is "real", however, and the rest are basic UDP packets. So if tcpdump doesn't start in time it will miss the real packet and only capture the UDP ones. This makes the test fail on slow machine (no KVM or with debug enabled) 100% of the time, while it passes in fast environments. Repeat the "real" / expected packet.

2024-02-06selftests/net: Amend per-netns counter checksDmitry Safonov1-6/+6
Selftests here check not only that connect()/accept() for TCP-AO/TCP-MD5/non-signed-TCP combinations do/don't establish connections, but also counters: those are per-AO-key, per-socket and per-netns. 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. Let's just kill both TCP-AO sides - that will avoid any asynchronous background TCP-AO segments going to either sides.

2024-02-05selftests: net: let big_tcp test cope with slow envPaolo Abeni1-1/+3
In very slow environments, most big TCP cases including segmentation and reassembly of big TCP packets have a good chance to fail: by default the TCP client uses write size well below 64K. If the host is low enough autocorking is unable to build real big TCP packets. Address the issue using much larger write operations. Note that is hard to observe the issue without an extremely slow and/or overloaded environment; reduce the TCP transfer time to allow for much easier/faster reproducibility.

That introduces unneeded latency and on very slow and busy host it can fail. Additionally the test starts again the same listener in the same namespace on the same port, just after the previous connection completed. Fast host can attempt starting the new server before the old one really closed the socket.

2024-02-01selftests: mptcp: join: stop transfer when check is done (part 2)Matthieu Baerts (NGI0)1-14/+9
Since the "Fixes" commits mentioned below, the newly added "userspace pm" subtests of mptcp_join selftests are launching the whole transfer in the background, do the required checks, then wait for the end of transfer.

Since the "Fixes" commit mentioned below, "userspace pm" subtests of mptcp_join selftests introduced in v6.5 are launching the whole transfer in the background, do the required checks, then wait for the end of transfer. There is no need to wait longer, especially because the checks at the end of the transfer are ignored (which is fine). This saves quite a few seconds in slow environments.

With the same title printed in TAP, the tests are considered as the same ones. Now, it is possible to override this prefix by using MPTCP_LIB_KSFT_TEST env var, and have a different title.

2024-02-01selftests: mptcp: increase timeout to 30 minMatthieu Baerts (NGI0)1-1/+1
On very slow environments -- e.g. when QEmu is used without KVM --, mptcp_join.sh selftest can take a bit more than 20 minutes. Bump the default timeout by 50% as it seems normal to take that long on some environments. When a debug kernel config is used, this selftest will take even longer, but that's certainly not a common test env to consider for the timeout. The Fixes tag that has been picked here is there simply to help having this patch backported to older stable versions. It is difficult to point to the exact commit that made some env reaching the timeout from time to time.

2024-02-01selftests: bonding: Check initial stateBenjamin Poirier1-0/+11
The purpose of the test_LAG_cleanup() function is to check that some hardware addresses are removed from underlying devices after they have been unenslaved. The test function simply checks that those addresses are not present at the end. 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. This makes the test function more robust. I noticed this problem when running the team/dev_addr_lists.sh test on a system without support for dummy and ipv6: tools/testing/selftests/drivers/net/team# ./dev_addr_lists.sh Error: Unknown device type.

To align with this, invert the boolean values used when calling verify_counters() within the end_server() function.

The seccomp benchmark test makes a number of checks on the performance it measures and logs them to the output but does so in a custom format which none of the automated test runners understand meaning that the chances that anyone is paying attention are slim. 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.

2024-01-30selftests/livepatch: fix and refactor new dmesg message codeJoe Lawrence1-20/+17
The livepatching kselftests rely on comparing expected vs. observed dmesg output. 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 <agordeev@linux.ibm.com> Closes: https://lore.kernel.org/live-patching/ZYAimyPYhxVA9wKg@li-008a6a4c-3549-11b2-a85c-c5cc2836eea2.ibm.com/ Signed-off-by: Joe Lawrence <joe.lawrence@redhat.com> Acked-by: Alexander Gordeev <agordeev@linux.ibm.com> Tested-by: Marcos Paulo de Souza <mpdesouza@suse.com> Reviewed-by: Marcos Paulo de Souza <mpdesouza@suse.com> Acked-by: Miroslav Benes <mbenes@suse.cz> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>

2024-01-30perf evlist: Fix evlist__new_default() for > 1 core PMUJames Clark1-1/+8
The 'Session topology' test currently fails with this message when evlist__new_default() opens more than one event: 32: Session topology : --- start --- templ file: /tmp/perf-test-vv5YzZ Using CPUID 0x00000000410fd070 Opening: unknown-hardware:HG ------------------------------------------------------------ perf_event_attr: type 0 (PERF_TYPE_HARDWARE) config 0xb00000000 disabled 1 ------------------------------------------------------------ sys_perf_event_open: pid 0 cpu -1 group_fd -1 flags 0x8 = 4 Opening: unknown-hardware:HG ------------------------------------------------------------ perf_event_attr: type 0 (PERF_TYPE_HARDWARE) config 0xa00000000 disabled 1 ------------------------------------------------------------ sys_perf_event_open: pid 0 cpu -1 group_fd -1 flags 0x8 = 5 non matching sample_type FAILED tests/topology.c:73 can't get session ---- end ---- Session topology: FAILED! 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'.
