2024-04-12selftests: netfilter: move to net subdirFlorian Westphal
.. so this can start re-using existing lib.sh infra in next patches. Several of these scripts will not work, e.g. because they assume rp_filter is disabled, or reliance on a particular version/flavor of "netcat" tool. Add config settings for them. nft_trans_stress.sh script is removed, it also exists in the nftables userspace selftests. I do not see a reason to keep two versions in different repositories/projects. The settings file is removed for now: It was used to increase the timeout to avoid slow scripts from getting zapped by the 45s timeout, but some of the slow scripts can be sped up. Re-add it later for scripts that cannot be sped up easily. Update MAINTAINERS to reflect that future updates to netfilter scripts should go through netfilter-devel@.

2024-04-12selftests: kselftest: Mark functions that unconditionally call exit() as ↵Nathan Chancellor
__noreturn After commit 6d029c25b71f ("selftests/timers/posix_timers: Reimplement check_timer_distribution()"), clang warns: tools/testing/selftests/timers/../kselftest.h:398:6: warning: variable 'major' is used uninitialized whenever '||' condition is true [-Wsometimes-uninitialized] 398 | if (uname(&info) || sscanf(info.release, "%u.%u.", &major, &minor) != 2) | ^~~~~~~~~~~~ tools/testing/selftests/timers/../kselftest.h:401:9: note: uninitialized use occurs here 401 | return major > min_major || (major == min_major && minor >= min_minor); | ^~~~~ tools/testing/selftests/timers/../kselftest.h:398:6: note: remove the '||' if its condition is always false 398 | if (uname(&info) || sscanf(info.release, "%u.%u.", &major, &minor) != 2) | ^~~~~~~~~~~~~~~ tools/testing/selftests/timers/../kselftest.h:395:20: note: initialize the variable 'major' to silence this warning 395 | unsigned int major, minor; | ^ | = 0 This is a false positive because if uname() fails, ksft_exit_fail_msg() will be called, which unconditionally calls exit(), a noreturn function. However, clang does not know that ksft_exit_fail_msg() will call exit() at the point in the pipeline that the warning is emitted because inlining has not occurred, so it assumes control flow will resume normally after ksft_exit_fail_msg() is called. Make it clear to clang that all of the functions that call exit() unconditionally in kselftest.h are noreturn transitively by marking them explicitly with '__attribute__((__noreturn__))', which clears up the warning above and any future warnings that may appear for the same reason.

The symbol__annotate2() initializes some data structures needed by TUI. It has a logic to prevent calling it multiple times by checking if it has the annotated source. But data type profiling uses a different code (symbol__annotate) to allocate the annotated lines in advance. So TUI missed to call symbol__annotate2() when it shows the annotation browser. Make symbol__annotate() reentrant and handle that situation properly.

2024-04-10selftests: fib_rule_tests: Add VRF testsIdo Schimmel
After commit 40867d74c374 ("net: Add l3mdev index to flow struct and avoid oif reset for port devices") it is possible to configure FIB rules that match on iif / oif being a l3mdev port. It was not possible before as these parameters were reset to the ifindex of the l3mdev device itself prior to the FIB rules lookup. Add tests that cover this functionality as it does not seem to be covered by existing ones and I am aware of at least one user that needs this functionality in addition to the one mentioned in [1]. Reuse the existing FIB rules tests by simply configuring a VRF prior to the test and removing it afterwards. Differentiate the output of the non-VRF tests from the VRF tests by appending "(VRF)" to the test name if a l3mdev FIB rule is present. Verified that these tests do fail on kernel 5.15.y which does not include the previously mentioned commit: # ./fib_rule_tests.sh -t fib_rule6_vrf [...] TEST: rule6 check: oif redirect to table (VRF) [FAIL] [...] TEST: rule6 check: iif redirect to table (VRF) [FAIL] # ./fib_rule_tests.sh -t fib_rule4_vrf [...] TEST: rule4 check: oif redirect to table (VRF) [FAIL] [...] TEST: rule4 check: iif redirect to table (VRF) [FAIL] [1] https://lore.kernel.org/netdev/20200922131122.GB1601@ICIPI.localdomain/ Signed-off-by: Ido Schimmel <idosch@nvidia.com> Reviewed-by: David Ahern <dsahern@kernel.org> Link: https://lore.kernel.org/r/20240409110816.2508498-1-idosch@nvidia.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2024-04-10hv/hv_kvp_daemon: Handle IPv4 and Ipv6 combination for keyfile formatShradha Gupta
If the network configuration strings are passed as a combination of IPv4 and IPv6 addresses, the current KVP daemon does not handle processing for the keyfile configuration format. With these changes, the keyfile config generation logic scans through the list twice to generate IPv4 and IPv6 sections for the configuration files to handle this support.

The struct adjtimex freq field takes a signed value who's units are in shifted (<<16) parts-per-million. Unfortunately for negative adjustments, the straightforward use of: freq = ppm << 16 trips undefined behavior warnings with clang: valid-adjtimex.c:66:6: warning: shifting a negative signed value is undefined [-Wshift-negative-value] -499<<16, ~~~~^ valid-adjtimex.c:67:6: warning: shifting a negative signed value is undefined [-Wshift-negative-value] -450<<16, ~~~~^ .. Fix it by using a multiply by (1 << 16) instead of shifting negative values in the valid-adjtimex test case. Align the values for better readability.

2024-04-09selftests/timers/posix_timers: Reimplement check_timer_distribution()Oleg Nesterov
check_timer_distribution() runs ten threads in a busy loop and tries to test that the kernel distributes a process posix CPU timer signal to every thread over time. There is not guarantee that this is true even after commit bcb7ee79029d ("posix-timers: Prefer delivery of signals to the current thread") because that commit only avoids waking up the sleeping process leader thread, but that has nothing to do with the actual signal delivery. As the signal is process wide the first thread which observes sigpending and wins the race to lock sighand will deliver the signal. Testing shows that this hangs on a regular base because some threads never win the race. The comment "This primarily tests that the kernel does not favour any one." is wrong. The kernel does favour a thread which hits the timer interrupt when CLOCK_PROCESS_CPUTIME_ID expires. Rewrite the test so it only checks that the group leader sleeping in join() never receives SIGALRM and the thread which burns CPU cycles receives all signals. In older kernels which do not have commit bcb7ee79029d ("posix-timers: Prefer delivery of signals to the current thread") the test-case fails immediately, the very 1st tick wakes the leader up. Otherwise it quickly succeeds after 100 ticks. CI testing wants to use newer selftest versions on stable kernels. In this case the test is guaranteed to fail. So check in the failure case whether the kernel version is less than v6.3 and skip the test result in that case.

max_guest_memory_test uses ucalls to sync with the host, but it also resets the guest RIP back to its initial value in between tests stages. This makes the guest never reach the code which frees the ucall struct and since a fixed pool of 512 ucall structs is used, the test starts to fail when more that 256 vCPUs are used. Fix that by replacing the manual register reset with a loop in the guest code.
