| * | selftests: mptcp: Initialize variables to quiet gcc 12 warningsMat Martineau2022-06-283-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In a few MPTCP selftest tools, gcc 12 complains that the 'sock' variable might be used uninitialized. This is a false positive because the only code path that could lead to uninitialized access is where getaddrinfo() fails, but the local xgetaddrinfo() wrapper exits if such a failure occurs. Initialize the 'sock' variable anyway to allow the tools to build with gcc 12.

| * | selftests: mptcp: more stable diag testsPaolo Abeni2022-06-281-8/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mentioned test-case still use an hard-coded-len sleep to wait for a relative large number of connection to be established. On very slow VM and with debug build such timeout could be exceeded, causing failures in our CI. Address the issue polling for the expected condition several times, up to an unreasonable high amount of time. On reasonably fast system the self-tests will be faster then before, on very slow one we will still catch the correct condition.

* | | perf inject: Adjust output data offset for backward compatibilityRaul Silvera2022-06-263-1/+17

If there has been a change on the size of the header, as happened in v5.12 -> v5.13, the new offsets will be wrong, resulting in a corrupted output file. This change adds the function perf_session__data_offset to compute the data offset based on the current header size, and uses that instead of the offset from the original input file.

Commit b4a028c4d031 ("ipv4: ping: fix bind address validity check") fixes a regression which incorrectly removed some checks for bind address validation. In addition, it introduces regression tests for those specific checks. However, those regression tests are defective, in that they perform the tests using an incorrect combination of bind flags. As a result, those tests fail when they should succeed. This commit introduces additional regression tests for nonlocal binding and fixes the defective regression tests. It also introduces new set_sysctl calls for the ipv4_bind test group, as to perform the ICMP binding tests it is necessary to allow ICMP socket creation by setting the net.ipv4.ping_group_range knob.

However, this caused an unintended regression in ping_check_bind_addr(), which previously would reject binding to multicast and broadcast addresses, but now these are both incorrectly allowed as reported in [1]. This patch restores the original check. A simple reordering is done to improve readability and make it evident that multicast and broadcast addresses should not be allowed. Also, add an early exit for INADDR_ANY which replaces lost behavior added by commit 0ce779a9f501 ("net: Avoid unnecessary inet_addr_type() call when addr is INADDR_ANY"). Furthermore, this patch introduces regression selftests to catch these specific cases.

Instead we must pass --target to the compiler to tell it what to output, kselftest was not doing this so cross compilation of kselftest using clang resulted in kselftest being built for the host architecture.

This patch strictly checks the record operation type, it only sets data source only for the operation types ARM_SPE_LD and ARM_SPE_ST, otherwise, returns zero for data source. Therefore, we can synthesize memory samples only when data source is a non-zero value, the function arm_spe__is_memory_event() is useless and removed.

Therefore this tests fails on s390. Similar issues exist for per-die and per-socket output which is not supported on s390.

However that annotation is now deprecated because it doesn't work with IBT, where objtool runs on vmlinux.o instead of individual translation units. Instead, use more fine-grained function-specific annotations: - The 'save_mcount_regs' macro does funny things with the frame pointer. Use STACK_FRAME_NON_STANDARD_FP to tell objtool to ignore the functions using it. - The return_to_handler() "function" isn't actually a callable function. Instead of being called, it's returned to. The real return address isn't on the stack, so unwinding is already doomed no matter which unwinder is used. So just remove the STT_FUNC annotation, telling objtool to ignore it. That also removes the implicit ANNOTATE_NOENDBR, which now needs to be made explicit.
