2025-04-08selftests: mptcp: validate MPJoin HMacFailure countersMatthieu Baerts (NGI0)
The parent commit fixes an issue around these counters where one of them -- MPJoinAckHMacFailure -- was wrongly incremented in some cases. This makes sure the counter is always 0. It should be incremented only in case of corruption, or a wrong implementation, which should not be the case in these selftests.

2025-04-08selftests/mincore: Allow read-ahead pages to reach the end of the fileQiuxu Zhuo
When running the mincore_selftest on a system with an XFS file system, it failed the "check_file_mmap" test case due to the read-ahead pages reaching the end of the file. The failure log is as below: RUN global.check_file_mmap ... mincore_selftest.c:264:check_file_mmap:Expected i (1024) < vec_size (1024) mincore_selftest.c:265:check_file_mmap:Read-ahead pages reached the end of the file check_file_mmap: Test failed FAIL global.check_file_mmap This is because the read-ahead window size of the XFS file system on this machine is 4 MB, which is larger than the size from the #PF address to the end of the file. As a result, all the pages for this file are populated. blockdev --getra /dev/nvme0n1p5 8192 blockdev --getbsz /dev/nvme0n1p5 512 This issue can be fixed by extending the current FILE_SIZE 4MB to a larger number, but it will still fail if the read-ahead window size of the file system is larger enough. Additionally, in the real world, read-ahead pages reaching the end of the file can happen and is an expected behavior. Therefore, allowing read-ahead pages to reach the end of the file is a better choice for the "check_file_mmap" test case.

The use of the non POSIX-conformant symbol '==' would work in bash, but not in sh where the unexpected operator error would result in test_smoke.sh being skipped.

2025-04-06KVM: arm64: selftests: Explicitly set the page attrs to Inner-ShareableRaghavendra Rao Ananta
Atomic instructions such as 'ldset' in the guest have been observed to cause an EL1 data abort with FSC 0x35 (IMPLEMENTATION DEFINED fault (Unsupported Exclusive or Atomic access)) on Neoverse-N3. Per DDI0487L.a B2.2.6, atomic instructions are only architecturally guaranteed for Inner/Outer Shareable Normal Write-Back memory. For anything else the behavior is IMPLEMENTATION DEFINED and can lose atomicity, or, in this case, generate an abort. It would appear that selftests sets up the stage-1 mappings as Non Shareable, leading to the observed abort. Explicitly set the Shareability field to Inner Shareable for non-LPA2 page tables. Note that for the LPA2 page table format, translations for cacheable memory inherit the shareability attribute of the PTW, i.e. TCR_ELx.SH{0,1}.

2025-04-06KVM: arm64: selftests: Introduce and use hardware-definition macrosRaghavendra Rao Ananta
The kvm selftest library for arm64 currently configures the hardware fields, such as shift and mask in the page-table entries and registers, directly with numbers. While it add comments at places, it's better to rewrite them with appropriate macros to improve the readability and reduce the risk of errors. Hence, introduce macros to define the hardware fields and use them in the arm64 processor library. Most of the definitions are primary copied from the Linux's header, arch/arm64/include/asm/pgtable-hwdef.h. No functional change intended.

2025-04-04selftests/bpf: Make res_spin_lock test less verboseKumar Kartikeya Dwivedi
Currently, the res_spin_lock test is too chatty as it constantly prints the test_run results for each iteration in each thread, so in case verbose output is requested or things go wrong, it will flood the logs of CI and other systems with repeated messages that offer no valuable insight. Reduce this by doing assertions when the condition actually flips, and proceed to break out and exit the threads. We still assert to mark the test as failed and print the expected and reported values.

2025-04-04KVM: selftests: Add option to rseq test to override /dev/cpu_dma_latencySean Christopherson
Add a "-l <latency>" param to the rseq test so that the user can override /dev/cpu_dma_latency, as described by the test's suggested workaround for not being able to complete enough migrations. cpu_dma_latency is not a normal file, even as far as procfs files go. Writes to cpu_dma_latency only persist so long as the file is open, e.g. so that the kernel automatically reverts back to a power-optimized state once the sensitive workload completes. Provide the necessary functionality instead of effectively forcing the user to write a non-obvious wrapper.

Looking at the kernel code, I see that kernel does add link-local address automatically in init_loopback(), but that is called from ipv6 notifier block. So, in turn the userspace that brought up the loopback interface may see rtnetlink ACK earlier than addrconf_notify() does it's job (at least, on a slow VM such as netdev). Probably, for ipv4 it's the same, judging by inetdev_event(). The fix is quite simple: set the link-local route straight after bringing the loopback interface. That will make it synchronous.
