Add test cases for externally validated neighbor entries, testing both IPv4 and IPv6. Name the file "test_neigh.sh" so that it could be possibly extended in the future with more neighbor test cases. Example output: # ./test_neigh.sh TEST: IPv4 "extern_valid" flag: Add entry [ OK ] TEST: IPv4 "extern_valid" flag: Add with an invalid state [ OK ] TEST: IPv4 "extern_valid" flag: Add with "use" flag [ OK ] TEST: IPv4 "extern_valid" flag: Replace entry [ OK ] TEST: IPv4 "extern_valid" flag: Replace entry with "managed" flag [ OK ] TEST: IPv4 "extern_valid" flag: Replace with an invalid state [ OK ] TEST: IPv4 "extern_valid" flag: Interface down [ OK ] TEST: IPv4 "extern_valid" flag: Carrier down [ OK ] TEST: IPv4 "extern_valid" flag: Transition to "reachable" state [ OK ] TEST: IPv4 "extern_valid" flag: Transition back to "stale" state [ OK ] TEST: IPv4 "extern_valid" flag: Forced garbage collection [ OK ] TEST: IPv4 "extern_valid" flag: Periodic garbage collection [ OK ] TEST: IPv6 "extern_valid" flag: Add entry [ OK ] TEST: IPv6 "extern_valid" flag: Add with an invalid state [ OK ] TEST: IPv6 "extern_valid" flag: Add with "use" flag [ OK ] TEST: IPv6 "extern_valid" flag: Replace entry [ OK ] TEST: IPv6 "extern_valid" flag: Replace entry with "managed" flag [ OK ] TEST: IPv6 "extern_valid" flag: Replace with an invalid state [ OK ] TEST: IPv6 "extern_valid" flag: Interface down [ OK ] TEST: IPv6 "extern_valid" flag: Carrier down [ OK ] TEST: IPv6 "extern_valid" flag: Transition to "reachable" state [ OK ] TEST: IPv6 "extern_valid" flag: Transition back to "stale" state [ OK ] TEST: IPv6 "extern_valid" flag: Forced garbage collection [ OK ] TEST: IPv6 "extern_valid" flag: Periodic garbage collection [ OK ] Signed-off-by: Ido Schimmel <idosch@nvidia.com> Link: https://patch.msgid.link/20250626073111.244534-3-idosch@nvidia.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2025-06-30cxl_test: Limit location for fake CFMWS to mappable rangeJonathan Cameron
Some architectures (e.g. arm64) only support memory hotplug operations on a restricted set of physical addresses. This applies even when we are faking some CXL fixed memory windows for the purposes of cxl_test. That range can be queried with mhp_get_pluggable_range(true). Use the minimum of that the top of that range and iomem_resource.end to establish the 64GiB region used by cxl_test. From thread #2 which was related to the issue in #1.

2025-06-30perf build: Specify shellcheck should use bashCollin Funk
When someone has a global shellcheckrc file, for example at ~/.config/shellcheckrc, with the directive 'shell=sh', building perf will fail with many shellcheck errors like: In tests/shell/base_probe/test_adding_kernel.sh line 294: (( TEST_RESULT += $? )) ^---------------------^ SC3006 (warning): In POSIX sh, standalone ((..)) is undefined. For more information: https://www.shellcheck.net/wiki/SC3006 -- In POSIX sh, standalone ((..)) is... make[5]: *** [tests/Build:91: tests/shell/base_probe/test_adding_kernel.sh.shellcheck_log] Error 1 Passing the '-s bash' option ensures that it runs correctly regardless of a developers global configuration. This patch adds '-s bash' and other options to the SHELLCHECK variable in Makefile.perf and makes use of the variable consistently.

2025-06-30perf test annotate: Use --percent-limit rather than head to reduce outputIan Rogers
The annotate test was sped up by Thomas Richter <tmricht@linux.ibm.com> in commit 658a8805cb60 ("perf test: Speed up test case 70 annotate basic tests") by reducing the annotate output using head. This causes flakes on hybrid machines where the first event dumped may not have the samples for the test within it. Rather than reduce the output using `head` switch to `--percent-limit 10` which will stop annotate dumping functions that have an overhead of less than 10%, the noploop program should be using more. Add the missing objdump option for the pipe mode version of the objdump with a command test.

2025-06-30perf test: perf header test fails on s390Thomas Richter
commit 2d584688643fa ("perf test: Add header shell test") introduced a new test case for perf header. It fails on s390 because call graph option -g is not supported on s390. Also the option --call-graph dwarf is only supported for the event cpu-clock. Remove this option and the test succeeds.

2025-06-28tools/nolibc: MIPS: add support for N64 and N32 ABIsThomas Weißschuh
Add support for the MIPS 64bit N64 and ILP32 N32 ABIs. In addition to different byte orders and ABIs there are also different releases of the MIPS architecture. To avoid blowing up the test matrix, only add a subset of all possible test combinations.

2025-06-28tools/nolibc: MIPS: drop noreorder optionThomas Weißschuh
There are no more statements in the assembly code which would require the usage of ".set noreorder". Remove the option. This also allows removal of the manual "nop" instruction in the delay slot.

2025-06-28tools/nolibc: MIPS: drop manual stack pointer alignmentThomas Weißschuh
The stack pointer is already aligned by the kernel to a multiple of 16. All modifications of the register have been removed from the entrypoint, so the manual realignment is unnecessary. Drop the manual alignment. Suggested-by: Maciej W.

2025-06-28tools/nolibc: MIPS: drop $gp setupThomas Weißschuh
The setup of the global pointer "$gp" register was necessary when the C entrypoint was called through "jal <symbol>". However since commit 0daf8c86a451 ("tools/nolibc: mips: load current function to $t9") "jalr" is used instead which does not require "$gp". Remove the unnecessary $gp setup, simplifying the code and opening the road for some other cleanups. Suggested-by: Maciej W.
