Protect against common programming errors through compiler warnings. These warnings are also used for the kernel itself.

2025-07-01selftests: vDSO: chacha: Correctly skip test if necessaryThomas Weißschuh1-1/+2
According to kselftest.h ksft_exit_skip() is not meant to be called when a plan has already been printed. Use the recommended function ksft_test_result_skip(). This fixes a bug, where the TAP output would be invalid when skipping: TAP version 13 1..1 ok 2 # SKIP Not implemented on architecture The SKIP line should start with "ok 1" as the plan only contains one test.

2025-07-01cxl_test: Limit location for fake CFMWS to mappable rangeJonathan Cameron2-1/+7
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.

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.

2025-06-30perf test annotate: Use --percent-limit rather than head to reduce outputIan Rogers1-7/+8
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.

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".

cgroup_xattr/read_cgroupfs_xattr has two issues: 1. cgroup_xattr/read_cgroupfs_xattr messes up lo without creating a netns first. This causes issue with other tests. Fix this by using a different hook (lsm.s/file_open) and not messing with lo. 2. cgroup_xattr/read_cgroupfs_xattr sets up cgroups without proper mount namespaces.

2025-06-27selftests: forwarding: lib: Split setup_wait()Petr Machata4-5/+10
setup_wait() takes an optional argument and then is called from the top level of the test script. That confuses shellcheck, which thinks that maybe the intention is to pass $1 of the script to the function, which is never the case. To avoid having to annotate every single new test with a SC disable, split the function in two: one that takes a mandatory argument, and one that takes no argument at all. Convert the two existing users of that optional argument, both in Spectrum resource selftest, to use the new form. Clean up vxlan_bridge_1q_mc_ul.sh to not pass a now-unused argument.

genelf is the only file in perf that depends on libcrypto (or openssl) which only calculates a Build ID (SHA1, MD5, or URANDOM). SHA1 was expected to be the default option, but MD5 was used by default due to previous issues when linking against Java. This commit switches genelf to use the in-house sha1(), and also removes MD5 and URANDOM options since we have a reliable SHA1 implementation to rely on.

And make builtin-trace.c less conditional. Dummy functions will be called when BUILD_BPF_SKEL=0 is used. This makes the builtin-trace.c slightly smaller and simpler by removing the skeleton and its helpers. The conditional guard of trace__init_syscalls_bpf_prog_array_maps() is changed from the HAVE_BPF_SKEL to HAVE_LIBBPF_SUPPORT as it doesn't have a skeleton in the code directly. And a dummy function is added so that it can be called unconditionally. The function will succeed only if the both conditions are true. Do not include trace_augment.h from the BPF code and move the definition of TRACE_AUG_MAX_BUF to the BPF directly.

2025-06-26perf test: Change all remaining #!/bin/sh to #!/bin/bashJames Clark43-43/+43
There are 43 instances of posix shell tests and 35 instances of bash. To give us a single consistent language for testing in, replace all #!/bin/sh to #!/bin/bash. Common sources that are included in both different shells will now work as expected. And we no longer have to fix up bashisms that appear to work when someone's system has sh symlinked to bash, but don't work on other systems that have both shells installed. Although we could have chosen sh, it's not backwards compatible so it wouldn't be possible to bulk convert without re-writing the existing bash tests. Choosing bash also gives us some nicer features including 'local' variable definitions and regexes in if statements that are already widely used in the tests. It's not expected that there are any users with only sh available due to the large number of bash tests that exist.

Negative tests pass various incorrect strings to the kfuncs and check for the expected error codes: -E2BIG when passing too long strings -EFAULT when trying to read inaccessible kernel memory -ERANGE when passing userspace pointers on arches with non-overlapping address spaces A majority of the tests use the RUN_TESTS helper which executes BPF programs with BPF_PROG_TEST_RUN and check for the expected return value. An exception to this are tests for long strings as we need to memset the long string from userspace (at least I haven't found an ergonomic way to memset it from a BPF program), which cannot be done using the RUN_TESTS infrastructure.

2025-06-26selftests/bpf: Allow macros in __retvalViktor Malik3-23/+19
Allow macro expansion for values passed to the `__retval` and `__retval_unpriv` attributes. This is especially useful for testing programs which return various error codes. With this change, the code for parsing special literals can be made simpler, as the literals are defined via macros. The only exception is INT_MIN which expands to (-INT_MAX -1), which is not single number and cannot be parsed by strtol. So, we instead use a prefixed literal _INT_MIN in __retval and handle it separately (assign the expected return to INT_MIN). Also, strtol cannot handle the "ll" suffix so change the value of POINTER_VALUE from 0xcafe4all to 0xbadcafe.

2025-06-26LoongArch: Replace __ASSEMBLY__ with __ASSEMBLER__ in headersThomas Huth1-2/+2
While the GCC and Clang compilers already define __ASSEMBLER__ automatically when compiling assembler code, __ASSEMBLY__ is a macro that only gets defined by the Makefiles in the kernel. This is bad since macros starting with two underscores are names that are reserved by the C language. It can also be very confusing for the developers when switching between userspace and kernelspace coding, or when dealing with uapi headers that rather should use __ASSEMBLER__ instead. So let's now standardize on the __ASSEMBLER__ macro that is provided by the compilers. This is almost a completely mechanical patch (done with a simple "sed -i" statement), with one comment tweaked manually in the arch/loongarch/include/asm/cpu.h file (it was missing the trailing underscores).
