[PATCH v3] sefltests: net: Add on/off checks for network interface non fixed features

[PATCH v2] selftests/vDSO: fix clang build errors and warnings

by John Hubbard

When building with clang, via: make LLVM=1 -C tools/testing/selftests ...there are several warnings, and an error. This fixes all of those and allows these tests to run and pass. 1. Fix linker error (undefined reference to memcpy) by providing a local version of memcpy. 2. clang complains about using this form: if (g = h & 0xf0000000) ...so factor out the assignment into a separate step. 3. The code is passing a signed const char* to elf_hash(), which expects a const unsigned char *. There are several callers, so fix this at the source by allowing the function to accept a signed argument, and then converting to unsigned operations, once inside the function. 4. clang doesn't have __attribute__((externally_visible)) and generates a warning to that effect. Fortunately, gcc 12 and gcc 13 do not seem to require that attribute in order to build, run and pass tests here, so remove it.

[PATCH net-next 1/2] selftests: openvswitch: fix action formatting

by Adrian Moreno

In the action formatting function ("dpstr"), the iteration is made over the nla_map, so if there are more than one attribute from the same type we only print the first one.

[PATCH 0/5] ALSA: some driver fixes for control input validations

by Takashi Iwai

Hi, this is a patch set as a follow up of the thread about the errors reported by kselftest mixer-test. It changes HD-audio and vmaster control behavior to return -EINVAL for invalid input values. There is a change in kselftest itself to skip the write tests for volatile controls, too. It's for the channel map controls that can't hold the stable values.
