[PATCH] selftests/seccomp: Unconditionally define seccomp_metadata

by Luke Nowakowski-Krijger

There are conflicts between glibc system headers sys/ptrace.h and linux/ptrace.h that can likely cause seccomp_metadata not be defined depending on what version versions are installed, leading to compile errors. A solution to make this test more resitant to these system header differences is to rely on defintions inside of the file by unconditionally defining seccomp_metadata and removing the linux/ptrace.h include where a defintion of seccomp_metadata exists for certain headers.

[PATCH] selftests: net: reuseport_bpf_numa: skip nodes not available

by Kleber Sacilotto de Souza

In some platforms the numa node numbers are not necessarily consecutive, meaning that not all nodes from 0 to the value returned by numa_max_node() are available on the system. Using node numbers which are not available results on errors from libnuma such as: ---- IPv4 UDP ---- send node 0, receive socket 0 libnuma: Warning: Cannot read node cpumask from sysfs ./reuseport_bpf_numa: failed to pin to node: No such file or directory Fix it by checking if the node number bit is set on numa_nodes_ptr, which is defined on libnuma as "Set with all nodes the kernel has exposed to userspace".

[PATCH] testing/selftests: replace deprecated "which" with "command -v"

by Andrea Righi

As /usr/share/doc/debianutils/NEWS.Debian.gz says: * The 'which' utility will be removed in the future. Shell scripts often use it to check whether a command is available. A more standard way to do this is with 'command -v'; for example: if command -v update-icon-caches >/dev/null; then update-icon-caches /usr/share/icons/... fi '2>/dev/null' is unnecessary when using 'command': POSIX says "no output shall be written" if the command isn't found. It's also unnecessary for the debianutils version of 'which', and hides the deprecation warning. Starting with debianutils 5.4 "which" is spitting out the following warning: this version of `which' is deprecated; use `command -v' in scripts instead Start to transition from "which" to "command -v" in the selftests scripts.

[RFC 00/16] KVM: selftests: Add tests for SEV, SEV-ES, and SEV-SNP guests

by Michael Roth

These patches and are also available at: https://github.com/mdroth/linux/commits/sev-selftests-rfc1 They are based on top of v5 of Brijesh's SEV-SNP hypervisor patches[1] to allow for SEV-SNP testing and provide some context for the overall design, but the SEV/SEV-ES patches can be carved out into a separate series as needed. == OVERVIEW == This series introduces a set of memory encryption-related parameter/hooks in the core kselftest library, then uses the hooks to implement a small library for creating/managing SEV, SEV-ES, SEV-SNP guests. This library is then used to implement a basic boot/memory test that's run for all variants of SEV/SEV-ES/SEV-SNP guest types, as well as a set of SEV-SNP tests that cover various permutations of pvalidate/page-state changes. - Patches 1-7 implement SEV boot tests and should run against existing kernels - Patch 8 is a KVM changes that's required to allow SEV-ES/SEV-SNP guests to boot with an externally generated page table, and is a host kernel prequisite for the remaining patches in the series. - Patches 9-12 extend the boot tests to cover SEV-ES - Patches 13-16 extend the boot testst to cover SEV-SNP, and introduce an additional test for page-state changes. Any review/comments are greatly appreciated!

[PATCH bpf-next v2 2/2] selftests/bpf: Add tests for accessing ifindex in bpf_sk_lookup

by Mark Pashmfouroush

A new field was added to the bpf_sk_lookup data that users can access. Add tests that validate that the new ifindex field contains the right data.

[PATCH] Documentation: kunit: fix path to .kunitconfig in start.rst

by Daniel Latypov

Commit ddbd60c779b4 ("kunit: use --build_dir=.kunit as default") changed the default --build_dir, which had the side effect of making `.kunitconfig` move to `.kunit/.kunitconfig`. However, the first few lines of kunit/start.rst never got updated, oops. Fix this by telling people to run kunit.py first, which will automatically generate the .kunit directory and .kunitconfig file, and then edit the file manually as desired.
