[PATCH net-next v7 0/3] netdev-genl: Add an xsk attribute to queues

by Joe Damato

Greetings: Welcome to v7. Added CONFIG_XDP_SOCKETS to the selftests/driver/net kernel config in patch 3. Updated the xdp_helper.c to return -1 on AF_XDP non-existence, and updated queues.py to skip the test if AF_XDP does not exist (but fail in other failure cases). Tested on kernels with and without CONFIG_XDP_SOCKETS enabled. This is an attempt to followup on something Jakub asked me about [1], adding an xsk attribute to queues and more clearly documenting which queues are linked to NAPIs... After the RFC [2], Jakub suggested creating an empty nest for queues which have a pool, so I've adjusted this version to work that way. The nest can be extended in the future to express attributes about XSK as needed. Queues which are not used for AF_XDP do not have the xsk attribute present. I've run the included test on: - my mlx5 machine (via NETIF=) - without setting NETIF And the test seems to pass in both cases.

[PATCH net-next v6 0/3] netdev-genl: Add an xsk attribute to queues

Greetings Welcome to v6. Added ifdefs to patch 2 and built with CONFIG_XDP_SOCKETS both enabled and disabled to confirm it builds cleanly. No other changes.

[PATCH v2 1/2] selftests/bpf: Define SYS_PREFIX for powerpc

Since commit 7e92e01b7245 ("powerpc: Provide syscall wrapper") landed in v6.1, syscall wrapper is enabled on powerpc. Commit 94746890202c ("powerpc: Don't add __powerpc_ prefix to syscall entry points") , that drops the prefix to syscall entry points, also landed in the same release.

[PATCH v4] selftests: tpm2: test_smoke: use POSIX-conformant expression operator

by Ahmed Salem

Use POSIX-conformant expression operator symbol '='. 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. Instead of changing the shebang to use bash, which may not be available on all systems, use the POSIX-conformant expression symbol '=' to test for equality.
