[PATCH] selftests/net: Use kselftest skip code for skipped tests

by Po-Hsu Lin

There are several test cases in the net directory are still using exit 0 or exit 1 when they need to be skipped. Use kselftest framework skip code instead so it can help us to distinguish the return status. Criterion to filter out what should be fixed in net directory: grep -r "exit [01]" -B1 | grep -i skip This change might cause some false-positives if people are running these test scripts directly and only checking their return codes, which will change from 0 to 4. However I think the impact should be small as most of our scripts here are already using this skip code. And there will be no such issue if running them with the kselftest framework.

[PATCH] selftests: openat2: Fix testing failure for O_LARGEFILE flag

When running the openat2 test suite on ARM64 platform, we got below failure, since the definition of the O_LARGEFILE is different on ARM64. So we can set the correct O_LARGEFILE definition on ARM64 to fix this issue.

[PATCH bpf-next 0/5] bpf: implement variadic printk helper

by Dave Marchevsky

This series introduces a new helper, bpf_trace_vprintk, which functions like bpf_trace_printk but supports > 3 arguments via a pseudo-vararg u64 array. A libbpf convienience macro, bpf_vprintk, is added to support true vararg calling style. Helper functions and macros added during the implementation of bpf_seq_printf and bpf_snprintf do most of the heavy lifting for bpf_trace_vprintk. There's no novel format string wrangling here. Usecase here is straightforward: Giving BPF program writers a more powerful printk will ease development of BPF programs, particularly during debugging and testing, where printk tends to be used. Hypothetically libbpf's bpf_printk convenience macro could be modified to use bpf_trace_vprintk under the hood. This patchset does not attempt to do this, though, nor am I confident that it's desired. This feature was proposed by Andrii in libbpf mirror's issue tracker [1].
