[PATCH bpf 0/3] libbpf/selftests syscall wrapper fixes for RISC-V

Posted by Björn Töpel 2 years, 2 months ago

From: Björn Töpel <bjorn@rivosinc.com>

Commit 08d0ce30e0e4 ("riscv: Implement syscall wrappers") introduced
some regressions in libbpf, and the kselftests BPF suite, which are
fixed with these three patches.

Note that there's an outstanding fix [1] for ftrace syscall tracing
which is also a fallout from the commit above.
