Subject: [PATCH bpf v1 0/2] bpf: cpumap: fix error propagation in
Date: Sat, 29 Nov 2025 01:04:53 +0900 [thread overview]
Message-ID: <20251128160504.57844-1-enjuk@amazon.com> (raw)
This series fixes incorrect error propagation in cpumap and adds
selftests that cover the failure cases.
Currently, failures returned from __cpu_map_entry_alloc() are ignored
and always converted to -ENOMEM by cpu_map_update_elem(). This series
ensures the correct error propagation and adds selftests.
Kohei Enju (2):
bpf: cpumap: propagate underlying error in cpu_map_update_elem()
selftests/bpf: add tests for attaching invalid fd
