[PATCH 5.15 161/371] selftests/bpf: Fix a fd leak in an error path in network_helpers.c

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Martin KaFai Lau <martin.lau@xxxxxxxxxx>

[ Upstream commit 226efec2b0efad60d4a6c4b2c3a8710dafc4dc21 ]

In __start_server, it leaks a fd when setsockopt(SO_REUSEPORT) fails.
This patch fixes it.

Fixes: eed92afdd14c ("bpf: selftest: Test batching and bpf_(get|set)sockopt in bpf tcp iter")
