====================
bpf: Fix backward progress bug in bpf_iter_udp
From: Martin KaFai Lau <martin.lau@kernel.org>
This patch set fixes an issue in bpf_iter_udp that makes backward
progress and prevents the user space process from finishing. There is
a test at the end to reproduce the bug.
Please see individual patches for details.
v3:
- Fixed the iter_fd check and local_port check in the
patch 3 selftest. (Yonghong)
- Moved jhash2 to test_jhash.h in the patch 3. (Yonghong)
- Added explanation in the bucket selection in the patch 3. (Yonghong)
v2:
- Added patch 1 to fix another bug that goes back to
the previous bucket
- Simplify the fix in patch 2 to always reset iter->offset to 0
- Add a test case to close all udp_sk in a bucket while
in the middle of the iteration.
