This is the next iteration of Chuck's series. I tried to make it as simple as possible - break the connection if sender floods us with zero-length records. Consume / discard those records even on PEEK to avoid infinite rx_list growth. https://lore.kernel.org/20261019-tls-follow-on-v6-0-ab01c4ecca0c@kernel.org Chuck Lever (3): tls: Consume empty data records in tls_sw_splice_read() selftests: tls: Skip the zero_len tests when TLS is unavailable selftests: tls: Extend coverage for zero-length records Jakub Kicinski (2): tls: break the connection after a burst of empty data records selftests: tls: Cover the cap on consecutive empty records include/net/tls.h | 1 + net/tls/tls_sw.c | 77 ++++--- tools/testing/selftests/net/tls.c | 348 ++++++++++++++++++++++++++++-- 3 files changed, 385 insertions(+), 41 deletions(-) -- 2.56.0
