Subject: [PATCH net 0/5] net: tls: break the connection after a burst of empty data records
Date: Mon,  9 Nov 2026 09:58:31 -0800	[thread overview]
Message-ID: <20261109175836.1246840-1-kuba@kernel.org> (raw)

Deal with overload of zero-length TLS records. 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
