Subject: [PATCH net v2 0/4] net: tls: net: tls: fix a few random bugs
Date: Mon, 11 May 2026 10:49:16 -0700	[thread overview]
Message-ID: <20260511174920.433155-1-kuba@kernel.org> (raw)

Fix a few random bugs, from external reports and my local scan
with various AI tools. Mostly corner cases in code which I don't
think TLS maintainers would consider "battle tested".

v2:
 - patches 2 and 3 are new (Sashiko report)
 - patch 4 is rewritten to remove the code instead of fixing it
 - drop the selftests, they were a little too specific, more PoC
   triggers than selftests, and Sashiko kept nit picking
 - old patches 1 and 2 were already applied
 - old patch 3 is gone since it can't trigger today (I will send it
   to net-next)
v1: https://lore.kernel.org/20260429222944.2139041-1-kuba@kernel.org

Jakub Kicinski (4):
  net: tls: fix off-by-one in sg_chain entry count for wrapped sk_msg
    ring
  net: tls: prevent chain-after-chain in plain text SG
  net: tls: fix use-after-free in tls_sw_sendmsg_locked after bpf
    verdict
  net: tls: remove bad rollback and UAF on ENOSPC
