I am running Kernel TLS with CAAM on iMX8M board. KTLS + CAAM is broken in 6.1 kernel when async and zero copy is true. **Commit id causing the issue: ** commit cbbdee9918a2662914f411aa999f2f80bf044a30 Author: Jakub Kicinski kuba@kernel.org Date: Thu Jul 14 22:22:34 2022 -0700 tls: rx: async: don't put async zc on the list The "zero-copy" path in SW TLS will engage either for no skbs or for all but last. If the recvmsg parameters are right and the socket can do ZC we'll ZC until the iterator can't fit a full record at which point we'll decrypt one more record and copy over the necessary bits to fill up the request. The only reason we hold onto the ZC skbs which went thru the async path until the end of recvmsg() is to count bytes. We need an accurate count of zc'ed bytes so that we can calculate how much of the non-zc'd data to copy. To allow freeing input skbs on the ZC path count only how much of the list we'll need to consume. Signed-off-by: Jakub Kicinski kuba@kernel.org Signed-off-by: David S. Miller davem@davemloft.net
