From: Gal Pressman <gal@nvidia.com> stable inclusion from stable-v5.10.137 commit 1f7ffdea19f2fe38179d7ae2c0c6d8182e874308 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I60PLB Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit 115d9f95ea7ab780ef315dc356bebba2e07cb731 ] The driver reports whether TX/RX TLS device offloads are supported, but not which ciphers/versions, these should be handled by returning -EOPNOTSUPP when .tls_dev_add() is called. Remove the WARN_ON kernel trace when the driver gets a request to offload a cipher/version that is not supported as it is expected.
