I presume you're using some hardware (I'm guessing Mellanox?) that can actually do TLS offload? Unfortunately, I don't have any hardware that can do this, so I can't test the tls_device stuff. > From a quick look at the patch, it's not clear to me what's going wrong. > Please let us know of any helpful information that we can provide to help in > the debug. Can you find out what source line this corresponds to? RIP: 0010:skb_splice_from_iter+0x102/0x300 Assuming you're building your own kernel, something like the following might do the trick: echo "RIP: 0010:skb_splice_from_iter+0x102/0x300" | ./scripts/decode_stacktrace.sh /my/built/vmlinux /my/build/tree if you run it in the kernel source tree you're using and substitute the paths to vmlinux and the build tree for modules.
