My team spotted a new degradation in TLS TX device offload, bisected

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?

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
Hi,
It's:
RIP: 0010:skb_splice_from_iter (/usr/linux/net/core/skbuff.c:6957)
which coresponds to this line:
if (WARN_ON_ONCE(!sendpage_ok(page)))
Hi David,
Any other debug information that we can provide to progress with the
analysis?
