Hi,

The updated patch below addresses the issues raised by sashiko-bot.  The closed
socket and signal handling code was added to tcp_bpf_recvmsg(), and the fix was
updated to work for sockets with SO_RCVTIMEO set.

Please let me know if any more changes are required, or if the patch would need
to be submitted some other way, I'm happy to adjust as necessary.

Thanks!

Thanks for the report.


What's your use case here? With a verdict prog attached, we'd normally

expect the data to be redirected in kernel rather than read back via

recvmsg(). Are you using SK_PASS? If so, please state that in the

commit message instead of the email body.

For our use case we never do redirect or packet operations (push, pop)
we merely use it as a mechanism to read data and possibly drop data
if it violates some policy.
