Hi Stephan,
If we add sendmsg() in between 2 accept calls then the setkey problem
will happen?
handle->opfd = accept(handle->tfmfd, NULL, 0);
sendmsg()
handle->opfd = accept(handle->opfd, NULL, 0);
sendmsg()
handle->opfd = accept(handle->opfd, NULL, 0);
If yes, Then may be it is expected behavio

Hi Stephan,
I tried your patch on my machine. Kernel is not crashing. The openssl
break with this. Can you share HMAC program which you are suspecting
it will not work or do you already have some test written in
libkcapi/test.sh which will fail.

The strace is enlightening.
The user space code does an accept on an already accepted FD
Hi Stephan,
I tried 1 more patch. This time result is correct. Find attached patch

Hi Stephan,
I also tried test program in libkcapi and it works. libkcapi opens
socket of type "hmac(sha1)" .Openssl opens multiple "sha1" type socket
and uses the partial results to calculate hmac.
"crypto_ahash_init()" function initialises the *tfm variable in
crypto_shash structure.It gets cal

Hi,
When trying to calculate HMAC(SHA1) with openssl using af-alg engine
kernel crashes.Find below the command used and kernel. I have added
some debug print in logs.
Command used : ./openssl dgst -engine af_alg -sha1 -hmac "key" r.txt
kernel version : 3.17.8
