--- Comment #1 from Mark Johnston <ma...@freebsd.org> ---
I believe this is a bug in kgssapi code. aes_checksum() and aes_encrypt_1()
can observe that CRYPTO_F_DONE is set before the callback worker thread has had
a chance to invoke the callback. Then the code frees the request, i.e., there
is a use-after-free.
kgssapi is ok with synchronous implementations of crypto routines, but not with
async implementations like QAT. So the workaround for now is simply to not use
QAT. I can provide a patch for testing, but I can't provide a truenas build.
