Hi Herbert,
I am currently working on the template for SP800-38F key wrapping. The module
is operational and calculates what I want.
However, I have one problem I am having difficulties to track down and I am
wondering whether you could point me to the right direction.
When a caller calls
crypto_alloc_aead("kw(aes)", 0, 0);
somehow the refcount of the kernel module implementing the keywrapping is not
increased. Once can see that in lsmod where the "Used by" value remains 0.
Then when the caller deallocates the cipher handle, the refcount is -1
according to lsmod. With that, a second invocation of crypto_alloc_aead will
fail and I even cannot remove the module from the kernel.
Who increases the refcount on the kernel crypto API side?
Thanks a lot
