[Cryptodev-linux-devel] [PATCH 1/8] introduce struct kernel_crypt_op

This struct is meant as an internal wrapper around struct crypt_op, so additional information can be passed around within the kernel module without giving userspace access to it. --- cryptodev_int.h |5 +++ cryptodev_main.c | 79 - 2 files

[Cryptodev-linux-devel] [PATCH 5/8] implement asynchronous operation mode

In order to submit a job for asynchronous completion, one uses the ioctl CIOCASYNCCRYPT, which is syntactically equal to CIOCCRYPT. But, the former will return immediately, the result has to be fetched later using CIOCASYNCFETCH (which will always return the first completed job, asking for a speci
