John-Mark Gurney 08fca7a56b Add some new modes to OpenCrypto. These modes are AES-ICM (can be used ... for counter mode), and AES-GCM. Both of these modes have been added to the aesni module. Included is a set of tests to validate that the software and aesni module calculate the correct values. These use the NIST KAT test vectors. To run the test, you will need to install a soon to be committed port, nist-kat that will install the vectors. Using a port is necessary as the test vectors are around 25MB. All the man pages were updated. I have added a new man page, crypto.7, which includes a description of how to use each mode. All the new modes and some other AES modes are present. It would be good for someone else to go through and document the other modes. A new ioctl was added to support AEAD modes which AES-GCM is one of them. Without this ioctl, it is not possible to test AEAD modes from userland. Add a timing safe bcmp for use to compare MACs. Previously we were using bcmp which could leak timing info and result in the ability to forge messages. Add a minor optimization to the aesni module so that single segment mbufs don't get copied and instead are updated in place. The aesni module needs to be updated to support blocked IO so segmented mbufs don't have to be copied. We require that the IV be specified for all calls for both GCM and ICM. This is to ensure proper use of these functions. Obtained from: p4: //depot/projects/opencrypto Relnotes: yes Sponsored by: FreeBSD Foundation Sponsored by: NetGate		2014-12-12 19:56:36 +00:00
