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 TAG: IPSEC-HEAD Issue: #4841

* MFC 267291:jhb2014-06-272-4/+4
| | | | | | | | | Use strcasecmp() instead of strcmp() when checking user-supplied encoding names so that encoding names are treated as case-insensitive. This allows the use of 'utf-8' instead of 'UTF-8' for example and matches the behavior of iconv(1). PR: 167977

* Use strchr() and strrchr().ed2012-01-021-2/+2
| | | | | | | | It seems strchr() and strrchr() are used more often than index() and rindex(). Therefore, simply migrate all kernel code to use it. For the XFS code, remove an empty line to make the code identical to the code in the Linux kernel.
* Remove the now unused skpc() function.ed2012-01-011-49/+0
| | | | | | | | | It was only used by ufs and ext2 and I have really strong doubts that there are other pieces of code that also use this function. If it turns out that external drivers use this code as well, I'd be happy to migrate or revert. Bump __FreeBSD_version while there.
* Introducing memcchr(3).ed2012-01-011-0/+115
| | | | | | | | | | | | | | | | | | | | | It seems two of the file system drivers we have in the tree, namely ufs and ext3, use a function called `skpc()'. The meaning of this function does not seem to be documented in FreeBSD, but it turns out one needs to be a VAX programmer to understand what it does. SPKC is an instruction on the VAX that does the opposite of memchr(). It searches for the non-equal character. Add a new function called memcchr() to the tree that has the following advantages over skpc(): - It has a name that makes more sense than skpc(). Just like strcspn() matches the complement of strspn(), memcchr() is the complement of memchr(). - It is faster than skpc(). Similar to our strlen() in libc, it compares entire words, instead of single bytes. It seems that for this routine this yields a sixfold performance increase on amd64. - It has a man page.
