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 |

src/tests: The FreeBSD test suite
=================================
This file describes the build infrastructure of the FreeBSD test suite.
If you are only interested in using the test suite itself, please refer
to tests(7) instead.
The build of the test suite is organized in the following manner:
* The build of all test artifacts is protected by the MK_TESTS knob.
The user can disable these with the WITHOUT_TESTS setting in
src.conf(5).
* The goal for /usr/tests/ (the installed test programs) is to follow
the same hierarchy as /usr/src/ wherever possible, which in turn drives
several of the design decisions described below. This simplifies the
discoverability of tests. We want a mapping such as:
/usr/src/bin/cp/ -> /usr/tests/bin/cp/
/usr/src/lib/libc/ -> /usr/tests/lib/libc/
/usr/src/usr.bin/cut/ -> /usr/tests/usr.bin/cut/
... and many more ...
* Test programs for specific utilities and libraries are located next
to the source code of such programs. For example, the tests for the
src/lib/libcrypt/ library live in src/lib/libcrypt/tests/. The tests/
subdirectory is optional and should, in general, be avoided.
* The src/tests/ hierarchy (this directory) provides generic test
infrastructure and glue code to join all test programs together into
a single test suite definition.
* The src/tests/ hierarchy also includes cross-functional test programs:
i.e. test programs that cover more than a single utility or library
and thus don't fit anywhere else in the tree. Consider this to follow
the same rationale as src/share/man/: this directory contains generic
manual pages while the manual pages that are specific to individual
tools or libraries live next to the source code.
In order to keep the src/tests/ hierarchy decoupled from the actual test
programs being installed --which is a worthy goal because it simplifies
the addition of new test programs and simplifies the maintenance of the
tree-- the top-level Kyuafile does not know which subdirectories may
exist upfront. Instead, such Kyuafile automatically detects, at
run-time, which */Kyuafile files exist and uses those directly.
Similarly, every directory in src/ that wants to install a Kyuafile to
just recurse into other subdirectories reuses this Kyuafile with
auto-discovery features. As an example, take a look at src/lib/tests/
whose sole purpose is to install a Kyuafile into /usr/tests/lib/.
The goal in this specific case is for /usr/tests/lib/ to be generated
entirely from src/lib/.
