Hello,
This series adds helper functions for testing AF_ALG (the userspace
interface to algorithms in the Linux kernel's crypto API) to the
Linux Test Project. It then adds a few sample regression tests.
I've had these patches sitting around for a while with the goal of also
writing some "real" tests that test for more than these specific bugs,
but haven't gotten around to it yet. And I now consider further
improving the in-kernel crypto self-tests to be a higher priority. But
I figured I'd send this out as-is in case people are interested in
having this merged, e.g. maybe other people want to add AF_ALG tests to
LTP too and the 'tst_af_alg' lib would be a good starting point.
Changed since v1:
- Define 'AF_ALG' in include/lapi/socket.h if undefined.
Also move 'SOL_ALG' definition to there.
- Add all new tests to runtest/crypto.
- In af_alg01, use .test() and .tcnt rather than a 'for' loop.
- Consistently use 'algfd' rather than 'alg_fd', and similarly for reqfd.
- Make two error messages in tst_af_alg.c clearer.
- Add SPDX license identifier to include/lapi/if_alg.h.
