Replace GPLV3 MD5 with OpenSSL MD5
Ric asked me to look at replacing the GPL licensed MD5 code with
something better, i.e. perhaps faster, and with a less restrictive
license, etc. So I took a couple hour holiday from working on
wrapping up the client_t and did this.
OpenSSL (nee SSLeay) is released under the OpenSSL license, a BSD/MIT
style license. OpenSSL (libcrypto.so) is used on Linux, OS X and *BSD,
Open Solaris, etc. IOW it's universally available on the platforms we
care about. It's written by Eric Young (eay), now at EMC/RSA, and I
can say from experience that the OpenSSL implementation of MD5 (at least)
is every bit as fast as RSA's proprietary implementation (primarily
because the implementations are very, very similar.) The last time I
surveyed MD5 implementations I found they're all pretty much the same
speed.
I changed the APIs (and ABIs) for the strong and weak checksums.
Strictly speaking I didn't need to do that. They're only called on
short strings of data, i.e. pathnames, so using int32_t and uint32_t
is ostensibly okay. My change is arguably a better, more general API
for this sort of thing. It's also what bit me when gerrit/jenkins
validation failed due to glusterfs segv-ing. (I didn't pay close enough
attention to the implementation of the weak checksum. But it forced me
to learn what gerrit/jenkins are doing and going forward I can do better
testing before submitting to gerrit.)
Now resubmitting with a BZ
