posix/afr: handle backward compatibility for rchecksum fop

2018-02-19T14:57:12+00:00

Added a volume option 'fips-mode-rchecksum' tied to op version 4.
If not set, rchecksum fop will use MD5 instead of SHA256.

updates: #230

rchecksum/fips: Replace MD5 usage to enable fips support

2017-12-21T04:31:31+00:00

rchecksum uses MD5 which is not fips compliant. Hence
using sha256 for the same.

Replace copied (from rsync) checksum code by adler32() from zlib

2014-11-21T17:12:20+00:00

The weak checksum code that is included in libglusterfs has initialy
been copied from the rsync sources. Instead of maintaining a copy of a
function, we should use a function from a shared library. The algorithm
seems to be Adler-32, zlib provides an implementation.

The strong checksum function has already been replaced by MD5 from
OpenSSL. It is time to also remove the comments about the origin of the
implementation, because it is not correct anymore.

Replace GPLV3 MD5 with OpenSSL MD5

2012-04-04T23:13:21+00:00

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
