* cluster/afr: Handle transient parent-entry xactions in lookupPranith Kumar K2012-04-192-6/+96
| | | | | | | | | | | | | | | | | | | | | | | | | This patch addresses the case when the lookup on an entry is performed while it is being renamed. The lookup can possibly return 2 different gfids when lookup on one subvol reached before rename and on other after rename. In such cases the conflicting entry self-heal is triggered to resolve the issue, but if there are lot entry transactions going on the parent directory of the entry then the non-blocking locks could fail resulting in EIO. To avoid this, lookup queries locks xlator if there are any parent-entrylk on entry's basename. If afr finds that there are such locks and gfids are differing then it chooses the file with latest ctime as the iatt of the entry. This solution is not foolproof, but it decreases the probability of hitting the EIO. The correct solution is to take blocking locks on the parent-entry to find out the correct source. Taking blocking locks in lookup is not good. One stale entry lock can hang the whole filesystem. So we chose to go with this for now.

* Replace GPLV3 MD5 with OpenSSL MD5Kaleb KEITHLEY2012-04-042-11/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.)
