* Replace GPLV3 MD5 with OpenSSL MD5Kaleb KEITHLEY2012-04-041-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.)

* nfs: do not call inode_path on the newly created inodeRaghavendra Bhat2012-03-141-5/+18
| | | | | | | | | | | | | | | | | | | | | | While resolving, for building the path into the loc, inode_find is called with gfid as argument to get the inode from the inode table. If the inode is not found, then a new inode is created. Then the path is build using inode_path. But if the inode is not linked to inode table (newly created inode), then gfid will be null and inode_path returns null gfid as the path. Suppose the lookup operation on that gfid fails, then we print the null gfid in the log message. To avoid it, build the path using the gfid only if inode_path fails.

* glusterd: auth allow enhancementsRajesh Amaravathi2012-02-201-1/+1

E.g: volume vol in a cluster of two peers: /mnt/brick1 in 192.168.1.4 /mnt/brick2 in 192.168.1.5 option auth.allow 192.168.1.6 (allow connection requests only from 192.168.1.6) This will disrupt the nfs servers on 192.168.1.{4,5}. brick server processes reject connection requests from both nfs servers (on 4,5), because the peer addresses are not in the auth.allow list. Same holds true for local mounts (on peer machines), self-heal daemon, and other operations which perform a glusterfs mount on one of the peers. * SOLUTION: Login-based authentication (username/password pairs, henceforth referred to as "keys") for gluster services and operations. These *per-volume* keys can be used to by-pass the addr-based authentication, provided none of the peers' addresses are put in the auth.reject list, to enable gluster services like gNfs, self-heal daemon and internal operations on volumes when auth.allow option is exercised. * IMPLEMENTATION: 1. Glusterd generates keys for each volume and stores it in memory as well as in respective volfiles. A new TRUSTED-FUSE volfile is generated which is fuse volfile + keys in protocol/client, and is named trusted-<volname>-fuse.vol. This is used by all local mounts. ANY local mount (on any peer) is granted the trusted-fuse volfile instead of fuse volfile via getspec. non-local mounts are NOT granted the trusted fuse volfile. 2. The keys generated for the volume is written to each server volfile telling servers to allow users with these keys. 3. NFS, self-heal daemon and replace-brick volfiles are updated with the volume's authentication keys. 4. The keys are NOT written to fuse volfiles for obvious reasons. 5. The ownership of volfiles and logfiles is restricted to root users. 6. Merging two identical definitions of peer_info_t in auth/addr and rpc-lib, throwing away the one in auth/addr. 7. Code cleanup in numerous places as appropriate. * IMPORTANT NOTES: 1. One SHOULD NOT put any of the peer addresses in the auth.reject list if one wants any of the glusterd services and features such as gNfs, self-heal, rebalance, geo-rep and quota. 2. If one wants to use username/password based authentication to volumes, one shall append to the server, nfs and shd volfiles, the keys one wants to use for authentication, *while_retaining those_generated_by_glusterd*. See doc/authentication.txt file for details.

| | | | | | | | | | | | | Glusterfs used to crash trying to dereference a NULL pointer. Also, in mnt3_resolve_export_subdir, volume name was prefixed to sub directory exported, resulting in mount fail of sub directory. Fixed both issues.

* nfs3: Resolve entry vs. hash conflict at same dir depthShehjar Tikoo2011-09-072-15/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Intro Note ========== The current code in hard fh resolution takes the first-match approach, i.e. which ever dirent either matches the hash or matches the gfid first is the one chosen as the result for the next step of fh resolution. In the latter case, i.e., dirent matches the gfid, we the next step is to conclude the fh resolution by returning the entry whose gfid matched. In the former, i.e., the hash matches the dirent, we choose the hash-matching dirent as the next directory to descend into, for searching the file to be operated upon. Problem ======= When performing hard fh resolution, there can be a situation where: o the hash of the primary entry,i.e. the entry we're looking for and the hash of another sibling directory, match. Note the use of "sibling", meaning both the primary entry and the hash matching one are in the same directory, i.e., their filehandle.hashcount will be same. o the sibling directory is encountered first during the dir search. Because of the current code described in "Intro", we'll end up descending into the sibling directory even though the correct behaviour is to ignore this and wait till we encounter the primary entry in the same parent directory. Once we end up descending into this sibling directory, the directory depth validation check fails. The check fails because it notices that the resolution is attempting to open a directory that is deeper in the fs tree than the file we're looking for. When this check fails, we return an ESTALE. So basically, a false-positive results in an estale to Specsfs. This is not a theoretical situation. Me and Avati saw this on specsfs test where sfs created terabytes-sized file system for its tests. The number of files was so huge in a single directory that the hashes of two entries ended up colliding.
