* mount/nfs: Gluster nfs crashes with subdirectory mountRajesh Amaravathi2011-09-081-1/+4
| | | | | | | | | | | | | 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.

(3) Variables which are set via function calls which may have side effects.
