* nfs3: Resolve entry vs. hash conflict at same dir depthShehjar Tikoo2011-09-071-15/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* nfs: opendir/closedir for every readdirAnand Avati2010-11-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Revert "nfs3: Unref & unbind dir fd with inode lock on EOF" This reverts commit 4e6fb304ce41acbaf7c9ba67c06bf443e65082e8. The above commit (which unbinds fds at EOF) does not fix the original bug (1619) because a readdir from a second app could have already started before the readdir_cbk of the first app's readdir reaches NFS code. Hence the race still exists. Performing extra unrefs when EOF is received is not a reliable way of detecting that a client has performed a closedir (and to close the fd ourselves). Neither is interpreting a 0 cookies a new opendir. Clients can always use telldir/seekdir and hit EOFs twice. Due to the way NFS3 protocol is designed, it is just not possible for the server to reliably detect opendirs/closedirs performed by the client and map the corresponding readdirs to the same dir fd on the server side. The only reliable way of fixing this is to perform opendir/closedir at the cost of performance. Any optimization towards keeping dir fds open attempting to map them with application's opendir/closedir will either result in fd leaks or extra fd unrefs. Signed-off-by: Anand V.

| | | | | | | | | | | | | | | | | | | | | | | | | Suppose a file name 1 is created and some data is written to it. After this another 512 files are newly created and written to. When the the 513th file is created and an fd_t opened for it, it results in 1's fd_t being replaced in the fd-lru with 513th file's fd_t. This is the correct behaviour resulting in all refs getting unref from the fd_t of 1 and the fd and all related state being freed. But, in some workloads, some refs are still pending even after the fd_t is removed from LRU, resulting in the fd still being bound to the inode. In nfs3svc_remove_cbk, while removing the inode state, we also ensure that any fd_ts in the cache for this inode are also removed. While removing the fd_t, this situation where the fd_t has replaced with another, even while a ref remains on the fd_t, results in a crash in the fdcache_remove path in nfs3svc_remove_cbk. This happens because the fd_ctx_get results in a NULL value because the ctx was already deleted when this fd_t was removed from fd-lru earlier. This patch fixes the crash by introducing a NULL check.

* nfs3: Fix race updating op queue on uncached fd openShehjar Tikoo2010-07-061-55/+150
| | | | | | | | | | | | | The order of locking while performing async fd opens was resulting in a deadlock when a particular pattern of operations was generated by compilebench. This patch improves handling of those situations while locking the fd-cache, inode and inode queue. Signed-off-by: Shehjar Tikoo <shehjart@gluster.com> Signed-off-by: Anand V.
