* mount/fuse: check for fuse inval notify support when fopen-keep-cache enabledBrian Foster2012-07-181-1/+15
| | | | | | | | | | | | | | | | | The fopen-keep-cache feature relies on the fuse notification system to operate correctly. As Csaba has pointed out, the inode invalidation functionality was added in FUSE version 7.12. Require that the user have 7.12 or later to enable fopen-keep-cache. If not supported, warn the user and disable the feature.

* glusterfs_ctx_t: un-globalize the filesystem contextAnand Avati2012-07-1720-133/+121
| | | | | | | | | | | | | | | | | | | | | | | | So far there has been a global glusterfs_ctx_t object which represents the running instance of the filesystem (client or server). It contains the various graphs, connection to the management daemon over which new graphs are obtained, calls stacks issued on this filesystem, and a bunch of such things. With the introduction of libgfapi, it is no more true that there will be only one filesystem context in a process. Applications can be written to use libgfapi and obtain serveral instances of different filesystems/volumes in the same process. This involves messy untangling of assumptions inside libglusterfs that there would only be one global glusterfs_ctx_t and offload that assumption to glusterfsd/ and cli/ (where it is true).

* libglusterfs,mount/fuse: implement gidcache mechanism in fuse-bridgeBrian Foster2012-07-1714-120/+353
| | | | | | | | | | | | | | | | | | | | | | | | | | This change genericizes the cache mechanism implemented in commit 8efd2845 into libglusterfs/src/gidcache.[ch] and adds fuse-bridge as a client. The cache mechanism is fundamentally equivalent, with some minor changes: - Change cache key from uid_t to uint64_t. - Modify the cache add logic to locate and use an entry with a matching ID, should it already exist. This addresses a bug in the existing mechanism where an expired entry supercedes a newly added entry in lookup, causing repeated adds and flushing of a cache bucket. The fuse group cache is disabled by default. It can be enabled via the 'gid-timeout' fuse-bridge translator option and accompanying mount option (i.e., '-o gid-timeout=1' for a 1s entry timeout).

| | | | | | | | | | | | | | | | | | | | | | fopen-keep-cache disables unconditional page-cache invalidations on file open in fuse (via FOPEN_KEEP_CACHE) and replaces that behavior with detection of remote changes and explicit invalidations from mount/fuse. This option improves local caching through the page cache and native client. This change defines a new 'invalidate' translator callback to identify when an inode's cache mapping has been determined to be invalid. md-cache implements the policy to detect and invoke inode invalidations. fuse-bridge and io-cache implement invalidate handlers to invalidate the respective caches (page cache in the case of fuse).

GF_PROTOCOL_DICT_SERIALIZE() hacks around it by creating a size_t temp var, but that's, well, a hack, IMO when you consider that all the callers are actually passing &<u_int>; the param should just be a u_int * and eliminate the buggy casts and the temp var in the macro.

* cli: print_brick_status: don't smash stackJim Meyering2012-07-111-8/+3
| | | | | | | | | | | | | | | | | | For bricklen > 110 (i.e., 2 * fieldlen), the if-clause would be executed 2 or more times, making strncpy write past the end of "buf", clobbering the stack. Rewrite, removing unnecessary use of strncpy, strlen and decl/use of the temporary buffer, and instead, specifying precision via a printf-style format directive. Coverity identified the static buffer overrun.

* glusterd: avoid buffer overrun for over-long volnameJim Meyering2012-07-111-1/+7
| | | | | | | | | | | | | | | | | [in glusterd_store_is_valid_brickpath] When strlen(volname) is no smaller than sizeof(volinfo->volname), volinfo->volname would end up not being NUL-terminated. Then, a use of that buffer that expects it to be NUL-terminated (i.e., glusterd_store_brickinfopath_set's GLUSTERD_GET_BRICK_DIR) will access beyond the end of the buffer. Instead, diagnose the too-long volume name and fail.

* cluster/afr: cleanup lk_owner and PID messAnand Avati2012-07-043-41/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Historically PID (frame->root->pid) was used by the locks translator to identify a locker (and make decisions about which locks contend or cooperate/merge). Since the introduction of lock_owner parameter the usage of PID (for locks) was deprecated and is now unused. This patch nukes the usage of PID in AFR The usage of lk_owner has also ended up being a mess, because of the differentiation required between ->lk() and ->inodelk(), (->lk() needs to be identified by the process (roughly) and ->inodelk() needs to be identified by the transaction) and also because of optimizations like eager locking (locks are no more identified by the transaction as they now get inherited by the next transaction). The scheme (and technique) now is: - All FOPs (the third phase of the transaction) happen with the lk_owner which is set by the topmost layer (FUSE, NFS etc.) - All entrylks are issued with lk_owner set to the frame->root address. - Inodelks which will not be subject to eager locking are issued with lk_owner set to frame->root. - Inodelks which are subject to eager locking are issued with lk_owner set to the address of fd_t (which are the only type of frames which get subject to the eager locking optimization) - At the start of the transaction, the transaction frame's lk_owner is set to the either frame->root or fd_t (and never unmodified) depending on the type of transaction. - Just before the third phase (FOP phase) the set lk_owner is "saved" away and overwritten by the lk_owner submitted by the top layer (FUSE or NFS) - Right after the third phase, the saved lk_owner is "restored" to resume the transaction into the POST-OP and eventually UNLOCK using the same lk_owner which was used during the LOCK phase.
