* performance/readdir-ahead: indicate EOF for readdirpRaghavendra Bhat2014-12-171-2/+9
| | | | | | | | | | | | | | | | | | posix xlator sends op_errno as ENOENT and op_ret as 0, to indicate readdir has been completed. readdir-ahead should send that op_errno that it has saved in the fd context, when it serves the readdir requests. Otherwise some xlators sitting above performance xlators such as snapview-client, which checks for end of readdir operation by checking op_ret to 0 and op_errno to ENOENT will not be able to identify end of readdir.

* telldir()/seekdir() portability fixesEmmanuel Dreyfus2014-12-179-31/+137
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | POSIX says that an offset obtained from telldir() can only be used on the same DIR *. Linux is abls to reuse the offset accross closedir()/opendir() for a given directory, but this is not portable and such a behavior should be fixed. An incomplete fix for the posix xlator was merged in http://review.gluster.com/8926 This change set completes it. - Perform the same fix index xlator. - Use appropriate casts and variable types so that 32 bit signed offsets obtained by telldir() do not get clobbered when copied into 64 bit signed types. - modify glfs-heal.c and afr-self-heald.c so that they do not use anonymous fd, since this will cause closedir()/opendir() between each syncop_readdir(). On failure we fallback to anonymous fs only for Linux so that we can cope with updated client vs not updated brick. - Avoid sending an EINVAL when the client request for the EOF offset. Here we fix an error in previous fix for posix xlator: since we fill each directory entry with the offset of the next entry, we must consider as EOF the offset of the last entry, and not the value of telldir() after we read it. - Add checks in regression tests that we do not hit cases where offsets fed to seekdir() are wrong. Introduce log_newer() shell function to check for messages produced by the current script. This fix gather changes from http://review.gluster.org/9047 and http://review.gluster.org/8936 making them obsolete.

* fuse: protect checking/modifying graph->used with a mutexNiels de Vos2014-12-121-3/+9
| | | | | | | | | | | | | | | | | | While reviewing http://review.gluster.org/#/c/9060/ we noticed that fuse checks/modifies graph->used in a unlocked way. There is a potential race in case when fuse_graph_setup() gets called from two different threads (currently unlikely, but poller/notify() might change in future?). In libgfapi we came to the conclusion that each glfs structure can be used to protect the checking/updating of graph->used. In fuse this would be the fuse_private_t with sync_mutex.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | table problem: USS allows split-brain file to be accessed while main volume gives I/O error. cause: AFR detects split-brain on lookup. It stores this information in inode context. open and readv fop checks this flag from inode context. open and readv fop fails if split-brain flag is set for the file. USS uses gfapi to access snapshot volume. During open call gfapi internally calls glfs_resolve_component. glfs_resolve_component generates a new inode even if inode is present for the file. Because of which afr_lookup acts on a new inode which does not contain the split-brain flag.

Self healing is executed in background, allowing the fop that detected the problem to continue without blocks nor delays. While this is quite interesting to avoid unnecessary delays, it can cause spurious failures of self-heal because it may try to recover a file inside a directory that a previous self-heal has not recovered yet, causing the file self-heal to fail. 2. When a partial self-heal is being executed on a directory, if a full self-heal is attempted, it won't be executed because another self-heal is already in process, so the directory won't be fully repaired. 3. Information contained in loc's of some fop's is not enough to do a complete self-heal. To solve these problems, I've made some changes: * Improved ec_loc_from_loc() to add all available information to a loc. * Before healing an entry, it's parent is checked and partially healed if necessary to avoid failures. * All heal requests received for the same inode while another self-heal is being processed are queued. When the first heal completes, all pending requests are answered using the results of the first heal (without full execution), unless the first heal was a partial heal. In this case all partial heals are answered, and the first full heal is processed normally. * An special virtual xattr (not physically stored on bricks) named 'trusted.ec.heal' has been created to allow synchronous self-heal of files. Now, the recommended way to heal an entire volume is this: find <mount> -d -exec getfattr -h -n trusted.ec.heal {} \; Some minor changes: * ec_loc_prepare() has been renamed to ec_loc_update(). * All loc management functions return 0 on success and -1 on error. * Do not delay fop unlocks if heal is needed. * Added basic ec xattrs initially on create, mkdir and mknod fops. * Some coding style changes Change-Id: I2a5fd9c57349a153710880d6ac4b1fa0c1475985 BUG: 1161588 Signed-off-by: Xavier Hernandez <xhernandez@datalab.es> Reviewed-on: http://review.gluster.org/9072 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Dan Lambright <dlambrig@redhat.com>

| | | | | | | | | | | | | | | | | | | | Final test in basic/afr/resolve.t checks for a failure after breaking the backend. But since the tested file was accessed just before that operations, it may still be in kernel page cache. As a result, file read is handled by kernel cache and never sent to the filesystem, and the test is successful where it should have failed. Fix this by waiting 10s before reading the supposed-to-be-broken file.

* Glusterfs/posix: Stack corruption in posix_handle_pumpNithya Balachandran2014-12-031-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | posix_handle_pump can corrupt the stack if the buffer passed to it is too small to hold the final path. Fix : Check if the buffer is sufficiently large to hold the new path component before modifying it. This will prevent the buffer overrun but the path returned will most likely have too many symbolic links causing subsequent file ops to fail with ELOOP. The callers of this function do not currently check the return value. The code needs to be modified to have all callers check the return value and take appropriate action in case of an error.

| | | | | | | | | | | | | | | | | | | | | | | | | In glusterd_op_sm(), we lock and unlock the gd_op_sm_lock mutex. Unfortunately, locking and unlocking can happen in different threads (task swap will occur in handler call with use of synctasks). This case is explictely covered by POSIX: the behavior is undefined. http://pubs.opengroup.org/onlinepubs/9699919799/functions/pthread_mutex_lock.html When unlocking from a thread that is not owner, Linux seems to be fine (though you never know with unspecified operation), while NetBSD returns EPERM, causing a spurious error in tests/basic/pump. To fix this, we use synclock_t which was precisely meant for this. synclock is a pthread_mutex_t like synchronization object which uses the synctask handle for owner and is immune to the task being run on multiple threads during its lifetime.
