* glusterd: Fix glusterd crash resulting from uninitialised pointerKrutika Dhananjay2012-08-021-0/+6
| | | | | | | | | | | | | | | | | | | | | | PROBLEM: glusterd crashes during replace-brick operation as the pointer old_brickinfo is dereferenced without being initialised. FIX: Have old_brickinfo initialised to point to the brick info of the brick being replaced before dereferencing it. TEST: Ran glusterd in debug mode before and after the fix; process crash ceased in the latter case.

* cluster/afr: Unwind with correct pre/post parent bufsPranith Kumar K2012-08-023-403/+147
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RCA: In case of dir fops create, mknod, mkdir, link, symlink, rename if the fop fails on read-child then unwinds are happening with all-zero pre/post iatt-bufs. The bug occurs because the parent bufs are not saved if the response is not from read-child. Fix: Save the pre/post-bufs for the first response. If the response comes from read-child, overwrite whatever we have cached. Tests: Attached the mount process to gdb. Tested that the unwinds happen with proper pre/post iatt bufs in the following cases: 1) All success case 2) Failure on read-child 3) Failure on non-read-child 4) Failure on all children. Tested soft-link self-heal to test the change made in that. Tested errno ENOTEMPTY for rmdir, rename fops.

* cluster/afr: Handle child_up & fd not opened case in xactionPranith Kumar K2012-08-011-7/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RCA: When an fd is opened while a brick is down, after the brick comes back up afr issues open on the other brick. It can fail for a number of reasons (enoent etc). While the system is in that state, inode/entrylks pre-op happen only on the brick that is up and fd is opened for fd-fops. post-op should consider only the bricks where both pre-op and fop succeeded as success, rest of them as failures. Code now marks only the children that are down as failures as opposed to child_down & fd-not-opened. This makes change-log appear as success on the subvolume where we did not do any fop leading to no change-log but differences in data/metadata for reg-files. Fix: Mark non-participants of fop as failure. This is tracked in transaction.pre_op[]. Tests: Simulated the scenario using err-gen on top of one of the client xlator which fails all fops always. Performed fops and the changelog represented pending fops on the brick with err-gen loaded. Tested the case of brick down and perform entry/metadata/data operations to confirm they still work as expected.

* protocol/client: Fix negative return in client_setvolumeKrutika Dhananjay2012-08-011-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PROBLEM: The function dict_serialized_length could, owing to an error, return a negative integer (-EINVAL) that gets assigned to an unsigned int member 'dict_len' of gf_setvolume_req structure. FIX: Hold the value returned by dict_serialized_length in local variable ret (which is a signed int). Test if ret is negative, in which case the control would anyway branch to the label fail where the function returns. Otherwise dict_len is assigned with ret, in turn giving a more meaningful value to the attribute length. TEST: Attached gdb to glusterfs mount process, set breakpoint at client_setvolume, forced dict_serialized_length to return -EINVAL (indirectly by forcing _dict_serialized_length to return -EINVAL after setting count to -1 within its body) and checked the value of ret (which is now sure to contain a negative value) whose value will be appropriately tested to decide the next course of action within client_setvolume: whether to simply exit due to an error or execute the subsequent statements.

* cluster/stripe: handle short writes and errors in writev callbackBrian Foster2012-07-303-38/+106
| | | | | | | | | | | | | | | | | | | | | | | cluster/stripe write callback handling is broken in the event of server side errors and short writes due to crudely summing up the return values from each node. This can produce incorrect results or cause an application to rewrite the wrong portions of a buffer in an attempt to handle this condition. Modify cluster/stripe writev handling to record the requested size of each write and use this data to return the number of consecutive bytes written from the original request. This allows an application to retry a write at the point of error (and potentially consume said error).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RCA The bug is observed because the decision to mark a file in split-brain is taken outside appropriate locks. Lookup gathers xattrs outside any lock. The xattrs being in split-brain in lookup should only be taken as a hint. Appropriate inodelks should be taken before confirming a split-brain. Self-heal confirms this at the moment. If data/metadata self-heal is turned off, inspecting of xattrs could not be performed so split-brain behavior does not work correctly if the self-heal options are turned off. Fix Self-heals are launched to inspect xattrs even when the data/metadata self-heal options are turned off. The decision to heal data/metadata after the xattrs are inspected is based on whether the options are turned on/off. So decision to set/reset split-brain flag is taken inside appropriate locks.

* Fixes for gsyncd / geo-rep and FUSE listxattrVenky Shankar2012-07-242-8/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes two problems with recent changes to Geo-Replication First: ------ Recent changes to geo-replication relies on Rsync to tranfer extended attributes. Essentially Rsync would invoke a listxattr() and then getxattr() the set reutrned by listxattr() and finally transfer it to the remote slave. Xattrs like security.selinux would create problems as they are not allowed to be set explicitly (unless there's a rule that allows this). So, to make Rsync behave sanely we filter out all "*.selinux*" xattrs from listxattr() (which is getxattr() with ->name as NULL). Second: ------- Python's "if {..} else {..}" shortcut ".. and .. or .." was misused here. This is a straightforward fix by interchanging last two variables (classes in this case). Also fix a typo in sendmark_regular() definition.

* FUSE: ignore setxattr for some keys from gsyncd aux mountVenky Shankar2012-07-193-0/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | Context ------- gsyncd/geo-rep plans to rely on Rsync to sync extended attributes. When this is in place, all xattrs *visible* on the mount point would be candidate for syncing. This set could include gluster internal xattrs too (as xome xlators do not filter out in their cbks). Syncing these xattrs to the slave could result in unexpected functioning of the slave mount. Soln. ----- For gsyncd auxillary mounts (identified by client_pid -1), we only allow xtime related xattrs to go through and silently ignore (w/o propagating error back to the client) the rest of them. This provides a future proof solution as we need not worry about what xattrs show up on the mounts. Also, 'user' namespace xattrs are always passed through even if it's from a gsyncd aux mount.

* glusterfs_ctx_t: un-globalize the filesystem contextAnand Avati2012-07-173-8/+6
| | | | | | | | | | | | | | | | | | | | | | | | 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).
