* acl: enable handling of FMODE_EXEC flagAmar Tumballi2012-08-131-0/+7
| | | | | | | | | | | | | | | | | | | | | | on linux systems, with open(), we can get below flag as per 'linux/fs.h'. /* File is opened for execution with sys_execve / sys_uselib */ '#define FMODE_EXEC ((fmode_t)0x20)' Instead of adding '#include <linux/fs.h>, its better to copy this absolute number into other variable because then we have to deal with declaring fmode_t etc etc.. With the fix, we can handle the file with '0711' permissions in the same way as backend linux filesystems.

* cluster: fix crash on link of named pipe in stripe/replicate volBrian Foster2012-08-132-12/+11
| | | | | | | | | | | | | | | | | | | | | | | A crash occurs when attempting to link a named pipe on a striped, replicated volume. The cause for this crash is attempting to deref a NULL inode pointer in stripe_link_cbk(). The RCA for this bug uncovered a couple of problems: - AFR ignores the inode pointer it receives on failure (returning NULL). - stripe assumes the inode pointer is valid on failure. Either one of these changes addresses the crash, but this patch includes both changes. AFR is modified to pass along the inode pointer it receives (which could still be NULL). stripe is modified to not assume the inode pointer is valid on fop failure.

* 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.

* cluster/stripe: implement the coalesce stripe file formatBrian Foster2012-07-185-79/+409
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The coalesce file format for cluster/stripe condenses the striped files to a contiguous layout. The elimination of holes in striped files eliminates space wasted via local filesystem preallocation heuristics and significantly improves read performance. Coalesce mode is implemented with a new 'coalesce' xlator option, which is user-configurable and disabled by default. The format of newly created files is marked with a new 'stripe-coalesce' xattr. Cluster/stripe handles/preserves the format of files regardless of the current mode of operation (i.e., a volume can simultaneously consist of coalesced and non-coalesced files). Files without the stripe-coalesce attribute are assumed to have the traditional format to provide backward compatibility. extras/stripe-merge: support traditional and coalesce stripe formats Update the stripe-merge recovery tool to handle the traditional and coalesced file formats. The format of the file is detected automatically (and verified) via the stripe-coalesce attributes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit is based on Venky Shankar <vshankar@>'s original implementation. Let us first quote Venky's description, then we summarize changes to his work. ------ First version of failover/failback. Failback mechanism uses two exclusive modes: * blind-sync This mode works with xtime pairs (both master and slave) to identify candidated to sync the original master from the slave * wrapup-sync This mode is similar to the normal working of gsyncd except that orphaned entities in the gluster volume are not assigned xtimes. This prevents un-necessary transfer of data for such entities. Modes can be enabled via: gluster volume geo-replication M S config special_sync_mode blind gluster volume geo-replication M S config special_sync_mode wrapup To turn off the special modes (i.e. to revert to normal gsyncd behaviour) use: gluster volume geo-replication colon-d0 192.168.1.2::colon-d config \!special_sync_mode ------ Code has been refactored to meet following goals: - make checkpointing work with special sync modes - move out sync mode related conditionals from the crawl loop and make all decisions to be made at startup time - be intrusive to the crawl loop to smallest possible degree (we will have to change/revisit it for other reasons, and the complexity of that should not increase) So, xtime parsing/updating/evaluation that's specific to the certain special modes are represented as mixin classes; basic operation logic is in an abstract base class. On startup, special-sync-mode tunable is dynamically dispatched to the corresponding mixin and the actual master class is derived from the chosen mixin and the ABS.

* geo-rep / gsyncd: fix cleanup of temporary mountsCsaba Henk2012-06-101-17/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [This is a "forward port" of fafd5c17, http://review.gluster.com/2908] The "finally" clause that was meant to cleanup after the temp mount has not covered the case of getting signalled (eg. by monitor, upon worker timing out). So here we "outsource" the cleanup to an ephemeral child process. Child calls setsid(2) so it won't be bothered by internal process management. We use a pipe in between worker and the cleanup child; when child sees the worker end getting closed, it performs the cleanup. Worker end can get closed either because worker closes it (normal case), or because worker has terminated (faulty case) -- thus as bonus, we get a nice uniform handling with no need to differentiate between normal and faulty cases. The faulty case that was seen IRL -- ie., users of maintainance mounts hang in chdir(2) to mount point -- can be simulated for testing purposes by applying the following patch: diff --git a/xlators/mount/fuse/src/fuse-bridge.c b/xlators/mount/fuse/src/fuse-bridge.c index acd3c68..1ce5dc1 100644 --- a/xlators/mount/fuse/src/fuse-bridge.c +++ b/xlators/mount/fuse/src/fuse-bridge.c @@ -2918,7 +2918,7 @@ fuse_init (xlator_t *this, fuse_in_header_t *finh, void *msg) if (fini->minor < 9) *priv->msg0_len_p = sizeof(*finh) + FUSE_COMPAT_WRITE_IN_SIZE; #endif - ret = send_fuse_obj (this, finh, &fino); + ret = priv->client_pid_set ? 0 : send_fuse_obj (this, finh, &fino); if (ret == 0) gf_log ("glusterfs-fuse", GF_LOG_INFO, "FUSE inited with protocol versions:" Change-Id: I14bad56a60a7fa82d0104fa4b9a20f4e42a7186f BUG: 786291 Signed-off-by: Csaba Henk <csaba@redhat.com> Reviewed-on: http://review.gluster.com/3542 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Vijay Bellur <vijay@gluster.com>

* fuse, glusterfsd: mount logic fixesCsaba Henk2012-05-272-62/+21

This patch fixes these issues by a refactor that merges the approaches sported by commits 7d0397c2 fuse: allow requests during mount (needed for SELinux labels) c5d781e0 upon daemonizing, wait on mtab update to terminate in parent Original daemonized libfuse event flow is as follows: try: fd = open("/dev/fuse") mount("-oopts,fd=%s" % fd ...) mount(8) -f # manipulate mtab except: sp = socketpair() env _FUSE_COMMFD=sp fusermount -oopts fd = receive_fd(sp) where fusermount(1) does: fd = open("/dev/fuse") mount("-oopts,fd=%d" % fd ...) sp = atoi(getenv("_FUSE_COMMFD")) send_fd(sp, fd) daemonize( # in child fuse_loop(fd) ) # in parent exit() As of 013850c9 (instead of adopting FUSE's 47e61004¹), we went for async mtab manipulation, and as of c5d781e0, still wanted keep that in sync with termination of daemon parent, so we changed it to: try: fd = open("/dev/fuse") mount("-oopts,fd=%s" % fd ...) pid = fork( # in child mount(8) -f ) except: sp = socketpair() env _FUSE_COMMFD=sp fusermount -oopts fd = receive_fd(sp) daemonize( fuse_loop(fd) ) waitpid(pid) exit() (Note the new approch came only to direct [privileged] mount, so fusermount based mounting was already partially broken.) As of 7d0397c2, with the purpose of facilitating async mount, the event flow was practically reduced to: fd = open("/dev/fuse") fork( mount("-oopts,fd=%s" % fd ...) fork( mount(8) -n ) ) daemonize( fuse_loop(fd) ) exit() Thus fusermount based mounting become defunct; however, the dead code was still kept around. So, we should either drop it or fix it. Also, the mtab manipulator is forked into yet another child with no purpose, while syncing with it in daemon parent is broken. mount(2) is neither synced with parent. Now we are coming to the following scheme: fd = open("/dev/fuse") pid = fork( try: mount("-oopts,fd=%s" % fd ...) mount(8) -n except: env _FUSE_DEVFD=fd fusermount -oopts ) where fusermount(1) does: fd = getenv("_FUSE_DEVFD") mount("-oopts,fd=%s" % fd ...) daemonize( fuse_loop(fd) ) waitpid(pid) exit() Nb.: - We can't help losing compatibility with upstream fusermount, as it sends back the fd only when mount(2) is completed, thus defeating the async mount approach. The 'getenv("_FUSE_DEVFD")' mechanism is specfic to glusterfs' fusermount (at the moment -- sure we can talk about it with upstream) - fusermount opens /dev/fuse at same privilege level as of original process², so we can bravely go on with doing the open unconditionally in original process - Original mounting code actually tries to mount through fusermount _twice_: if first attempt fails, then, assuming subtype support is missing in kernel, it tries again subtype stripped. However, this is redundant, as fusermount internally also performs the subtype check³. Therefore we simplified the logic to have just a single fusermount call. - we revert the changes to mount.glusterfs as of 7d0397c2, as now there is no issue with glusterfs to work around in that scope ¹ http://fuse.git.sourceforge.net/git/gitweb.cgi?p=fuse/fuse;a=blobdiff;f=ChangeLog;h=47e61004;hb=4c3d9b19;hpb=e61b775a ² http://fuse.git.sourceforge.net/git/gitweb.cgi?p=fuse/fuse;a=blob;f=util/fusermount.c;h=b2e87d95#l1023 ³ http://fuse.git.sourceforge.net/git/gitweb.cgi?p=fuse/fuse;a=blob;f=util/fusermount.c;h=b2e87d95#l839 Change-Id: I0c4ab70e0c5ad7b27337228749b266bcd0ba941d BUG: 811217 Signed-off-by: Csaba Henk <csaba@redhat.com> Reviewed-on: http://review.gluster.com/3428 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Vijay Bellur <vijay@gluster.com>
