* mount/fuse: Implement forget in cbks for fuse.Vijay Bellur2013-09-191-0/+8
| | | | | | | | | | | | | | | | | | | | | | With the introduction of inode_ctx_set in fuse as part of 2991503d014, forget cbk gets called for fuse xlator. Though nothing needs to be done inf forget_cbk, excessive log messages of the following kind are observed: [2013-09-16 06:09:50.758063] W [defaults.c:1331:default_forget] (-->/usr/local/lib/glusterfs/3git/xlator/mount/fuse.so(+0xa1f2) [0x7f51432781f2] (-->/usr/local/lib/libglusterfs.so.0(inode_unref+0x3c) [0x7f5144e5 816c] (-->/usr/local/lib/libglusterfs.so.0(+0x2d061) [0x7f5144e58061]))) 0-fuse: xlator does not implement forget_cbk This patch prevents such log messages from being seen.

* mount/fuse: save the basefd flags in the new fdRaghavendra Bhat2013-09-101-0/+1
| | | | | | | | | | | | | | Upon graph switch, the basefd's flags were not saved in the new fd created for the new graph upon which all the further requests for the open file would come. Thus posix was treating the fd as a read-only fd and was denying the write on the fds.

| | | | | | | | | | | | | | | | | | | | | | The internal mount API had no access to the generic mountflags used by mount(2). Thus the "ro" mount option that needs to be passed down to mount(2) as as a mountflag was incorrectly mangled into the fuse-specific mount parameter string (cf. http://review.gluster.com/655).

* fuse: create a new fd during fd-migration.Raghavendra G2012-10-021-102/+248
| | | | | | | | | | | | | | | | | | | | | | Migration of fd to new graph involves creation of a new fd to be used only for calls sent in that graph. Earlier approach of using same fd across all graphs, with the associated inode always guaranteed to be the one valid in currently active graph, had issues because of the broken immutability of the association of fd with an inode (for the life of fd). With this patch, there will be a basefd, which the kernel will be aware of. This basefd, contains a mapping of an fd which is valid in currently active graph.

| | | | | | | | | | | | | | | | | | | It is not possible to inode_link() with a NULL gfid. If a lookup (or any other "entry" op) returns a success but has a NULL gfid, then treat it as a failure even if op_ret was 0. Currently AFR does this when self-healing fails/aborts in certain situations (like entrylk acquisition failure, gfid mismatch etc.) returning a NULL gfid in struct iatt of lookup_cbk with op_ret = 0. Fixing this is an independent patch and fuse-bridge needs to be robust against such misformed replies in any case.

* glusterfs SEGV on Fedora 17 from UFO fallocate(2) callKaleb S. KEITHLEY2012-09-131-14/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | An upload of a file will cause the volume's glusterfs to SEGV when it fields a FUSE_FALLOCATE op. Swift inspects libc to determine if there is a symbol for fallocate(2) and if so will use it. And while the libc in RHEL 6 does have fallocate(2), the version of fuse in RHEL 6 does not support fallocate, and things are handled gracefully elsewhere (the kernel perhaps?) N.B. fallocate was added to version 7.19 of fuse. Fedora 17 and later (and maybe earlier too) has 7.19. RHEL 6 still has 7.13. Glusterfs uses the 7.13 version <linux/fuse.h> (in contrib/fuse-include/fuse_kernel.h) Thus on Fedora 17, with both fallocate(2) in libc and fallocate support in fuse, the fallocate invocation is dispatched to glusterfs, but the dispatch table (fuse_std_ops in xlators/mount/fuse/src/fuse-bridge.c) is too short for one thing; the fallocate opcode (43) indexes beyond the end of the table, and even when that doesn't directly cause a SEGV, the NULL pointer at that location does cause a SEGV when attempting to call the function through the pointer.

This would help us to continue with the _extra_ work (like healing gfid as of now) in fuse_lookup_resume.

* Fixes for gsyncd / geo-rep and FUSE listxattrVenky Shankar2012-07-241-4/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Shankar2012-07-191-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | | | | | | | | | | 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).

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).

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/3341 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Jeff Darcy <jdarcy@redhat.com> Reviewed-by: Anand Avati <avati@redhat.com>

The stat() seems to have been removed for performance reasons. Instead of removing d_type completely, dirent->d_type could have been used.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | was never attempted. Since fd is always associated with an inode, we can create an fd only after resolver resolves an inode. So, there is a possibility that graph-switch can happen after resolver kicks in, but before it can complete, thereby resulting in the newly created fd not migrated to new graph. So, instead of migrating fds only during graph-switch, we give a second chance during fd-resolution. As an example, consider following sequence of events during a create call: 1. create wants to resolve parent inode, hence it starts resolution for parent 2. graph-switch happens (it can happen since fuse-request reader thread returns after winding lookup calls) 3. fd-migration of all the fds which are currently in fdtable is attempted (Note that the fd corresponding to current create call is not yet created and added to fd-table, hence it will not be migrated as part of graph switch) 4. resolution of parent triggered as part of create, completes 5. fd is created in fuse_create_resume and this fd is not migrated to new graph 6. Any future fops on this fd will fail with EBADF errors (create call itself will succeed) Change-Id: Iae06ecfaca24eaacb2e166ffefbbbb57446332ba BUG: 804592 Signed-off-by: Raghavendra G <raghavendra@gluster.com> Reviewed-on: http://review.gluster.com/3181 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Anand Avati <avati@redhat.com>
