* mount/fuse: Handle fd resolution failuresv3.5.3beta1Pranith Kumar K2014-10-014-187/+82
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Backport of http://review.gluster.org/8402 Problem: Even when the fd resolution failed, the fop is continuing on the new graph which may not have valid inode. This lead to NULL layout subvols in dht which lead to crash in fsync after graph migration. Fix: - Remove resolution error handling in FUSE_FOP as it was only added to handle fd migration failures. - check in fuse_resolve_done for fd resolution failures and fail the fop right away. - loc resolution failures are already handled in the corresponding fops. - Return errno from state->resolve.op_errno in resume functions. - Send error to fuse on frame allocation failures. - Removed unused variable state->resolved - Removed unused macro FUSE_FOP_COOKIE BUG: 1136835 Change-Id: I5074f7a9b177c54051ef37a4f73de7f8d1fcc5b7 Signed-off-by: Pranith Kumar K <pkarampu@redhat.com> Reviewed-on: http://review.gluster.org/8595 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Niels de Vos <ndevos@redhat.com>
* fuse: prevent READDIR(P) from writing to much data to /dev/fuseNiels de Vos2014-05-081-16/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In an environment with mixed architectures (32-bit servers, 64-bit client), it is possible that the on-wire Reply on a READDIR(P) procedure contains more direntries than the client can fit in the maximum size that the fuse-request indicated. A direntry is a dynamically sized structure, because the structure contains the name of the entry. The client sends a maximum size in the READDIR(P) Call to the server, and the server uses this size to limit the number of direntries to return. In case the server can pack more direntries in the requested maximum size (due to alignment differences between the architectures), it can happen that the client unpacks the list of direntries into a buffer that exceeds the maximum size that was given in the initial fuse-request. This change introduces a check for the maximum requested size of the fuse-response in fuse_readdir_cbk() and fuse_readdirp_cbk(). When the conversion from gluster-direntries to the fuse-direntry format takes place, the maximum size is checked, and the 'extra' direntries are discarded. The next readdir()/getdents() that is done, will fetch the just discarded direntries again. In addition to this bugfix, some extra logging in send_fuse_iov() and send_fuse_data() has been added to help diagnosing similar issues. This change combines two commits from master: > Commit: 20e317011af7c0f075819bf0648b225f6dc42350 > Change-Id: If2eecfcdf9c248f3820035601446d2c89ff9d1a1 > BUG: 1074023 > Signed-off-by: Niels de Vos <ndevos@redhat.com> > Reviewed-on: http://review.gluster.org/7278 > Tested-by: Gluster Build System <jenkins@build.gluster.com> > Reviewed-by: Xavier Hernandez <xhernandez@datalab.es> > Reviewed-by: Anand Avati <avati@redhat.com> > > Commit: 76ab97169f63da78c9e83daf040d7b09766497cf > Change-Id: Ic62d9d729a86a1a6a53ed1354fce153bac01d860 > BUG: 1074023 > Reported-by: Kaleb S.

* mount/fuse: cleanup old graphs.Raghavendra G2014-01-281-6/+24
| | | | | | | | | | | | | | | | | | | | | | | After a graph switch, a PARENT_DOWN event from fuse indicates protocol/client to shutdown all its sockets. However, this event will be sent only when the first fop is received from fuse mount after graph switch. Also, this event is sent only on previously active graph. So, if there are multiple graph switches when there is no activity on mountpoint, we'll be left with a list of graphs with their sockets still open. This patch fixes the issue by sending PARENT_DOWN to previously non-active graph when a new graph is available irrespective of whether there is an activity on mount-point.

| | | | | | | | | | | | | | | | | | | | | | | | Problem: Incorrect NFS ACL encoding causes "system.posix_acl_default" setxattr failure on bricks on XFS file system. XFS (potentially others?) doesn't understand when the 0x10 prefix is added to the ACL type field for default ACLs (which the Linux NFS client adds) which causes setfacl()->setxattr() to fail silently. NFS client adds NFS_ACL_DEFAULT(0x1000) for default ACL. FIX: Mask the prefix (added by NFS client) OFF, so the setfacl is not rejected when it hits the FS.

Update the header version number. 7.20 - Adds the FUSE_AUTO_INVAL_DATA init flag to enable attribute updates on reads and automatic cache invalidation on mtime changes. Behavior does not change unless the init flag is specified, no gluster changes required. Update header. 7.21 - Adds readdirplus support and updates the poll request to include events. Gluster already supports readdirplus and includes the relevant data structures. Poll is not supported, so no changes are required. Update the header with some missing READDIRPLUS_AUTO bits. 7.22 - Adds real asynchronous direct I/O support.

For eg., if the gfid of a file is f3142503-c75e-45b1-b92a-463cf4c01f99, that file can be accessed using <gluster-mount>/.gfid/f3142503-c75e-45b1-b92a-463cf4c01f99 .gfid is a virtual directory used to seperate out the namespace for accessing files through gfid. This way, we do not conflict with filenames which can be qualified as uuids. * A new file/directory/symlink can be created with a pre-specified gfid. A setxattr done on parent directory with fuse_auxgfid_newfile_args_t initialized with appropriate fields as value to key "glusterfs.gfid.newfile" results in the entry <parent>/bname whose gfid is set to args.gfid. The contents of the structure should be in network byte order. struct auxfuse_symlink_in { char linkpath[]; /* linkpath is a null terminated string */ } __attribute__ ((__packed__)); struct auxfuse_mknod_in { unsigned int mode; unsigned int rdev; unsigned int umask; } __attribute__ ((__packed__)); struct auxfuse_mkdir_in { unsigned int mode; unsigned int umask; } __attribute__ ((__packed__)); typedef struct { unsigned int uid; unsigned int gid; char gfid[UUID_CANONICAL_FORM_LEN + 1]; /* a null terminated gfid string * in canonical form. */ unsigned int st_mode; char bname[]; /* bname is a null terminated string */ union { struct auxfuse_mkdir_in mkdir; struct auxfuse_mknod_in mknod; struct auxfuse_symlink_in symlink; } __attribute__ ((__packed__)) args; } __attribute__ ((__packed__)) fuse_auxgfid_newfile_args_t; An initial consumer of this feature would be geo-replication to create files on slave mount with same gfids as that on master. It will also help gsyncd to access files directly through their gfids. gsyncd in its newer version will be consuming a changelog (of master) containing operations on gfids and sync corresponding files to slave. * Also, bring in support to heal gfids with a specific value. fuse-bridge sends across a gfid during a lookup, which storage translators assign to an inode (file/directory etc) if there is no gfid associated it. This patch brings in support to specify that gfid value from an application, instead of relying on random gfid generated by fuse-bridge. gfids can be healed through setxattr interface. setxattr should be done on parent directory. The key used is "glusterfs.gfid.heal" and the value should be the following structure whose contents should be in network byte order. typedef struct { char gfid[UUID_CANONICAL_FORM_LEN + 1]; /* a null terminated gfid * string in canonical form */ char bname[]; /* a null terminated basename */ } __attribute__((__packed__)) fuse_auxgfid_heal_args_t; This feature can be used for upgrading older geo-rep setups where gfids of files are different on master and slave to newer setups where they should be same. One can delete gfids on slave using setxattr -x and .glusterfs and issue stat on all the files with gfids from master.

* mount/fuse: unlink the inode on revalidate if entry not foundBrian Foster2013-07-181-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | If an inode/dentry is linked via a client and removed via a separate client, the inode/dentry mapping in the initial client remains. A lookup of the removed name on the initial client typically returns ENOENT once the associated caches expire. If the initial client has multiple dentries linked to the same inode, however, lookups on the non-removed dentry create windows of time where lookups on the stale/removed name return successfully. This occurs because the stale mapping resolves to the still valid inode and tricks md-cache into returning valid lookup data. To correct this situation, unlink the stale inode mapping on a failed (ENOENT) revalidation lookup (i.e., when fuse has resolved the inode but a lookup returns ENOENT). Note that with this change, the state still occurs until an md-cache window has expired, allowed a lookup to pass through to the server and given the fuse translator an opportunity to clean up.
