mount/fuse: Handle fd resolution failures

2014-09-12T09:17:42+00:00

        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

mount/fuse: adding a setxattr filter pass for geo-rep create.

Adding filter pass for setxattr when key is "glusterfs.gfid.newfile".
This was blocking creates at slave volume.

fuse: revalidate group id cache on uid/gid change detection

2013-11-21T21:11:18+00:00

- Remember the uid and gid of the pid at the time of caching
  the group id list.

- Next time when referring to the cache confirm that uid and gid
  of that pid has not changed since. If it has, treat it like
  a timeout/cache miss.

- Solves group id caching issue caused when Samba runs on gluster
  FUSE mount and changes the uid/gid on a per syscall basis.

fuse: auxiliary gfid mount support

2013-07-19T08:14:08+00:00

* files can be accessed directly through their gfid and not just
  through their paths. For eg., if the gfid of a file is
  f3142503-c75e-45b1-b92a-463cf4c01f99, that file can be accessed
  using /.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 /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.

Thanks to "Amar Tumballi"  and "Csaba Henk"
 for their inputs.
