mount/fuse: readdir() should return 32-bit inodes when 'enable-ino32' is used

2012-09-18T13:54:59+00:00

The glusterfs mount option 'enable-ino32' does not change the behaviour
of readdir(). fuse_readdir_cbk() uses entry->d_ino directly, and this
was missed in commit c13823bd16b26bc471d3efb15f63b76fbfdf0309.

By adding the function gf_fuse_fill_dirent(), the fuse_dirent structure
is filled in a similar way as the fuse_attr structure. This helper uses
the same function to squash the 64-bit inode in a 32-bit attribute.

mount/fuse: add mount-option "enable-ino32" for the native client

2012-09-07T01:32:26+00:00

By default the GlusterFS-native client uses 64-bit inodes. Some 32-bit
applications can not handle these correctly. Introduce a client-side
mount option "enable-ino32" which causes the FUSE-client to squash the
64-bit inodes into a 32-bit value.

fuse: have setxattr on geo-rep related xattrs take effect

2012-08-19T16:30:52+00:00

In http://review.gluster.com/3687 setxattr was made to a noop for
geo-rep special clients, with the exception of some special ones,
relevant to geo-rep. These exceptions were all in trusted namespace.

That's no good, because with a mountbroker (unprivileged) setup,
the relevant attributes are in system namespace. So here we
just let setxattr through for any geo-rep related xattr, regardless
of namespace.

FUSE: ignore setxattr for some keys from gsyncd aux mount

2012-07-19T09:23:57+00:00

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.

libglusterfs,mount/fuse: implement gidcache mechanism in fuse-bridge

2012-07-17T15:11:48+00:00

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).
