quota/marker: set lk_owner when taking lock on parent in rename

2015-09-21T06:49:16+00:00

This is a backport of http://review.gluster.org/#/c/11561/

Before doing a rename operation marker takes inode lock on the file
parent,
here lk_owner is NULL and this can cause accounting problem with
multiple rename on the same directory

This patch fix the problem by setting lk_owner

fuse: add "resolve-gids" mount option to overcome 32-groups limit

2015-09-21T06:45:07+00:00

Add a --resolve-gids commandline option to the glusterfs binary. This
option gets set when executing "mount -t glusterfs -o resolve-gids ...".

This option is most useful in combination with the "acl" mount option.
POSIX ACL permission checking is done on the FUSE-client side to improve
performance (in addition to the checking on the bricks).

The fuse-bridge reads /proc/$PID/status by default, and this file
contains maximum 32 groups. Any local (client-side) permission checking
that requires more than the first 32 groups will fail.

By enabling the "resolve-gids" option, the fuse-bridge will call
getgrouplist() to retrieve all the groups from the user accessing the
mountpoint. This is comparable to how "nfs.server-aux-gids" works.

Note that when a user belongs to more than ~93 groups, the volume option
server.manage-gids needs to be enabled too. Without this option, the
RPC-layer will need to reduce the number of groups to make them fit in
the RPC-header.

nfs: make it possible to disable nfs.mount-rmtab

2015-08-18T13:19:48+00:00

When there are many NFS-clients doing very often mount/unmount actions,
the updating of the 'rmtab' can become a bottleneck and cause delays. In
these situations, the output of 'showmount' may be less important than
the responsiveness of the (un)mounting.

By setting 'nfs.mount-rmtab' to the value "/-", the cache file is not
updated anymore, and the entries are only kept in memory.

rdma: pre-register iobuf_pool with rdma devices.

2015-03-27T11:34:08+00:00

        Back port pf : http://review.gluster.org/9506

registring buffers with rdma device is a time consuming
operation. So performing registration in code path will
decrease the performance.
Using a pre registered memory will give a bettor performance,
ie, register iobuf_pool during rdma initialization. For
dynamically created arena, we can register with all the
device.

NetBSD portability fix: recover errno on runner error

2015-02-04T12:06:45+00:00

Some time ago we introduced F_CLOSEM to efficiently close unused
file descriptors when using a runner. But since it also close the
file descriptor used to send back errno to glusterd, it got unable
to detect an error on execve().

Fix this by backing out F_CLOSEM usage.
