Do not hardcode umount(8) path, emulate lazy umount

2014-10-03T15:01:29+00:00

1) Use a system-dependent macro for umount(8) location instead of
relying on $PATH  to find it, for security and portability sake.

2) Introduce gf_umount_lazy() to replace umount -l (-l for lazy) invocations,
which is only supported on Linux; On Linux behavior in unchanged. On other
systems, we fork an external process (umountd) that will take care of
periodically attempt to unmount, and optionally rmdir.

glusterd/quota: Heal pgfid xattr on existing data when the quota is enable

2014-09-30T16:42:40+00:00

This is a backport of http://review.gluster.org/#/c/8878/

The pgfid extended attributes are used to construct the ancestry path
(from the file to the volume root) for nameless lookups on files.
As NFS relies on nameless lookups heavily, quota enforcement through NFS
would be inconsistent if quota were to be enabled on a volume with
existing data.

Solution is to heal the pgfid extended attributes as a part of lookup
perfomed by quota-crawl process. In a posix lookup check for pgfid xattr
and if it is missing set the xattr.

Do not hardcode setfattr(1) path

Turn setfattr(1) absolute path into an OS-dependant macro. Let compiler
option override it to fit custom installation if needed.

gluster: Fix the recursive goto outs in the source code.

2014-09-08T06:35:36+00:00

Added a script check_goto.pl, that when run from
the source code root, will scan all .c files to match
the following pattern:

label:
        if (condition)
            goto label;

On finding such a pattern the script will print the file name
and the line number. There are certain cases where the above
recursive pattern is intended. Hence adding those labels to
ignore-labels. Thanks Vijaikumar Mallikarjuna for the perl
script.

Also fixed all such existing errors

Always check for ENODATA with ENOATTR

2014-09-08T06:23:42+00:00

Linux defines ENODATA and ENOATTR with the same value, which means that
code can miss on on the two without breaking.

FreeBSD does not have ENODATA and GlusterFS defines it as ENOATTR just
like Linux does.

On NetBSD, ENODATA != ENOATTR, hence we need to check for both values
to get portable behavior.

glusterd: Use blocking quotad start only on quota enable

2014-06-17T02:36:18+00:00

Having quotad always being using the blocking runner variant is
problematic. In some cases where quotad was started from the epoll
thread, it lead to a deadlock which lead to glusterd becoming
unresponsive.

This patch makes the default quotad_start function use the non-blocking
runner_nowait variant. The blocking start is used only when quotad is
started on quota enable command.

mgmt/gluster: Use fsync instead of O_SYNC

2014-05-05T20:52:51+00:00

Glusterd uses O_SYNC to write to temp file then performs renames
to the actual file and performs fsync on parent directory. Until
this rename happens syncing writes to the file can be deferred.
In this patch O_SYNC open of temp file is removed and fsync of the
fd before rename is done.
