protocol: Add framework to send transaction id with recall

2016-06-10T11:03:54+00:00

Backport of: http://review.gluster.org/#/c/14647/

Issue:
The upcall(cache invalidation/recall) event is sent from the bricks
to clients. In AFR/EC setup, it can so happen that all the bricks
will send the upcall for the same event, and if AFR/EC doesn't filter
out these duplicate notifications, the logic above cluster xlators
can fail.

Solution:
Use transaction id to filter out duplicate notifications.

This patch adds framework for duplicate notifications.
AFR/EC can build up on this patch for deduping the notifications

Upcall: Send stat as part of cache_invalidation notifications

2015-05-05T13:57:43+00:00

Have added support to send attributes of both entries and
its parent (include oldparent in case of RENAME fop) in the
same notification request to avoid multiple rpc requests.

Also, made changes in gfapi to send parent object and its
attributes changed in a single upcall event.

Upcall: Replaced opaque gfid with string in rpc cbk args

2015-04-30T12:11:31+00:00

For GF_CBK_CACHE_INVALIDATION, have changed the type of gfid
to be string (cannonical form) instead of opaque byte format
to ensure correctness across platforms supporting different
endianness.

Upcall: Process each of the upcall events separately

2015-04-30T11:51:46+00:00

As suggested during the code-review of Bug1200262, have modified
GF_CBK_UPCALL to be exlusively GF_CBK_CACHE_INVALIDATION.
Thus, for any new upcall event, a new CBK procedure will be added.

Also made changes to store upcall data separately based on the
upcall event type received.

gfapi: APIs to store and process upcall notifications received

2015-03-17T21:01:21+00:00

In case of any upcall cbk events received by the protocol/client,
gfapi will be notified which queues them up in a list ().

Applicatons are responsible to provide APIs to process & notify them in case
of any such upcall events queued.

Added a new API which will be used by Ganesha to repeatedly poll for any
such upcall event notified ().

A new test-file has been added to test the cache_invalidation upcall events.

Upcall: New xlator to store various states and send cbk events

2015-03-17T12:08:07+00:00

Framework on the server-side, to handle certain state of the files
accessed and send notifications to the clients connected.

A generic and extensible framework, used to maintain states in
the glusterfsd process for each of the files accessed
(including the clients info doing the fops) and send
notifications to the respective glusterfs clients incase of
any change in that state.

This patch handles "Inode Update/Invalidation" upcall event.

acl: enable handling of FMODE_EXEC flag

2012-07-28T04:39:08+00:00

on linux systems, with open(), we can get below flag as per
'linux/fs.h'.

/* File is opened for execution with sys_execve / sys_uselib */

Instead of adding '#include , its better to copy this
absolute number into other variable because then we have to deal
with declaring fmode_t etc etc..

With the fix, we can handle the file with '0711' permissions in
the same way as backend linux filesystems.

while doing the same effort, also enabled sending maximum of 500 aux gid
