* protocol: make on-wire-change of protocol using new XDR definition.Amar Tumballi2018-01-191-4/+299
| | | | | | | | | | | | | | | | | | | | | | With this patchset, some major things are changed in XDR, mainly: * Naming: Instead of gfs3/gfs4 settle for gfx_ for xdr structures * add iattx as a separate structure, and add conversion methods * the *_rsp structure is now changed, and is also reduced in number (ie, no need for different strucutes if it is similar to other response). * use proper XDR methods for sending dict on wire. Also, with the change of xdr structure, there are changes needed outside of xlator protocol layer to handle these properly. Mainly because the abstraction was broken to support 0-copy RDMA with payload for write and read FOP. This made transport layer know about the xdr payload, hence with the change of xdr payload structure, transport layer needed to know about the change.

* locks: added inodelk/entrylk contention upcall notificationsXavier Hernandez2018-01-161-0/+156
| | | | | | | | | | | | | | The locks xlator now is able to send a contention notification to the current owner of the lock. This is only a notification that can be used to improve performance of some client side operations that might benefit from extended duration of lock ownership. Nothing is done if the lock owner decides to ignore the message and to not release the lock. For forced release of acquired resources, leases must be used.

* dict: support better on-wire transferAmar Tumballi2017-12-271-0/+4
| | | | | | | | | | | | | | | This patch brings data type awareness to dictionary, and also makes sure valid data is properly sent to the other side of the wire using XDR. Next step is to allow people to add more data types (for example, Bool, UUID, iatt etc), and then make it part of every fop signature in wire.

* dht/md-cache: Filter invalidate if the file is made a linkto filePoornima G2016-12-021-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | Upcall as a part of setattr, sends an invalidation and the invalidation carries the resulting stat value. When a file is converted to linkto files, even then an invalidation is set and as a result the mountpoint shows the sticky bit in the stat of the file. eg: ---------T. 945 root root 0 Nov 8 10:14 hardlink.999 Fix: When dht recieves a notification of sticky bit change, it updates the flag, to indicate md-cache to send the subsequent lookup.

* protocol: Add framework to send transaction id with recallPoornima G2016-06-101-7/+23
| | | | | | | | | | | | | | | | | | | | | | | | | 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 Change-Id: I66b08e63b8799bc5932f2b2545376138a5701168 BUG: 1319992 Signed-off-by: Poornima G <pgurusid@redhat.com> Reviewed-on: http://review.gluster.org/14647 Smoke: Gluster Build System <jenkins@build.gluster.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Raghavendra Talur <rtalur@redhat.com> Reviewed-by: Raghavendra G <rgowdapp@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | In case of any upcall cbk events received by the protocol/client, gfapi will be notified which queues them up in a list (<gfapi_cbk_upcall>). 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 (<glfs_h_poll_upcall>). A new test-file has been added to test the cache_invalidation upcall events.

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