options table.

libgfapi: Add new api for supporting mandatory-locks

2018-01-22T09:54:02+00:00

The current API for byte-range locks [glfs_posix_lock()] doesn't
allow applications to specify whether it is advisory or mandatory
type locks. This particular change is to introduce an extended
byte-range lock API with an additional argument for including
the byte-range lock mode to be one among advisory(default) or
mandatory. Patch also includes a gfapi test case which make use
of this new api to acquire mandatory locks.

md-cache: Implement dynamic configuration of xattr list for caching

2018-01-22T04:10:52+00:00

Currently, the list of xattrs that md-cache can cache is hard coded
in the md-cache.c file, this necessiates code change and rebuild
everytime a new xattr needs to be added to md-cache xattr cache
list.

With this patch, the user will be able to configure a comma
seperated list of xattrs to be cached by md-cache

protocol: make on-wire-change of protocol using new XDR definition.

2018-01-19T17:18:39+00:00

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.

afr: add quorum checks in post-op

2018-01-19T08:10:45+00:00

afr relies on pending changelog xattrs to identify source and sinks and the
setting of these xattrs happen in post-op. So if post-op fails, we need to
unwind the write txn with a failure.
