protocol: utilize the version 4 xdr

build: use libtirpc by default, even if ipv6 is not the default

2018-01-30T18:36:28+00:00

Another error snuck in with Change-Id I86f847dfd, or more
accurately I think, with Change-Id: Ic47065e9c2...

All libs, not just libgfrpc, need to be linked with libtirpc,
especially on systems that still have xdr functions in (g)libc
where you will get a mixture of calls to libtirpc functions
and glibc functions, with catas

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.

rpc/*: auth-header changes

2018-01-17T06:00:39+00:00

Introduce another authentication header which can now send more data.
This is useful because this data can be common for all the fops, and
we don't need to change all the signatures.

As part of this, made rpc-clnt.c little more modular to support multiple
authentication structures.

stack.h changes are placeholder for the ctime etc, can be moved later
based on need.

dict: add another type to handle backward compatibility

2018-01-17T03:53:37+00:00

This new type helps to avoid excessive logs. It should be
set only in case of
 * volume graph building (graph.y)
 * dict unserialize
   (happens once a dictionary is received on wire in old protocol)

All other dict set and get should have proper check and warning
logs if there is a mismatch.

locks: added inodelk/entrylk contention upcall notifications

2018-01-16T10:37:22+00:00

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.

rpc: use export map to minimize exported symbols in libgf{rpc,xdr}.so

2018-01-12T06:53:13+00:00

Without an export map (at link time) libgrpc and libgfxdr export over
150 and 450 symbols each, respectively. Many are not used by anything
else. (Unclear what the unused symbols are, some may be simple
sloppiness, e.g. not declaring functions static that should be. Others
may be intra-library calls that can't be static but aren't part of the
API, per se.)

By linking with an export map the number of exported symbols is
reduced to ~60 and ~250 respectively.

This parallels the similar change made to libglusterfs recently
and the older changes to the xlators to minimize the symbols that
are visible (exported) from the .so.

And I don't know, do we want to go all the way to symbol versions?
For these libs? And for libglusterfs?

dict: add more types for values

2018-01-05T09:35:07+00:00

Added 2 more types which are present in gluster codebase, mainly
IATT and UUID.
