rpcsvc: scale rpcsvc_request_handler threads

2018-03-20T12:17:40+00:00

Scale rpcsvc_request_handler threads to match the scaling of event
handler threads.

Please refer to https://bugzilla.redhat.com/show_bug.cgi?id=1467614#c51
for a discussion about why we need multi-threaded rpcsvc request
handlers.

build: address linkage issues

2018-03-06T13:43:53+00:00

We have the following undefined symbol error from protocol/server.so:

  glusterfs_mgmt_pmap_signout
  glusterfs_autoscale_threads

See https://review.gluster.org/19225 (bz#1532238)
and https://review.gluster.org/19657 (bz#1550895)

IMO this is a cleaner solution. I.e. moving the above two functions
to libgfrpc (.../rpc/rpc-lib/...)

I would also, for (foolish) consistency sake, like to see
glusterfs_mgmt_pmap_signin() moved from glusterfsd to libgfrpc as
well.

This works on f28/rawhide, with its new, more restrictive run-time
link semantics. The smoke and regression tests on earlier fedora and
centos will confirm that it works on those platforms too.

rpc: Adds rpcbind6 programs to libgfrpc symbols

2018-02-15T14:34:01+00:00

Building with --with-default-ipv6 causes shared
components of gluster calling the rpcbind6 functions
to fail. Adding the symbols in the list is all that is
necessary. Building without ipv6 keeps the same behavior.

No test cases as this is a build-specific fix.

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.
