rdma:vectored write fails for rdma.

2015-01-07T05:41:17+00:00

        Backport of http://review.gluster.org/9247

For rdma write with payload count greater than one
will fail due to insuffient memory to hold the
buffers in rpc transport layer. It was expecting
only one vector in payload, So it can only able
to decode the first iovec from payload, and the
rest will be discarded.

Thnaks to Raghavendra Gowdappa for fixing the
same.

snapview-server: register a callback with glusterd to get

2014-09-18T17:59:30+00:00

 notifications

* As of now snapview-server is polling (sending rpc requests to glusterd) to
  get the latest list of snapshots at some regular time intervals
  (non configurable). Instead of that register a callback with glusterd so that
  glusterd sends notifications to snapd whenever a snapshot is created/deleted
  and snapview-server can configure itself.

Do not call rpc_transport_unref() on NULL trans

2014-09-16T11:32:43+00:00

rpc_clnt_disable() sets rpc->conn->trans to NULL, hence we should not
call rpc_transport_unref() afterwards. I moved it before the
rpc_clnt_disable() call, but I am not sure it should be called at all,
perhaps it should just go away.

build: make GLUSTERD_WORKDIR rely on localstatedir

2014-09-03T18:01:45+00:00

Backport from master branch - http://review.gluster.org/#/c/8246/

- Break-way from '/var/lib/glusterd' hard-coded previously,
  instead rely on 'configure' value from 'localstatedir'
- Provide 's/lib/db' as default working directory for gluster
  management daemon for BSD and Darwin based installations
- loff_t is really off_t on Darwin
- fix-off the warnings generated by clang on FreeBSD/Darwin
- Now 'tests/*' use GLUSTERD_WORKDIR a common variable for all
  platforms.
- Define proper environment for running tests, define correct PATH
  and LD_LIBRARY_PATH when running tests, so that the desired version
  of glusterfs is used, regardless where it is installed.
  (Thanks to manu@netbsd.org for this additional work)

rpc: Do not reset @ping_started to 0 in ping callback

2014-07-09T13:57:20+00:00

This is to avoid indefinite recursion of the following kind, that could
lead to a stack overflow:

rpc_clnt_start_ping() -> rpc_clnt_ping() -> rpc_clnt_submit() ->
rpc_clnt_start_ping() -> rpc_clnt_ping() -> rpc_clnt_submit() ...
and so on,

since it is possible that before rpc_clnt_start_ping() is called a
second time by the thread executing this codepath, the response to
previous ping request could ALWAYS come by and cause epoll thread to
reset conn->ping_started to 0.

This patch also fixes the issue of excessive ping traffic, which was
due to the client sending one ping rpc for every fop in the worst case.

Also removed dead code in glusterd.

rpc/auth: allow SSL identity to be used for authorization

2014-07-02T09:47:05+00:00

Access to a volume is now controlled by the following options, based on
whether SSL is enabled or not.

 * server.ssl-allow: get identity from certificate, no password needed

 * auth.allow: get identity and matching password from command line

It is not possible to allow both simultaneously, since the connection
itself is either using SSL or it isn't.

gNFS: Fix multi-homed m/c issue in NFS subdir auth

2014-06-25T07:41:52+00:00

NFS subdir authentication doesn't correctly handle multi-homed
(host with multiple NIC having multiple IP addr) OR multi-protocol
(IPv4 and IPv6) network addresses.

When user/admin sets HOSTNAME in gluster CLI for NFS subdir auth,
mnt3_verify_auth() routine does not iterate over all the resolved
n/w addrs returned by getaddrinfo() n/w API. Instead, it just tests
with the one returned first.

1. Iterate over all the n/w addrs (linked list) returned by getaddrinfo().
2. Move the n/w mask calculation part to mnt3_export_fill_hostspec()
   instead of doing it in mnt3_verify_auth() i.e. calculating for each
   mount request. It does not change for MOUNT req.
3. Integrate "subnet support code rpc-auth.addr..allow"
   and "NFS subdir auth code" to remove code duplication.
