rpc: Maintain separate xlator pointer in 'rpcsvc_state'

2015-05-05T13:29:20+00:00

The structure 'rpcsvc_state', which maintains rpc server
state had no separate pointer to track the translator.
It was using the mydata pointer itself. So callers were
forced to send xlator pointer as mydata which is opaque
(void pointer) by function prototype.

'rpcsvc_register_init' is setting svc->mydata with xlator
pointer. 'rpcsvc_register_notify' is overwriting svc->mydata
with mydata pointer. And rpc interprets svc->mydata as
xlator pointer internally. If someone passes non xlator
structure pointer to rpcsvc_register_notify as libgfchangelog
currently does, it might corrupt mydata. So interpreting opaque
mydata as xlator pointer is incorrect as it is caller's choice
to send mydata as any type of data to 'rpcsvc_register_notify'.

Maintaining two different pointers in 'rpcsvc_state' for xlator
and mydata solves the issue.

rpc: Introduce attribute throttle for rpcsvc_t

2015-05-03T18:04:33+00:00

This attribute will be used to set/unset throttling for
a rpcsvc_t program subsequently.

Following APIs have been added to get/set throttle.

int
rpcsvc_set_throttle (rpcsvc_t svc, gf_boolean_t value);

gf_boolean_t
rpcsvc_get_throttle (rpcsvc_t svc);

rpc/server: add anonuid and anongid options for root-squash

2013-12-31T03:49:43+00:00

Introduce new options to modify the behaviour of server.root-squash.
With server.anonuid and server.anongid the uid/gid can be specified and
the root user (uid=0 and gid=0) will be mapped to the given uid/gid
instead of nfsnobody (uid=65534 and gid=65534).

Many thanks to Vikhyat Umrao for writing the majority of the test-case!

gNFS: RFE for NFS connection behavior

2013-11-15T00:07:02+00:00

Implement reconfigure() for NFS xlator so that volume set/reset wont
restart the NFS server process. But few options can not be reconfigured
dynamically e.g. nfs.mem-factor, nfs.port etc which needs NFS to be
restarted.

Implement a limit on the total number of outstanding RPC requests
from a given cient. Once the limit is reached the client socket
is removed from POLL-IN event polling.

rpc: duplicate request cache for nfs

2013-06-21T17:33:49+00:00

Duplicate request cache provides a mechanism for detecting
duplicate rpc requests from clients. DRC caches replies
and on duplicate requests, sends the cached reply instead of
re-processing the request.

rpc: bring in root-squashing behavior in rpc

2013-02-17T20:01:55+00:00

* requests coming in as root are converted to nfsnobody

* with open-behind some acl checks wont happen and nfsnobody
  can read the file "whose owner is root and other users do not
  have permission to read the file". This is becasue open-behind
  does not send the open to the brick and sends success to the
  application, thus the acl related tests on the file wont happen
  which would have prevented the file from being opened.
