glusterd: Disable ping-timer between glusterd and brick process

2014-05-20T02:03:55+00:00

When there are too many IO happening, brick process epoll thread
will be busy and fails to respond to the glusterd pick packet within
30sec.
Also epoll thread can be blocked by a big-lock.

Solution is to disable ping-timer by default and only enable where ever
required

Later when the epoll thread model changed and made lighter,
we need to revert back this change. http://review.gluster.com/3842 is
one such approach.

rpc: implement server.manage-gids for group resolving on the bricks

2014-05-09T19:22:39+00:00

The new volume option 'server.manage-gids' can be enabled in
environments where a user belongs to more than the current absolute
maximum of 93 groups. This option triggers the following behavior:

1. The AUTH_GLUSTERFS structure sent by GlusterFS clients (fuse, nfs or
   libgfapi) will contain only one (1) auxiliary group, instead of
   a full list. This reduces network usage and prevents problems in
   encoding the AUTH_GLUSTERFS structure which should fit in 400 bytes.
2. The single group in the RPC Calls received by the server is replaced
   by resolving the groups server-side. Permission checks and similar in
   lower xlators are applied against the full list of groups where the
   user belongs to, and not the single auxiliary group that the client
   sent.

glusterd: Ping timer implmentation

2014-04-29T21:23:51+00:00

This patch refactors the existing client ping timer implementation, and makes
use of the common code for implementing both client ping timer and the
glusterd ping timer.

A new gluster rpc program for ping is introduced. The ping timer is only
started for peers that have this new program. The deafult glusterd ping
timeout is 30 seconds. It is configurable by setting the option
'ping-timeout' in glusterd.vol .

Also, this patch introduces changes in the glusterd-handshake path. The client
programs for a peer are now set in the callback of dump_versions, for both
the older handshake and the newer op-version handshake. This is the only place
in the handshake process where we know what programs a peer supports.

rpc: transport may be destroyed while rpc isn't

2014-03-06T05:26:59+00:00

rpc_clnt object is destroyed after the corresponding transport object is
destroyed. But rpc_clnt_reconnect, a timer driven function, refers to
the transport object beyond its 'life'. Instead, using the embedded
connection object prevents use after free problem wrt transport object.

Also, access transport object under conn->lock.

protocol: pass the size of the data in the WRITE on-wire FOP

2014-01-24T09:26:50+00:00

Capturing GlusterFS traffic with tcpdump and displaying it in Wireshark
shows that the size of all WRITEs are 0 bytes. It seems that the
attribute is not used, and the size is calculated an other way.

Even if the size attribute is not used (yet), it should be set correctly
to prevent confusing while debugging network traffic with Wireshark or
other tools.

Note that the on-wire format is not being changed with this patch. The
size is already part of the structure that is exchanged between the
client and server.
