glusterd: populate brickinfo->real_path conditionally

2016-04-11T18:39:16+00:00

glusterd_brickinfo_new_from_brick () is called from multiple places and one of
them is glusterd_brick_rpc_notify where its very well possible that an
underlying brick's file system has crashed and a disconnect event has been
received. In this case glusterd tries to build the brickinfo from the brickid in
the RPC request, however the same fails as glusterd_brickinfo_new_from_brick ()
fails from realpath.

Fix is to skip populating real_path if its a disconnect event.

This allows GlusterD to send updates to all other nodes when attaching
new addresses using multi-net peer probe.

glusterd/rpc : Discard duplicate Disconnect events

2016-03-22T19:24:53+00:00

If a peer rpc disconnect event has been already processed, skip the furthers as
processing them are overheads and sometimes may lead to a crash like due to a
double free

As of now volume get was not looking for all the global options maintained in
option dictionary in glusterd_conf_t. This patch includes the same.

glusterd:upon re-peer probe glusterd should not return response to CLI two times

2016-03-08T09:10:27+00:00

If a node N1 and node N2 is part of the cluster and a node N2 try to reprobe
node N1 when N1 is disconnected by any means (for eg: either server is down
or glusterd is not running or there is a network outage, or firewall is
blocking port number 24007 on which glusterd listen, etc.), then glusterd
trying to send back two responses to CLI resulting into a double free and
a glusterd crash.

With this fix glusterd  will send response to cli only once and prevent
glusterd crash.

Note: glusterd was crashing only when user has done first peer probe with
hostname and re-probe with ip-address or vice-versa.

glusterd: reject peer probe from a reinstalled node

2016-03-04T12:10:22+00:00

In a cluster if a node (say N1) goes through a OS reinstallation then probing
some other node in the cluster from N1 doesn't fail as in
gd_validate_mgmt_hndsk_req () uuid & hostname checks are done separately but
there should be one more check where both the conditions should meet.

Steps to create the problem
- N1 probes N2
- bring down glusterd instance on N2
- remove /var/lib/glusterd/* from N2
- restart glusterd instance on N2
- execute gluster peer probe N1 from N2

Validations in gd_validate_mgmt_hndsk_req () has been improved to handle this
special case

glusterd: display user.* options in volume get

2016-02-28T04:39:08+00:00

As of now volume get framework doesn't consider user.* xattrs to be displayed.
This patch is to include them in volume get output. Please note these options will be
only shown for a given volume name, 'all' as a volume name wouldn't consider them displaying.
