Description Jonathan Earl Brassow 2004-10-14 19:15:58 UTC

Description of problem:
Please allow cman to send messages to self.

If my nodeid is 3, I would like to be able to send a message to myself (nodeid 
3):

saddr.scl_nodeid = my_id

sock_sendmsg(...)

Version-Release number of selected component (if applicable):
CVS

How reproducible:
always


Additional info:

Without this ability, the node providing a service will not be able to run that 
service.

In the cluster mirror, a server for the log is designated.  That machine is also a 
client and must be able to comunicate with the server thread.

This should work now. Note that if you want to include yourself in a
broadcast message then MSG_BCASTSELF should be added to the flags.

Comment 2 Jonathan Earl Brassow 2004-10-18 20:26:50 UTC

Yes, a machine can now send to itself.

However, after doing a sock_recvmsg, the scl_port # should be set to
the machine the packet was received from.  Instead, it is the machine
doing the receiving who's port is reported.

OK try that.

All good now.

Updating version to the right level in the defects.  Sorry for the storm.
