CCS fix: magmamsg doesn't work if route is incorrect
Last modified: 2009-04-16 16:34:34 EDT
+++ This bug was initially created as a clone of Bug #298831 +++
Description of problem:
If multiple IP addresses are bound to the same interface on the same subnet as
the primary cluster communications path, an incorrect routing configuration will
cause magmamsg (and therefore, other applications like rgmanager and ccsd) to
not function correctly.
If the cluster's hostname resolves to 192.168.78.1 - but the kernel routes
packets via the 192.168.78.0/24 subnet out via .10, the other members of the
cluster will deny the connection because .10 is does not match a cluster
member's IP address.
There are two solutions: DNS aliasing and this fix, which requires minor changes
to applications which use magmamsg.
Version-Release number of selected component (if applicable): 1.0.7-1
How reproducible: 100%
Steps to Reproduce: As described

Magma patch - applications should call msg_set_nodeid() prior to msg_open if
they use 'members_only' when doing msg_accept
