Subject: ctdb-tests: Add an event script unit test for updateip
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a98ffb96efc4a9ea2110c654860a4ba3896ab3d5;p=thirdparty%2Fsamba.git

ctdb-tests: Add an event script unit test for updateip

This illustrates the current failure where an unassigned public IP
address causes updateip to fail.

After commit 0536d7a98b832fc00d26b09c26bf14fb63dbf5fb (which improves
IP address state checking), this will almost certainly not occur on
platforms with getifaddrs(3) (e.g. Linux).  This means it is only
likely to occur in 4.21 when net.ipv4.ip_nonlocal_bind=1.
