Summary of Changes:
while adding a primary address to the domR interface, previous primaray addresses(ip) are removed and added as with 32-bit netmask.
This is to avoid two same ip's with different netmask attached to the interface.
Because currently the lock in the script is retried every 1 second, and it's a
quite a long time that it's possible for some other active script can be
executed and retain the lock again. So it's possible that the first one request
the lock is always being preemptted by others, then finally got timeout.
To fix this issue, the retry interval is reduced to 0.1 seconds, which would
provide more retry times. And each process want to get the lock would create a
file named lockname-PID.lock, and only the first one(judged by timestamp) would
get the lock. The remaining ones would retry every 0.1 seconds to see if it can
get the lock.
Also timeout time is extended to 30 seconds.
And add testcase for it.
status 11772: resolved fixed
Added New value "link-local" to global config network.loadbalancer.haproxy.stats.visibility . With this change it can take new parameter "link-local" value apart from the existing 3 values global,guest-network,disabled.
global - stats visible from public network
guest-network - stats visible only to guestnetwork.
link-local - stats visible only to link local network
disabled - stats disabled.
This message may show during redundant router start up:
FAULT (Restarting DNS forwarder and DHCP server: dnsmasq failed!)
This caused by edithost.sh is racy with keepalived process. They both want to
restart dnsmasq.
Even in normal condition, it's very hard to reproduce this bug. Add file lock
for edithost.sh should solve it.
The issue happened quite rare, but indeed can show.
And when the issue happen, the status of redundant router would be "Status:
FAULT".
It's due to ipassoc.sh wasn't executed before the system bring eth2 up and go to
master mode, then eth2 wasn't configured correctly. Then "ip route add default
xx" can't complete.
This commit should fixes the issue.
