Makefiles to GNUmakefiles so that non-GNU make(1) will error out.  This

Iterate on the DNS forwarding docs
 2016-02-02 15:14:37 -08:00
Sean Chittenden 7db70cfcb6 Iterate on the DNS forwarding docs 
Specifically:

* add Dnsmasq examples for reverse DNS for most of the RFC1918, 5735, and 6598 netblocks.
* Highlight some example options for dnsmasq that are probably of interest.
* Add a small section on reverse DNS testing
* Break out BINDs troubleshooting with Dnsmasq's troubleshooting

Not an exhaustive sweep, but should be helpful when introducing consul to new environments.

Sean Chittenden c7e58734ed Continually rebalance client connections 
Introduce a low-level background connection expiration mechanism wherein connections will be recycled periodically based on the size and health of the cluster.

For the vast majority of consul users, this will mean an average connection age of 150s.  For 10K node clusters it will take ~3min for clusters to rebalance their connections.  In the pathological case for a 100K cluster where 99K clients are in the minority talking to 1x server it will take ~26min to rebalance all connections.

It's possibe for clients recovering from a parititon to become fixated on a single server until the server or agent is restarted.  This is of particular interest to long-running environments with stable agents, where `allow_stale` is true, and partitions occur periodically.

Sean Chittenden c4f7b4a13e Rename clientRPCCache to clientRPCConnMaxIdle, change value 
Increase the max idle time for agents talking to servers from 30s to 127s in order to allow for the reuse of connections that are being initiated by cron.

127s was chosen as the first prime above 120s (arbitrarily chose to use a prime) with the intent of reusing connections who are used by once-a-minute cron(8) jobs *and* who use a 60s jitter window (e.g. in vixie cron job execution can drift by up to 59s per job, or 119s for a once-a-minute cron job).

Sean Chittenden b391b075bd Reuse the results from gettimeofday(2)...

Sean Chittenden 4382c1f7aa Always seed math/rand on consul startup 
Required for jitter calcs.  This could be done in consul/agent, but this makes it clear it is done only once process-wide.
