core: run many bricks within one glusterfsd process

2017-01-31T00:13:58+00:00

This patch adds support for multiple brick translator stacks running
in a single brick server process.  This reduces our per-brick memory usage by
approximately 3x, and our appetite for TCP ports even more.  It also creates
potential to avoid process/thread thrashing, and to improve QoS by scheduling
more carefully across the bricks, but realizing that potential will require
further work.

Multiplexing is controlled by the "cluster.brick-multiplex" global option.  By
default it's off, and bricks are started in separate processes as before.  If
multiplexing is enabled, then *compatible* bricks (mostly those with the same
transport options) will be started in the same process.

protocol/server: No root-squash checks for self-heal pid

2014-12-04T19:34:09+00:00

Problem:
Self-heal pid used to be -1 which was colliding with gsyncd. Gsyncd
was not checked for root-squash authentication. Recently self-heal
pid changed to -6, but root-squash authentication is not disabled
for this.

Fix:
disable root-squash authentication for self-heal
