rpc: define client port range
Problem: when bind-insecure is 'off', all the clients bind to secure ports, if incase all the secure ports exhaust the client will no more bind to secure ports and tries gets a random port which is obviously insecure. we have seen the client obtaining a port number in the range 49152-65535 which are actually reserved as part of glusterd's pmap_registry for bricks, hence this will lead to port clashes between client and brick processes. Solution: If we can define different port ranges for clients incase where secure ports exhaust, we can avoid the maximum port clashes with in gluster processes. Still we are prone to have clashes with other non-gluster processes, but the chances being very low, but that's a different story on its own, which will be handled in upcoming patches. > Change-Id: Ib5ce05991aa1290ccb17f6f04ffd65caf411feaf > BUG: 1322805 > Signed-off-by: Prasanna Kumar Kalever <> > Reviewed-on: > Smoke: Gluster Build System <> > NetBSD-regression: NetBSD Build System <> > CentOS-regression: Gluster Build System <> > Reviewed-by: Atin Mukherjee <> > Reviewed-by: Raghavendra G <> > Signed-off-by: Prasanna Kumar Kalever <> Change-Id: I712676d3e79145d78a17f2c361525e6ef82a4732 BUG: 1323564 Signed-off-by: Prasanna Kumar Kalever <> Reviewed-on: Tested-by: Prasanna Kumar Kalever <> Smoke: Gluster Build System <> CentOS-regression: Gluster Build System <> NetBSD-regression: NetBSD Build System <> Reviewed-by: Raghavendra G <>
