protocol : fix auth-allow regression
One of the brick multiplexing patches (commit 1a95fc3) had some changes in gf_auth () & server_setvolume () functions which caused auth-allow feature to be broken. mount doesn't succeed even if it's part of the auth-allow list. This fix does the following: 1. Reintroduce the peer-info data back in gf_auth () so that fnmatch has valid input and it can decide on the result. 2. config-params dict should capture key values pairs for all the bricks in case brick multiplexing is on. In case brick multiplexing isn't enabled, then config-params should carry attributes from protocol/server such that all rpc auth related attributes stay in tact in the dictionary. >Reviewed-on: https://review.gluster.org/16920 >Tested-by: Jeff Darcy <jeff@pl.atyp.us> >Smoke: Gluster Build System <jenkins@build.gluster.org> >NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> >CentOS-regression: Gluster Build System <jenkins@build.gluster.org> >Reviewed-by: Jeff Darcy <jeff@pl.atyp.us> >Reviewed-by: MOHIT AGRAWAL <moagrawa@redhat.com> >(cherry picked from commit 0bd58241143e91b683a3e5c4335aabf9eed537fe) Change-Id: I007c4c6d78620a896b8858a29459a77de8b52412 BUG: 1429117 Signed-off-by: Atin Mukherjee <amukherj@redhat.com> Reviewed-on: https://review.gluster.org/16967 Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Shyamsundar Ranganathan <srangana@redhat.com>
