[NFS-Ganesha-Devel] Change in ...nfs-ganesha[next]: PROXY_V3: work around bindresvport threadsafety.

Solomon Boulos has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/502353 ) Change subject: PROXY_V3: work around bindresvport threadsafety. ...................................................................... PROXY_V3: work around bindresvport threadsafety. To get a privileged port, the V3 proxy's rpc code asks bindresvport_sa to hand us one. Modern versions of glibc (since 2.17) are thread-safe, but many existing implementations (including libntirpc) just use a local static variable for the "choose a port". The V4 proxy calls the related rresvport_af but is holding a lock, so it's at least single threaded amongst itself. The race here was causing the client port to sometimes be an unprivileged port, so knfsd was correctly returning a permission error.
