Subject: mount.nfs: support netids in nfs_options2pmap()
X-Git-Tag: nfs-utils-1-2-2-rc2~8
X-Git-Url: https://git.decadent.org.uk/gitweb/?a=commitdiff_plain;h=5ba18c11f31a135c6eeab67e820c271f87004793;p=nfs-utils.git

mount.nfs: support netids in nfs_options2pmap()

When parsing mount options in nfs_options2pmap(), treat the value of
proto= (and mountproto=) as a netid by looking it up in local
netconfig and protocol databases to convert it to a protocol number.
If TI-RPC is not available, the traditional behavior is preserved.

The meaning of the "udp" and "tcp" mount options is not affected by
this change.
