New Revision: 346463
URL: https://svnweb.freebsd.org/changeset/base/346463
Log:
MFC: r345992, r346087
Add INET6 support for the upcalls to the nfsuserd daemon.
The kernel code uses UDP to do upcalls to the nfsuserd(8) daemon to get
updates to the username<->uid and groupname<->gid mappings.
A change to AF_LOCAL last year had to be reverted, since it could result
in vnode locking issues on the AF_LOCAL socket.
This patch adds INET6 support and the required #ifdef INET and INET6
to the code.
