Bring in a hybrid of SunSoft's transport-independent RPC (TI-RPC) and associated changes that had to happen to make this possible as well as bugs fixed along the way. Bring in required TLI library routines to support this. Since we don't support TLI we've essentially copied what NetBSD has done, adding a thin layer to emulate direct the TLI calls into BSD socket calls. This is mostly from Sun's tirpc release that was made in 1994, however some fixes were backported from the 1999 release (supposedly only made available after this porting effort was underway). The submitter has agreed to continue on and bring us up to the 1999 release. Several key features are introduced with this update: Client calls are thread safe. (1999 code has server side thread safe) Updated, a more modern interface. Many userland updates were done to bring the code up to par with the recent RPC API. There is an update to the pthreads library, a function pthread_main_np() was added to emulate a function of Sun's threads library. While we're at it, bring in NetBSD's lockd, it's been far too long of a wait. New rpcbind(8) replaces portmap(8) (supporting communication over an authenticated Unix-domain socket, and by default only allowing set and unset requests over that channel). It's much more secure than the old portmapper. Umount(8), mountd(8), mount_nfs(8), nfsd(8) have also been upgraded to support TI-RPC and to support IPV6. Umount(8) is also fixed to unmount pathnames longer than 80 chars, which are currently truncated by the Kernel statfs structure.

char *addrmerge(struct netbuf *caller, char *serv_uaddr, char *clnt_uaddr,

When you have multiple addresses on the same network on different interfaces (such as when you are part of a carp pool), and you run rpcbind -h to restrict which interfaces have rpc services, rpcbind can none-the-less return addresses that aren't in the -h list. This patch enforces the rule that when you specify -h on the command line, then services returned from rpcbind must be to one of the addresses listed in -h, or be a loopback address (since localhost is implicit when running -h). The root cause of this is the assumption in addrmerge that there can be only one interface that matches a given network IP address. This turns out not to be the case. To retain historical behavior, I didn't try to fix the routine to prefer the address that the request came into, since I didn't know the side effects that might cause in the normal case. My quick analysis suggests that it wouldn't be a problem, but since this code is tricky I opted for the more conservative patch of only restricting the reply when -h is in effect. Hence, this change will have no effect when you are running rpcbind without -h. Reviewed by: alfred@ Sponsored by: iX Systems MFC after: 2 weeks
