I wonder if an inode reference should be stored with the pathname
to allow a validity check?

Specifically, if two threads were doing concurrent lookups and the existing
gateway was marked down, the the first thread would drop a reference on the
gateway route and then unlock the "root" route while it tried to allocate
a new route. The second thread could then also drop a reference on the
same gateway route resulting in a reference underflow. Fix this by
clearing the gateway route pointer after dropping the reference count but
before dropping the lock. Secondly, in this same case, the second thread
would overwrite the gateway route pointer w/o free'ing a reference to the
route installed by the first thread. In practice this would probably just
fix a lost reference that would result in a route never being freed.
This fixes panics observed in rt_check() and rtexpunge().

commands will be run.
2. Rework the stop routine using ideas from brooks and delphij.
Specifically I am duplicating a lot of code from rc.subr's stop routine
so that this one will behave more like the one in rc.subr, but use rndc
to kill the daemon (or regular kill if that fails). This also avoids
the problems related to using killall if rndc fails, which is bad if
you're running more than one named on the same box.
3. Take a concept from gshapiro and allow the rndc.key file to be
owned by root OR the named_uid user.

since revision 1.1. Specifically, neither traversal of the vm map checks
whether the end of the vm map has been reached. Consequently, the first
traversal can wrap around and bogusly return an error.
This error has gone unnoticed for so long because no one had ever before
tried msync(2)ing a region above the stack.

This allows libdtrace to determine the exact file from which
a kernel module was loaded without having to guess.
The kldstat(2) API is versioned with the size of the
kld_file_stat structure, so this change creates version 2.
Add the pathname to the verbose output of kldstat(8) too.

aligned, GCC 4.2.1 also generates code for sendudp() that assumes
this alignment. GCC 4.2.1 however doesn't 32-bit align wbuf, causing
the loader to crash due to an unaligned access of wbuf in sendudp()
when netbooting sparc64. Solve this by specifying wbuf as packed and
32-bit aligned, too. As for lastdata and readudp() this currently is
no issue when compiled with GCC 4.2.1, though give lastdata the same
treatment as wbuf for consistency and possibility of being affected
in the future. [1]
