The problem here is that udbinfo.listhead and ripcbinfo.listhead are
not initialized during the device probe/attach phase of the kernel
boot process. So if, for example, a network driver calls ether_ifattach()
in its foo_attach() routine and then decides that something is wrong
and calls ether_ifdetach() to reverse the process, we will panic trying
to dereference the uninitialized list head pointers. (Though the
same sequence of events performed after the kernel has come up works
file, i.e. doing kldload if_foo from multiuser.)
Change this to:
if (udbinfo.listhead != NULL)
in6_pcbpurgeif0(LIST_FIRST(udbinfo.listhead), ifp);
if (ripcbinfo.listhead != NULL)
in6_pcbpurgeif0(LIST_FIRST(ripcbinfo.listhead), ifp);
to avoid the NULL pointer dereferences.

These changes also introduce arguments to m_tag_copy and m_tag_copy_chain

that should be better.
The old code counted references to mbuf clusters by using the offset
of the cluster from the start of memory allocated for mbufs and
clusters as an index into an array of chars, which did the reference
counting. If the external storage was not a cluster then reference
counting had to be done by the code using that external storage.
NetBSD's system of linked lists of mbufs was cosidered, but Alfred
felt it would have locking issues when the kernel was made more
SMP friendly.
The system implimented uses a pool of unions to track external
storage. The union contains an int for counting the references and
a pointer for forming a free list. The reference counts are
incremented and decremented atomically and so should be SMP friendly.
This system can track reference counts for any sort of external
storage.
Access to the reference counting stuff is now through macros defined
in mbuf.h, so it should be easier to make changes to the system in
the future.
The possibility of storing the reference count in one of the
referencing mbufs was considered, but was rejected 'cos it would
often leave extra mbufs allocated. Storing the reference count in
the cluster was also considered, but because the external storage
may not be a cluster this isn't an option.
The size of the pool of reference counters is available in the
stats provided by "netstat -m".
