4c165daa8d Teach portsnap how to ignore unwanted parts of the ports tree. A line
of the form "REFUSE foo" in portsnap.conf will result in parts of the
tree matching "^foo" being (a) not extracted by "portsnap extract", (b)
not updated by "portsnap update", and (c) not having any patches or new
ports downloaded by "portsnap fetch" or "portsnap cron". The example
shown in portsnap.conf demonstrates ignoring all the language categories.

As mentioned in portsnap.conf.5, the use of an imcomplete ports tree is
not officially supported; but this is something which many users have
requested, so I'm adding it anyway.

535e8b6e00 When we read data from socket buffer using soreceive() the socket layer
does not clear m_nextpkt for us. The mbufs are sent into netgraph and
then, if they contain a TCP packet delivered locally, they will enter
socket code again. They can pass the first assert in sbappendstream()
because m_nextpkt may be set not in the first mbuf, but deeper in the
chain. So the problem will trigger much later, when local program
reads the data from socket, and an mbuf with m_nextpkt becomes a
first one.

This bug was demasked by revision 1.54, when I made upcall queueable.
Before revision 1.54 there was a very small probability to have 2
mbufs in GRE socket buffer, because ng_ksocket_incoming2() dequeued
the first one immediately.

 - in ng_ksocket_incoming2() clear m_nextpkt on all mbufs
   read from socket.
 - restore rev. 1.54 change in ng_ksocket_incoming().

17dd22a407 Instead of caching the PID which opened the bpf descriptor, continuously
refresh the PID which has the descriptor open. The PID is refreshed in various
operations like ioctl(2), kevent(2) or poll(2). This produces more accurate
information about current bpf consumers. While we are here remove the bd_pcomm
member of the bpf stats structure because now that we have an accurate PID we
can lookup the via the kern.proc.pid sysctl variable. This is the trick that
NetBSD decided to use to deal with this issue.

Special care needs to be taken when MFC'ing this change, as we have made a
change to the bpf stats structure. What will end up happening is we will leave
the pcomm structure but just mark it as being un-used. This way we keep the ABI
in tact.

b58a5b21d1 o In pmap_remove_pte: always invalidate the page. Previously the page
was not invalidated if the PTE was not actually being removed.  In
   an UP kernel this didn't cause problems, because the new mapping
   would preempt the old one. In an SMP kernel this could lead to the
   use of stale translations when processes move between CPUs at the
   "right" moment.  This fixes the last of the obvious SMP problems
   and it should be safe to enable SMP by default now.
o  In pmap_remove_pte: minor code refactoring to avoid duplication.
o  Test all PTE pointers against NULL. Don't use implicit boolean
   tests.

b03a330dcf Fix panic when loading libiconv.ko on sparc64.
It seems that this issue only become obvious when compiled with -O2
on sparc64.

Since each struct iconv_converter_class has been initialized by
DEFINE_CLASS macro, not all members of struct iconv_converter_class
has been allocated on memory and cc_link member has not been
initialized, while iconv_register_converter() wanted to access it
with TAILQ.
Now we modify KICONV_CONVERTER macro and fix this bug.

61c98b99f2 Add a regression test to test two variations on the same bug: joining a
multicast group using a raw socket, then removing the interface on which
the group is found, and joining a multicast group using a udp socket,
then removing the interface on which the group is found.  An if_disc
interface is used as the interface on which to attach.

NB: A panic currently results from running this regression test, so do
so with caution.

516e4da61f Fix collision chain termination checks. The result of IA64_PHYS_TO_RR7
is never 0, so one cannot test for a NULL pointer after a physical
address is translated into a virtual pointer with said macro. Instead,
keep the physical address around and test it against 0. Note that
this obviously implies that a PTE can never be allocated at physical
address 0. This isn't exactly guaranteed, but hasn't been a problem
so far. We test the physical address against 0 for as long as the ia64
port exists...
