with 16-bit ints, since u_short is promoted when it is passed to a
varargs function. gcc now warns about this. We always pass small
integers (this is well obuscated), so there are no conversion problems.
Fixed a related style bug (bogus cast).
-current, since offsetof() is defined a header under /sys so that
system sources don't need to have this wrong include.
This bug was only detected because my version of <stddef.h> has some
spelling fixes (s/field/member/g) and gcc is now sensitive to the spelling
of arg names in macros as required by standards (ISO C90 6.8.3...).
Get rid of the INTERNALSTATICLIB knob and just use plain INTERNALLIB.
INTERNALLIB now means to build static library only and don't install
anything. Added a NOINSTALLLIB knob for libpam/modules. To not
build any library at all, just do not set LIB.
Ipfw processing of frames at layer 2 can be enabled by the sysctl variable
net.link.ether.ipfw=1
Consider this feature experimental, because right now, the firewall
is invoked in the places indicated below, and controlled by the
sysctl variables listed on the right. As a consequence, a packet
can be filtered from 1 to 4 times depending on the path it follows,
which might make a ruleset a bit hard to follow.
I will add an ipfw option to tell if we want a given rule to apply
to ether_demux() and ether_output_frame(), but we have run out of
flags in the struct ip_fw so i need to think a bit on how to implement
this.

several reasons before. Fixing it involved restructuring the generic hash
code to require calling code to handle locking, unlocking, and freeing hashes
on error conditions.
Replace "command" with "utility" in the manual page & source to be more
consistent with the terminology used in the standard, and to hint that
shell builtin commands won't work.

fields as discussed in the commit to ip_fw.c:1.186
On top of this, a ton of non functional changes to clean up the code,
write functions to replace sections of code that were replicated
multiple times (e.g. the printing or matching of flags and options),
splitting long sections of inlined code into separate functions,
and the like.
I have tested the code quite a bit, but some typos (using one variable
in place of another) might have escaped.
The "embedded manpage" is a bit inconsistent, but i am leaving fixing
it for later. The current format makes no sense, it is over 40 lines
long and practically unreadable. We can either split it into sections
( ipfw -h options , ipfw -h pipe , ipfw -h queue ...)
or remove it altogether and refer to the manpage.
