Not that I am doing development on it, but "me too" :)

I have an M-Audio USB audio device which used to work OK in stable, but 
doesn't in -current :(

I am cvsup'ing to get the latest stuff and I will try it out and see how it 
goes.

Good Information about ipfw

Is there a good, definitive, source of information for implementing ipfw
firewall rules.  I had to research for almost a week just to find out
how to do bandwidth limiting with freebsd.  (3days just to find out if
freebsd does this, and then another two just to find out what dummynet
is, and then I found out that it was in the man page.)  Where is the
list of all these obscure programs, and features, that are not a
unreadable as most man pages.  

I would also like to know what the point of most manpages are.  90
percent of them just list abitrary commands, as though you are supposed
to know how to use the program in the first place.  There are almost
never any useful informatin about implementing the program that the
manpage is supposed to explain, but does not. 

I have not been able to locate any book on the one firewall, that seems
to be at the heart of any good Freebsd firewall setup. 

Please help this wayward soul.

Thanks fellow bsders.

Good Information about ipfw

Is there a good, definitive, source of information for implementing ipfw firewall rules. I am familiar
with the man pages, howerver, a list of arbitrary functionality, without any clue as to how to actually
empliment them is of no use to me.
I am in Mozul, Iraq, and I have limited time on the Internet, and far less resources than I did before I got
activated to come over here. 
I would also like to know what the point of most man pages are.  90 percent of them just list arbitrary

decomment, assuming it simply strips c/c++ comments from source files,
could be implemented with a few lines of a lex spec.

Where did you look?  I just spent about 2 minutes and found question
12.22 in the FreeBSD FAQ "Where can I get a bandwidth management tool?"

Man pages typically references not tutorials. They list ALL the command
line options for the programs they document not arbitrary ones.

Try 'man firewall'.

ipfw cached ucred patch

All,

Currently, when you have any rules which contain UID/GID
constraints, ipfw will lock the pcb hash and do a lookup
to find the pcb associated with that packet -- 
One for each constraint.

I have written a patch in attempt to minimize the impact
of PCB related lookups for these type of firewall rules.

This patch will have the following effects on firewalls which
contain UID/GID constraints:

 o Greatly reduce the locking contention associated
   with PCB lookups.

 o Increase the performance of firewall in general by making
   PCB lookups O(1) rather than O(n) (where n represents
   number of UID/GID constraints in the ruleset)

It would be greatly appriciated if people who are running ipfw
rules sets containing UID/GID constraints tested this patch
and reported any success or failures.

The patch can be downloaded from:

You can optimize it even further by directly copying the uid/gid

  are you going to convert mbuf tag allocator to UMA? Now
tags are allocated with malloc(). AFAIK, tags are used heavily in pf,
and forthcoming ALTQ. Moving to UMA should affect their performance
positively.

Here's some info below.  Perhaps once you figure it all out, you
could write up a "cheatsheet" to help others.

ifconfig.c developer manual

Hello Everyone,

I know most of you here already have extreme knowledge about freeBSD's
ins and outs.
I just want to ask specifically regarding FreeBSD's ifconfig.c's
functions and what does 
each function do.

No one can give me a developer's manual for such and I really need
someone to interpret 
each function for me.

Any help would be very much appreciated.

Thank you and best regards to one and all.
