* MFS: sync the ipfw/dummynet/bridge code with the one recently mergedluigi2001-11-041-2/+3
| | | | into stable (mostly , but not only, formatting and comments changes).
* Make it so dummynet and bridge can be loaded as modules.ps2001-10-051-11/+8

* Two main changes here:luigi2001-09-271-2/+2
| | | | | | | | | | | | | | | + implement "limit" rules, which permit to limit the number of sessions between certain host pairs (according to masks). These are a special type of stateful rules, which might be of interest in some cases. See the ipfw manpage for details. + merge the list pointers and ipfw rule descriptors in the kernel, so the code is smaller, faster and more readable. This patch basically consists in replacing "foo->rule->bar" with "rule->bar" all over the place. I have been willing to do this for ages! MFC after: 1 week

* Document data structures and operation on dummynet so next timeluigi2001-01-171-42/+117
| | | | | I or someone else browse through this code I do not have a hard time understanding what is going on.
* Some dummynet patches that I forgot to commit last summer.luigi2001-01-161-0/+4
| | | | | | One of them fixes a potential panic when bridging is used and you run out of mbufs (though i have no idea if the bug has ever hit anyone).
* Implement WF2Q+ in dummynet.luigi2000-06-081-26/+149

* Support for stateful (dynamic) ipfw rules. They are veryluigi2000-02-101-12/+2
| | | | | | | | similar to ipfilter's keep-state. Look at the updated ipfw(8) manpage for details. Approved-by: jordan
* Implement per-flow queueing. Using a single pipe config rule,luigi2000-01-081-46/+95
| | | | | | | | | | | | | | | | | | now you can dynamically create rate-limited queues for different flows using masks on dst/src IP, port and protocols. Read the ipfw(8) manpage for details and examples. Restructure the internals of the traffic shaper to use heaps, so that it manages efficiently large number of queues. Fix a bug which was present in the previous versions which could cause, under certain unfrequent conditions, to send out very large bursts of traffic. All in all, this new code is much cleaner than the previous one and should also perform better. Work supported by Akamba Corp.
* Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL"peter1999-12-291-2/+2
| | | | | | is an application space macro and the applications are supposed to be free to use it as they please (but cannot). This is consistant with the other BSD's who made this change quite some time ago. More commits to come.
* IPSEC support in the kernel.shin1999-12-221-1/+2
| | | | | | | | pr_input() routines prototype is also changed to support IPSEC and IPV6 chained protocol headers. Reviewed by: freebsd-arch, cvs-committers Obtained from: KAME project

* assorted dummynet cleanup:luigi1999-05-041-3/+4
| | | | | | | + plug an mbuf leak when dummynet used with bridging + make prototype of dummynet_io consistent with usage + code cleanup so that now bandwidth regulation is precise to the bit/s and not to (8*HZ) bit/s as before.
* Tidy up some stray / unused stuff in the IPFW package and friends.peter1999-04-201-2/+1
| | | | | | | | - unifdef -DCOMPAT_IPFW (this was on by default already) - remove traces of in-kernel ip_nat package, it was never committed. - Make IPFW and DUMMYNET initialize themselves rather than depend on compiled-in hooks in ip_init(). This means they initialize the same way both in-kernel and as kld modules. (IPFW initializes now :-)
* Move kernel-only declarations to within #ifdef KERNELarchie1999-01-231-4/+9
