* Two main changes here:Luigi Rizzo2001-09-271-2/+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 Notes: svn path=/head/; revision=84058

| | | | | | | The code (bridging and dummynet) actually worked fine! Notes: svn path=/head/; revision=71686
* Bring bridging code in line with the one which works on -STABLE.Luigi Rizzo2001-01-261-49/+97
| | | | | | | It compiles on -CURRENT, but I can not test functionality yet. Notes: svn path=/head/; revision=71666
* Assorted bugfixes:Luigi Rizzo2001-01-221-14/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | + configuration: make sure that the NUL at the end of the config string is properly detected and handled, and the stats passed up via sysctl properly reflect which interfaces do bridging. (The whole config support might make good use of some cleanup in the future). + fixed some bugs related to the corruption of multicast and broadcast packets: make sure that for those packets the entire IP + ethernet header is in the mbuf, not in a cluster, so that writes performed in that area by the upper layers do not affect us. + performance: when calling m_pullup, make room for the ethernet header as well, we are going to add it in right after. Also, change an m_dup back to m_copypacket. The former is not necessary anymore now, and it did not help, anyways. I will do a fast MFC because 95% of this patch is fixing bad bugs and i doubt anyone would test the fix in CURRENT. Plus the last two items mostly bring back some code which was already there in 4.0 times. Notes: svn path=/head/; revision=71392

* Lock down the network interface queues. The queue mutex must be obtainedJonathan Lemon2000-11-251-14/+2
| | | | | | | | | | | | | | | | | before adding/removing packets from the queue. Also, the if_obytes and if_omcasts fields should only be manipulated under protection of the mutex. IF_ENQUEUE, IF_PREPEND, and IF_DEQUEUE perform all necessary locking on the queue. An IF_LOCK macro is provided, as well as the old (mutex-less) versions of the macros in the form _IF_ENQUEUE, _IF_QFULL, for code which needs them, but their use is discouraged. Two new macros are introduced: IF_DRAIN() to drain a queue, and IF_HANDOFF, which takes care of locking/enqueue, and also statistics updating/start if necessary.

* Fixup (hopefully) bridging + ipfw + dummynet together...Bosko Milekic2000-11-231-2/+16
| | | | | | | | | | | | | | | | | | | | | * Some dummynet code incorrectly handled a malloc()-allocated pseudo-mbuf header structure, called "pkt," and could consequently pollute the mbuf free list if it was ever passed to m_freem(). The fix involved passing not pkt, but essentially pkt->m_next (which is a real mbuf) to the mbuf utility routines. * Also, for dummynet, in bdg_forward(), made the code copy the ethernet header back into the mbuf (prepended) because the dummynet code that follows expects it to be there but it is, unfortunately for dummynet, passed to bdg_forward as a seperate argument.

* In theory, m_dup should not be necessary, as m_copypacket should beNick Sayer2000-09-251-3/+3
| | | | | | | | | | | | | | | sifficient. But somewhere (I believe in the UDP stuff), someone is overwriting an mbuf without calling m_pullup() first. This results in broad- and multi-cast traffic that is passed through the bridge getting corrupted. This should be backed out when there is some assurance that the upper layers (and I suppose all of the device drivers) are fixed. Suggested by: archie Notes: svn path=/head/; revision=66359

The good news: net result of 1016 lines removed, and this should make bridging now work with *all* Ethernet drivers. The bad news: it's nearly impossible to test every driver, especially for bridging, and I was unable to get much testing help on the mailing lists.
