* The layer 3 (signalling) of NgATM netgraph node: ng_uni. This nodeHartmut Brandt2003-11-073-0/+1203

* Replace the lock-less algorithm for the free item list with a moreHartmut Brandt2003-11-051-64/+36
| | | | | | | | | | | | | | conservative lock. The problem with the lock-less algorithm is that it suffers from the ABA problem. Running an application with funnels a couple of 100kpkts/s through the netgraph system on a dual CPU system with MPSAFE drivers will panic almost immediatly with the old algorithm. It may be possible to eliminate the contention between threads that insert free items into the list and those that get free items by using the Michael/Scott queue algorithm that has two locks.

* Add two loader tuneables that allow one to change the maximum number ofHartmut Brandt2003-03-021-1/+11
| | | | | | | | | | | | | | | | | | | | | queue items that can be allocated by netgraph and the number of free queue items that are cached on a private list. Netgraph places an upper limit on the number of queue items it may allocate. When there is a large number of netgraph messages travelling through the system (100k/sec and more) there is a high probability, that messages get queued at the nodes and netgraph runs out of queue items. In this case the data flow through netgraph gets blocked. The tuneable for the number of free items lets one trade memory for performance. The tunables are also available as read-only sysctls.

* Some more updates for the new world order:Bill Paul2003-02-261-24/+37
| | | | | | | | | | | | | | | | | | | | | | | - Make transmission of packets work again. This stopped working because ether_ifattach() was forcing ifp->if_output to be ether_output() and clobbering our attempt to override this vector with a pointer to ng_fec_output(). Move the overriding of ifp->if_output to after ether_ifattach(). - Abandon the use of the netgraph ng_ether_input_p hook for snagging incoming frames, and instead override the ifp->if_input vector for interfaces that have been aggregated into our bundle. (I would have loved to have written things this way in the first place, but I didn't want to have to be the one to implement the if_input hook and change all the drivers.) This avoids collisions with the ng_ether module, which uses the same hook. Each aggregated device now calls ng_fec_input() directly, which then fakes up the rcvif pointer before invoking ifp->if_input itself. This module should actually work now.

| | | | | | | | | | | | | | | | | | changed since this code was written: - The ng_ether_input_p hook only accepts two arguments now: the pointer to the ether header structure is gone. - It's no longer necessary to cons up a fake ether header before passing incoming packets to BPF_MTAP(). ng_fec_input() has been modified to account for these two changes. Running tcpdump on fec0 should work now. PR: kern/46720 Notes: svn path=/head/; revision=111537
