post 4.0...adoption of pfil(9) from NetBSD ?

2000-02-19 Thread Darren Reed
I was just having a quick peek at how ipfw works in FreeBSD-4 for IPv6, to see what's required for IP-Filter (hoping for a clean interface) and the response is "sigh". The old ipfw mechanism needs to be abandoned, IMHO. For those that aren't aware, pfil(9) in NetBSD used to provide two lists

Reading lpt status register in NIBBLE mode

2000-02-19 Thread Reinier Bezuidenhout
Hi ... I want to read the status register of the lpt port in NIBBLE mode. I want to do this wether there is a printer connected or not. What would be the best way to accomplish this ?? Should I use the ppi0 device with the PPIGSTATUS ioctl call, because if there is no printer connected I

The issue of one vs. multiple lists (per direction, interface, protocol, you name it) has been discussed some time ago. For sure multiple lists are a (minor, given that we can start the ipfw lists with a few of "skipto") performance improvement over a single one, at the possible price

Changing routing information is not a problem. For starters, with inbound packets, there is none. for outbound there is, and one of the biggest problems i had with dummynet (as an example) was that some code passed around route structures held in the stack, so you couldn't just keep a

Bug in ioctl() [Was: Help needed with ioctl() calls]

Firstly, the cross-post to -hackers seems appropriate but my apologies if it isn't. I am now certain that there is a bug in ioctl() (at least for setting the mixer). This started out as an attempt to fix a bug in xmms, but making a debug version of mixer(8) showed it to be affected the same
