Am implementing a packet filter in solaris 9. Am able to create a STREAMS
module and insert it between the IP and NIC. Am able to see the upstream and
downstream messages flowing through my module.
How do i extract the IP addresses from mblk_t in case of downstream messages ?
I need to extact the destination IP address and do some processing based on
that. Can some one throw me some light on how to get this done ?
Well, I was going to say "look at what the pfil module used to do",
but once a file is removed from the source base (goes into the
"deleted_files" tree internally), it appears that we no longer ship
it out into CVS for opensolaris (there are no "Attic" directories
that I can see via the web interface, anyway.)
Instead you can have a look at the song and dance that IPFilter
uses - download http://coombs.anu.edu.au/~avalon/pfil-2.1.13.tar.gz
and look in the file "SunOS/pfildrv.c". It's really an unpleasant thing
to be a STREAMS module between IP and NIC drivers.
