Hi Dave,
I'm Tuu Le. I'm trying to port some STREAMS drivers from UNIX SCO over to
LINUX STREAMS (LiS). In my ipf (internet packet filter) SCO driver, I
have to use 'struct ip'
which contains 'ip_v', ip_p, ip_src
...fields etc. So, that why I have to include <netinet/ip.h> for
supporting that struct. But when I port to LiS, if I keep including
<netinet/ip.h>, that won't compile, but if I include
<linux/ip.h>, that will compile. However , <linux/ip.h>
doesn't have 'struct ip' and ip_v, ip_p...fields. So, how can I use
<netinet/ip.h> for kernel headers for my driver? Or do you have any
idea how to use other kernel header that will include 'struct ip' for my
LiS driver?
I also attach two files, one for my driver and
another for makefile. If you have time, please take a look for
me.
Thanks in advance!
Tuu

/*
* STREAM MODULE (ipf.c) -- push between ppp and ip multiplexer.
*
* This module monitors data and ioctls going to and from a STREAM device in
* real time. It allows Selected Directed Broadcast messages to be passed
* up the stream. The stream module will also allow us to transmit with
* a fake IP source address for testing, and allow us to receive messages
* addressed to our simulated subscribers. This module is the key for our
* network manipulation in a testing environment. The serial device sets
* in promiscuous mode which allows this module to look at all the messages
* coming off the PPP net. The IP multiplexer is relied upon to sort
* or discard the appropriate messages. For debugging or monitoring of
* the PPP network the printout is on the console if cmn_err uses a "^"
* or to the putbuf with the "!". Usage is to push it into a Stream
* before the IP multiplexer.
*
* To install the STREAM MODULE perform the following:
* 1. su to root.
* 2. SCO5 USE ONLY: cc -c -Zp1 -DINKERNEL -D_INKERNEL ipf.c
* 3. cp ipf.o Driver.o
* 4. Ensure these files are in the current directory:
* a. Driver.o
* b. space.c (cp ipf_space.c)
* c. Master (ipf - Si ipf 0 0 1 4 -1)
* d. System (ipf Y 1 0 0 0 0 0 0 0)
* 5. /etc/conf/bin/idinstall -d ipf #removes previous module versions
* 6. /etc/conf/bin/idinstall -a -k ipf #installs module
* 7. cp space.c /etc/conf/pack.d/ipf
* 8. /etc/conf/bin/idbuild #rebuilds kernel
* 9. SCO5 USE ONLY: ppplink will take care of this step when tss
* runs or you can add this option to /etc/ppphosts:
*
* filter=tss
*
* This entry must be added to /etc/pppfilter:
*
* tss bringup \
* pass dst net 0.0.0.0\
* keepup
*
* The system will automatically push the module on the device.
*
* 10. reboot system.
