Raw (Ethernet) Sockets over io-net net stack on QNX 6.3.2   
Hi,

I am attempting to port an application to run under QNX version 6.3.2. 
The application makes use of the socket(AF_PACKET,SOCK_RAW,0) function call to allow it to create its own ethernet based
 protocol packets. It also makes use of QOS and VLANs in the extended ethernet header.

As far as I can see this functionality does not seem to exist in the io-net network stack include with 6.3.2 , so my 
question is what is the best approach I should take to migrate the application.

Do later version of QNX support this functionality? I know there is a new network stack;- io-pkt. Does this give me what
 I need, and because we are stuck as 6.3.2 is it possible to migrate this stack to run under 6.3.2?

Any ideas, suggestions would be greatly appreciated!!

Thanks

Phil

The closest we have is BPF under io-pkt.

Hi Sean,

Is this true for all versions of QNX? Can I do the same with 6.3.2 as I can do with 6.5? Or is an upgrade required?

It's true of io-pkt which wasn't released under 6.3.2.  It's theoretically possible to run it under that version but 
that's not a supported or tested configuration.

  It's not theoretical issue ... it's simply possible to implement a raw 
socket interface.
I see here customers asking for a raw socket interface since more than 
20 years  .... how long will you ingnore your customers needs ?

Re: Raw (Ethernet) Sockets over io-net net stack on QNX 6.3.2   
Hi,

Please read the whole thread.  We have the ability to send
raw packets in bpf.  It's not fully supported in 6.3.2 and
it's not the linux interface.  The next version will also
have tun / tap.

Regards,

Re: Raw (Ethernet) Sockets over io-net net stack on QNX 6.3.2   
Hi Phil

We achieved similar functionality on io-net using io-net filter module
such that is has ethernet below it and IP above it. so, this way we
can get access to all ethernet frames entering the system and can
generate ethernet frames of our own.

Other scenario is hacking the network driver code but that might not
be a great design.

Re: Raw (Ethernet) Sockets over io-net net stack on QNX 6.3.2   
By network filter I assume you don't mean BPF.

If I understand things correctly BPF (Berkley Packet Filter) can only be used at 6.3.2 to read raw packets not send them
, or has this changed?

Re: Raw (Ethernet) Sockets over io-net net stack on QNX 6.3.2   
No Phil, I did not refer to BPF, I meant custom module written to be
plugged in at runtime into qnx io-net framework. Look around for
up-filter in qnx networking documentation.......
