Porting Linux kernel module to HP-UX 10.2

Rajesh A K — Thu, 01 Nov 2001 13:21:01 GMT

Sorry if this is not the appropriate forum.

We have developed a Linux loadable kernel module that uses TCP/IP socket services in kernel. We are studying the issues involved in porting this module to HP-UX 10.2. Appreciate if someone could answer our queries in this regard?
1. Are TCP/IP socket interfaces in kernel well known or published in HP-UX 10.2 ?
2. There may be kernel modules within HP-UX kernel that need networking features. How do these module interact with TCP/IP stack ?

Thanks much.

Products like sniff, snoop, lsof and others have been ported to hpux. here's a list of some hp info:

Hi Rajish,

As far as i know DLKM are only supported on UX11 look at this URL:

http://docs.hp.com/cgi-bin/fsearch/framedisplay?top=/hpux/onlinedocs/B3782-90716/B3782-90716_top.html&con=/hpux/onlinedocs/B3782-90716/00/00/23-con.html&toc=/hpux/onlinedocs/B3782-90716/00/00/23-toc.html&searchterms=dlkm&queryid=20011105-103532
At docs.hp.com you will find more information on the subject.

Hope this will help.

Harry,

Thanks for your pointers.

From the documentation on Networking architecture, found out that sosend() and soreceive() are the interfaces used in kernel. But, I dont think these are documented interfaces for driver developers. The driver that we developed uses TCP sockets in kernel to send/receive data. This is pretty much like khttpd in Linux 2.4.x kernel.

I would like to know if there are any documented interfaces in HP-UX 10.2 for using TCP sockets in kernel.

Thanks.
