Hi all, guys!
I'm now writing my thesis to degree at the university. My work is about the covert (or
subliminal) channels in network protocols. The practice part of my
work is to implement such channels and suggest the security mechanism.
I'm a Linux fan and developing it under 2.6.27 kernel.
The problem occured when I tried to use the mechanism of function

I have a PVR running Fedora 10 with a 250G ext4 filesystem, created when the disto was installed from DVD. The filesystem is used to store OTA HD TV, files on the order of 6-7G, created by an HD HomeRun, an ethernet-based HDTV tuner, capable of creating two files concurrently. I'm running an almost-latest 2.6.27 kernel, from the Fedora binary rpm.

Page to Process ID

I am trying to work on implementing a new caching strategy. I have a list of particular processes I am to manage the cache for. When a page is to be evicted via "shrink_page_list" I want to use that page and obtain the process ID, and see if that ID is in fact one in my to-manage list. Unfortunately, I have not been able to locate a routine to find the mapping between page to process ID.

I have a netfilter hook that changes some of the contents of the tcp header for all packets that fall in NF_IP_FORWARD category. Before passing on the packet, I need to of course calculate the TCP and IP checksums again, but I am unable to get the TCP checksums right.
Here are a few of the things i tried.
tcph->check = tcp_v4_check(len, iph->saddr, iph->daddr,

My embedded platform has two Silicon Images 3531 controllers. I'd like to force any attached sata devices [sda, sdb] to controllers 0 and 1 respectively. But if no device is attached to controller 0, then 'sda' will get assigned to the second controller. Seems like a simple problem but I've been wading through the libata code for a while.
