The chapter that deals with setting up the kernel (Linux-x.y.x) is too limited in my opinion. I do realise that my extension is out-of-scope for the LFS developers, but I do think that many will benefit from it, especially if you want to tinker with kernels and their settings.

Oops (pet name for kernel panic) mostly spits lots of martian traces that include stack addresses, registers and its value, EIP, etc.

To know the culprit line that caused panic, decode the address to line as follows:
EIP wud luk like...
Code:
EIP: [] ip_check+0x45a/0x21a [ip_tables] SS:ESP 0049:c098281a

Probably, if you were linked here, you had troubles when someone gained root at your system.

The problem I'm writing this post about is kernel/software cracking.
Many people had troubles with crackers who gained root at their servers or desktops. Some of users had all permissions and privileges set up correctly but still got kernel BOF'ed and rooted.

Download the latest kernel source from kernel.org. I'll be using here kernel 2.6.32 source and 2.6.32.1 patch. So you understand that you don't need to download the whole kernel source every-time a...
