How to create postmortem data logger in Linux ?

[vlc_chowdary]

Hi,
This is VL Chowdary, a software engineer in Bangalore,India.I am currently working on a project that deals with "Creation of Postmortem data log file on Linux platform".
The project is on Fedora 12 with Kernel2.6.31.5 version.
For that i need following things.
1. Find the location of core utility in the kernel.
2. Find the source file that consists of actual implementation of the core utility (On Fedora's kernel 2.6.31.5)
3. Based on that i want to implement a core file with my own project requirements.
4. Build the kernel with the above implemented corefile replacing the existing one.

I couldn't get the source file that contains the implementation of core utility.
Please help in the project for further proceedings.
Advance thanks to all repliers.

Thank you,

I'm not sure what your mean by core-utility? Are you referring to a file /proc/core ?
If so,did you check the proc file system code?

The core utlility is a source file that contains implemented code for generating core file.
In general,the SIGSEGV signal causes this core dump.

Can any body help me in finding the definition of the signal handler for SIGSEGV in Linux kernel...

Thanks
