Hey guys...!! I m pretty new to Linux..!! I've been given a task to modify network protocol(TCP in particular). So now i've to make few changes to the kernel which includes modifying few source files. So i want to know how can i go abt it. Till now i've explored various .c files of kernel(Eg.tcp.c,tcp_input.c etc etc)by referring few books. And now comes the important part of implementing it. So how exactly can i go abt it?? I went thru various threads like installing a kernel,compliling a kernel and other things. But i m not getting the exact sequence in which i should do it. I've installed fedora 10. But i cannot see any source files which i can modify. Where and how can i modify these files???Any form of suggestion will be of g8 help for a newbie like me... Thanks in advance..
Hi Onebuck.. Thanks for responding... Ok it is like this..!! We are trying to modify TCP,so that it is suitable for MANETs(Mobile Ad-hoc networks)where the packet loss is mainly due to error than the congestion. So to implement it i have to modify few source files related to transport protocol (mainly tcp_input.c file and few others ). So how can i go abt it??? As in, locating those files ,modifying and post modifying steps.
Hi Onebuck.. Thanks for those previous post links.. Now i got it.. I hv to actually hack the kernel..!! I'll try to search threads explaining steps to hack the kernel..!! I assume these should be the steps
1.Get the source codes
2.modify the kernel(make necessary changes in the files)
3.compile the kernel
4.install the kernel
Hope these are the steps in breif.
I'm trying use an extension of TCP (Freeze-TCP [1]) to mitigate the effect of mobility.
But when I'm doing the patch, it asks for files that do not exist in my usr/src/linux-.../net/ipv4 directory like tcp.c, tcp_output.c or tcp_minisocks.c.

Look at the faqs.
