Hi Hari,
I think you should definitely add your field to the
tcp_opt struct (instead of directly adding it to
struct sock) , as that is where most of the
TCP-related stuff is being maintained in 2.2 for each
connection..
About documentation, theres a good paper at
http://pubpages.unh.edu/~gherrin/project/linux-net.html
I havent seen many texts covering the 2.2 kernel, so
using old sources of info along with a look at the
source code seems to be the only way to go.. infact if
you find any books/papers (online or otherwise)
catering to the topic, please let me know, as I would
be interested too!
