Hi everybody,
I was wondering if someone could tell me where I could find info about the
linkages between the various kernel networking data structures...the more
I read the header files (and the comments that go with them!) the more I
get confused...also, is there any serious design difference between the
4.4 BSD implementation and the linux network implementation. For instance,
in 4.4 BSD, TCP maintains its own protocol control block (unlike
udp).Where do i find the TCP protocol control block...to me it looks like
struct sock{} incorporates everything, or am I way off?
Also, if I wanted to add a per-connection variable which measures the
number of bytes sent out for that connection (for measuring some kind of
rate), would I better off including it in tcp_opt or in struct sock{}?
Thanks,
Hari
