Hi,
I am trying to figure out what part in the kernel code is the point
from where I can get source and destination ip-address, port, security
labels (selinux etc) from a packet before I export it to application
space for my needs. Any hints?
Shaz.

Look into the netlabel and xfrm code. In Smack it gets dealt with
in smack_lsm.c, but Smack only uses netlabel. SELinux spreads the
handling into a number of files, including hooks.c, netlabel.c, xfrm.c,
and ss/services.c.
