Hello all, Firstly let me say thanks on your efforts of putting some kernel development information together (on the website) and creating a forum for new kernel developers that is required below the linux-kernel@vger.kernel.org level. Secondly, I searched the website thoroughly but couldn't find any documentation on net's XFRM and especially dealing with IPsec functions (xfrm_policy, xfrm_state, xfrm_selector etc). I've been looking for some documentation about it for a while and it seems to be blatantly missing from the web and books also. Finally, is there an easy way to print in a human readable format the IPv6 address of the xfrm_address_t union? (see http://lxr.free-electrons.com/source/include/linux/xfrm.h?v=2.6.36#L10 ) Thanks a lot, Panos
