In current implementation, only one md5 password is saved in the kernel and it brings in the problem for changing key: Changing key in the middle of tcp session will break the session unless new md5 password is updated at both ends at the same time (there is no window for key change). Does anybody know any patches currently exist to address this issue? I know rfc4808 is targeting to solve this issue. Does there any plan to implement rfc4808 for linux? Best Regards!
