Hi, Thank you for your response.. I wonder if Is it really only netlink problem? Their are fee problems in the logs.. I dont kbow if they all related only to netlink (prctl immutable for example).. I also saw oncompatibilities in socket.c .... Btw: I tried to enter the link you sent and it asked for username and password.. its not public review?
