Linux 3.2: backports some features from mainline kernel (3.7)?
Hi, Kernel 3.7 is officially out. This Linux release includes many improvements practically in every aspect. Many changes also concerns security. Very interesting are: Cryptographically-signed kernel modules and - long awaited - symlink and hardlink restrictions (already in Linux 3.6), but it broke some programs, so it has been disabled by default, right? Those features/changes are very interesting from security point of view. With signed kernel modules, various distributions can lock down their kernels. symlink and hardlink are just a long-standing, much needed class of security. I would like to ask, if some of 3.7 kernel features (such as those mentioned) will be backported to Testing kernel (3.2)? I know Wheezy has now been frozen and in consequences this means that no more new features will be added etc. But there is still some time to official release and those features, could be tested very well. Are there any plans to do this? Best regards!
