Kernel Development

Enhancments:

• change Kconfig to use select instead of depends (eparis RH BZ# 228899)
• remove secondary module stacking code (eparis RH BZ#231890)
• security_port_sid needs optimization (eparis RH BZ#234531)
• explicitly set i_ino on all creations in selinuxfs (eparis RH BZ#235248)
• allow undefined classes and permissions in kernel (eparis RH BZ#235280)
• Reduce memory usage of selinux structs (eparis RH BZ#235284)
• fine grained enforcement of sysfs objects (RH BZ#228902)
• labeled net needs better passing of labels over loopback
• additional support of a security netfilter table for secmark/net forwarding
• Normalize the SELinux in-kernel API.
• Namespacing of SELinux global functions and variables.
• NFSv4 support
• KVM controls
• Finer-grained proc checking (so that we don't require full ptrace permission just to read process state),
• Improve/fix ioctl checking (see prior discussions on selinux and linux-security-module list),
• Revoke memory-mapped file access upon policy change or setxattr.
• Real device labeling and access control (i.e. bind a label to a device in the kernel irrespective of what device node is used to access it so that a process that can create any device nodes at all can't effectively bypass all device access controls just by creating an arbitrary node to any device in a type accessible to it),
• Full APIs for getting and setting security contexts of sockets and IPC objects.
• Polyinstantiated ports
• Increased granularity for Generic Netlink

Know Bugs: exporting nfs with the nohide options causes problems on ia64 clients (struct nfs_mount_data corruption)
