Rule Set Based Access Control (RSBAC) is an open source security extension for current Linux kernels. It is based on the Generalized Framework for Access Control (GFAC) and provides a flexible system of access control implemented with the help of a kernel patch. All security relevant system calls are extended by security enforcement code. This code calls the central decision component, which in turn calls all active decision modules and generates a combined decision. This decision is then enforced by the system call extensions. This version is for the 2.6 kernel. This release is for Linux kernel 2.6.29.2. A significant speedup and even better SMP scalability are expected from the new RCU based list locking. The most important changes since 1.3.5 are the addition of VUM (Virtual User Management) support, OTP support for UM, support of ANY for NETLINK control, checking of CLOSE requests in RC, the addition of SCD target videomem and kernel attribute pagenr, ext4 secure delete support, and many small bugfixes too. Generic lists were changed to use RCU instead of rw spinlocks.
