RSBAC 1.3.0 has been released for both kernels 2.4.33.3 and 2.6.18. You can also try it with the latest RSBAC Live CD.

Improvements over the 1.2.x series:

• Speed and scalability:
  • Automatic online resizing of per-list hash table to reduce access time for large attribute lists significantly.
  • Limit number of items per single list to 50000, so real limit is at 50000 * nr_hashes.
  • Optimize cases in decision modules.
  • Change network templates to handle up to 25 ip networks and up to 10 port ranges.
  • Change aci, acl and auth devices lists to use RCU on 2.6 kernels.
• More control:
  • Optionally check CHANGE_OWNER for PROCESS targets also as CHANGE_OWNER on the new USER. This allows fine grained setuid control also in RC and ACL models.
  • Change named UNIX sockets to be new filesystem target type T_UNIXSOCK and unnamed to be new IPC type anonunix (like FIFO target for pipes).
  • RC role def_unixsock_create_type, which overrides the def_(ind_)fd_create_type. Default value use_def_fd.
  • UM password history with configurable length to avoid password reuse.
  • New request type AUTHENTICATE against USER targets. No authentication against RSBAC UM without this right in RC and ACL.
• JAIL Module:
  • More detailed JAIL decision logging for IPC and UNIXSOCK targets with rsbac_debug_adf_jail.
  • allow_parent_ipc to allow IPC into parent jail. Useful with Apache mod_rsbac and others.
  • add a flag to allow suid/sgid files and dirs.
• Other improvements:
  • Dazuko udev support.
  • Hide dir entries a process has no SEARCH right for.
  • Complete hook review with several small fixes.
  • Add rsbac_get_switch(value_p, switchable) that returns the module's status (on or off) and switchable status (can turn off, back on, ..).
  • Added similar output to the proc information (/proc/rsbac-info/active).
