Tools

Parser

  • replace/cleanup front end
  • split into separate tools
    • common parsing library
    • common computation library
    • common interface (loader) library
    • compiler
    • loader
    • verifier/analysis tool

New tools

  • profile merge tool
  • gui profile editing tool
  • gui control tool (init script interface)
  • new learning tools (replace genprof/logprof)
    • terminal (ncurses)
    • gui
  • static binary analysis for profile generation
  • sandbox generation tool
    • basic profile setup
      • (autodep + default rule set)
      • load profile
    • setup jail
      • chroot (no sharing)
      • union fs/mount + bind mount
        • share data (control reads with rules)
        • capture writes

    • OSD
      • system bus
      • direct to user session bus
      • way to kick off profile update tool
    • email, ...
  • aa-confine - run cmd confined by a <profile>. If <profile> does not contain permissions to exec <cmd> then the exec will fail. The profile used must already be loaded in the system unless a template is specified with -t. Eg:
 aa-confine guest_user ls -l /home
  • aa-top - watch apparmor profiles
  • aa-ls - list file confinement (profiles/permissions)

Front End (User space)

Features that are can be completely implemented in user space with current backend

  • x dominance analysis - allowing for overlapping x rules
  • pcre based rules (expose more matching ability)
  • rule subtraction or some such allowing for more expressive rules

Back End (Kernel)

The back end (kernel module) exposes to the front end a set of features, that the front end then maps to and leverages. As such the back end doesn't generally have new features that can be implemented separate from the front end. There are however general cleanups that can be done in the work items list.

  • No blockers for moving upstream Linux. Have commitments it will go in once all issues are addressed. Work is ongoing and pushed upstream for (re)review. Inclusion is 2.6.36 is expected.
  • BSD kernel backend? Is it possible, is it desirable. Would be a new implementation.
  • verify/deal with btrfs snapshots

Language/features improvements

  • new language - possibly move to a new language?
    • separate out x rules from others
    • remove m?
    • permissions come before filenames?
  • direct learning connection to kernel (netlink)
  • multiple names for a profile (extend upon regex profiles)
  • profile aliasing - share profile from different namespaces etc.
  • delegation
  • kill rules
  • extended conditionals rules
  • extended capability mediation
  • dynamic loadable variables
    • per namespace
    • per user
    • per profile
  • user definable profiles
  • networking
    • stage1 socket, outbound control
    • table based rules
    • labelled packets handled by ipc
  • ipc
    • per ipc type control
    • generic passing of info from/to domain
    • labelled network communication
  • mount mediation
  • chroot (improvements to chroots are handled)
  • disconnected paths
  • filesystem namespaces (bind mounts)
  • keys
  • regexs in includes (e.g. include <dir/*.conf>)

Documentation

  • update techdoc
  • wiki cleanups
  • policy language document
  • bring man pages up to date

Resource usage improvements

  • Policy memory usage and computation time (high)
    • Ideas
      • could improve with table compression
        • better memory usage, speed improvements
        • need to evaluate different methods, potentially switching away from a strict DFA
      • kernel memory usage multiple large compressed dfas
      • user space memory usage, rules, expression trees, uncompressed dfas, compressed dfas
      • dominant part of policy compilation is dfa compressions
    • Possible DFA short term improvements
      • improve compression speed (parser work)
      • share dfa (parser work)
      • improve dfa creation speed with set hashing
    • Possible DFA medium term improvements
      • DFA boolean operations and caching of partial compiled state
    • Possible DFA long term improvements
      • new compressions format
      • hybrid dfas?
  • Parser caching (high)
    • how to store files and time stamps in the cached files?
    • need to cache the metadata about the on-disk profiles used to generate a cache
    • sharing the parser's internal state when generating multiple profiles that share common abstractions
      • cuts down on memory usage (~50%) and compile time
      • needs some parser changes
  • atomic multiple profile load (low)
    • currently doing 1 at a time, want to load multiple at once (isomorphs generated during multi-profile parsing)
    • start with profiles with subpolicies like firefox and evince

Convert to default chroot relative profiles

AppArmor 3.0 will move to using chroot relative profiles by default. This means that profiles will resolve names relative to the chroot rather than relative to the namespace.

Goals

  • remove use of kernel ability that may be removed
  • Unify handling of chroot and fs namespaces from a policy pov
  • Deal with the disconnected path problem
  • provide backwards compatibility via flag etc while policy is migrated

Rational

chroots in the past were handled in a namespace relative manner. That is the chroot location is prepended to the path name. This is problematic for several reasons.

  • The ability to find this value may be removed at some point. If this goes away we currently don't have a good fix because of how policy is structured.
  • The profile names are not what are visible to the application
  • profiles used within a chroot are tied to a specific location, and thus not reusable for other locations ie. the prefix that is the chroot location that is appended to every rule
  • profiles intermix pre and post chroot rules
    • may give post chroot application more privilege than necessary
    • may give post chroot application access to files outside of the chroot
  • chroots are handled differently than filesystem namespaces. Filesystem namespaces are similar to chroot in concept except there is no way to get the fs location like there is the chroot location. Thus they need a different solution. Ideally chroot and fs namespaces should share a common solution for profile sanity
  • namespace relative chroot profiles don't work for profiles loaded within a chroot (ie. the chroot is a container virtuallizing an OS)
  • Profile stacking means that multiple profiles maybe applied to a single access request. There is a need to minimize path lookup operations which means restructuring the path code, and sharing a single path between all profiles.

Solution

  • Make profiles chroot relative - this mimics what happens with fs namespaces
  • Use labeling to handle files that are passed in and would result in a disconnected path
  • Use profile and namespace transitions to separate pre and post chroot policy. This structural changes allows profiles to contain just what is necessary pre and post chroot. It also allows better simulation of the current namespace relative behavior
  • Use namespace_relative profile flag for backwards compatability where necessary
  • Use kernel variables on the security context to store chroot location to allow continuing to offer "namespace_relative" compatibility

Problems

  • With chroot relative paths, paths outside of the chroot but in the namespace are still disconnected. Many chrooted apps have files that are opened and then past into the chroot. This needs a labeling or other solution
  • breaks current applications using chroot and profiles
  • breaks current unconfined behavior. System profiles are applied to applications run from within the chroot.

Work

  • Flag to support old behavior, namespace_relative (done)
  • Parser patch to default profiles to use chroot relative profiles (done)
  • Kernel patch to default complain and unconfined profiles to chroot relative (done)
  • implicit labeling to support disconnected paths
  • chroot rules
  • kernel variables?
  • Design for how unconfined should handle chroot and namespace transitions
    • parser implementation
    • kernel implementation
    • tools implementation
    • restructure policy to the pre/post chroot split


Potential Features

  • namespace controls (nice to have)
    • number and size of profiles loaded
    • masking off certain permissions for profiles
    • user profile load?
  • kernel user interface
    • netlink learning/logging interface -- to not flood logs (high)
      • move "complain mode" to netlink effectively
    • new sysfs style layout of supported features
      • compatibility patch for the old information files (high)
      • features directory (high)
      • new layout of profiles and namespace information
        • add md5s or shas of profile contents (low)
        • names of profiles, with replaced character, something else? (low)
  • passing delegation info and cache full permissions of labelling profile (nice to have)
    • deleted file labeling and exec
      • passing the fd and deleting caused a problem
    • deleted files
      • deleted and not shared, we give a pass. could do something with it
    • lazy unmount
      • caching full perms issue
  • exec time revalidation and delegation (medium)
    • file access time does a revalidation check (currently done)
    • improves file access times if revalidation happens at exec
    • slows down exec a bit
    • loses the ability to pass a file through a child that doesn't have permission
  • networking
    • pattern matching for labeling (medium)
    • packet labeling (iptables and secmark rule generation) (low)
      • has a prerequisite of multiple-profile atomic reload
    • cipso (nice to have)
  • creds & references, indirection, hashing
  • caching of state on objects? Cache full looked up permission
  • mounts
  • investigate hybrid model
    • directly integrate file labeling, when to label, when to allow relabeling
    • mv vs. cp behavior
    • single dfa, dfa intersection, Advantage single label model
      • needs caching and merging
      • needs to preserve previous labelings
  • pam_apparmor
    • change_profile
    • change_onexec
