  * Add userspace support for AppArmor signals and ptrace mediation
    (LP: #1298611)
    + debian/patches/mediate-signals.patch,
      debian/patches/change-signal-syntax.patch: Parse signal rules with
      apparmor_parser. See the apparmor.d(5) man page for syntax details.
    + debian/patches/change-ptrace-syntax.patch,
      debian/patches/mediate-ptrace.patch: Parse ptrace rules with
      apparmor_parser. See the apparmor.d(5) man page for syntax details.

      debian/patches/test-ptrace-rules.patch,
      debian/patches/update-tests-for-new-semantics.patch: Update existing
      tests and add new tests for signal and ptrace mediation
    + debian/patches/fix-garbage-in-preprocessor-output.patch: Fix bug causing

      statements
    + debian/patches/fix-double-comma-in-preprocessor-output.patch: Fix bug
      causing apparmor_parser preprocessor output to contain double commas
      after some rules
    + debian/patches/symtab-tests-and-seenlist-bug.patch,
      debian/patches/add-profile-name-variable.patch: Add ${profile_name}
      variable for use in profiles when rules need to specify the current

    + debian/patches/fix-names-treated-as-condlistid.patch: Fix
      apparmor_parser bug that caused mount and dbus rules to fail for sets of
      values

  [ Jamie Strandboge ]
  * debian/patches/update-base-abstraction-for-signals-and-ptrace.patch:

    page to document signal rules, ptrace rules, and variables for use in
    AppArmor profiles

    profile to allow libvirtd to send signals to and ptrace read the dnsmasq
    process

    profile for permissions needed in newer chromium-browser versions and add
    the rules needed for AppArmor ptrace mediation

  [ Tyler Hicks ]
  * Add new rule type support to aa.py to fix tracebacks when using the Python
    utilities in apparmor-utils on systems with AppArmor profiles containing
    previously unsupported rule types
    - debian/patches/python-utils-file-support.patch: Support path rules
      containing the "file" prefix (LP: #1295346)
    - debian/patches/python-utils-signal-support.patch: Parse and write signal
      rules (LP: #1300316)
    - debian/patches/python-utils-ptrace-support.patch: Parse and write ptrace
      rules (LP: #1300317)...
