Title: child Cx transition to grandchild transition silently fails, and child Px to sibling transition silently fails Status in “apparmor” package in Ubuntu: Triaged Bug description: I noticed that apparmor does not transition from a child to a grandchild. Eg: /tmp/foo { /tmp/bar Cx -> bar, # works profile bar { /tmp/baz Cx -> baz, # does not work profile baz { } } } The following child to a sibling also fails: /tmp/foo { /tmp/bar Cx -> bar, # works profile bar { /tmp/baz Px -> baz, # does not work } profile baz { } } Attached is a tarball that shows how transitions work for ix, px, px to an uncle, px to a sibling, and cx to a grandchild. Run it with: $ tar -zxf ./apparmor.tar.gz $ cd ./apparmor $ ./poc.sh = profile-ix = start foo bar baz pass = profile-px = start foo bar baz pass = profile-px-sibling = start foo /tmp/bug/bar: /tmp/bug/baz: /bin/sh: bad interpreter: No such file or directory FAIL = profile-px-uncle = start foo bar baz pass = profile-cx-grandchild = apparmor_parser: Unable to replace "baz". Profile doesn't exist start foo /tmp/bug/bar: /tmp/bug/baz: /bin/sh: bad interpreter: No such file or directory FAIL Cleaning up removing profile-cx-grandchild removing profile-ix removing profile-px removing profile-px-sibling removing profile-px-uncle [1] $ Also, these transitions fail silently (both at compile and runtime), which might be related to bug #1045074 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/1045081/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
