Hi,
We're looking for some help with respect to AppArmor child profiles. In a scenario where 'parent_process' spawns (fork and exec) a number of child processes, we would like to achieve the following - if a profile exists for any child process, use it. Otherwise, don't inherit the parent's profile - instead, inherit a different default profile (presumably specified as a nested profile within the parent). We have taken a good look at the use cases for the 'p', 'c', and 'i' exec flags, however, no combination of these flags seems to solve the problem: a) px - Uses the child's profile (different) if it exists b) cx - Uses the child's profile (nested) if it exists c) pix - Uses the child's profile (different) if it exists, else inherits the parent's profile d) cix - Uses the child's profile (nested) if it exists, else inherits the parent's profile Here's an example of what we would like: Parent Process' Profile: profile parent { ... ... profile child_default { ... ... } ... ... } Is there a way by which we could say this: for all children spawned by parent, check whether there exists a child profile (either a different profile in the file system, or a nested child profile) and if so use it, else use profile 'child_default'? We understand that doing this for a parent that spawns around 5 children just involves creating 5 different profiles for each of them, and specifying exec transitions on each. However, doing this for a process that spawns more than 20 children (something like the init process) becomes cumbersome. Does AppArmor provide support for this out of the box? Thank you.
