Michael Kerrisk 627e4074b4 user_namespaces.7: Fix description of inheritance of capabilities across nested namespaces 
Based on input from Eric Biederman

    Calling cap_capable asks: Does the current process have
    capability X in userns U.

    I see three ways you can have that capability.

    1) The current process can be in user namespace U and directly
       have capability X.

    2) The current process can be in the parent of namespace U and
       its euid can be the euid that created user namespace U.

    3) You can have be have the capability X in a user namespace
       that is an ancestor of U.

    Coming from the direction of your manpage text.

    With respect to capabilities, the following rules apply to
    nested user namespaces.

    1.  If a process has a capability in a user namespace has that
        capability in all descendant user namespaces as well.

    2.  The user that creates a user namespace while in the parent
        namespace has all capabilities in the created namespace
        and in all descendent user namespaces.

    So having said that part of my problem with your original
    text is that it actually switches directions.  One one rule
    it is looking into the descendent user namespaces, and in the
    other rule it is looking at ancestor user namespaces.

    So perhaps the text should read:

    With respect to capabilities, the following rules are used to
    answer the question does a process P have a capability C in a
    user namespace U.

    1. P has the capability C if P is in user namespace U and
       capability C is in process P's capability set.

    2. P has the capability C if P is in the parent of user
       namespace U and the euid of P is the euid that created user
       namespace U.

    3. P has the capability C if P has the capability C in some
       user namespace V that is an ancestor of U.

    Which probably gets a little extra mathematical, but it is
    precise.
