-Subject: [PATCH] ptrace: being capable wrt a process requires mapped uids/gids
-
-ptrace_has_cap() checks whether the current process should be
-treated as having a certain capability for ptrace checks
-against another process. Until now, this was equivalent to
-has_ns_capability(current, target_ns, CAP_SYS_PTRACE).
-
-However, if a root-owned process wants to enter a user
-namespace for some reason without knowing who owns it and
-therefore can't change to the namespace owner's uid and gid
-before entering, as soon as it has entered the namespace,
-the namespace owner can attach to it via ptrace and thereby
-gain access to its uid and gid.
-
-While it is possible for the entering process to switch to
-the uid of a claimed namespace owner before entering,
-causing the attempt to enter to fail if the claimed uid is
-wrong, this doesn't solve the problem of determining an
-appropriate gid.
-
-With this change, the entering process can first enter the
-namespace and then safely inspect the namespace's
-properties, e.g. through /proc/self/{uid_map,gid_map},
-assuming that the namespace owner doesn't have access to
-uid 0.
-
-Changed in v2: The caller needs to be capable in the
-namespace into which tcred's uids/gids can be mapped.
