Subject: [PATCH 11/27] userns: Convert the audit loginuid to be a kuid
From: "Eric W. Biederman" <ebiederm@...ssion.com>
Always store audit loginuids in type kuid_t.
Print loginuids by converting them into uids in the appropriate user
namespace, and then printing the resulting uid.
Modify audit_get_loginuid to return a kuid_t.
Modify audit_set_loginuid to take a kuid_t.
Modify /proc/<pid>/loginuid on read to convert the loginuid into the
user namespace of the opener of the file.
Modify /proc/<pid>/loginud on write to convert the loginuid
rom the user namespace of the opener of the file.
