Displaying the mode as part of the seectx takes up unnecessary memory, makes it so we can't use refcounted secctx so we need to alloc/free on every conversion from secid to secctx and introduces a space that could be potentially mishandled by tooling. Eg. In an audit record we get subj_type=firefix (enforce) Having the mode reported is not necessary, and might even be confusing eg. when writing an audit rule to match the above record field you would use -F subj_type=firefox ie. the mode is not included. AppArmor provides ways to find the mode without reporting as part of the secctx. So disable this by default before its use is wide spread and we can't. For now we add a sysctl to control the behavior as we can't guarantee no one is using this.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
