commit483ec26eedupstream. Keep the ima policy rules around from the beginning even if they appear invalid at the time of loading, as they may become active after an lsm policy load. However, loading a custom IMA policy with unknown LSM labels is only safe after we have transitioned from the "built-in" policy rules to a custom IMA policy. Patch also fixes the rule re-use during the lsm policy reload and makes some prints a bit more human readable. Changelog: v4: - Do not allow the initial policy load refer to non-existing lsm rules. v3: - Fix too wide policy rule matching for non-initialized LSMs v2: - Fix log prints Fixes:b169424551("ima: use the lsm policy update notifier") Cc: Casey Schaufler <casey@schaufler-ca.com> Reported-by: Mimi Zohar <zohar@linux.ibm.com> Signed-off-by: Janne Karhunen <janne.karhunen@gmail.com> Signed-off-by: Konsta Karsisto <konsta.karsisto@gmail.com> Signed-off-by: Mimi Zohar <zohar@linux.ibm.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
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.
