[ Upstream commit d57378d3aa4d864d9e590482602068af1b20c0c5 ] Currently ima_lsm_copy_rule() set the arg_p field of the source rule to NULL, so that the source rule could be freed afterward. It does not make sense for this behavior to be inside a "copy" function. So move it outside and let the caller handle this field. ima_lsm_copy_rule() now produce a shallow copy of the original entry including args_p field. Meaning only the lsm.rule and the rule itself should be freed for the original rule. Thus, instead of calling ima_lsm_free_rule() which frees lsm.rule as well as args_p field, free the lsm.rule directly.

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.
