Richard Guy Briggs 3a10df7315 audit: log AUDIT_TIME_* records only from rules
[ Upstream commit 272ceeaea355214b301530e262a0df8600bfca95 ]

AUDIT_TIME_* events are generated when there are syscall rules present
that are not related to time keeping.  This will produce noisy log
entries that could flood the logs and hide events we really care about.

Rather than immediately produce the AUDIT_TIME_* records, store the data
in the context and log it at syscall exit time respecting the filter
rules.

Note: This eats the audit_buffer, unlike any others in show_special().

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.
