commitb4d8a58f8dupstream. The desired behavior is to set the caller's filter count to thread's. This value is reported via /proc, so this fixes the inaccurate count exposed to userspace; it is not used for reference counting, etc. Signed-off-by: Hsuan-Chi Kuo <hsuanchikuo@gmail.com> Link: https://lore.kernel.org/r/20210304233708.420597-1-hsuanchikuo@gmail.com Co-developed-by: Wiktor Garbacz <wiktorg@google.com> Signed-off-by: Wiktor Garbacz <wiktorg@google.com> Link: https://lore.kernel.org/lkml/20210810125158.329849-1-wiktorg@google.com Signed-off-by: Kees Cook <keescook@chromium.org> Cc: stable@vger.kernel.org Fixes:c818c03b66("seccomp: Report number of loaded filters in /proc/$pid/status") 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.
