Christian Brauner 72c7fa7466 seccomp: avoid overflow in implicit constant conversion
commit 223e660bc7638d126a0e4fbace4f33f2895788c4 upstream.

USER_NOTIF_MAGIC is assigned to int variables in this test so set it to INT_MAX
to avoid warnings:

seccomp_bpf.c: In function ‘user_notification_continue’:
seccomp_bpf.c:3088:26: warning: overflow in implicit constant conversion [-Woverflow]
 #define USER_NOTIF_MAGIC 116983961184613L
                          ^
seccomp_bpf.c:3572:15: note: in expansion of macro ‘USER_NOTIF_MAGIC’
  resp.error = USER_NOTIF_MAGIC;
               ^~~~~~~~~~~~~~~~

README

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.
