From: Kees Cook Date: Wed, 8 May 2024 17:13:41 +0000 (-0700) Subject: seccomp: Constify sysctl subhelpers X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e406737b11103752838cf50fd197ec8e9352bbf7;p=linux.git seccomp: Constify sysctl subhelpers The read_actions_logged() and write_actions_logged() helpers called by the sysctl proc handler seccomp_actions_logged_handler() are already expecting their sysctl table argument to be read-only. Actually mark the argument as const in preparation[1] for global constification of the sysctl tables.
