From c50b4659e444b020657e01bdf769c965e5597cb0 Mon Sep 17 00:00:00 2001 From: Mickaël Salaün Date: Tue, 29 Dec 2015 21:35:47 +0100 Subject: um: Add seccomp support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This brings SECCOMP_MODE_STRICT and SECCOMP_MODE_FILTER support through prctl(2) and seccomp(2) to User-mode Linux for i386 and x86_64 subarchitectures. secure_computing() is called first in handle_syscall() so that the syscall emulation will be aborted quickly if matching a seccomp rule. This is inspired from Meredydd Luff's patch (https://gerrit.chromium.org/gerrit/21425).
