From 24fe764c8a14bd519826e7e9af01edff59ab6be3 Mon Sep 17 00:00:00 2001 From: Hannes Domani Date: Tue, 7 Apr 2020 20:57:07 +0200 Subject: [PATCH] Add _sigsys info to siginfo struct This patch adds information about _sigsys structure from newer kernels, so that $_siginfo decoding can show information about _sigsys, making it easier for developers to debug seccomp failures.
