From b23980e4f6ed33d98f4f09ef25ae17baca215cce Mon Sep 17 00:00:00 2001 From: Jerome Marchand Date: Thu, 11 Jun 2020 14:56:36 +0200 Subject: [PATCH 6/6] RHEL: aarch64: fixes statsnoop and opensnoop On aarch64 the open syscall has been dropped. Only openat remains, wich is called by libc open() function. The state of *stat* syscalls, is a mess. They are several generations of the system calls, and not all arches provides all of them. For instance, new(l)stat are missing from aarch64. The only way I can think of fixing thess is RHEL-8 only arch specific patches.
