From 16add411645cff83360086e102daa67b25f1e39a Mon Sep 17 00:00:00 2001 From: "Dmitry V. Levin" Date: Mon, 18 Mar 2019 02:30:18 +0300 Subject: syscall_get_arch: add "struct task_struct *" argument This argument is required to extend the generic ptrace API with PTRACE_GET_SYSCALL_INFO request: syscall_get_arch() is going to be called from ptrace_request() along with syscall_get_nr(), syscall_get_arguments(), syscall_get_error(), and syscall_get_return_value() functions with a tracee as their argument. The primary intent is that the triple (audit_arch, syscall_nr, arg1..arg6) should describe what system call is being called and what its arguments are.
