From e198fdc9284fccf4fe01b0c7d92bab77984a8a2c Mon Sep 17 00:00:00 2001 From: Puranjay Mohan Date: Thu, 23 Feb 2023 09:53:46 +0000 Subject: [PATCH] libbpf: Fix arm syscall regs spec in bpf_tracing.h The syscall register definitions for ARM in bpf_tracing.h doesn't define the fifth parameter for the syscalls. Because of this some KPROBES based selftests fail to compile for ARM architecture. Define the fifth parameter that is passed in the R5 register (uregs[4]).
