Hi, Do we currently expect the audit system to work with x32 syscalls? I was playing with the audit system for the first time today (on v4.0-rc2, due to [1]), and it didn't seem to work for me. (Tweaking ptrace.c like the patch below seemed to help, but I may just have configured something wrong.) I know there was a bunch of activity around this area in mid-2014, but I'm not sure what the final position was... Thanks, David [1]: https://lkml.org/lkml/2015/3/4/879 diff --git a/arch/x86/kernel/ptrace.c b/arch/x86/kernel/ptrace.c index e510618b2e91..443932afd9e8 100644 --- a/arch/x86/kernel/ptrace.c +++ b/arch/x86/kernel/ptrace.c @@ -1445,7 +1445,7 @@ static void do_audit_syscall_entry(struct pt_regs *regs, u32 arch) { #ifdef CONFIG_X86_64 if (arch == AUDIT_ARCH_X86_64) { - audit_syscall_entry(regs->orig_ax, regs->di, + audit_syscall_entry(regs->orig_ax & __SYSCALL_MASK, regs->di, regs->si, regs->dx, regs->r10); } else #endif
