small question,
ptrace_notify() and forward calls are able to both indirectly and directly call schedule(),
/* direct call from ptrace_stop()*/,
should, in this case, rcu_user_enter() be called before tracehook_report_syscall_exit(regs, step)
and ptrace chain?

Well, I don't really understand this magic... but why?
Until we return to user-mode this CPU should be in "in_user = false" state.
I am not sure I understand how it is guaranteed that rcu_user_exit() was
called... probably TIF_NOHZ should trigger the slow path and ensure that
syscall_trace_enter()->rcu_user_exit() will be called.

My understanding is (I may be wrong) that we can schedule() from ptrace chain to
some arbitrary task, which will continue its execution from the point where RCU assumes
CPU as not idle, while CPU in fact still in idle state -- no one said rcu_idle_exit()
(or similar) prior to schedule() call.
if so, does the same apply to in_user?

Oh, I bet I have much more chances to be wrong ;)

I don't understand how ptrace chain differs from, say, audit_syscall_exit().
There is nothing special in ptrace_stop() in this respect.

Not sure we understand each other. But I believe that ->in_user should be
already false when syscall_trace_leave() is called.

Oh -- you quoted the Tiny RCU (CONFIG_SMP=n) variant of rcu_is_cpu_idle(),
so I just thought that you were reproducing on CONFIG_SMP=n. You would
have to actually rebuild the kernel to get the different version.
But never mind! RCU_USER_QS depends on CONFIG_SMP=y, so my question
was irrelevant.

Yeah but when we are in syscall_trace_leave(), the CPU shouldn't be in
RCU idle mode. That's where the bug is. How do you manage to trigger
this bug?

* [PATCH] rcu: Fix unrecovered RCU user mode in syscall_trace_leave()

On x86-64 syscall exit, 3 non exclusive events may happen
looping in the following order:
1) Check if we need resched for user preemption, if so call
schedule_user()
2) Check if we have pending signals, if so call do_notify_resume()
3) Check if we do syscall tracing, if so call syscall_trace_leave()
However syscall_trace_leave() has been written assuming it directly
follows the syscall and forget about the above possible 1st and 2nd
steps.
Now schedule_user() and do_notify_resume() exit in RCU user mode
because they have most chances to resume userspace immediately and
this avoids an rcu_user_enter() call in the syscall fast path.
So by the time we call syscall_trace_leave(), we may well be in RCU
user mode. To fix this up, simply call rcu_user_exit() in the beginning
of this function.
This fixes some reported RCU uses in extended quiescent state.

Thanks.
Sergey, Dave,
Does the patch I just sent you fix the issue?
Patch is "[PATCH] rcu: Fix unrecovered RCU user mode in syscall_trace_leave()"
Thanks.

I only saw this happening after hours of fuzzing.
Right now I keep running into other issues before that gets a chance to happen,
so I've not seen it in a while.
I'll apply it to my tree, and run with it though.
If I see it again, you'll be first to know :)
