[PATCH 0/5] ftrace updates for tip

[Steven Rostedt]

Ingo,

Here's some more ftrace updates.

The first should help fix the bug in lockdep.

The next are changes to the ring buffer to get ready to have it
work with splice.

The last are some clean ups for function graph.


The following patches are in:

  git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-2.6-trace.git

    branch: tip/devel


Steven Rostedt (5):
      ftrace: replace raw_local_irq_save with local_irq_save
      ring-buffer: move some metadata into buffer page
      ring-buffer: read page interface
      ftrace: clean up function graph asm
      ftrace: have function graph use mcount caller address

[PATCH 0/5] ftrace: updates for tip

[Steven Rostedt]

Ingo,

Most of thes patches are improvements to function graph. I'm
working on making a way to pick a function to trace, which the
patch function entry patch is needed.

The one ring buffer patch converts all variables called 'page' to
'bpage' as per Andrew's request.

The following patches are in:

  git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-2.6-trace.git

    branch: tip/devel


Steven Rostedt (5):
      ftrace: add ftrace_graph_stop
      ring-buffer: change page variables to bpage
      ftrace: print real return in dumpstack for function graph
      ftrace: function graph return for function entry
      ftrace: add checks on ret stack in function graph

[PATCH 1/5] ftrace: add ftrace_graph_stop

[Steven Rostedt]

[-- Attachment #1: 0001-ftrace-add-ftrace_graph_stop.patch --]
[-- Type: text/plain, Size: 2425 bytes --]

From: Steven Rostedt <srostedt@redhat.com>

Impact: new ftrace_graph_stop function

While developing more features of function graph, I hit a bug that
caused the WARN_ON to trigger in the prepare_ftrace_return function.
Well, it was hard for me to find out that was happening because the
bug would not print, it would just cause a hard lockup or reboot.
The reason is that it is not safe to call printk from this function.

Looking further, I also found that it calls unregister_ftrace_graph,
which grabs a mutex and calls kstop machine. This would definitely
lock the box up if it were to trigger.

This patch adds a fast and safe ftrace_graph_stop() which will
stop the function tracer. Then it is safe to call the WARN ON.

[PATCH 2/5] ring-buffer: change page variables to bpage

[Steven Rostedt]

[-- Attachment #1: 0002-ring-buffer-change-page-variables-to-bpage.patch --]
[-- Type: text/plain, Size: 11097 bytes --]

From: Steven Rostedt <srostedt@redhat.com>

Impact: clean up

Andrew Morton pointed out that the kernel convention of a variable
named page should be of type page struct. The ring buffer uses
a variable named page for a pointer to something else. This patch converts
those to be called bpage.

[PATCH 3/5] ftrace: print real return in dumpstack for function graph

[Steven Rostedt]

[-- Attachment #1: 0003-ftrace-print-real-return-in-dumpstack-for-function.patch --]
[-- Type: text/plain, Size: 5848 bytes --]

From: Steven Rostedt <srostedt@redhat.com>

Impact: better dumpstack output

I noticed in my crash dumps and even in the stack tracer that a
lot of functions listed in the stack trace are simply
return_to_handler which is ftrace graphs way to insert its own
call into the return of a function. But we lose out where
the actually function was called from.

This patch adds in hooks to the dumpstack mechanism that detects
this and finds the real function to print. Both are printed to
let the user know that a hook is still in place.

This does give a funny side effect in the stack tracer output:

        Depth   Size      Location    (80 entries)
        -----   ----      --------
  0)     4144      48   save_stack_trace+0x2f/0x4d
  1)     4096     128   ftrace_call+0x5/0x2b
  2)     3968      16   mempool_alloc_slab+0x16/0x18
  3)     3952     384   return_to_handler+0x0/0x73
  4)     3568    -240   stack_trace_call+0x11d/0x209
  5)     3808     144   return_to_handler+0x0/0x73
  6)     3664    -128   mempool_alloc+0x4d/0xfe
  7)     3792     128   return_to_handler+0x0/0x73
  8)     3664     -32   scsi_sg_alloc+0x48/0x4a [scsi_mod]

As you can see, the real functions are now negative. This is due
to them not being found inside the stack.

[PATCH 4/5] ftrace: function graph return for function entry

[Steven Rostedt]

[-- Attachment #1: 0004-ftrace-function-graph-return-for-function-entry.patch --]
[-- Type: text/plain, Size: 5332 bytes --]

From: Steven Rostedt <srostedt@redhat.com>

Impact: feature, let entry function decide to trace or not

This patch lets the graph tracer entry function decide if the tracing
should be done at the end as well. This requires all function graph
entry functions return 1 if it should trace, or 0 if the return should
not be traced.

[PATCH 5/5] ftrace: add checks on ret stack in function graph

[Steven Rostedt]

[-- Attachment #1: 0005-ftrace-add-checks-on-ret-stack-in-function-graph.patch --]
[-- Type: text/plain, Size: 1498 bytes --]

From: Steven Rostedt <srostedt@redhat.com>

Import: robustness checks

Add more checks in the function graph code to detect errors and
perhaps print out better information if a bug happens.

hm, that's in the hotpath. What's the point of this? Do we want some sort 
of configuration vector that allows per function graphing versus 
entry-only traces?

Steve,

after your stream of ftrace patches i'm now getting easy crashes in the 
function-graph tracer - these crashes didnt occur before. See below an 
example. Config attached, kernel is tip/master.

Yeah, I can fix that up. This is a side effect of the change, the funny 
output is a stack trace fix. It did not handle not finding the function in 
the stack very well. It's not a dangling pointer or anything. It is just 
a hickup in the calculation:

Notice that 3568 + 240 = 3808

But how about I make it this:

> >   4)     3808      -1   stack_trace_call+0x11d/0x209

The -1 will be a way to flag that it was not found in the stack.

Actually, I'm fine with taking it out. But when we register a function 
graph, we register both a entry and exit. I would think it should still 
work if one was still set as the default. Unless we document it someplace 
that either the entry or exit must be set.

This change has the function graph work if one or the other is set to 
something other than the default.

Also, this is only in the static ftrace path, not dynamic, but then again, 
maybe that means it is even hotter.

I'm fine with pulling this out. It was not really needed, I was just 
trying to make it intuitive.

Hmm, I've actually had it the other way :-(  I hit this same crash without 
the patches, and it went away after adding my patches.

This is probably some nasty race that depends on a set of timings :-(

Cool! The output of the stack worked! My backtraces looked more like this, 
because it happened without the patches:

  [<ffffffff8020c0fd>] return_to_handler+0x0/0x73   
  [<ffffffff8020c132>] ? return_to_handler+0x35/0x73
  [<ffffffff8020c0fd>] return_to_handler+0x0/0x73
  [<ffffffff8020c0fd>] return_to_handler+0x0/0x73
  [<ffffffff8020c0fd>] return_to_handler+0x0/0x73
  [<ffffffff8020c0fd>] return_to_handler+0x0/0x73

I'll look into it.

I like it that way too. One should choose wether setting a callback on
entry or return or both.
But it makes sense for me that should work with only one...

...unless. Actually setting only a callback on entry shoud better been
done from the ftrace-function-tracer.

I've never had such a thing (didn't tested yet with the last Steven's
patches). But I had a strange
warn_on_slowpath at the middle of a reboot which seems to rely on the
function-graph-tracer, or perhaps ring-buffer,
both where cited in the trace. But my stacktraces were dirty. It
should be more understandable with the Steven latest patches
which fix the nasty stacktraces....

I will test all of that this evening.

Note, I've only seen this bug when I had stack tracer running as well. And 
according to Ingo's config, he has it turned on too. Could you test with 
CONFIG_STACK_TRACER as well.

[PATCH 0/5] ftrace: updates for tip

[Steven Rostedt]

Ingo,

These patches are fixes for the wakeup tracer.

The first is a fix to the empty output you reported to me earlier.

The second is a fix for the ring buffer to not record updates
if it is disabled, otherwised you can get empty traces there too.

The third is the wakeup change to record all tasks and not just
realtime tasks. It adds a wakeup_rt tracer to record only rt tasks.

The forth is the addition of the scheduling wakeup and sched switch
output to the wakeup tracer. This is very helpful data.

The last is probably the most important, and should go into 29 as well.
I never reset the timestamps used to connect the trace stamps in
the buffers. This can cause stale stamps to appear and explains
some of the really bad timestamps in the buffer I've seen.

-- Steve


The following patches are in:

  git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-2.6-trace.git

    branch: tip/devel


Steven Rostedt (5):
      trace: do not disable wake up tracer on output of trace
      ring-buffer: do not swap if recording is disabled
      trace: separate out rt tasks from wakeup tracer
      wakeup-tracer: show scheduling data in output
      ring-buffer: reset timestamps when ring buffer is reset

okay, i've pulled your fixes into tip/tracing/ftrace and i've cherry-picked 
the timestamp fix over into tracing/urgent.

Thanks,
