[PATCH 1/6] tracing/wakeup: move access to wakeup_cpu into spinlock

[Steven Rostedt]

[-- Attachment #1: 0001-tracing-wakeup-move-access-to-wakeup_cpu-into-spinl.patch --]
[-- Type: text/plain, Size: 1946 bytes --]

From: Steven Rostedt <srostedt@redhat.com>

The code had the following outside the lock:

        if (next != wakeup_task)
                return;

        pc = preempt_count();

        /* The task we are waiting for is waking up */
        data = wakeup_trace->data[wakeup_cpu];

On initialization, wakeup_task is NULL and wakeup_cpu -1. This code
is not under a lock. If wakeup_task is set on another CPU as that
task is waking up, we can see the wakeup_task before wakeup_cpu is
set. If we read wakeup_cpu while it is still -1 then we will have
a bad data pointer.

This patch moves the reading of wakeup_cpu within the protection of
the spinlock used to protect the writing of wakeup_cpu and wakeup_task.

[ Impact: remove possible race causing invalid pointer dereference ]

[PATCH 2/6] tracing: increase size of number of possible events

[Steven Rostedt]

[-- Attachment #1: 0002-tracing-increase-size-of-number-of-possible-events.patch --]
[-- Type: text/plain, Size: 2362 bytes --]

From: Steven Rostedt <srostedt@redhat.com>

With the new event tracing registration, we must increase the number
of events that can be registered. Currently the type field is only
one byte, which leaves us only 256 possible events.

Since we do not save the CPU number in the tracer anymore (it is determined
by the per cpu ring buffer that is used) we have an extra byte to use.

This patch increases the size of type from 1 byte (256 events) to
2 bytes (65,536 events).

It also adds a WARN_ON_ONCE if we exceed that limit.

[ Impact: allow more than 255 events ]

[PATCH 3/6] tracing: add size checks for exported ftrace internal structures

[Steven Rostedt]

[-- Attachment #1: 0003-tracing-add-size-checks-for-exported-ftrace-interna.patch --]
[-- Type: text/plain, Size: 1958 bytes --]

From: Steven Rostedt <srostedt@redhat.com>

The events exported by TRACE_EVENT are automated and are guaranteed
to be correct when used.

The internal ftrace structures on the other hand are more manually
exported. These require the ftrace maintainer to make sure they
are up to date.

This patch adds a size check to help flag when a type changes in
an internal ftrace data structure, and the update needs to be reflected
in the export.

If a export is incorrect, then the only harm is that the user space
tools will not know how to correctly read the internal structures of
ftrace.

[ Impact: help prevent inconsistent ftrace format print outs ]

[PATCH 5/6] tracing: fix cut and paste macro error

[Steven Rostedt]

[-- Attachment #1: 0005-tracing-fix-cut-and-paste-macro-error.patch --]
[-- Type: text/plain, Size: 2216 bytes --]

From: Steven Rostedt <srostedt@redhat.com>

In case a module uses the TRACE_EVENT macro for creating automated
events in ftrace, it may choose to use a different file name
than the defined system name, or choose to use a different path than
the default "include/trace/events" include path.

If this is done, then before including trace/define_trace.h the
header would define either "TRACE_INCLUDE_FILE" for the file
name or "TRACE_INCLUDE_PATH" for the include path.

If it does not define these, then the define_trace.h defines them
instead. If define trace defines them, then define_trace.h should
also undefine them before exiting. To do this a macro is used
to note this:

 #ifndef TRACE_INCLUDE_FILE
 # define TRACE_INCLUDE_FILE TRACE_SYSTEM
 # define UNDEF_TRACE_INCLUDE_FILE
 #endif

[...]

 #ifdef UNDEF_TRACE_INCLUDE_FILE
 # undef TRACE_INCLUDE_FILE
 # undef UNDEF_TRACE_INCLUDE_FILE
 #endif

The UNDEF_TRACE_INCLUDE_FILE acts as a CPP variable to know to undef
the TRACE_INCLUDE_FILE before leaving define_trace.h.

Unfortunately, due to cut and paste errors, the macros between
FILE and PATH got mixed up.

[ Impact: undef TRACE_INCLUDE_FILE and/or TRACE_INCLUDE_PATH when needed ]

[PATCH 6/6] ring_buffer: compressed event header

[Steven Rostedt]

[-- Attachment #1: 0006-ring_buffer-compressed-event-header.patch --]
[-- Type: text/plain, Size: 11120 bytes --]

From: Lai Jiangshan <laijs@cn.fujitsu.com>

RB_MAX_SMALL_DATA = 28bytes is too small for most tracers, it wastes
an 'u32' to save the actually length for events which data size > 28.

This fix uses compressed event header and enlarges RB_MAX_SMALL_DATA.

[ Impact: saves about 0%-12.5%(depends on tracer) memory in ring_buffer ]

WARN_ON_ONCE() may not be sufficient IMO:

We can reach 65536 this way (It took me 15 mins):

while (foo_bar.id < 65536) {
	insmod trace-events-sample.ko
	rmmod trace-events-sample.ko
}

Now next id will be 0! Then do this:

console 1:
 # cat /debug/tracing/trace_pipe

console 2:
while (1) {
	insmod trace-events-sample.ko
	echo foo_bar > /debug/tracing/set_event
	rmmod trace-events-sample.ko
}

I got this immediately:

This WARN_ON is triggered when we create an event with id == 65535,
but not 65536.

Hm, i think this might also call for a 32-bit event ID after all, 
right? Especially if we get some more dynamic form of injecting such 
tracepoints, 64K does not sound all that far in the future anymore. 
It is stretching things, but still it would be a silly limit to 
leave in place, hm?

Hm, the changelog is not valid anymore - as here we really cut it

Heh, that's what happens when I forward port a patch. I did not look at 
all the changes that had happened.

Grumble, this patch was also written before events could be in modules.
I need to change the way register events works to reuse events.

I could have it search the list of events on overflow to find a new 
number.

Or search for an available number and fail (and warn on) if it fails.

I would like to keep the size of the buffer down as much as possible. 
There are only 22,000 functions (with full function tracing) so 65000 
events should be more than enough.

The problem happens when we load and unload modules. If 65000 is not 
enough, 4G wont be enough either. We would only need to run the module 
load/unload a bit longer ;-)

I'll work on adding a way to reuse event keys.

the HEAD: 9ce5424d75e56891905b77d1589924765e62059a + this patch

(I commented out "hi" from the sample module)

I think it's because "type" is wrapped back to 0. I changed the test script
like this:

while (foo_bar.id < 65536)
{
	insmod trace-events-sample.ko
	rmmod trace-events-sample.ko
}

for ((; ;))
{
        insmod /home/lizf/linux-2.6-tip/samples/trace_events/*.ko
        echo trace-events-sample:foo_bar > /mnt/tracing/set_event
        sleep 1
        cat /mnt/tracing/trace
        rmmod /home/lizf/linux-2.6-tip/samples/trace_events/*.ko
}

See what I saw:

The bug won't be triggered with your latest changes, but it has nothing
to do with the debugfs patch, it's because this patch:
	"tracing/events: reuse trace event ids after overflow"

But that patch just hides the bug not fixes it.. I thought I explained
the bug clearly. :(

I think the bug is triggered because a wrong trace_event->trace() is called.


Before the above patch:
   id overflowed
 =>foo_bar.id == 6 == TRACE_BPRINT
 =>echo foo_bar > set_event
 =>sleep N secs
 =>rmmod sample
 =>cat trace
   =>trace_bprint_event->trace() is called!!
     =>oops!!!


After the above patch:

   Suppose id 0 ~ 65534 are used, only 65535 is left, and we have 2 different
   sample module trace_event subsystems foo and bar.
 =>insmod foo.ko, and foo.id == 65535
 =>echo foo > set_event
 =>sleep N secs
 =>rmmod foo.ko
 =>insmod bar.ko, and bar.id == 65535
 =>cat trace
   =>bar->trace() will be called on events which were generated by foo!

So is it possible/sane to discard corresponding events from ring buffer when
we unload a module?

Correct me if I'm wrong..

OK, I understand what you are saying.

You are saying that if we reuse the event id, then there is a case that 
the event can be used by another module, and if we have old data in the 
ring buffer the other module's callback will be called with the previous 
module's data.

Right?


A module should not be storing pointers into the ring buffer. We do 
that with the trace_print, but I think we were suppose to do something 
special if we detect that it is a module being called.

  Frederic?

If the module only stores data and never a pointer, then the worst thing 
stale data would do is show junk.

Scanning the ring buffer and discarding the module data can be very racy. 
We would need to disable the ring buffer while doing this. Probably the 
best thing to do is to simpy reset the ring buffers if it detects that a 
module is being unloaded and has callbacks. The data in the ring buffer is 
garbage anyway, so might as well reset it.

I agree, if no better way.

tracing: reset ring buffer when removing modules with events

Li Zefan found that there's a race using the event ids of events and
modules. When a module is loaded, an event id is incremented. We only
have 16 bits for event ids (65536) and there is a possible (but highly
unlikely) race that we could load and unload a module that registers
events so many times that the event id counter overflows.

When it overflows, it then restarts and goes looking for available
ids. An id is available if it was added by a module and released.

The race is if you have one module add an id, and then is removed.
Another module loaded can use that same event id. But if the old module
still had events in the ring buffer, the new module's call back would
get bogus data.  At best (and most likely) the output would just be
garbage. But if the module for some reason used pointers (not recommended)
then this could potentially crash.

The safest thing to do is just reset the ring buffer if a module that
registered events is removed.

[ Impact: prevent unpredictable results of event id overflows ]
