2.6.28-rc5: Reported regressions from 2.6.27

2.6.28-rc5: Reported regressions from 2.6.27

[Rafael J. Wysocki]

[NOTES:
 (1) Due to some recent controversies, in future I will only use 'Handled-By'
     tags for people who actually submit a patch or provide substantial help to
     the reporter (like advising him which commits to revert etc.).
 (2) We have almost as many regressions with patches as unresolved ones and
     the majority of these patches have not been merged for over two weeks
     (for almost three weeks in many cases and for over a _month_ in one case).
     IMO, this is insane.]

This message contains a list of some regressions from 2.6.27, for which there
are no fixes in the mainline I know of.  If any of them have been fixed already,
please let me know.

If you know of any other unresolved regressions from 2.6.27, please let me know
either and I'll add them to the list.  Also, please let me know if any of the
entries below are invalid.

Each entry from the list will be sent additionally in an automatic reply to
this message with CCs to the people involved in reporting and handling the
issue.

Some of them are quite serious too - some stuff is basically unusable in
2.6.28rc due to the vmalloc bug.

Is there any reason why someone (Rafael ?) shouldn't simply submit all of
those patches that look sensible, are reported to fix regressions and
whose maintainer has not provided a reason to NOT apply them into the
tree ?

Steve, Ingo, did you get into an agreement on the patch?
What should I test?

I see -rc5 is out, but I didn't spot the fix in the changelog.

Ingo's solution was to have the ring_buffer_resize return success on NULL 
buffer being passed in. Although I agree that it should not crash when 
passed a NULL pointer, I feel that a NULL pointer should return a -1 
(failure). The caller of the code (one place in kernel/trace/trace.c) 
could simply check if the buffer was allocated, and if not, simply ignore 
it.

I agree with Ingo that my original solution was too much churn. But the 
simple if statement and "indent" change is what I feel to be the solution, 
not letting the ring buffer return success on NULL pointer.

There is for SCSI.  Our two bugzilla entries each have several patches
(one has two, the other has four).  The patches listed in the
regressions aren't necessarily going to be the ones applied (depending
on how the arguing and testing goes).

There are no ABI guarantees for the sysprof tracer at this point,
given that it is in debugfs and that there is no working userspace
code using it.

to avoid situations like this, it would be nice to print out the 
format string itself in the trace header, in printf format string 
style. That way if there's a trivial expansion in trace format, it can 
be detected (and even followed) by user-space - without some ugly 
version based API.

Continue to malfunction. More details on the bugzilla entry. But basically, I had:

- one complete lock on VC switching (not switching back, just pressing ctrl-alt-f1).
- 3 two-plus minutes delay on VC switching
- a complete freeze on resuming from ram (not even SysRq-b working).

OTOH, it seems that VC malfunctioning happens only with "visual effect" aka 
compiz on.

Back to 2.6.27.5. This is quite worrying now... should I try to start a
bisection? Although I know from experience that bisecting over a -rc1 is quite
painful.

At which point exactly does it hang?

What's the most recent kernel you tried?

Again, at which point does it hang exactly?

I assume this doesn't happen with 2.6.27.  Is this correct?

The patch works fine here. I applied it to 2.6.27.5 and resume works.

Thanks for testing, I'm going to push it upstream shortly.

It's not clear to me that sysprof userspace could realistically do
runtime detection. It would require (a) using sscanf() to parse the
output and (b) that only the types changed, not the actual content or
ordering. (a) is likely a non-starter performance-wise (the first
version actually did this and it was too slow), and (b) means there
are strict limits to what could be changed anyway.
