Bug#982250: Forking on MMSD

Ofono maintainers are normally pretty responsive, and yes, you seem to
be cc-ing the right list.

I don't think forking ofono is good idea.

So with "reboot" mode, hibernation works as expected, you just have to
power down machine manually?

You may want to try without thunderbolt support / talk to thunderbolt
people:

pciehp seems to have bad problems, too.

I'd suggest debugging with s2ram (as it is less tricky) and removing
all modules you don't really need.

Good luck,
Pavel

You may want to add some printks to see where it hangs.

But maybe before that, you may want to test CPU hotplug, and make sure
s2ram works, etc...

Perhaps basic-pm-debugging.txt is good place to start?

Ok, I've just tested linux-next, and it works ok for me on thinkpad
x60. (But that's probably rather different configuration from the
macbook).

Unfortunately, I could not deduce anything useful from the
backtraces. Andrew, could you try v4.15 with KPTI disabled ?

Aha, good. I assume x86-64? Do you have kpti enabled?

Well, testing -rc1 once in 3 months should be plenty enough...

So hibernation is broken on x86-64?

Ideas for debugging:

1) get that sysrq to work, backtrace where it is hung would be very
useful.

2) try v4.15.

3) try without KPTI enabled. Probably noone knows how it interacts
with that...

(And 4), we should really start doing some periodic testing of hibernation).

Bug#767362: joystick: fftest loops when its stdin is closed

[Pavel Machek]

Source: joystick
Version: 1:1.4.3-1
Severity: normal

Dear Maintainer,

fftest enters loop when attempting to control it from pipe:

root@n900:~# echo 5 | fftest /dev/input/event2
Enter effect number, -1 to exit
Now Playing: Weak Rumble
Enter effect number, -1 to exit
Now Playing: Weak Rumble
Enter effect number, -1 to exit
Now Playing: Weak Rumble
...

Expected behaviour would probably be to exit when EOF is reached on
stdin.

 Please, Paul, take *yes* for an answer.  It is broken.  You've received
 multiple dissertations on why it is going to stay that way.  Unless you
 fix it yourself, and everyone seems to be politely wishing you the best
 of luck with that.

It is not Paul's job to fix PAE. It is job of whoever broke it to do
so.

If it is broken with 2GB of RAM, it is clearly not the known lowmem
starvation issue, it is something else... and probably worth
debugging.

So, Paul, if you have time and interest... Try to find some old kernel
version where sleep test works with PAE. Hopefully there is one. Then
do bisection... author of the patch should then fix it. (And if not,
at least you have patch you can revert.)

rjw is worth cc-ing at that point.

Bug#695182: [RFC] Reproducible OOM with just a few sleeps

[Pavel Machek]

Hi!

  I understand that more RAM leaves less lowmem. What is unacceptable is
  that PAE crashes or freezes with OOM: it should gracefully handle the
  issue. Noting that (for a machine with 4GB or under) PAE fails where the
  HIGHMEM4G kernel succeeds and survives.
 
 You have found a delta, but you're not really making apples-to-apples
 comparisons.  The page tables (a huge consumer of lowmem in your bug
 reports) have much more overhead on a PAE kernel.  A process with a
 single page faulted in with PAE will take at least 4 pagetable pages
 (it's 7 in practice for me with sleeps).  It's 2 pages minimum (and in
 practice with sleeps) on HIGHMEM4G.
 
 There's probably a bug here.  But, it's incredibly unlikely to be seen
 in practice on anything resembling a modern system.  The 'sleep' issue
 is easily worked around by upgrading to a 64-bit kernel, or using

Are you saying that HIGHMEM configuration with 4GB ram is not expected
to work?

 Thanks for the data and no, I cannot reproduce a crash on my main
 system (not debian). I get valgrind to complain about overlapping
 memcpy in the ALSA library, but that's not new and not specific to the
 file.

It does crash even if I just let it decode into a file. So that should
not be alsa.

 I checked a i686 chroot, too, no issue. I guess I'd need to whip out a debian
 install/vm to reproduce. I have intentionally very old glibc here;
 before that infamous memcpy optimization ... which we very well might
 be dealing with here. But a test LD_PRELOAD checking for overlapping
 memcpy didn't trigger, neither.

What is the infamous memcpy optimization? I tried brief google, but
nothing. This? http://lwn.net/Articles/417881/ It has no details :-(.

 Can you run under valgrind to check memory issues?

Hopefully I got valgrind right...

Bug#689187: python-gps: fakegps segfaults on NMEA file

[Pavel Machek]

Hi!

  fakegps segfaults on many nmea logs I could find. It does so even
  without all the debugging options.
 
 please provide the nmea files.

The file I can reproduce it is rather big (7MB). I tried shorter
sections, but no luck. I can send it to you, but would prefer it not
be redistributed; would that be feasible?

 Also please checkout the gpsd git repository or use apt-get to retrieve the
 source and check if they files from the regression tests fail on your 
 machine, too.
 
 In case they also fail...
 
  Kernel: Linux 3.6.0-rc6+ (SMP w/2 CPU cores)
 
 please try the same with a kernel shipped with Debian and

Sorry, that is not easy to do.

  Locale: LANG=C, LC_CTYPE=cs_CZ (charmap=)
 
 please also try it with en_US.UTF-8 or C as LC_TYPE.

Does not seem to help.

Bug#534731: stardict broadcasts clipboard context over network

[Pavel Machek]

Package: stardict
Version: 3.0.1-4.1
Severity: grave
Tags: security
Justification: user security hole


In default config enable net dict is selected, it attempts to grab
clipboard and sends it over network... Unfortunately, not nearly all
data in clipboard are meant for translation, and some may be pretty
sensitive.

Bug#507875: nbd-server: confusing man page

[Pavel Machek]

Package: nbd-server
Version: 1:2.9.11-1
Severity: normal

Man page for nbd-server is confusing:

-l host list is mentioned in 'SYNOPSIS'

down below, host list is mentioned without '-l', and it tells me that
host list   is not a list but a filename.

Perhaps 'host list' should be replaced with 'host list file' ?

Bug#383852: [Suspend-devel] Fw: Does not properly resume from S3 with kernel 2.6.17

[Pavel Machek]

Hi!

  Christian can't get s2ram to work to work with a 2.6.17 kernel, although
  it is in the whitelist. It used to work with 2.6.16. Do you now of any
  regressions? 
  Could anybody give him a hand in trying to get it to work again?
  
  In the mean time I asked him to try with minimal number modules loaded.
 
 I indeed tryied with way much less modules lodaded, without success:

Well, you still have way too many modules. What about init=/bin/bash
boot?

   I indeed tryied with way much less modules lodaded, without success:
  
  Well, you still have way too many modules. What about init=/bin/bash

 Well, with this, the system does not wake up either.
 
 Moreover, it *also* does not wake up properly when I boot with the
 2.6.16 kernel.
 
 Indeed, when the suspend to RAM happens while the machine is in text
 mode, the system usually does not wake up properly, either with 2.6.16
  or 2.6.17
 
 The wake up works well when initiated in graphics mode with the 2.6.16
 kernel.

Okay, can we get report at bugzilla.kernel.org (with all the
details, cc me and rafael)? I'm getting lost...

No, I do not know what the difference between .16 and .17 is... and we
may need to do git bisect after all..

 I'm not an idiot, so drivers for IDE (/dev/hda is IDE), ext2, and ext3 are 
 built-in.

Great. Find out what is wrong and report it to proper bugzilla,
then. That's likely *kernel* bugzilla, not Debian bugzilla for
self-compiled kernel.

Bug#305412: p2c segfaults on specific input

[Pavel Machek]

Package: p2c
Severity: grave
Tags: security
Justification: user security hole


I'm not really sure if this can be exploited, but I'm getting
segfaults while trying to convert specific program... It is small
enough to inline:

When p2c is run on program above, it ends with

#undef wz
#undef wy
#undef wx
#undef m


/*parametry elipsoidu WGS-84*/
