2016-04-04 Thread a1291762
I downloaded the Ubuntu 4.6.0 rc2 image (4.6.0-040600rc2-generic) and confirmed 
the issue remains (as with the last mainline build I tested, it does not show 
up as quickly, I guess something about the memory layout has changed).
I downloaded current linux HEAD source and verified the code still looks 
incorrect (it does).
I downloaded a pre-git Linux history repo (from the internet archive) and 
traced the bad code to commit ef1bba7ed87a4059ee725565689a1706e9f11534. The 
driver maintainer seems to be the same person, maybe they have some 
recollection that helps because the change itself does not enlighten me.

[Bug 1547838] Re: ADMtek ADM8511 "Pegasus II" USB Ethernet causes oops

2016-04-01 Thread a1291762
Another data point for consideration... (I didn't think of this until
late last night)

git checkout Ubuntu-3.10.0-0.6
git revert 313a58e487ab3eb80e7e1f9baddc75968288aad9
# resolve a header conflict - nothing major

After building this, I was able to use the network dongle just fine (ie.
second and third pegasus-related commits were ok, one of them even
removed that warning when inserting the device).

I had a look at the commit and it looks ok...

I'm guessing from the change in code that the "pool" was not necessary,
and that the extra skb buffer objects went unused most of the time.
However, I believe they hid a buffer overrun.

The skb buffer was previously allocated as PEGASUS_MTU + 2. The new
buffer is allocated as PEGASUS_MTU (with optional padding for alignment
purposes). From what I can see, this should make the usable buffer
consistently smaller than the old structure allowed for (by 2 bytes).

The real problem though, is that when reading into the skb buffer, the
driver uses PEGASUS_MTU + 8 as the buffer size, a pretty clear buffer
overrun to me. I don't know how the kernel is allocating this memory but
I guess the underlying allocation pattern of the "pool" code was able to
hide the effect of the overrun and this change merely exposed it by
changing the allocation pattern.

Indeed, the attached patch (which passes the correct buffer size to the
read function) also fixes things. I suppose this is the fix that should
be committed.

I guess this needs to go upstream to the kernel guys though?

[Bug 1547838] Re: ADMtek ADM8511 "Pegasus II" USB Ethernet causes oops

2016-04-01 Thread a1291762
The good news is that I have identified the commit that breaks my
system. It is 313a58e487ab3eb80e7e1f9baddc75968288aad9 (the first of 3
commits to the pegasus driver). I have attached the bisect log in case
it's interesting.

Here's some notes on my process...

The bisecting was entirely in commits that lacked the debian directories
so I used the patches from http://kernel.ubuntu.com/~kernel-
ppa/mainline/v3.9-saucy/ to restore them. Most of the time, the kernel
asked about configs that were new. I just accepted the defaults.

My build/run process went like this.

# remove old kernels
COLUMNS= dpkg -l | awk '/linux-image/{print $2}' | grep -v '3\.19' | grep -v 
lts | xargs sudo apt-get -y remove --purge
# backup old packages
mv ../*.deb ../old
# so the patch works
rm -rf debian*
# depending on the previous test
git bisect good/bad
# so I can build
for file in ../3.9/*.patch; do patch -p1 < $file; done
# set the version to something useful (3.9.0-0+lrx)
vi debian.master/changelog
chmod a+x debian/rules debian/scripts/* debian/scripts/misc/*
fakeroot debian/rules clean
fakeroot debian/rules binary-headers binary-generic
sudo dpkg -i ../linux-image-*
sudo reboot
# test by booting from the kernel, plugging in the USB dongle and pinging the 
gateway

2016-03-27 Thread a1291762
I have narrowed it further to these builds.

3.9.0-7.15 - good
3.10.0-0.6 - bad

I've managed to fetch the saucy repo. git says there's around 14,000
commits between these two tags?!

I'm going to first verify that when I build both of these tags I get the
same behaviour as I do with the binary builds. Then I'll start the git
bisect properly.

Unfortunately, as slow as my internet is, downloading kernels is quite a
bit faster than building them appears to be :(

[Bug 1547838] Re: ADMtek ADM8511 "Pegasus II" USB Ethernet causes oops

2016-03-26 Thread a1291762
Sigh. I was forgetting about the linux-image-extra package. This proved
to make a difference. Indeed, the post-Saucy versions that were
succeeding were only doing so because the image-extra package was
missing. Strangely, the USB dongle worked without that package but
clearly there's an interaction with something else that needs a module
from that package.

Armed with this new knowledge, I re-tested some of the builds I had
tested previously (now with image-extra) and found this.

3.9.0-0  - good*
3.11.0-26  - bad

These are the first and last kernels of Saucy. The first one does not
have an image-extra (the image package is larger). The last one does
have an image-extra. I guess some time during Saucy, the packaging was
changed?

My testing yesterday was booting with the USB dongle inserted (so that
networking config could be applied during boot, similarly to how I
intend to run the system). Today, I have been inserting the dongle after
the system boots. I have attached netconsole5.log, which shows the
kernel warning/error I got when I plugged the dongle in (on kernel
3.9.0-0). Note that despite this output, the system continued to run
just fine.

[Bug 1547838] Re: ADMtek ADM8511 "Pegasus II" USB Ethernet causes oops

2016-03-26 Thread a1291762
In the absence of a reply to my question, I tried downloading various
binary kernels to at least narrow down the scope of the bisecting I'll
have to do. After trying older releases and having no failures, I
unexpectedly found that 14.04 kernels only cover 3.11 to 3.13. But I'm
running 14.04 and I'm on kernel 3.19?! It seems the 14.04.x updates
include kernels from newer releases. So this bug is much more recent
than I originally anticipated. How recent? Vivid recent.

Kernel 3.19.0-7 is good.
Kernel 3.19.0-51 is bad.

That cuts way down on the search space. I might try some more binary
kernels in this range while I sort out how to do source builds (in case
there are more commits than binaries - which is what I'm expecting).

I think this means I'll be able to download
git://kernel.ubuntu.com/ubuntu/ubuntu-vivid.git to get the appropriate
tags to bisect from. I found a hint to use fetch --depth=1, then fetch
--depth=1000, etc. to incrementally fetch a large repo.

Am I supposed to be bisecting mainline kernel or the Ubuntu kernel?

That page seems a bit out of date, I'm guessing I should be cloning

I am somewhat bandwidth challenged at home. Is there a recommended way
to fetch this monstrosity over a low-bandwidth, low-reliability link?

2016-03-19 Thread Christopher M. Penalver
a1291762, the next step is to fully commit bisect from kernel 2.6.22 to
3.19 in order to identify the last good kernel commit, followed
immediately by the first bad one. This will allow for a more expedited
analysis of the root cause of your issue. Could you please do this
following https://wiki.ubuntu.com/Kernel/KernelBisection ?

Please note, finding adjacent kernel versions is not fully commit
bisecting.

After the offending commit (not kernel version) has been identified,
then please mark this report Status Confirmed.

Thank you for your understanding.

It is still broken in the mainline kernel.

The top entry at the URL was this:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.5-wily/

The package versions were:
Selecting previously unselected package linux-headers-4.5.0-040500-generic.
Selecting previously unselected package linux-headers-4.5.0-040500.
Selecting previously unselected package linux-image-4.5.0-040500-generic.

I selected the version explicitly from the grub menu to ensure the
correct kernel was booting.

I've attached netconsole4.log, which shows a crash plus a complete boot-
to-crash netconsole log with the 4.5.0 kernel.

[Bug 1547838] Re: ADMtek ADM8511 "Pegasus II" USB Ethernet causes oops

2016-03-13 Thread Christopher M. Penalver
a1291762, in order to allow additional upstream developers to examine the 
issue, at your earliest convenience, could you please test the latest upstream 
kernel available from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ? 
Please keep in mind the following:
1) The one to test is at the very top line at the top of the page (not the 
daily folder).
2) The release names are irrelevant.
3) The folder time stamps aren't indicative of when the kernel actually was 
released upstream.
4) Install instructions are available at 
https://wiki.ubuntu.com/Kernel/MainlineBuilds .

If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.

If the latest kernel did not allow you to test to the issue (ex. you couldn't 
boot into the OS) please make a comment in your report about this, and continue 
to test the next most recent kernel version until you can test to the issue. 
Once you've tested the upstream kernel, please comment on which kernel version 
specifically you tested. If this issue is fixed in the mainline kernel, please 
add the following tags by clicking on the yellow circle with a black pencil 
icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, and Y are the first two numbers of the kernel version, and Z is
the release candidate number if it exists.

If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of
kernel-bug-exists-upstream.

Also, you don't need to apport-collect further unless specifically
requested to do so.

Once testing of the latest upstream kernel is complete, please mark this
report Status Confirmed. Please let us know your results.

Thank you for your understanding.

I had to jump through some hoops to update the BIOS (since the updater
was a Windows binary and this machine does not have Windows on it). But
I finally sorted something out.

dmidecode output:
68PDV Ver. F.20
12/08/2011

The adapter seems to be stable now. I brought it up, did some pings,
even some file transfers. I have not seen even a hint of a problem yet.

The machine at work this adapter was causing problems with was also a HP
so maybe it too needed a BIOS update.

I am surprised, but thankful that it's working now.

Thanks.

http://h20564.www2.hp.com/hpsc/swd/public/readIndex?sp4ts.oid=3781730=8=4060
an update to your computer's buggy, insecure, and outdated BIOS is
available (F.20). If you update to this following
https://help.ubuntu.com/community/BIOSUpdate does it change anything?

For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful.

Also, you don't have to create a new bug report.

Once the BIOS is updated, if the problem is still reproducible:
1) Please provide the output of the following terminal command (not perform an 
apport-collect):
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
2) Please make a comment specifically advising on if there was an improvement 
or not.
3) Please mark this report Status Confirmed.

If it's not reproducible, please mark this as Invalid.

Thank you for your understanding.

It seems this is a known issue...
https://bugs.launchpad.net/ubuntu/+source/apport/+bug/997020

I have set w3m as the text-mode browser (it was already installed) and
run apport-collect. It wants to upload nearly 600K, quite a bit more
than the other command gave.

2016-03-07 Thread a1291762
apport information

** Tags added: apport-collected

** Description changed:

  This is a rather old USB ethernet adapter. It worked fine for me with
  older distributions (including Ubuntu 10.04). I noticed it causing
  problems after upgrading to 14.04 and stopped using it as a result
  (since I needed reliable USB ethernet for work). I was also not
  completely sure if it was this device causing the issue or interplay
  between this device and a number of other networking USB devices that
  were used at work.
  
  I'd like to use this ethernet adapter at home but the machine is running
  Ubuntu 14.04 and the issue persists.
  
  I have collected some information that might help. I'm happy to try more
  things to collect information if that will help.
  
  I'm running Ubuntu 14.04 server 64-bit. I just rebooted so I'm running
  the latest updates.
  
  I was told to run ubuntu-bug linux but I'm not sure how much useful
  stuff is included in that. I'm including the kernel log which has some
  bad stuff happening in it. Not sure if it got the system-freezing oops
  or just the errors leading up to that.
  
  It feels like a bug in the driver that corrupts memory because I see
  issues with network-related things (eg. a ping crashed, but the next
  ping didn't), leading to a full-system freeze.
  
  This machine has been happily running Ubuntu for a looong time (though
  it was only recently upgraded to Ubuntu 14.04, previously it had been
  running 10.04). I have not had stability issues with the machine but
  plugging in the USB Ethernet reliably makes it freeze within minutes.
  The symptoms also match what I saw on my machine at work.

a1291762, if it isn't terribly inconvenient, one could boot from a live
environment via http://cdimage.ubuntu.com/daily-live/current/ .

If it is, then one could engage

apport-collect requires a web browser. This machine is a server. It has
lynx or links or something but Ubuntu's website does not work with that
browser. How should I continue?

[Bug 1547838] Re: ADMtek ADM8511 "Pegasus II" USB Ethernet causes oops

2016-02-20 Thread a1291762
Note if I plug in the device but don't send traffic over it, the system
manages to remain running for longer. I brought the interface up with a
static IP and the system remained up for well over 5 minutes before it
died. I was monitoring ifconfig and it had around 30 Rx packets and 300
Tx packets. I'm not sure what caused that, since it was static and no
traffic should have been going out. With DHCP, pings, etc. going over
the interface it kills the machine much quicker (all the previous
crashes involved me sending data over the link, mostly just pings and
whatever DHCP sends).

The first bit of complaining on the last log didn't all make it to the
netconsole and unlike previous instances, stayed on the screen for a
while so I got a photo.

I think the first netconsole missed some data at the start (I got a
belated firewall warning) so here's a second capture that seems to start
earlier.

In case it wasn't clear, most of the time I've been booting the machine
and then inserting the USB device (so that I could be sure all the
logging was ready to go before the problem happened).

Hmm... I tried the crash kernel but it didn't seem to work. So I used
the netconsole to capture more data than could fit on the screen.
