Re: [Bug 1419436] Re: tls_socket_read (Decryption has failed.)

2015-03-12 Thread Donn Morrison
After recompiling mutt with openssl instead of gnutls I discovered that
openssl was also affected, so I tried another USB ethernet dongle and
that seems to have fixed it. At least I can't reproduce the problem with
the large IMAP fetch using openssl s_client. I've now blacklisted the
module for the onboard ethernet phy_twl4030_usb.

Maybe this bug could be reassigned?

2015-02-10 Thread Donn Morrison
Yes, I realise that now. I've tried on a Raspberry Pi with 2.12.20 (armhf)
without problems. What is curious is why it was working before under Ubuntu
12.04. Comparing tag and tag_ptr, I can say that it is in fact the HMAC that
differs, and not the padding check. I'll keep debugging.

[Bug 1419436] [NEW] tls_socket_read (Decryption has failed.)

2015-02-08 Thread Donn Morrison
Public bug reported:

Since moving from Ubunutu 12.04 (armel) to 14.04 (armhf) on a
Beagleboard I have a persistent problem using mutt where (especially)
larger messages fail to download resulting in the error:

tls_socket_read (Decryption has failed.)

The failure is reproducable in that I can almost never download messages
with attachments larger than 10MB (it will inevitably fail at some point
during the transfer).

12.04 (armel) had gnutls26 verison 2.12.14-5ubuntu3.8, and I never had
this problem. 14.04 uses 2.12.23-12ubuntu2.1. Strangely enough my amd64
machines which also run 14.04 and 2.12.23-12ubuntu2.1 do not have this
problem.

In attempting to debug I tried setting GNUTLS_DEBUG_LEVEL=6, which
didn't produce any output from libgnutls26. Next I tried forcing mutt to
use libgnutls28 (3.2.11-2ubuntu1) with LD_PRELOAD. Then setting
GNUTLS_DEBUG_LEVEL=6 and redirecting stderr to a file yields the
following log:

...

So this problem (at least on armhf) seems to affect both gnutls26 and

[Bug 1419436] Re: tls_socket_read (Decryption has failed.)

2015-02-08 Thread Donn Morrison
I dug a little deeper and recompiled gnutls28-3.2.11 from sources
provided by apt-get source and commented out the block at
gnutls_cipher.c:951(see snippet below) which caused the first assertion
in the log above. This fixes the problem, that is, I can download
attachments in mutt seemingly without problem.

My question now is, what are the implications of removing this check?
Any idea why this is only happening on armhf?

/* Here there could be a timing leakage in CBC ciphersuites that
 * could be exploited if the cost of a successful memcmp is high. 
 * A constant time memcmp would help there, but it is not easy to maintain
 * against compiler optimizations. Currently we rely on the fact that
 * a memcmp comparison is negligible over the crypto operations.
 */
//  if (unlikely
if (0  unlikely
(memcmp(tag, tag_ptr, tag_size) != 0 || pad_failed != 0)) {
/* HMAC was not the same. */
dummy_wait(params, compressed, pad_failed, pad,
   length + preamble_size);

return gnutls_assert_val(GNUTLS_E_DECRYPTION_FAILED);

l cleared up the reason for case #2 above. This is due to the Intel
Rapid Start Technology (IRST) in BIOS. When in sleep mode for a long

[Bug 1239990] [NEW] Selecting primary monitor is not intuitive

2013-10-15 Thread Donn Morrison
Public bug reported:

Today when I plugged in my external monitor the Activities bar/clock/etc
(is there a name for this?) was on the wrong screen. It took me 20
minutes of plugging/unplugging, restarting X, searching and reading
forums until I came across this AskUbuntu post [1]. The answer, to drag
the black bar to the other display in Settings  Displays, had been
sitting in front of my eyes all along, but apparently unless you've used
a Mac (I haven't) it is unreasonable to assume a user would know to do
this.

Granted, there is a tooltip that says Drag to change the primary
display. but this is only activated once you have already clicked on
the tiny black bar.

Perhaps a better UI hint would be useful here to say Hey, dumbass, drag
that very tiny black bar or something.

[Bug 1238914] [NEW] Random stuck keys on Lenovo Yoga 13

2013-10-11 Thread Donn Morrison
Public bug reported:

Certain keyboard keys get stuck down seemingly randomly resulting in
spurious bursts of key repeats. I have mostly noticed this with the
arrow keys, PgUp, PgDn and Delete. I have tried to replicate the
behaviour in the console with no luck so I believe this to be specific
to xserver. Using xev to debug a bit I can see that upon releasing the
key no keyup event is received. The key is not physically stuck.
Pressing any key on the keyboard interrupts the keydown repeats.

The common scenario is either browsing photos with eog or slides with
evince. This can cause data loss because if the move to trash
confirmation is disabled in eog you may delete many images without even
noticing. A minor annoyance when presenting slides because you suddenly
end up at the last slide in the deck, midway through your talk.

[Bug 1239004] [NEW] Cannot enter full disk encryption passphrase on Lenovo Helix in tablet mode

2013-10-11 Thread Donn Morrison
Public bug reported:

Fresh install of 13.10, selected full disk encryption.

The Lenovo Helix turns into a tablet by detaching from the keyboard. If
the system is rebooted while you are away from the keyboard (e.g., you
leave it at home) you cannot enter the passphrase. I suspect this is or
will become a problem for other tablets. I could not find any
information about a workaround through searching except for storing a
key on a USB stick and modifying initrd to read this at boot.

Obviously implementing an onscreen keyboard for the console at boot
seems a bit far fetched. Is there any idea for a workaround?

[Bug 1216558] Re: [LENOVO 36986CG] suspend/resume failure

2013-10-10 Thread Donn Morrison
I am having suspend/resume failures as well with kernel version 3.11.
There appears to be two aspects:

1. Keyboard does not work after resume (seemingly random). Reboot
required.

2. Suspend does not really suspend, PC remains on and eventually runs
out of battery (also random).

From my experience, the longer I let it sleep the higher the probability
of one of the two (above) happening. For #2, perhaps something is
causing the machine to wake up? I am pretty certain nothing touches it
and the power button is hard to press even when you really try.

[Bug 353812] Re: Multiple ATA Exception Emask, NCQ disabled etc during boot

2010-04-14 Thread Donn Morrison
Hi, I am having this issue on an Acer Aspire 1810TZ with a fresh 10.04
install (kernel version 2.6.32-19-generic #28-Ubuntu). Boot is very slow
and dmesg shows it is stuck after mounting the root partition with
messages as described in the original report.

I resolved the problem by changing from AHCI to IDE in the laptop's
BIOS.

[Bug 121123] Re: maximize/unmaximize doesn't restore window size

2008-03-11 Thread Donn Morrison

I can confirm this bug on metacity 2.20.0 (Ubuntu Gutsy) on a Lenovo T61
Thinkpad.

I've attached the metacity log as requested. It is quite long (~10MB
uncompressed), but I stopped it just after I was able to reproduce the
bug. In my case, this happens mostly in Firefox and Thunderbird,
although I've noticed it with other applications as well. I have a
keyboard shortcut mapped to toggle the maximization state of a window,
which I use frequently. I've tried to reproduce it but can never get it
to happen except by chance.

I must add that it is rather annoying.

Please re-open this bug.

Thank you,
Donn

[Bug 118747] Re: [gutsy] VTs unusable

2007-06-13 Thread Donn Morrison

Hi,

I'm also experiencing this problem. It can be worked around by
restarting udev. The CPU consumption drops and VTs are usable. It's a
bit of a pain to do this for each restart, however.
