[Bug 1856492] Re: linux-generic-hwe-18.04=5.3.0.25.94 in bionic-proposed causes a conflict with virtualbox-guest-x11-hwe

2020-04-01 Thread Matthias Kruzenski
@Sultan Alsawaf

Thanks for the feedback, but it must be a dependency problem for the
following reasons:

1.) If I had a signed kernel, I could see it when I query the list of
installed packages with dpkg -l

2.) It worked until mid-December when Kernel 5.0.0 was available (Kernel
5.3.0 was only in bionic-proposed at that time)



Kernel 5.0.0:
=

root@ubuntu:~# dpkg -l | grep linux-image
ii  linux-image-5.0.0-31-generic   5.0.0-31.33~18.04.1  
i386 Linux kernel image for version 5.0.0 on 32 bit x86 SMP
ii  linux-image-generic-hwe-18.04  5.0.0.31.88  
i386 Generic Linux kernel image

apt-get install virtualbox virtualbox-guest-x11-hwe virtualbox-ext-pack
(no problems)



Kernel 5.3.0:
=

root@ubuntu:~# dpkg --list | grep linux-image
ii  linux-image-5.3.0-42-generic   5.3.0-42.34~18.04.1  
i386 Linux kernel image for version 5.3.0 on 32 bit x86 
SMP
ii  linux-image-generic-hwe-18.04  5.3.0.42.99  
i386 Generic Linux kernel image

apt-get install virtualbox virtualbox-guest-x11-hwe virtualbox-ext-pack
(kernel gets removed)



Someone screwed it up when creating the new packages and nobody is
fixing it... as usual...

Hi,

this bug still exists! It is IMPOSSIBLE to install linux-generic-
hwe-18.04 and virtualbox virtualbox-guest-x11-hwe virtualbox-ext-pack at

[Bug 1848940] Re: gnome-control-center does not respect symbolic links

2019-10-20 Thread Matthias Kruzenski
In short: Symbolic links are absolutely necessary to exclude files from
overlayfs.

Long explanation:
I use overlayfs to protect my system's root file system. With overlayfs all 
changes are only in RAM. So any change is only temporary.

I want some changes to be persistent. To do that I copy these files to
another partition and create a link. For example I want that my system
remembers any network connection so I move /etc/NetworkManager/system-
connections/ to another partition and create a link to it. The same
applies to the home directory or /var/lib/AccountsService/users/. This
will exclude these files from overlayfs.

This gives me a superfast system that allows me to do almost any
experiment. If something goes wrong I just restart it and it's the same
as before. Even more, it's almost impossible to infect this system with
malware. It also use full disk encryption (including /boot) and runs
from usb. It is a highly secure system...

I'm pretty sure there are many more use cases that require symbolic
links for config files.

[Bug 1848940] [NEW] gnome-control-center does not respect symbolic links

2019-10-20 Thread Matthias Kruzenski
Public bug reported:

Configuration files created as symbolic links are overwritten by gnome-
control-center. This probably affects any configuration file managed by
gnome-control-center.

Test case:
--

1.) Create symbolic links of the following files

sudo mv /etc/default/locale /etc/default/locale.test && sudo ln -s
/etc/default/locale.test /etc/default/locale

sudo mv /etc/default/keyboard /etc/default/keyboard.test && sudo ln -s
/etc/default/keyboard.test /etc/default/keyboard

sudo mv /etc/hostname /etc/hostname.test && sudo ln -s
/etc/hostname.test /etc/hostname

2.) Change the language, the keyboard layout and the hostname in gnome-
control-center.


Expected result:
The link destination should be overwritten so that the symbolic link is 
preserved.

Actual result:
The symbolic link itself is overwritten so that the symbolic link is lost.

[Bug 1621367] Re: 4.4.0-36: keyboard dead at boot & full disk encryption prompt for password

2019-10-03 Thread Matthias Kruzenski
A purely speculative assumption:

For some reason, Logitech hardware can immediately go into autosuspend
mode.

To prevent this, you can add the following kernel command line
parameter:

usbcore.autosuspend=-1

In addition, you should execute the following commands:

tee --append /etc/modprobe.d/usbcore.conf << EOF
options usbcore autosuspend=-1
EOF

update-initramfs -u -k all

Note: It depends on the kernel from where the configuration is read, so
it is best to add both the parameter and the config file.

It may also be helpful to use a different USB port.

[Bug 1842382] Re: /proc/self/maps paths missing on live session (was vlc won't start; eoan 19.10 ubuntu/lubuntu/kubuntu/xubuntu/ubuntu-mate daily)

2019-09-15 Thread Matthias Kruzenski
The reason why vlc does not start is definitely the overlay filesystem.

How can I know that?

I use Ubuntu on a fully encrypted USB stick with overlay root filesystem
(which makes the USB super fast, even faster than ssd).

To enable the overlay root filesystem I use the following initramfs script:
https://gist.github.com/niun/34c945d70753fc9e2cc7

(FYI: the script has a little bug, it can not handle tabulators in
fstab, you have to fix that if you want use it for testing, just insert
tr "\t" ' ' before grep -v ' / ')

You can disable this script with the kernel command line parameter
disable-root-to=yes.

I tested, once with overlay fs and once without overlay fs. vlc starts
as long as you do not use overlay fs. But it does not start with enabled
overlay fs.

Therefore, the reason must be the overlay filesystem. It can be assumed
that thus bug affects all systems that use overlay fs. Not only debian
but all distributions. Therefore, I would give this bug a high priority.

In addition, my strace looks a bit different than the strace that has
been posted here (see attachment). Last 5 lines:

mmap2(NULL, 26374, PROT_READ, MAP_SHARED, 3, 0) = 0xb7f94000
close(3)= 0
futex(0xb7f2bfe4, FUTEX_WAKE_PRIVATE, 2147483647) = 0
exit_group(1)   = ?
+++ exited with 1 +++

I suspect the futex () call fails.

The bug probably has nothing to do with /proc/self/maps.

[Bug 1843181] [NEW] cryptsetup-reencrypt may use an incorrect hash if the hash parameter is omitted

2019-09-08 Thread Matthias Kruzenski
Public bug reported:

Let's say:

- someone setup a fully encrypted bootable ubuntu system
- the /boot directory resists in the encrypted root filesystem so that it is 
also encrypted
- the parameters --cipher=aes-xts-plain64 and --hash=sha512 have been passed to 
cryptsetup luksFormat
- everything was configured correctly so that GRUB is able to boot the 
encrypted system
- everything works fine, when you turn on the computer you will be prompted to 
unlock the encrypted system


Let's get to the problem:

- for some reason someone want to re-encrypt the entire system which is easily 
possible with cryptsetup-reencrypt
- this is done with the following command: cryptsetup-reencrypt /dev/sda3 
--key-file=secret.key --key-slot 0
- the re-encryption process is successful
- but the system is now no longer bootable because cryptsetup-reencrypt has 
used sha256 as hash and NOT sha512 which was used before


The reason why the system is unbootable is:

- the "early grub core image" which was created by grub-install does not
contain an sha256 module, and because of that grub is no longer able to
read the encrypted volume in stage 1

Conclusion:

- if no cipher and/or hash was passed to cryptsetup-reencrypt then
cryptsetup-reencrypt should take over the previous values of the
encrypted volume and not use the default hash value which is sha256,
only then the system will still be bootable


Note:

- I can confirm that the system is still bootable if the parameters
--cipher=aes-xts-plain64 and --hash=sha512 are passed to cryptsetup-
reencrypt explicitly


I know:

- grub-install could solve the issue but I think this is not the best
solution and the behavior described here should be considered as a bug.
A user expects everything to work without problems, and that everything
is same like before (same cipher, same hash).


Summery:

cryptsetup-reencrypt should simply re-encrypt, it should not make any
decisions regarding the hash or cipher since the consequences are not
foreseeable.

[Bug 1247905] Re: update-grub fails in the face of overlayroot

2019-07-20 Thread Matthias Kruzenski
WORKING SOLUTION


After encountering this problem, I developed a very simple solution:


nano /usr/sbin/grub-probe-overlay

-[BEGIN]--
#!/bin/sh

ARGS=

for ARG in $@; do
if [ "${ARG%%[!/]*}" = "/" ]; then

OPTIONS=

if FSTYPE=$( findmnt -n -o FSTYPE "$ARG" ); then
if [ "$FSTYPE" = "overlay" ]; then
OPTIONS=$(findmnt -n -o OPTIONS "$ARG")
fi
elif FSTYPE=$( findmnt -n -o FSTYPE / ); then
if [ "$FSTYPE" = "overlay" ]; then
OPTIONS=$(findmnt -n -o OPTIONS /)
fi
fi

if LOWERDIR=$(echo "$OPTIONS" | grep -m 1 -oP 
'lowerdir=\K[^,]+'); then
#   echo "[DEBUG] Overlay filesystem detected \${ARG} --> 
\${LOWERDIR}\${ARG%*/}" 1>&2
ARG="${LOWERDIR}${ARG%*/}"
fi
fi
ARGS="$ARGS $ARG"
done

grub-probe-default $ARGS

exit $?
-[END]


mv /usr/sbin/grub-probe /usr/sbin/grub-probe-default

ln -s /usr/sbin/grub-probe-overlay /usr/sbin/grub-probe


OPTIONAL STEP:
==

apt-mark hold grub-pc

NOTE: package name can also be "grub-efi-amd64" or "grub-efi-ia32" or
something else, depending on what you use

PROS

- works perfectly with overlay filesystem
- shows a general solution (maybe someone can use it to fix the grub-probe 
source code)
- no patching of grub scripts required (some people tried patches as solution, 
but grub-probe is used in many grub scripts --> patching nightmare)

CONS

- grub-probe must be renamed (for this reason, I recommend that you set the 
status of your grub package to "hold")
