[Bug 1641429] Re: tcpdump capture filter for vlans incorrect

2018-09-24 Thread Lukas Tribus
The kernel now longer passes vlan tag information as-is to libpcap,
instead BPF needs to access ancillary data.

That is the reason "vlan 114" works (because it does the right thing),
and a manual filter doesn't, because libpcap never actually sees this.

Offsets are negative because this is the way to access this ancillary data 
(like vlan tags) in the Linux kernel:

[Bug 1525724] Re: boot hangs with more than 1 luks device in crypttab

2016-03-27 Thread Lukas Tribus
I tried Xenial. Yes it does fix the simplified test case in this bug
(when booting doesn't require the second encrypted volume to be open),
but it doesn't fix my real issue, which is encrypting multiple devices
and putting btrfs on top of it. Adding initramfs doesn't help.

So whenever you try booting from multiple encrypted devices it will
fail.

[Bug 1525724] [NEW] boot hangs with more than 1 luks device in crypttab

2015-12-13 Thread Lukas Tribus
Public bug reported:

When /etc/crypttab has more than one luks device, the boot process locks
up (hangs) after the decryption of the first luks device. A password
prompt for the second luks device never appears.

Affected:
Ubuntu 15.04 (vivid)
Ubuntu 15.10 (wily)

Works fine in:
Ubuntu 14.10 (utopic)

When upgrading utopic to vivid in the affected configuration, the bug is
triggered as well (first boot into vivid).


Testcase:
- install (text mode) from ubuntu-15.10-server-amd64.iso
- manually partition the disk (see attached installer-partitions.png):
  -> sda1: 512mb ext2 for /boot/ (unencrypted)
  -> sda2: 4GB encrypted (luks) -> sda2_crypt
  -> sda3: 2GB encrypted (luks) -> sda3_crypt
  -> sda2_crypt: ext4 for /
  -> sda3_crypt: ext4 for /tmp

boot will hang (boot-hang.png) after decrypting sda2.

My real use-case is to encrypt multiple physical hard drivers, which
fails exactly the same way (the test config doesn't make much sense, but
its simple to reproduce).


Commenting sda3_crypt in /etc/fstab and adding a the option nofail to 
sda3_crypt in /etc/crypttab makes the OS boot.


# cat /etc/crypttab
