[pkg-lxc-devel] Bug#1135376: Breaks lxc-templates

[Michael Biebl]

Package: lxc
Version: 1:7.0.0-1
Severity: serious


Hi,

I have several debian containers that were created via
autopkgtest-build-lxc debian $release.

The latest release of lxc broke all those container.
They fail to start, upgrade, destroy or inspect.

Here is an example:

# lxc-ls
lxc-ls: ../src/lxc/confile.c: set_config_unsupported_key: 165 Invalid argument - Unsupported config key "lxc.cgroup.devices.allow"
lxc-ls: ../src/lxc/parse.c: lxc_file_for_each_line_mmap: 135 Failed to parse config file "/usr/share/lxc/config/debian.common.conf" at line "lxc.cgroup.devices.allow = c 254:0 rm"
lxc-ls: ../src/lxc/parse.c: lxc_file_for_each_line_mmap: 135 Failed to parse config file "/var/lib/lxc/autopkgtest-sid/config" at line "lxc.include = /usr/share/lxc/config/debian.common.conf"
Failed to load config for autopkgtest-trixie


/usr/share/lxc/config/debian.common.conf is shipped by lxc-templates and
included in the container configuration.

For example, the trixie lxc container using
/var/lib/lxc/autopkgtest-trixie/config:


# Template used to create this container: /usr/share/lxc/templates/lxc-debian
# Parameters passed to the template: -r trixie
# For additional config options, please look at lxc.container.conf(5)

# Uncomment the following line to support nesting containers:
#lxc.include = /usr/share/lxc/config/nesting.conf
# (Be aware this has security implications)

lxc.net.0.type = veth
lxc.net.0.hwaddr = XX:XX:XX:XX:XX:XX
lxc.net.0.link = lxcbr0
lxc.net.0.flags = up
lxc.apparmor.profile = generated
lxc.apparmor.allow_nesting = 1
lxc.rootfs.path = dir:/var/lib/lxc/autopkgtest-trixie/rootfs

# Common configuration
lxc.include = /usr/share/lxc/config/debian.common.conf

# Container specific configuration
lxc.tty.max = 4
lxc.uts.name = autopkgtest-trixie
lxc.arch = amd64
lxc.pty.max = 1024
