This commit bump the kernel version of this docker test (5.4->6.18), and thus
fixes several issues preventing the Docker Compose runtime test from
succeeding due to this bump:
Kernel Infrastructure:
The Docker daemon failed to start because the 'nat' table could not
be initialized. This was due to missing legacy Netfilter support.
- Enable CONFIG_NETFILTER_XTABLES_LEGACY to support iptables nat table.
- Enable CONFIG_NAMESPACES and CONFIG_USER_NS for container isolation.
- Enable CONFIG_TUN and CONFIG_VETH for container networking.
- Enable CONFIG_IKCONFIG and CONFIG_IKCONFIG_PROC for easier debugging.
Build Fixes:
While building the kernel tools, the libelf header was missing because
objtool was not handled correctly for this kernel version. This resulted
in a fatal error: "gelf.h: No such file or directory".
- Select BR2_LINUX_KERNEL_NEEDS_HOST_LIBELF=y to build host-libelf.
Resources and Stability:
The previous 512MB of RAM was tight for the stack (Kernel +
Docker + Containerd + Python), potentially leading to Out-Of-Memory kills.
Idem for the disk size for Docker images/layers storage.
- Increase QEMU RAM to 1024MB (-m 1024M).
- Increase rootfs size to 1024MB.
- Switch to EXT4 (BR2_TARGET_ROOTFS_EXT2_4=y) for better stability
and modern feature support required by Docker's storage drivers.
Test Script Adjustments:
- Update rootfs path in the test script to point to rootfs.ext4.
