This was due to missing legacy Netfilter support.\n - Enable CONFIG_NETFILTER_XTABLES_LEGACY to support iptables nat table.\n - Enable CONFIG_NAMESPACES and CONFIG_USER_NS for container isolation.\n - Enable CONFIG_TUN and CONFIG_VETH for container networking.\n - Enable CONFIG_IKCONFIG and CONFIG_IKCONFIG_PROC for easier debugging.\n\nBuild Fixes:\n While building the kernel tools, the libelf header was missing because\n objtool was not handled correctly for this kernel version. This resulted\n in a fatal error: \"gelf.h: No such file or directory\".\n - Select BR2_LINUX_KERNEL_NEEDS_HOST_LIBELF=y to build host-libelf.\n\nResources and Stability:\n The previous 512MB of RAM was tight for the stack (Kernel +\n Docker + Containerd + Python), potentially leading to Out-Of-Memory kills.\n Idem for the disk size for Docker images/layers storage.\n - Increase QEMU RAM to 1024MB (-m 1024M).\n - Increase rootfs size to 1024MB.\n - Switch to EXT4 (BR2_TARGET_ROOTFS_EXT2_4=y) for better stability\n and modern feature support required by Docker's storage drivers.\n\nTest Script Adjustments:\n - Update rootfs path in the test script to point to rootfs.ext4.\n\nSigned-off-by: Dowan Gullient \n---\n .../testing/conf/docker-compose-kernel.config | 26 +++++++++----------\n .../tests/package/test_docker_compose.py | 12 ++++++---\n 2 files changed, 20 insertions(+), 18 deletions(-)","diff":"diff --git a/support/testing/conf/docker-compose-kernel.config b/support/testing/conf/docker-compose-kernel.config\nindex fd28da7a4a..cbaf5dfed3 100644\n--- a/support/testing/conf/docker-compose-kernel.config\n+++ b/support/testing/conf/docker-compose-kernel.config\n@@ -1,8 +1,10 @@\n-# CONFIG_SWAP is not set\n CONFIG_SYSVIPC=y\n CONFIG_POSIX_MQUEUE=y\n #
