iptables kernel modules are not being included in rootfs

[Iribe18]

Hello, 

I am adding iptables to an image built with https://github.com/Freescale/fsl-community-bsp-platform/tree/rocko.

To modify the kernel config I use "bitbake -c menuconfig linux-imx" and enable the required netfilter modules, I also added iptables and kernel-modules in my local.conf file:

PACKAGE_CLASSES ?= "package_ipk"

CORE_IMAGE_EXTRA_INSTALL += " kernel-modules"

IMAGE_INSTALL += " \

    kernel-modules \

    iptables

"

The kernel modules for netfilter are not added to the rootfs and the packages are not generated in tmp/deploy/ipk

The kernel version is 4.9.11.

Seems related to: https://community.nxp.com/t5/i-MX-Processors/ip-tables-does-not-get-included-in-kernel-modules/td-p/...

Could be related to the rocko version of fsl-community-bsp-platform?.

Thanks for your help.

Solution:

To enable any kernel module, in this case ip_tables, follow the next steps:

execute:

bitbake -c menuconfig linux-imx

Enable any kernel modules that you need to include in the image, in this case iptables (netfilter), and select save.

Use M to select the module to be included.

Then execute:

bitbake linux-imx -f -c compile

then build your image:

bitbake core-image-minimal

This will include the kernel modules in the rootfs
