If a policy is built that is newer than the kernel can support, the libsepol will fail to load that policy. Indeed, a user can manually select the policy version in the config as-is. However, it is not a friendly solution. The best solution available is to set a default policy version based off of the toolchain header kernel version. While a user may have a toolchain that has older kernel headers than the built kernel, it is still better than setting the default to the maximum available version that SELinux can support. The following defaults policy versions are as follows for the given toolchain headers: 31 >= 4.13 30 >= 4.3 29 >= 3.14 28 >= 3.5 26 >= 2.6 default 25 Note: Version 27 was never released.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
