Enable mathvec explicitly on aarch64(be) since it's now enabled by default [1]. aarch64 mathvec requires at gcc-10 but Buildroot already provide gcc-11 as minimum version. Don't use --enable-fortify-source for now in order to keep original behavior while doing the glibc version bump (and because some architecture doesn't support well fortify-source, i.e Microblaze). Postpone this change to a follow up commit. Keep the "deprecated" libcrypt enabled just in case if some application are not yet ready to use an alternative such as libxcrypt. Security related changes: CVE-2023-25139: When the printf family of functions is called with a format specifier that uses an <apostrophe> (enable grouping) and a minimum width specifier, the resulting output could be larger than reasonably expected by a caller that computed a tight bound on the buffer size. The resulting larger than expected output could result in a buffer overflow in the printf family of functions.

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 OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
