As part of the fix for CVE-2018-1108 (kernel drivers before version 4.17-rc1 are vulnerable to a weakness in the Linux kernel's implementation of random seed data. Programs, early in the boot sequence, could use the data allocated for the seed before it was sufficiently generated), the kernel random number generator initialization routine was changed. See the project-zero writeup for more details: https://bugs.chromium.org/p/project-zero/issues/detail?id=1559 These changes have now also been backported to 4.14.x (since 4.14.39) and 4.16.x (since 4.16.7). This change unfortunately causes users of libuuid from util-linux to block for a very long time waiting for sufficient entropy. An example of this is mke2fs, which uses libuuid to generate the filesystem UUID. Fix this by backporting two post-2.31 fixes from upstream.

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
