Peter Korsgaard c4d86707cd util-linux: add two upstream patches to fix blocking on getrandom() with recent kernels
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.

README

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.
