Fixes the following security issues:
CVE-2019-11365: An issue was discovered in atftpd in atftp 0.7.1. A remote
attacker may send a crafted packet triggering a stack-based buffer overflow
due to an insecurely implemented strncpy call. The vulnerability is
triggered by sending an error packet of 3 bytes or fewer. There are
multiple instances of this vulnerable strncpy pattern within the code base,
specifically within tftpd_file.c, tftp_file.c, tftpd_mtftp.c, and
tftp_mtftp.c.
CVE-2019-11366: An issue was discovered in atftpd in atftp 0.7.1. It does
not lock the thread_list_mutex mutex before assigning the current thread
data structure. As a result, the daemon is vulnerable to a denial of
service attack due to a NULL pointer dereference. If thread_data is NULL
when assigned to current, and modified by another thread before a certain
tftpd_list.c check, there is a crash when dereferencing current->next.

Patch 0001-Makefile.am-link-against-libpthread-for-atftp.patch patches
Makefile.am, so add _AUTORECONF.
CFLAGS is now correctly handled since commit f9dbb96844167f (configure.ac:
fix hard setting of CFLAGS), so drop the workaround about passing
-fgnu89-inline in CPPFLAGS.
Add a hash for the license file.

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
