This patch fixes a regression [1] introduced in ntpd 4.2.8p18 [2]. ntpd[200]: Listen normally on 3 lo [::1]:123 ntpd[200]: bind(20) AF_INET6 [fe80::bf3d:254d:dee0:d345%3]:123 flags 0x811 failed: Cannot assign requested address ntpd[200]: unable to create socket on enp0s3 (4) for [fe80::bf3d:254d:dee0:d345%3]:123 ntpd[192]: daemon control: got EOF ntpd[192]: daemon child died with signal 11 systemd[1]: ntpd.service: Control process exited, code=exited, status=70/SOFTWARE systemd[1]: ntpd.service: Failed with result 'exit-code'. systemd[1]: Failed to start Network Time Service. If the IPv6 link-local interface was not ready for binding on the first attempt, ntpd would segfault in update_interfaces(). The segfault would only occur when ntpd was started as part of the boot sequence. Most - but not all - boots were affected. Evidently it could happen that the timing of ntpd's start up was delayed enough that the IPv6 link-local interface was ready for the bind() call when it was first issued by open_socket() via create_interface().

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.
