This patch fixes a regression introduced in ntpd revision 1.4040.1.4[1].
|
|
The first ntpd release to be affected was 4.2.8p18.
|
|
|
|
If the IPv6 link-local interface was not ready for binding on the first
|
|
attempt, ntpd would segfault in update_interfaces(). The cause was the
|
|
inadvertent referencing of the endpoint returned by create_interface() (ep,
|
|
which is NULL on error) rather than the endpoint which contained the address
|
|
information (ep2).
|
|
|
|
In the patch author's experience, 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().
|
|
|
|
No segfaults were observed by the patch's author when starting ntpd manually
|
|
after logging in.

[1] [Bug 3913] Avoid duplicate IPv6 link-local manycast associations.
|
|
Complete the switch from struct interface to endpt.
