Modified files:
sbin/dhclient : dhclient.c
Log message:
Keep dhclient.leases.<if> O_EXLOCK file descriptor open for the
lifefime of the dhclient instance. Use O_NONBLOCK so RTM_* messages
are seen while trying to open the O_EXLOCK file descriptor.
Prevents a possible race during startup, ensuring only one dhclient
instance can be configuring an interface. Improves responsiveness to
interface changes during startup.
