+
+In this commit, if bind9 enable threads(ISC_PLATFORM_USETHREADS),
+it blocks signal SIGHUP, SIGINT and SIGTERM in isc__app_ctxstart.
+Which caused dhclient/dhcpd could not be stopped by SIGTERM.
+
+It caused systemd's reboot hung which send SIGTERM by default.

+Subject: [PATCH] dhcp: correct the intention for xml2 lib search
+
+A missing case breaks the build when libxml2 is
+required and found appropriately. The third argument
+to the function AC_SEARCH_LIB is action-if-found which
+was mistakenly been used for the case where the library
+is not found and hence breaks the configure phase
+where it shoud actually pass.
+We now pass on silently when action-if-found is
+executed.

-From: Andre McCurdy <armccurdy@gmail.com>
-Date: Thu, 21 Jul 2016 19:07:02 -0700
-Subject: [PATCH] remove dhclient-script bash dependency
-
-Take the dash compatible IPv6 link-local address test from the Debian
-version of dhclient-script.
-
-Note that although "echo -e" in the OE version of dhclient-script is
-technically bash specific too, it is supported by Busybox echo when
-Busybox is configured with CONFIG_FEATURE_FANCY_ECHO enabled (which
-is the default in the OE Busybox defconfig) therefore leave as-is.
-
-Upstream-Status: Inappropriate [OE specific]
