[PATCH] dbus: Fix use-after-free in property changed signals
by Mat Martineau
Configuring with --enable-asan and running test-dbus-properties revealed
that properties_set_complete() was accessing a reply message after it
was sent, but l_dbus_send() had already unref'd and freed the message.
Grabbing a reference to the reply before sending fixes the problem.

[PATCH] unit: Clean up leaks in test-dbus-watch
by Mat Martineau
Use of the internal _dbus_message_set_sender() function in
test-dbus-watch resulted in message structures that were not completely
freed, which caused error reports when ELL was configured with
--enable-asan. Manually clearing the message sender resolves the
problem.

[PATCH 0/5] Bug fixes, new compiler warnings, and test enhancements
by Mat Martineau
When I tried to build ELL using gcc 7.1.1 it failed due to some switch case
fall-throughs. One of those was an actual bug.
Patches 1 and 2 are the most critical. They fix the settings bug and add test
code to trigger the bug and verify the fix.
Patch 3 does not change run-time behavior, but does fix siphash compilation
under gcc 7.
The last two patches are test enhancements that I sent previously but were not
applied.
Mat Martineau (5):
settings: Fix string escaping bug
unit: Better coverage of escaped characters in settings strings
siphash: Fix fallthrough compiler warnings
unit: Add DH test case where results have leading zeros
unit: Make checksum unit tests verify checksum results
