+Subject: [PATCH] conf: don't load sourcedir during initstepslew and RTC init
+
+If the reload sources command was received in the chronyd start-up
+sequence with initstepslew and/or RTC init (-s option), the sources
+loaded from sourcedirs caused a crash due to failed assertion after
+adding sources specified in the config.
+
+Ignore the reload sources command until chronyd enters the normal
+operation mode.
+
+Fixes: 519796de3756 ("conf: add sourcedirs directive")
+
+Conflict:The log feature is added in the pre-patch. Therefore, the test cases are adapted.

+Subject: [PATCH] ntp: fix finalization for async resolver
+
+If an attempt to resolve addresses of an NTP server is made right before
+starting the termination sequence, the asynchronous resolver thread
+could read the server name when it was already freed.
+
+Leave unresolved sources allocated in NSR_Finalise() if the async
+resolver did not finish yet, at least for now. Waiting for the resolving
+result or cancelling the thread would complicate the code. The scheduler
+is not expected to be running at this point.
