Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> md/dm-raid: don&amp;#39;t call md_reap_sync_thread() directly<br /> <br /> Currently md_reap_sync_thread() is called from raid_message() directly<br /> without holding &amp;#39;reconfig_mutex&amp;#39;, this is definitely unsafe because<br /> md_reap_sync_thread() can change many fields that is protected by<br /> &amp;#39;reconfig_mutex&amp;#39;.<br /> <br /> However, hold &amp;#39;reconfig_mutex&amp;#39; here is still problematic because this<br /> will cause deadlock, for example, commit 130443d60b1b ("md: refactor<br /> idle/frozen_sync_thread() to fix deadlock").<br /> <br /> Fix this problem by using stop_sync_thread() to unregister sync_thread,<br /> like md/raid did.
