Subject: iscsi-target: Fix memory corruption in iscsit_logout_post_handler_diffcid
From: Nicholas Bellinger <nab@xxxxxxxxxxxxxxx>
commit b53b0d99d6fbf7d44330395349a895521cfdbc96 upstream.
This patch fixes a bug in iscsit_logout_post_handler_diffcid() where
a pointer used as storage for list_for_each_entry() was incorrectly
being used to determine if no matching entry had been found.
This patch changes iscsit_logout_post_handler_diffcid() to key off
bool conn_found to determine if the function needs to exit early.
