From a91918cd3ea11f91c68e08e1e8ce1b560447a80e Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Tue, 13 Dec 2016 15:27:04 +0300 Subject: [PATCH] target/iscsi: Fix double free in lio_target_tiqn_addtpg() This iscsit_tpg_add_portal_group() function is only called from lio_target_tiqn_addtpg(). Both functions free the "tpg" pointer on error so it's a double free bug. The memory is allocated in the caller so it should be freed in the caller and not here.
