From: Dan Carpenter Date: Tue, 13 Dec 2016 12:27:04 +0000 (+0300) Subject: target/iscsi: Fix double free in lio_target_tiqn_addtpg() X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a91918cd3ea11f91c68e08e1e8ce1b560447a80e;p=linux-beck.git 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.
