From 6a16d7be932a9df1024836ccbb448de73afd3dd0 Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Mon, 3 Feb 2014 00:35:03 -0800 Subject: [PATCH] target: Fix missing length check in spc_emulate_evpd_83() Commit fbfe858fea2a ("target_core_spc: Include target device descriptor in VPD page 83") added a new length variable, but (due to a cut and paste mistake?) just checks scsi_name_len against 256 twice. Fix this to check scsi_target_len for overflow too.
