From 284ff94d1e2c50f7314d5a60e0a45d6710160420 Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Mon, 30 Sep 2013 12:03:39 +0200 Subject: [PATCH 09/25] scsi: Fix scsi_bus_legacy_add_drive() scsi-generic with serial MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit RH-Author: Markus Armbruster Message-id: <1380542619-20274-2-git-send-email-armbru@redhat.com> Patchwork-id: 54583 O-Subject: [PATCH 7.0 qemu-kvm 1/1] scsi: Fix scsi_bus_legacy_add_drive() scsi-generic with serial Bugzilla: 1009285 RH-Acked-by: Paolo Bonzini RH-Acked-by: Gerd Hoffmann RH-Acked-by: Luiz Capitulino From: Markus Armbruster scsi_bus_legacy_add_drive() creates either a scsi-disk or a scsi-generic device. It sets property "serial" to argument serial unless null. Crashes with scsi-generic, because it doesn't have such the property. Only usb_msd_initfn_storage() passes non-null serial. Reproducer: $ qemu-system-x86_64 -nodefaults -display none -S -usb \ -drive if=none,file=/dev/sg1,id=usb-drv0 \ -device usb-storage,id=usb-msd0,drive=usb-drv0,serial=123 qemu-system-x86_64: -device usb-storage,id=usb-msd0,drive=usb-drv0,serial=123: Property '.serial' not found Aborted (core dumped) Fix by handling exactly like "removable": set the property only when it exists.
