Subject: | [Qemu-devel] PATCH V2: fix NULL dereferences / races between task completition and abort |
Date: | Wed, 15 Aug 2012 09:09:53 +0200 |
This patch fixes two main issues with block/iscsi.c: 1.) iscsi_task_mgmt_abort_task_async calls iscsi_scsi_task_cancel which was also directly called in iscsi_aio_cancel 2.) a race between task completition and task abortion could happen cause the scsi_free_scsi_task were done before iscsi_schedule_bh has finished
