Subject: [Qemu-devel] PATCH V2: fix NULL dereferences / races between task completition and abort
Date: Wed, 15 Aug 2012 09:09:53 +0200 [thread overview]
Message-ID: <1345014594-6020-1-git-send-email-s.priebe@profihost.ag> (raw)
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
