Subject: [Qemu-devel] [PATCH 0/3] block/iscsi: fix ioctl cancel use-after-free
Date: Fri, 2 Feb 2018 22:16:25 +0100 [thread overview]
Message-ID: <20180202211628.3661-1-stefanha@redhat.com> (raw)
Patches 1 & 2 are cleanups.
Patch 3 fixes cancellation of ioctls. Felipe showed me a trace where an acb is
cancelled and then completes twice. The second time around crashes QEMU.
Compile-tested only.
Felipe: Please let us know if this fixes the issue you are seeing. Thanks!
Stefan Hajnoczi (3):
block/iscsi: drop unused IscsiAIOCB->buf field
block/iscsi: take iscsilun->mutex in iscsi_timed_check_events()
block/iscsi: fix ioctl cancel use-after-free
