Subject: [dpdk-stable] patch 'net/ifc: do not notify before HW ready' has been queued to stable release 18.08.1
Date: Tue, 20 Nov 2018 19:12:39 +0000 [thread overview]
Message-ID: <20181120191252.30277-49-ktraynor@redhat.com> (raw)
In-Reply-To: <20181120191252.30277-1-ktraynor@redhat.com>
Hi,
FYI, your patch has been queued to stable release 18.08.1
Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/23/18. So please
shout if anyone has objections.
Also note that after the patch there's a diff of the upstream commit vs the patch applied
to the branch. If the code is different (ie: not only metadata diffs), due for example to
a change in context or macro names, please double check it.
Thanks.
Kevin Traynor

Subject: [PATCH] net/ifc: do not notify before HW ready
[ upstream commit 971c19c77c03df51aaea78648908ef269d8e0c42 ]
If the device is not clearly reset by the previous driver and holds
some invalid ring addr, and the relay thread kicks it before HW is
properly re-configured, a bad DMA request may happen.
Besides, the notify_addr which is used by the relay thread is set in
the vdpa_ifcvf_start function, if a kick relay happens before
vdpa_ifcvf_start finishes, a null addr is accessed.
Fixes: a3f8150eac6d ("net/ifcvf: add ifcvf vDPA driver")
