Subject: [dpdk-stable] patch 'power: fix sanity checks for guest channel read' has been queued to stable release 19.11.9
Date: Thu, 10 Jun 2021 14:05:56 +0200	[thread overview]
Message-ID: <20210610120641.885862-8-christian.ehrhardt@canonical.com> (raw)
In-Reply-To: <20210610120641.885862-1-christian.ehrhardt@canonical.com>

Hi,

FYI, your patch has been queued to stable release 19.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/12/21. 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. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/cpaelzer/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/cpaelzer/dpdk-stable-queue/commit/ae9f70495f3eee5376e9587dccc5a12313de5683

Thanks.

Christian Ehrhardt <christian.ehrhardt@canonical.com>

Subject: [PATCH] power: fix sanity checks for guest channel read

[ upstream commit 1fe00fd358c0b5cab798010a69e758bfead9fd84 ]

In function power_guest_channel_read_msg, 'lcore_id' is used before
validity check, which may cause buffer 'global_fds' accessed by index
'lcore_id' overflow.

This patch moves the validity check of 'lcore_id' before the 'lcore_id'
being used for the first time.

Fixes: 9dc843eb273b ("power: extend guest channel API for reading")
