Subject: [PATCH 0/2] virtio-i2c: Fix buffer handling
Date: Tue, 19 Oct 2021 09:46:45 +0200 [thread overview]
Message-ID: <20211019074647.19061-1-vincent.whitchurch@axis.com> (raw)
This fixes a couple of bugs in the buffer handling in virtio-i2c which can
result in incorrect data on the I2C bus or memory corruption in the guest.
I tested this on UML (virtio-uml needs a bug fix too, I will sent that out
later) with the device implementation in rust-vmm/vhost-device.
Vincent Whitchurch (2):
i2c: virtio: disable timeout handling
i2c: virtio: fix completion handling
