Subject: [PATCH 0/5] Drivers: hv: cleanup VMBus messages handling
Date: Wed, 1 Apr 2020 12:36:33 +0200 [thread overview]
Message-ID: <20200401103638.1406431-1-vkuznets@redhat.com> (raw)
A small cleanup series mostly aimed at sanitizing memory we pass to
message handlers: not passing garbage/lefrtovers from other messages
and making sure we fail early when hypervisor misbehaves.
No (real) functional change intended.
Vitaly Kuznetsov (5):
Drivers: hv: copy from message page only what's needed
Drivers: hv: allocate the exact needed memory for messages
Drivers: hv: avoid passing opaque pointer to vmbus_onmessage()
Drivers: hv: make sure that 'struct vmbus_channel_message_header'
compiles correctly
Drivers: hv: check VMBus messages lengths
