[PATCH 0/5] Drivers: hv: cleanup VMBus messages handling

From: Vitaly Kuznetsov
Date: Wed Apr 01 2020 - 06:36:47 EST


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
