Bugzilla: 1079013
Upstream-status: Queued in netdev tree
From 36d5fe6a000790f56039afe26834265db0a3ad4c Mon Sep 17 00:00:00 2001
From: Zoltan Kiss <zoltan.kiss@citrix.com>
Date: Wed, 26 Mar 2014 22:37:45 +0000
Subject: core, nfqueue, openvswitch: Orphan frags in skb_zerocopy and handle
errors
skb_zerocopy can copy elements of the frags array between skbs, but it doesn't
orphan them. Also, it doesn't handle errors, so this patch takes care of that
as well, and modify the callers accordingly. skb_tx_error() is also added to
the callers so they will signal the failed delivery towards the creator of the
skb.

From c4aa64b54ecc029579b0c62e976d747a0e567dfc Mon Sep 17 00:00:00 2001
From: Hans de Goede <hdegoede@redhat.com>

Subject: [PATCH] input: cypress_ps2: Don't report the cypress PS/2 trackpads
as a button pad
The cypress PS/2 trackpad models supported by the cypress_ps2 driver emulate
BTN_RIGHT events in firmware based on the finger position, as part of this
no motion events are sent when the finger is in the button area.
The INPUT_PROP_BUTTONPAD property is there to indicate to userspace that
BTN_RIGHT events should be emulated in userspace, which is not necessary
in this case.
When INPUT_PROP_BUTTONPAD is advertised userspace will wait for a motion event
before propagating the button event higher up the stack, as it needs current
abs x + y data for its BTN_RIGHT emulation. Since in the cypress_ps2 pads
don't report motion events in the button area, this means that clicks in the
button area end up being ignored, so INPUT_PROP_BUTTONPAD actually causes
problems for these touchpads, and removing it fixes:

When mergeable buffers are disabled, and the
incoming packet is too large for the rx buffer,
get_rx_bufs returns success.
This was intentional in order for make recvmsg
truncate the packet and then handle_rx would
detect err != sock_len and drop it.
Unfortunately we pass the original sock_len to
recvmsg - which means we use parts of iov not fully
validated.
Fix this up by detecting this overrun and doing packet drop
immediately.

Changes from v1:
Fix CVE# in the commit log.
Patch is unchanged.
Note: this is needed for -stable.
I wonder if this can still make the release.

vhost fails to validate negative error code
from vhost_get_vq_desc causing
a crash: we are using -EFAULT which is 0xfffffff2
as vector size, which exceeds the allocated size.
The code in question was introduced in commit
8dd014adfea6f173c1ef6378f7e5e7924866c923
