Subject: [PATCH] vmw_pvscsi: check message ring page count at initialisation
A guest could set the message ring page count to zero, resulting in
infinite loop. Add check to avoid it.

From a3dfd0460492f404228335278c2a4b2afd95c2f4 Mon Sep 17 00:00:00 2001
From: Paul Durrant <paul.durrant@citrix.com>
Date: Tue, 7 Mar 2017 10:55:30 +0000
Subject: [PATCH 1/6] xen: make use of xen_xc implicit in xen_common.h inlines
Doing this will make the transition to using the new libxendevicemodel
interface less intrusive on the callers of these functions, since using
the new library will require a change of handle.
NOTE: The patch also moves the 'externs' for xen_xc and xen_fmem from
xen_backend.h to xen_common.h, and the declarations from
xen_backend.c to xen-common.c, which is where they belong.

Subject: [PATCH] audio: release capture buffers
AUD_add_capture() allocates two buffers which are never released.
Add the missing calls to AUD_del_capture().
Impact: Allows vnc clients to exhaust host memory by repeatedly
starting and stopping audio capture.
Fixes: CVE-2017-8309

Subject: [PATCH] input: limit kbd queue depth
Apply a limit to the number of items we accept into the keyboard queue.
Impact: Without this limit vnc clients can exhaust host memory by
sending keyboard events faster than qemu feeds them to the guest.

functions
This patch creates inline wrapper functions in xen_common.h for all open
coded calls to xc_hvm_XXX() functions outside of xen_common.h so that use
of xen_xc can be made implicit. This again is in preparation for the move
to using libxendevicemodel.

Subject: [PATCH] 9pfs: local: forbid client access to metadata (CVE-2017-7493)
When using the mapped-file security mode, we shouldn't let the client mess
with the metadata. The current code already tries to hide the metadata dir
from the client by skipping it in local_readdir(). But the client can still
access or modify it through several other operations. This can be used to
escalate privileges in the guest.
Affected backend operations are:
- local_mknod()
- local_mkdir()
- local_open2()
- local_symlink()
- local_link()
- local_unlinkat()
- local_renameat()
- local_rename()
- local_name_to_path()
Other operations are safe because they are only passed a fid path, which
is computed internally in local_name_to_path().
This patch converts all the functions listed above to fail and return
EINVAL when being passed the name of the metadata dir. This may look
like a poor choice for errno, but there's no such thing as an illegal
path name on Linux and I could not think of anything better.
This fixes CVE-2017-7493.

Subject: [PATCH 5/6] xen: use libxendevicemodel when available
This patch modifies the wrapper functions in xen_common.h to use the
new xendevicemodel interface if it is available along with compatibility
code to use the old libxenctrl interface if it is not.

Subject: [PATCH 6/6] xen: use 5 digit xen versions
Today qemu is using e.g. the value 480 for Xen version 4.8.0. As some
Xen version tests are using ">" relations this scheme will lead to
problems when Xen version 4.10.0 is being reached.
Instead of the 3 digit schem use a 5 digit scheme (e.g. 40800 for
version 4.8.0).

Subject: [PATCH] nbd: Fully initialize client in case of failed negotiation
If a non-NBD client connects to qemu-nbd, we would end up with
a SIGSEGV in nbd_client_put() because we were trying to
unregister the client's association to the export, even though
we skipped inserting the client into that list. Easy trigger
in two terminals:
$ qemu-nbd -p 30001 --format=raw file
$ nmap 127.0.0.1 -p 30001
nmap claims that it thinks it connected to a pago-services1
server (which probably means nmap could be updated to learn the
NBD protocol and give a more accurate diagnosis of the open
port - but that's not our problem), then terminates immediately,
so our call to nbd_negotiate() fails. The fix is to reorder
nbd_co_client_start() to ensure that all initialization occurs
before we ever try talking to a client in nbd_negotiate(), so
that the teardown sequence on negotiation failure doesn't fault
while dereferencing a half-initialized object.
While debugging this, I also noticed that nbd_update_server_watch()
called by nbd_client_closed() was still adding a channel to accept
the next client, even when the state was no longer RUNNING. That
is fixed by making nbd_can_accept() pay attention to the current
state.

Subject: [PATCH] nbd: Fix regression on resiliency to port scan
Back in qemu 2.5, qemu-nbd was immune to port probes (a transient
server would not quit, regardless of how many probe connections
came and went, until a connection actually negotiated). But we
broke that in commit ee7d7aa when removing the return value to
nbd_client_new(), although that patch also introduced a bug causing
an assertion failure on a client that fails negotiation. We then
made it worse during refactoring in commit 1a6245a (a segfault
before we could even assert); the (masked) assertion was cleaned
up in d3780c2 (still in 2.6), and just recently we finally fixed
the segfault ("nbd: Fully intialize client in case of failed
negotiation"). But that still means that ever since we added
TLS support to qemu-nbd, we have been vulnerable to an ill-timed
port-scan being able to cause a denial of service by taking down
qemu-nbd before a real client has a chance to connect.
Since negotiation is now handled asynchronously via coroutines,
we no longer have a synchronous point of return by re-adding a
return value to nbd_client_new(). So this patch instead wires
things up to pass the negotiation status through the close_fn
callback function.
Simple test across two terminals:
$ qemu-nbd -f raw -p 30001 file
$ nmap 127.0.0.1 -p 30001 && \
qemu-io -c 'r 0 512' -f raw nbd://localhost:30001
Note that this patch does not change what constitutes successful
negotiation (thus, a client must enter transmission phase before
that client can be considered as a reason to terminate the server
when the connection ends). Perhaps we may want to tweak things
in a later patch to also treat a client that uses NBD_OPT_ABORT
as being a 'successful' negotiation (the client correctly talked
the NBD protocol, and informed us it was not going to use our
export after all), but that's a discussion for another day.

Subject: [PATCH] qemu-nbd: Ignore SIGPIPE
qemu proper has done so for 13 years
(8a7ddc38a60648257dc0645ab4a05b33d6040063), qemu-img and qemu-io have
done so for four years (526eda14a68d5b3596be715505289b541288ef2a).
Ignoring this signal is especially important in qemu-nbd because
otherwise a client can easily take down the qemu-nbd server by dropping
the connection when the server wants to send something, for example:
$ qemu-nbd -x foo -f raw -t null-co:// &
[1] 12726
$ qemu-io -c quit nbd://localhost/bar
can't open device nbd://localhost/bar: No export with name 'bar' available
[1] + 12726 broken pipe qemu-nbd -x foo -f raw -t null-co://
In this case, the client sends an NBD_OPT_ABORT and closes the
connection (because it is not required to wait for a reply), but the
server replies with an NBD_REP_ACK (because it is required to reply).

From 4eea6d48daa1d1f7dda3e1458b992302c1dd040e Mon Sep 17 00:00:00 2001
From: Nathaniel McCallum <npmccallum@redhat.com>
Date: Tue, 18 Jul 2017 18:19:38 -0400
Subject: [PATCH] Update references of "struct ucontext" to "ucontext_t"
Glibc used to have:
typedef struct ucontext { ... } ucontext_t;
Glibc now has:
typedef struct ucontext_t { ... } ucontext_t;
However, Qemu used "struct ucontext" in declarations. This is a
private name and compatiblity cannot be guaranteed. This patch
updates Qemu to only use the standardized type name.
