Subject: [PATCH] io: monitor encoutput buffer size from websocket GSource
The websocket GSource is monitoring the size of the rawoutput
buffer to determine if the channel can accepts more writes.
The rawoutput buffer, however, is merely a temporary staging
buffer before data is copied into the encoutput buffer. Thus
its size will always be zero when the GSource runs.
This flaw causes the encoutput buffer to grow without bound
if the other end of the underlying data channel doesn't
read data being sent. This can be seen with VNC if a client
is on a slow WAN link and the guest OS is sending many screen
updates. A malicious VNC client can act like it is on a slow
link by playing a video in the guest and then reading data
very slowly, causing QEMU host memory to expand arbitrarily.
This issue is assigned CVE-2017-15268, publically reported in
https://bugs.launchpad.net/qemu/+bug/1718964

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).

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] 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.

DOC_CONTENTS="If you don't have kvm compiled into the kernel, make sure you have the
kernel module loaded before running kvm. The easiest way to ensure that the
kernel module is loaded is to load it on boot.
For AMD CPUs the module is called 'kvm-amd'.
For Intel CPUs the module is called 'kvm-intel'.
Please review /etc/conf.d/modules for how to load these.
Make sure your user is in the 'kvm' group. Just run
$ gpasswd -a <USER> kvm
then have <USER> re-login.
For brand new installs, the default permissions on /dev/kvm might not let
you access it. You can tell udev to reset ownership/perms:
$ udevadm trigger -c add /dev/kvm
If you want to register binfmt handlers for qemu user targets:
For openrc:
# rc-update add qemu-binfmt
For systemd:
# ln -s /usr/share/qemu/binfmt.d/qemu.conf /etc/binfmt.d/qemu.conf"

DOC_CONTENTS="If you don't have kvm compiled into the kernel, make sure you have the
kernel module loaded before running kvm. The easiest way to ensure that the
kernel module is loaded is to load it on boot.
For AMD CPUs the module is called 'kvm-amd'.
For Intel CPUs the module is called 'kvm-intel'.
Please review /etc/conf.d/modules for how to load these.
Make sure your user is in the 'kvm' group. Just run
$ gpasswd -a <USER> kvm
then have <USER> re-login.
For brand new installs, the default permissions on /dev/kvm might not let
you access it. You can tell udev to reset ownership/perms:
$ udevadm trigger -c add /dev/kvm
If you want to register binfmt handlers for qemu user targets:
For openrc:
# rc-update add qemu-binfmt
For systemd:
# ln -s /usr/share/qemu/binfmt.d/qemu.conf /etc/binfmt.d/qemu.conf"
