+[Qemu-devel] [PULL 21/41] exec: use qemu_ram_ptr_length to access guest 
+From: Prasad J Pandit <address@hidden>
+
+When accessing guest's ram block during DMA operation, use
+'qemu_ram_ptr_length' to get ram block pointer. It ensures
+that DMA operation of given length is possible; And avoids
+any OOB memory access situations.

+Subject: [PATCH] nbd/server: get rid of nbd_negotiate_read and friends
+
+Functions nbd_negotiate_{read,write,drop_sync} were introduced in
+1a6245a5b, when nbd_rwv (was nbd_wr_sync) was working through
+qemu_co_sendv_recvv (the path is nbd_wr_sync -> qemu_co_{recv/send} ->
+qemu_co_send_recv -> qemu_co_sendv_recvv), which just yields, without
+setting any handlers. But starting from ff82911cd nbd_rwv (was
+nbd_wr_syncv) works through qio_channel_yield() which sets handlers, so
+watchers are redundant in nbd_negotiate_{read,write,drop_sync}, then,
+let's just use nbd_{read,write,drop} functions.
+
+Functions nbd_{read,write,drop} has errp parameter, which is unused in
+this patch. This will be fixed later.

+Subject: [PATCH] megasas: always store SCSIRequest* into MegasasCmd
+
+This ensures that the request is unref'ed properly, and avoids a
+segmentation fault in the new qtest testcase that is added.
+This is CVE-2017-9503.

+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.
+

+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
