-
-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] 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.
