03d7712b4b qemu-bridge-helper: restrict interface name to IFNAMSIZ
The network interface name in Linux is defined to be of size
IFNAMSIZ(=16), including the terminating null('\0') byte.
The same is applied to interface names read from 'bridge.conf'
file to form ACL rules. If user supplied '--br=bridge' name
is not restricted to the same length, it could lead to ACL bypass
issue. Restrict interface name to IFNAMSIZ, including null byte.

4482258130 block: Fix hangs in synchronous APIs with iothreads
In the block layer, synchronous APIs are often implemented by creating a
coroutine that calls the asynchronous coroutine-based implementation and
then waiting for completion with BDRV_POLL_WHILE().

For this to work with iothreads (more specifically, when the synchronous
API is called in a thread that is not the home thread of the block
device, so that the coroutine will run in a different thread), we must
make sure to call aio_wait_kick() at the end of the operation. Many
places are missing this, so that BDRV_POLL_WHILE() keeps hanging even if
the condition has long become false.

Note that bdrv_dec_in_flight() involves an aio_wait_kick() call. This
corresponds to the BDRV_POLL_WHILE() in the drain functions, but it is
generally not enough for most other operations because they haven't set
the return value in the coroutine entry stub yet. To avoid race
conditions there, we need to kick after setting the return value.

The race window is small enough that the problem doesn't usually surface
in the common path. However, it does surface and causes easily
reproducible hangs if the operation can return early before even calling
bdrv_inc/dec_in_flight, which many of them do (trivial error or no-op
success paths).

The bug in bdrv_truncate(), bdrv_check() and bdrv_invalidate_cache() is
slightly different: These functions even neglected to schedule the
coroutine in the home thread of the node. This avoids the hang, but is
obviously wrong, too. Fix those to schedule the coroutine in the right
AioContext in addition to adding aio_wait_kick() calls.

017f271f7a device_tree: Fix integer overflowing in load_device_tree()
If the value of get_image_size() exceeds INT_MAX / 2 - 10000, the
computation of @dt_size overflows to a negative number, which then
gets converted to a very large size_t for g_malloc0() and
load_image_size().  In the (fortunately improbable) case g_malloc0()
succeeds and load_image_size() survives, we'd assign the negative
number to *sizep.  What that would do to the callers I can't say, but
it's unlikely to be good.

Fix by rejecting images whose size would overflow.

576964bf2a seccomp: don't kill process for resource control syscalls
The Mesa library tries to set process affinity on some of its threads in
order to optimize its performance. Currently this results in QEMU being
immediately terminated when seccomp is enabled.

Mesa doesn't consider failure of the process affinity settings to be
fatal to its operation, but our seccomp policy gives it no choice in
gracefully handling this denial.

It is reasonable to consider that malicious code using the resource
control syscalls to be a less serious attack than if they were trying
to spawn processes or change UIDs and other such things. Generally
speaking changing the resource control setting will "merely" affect
quality of service of processes on the host. With this in mind, rather
than kill the process, we can relax the policy for these syscalls to
return the EPERM errno value. This allows callers to detect that QEMU
does not want them to change resource allocations, and apply some
reasonable fallback logic.

The main downside to this is for code which uses these syscalls but does
not check the return value, blindly assuming they will always
succeeed. Returning an errno could result in sub-optimal behaviour.
Arguably though such code is already broken & needs fixing regardless.

375667af78 scsi-generic: avoid possible out-of-bounds access to r->buf
Whenever the allocation length of a SCSI request is shorter than the size of the
VPD page list, page_idx is used blindly to index into r->buf.  Even though
the stores in the insertion sort are protected against overflows, the same is not
true of the reads and the final store of 0xb0.

This basically does the same thing as commit 57dbb58d80 ("scsi-generic: avoid
out-of-bounds access to VPD page list", 2018-11-06), except that here the
allocation length can be chosen by the guest.  Note that according to the SCSI
standard, the contents of the PAGE LENGTH field are not altered based
on the allocation length.

The code was introduced by commit 6c219fc8a1 ("scsi-generic: keep VPD
page list sorted", 2018-11-06) but the overflow was already possible before.

86d4f40141 gluster: the glfs_io_cbk callback function pointer adds pre/post stat args
The glfs_*_async() functions do a callback once finished. This callback
has changed its arguments, pre- and post-stat structures have been
added. This makes it possible to improve caching, which is useful for
Samba and NFS-Ganesha, but not so much for QEMU. Gluster 6 is the first
release that includes these new arguments.

With an additional detection in ./configure, the new arguments can
conditionally get included in the glfs_io_cbk handler.

43a3a1b694 hw/block/pflash_cfi01: Add missing DeviceReset() handler
To avoid incoherent states when the machine resets (see bug report
below), add the device reset callback.

A "system reset" sets the device state machine in READ_ARRAY mode
and, after some delay, set the SR.7 READY bit.

Since we do not model timings, we set the SR.7 bit directly.

Both lqspi_read() and lqspi_load_cache() expect a 32-bit
aligned address.

>From UG1085 datasheet [*] chapter on 'Quad-SPI Controller':

  Transfer Size Limitations

    Because of the 32-bit wide TX, RX, and generic FIFO, all
    APB/AXI transfers must be an integer multiple of 4-bytes.
    Shorter transfers are not possible.

Set MemoryRegionOps.impl values to force 32-bit accesses,
this way we are sure we do not access the lqspi_buf[] array
out of bound.

14d9028a7d virtio-balloon: Use temporary PBP only
We still have multiple issues in the current code
- The PBP is not freed during unrealize()
- The PBP is not reset on device resets: After a reset, the PBP is stale.
- We are not indicating VIRTIO_BALLOON_F_MUST_TELL_HOST, therefore
  guests (esp. legacy guests) will reuse pages without deflating,
  turning the PBP stale. Adding that would require compat handling.

Instead, let's use the PBP only temporarily, when processing one bulk of
inflation requests. This will keep guest_page_size > 4k working (with
Linux guests). There is nothing to do for deflation requests anymore.
The pbp is only used for a limited amount of time.

07026c30c3 virtio-balloon: Fix QEMU crashes on pagesize > BALLOON_PAGE_SIZE
We are using the wrong functions to set/clear bits, effectively touching
multiple bits, writing out of range of the bitmap, resulting in memory
corruptions. We have to use set_bit()/clear_bit() instead.

Can easily be reproduced by starting a qemu guest on hugetlbfs memory,
inflating the balloon. QEMU crashes. This never could have worked
properly - especially, also pages would have been discarded when the
first sub-page would be inflated (the whole bitmap would be set).

While testing I realized, that on hugetlbfs it is pretty much impossible
to discard a page - the guest just frees the 4k sub-pages in random order
most of the time. I was only able to discard a hugepage a handful of
times - so I hope that now works correctly.

f8364784f0 virtio-balloon: Restore MADV_WILLNEED hint on balloon deflate
Prior to f6deb6d9 "virtio-balloon: Remove unnecessary MADV_WILLNEED on
deflate", the balloon device issued an madvise() MADV_WILLNEED on
pages removed from the balloon.  That would hint to the host kernel
that the pages were likely to be needed by the guest in the near
future.

It's unclear if this is actually valuable or not, and so f6deb6d9
removed this, essentially ignoring balloon deflate requests.  However,
concerns have been raised that this might cause a performance
regression by causing extra latency for the guest in certain
configurations.

So, until we can get actual benchmark data to see if that's the case,
this restores the old behaviour, issuing a MADV_WILLNEED when a page is
removed from the balloon.

38e8e9007d virtio-balloon: Fix possible guest memory corruption with inflates & deflates
This fixes a balloon bug with a nasty consequence - potentially
corrupting guest memory - but which is extremely unlikely to be
triggered in practice.

The balloon always works in 4kiB units, but the host could have a
larger page size on certain platforms.  Since ed48c59 "virtio-balloon:
Safely handle BALLOON_PAGE_SIZE < host page size" we've handled this
by accumulating requests to balloon 4kiB subpages until they formed a
full host page.  Since f6deb6d "virtio-balloon: Remove unnecessary
MADV_WILLNEED on deflate" we essentially ignore deflate requests.

Suppose we have a host with 8kiB pages, and one host page has subpages
A & B.  If we get this sequence of events -
	inflate A
	deflate A
	inflate B
- the current logic will discard the whole host page.  That's
incorrect because the guest has deflated subpage A, and could have
written important data to it.

This patch fixes the problem by adjusting our state information about
partially ballooned host pages when deflate requests are received.

118112024d virtio-balloon: Safely handle BALLOON_PAGE_SIZE < host page size
The virtio-balloon always works in units of 4kiB (BALLOON_PAGE_SIZE), but
we can only actually discard memory in units of the host page size.

Now, we handle this very badly: we silently ignore balloon requests that
aren't host page aligned, and for requests that are host page aligned we
discard the entire host page.  The latter can corrupt guest memory if its
page size is smaller than the host's.

The obvious choice would be to disable the balloon if the host page size is
not 4kiB.  However, that would break the special case where host and guest
have the same page size, but that's larger than 4kiB.  That case currently
works by accident[1] - and is used in practice on many production POWER
systems where 64kiB has long been the Linux default page size on both host
and guest.

To make the balloon safe, without breaking that useful special case, we
need to accumulate 4kiB balloon requests until we have a whole contiguous
host page to discard.

We could in principle do that across all guest memory, but it would require
a large bitmap to track.  This patch represents a compromise: we track
ballooned subpages for a single contiguous host page at a time.  This means
that if the guest discards all 4kiB chunks of a host page in succession,
we will discard it.  This is the expected behaviour in the (host page) ==
(guest page) != 4kiB case we want to support.

If the guest scatters 4kiB requests across different host pages, we don't
discard anything, and issue a warning.  Not ideal, but at least we don't
corrupt guest memory as the previous version could.

Warning reporting is kind of a compromise here.  Determining whether we're
in a problematic state at realize() time is tricky, because we'd have to
look at the host pagesizes of all memory backends, but we can't really know
if some of those backends could be for special purpose memory that's not
subject to ballooning.

Reporting only when the guest tries to balloon a partial page also isn't
great because if the guest page size happens to line up it won't indicate
that we're in a non ideal situation.  It could also cause alarming repeated
warnings whenever a migration is attempted.

So, what we do is warn the first time the guest attempts balloon a partial
host page, whether or not it will end up ballooning the rest of the page
immediately afterwards.

[1] Because when the guest attempts to balloon a page, it will submit
    requests for each 4kiB subpage.  Most will be ignored, but the one
    which happens to be host page aligned will discard the whole lot.

83cddbaadf virtio-balloon: Use ram_block_discard_range() instead of raw madvise()
Currently, virtio-balloon uses madvise() with MADV_DONTNEED to actually
discard RAM pages inserted into the balloon.  This is basically a Linux
only interface (MADV_DONTNEED exists on some other platforms, but doesn't
always have the same semantics).  It also doesn't work on hugepages and has
some other limitations.

It turns out that postcopy also needs to discard chunks of memory, and uses
a better interface for it: ram_block_discard_range().  It doesn't cover
every case, but it covers more than going direct to madvise() and this
gives us a single place to update for more possibilities in future.

There are some subtleties here to maintain the current balloon behaviour:

* For now, we just ignore requests to balloon in a hugepage backed region.
  That matches current behaviour, because MADV_DONTNEED on a hugepage would
  simply fail, and we ignore the error.

* If host page size is > BALLOON_PAGE_SIZE we can frequently call this on
  non-host-page-aligned addresses.  These would also fail in madvise(),
  which we then ignored.  ram_block_discard_range() error_report()s calls
  on unaligned addresses, so we explicitly check that case to avoid
  spamming the logs.

* We now call ram_block_discard_range() with the *host* page size, whereas
  we previously called madvise() with BALLOON_PAGE_SIZE.  Surprisingly,
  this also matches existing behaviour.  Although the kernel fails madvise
  on unaligned addresses, it will round unaligned sizes *up* to the host
  page size.  Yes, this means that if BALLOON_PAGE_SIZE < guest page size
  we can incorrectly discard more memory than the guest asked us to.  I'm
  planning to address that soon.

Errors other than the ones discussed above, will now be reported by
ram_block_discard_range(), rather than silently ignored, which means we
have a much better chance of seeing when something is going wrong.

b260cdec21 virtio-balloon: Corrections to address verification
The virtio-balloon device's verification of the address given to it by the
guest has a number of faults:
    * The addresses here are guest physical addresses, which should be
      'hwaddr' rather than 'ram_addr_t' (the distinction is admittedly
      pretty subtle and confusing)
    * We don't check for section.mr being NULL, which is the main way that
      memory_region_find() reports basic failures.  We really need to check
      that before looking at any other section fields, because
      memory_region_find() doesn't initialize them on the failure path
    * We're passing a length of '1' to memory_region_find(), but really the
      guest is requesting that we put the entire page into the balloon,
      so it makes more sense to call it with BALLOON_PAGE_SIZE

7a31a0af31 virtio-balloon: Remove unnecessary MADV_WILLNEED on deflate
When the balloon is inflated, we discard memory place in it using madvise()
with MADV_DONTNEED.  And when we deflate it we use MADV_WILLNEED, which
sounds like it makes sense but is actually unnecessary.

The misleadingly named MADV_DONTNEED just discards the memory in question,
it doesn't set any persistent state on it in-kernel; all that's necessary
to bring the memory back is to touch it.  MADV_WILLNEED in contrast
specifically says that the memory will be used soon and faults it in.

This patch simplify's the balloon operation by dropping the madvise()
on deflate.  This might have an impact on performance - it will move a
delay at deflate time until that memory is actually touched, which
might be more latency sensitive.  However:

  * Memory that's being given back to the guest by deflating the
    balloon *might* be used soon, but it equally could just sit around
    in the guest's pools until needed (or even be faulted out again if
    the host is under memory pressure).

  * Usually, the timescale over which you'll be adjusting the balloon
    is long enough that a few extra faults after deflation aren't
    going to make a difference.

f0a334345b hw/virtio/virtio-balloon: zero-initialize the virtio_balloon_config struct
In virtio_balloon_get_config() we initialize a struct virtio_balloon_config
which we then copy to guest memory. However, the local variable is not
zero initialized. This works OK at the moment because we initialize
all the fields in it; however an upcoming kernel header change will
add some new fields. If we don't zero out the whole struct then we
will start leaking a small amount of the contents of QEMU's stack
to the guest as soon as we update linux-headers/ to a set of headers
that includes the new fields.

As a result crs_replace_with_free_ranges does not get sorted ranges and
incorrectly computes PCI64 free space regions. Which then makes linux
guest complain about device and PCI64 hole intersection and device
becomes unusable.

Fix that by returning exactly fitting ranges.

261d7f653a iotests: Test unaligned raw images with O_DIRECT
We already have 221 for accesses through the page cache, but it is
better to create a new file for O_DIRECT instead of integrating those
test cases into 221.  This way, we can make use of
_supported_cache_modes (and _default_cache_mode) so the test is
automatically skipped on filesystems that do not support O_DIRECT.

As part of the split, add _supported_cache_modes to 221.  With that, it
no longer fails when run with -c none or -c directsync.

044b0bcedf block/file-posix: Unaligned O_DIRECT block-status
Currently, qemu crashes whenever someone queries the block status of an
unaligned image tail of an O_DIRECT image:
$ echo > foo
$ qemu-img map --image-opts driver=file,filename=foo,cache.direct=on
Offset          Length          Mapped to       File
qemu-img: block/io.c:2093: bdrv_co_block_status: Assertion `*pnum &&
QEMU_IS_ALIGNED(*pnum, align) && align > offset - aligned_offset'
failed.

This is because bdrv_co_block_status() checks that the result returned
by the driver's implementation is aligned to the request_alignment, but
file-posix can fail to do so, which is actually mentioned in a comment
there: "[...] possibly including a partial sector at EOF".

Fix this by rounding up those partial sectors.

There are two possible alternative fixes:
(1) We could refuse to open unaligned image files with O_DIRECT
    altogether.  That sounds reasonable until you realize that qcow2
    does necessarily not fill up its metadata clusters, and that nobody
    runs qemu-img create with O_DIRECT.  Therefore, unpreallocated qcow2
    files usually have an unaligned image tail.

(2) bdrv_co_block_status() could ignore unaligned tails.  It actually
    throws away everything past the EOF already, so that sounds
    reasonable.
    Unfortunately, the block layer knows file lengths only with a
    granularity of BDRV_SECTOR_SIZE, so bdrv_co_block_status() usually
    would have to guess whether its file length information is inexact
    or whether the driver is broken.

Fixing what raw_co_block_status() returns is the safest thing to do.

There seems to be no other block driver that sets request_alignment and
does not make sure that it always returns aligned values.

The reproducer I used is a qcow2 image on gluster volume, where the
virtual disk size (4 GB) is larger than the gluster volume size (64M),
so we can easily trigger an ENOSPC. This backend is assigned to a
virtio-blk device using an iothread, and then from the guest a
'dd if=/dev/zero of=/dev/vda bs=1G count=1' causes the VM to stop
because of an I/O error. qemu_gluster_co_flush_to_disk() sets
bs->drv = NULL on error, so when virtio-blk stops the dataplane, the
block nodes stay in the iothread AioContext. A 'quit' monitor command
issued from this paused state crashes the process.

c627cc38be qcow2: Avoid COW during metadata preallocation
Limiting the allocation to INT_MAX bytes isn't particularly clever
because it means that the final cluster will be a partial cluster which
will be completed through a COW operation. This results in unnecessary
data read and write requests which lead to an unwanted non-sparse
filesystem block for metadata preallocation.

Align the maximum allocation size down to the cluster size to avoid this
situation.

Open files and directories with O_NOFOLLOW to avoid symlinks attacks.
While being at it also add O_CLOEXEC.

usb-mtp only handles regular files and directories and ignores
everything else, so users should not see a difference.

Because qemu ignores symlinks, carrying out a successful symlink attack
requires swapping an existing file or directory below rootdir for a
symlink and winning the race against the inotify notification to qemu.

847fe10828 configure: improve usbfs check
The current check to test if usbfs support should be compiled or not
solely relies on the presence of <linux/usbdevice_fs.h>, without
actually checking that all definition used by Qemu are provided by
this header file.

With sufficiently old kernel headers, <linux/usbdevice_fs.h> may be
present, but some of the definitions needed by Qemu may not be
available.

This commit improves the check by building a small program that
actually tests whether the necessary definitions are available.

In addition, it fixes a bug where have_usbfs was set to "yes"
regardless of the result of the test.

f3a70a4ae1 qga-win: include glib when building VSS DLL
Commit 3ebee3b191 defined assert() as g_assert(), but when we build
the VSS DLL component of QGA (to handle fsfreeze) we do not include
glib, which results in breakage when building with VSS support enabled.

Fix this by including glib (along with the -lintl and -lws2_32
dependencies it brings).

Since the VSS DLL is built statically, this introduces an additional
dependency on static glib and supporting libs for the mingw environment
(possibly why we didn't include glib originally), but VSS support
already has very specific prerequisites so it shouldn't affect too many
build environments.

Since the VSS DLL code does use qemu/osdep.h, this should also help
avoid future breakages and possibly allow for some clean ups in current
VSS code.

d7cae05bf5 json: Fix % handling when not interpolating
Commit 8bca4613 added support for %% in json strings when interpolating,
but in doing so broke handling of % when not interpolating.

When parse_string() is fed a string token containing '%', it skips the
'%' regardless of ctxt->ap, i.e. even it's not interpolating.  If the
'%' is the string's last character, it fails an assertion.  Else, it
"merely" swallows the '%'.

Fix parse_string() to handle '%' specially only when interpolating.

To gauge the bug's impact, let's review non-interpolating users of this
parser, i.e. code passing NULL context to json_message_parser_init():

* tests/check-qjson.c, tests/test-qobject-input-visitor.c,
  tests/test-visitor-serialization.c

  Plenty of tests, but we still failed to cover the buggy case.

* monitor.c: QMP input

* qga/main.c: QGA input

* qobject_from_json():

  - qobject-input-visitor.c: JSON command line option arguments of
    -display and -blockdev

    Reproducer: -blockdev '{"%"}'

  - block.c: JSON pseudo-filenames starting with "json:"

    Reproducer: https://bugzilla.redhat.com/show_bug.cgi?id=1668244#c3

  - block/rbd.c: JSON key pairs

    Pseudo-filenames starting with "rbd:".

Command line, QMP and QGA input are trusted.

Filenames are trusted when they come from command line, QMP or HMP.
They are untrusted when they come from from image file headers.
Example: QCOW2 backing file name.  Note that this is *not* the security
boundary between host and guest.  It's the boundary between host and an
image file from an untrusted source.

Neither failing an assertion nor skipping a character in a filename of
your choice looks exploitable.  Note that we don't support compiling
with NDEBUG.

27df37c1ea block: Fix invalidate_cache error path for parent activation
bdrv_co_invalidate_cache() clears the BDRV_O_INACTIVE flag before
actually activating a node so that the correct permissions etc. are
taken. In case of errors, the flag must be restored so that the next
call to bdrv_co_invalidate_cache() retries activation.

Restoring the flag was missing in the error path for a failed
parent->role->activate() call. The consequence is that this attempt to
activate all images correctly fails because we still set errp, however
on the next attempt BDRV_O_INACTIVE is already clear, so we return
success without actually retrying the failed action.

An example where this is observable in practice is migration to a QEMU
instance that has a raw format block node attached to a guest device
with share-rw=off (the default) while another process holds
BLK_PERM_WRITE for the same image. In this case, all activation steps
before parent->role->activate() succeed because raw can tolerate other
writers to the image. Only the parent callback (in particular
blk_root_activate()) tries to implement the share-rw=on property and
requests exclusive write permissions. This fails when the migration
completes and correctly displays an error. However, a manual 'cont' will
incorrectly resume the VM without calling blk_root_activate() again.

This case is described in more detail in the following bug report:
https://bugzilla.redhat.com/show_bug.cgi?id=1531888

Fix this by correctly restoring the BDRV_O_INACTIVE flag in the error
path.

00d0932e0b exec.c: Don't reallocate IOMMUNotifiers that are in use
The tcg_register_iommu_notifier() code has a GArray of
TCGIOMMUNotifier structs which it has registered by passing
memory_region_register_iommu_notifier() a pointer to the embedded
IOMMUNotifier field. Unfortunately, if we need to enlarge the
array via g_array_set_size() this can cause a realloc(), which
invalidates the pointer that memory_region_register_iommu_notifier()
put into the MemoryRegion's iommu_notify list. This can result
in segfaults.

Switch the GArray to holding pointers to the TCGIOMMUNotifier
structs, so that we can individually allocate and free them.

85bfce130a hw/s390x: Fix bad mask in time2tod()
Since "s390x/tcg: avoid overflows in time2tod/tod2time", the
time2tod() function tries to deal with the 9 uppermost bits in the
time value, but uses the wrong mask for this: 0xff80000000000000 should
be used instead of 0xff10000000000000 here.

After analyzing the log information, it seems that qemu doesn't
change the Link Status from active to inactive after hot-unplug.
This results in the abnormal log after the linux kernel commit
d331710ea78fea merged.

Furthermore, If I hotplug the same virtio-blk disk after hot-unplug,
the virtio-blk would turn on and then back off.

So this patch set the Link Status inactive after hot-unplug and
active after hot-plug.

def04278d1 iotests: make 235 work on s390 (and others)
"-machine pc" will not work all architectures. Lets fall back to the
default machine by not specifying it.

In addition we also need to specify -no-shutdown on s390 as qemu will
exit otherwise.

Clang 3.4 considers duplicate typedef in ppc4xx_i2c.h and
bitbang_i2c.h an error even if they are identical. Move it to a common
place to allow building with this clang version.

1.1 Multiline Indent
There are several places where indent is necessary:
- if/else
- while/for
- function definition & call
When breaking up a long line to fit within line width, we need a proper indent
for the following lines.
In case of if/else, while/for, align the secondary lines just after the
opening parenthesis of the first.
For example:
if (a == 1 &&
b == 2) {
while (a == 1 &&
b == 2) {
In case of function, there are several variants:
* 4 spaces indent from the beginning
* align the secondary lines just after the opening parenthesis of the

do_something(x, y,

do_something(x, y,

do_something(x, do_another(y,
