Eric Blake a3e1505dae qcow2: Don't strand clusters near 2G intervals during commit
The qcow2_make_empty() function is reached during 'qemu-img commit',
in order to clear out ALL clusters of an image.  However, if the
image cannot use the fast code path (true if the image is format
0.10, or if the image contains a snapshot), the cluster size is
larger than 512, and the image is larger than 2G in size, then our
choice of sector_step causes problems.  Since it is not cluster
aligned, but qcow2_discard_clusters() silently ignores an unaligned
head or tail, we are leaving clusters allocated.

Enhance the testsuite to expose the flaw, and patch the problem by
ensuring our step size is aligned.

Alex Bennée 5460da501a target-arm/translate-a64: fix gen_load_exclusive
While testing rth's latest TCG patches with risu I found ldaxp was
broken. Investigating further I found it was broken by 1dd089d0 when
the cmpxchg atomic work was merged. As part of that change the code
attempted to be clever by doing a single 64 bit load and then shuffle
the data around to set the two 32 bit registers.

As I couldn't quite follow the endian magic I've simply partially
reverted the change to the original code gen_load_exclusive code. This
doesn't affect the cmpxchg functionality as that is all done on in
gen_store_exclusive part which is untouched.

I've also restored the comment that was removed (with a slight tweak
to mention cmpxchg).

Eric Blake 29a6731afb tests: Avoid qobject_from_jsonf("%"PRId64)
The qobject_from_jsonf() function implements a pseudo-printf
language for creating a QObject; however, it is hard-coded to
only parse a subset of formats understood by -Wformat, and is
not a straight synonym to bare printf().  In particular, any
use of an int64_t integer works only if the system's
definition of PRId64 matches what the parser expects; which
works on glibc (%lld or %ld depending on 32- vs. 64-bit) and
mingw (%I64d), but not on Mac OS (%qd).  Rather than enhance
the parser, it is just as easy to force the use of int (where
the value is small enough) or long long instead of int64_t,
which we know always works.

This should cover all remaining testsuite uses of
qobject_from_json[fv]() that were trying to rely on PRId64,
although my proof for that was done by adding in asserts and
checking that 'make check' still passed, where such asserts
are inappropriate during hard freeze.  A later series in 2.9
may remove all dynamic JSON parsing, but that's a bigger task.

works on glibc (%lld or %ld depending on 32- vs. 64-bit) and
mingw (%I64d), but not on Mac OS (%qd).  Rather than enhance
the parser, it is just as easy to use normal printf() for
this particular conversion, matching what is done elsewhere
in this file [1], which is safe in this instance because the
format does not contain any of the problematic differences
(bare '%' or the '%s' format).

The use of PRId64 for a variable named 'pid' is gross, but it
is a sad reality of the 64-bit mingw environment, which
mistakenly defines pid_t as a 64-bit type even though getpid()
returns 'int' on that platform [2].  Our definition of the
QGA GuestExec type defines 'pid' as a 64-bit entity, and we
can't tighten it to 'int32' unless the mingw header is fixed.
Using 'long long' instead of 'int64_t' just so that we can
stick with qobject_from_jsonv("%lld") instead of printf() is
not any prettier, since we may have later type churn anyways.

Eric Blake 043b5a4951 qmp-event: Avoid qobject_from_jsonf("%"PRId64)
The qobject_from_jsonf() function implements a pseudo-printf
language for creating a QObject; however, it is hard-coded to
only parse a subset of formats understood by -Wformat, and is
not a straight synonym to bare printf().  In particular, any
use of an int64_t integer works only if the system's
definition of PRId64 matches what the parser expects; which
works on glibc (%lld or %ld depending on 32- vs. 64-bit) and
mingw (%I64d), but not on Mac OS (%qd).  Rather than enhance
the parser, it is just as easy to use 'long long', which we
know always works.  There are few enough callers of
qobject_from_json[fv]() that it is easy to audit that this is
the only non-testsuite caller that was actually relying on
this particular conversion.

Andrey Smirnov 64f441d2e5 fsl_etsec: Pad short payloads with zeros
Depending on QEMU network setup it is possible for us to receive a
complete Ethernet packet that is less 64 bytes long. One such example is
when QEMU is configured to use a standalone TAP device (not set to be a
part of any bridge) receives and ARP packet. In cases like that we need
to add more than just 4-bytes of CRC padding and ensure that our payload
is at least 60 bytes long, such that, when combined with CRC padding
bytes the resulting size is at least 802.3 minimum MTU bytes
long (64). Failing to do that results in code in etsec_walk_rx_ring()
setting BD_RX_SH which, in turn, makes corresponding Linux driver of
emulated host to reject buffer as a runt packet

Christophe Fergeau 6c7565028c qxl: Only emit QXL_INTERRUPT_CLIENT_MONITORS_CONFIG on config changes
Currently if the client keeps sending the same monitor config to
QEMU/spice-server, QEMU will always raise
a QXL_INTERRUPT_CLIENT_MONITORS_CONFIG regardless of whether there was a
change or not.
Guest-side (with fedora 25), the kernel QXL KMS driver will also forward the
event to user-space without checking if there were actual changes.
Next in line are gnome-shell/mutter (on a default f25 install), which
will try to reconfigure everything without checking if there is anything
to do.
Where this gets ugly is that when applying the resolution changes,
gnome-shell/mutter will call drmModeRmFB, drmModeAddFB, and
drmModeSetCrtc, which will cause the primary surface to be destroyed and
recreated by the QXL KMS driver. This in turn will cause the client to
resend a client monitors config message, which will cause QEMU to reemit
an interrupt with an unchanged monitors configuration, ...
This causes https://bugzilla.redhat.com/show_bug.cgi?id=1266484

This commit makes sure that we only emit
QXL_INTERRUPT_CLIENT_MONITORS_CONFIG when there are actual configuration
changes the guest should act on.

Michael Roth 5c0139a8c2 spapr: fix default DRC state for coldplugged LMBs
Currently we set the initial isolation/allocation state for DRCs
associated with coldplugged LMBs to ISOLATED/UNUSABLE,
respectively, under the assumption that the guest will move this
state to UNISOLATED/USABLE.

In fact, this is only the case for LMBs added via hotplug. For
coldplugged LMBs, the guest actually assumes the initial state to
be UNISOLATED/USABLE.

In practice, this only becomes an issue when we attempt to unplug
one of these LMBs, where the guest kernel will issue an
rtas-get-sensor-state call to check that the corresponding DRC is
in an USABLE state before it will release the LMB back to
QEMU. If the returned state is otherwise, the guest will assume no
further action is needed, which bypasses the QEMU-side cleanup that
occurs during the USABLE->UNUSABLE transition. This results in
LMBs and their corresponding pc-dimm devices to stick around
indefinitely.

This patch fixes the issue by manually setting DRCs associated with
cold-plugged LMBs to UNISOLATED/ALLOCATED, but leaving the hotplug
state untouched. As it turns out, this is analogous to the handling
for cold-plugged CPUs in spapr_core_plug().

Laszlo Ersek 1b57bd4f2f loader: fix undefined behavior in rom_order_compare()
According to ISO C99 / N1256 (referenced in HACKING):

> 6.5.8 Relational operators
>
> 4 For the purposes of these operators, a pointer to an object that is
>   not an element of an array behaves the same as a pointer to the first
>   element of an array of length one with the type of the object as its

>
> 5 When two pointers are compared, the result depends on the relative
>   locations in the address space of the objects pointed to. If two
>   pointers to object or incomplete types both point to the same object,
>   or both point one past the last element of the same array object, they
>   compare equal. If the objects pointed to are members of the same
>   aggregate object, pointers to structure members declared later compare
>   greater than pointers to members declared earlier in the structure,
>   and pointers to array elements with larger subscript values compare
>   greater than pointers to elements of the same array with lower
>   subscript values. All pointers to members of the same union object
>   compare equal. If the expression /P/ points to an element of an array
>   object and the expression /Q/ points to the last element of the same
>   array object, the pointer expression /Q+1/ compares greater than /P/.
>   In all other cases, the behavior is undefined.

Our AddressSpace objects are allocated generally individually, and kept in
the "address_spaces" linked list, so we mustn't compare their addresses
with relops.

Convert the pointers subjected to the relop in rom_order_compare() to
"uintptr_t":

> 7.18.1.4 Integer types capable of holding object pointers
>
> 1 [...]
>
>   The following type designates an unsigned integer type with the
>   property that any valid pointer to void can be converted to this type,
>   then converted back to pointer to void, and the result will compare
>   equal to the original pointer:
>
>   /uintptr_t/
>
>   These types are optional.

Laszlo Ersek aa6c6ae843 loader: fix handling of custom address spaces when adding ROM blobs
* Commit 3e76099aac ("loader: Allow a custom AddressSpace when loading
  ROMs") introduced the "Rom.as" field:

  (1) It modified the utility callers of rom_insert() to take "as" as a
      new parameter from *their* callers, and set "rom->as" from that
      parameter. The functions covered were rom_add_file() and
      rom_add_elf_program().

  (2) It also modified rom_insert() itself, to auto-assign
      "&address_space_memory", in case the external caller passed -- and
      the utility caller forwarded -- as=NULL.

  Except, commit 3e76099aac forgot to update the third utility caller of
  rom_insert(), under point (1), namely rom_add_blob().

* Later, commit 5e774eb3bd ("loader: Add AddressSpace loading support
  to uImages") added the load_uimage_as() function, and the
  rom_add_blob_fixed_as() function-like macro, with the necessary changes
  elsewhere to propagate the new "as" parameter to rom_add_blob():

    load_uimage_as()
      load_uboot_image()
        rom_add_blob_fixed_as()
          rom_add_blob()

  At this point, the signature (and workings) of rom_add_blob() had been
  broken already, and the rom_add_blob_fixed_as() macro passed its "_as"
  parameter to rom_add_blob() as "callback_opaque". Given that the
  "fw_callback" parameter itself was set to NULL (correctly), this did no
  additional damage (the opaque arg would never be used), but ultimately
  it broke the new functionality of load_uimage_as().

* The load_uimage_as() function would be put to use in one of the later
  patches, commit e481a1f63c ("generic-loader: Add a generic loader").

* We can fix this only in a unified patch now. Append "AddressSpace *as"
  to the signature of rom_add_blob(), and handle the new parameter. Pass
  NULL from all current callers, except from rom_add_blob_fixed_as(),
  where "_as" has to be bumped to the proper position.

* Note that rom_add_file() rejects the case when both "mr" and "as" are
  passed in as non-NULL. The action that this is apparently supposed to
  prevent is the

    rom->mr = mr;

  assignment (that's the only place where the "mr" parameter is used in
  rom_add_file()). In rom_add_blob() though, we have no "mr" parameter,
  and the actions done on the fw_cfg branch:

    if (fw_file_name && fw_cfg) {
        if (mc->rom_file_has_mr) {
            data = rom_set_mr(rom, OBJECT(fw_cfg), devpath);
            mr = rom->mr;
        } else {
            data = rom->data;
        }

  reflect those that are performed by rom_add_file() too (with mr==NULL):

    if (rom->fw_file && fw_cfg) {
        if ((!option_rom || mc->option_rom_has_mr) &&
            mc->rom_file_has_mr) {
            data = rom_set_mr(rom, OBJECT(fw_cfg), devpath);
        } else {
            data = rom->data;
        }

  Hence we need no additional restrictions in rom_add_blob().

* Stable is not affected as both problematic commits appeared first in
  v2.8.0-rc0.

Paolo Bonzini 7ecf44a579 rules.mak: Also try -r to build modules
Building qemu fails in distributions where gcc enables PIE by default
(e.g. Debian unstable) with:

/usr/bin/ld: -r and -pie may not be used together

You have to use -r instead of -Wl,-r to avoid gcc passing -pie to the linker
when PIE is enabled and a relocatable object is passed.  However, clang
does not know about -r, so try -Wl,-r first.

[This is a fix for commit c96f0ee6a6
("rules.mak: Use -r instead of -Wl, -r to fix building when PIE is
default") which mostly worked but broke the ./configure --enable-modules
build with clang.

Max Reitz 6725f887ac hbitmap: Fix shifts of constants by granularity
An hbitmap's granularity may be anything from 0 to 63, so when shifting
constants by its value, they should not be plain ints.

Even having changed the types, hbitmap_serialization_granularity() still
tries to shift 64 to the right by the granularity. This operation is
undefined if the granularity is greater than 57. Adding an assertion is
fine for now, because serializing is done only in tests so far, but this
means that only bitmaps with a granularity below 58 can be serialized
and we should thus add a hbitmap_is_serializable() function later.

One of the two places touched in this patch uses
QEMU_ALIGN_UP(x, 1 << y). We can use ROUND_UP() there, since the second
parameter is obviously a power of two.
