S390IPLState contains two IplParameterBlock, which may in turn have
either a IPLBlockPV or a IplBlockFcp, both ending with a variable
sized field (an array).
This causes a warning with clang 11 or greater, which checks that
variable sized type are only allocated at the end of the struct:
In file included from ../qemu-cfi-v3/target/s390x/diag.c:21:
../qemu-cfi-v3/hw/s390x/ipl.h:161:23: error: field 'iplb' with variable sized type 'IplParameterBlock' (aka 'union IplParameterBlock') not at the end of a struct or class is a GNU extension [-Werror,-Wgnu-variable-sized-type-not-at-end]

IplParameterBlock iplb_pv;
In this case, however, the warning is a false positive, because
IPLBlockPV and IplBlockFcp are allocated in a union wrapped at 4K,
making the union non-variable sized.
Fix the warning by turning the two variable sized arrays into arrays
of size 0. This avoids the compiler error and should produce the
same code.

LLVM's linker, LLD, supports the keyword "INSERT AFTER", starting with
version 11.
However, when multiple sections are defined in the same "INSERT AFTER",
they are added in a reversed order, compared to BFD's LD.
This patch makes fork_fuzz.ld generic enough to work with both linkers.
Each section now has its own "INSERT AFTER" keyword, so proper ordering is
defined between the sections added.

We switched to hardlinks in
a942f64cc4 ("scripts/oss-fuzz: use hardlinks instead of copying")
The motivation was to conserve space (50 fuzzers built with ASAN, can
weigh close to 9 GB).
Unfortunately, OSS-Fuzz (partially) treated the underlying copy of the
fuzzer as a standalone fuzzer. To attempt to fix, we tried:
f8b8f37463 ("scripts/oss-fuzz: rename bin/qemu-fuzz-i386")
This was also not a complete fix, because though OSS-Fuzz
ignores the renamed fuzzer, the underlying ClusterFuzz, doesn't:
https://storage.googleapis.com/clusterfuzz-builds/qemu/targets.list.addresshttps://oss-fuzz-build-logs.storage.googleapis.com/log-9bfb55f9-1c20-4aa6-a49c-ede12864eeb2.txt
(clusterfuzz still lists qemu-fuzz-i386.base as a fuzzer)
This change keeps the hard-links, but makes them all point to a file
with a qemu-fuzz-i386-target-.. name. If we have targets, A, B, C, the
result will be:
qemu-fuzz-i386-target-A (base file)
qemu-fuzz-i386-target-B -> qemu-fuzz-i386-target-A
qemu-fuzz-i386-target-C -> qemu-fuzz-i386-target-A
The result should be that every file that looks like a fuzzer to
OSS-Fuzz/ClusterFuzz, can run as a fuzzer (we don't have a separate base
copy). Unfortunately, there is not simple way to test this locally.
In the future, it might be worth it to link the majority of QEMU in as a
shared-object (see https://github.com/google/oss-fuzz/issues/4575 )

The function do_sigreturn() tries to store the PC, NPC and PSR in
uint32_t local variables, which implicitly drops the high half of
these fields for 64-bit guests.
The usual effect was that a guest which used signals would crash on
return from a signal unless it was lucky enough to take it while the
PC was in the low 4GB of the address space. In particular, Debian
/bin/dash and /bin/bash would segfault after executing external
commands.
Use abi_ulong, which is the type these fields all have in the
__siginfo_t struct.

Because QEMU's user-mode emulation just directly accesses guest CPU
state, for SPARC the guest register window state is not the same in
the sparc64_get_context() and sparc64_set_context() functions as it
is for the real kernel's versions of those functions. Specifically,
for the kernel it has saved the user space state such that the O*
registers go into a pt_regs struct as UREG_I*, and the I* registers
have been spilled onto the userspace stack. For QEMU, we haven't
done that, so the guest's O* registers are still in WREG_O* and the
I* registers in WREG_I*.
The code was already accessing the O* registers correctly for QEMU,
but had copied the kernel code for accessing the I* registers off the
userspace stack. Replace this with direct accesses to fp and i7 in
the CPU state, and add a comment explaining why we differ from the
kernel code here.
This fix is sufficient to get bash to a shell prompt.

The various structs that make up the SPARC target_ucontext had some
errors:
* target structures must not include fields which are host pointers,
which might be the wrong size. These should be abi_ulong instead
* because we don't have the 'long double' part of the mcfpu_fregs
union in our version of the target_mc_fpu struct, we need to
manually force it to be 16-aligned
In particular, the lack of 16-alignment caused sparc64_get_context()
and sparc64_set_context() to read and write all the registers at the
wrong offset, which triggered a guest glibc stack check in
siglongjmp:
*** longjmp causes uninitialized stack frame ***: terminated
when trying to run bash.

First, permission update loop tries to do iterations transactionally,
but the whole update is not transactional: nobody roll-back successful
loop iterations when some iteration fails.
Second, in the iteration we have nested permission update:
c->klass->update_filename may point to bdrv_child_cb_update_filename()
which calls bdrv_backing_update_filename(), which may do node reopen to
RW.
Permission update system is not prepared to nested updates, at least it
has intermediate permission-update state stored in BdrvChild
structures: has_backup_perm, backup_perm and backup_shared_perm.
So, let's first do bdrv_replace_node_common() (which is more
transactional than open-coded update in bdrv_drop_intermediate()) and
then call update_filename() in separate. We still do not rollback
changes in case of update_filename() failure but it's not much worse
than pre-patch behavior.
Note that bdrv_replace_node_common() does check for frozen children,
so corresponding check is dropped in bdrv_drop_intermediate().

Add new parameter to bdrv_replace_node(): auto_skip. With

parents or fail. New behaviour will be used in the following commit in
block.c, so keep original function name as public interface.
Note: new error message is a bit funny in contrast with further
"Cannot" in case of frozen child, but we'd better keep some difference
to make it possible to distinguish one from another on failure. Still,
actually we'd better refactor should_update_child() call to distinguish
also different kinds of "should not". Let's do it later.

libvhost-user is needed when CONFIG_LINUX is set. The CONFIG_VHOST_USER
check in meson.build is incorrect.
In fact, no explicit check is needed since this dependency is not built
by default. If something declares a dependency on libvhost-user then it
will be built, otherwise it won't be built (i.e. on non-Linux hosts).
This fixes ./configure --disable-vhost-user && make.
Fixes: bc15e44cb2 ("configure: introduce --enable-vhost-user-blk-server")

Back in 2015, we attempted to fix error reporting for images that
claimed to have more than INT64_MAX/512 sectors, but due to the type
promotions caused by BDRV_SECTOR_SIZE being unsigned, this
inadvertently forces all negative ret values to be slammed into -EFBIG
rather than the original error. While we're at it, we can avoid the
confusing ?: by spelling the logic more directly.

broke few tests and this test breakage went unnoticed.
Fix this test by rewriting it in python

The QCowL2Meta structure is used to store information about a part of
a write request that touches clusters that need changes in their L2
entries. This happens with newly-allocated clusters or subclusters.
This structure has changed a bit since it was first created and its
current documentation is not quite up-to-date.
A write request can span a region consisting of a combination of
clusters of different types, and qcow2_alloc_host_offset() can
repeatedly call handle_copied() and handle_alloc() to add more
clusters to the mix as long as they all are contiguous on the image
file.
Because of this a write request has a list of QCowL2Meta structures,
one for each part of the request that needs changes in the L2
metadata.
Each one of them spans nb_clusters and has two copy-on-write regions
located immediately before and after the middle region touched by that
part of the write request. Even when those regions themselves are
empty their offsets must be correct because they are used to know the
location of the middle region.
This was not always the case but it is not a problem anymore
because the only two places where QCowL2Meta structures are created
(calculate_l2_meta() and qcow2_co_truncate()) ensure that the
copy-on-write regions are correctly defined, and so do assertions like
the ones in perform_cow().
The conditional initialization of the 'written_to' variable is
therefore unnecessary and is removed by this patch.
