95c3df5a24 crypto: Avoid memory leak on failure
Commit 7836857 introduced a memory leak due to invalid use of
Error vs. visit_type_end().  If visiting the intermediate
members fails, we clear the error and unconditionally use
visit_end_struct() on the same error object; but if that
cleanup succeeds, we then skip the qapi_free call.

Until a later patch adds visit_check_struct(), the only safe
approach is to use two separate error objects.

ca47a926ad include/qemu/atomic: add compile time asserts
To be safely portable no atomic access should be trying to do more than
the natural word width of the host. The most common abuse is trying to
atomically access 64 bit values on a 32 bit host.

This patch adds some QEMU_BUILD_BUG_ON to the __atomic instrinsic paths
to create a build failure if (sizeof(*ptr) > sizeof(void *)).

ccffff48c9 cpus: don't use atomic_read for vm_clock_warp_start
As vm_clock_warp_start is a 64 bit value this causes problems for the
compiler trying to come up with a suitable atomic operation on 32 bit
hosts. Because the variable is protected by vm_clock_seqlock, we check its
value inside a seqlock critical section.

a89ef0c357 nbd: don't request FUA on FLUSH
The NBD protocol does not clearly document what will happen
if a client sends NBD_CMD_FLAG_FUA on NBD_CMD_FLUSH.
Historically, both the qemu and upstream NBD servers silently
ignored that flag, but that feels a bit risky.  Meanwhile, the
qemu NBD client unconditionally sends the flag (without even
bothering to check whether the caller cares; at least with
NBD_CMD_WRITE the client only sends FUA if requested by a
higher layer).

There is ongoing discussion on the NBD list to fix the
protocol documentation to require that the server MUST ignore
the flag (unless the kernel folks can better explain what FUA
means for a flush), but until those doc improvements land, the
current nbd.git master was recently changed to reject the flag
with EINVAL (see nbd commit ab22e082), which now makes it
impossible for a qemu client to use FLUSH with an upstream NBD
server.

We should not send FUA with flush unless the upstream protocol
documents what it will do, and even then, it should be something
that the caller can opt into, rather than being unconditional.

53628efbc8 char: fix broken EAGAIN retry on OS-X due to errno clobbering
Some of the chardev I/O paths really want to write the
complete data buffer even though the channel is in
non-blocking mode. To achieve this they look for EAGAIN
and g_usleep() for 100ms. Unfortunately the code is set
to check errno == EAGAIN a second time, after the g_usleep()
call has completed. On OS-X at least, g_usleep clobbers
errno to ETIMEDOUT, causing the retry to be skipped.

This failure to retry means the full data isn't written
to the chardev backend, which causes various failures
including making the tests/ahci-test qtest hang.

Rather than playing games trying to reset errno just
simplify the code to use a goto to retry instead of a
a loop.

340849a9ff util: retry getaddrinfo if getting EAI_BADFLAGS with AI_V4MAPPED
The FreeBSD header files define the AI_V4MAPPED but its
implementation of getaddrinfo() always returns an error
when that flag is set. eg

  address resolution failed for localhost:9000: Invalid value for ai_flags

There are also reports of the same problem on OS-X 10.6

Since AI_V4MAPPED is not critical functionality, if we
get an EAI_BADFLAGS error then just retry without the
AI_V4MAPPED flag set. Use a static var to cache this
status so we don't have to retry on every single call.

Also remove its use from the test suite since it serves
no useful purpose there.

f0707d2e03 checkpatch: add target_ulong to typelist
In some occasions, a patch [1] can start with a hunk containing a
simple type cast. At the time annotate_values() is run, the type is
unknown and the cast type is misinterpreted as a identifier, resulting
in an error if it is followed with a negative value:

	ERROR: spaces required around that '-' (ctx:WxV)

It seems complex to catch all possible types in a cast expression. So,
as a fallback solution, let's add some common qemu types to the
typeList array.

273c515c0a target-i386: do not pass MSR_TSC_AUX to KVM ioctls if CPUID bit is not set
KVM does not let you read or write this MSR if the corresponding CPUID
bit is not set.  This in turn causes MSRs that come after MSR_TSC_AUX
to be ignored by KVM_SET_MSRS.

One visible symptom is that s3.flat from kvm-unit-tests fails with
CPUs that do not have RDTSCP, because the SMBASE is not reset to
0x30000 after reset.

7436268ce7 .travis.yml: make -j3
The move from Travis VMs to Containers came with a upgrade from 1.5
cores to 2. The received wisdom is -j N+1 means a core can be doing work
while other threads wait for IO to complete. This is hard to test on the
Travis infrastructure but an initial before/after eyeballing seems to
confirm it is an improvement.

1d002037f9 .travis.yml: enable OSX builds
Travis has support for OSX builds. Making the setup work cleanly
involves a little hacking about with the .travis.yml file but rather
than make it too messy I've pushed all the "brew" install stuff into a
support script called ./scripts/macosx-brew.sh.

Currently only the default ./configure ${CONFIG} is built as I'm not
sure what extra coverage would come from the other build stanzas.

Three bugfixes for target-ppc, pseries machine type and related devices.
 
 1. Fix a bug in the core code where kvm_vcpu_dirty would not be set
    before the very first system reset.  This meant that if things in
    the reset path did their own cpu_synchronize_state() it would pull
    stale data out of KVM.
 
    On ppc this, in combination with a previous cleanup meant that the
    MSR would be zeroed before entry, instead of correctly having the
    SF (64-bit mode) bit set.
 
 2. Allow immediate detach of hot-added PCI devices which haven't yet
    been announced to the guest.
 
    This fixes a regression: because of a case where we now defer
    announcement of non-zero functions to the guest, an incorrect
    hot-add of such a device can't be backed out until the add is
    completed, which is counter-intuitive to say the least.
 
 3. Fix migration of alternate interrupt locations.  The location of
    interrupt vectors can be affected by the LPCR, and we weren't
    correctly recalculating this after migration of a non-standard LPCR
    value.

76b223200e block: Forbid I/O throttling on nodes with multiple parents for 2.6
As the patches to move I/O throttling to BlockBackend didn't make it in
time for the 2.6 release, but the release adds new ways of configuring
VMs whose behaviour would change once the move is done, we need to
outlaw such configurations temporarily.

The problem exists whenever a BDS has more users than just its BB, for
example it is used as a backing file for another node. (This wasn't
possible in 2.5 yet as we introduced node references to specify a
backing file only recently.) In these cases, the throttling would
apply to these other users now, but after moving throttling to the
BlockBackend the other users wouldn't be throttled any more.

This patch prevents making new references to a throttled node as well as
using monitor commands to throttle a node with multiple parents.

Compared to 2.5 this changes behaviour in some corner cases where
references were allowed before, like bs->file or Quorum children. It
seems reasonable to assume that users didn't use I/O throttling on such
low level nodes. With the upcoming move of throttling into BlockBackend,
such configurations won't be possible anyway.

efdaf797de vl: Move cpu_synchronize_all_states() into qemu_system_reset()
There are currently 3 calls to qemu_system_reset() in vl.c.  Two of them
are immediately preceded by a cpu_synchronize_all_states9) and the
remaining one should be.

The one which doesn't is the very first reset called directly from main().
Without a cpu_synchronize_all_states(), kvm_vcpu_dirty is false at this
point from the earlier cpu_synchronize_all_post_init().  That's incorrect
because the reset path is quite likely to update the CPU state, and that
updated state should be pushed back to KVM, not overwritten with stale
data pushed to KVM immediately after init.

This patch moves the call to cpu_synchronize_all_states() into
qemu_system_reset() for safety, so it is always called.  AFAICT this should
be safe for the handful of callers outside vl.c - these all appear to be in
places where the cpu state is already synchronized so the extra call
will be a no-op.

f40eb921da spapr_drc: enable immediate detach for unsignalled devices
Currently spapr doesn't support "aborting" hotplug of PCI
devices by allowing device_del to immediately remove the
device if we haven't signalled the presence of the device
to the guest.

In the past this wasn't an issue, since we always immediately
signalled device attach and simply relied on full guest-aware
add->remove path for device removal. However, as of 788d259,
we now defer signalling for PCI functions until function 0
is attached, so now we need to deal with these "abort" operations
for cases where a user hotplugs a non-0 function, then opts to
remove it prior hotplugging function 0. Currently they'd have to
reboot before the unplug completed. PCIe multifunction hotplug
does not have this requirement however, so from a management
implementation perspective it would be good to address this within
the same release as 788d259.

We accomplish this by simply adding a 'signalled' flag to track
whether a device hotplug event has been sent to the guest. If it
hasn't, we allow immediate removal under the assumption that the
guest will not be using the device. Devices present at boot/reset
time are also assumed to be 'signalled'.

For CPU/memory/etc, signalling will still happen immediately
as part of device_add, so only PCI functions should be affected.

e24fdd238a target-arm: Correctly reset SCTLR_EL3 for 64-bit CPUs
The regdef for SCTRL_EL3 was incorrectly marked as being an
ARM_CP_ALIAS, with the remark that this was because the 32-bit
definition would take care of reset and migration. However the
intention for banked registers as documented in the comment in
add_cpreg_to_hashtable() is:

 * 2) If ARMv8 is enabled then we can count on a 64-bit version
 *    taking care of the secure bank.  This requires that separate
 *    32 and 64-bit definitions are provided.

and so it marks the 32-bit secure banked version as an alias.
This results in the sctlr_s/sctlr_el[3] field never being reset
or migrated for a 64-bit CPU with EL3 enabled.

Fix this by removing the ARM_CP_ALIAS annotation from SCTLR_EL3.
Since this means it now needs a real reset value, move the regdef
into the same place that we define the 32-bit SCTLR.

  slirp: Fix migration from older versions of QEMU to the current one

eaf136f9a2 slirp: Fix migration from older versions of QEMU to the current one
While adding the IPv6 support, the commit eae303ff23
("slirp: Make Socket structure IPv6 compatible") changed the format of
the migration stream, without taking into account that we might still
receive an old migration stream layout when upgrading from QEMU version
2.5 (or older) to QEMU 2.6. Currently, QEMU bails out when doing a
migration from QEMU 2.5 to the recent master version when it has
been started with a "-net user,guestfwd=..." network. So let's fix
this by checking the version ID of the migration stream and by using
the old behavior if we've detected version 3 or less.
