83bee4b51f crypto: replace 'des-rfb' cipher with 'des'
Currently the crypto layer exposes support for a 'des-rfb'
algorithm which is just normal single-DES, with the bits
in each key byte reversed. This special key munging is
required by the RFB protocol password authentication
mechanism.

Since the crypto layer is generic shared code, it makes
more sense to do the key byte munging in the VNC server
code, and expose normal single-DES support.

Replacing cipher 'des-rfb' by 'des' looks like an incompatible
interface change, but it doesn't matter.  While the QMP schema
allows any QCryptoCipherAlgorithm for the 'cipher-alg' field
in QCryptoBlockCreateOptionsLUKS, the code restricts what can
be used at runtime. Thus the only effect is a change in error
message.

Original behaviour:

 $ qemu-img create -f luks --object secret,id=sec0,data=123 -o cipher-alg=des-rfb,key-secret=sec0 demo.luks 1G
 Formatting 'demo.luks', fmt=luks size=1073741824 key-secret=sec0 cipher-alg=des-rfb
 qemu-img: demo.luks: Algorithm 'des-rfb' not supported

New behaviour:

 $ qemu-img create -f luks --object secret,id=sec0,data=123 -o cipher-alg=des-rfb,key-secret=sec0 demo.luks 1G
 Formatting 'demo.luks', fmt=luks size=1073741824 key-secret=sec0 cipher-alg=des-fish
 qemu-img: demo.luks: Invalid parameter 'des-rfb'

6801404429 crypto: delete built-in XTS cipher mode support
The built-in AES+XTS implementation is used for the LUKS encryption
When building system emulators it is reasonable to expect that an
external crypto library is being used instead. The performance of the
builtin XTS implementation is terrible as it has no CPU acceleration
support. It is thus not worth keeping a home grown XTS implementation
for the built-in cipher backend.

f8157e100c crypto: add crypto tests for single block DES-ECB and DES-CBC
The GNUTLS crypto provider doesn't support DES-ECB, only DES-CBC.
We can use the latter to simulate the former, if we encrypt only
1 block (8 bytes) of data at a time, using an all-zeros IV. This
is a very inefficient way to use the QCryptoCipher APIs, but
since the VNC authentication challenge is only 16 bytes, this
is acceptable. No other part of QEMU should be using DES. This
test case demonstrates the equivalence of ECB and CBC for the
single-block case.

63268c4970 migration: Move bitmap_mutex out of migration_bitmap_clear_dirty()
Taking the mutex every time for each dirty bit to clear is too slow, especially
we'll take/release even if the dirty bit is cleared.  So far it's only used to
sync with special cases with qemu_guest_free_page_hint() against migration
thread, nothing really that serious yet.  Let's move the lock to be upper.

There're two callers of migration_bitmap_clear_dirty().

For migration, move it into ram_save_iterate().  With the help of MAX_WAIT
logic, we'll only run ram_save_iterate() for no more than 50ms-ish time, so
taking the lock once there at the entry.  It also means any call sites to
qemu_guest_free_page_hint() can be delayed; but it should be very rare, only
during migration, and I don't see a problem with it.

For COLO, move it up to colo_flush_ram_cache().  I think COLO forgot to take
that lock even when calling ramblock_sync_dirty_bitmap(), where another example
is migration_bitmap_sync() who took it right.  So let the mutex cover both the
ramblock_sync_dirty_bitmap() and migration_bitmap_clear_dirty() calls.

It's even possible to drop the lock so we use atomic operations upon rb->bmap
and the variable migration_dirty_pages.  I didn't do it just to still be safe,
also not predictable whether the frequent atomic ops could bring overhead too
e.g. on huge vms when it happens very often.  When that really comes, we can
keep a local counter and periodically call atomic ops.  Keep it simple for now.

ca7bd0821b migration: Clear error at entry of migrate_fd_connect()
For each "migrate" command, remember to clear the s->error before going on.
For one reason, when there's a new error it'll be still remembered; see
migrate_set_error() who only sets the error if error==NULL.  Meanwhile if a
failed migration completes (e.g., postcopy recovered and finished), we
shouldn't dump an error when calling migrate_fd_cleanup() at last.

ca30f24d12 migration: Don't do migrate cleanup if during postcopy resume
Below process could crash qemu with postcopy recovery:

  1. (hmp) migrate -d ..
  2. (hmp) migrate_start_postcopy
  3. [network down, postcopy paused]
  4. (hmp) migrate -r $WRONG_PORT
     when try the recover on an invalid $WRONG_PORT, cleanup_bh will be cleared
  5. (hmp) migrate -r $RIGHT_PORT
     [qemu crash on assert(cleanup_bh)]

The thing is we shouldn't cleanup if it's postcopy resume; the error is set
mostly because the channel is wrong, so we return directly waiting for the user
to retry.

migrate_fd_cleanup() should only be called when migration is cancelled or
completed.

2e3e3da3c2 migration: Release return path early for paused postcopy
When postcopy pause triggered, we rely on the migration thread to cleanup the
to_dst_file handle, and the return path thread to cleanup the from_dst_file
handle (which is stored in the local variable "rp").

Within the process, from_dst_file cleanup (qemu_fclose) is postponed until it's
setup again due to a postcopy recovery.

It used to work before yank was born; after yank is introduced we rely on the
refcount of IOC to correctly unregister yank function in channel_close().  If
without the early and on-time release of from_dst_file handle the yank function
will be leftover during paused postcopy.

Without this patch, below steps (quoted from Xiaohui) could trigger qemu src
crash:

  1.Boot vm on src host
  2.Boot vm on dst host
  3.Enable postcopy on src&dst host
  4.Load stressapptest in vm and set postcopy speed to 50M
  5.Start migration from src to dst host, change into postcopy mode when migration is active.
  6.When postcopy is active, down the network card(do migration via this network) on dst host.
  7.Wait untill postcopy is paused on src&dst host.
  8.Before up network card, recover migration on dst host, will get error like following.
  9.Ignore the error of step 8, go on recovering migration on src host:

  After step 9, qemu on src host will core dump after some seconds:
  qemu-kvm: ../util/yank.c:107: yank_unregister_instance: Assertion `QLIST_EMPTY(&entry->yankfns)' failed.
  1.sh: line 38: 44662 Aborted                 (core dumped)

294aa0437b numa: Parse initiator= attribute before cpus= attribute
When parsing cpus= attribute of -numa object couple of checks
is performed, such as correct initiator setting (see the if()
statement at the end of for() loop in
machine_set_cpu_numa_node()).

However, with the current code cpus= attribute is parsed before
initiator= attribute and thus the check may fail even though it
is not obvious why. But since parsing the initiator= attribute
does not depend on the cpus= attribute we can swap the order of
the two.

It's fairly easy to reproduce with the following command line
(snippet of an actual cmd line):

  -smp 4,sockets=4,cores=1,threads=1 \
  -object '{"qom-type":"memory-backend-ram","id":"ram-node0","size":2147483648}' \
  -numa node,nodeid=0,cpus=0-1,initiator=0,memdev=ram-node0 \
  -object '{"qom-type":"memory-backend-ram","id":"ram-node1","size":2147483648}' \
  -numa node,nodeid=1,cpus=2-3,initiator=1,memdev=ram-node1 \
  -numa hmat-lb,initiator=0,target=0,hierarchy=memory,data-type=access-latency,latency=5 \
  -numa hmat-lb,initiator=0,target=0,hierarchy=first-level,data-type=access-latency,latency=10 \
  -numa hmat-lb,initiator=1,target=1,hierarchy=memory,data-type=access-latency,latency=5 \
  -numa hmat-lb,initiator=1,target=1,hierarchy=first-level,data-type=access-latency,latency=10 \
  -numa hmat-lb,initiator=0,target=0,hierarchy=memory,data-type=access-bandwidth,bandwidth=204800K \
  -numa hmat-lb,initiator=0,target=0,hierarchy=first-level,data-type=access-bandwidth,bandwidth=208896K \
  -numa hmat-lb,initiator=1,target=1,hierarchy=memory,data-type=access-bandwidth,bandwidth=204800K \
  -numa hmat-lb,initiator=1,target=1,hierarchy=first-level,data-type=access-bandwidth,bandwidth=208896K \

f74d339c86 numa: Report expected initiator
When setting up NUMA with HMAT enabled there's a check performed
in machine_set_cpu_numa_node() that reports an error when a NUMA
node has a CPU but the node's initiator is not itself. The error
message reported contains only the expected value and not the
actual value (which is different because an error is being
reported). Report both values in the error message.

a7a0da844d target/i386: suppress CPUID leaves not defined by the CPU vendor
Currently all built-in CPUs report cache information via CPUID leaves 2
and 4, but these have never been defined for AMD. In the case of
SEV-SNP this can cause issues with CPUID enforcement. Address this by
allowing CPU types to suppress these via a new "x-vendor-cpuid-only"
CPU property, which is true by default, but switched off for older
machine types to maintain compatibility.

cce087f628 i386: Hyper-V SynIC requires POST_MESSAGES/SIGNAL_EVENTS privileges
When Hyper-V SynIC is enabled, we may need to allow Windows guests to make
hypercalls (POST_MESSAGES/SIGNAL_EVENTS). No issue is currently observed
because KVM is very permissive, allowing these hypercalls regarding of

b26f68c36b i386: HV_HYPERCALL_AVAILABLE privilege bit is always needed
According to TLFS, Hyper-V guest is supposed to check
HV_HYPERCALL_AVAILABLE privilege bit before accessing
HV_X64_MSR_GUEST_OS_ID/HV_X64_MSR_HYPERCALL MSRs but at least some
Windows versions ignore that. As KVM is very permissive and allows
accessing these MSRs unconditionally, no issue is observed. We may,
however, want to tighten the checks eventually. Conforming to the
spec is probably also a good idea.

Enable HV_HYPERCALL_AVAILABLE bit unconditionally.

5ce48fa354 i386: kill off hv_cpuid_check_and_set()
hv_cpuid_check_and_set() does too much:
- Checks if the feature is supported by KVM;
- Checks if all dependencies are enabled;
- Sets the feature bit in cpu->hyperv_features for 'passthrough' mode.

To reduce the complexity, move all the logic except for dependencies
check out of it. Also, in 'passthrough' mode we don't really need to
check dependencies because KVM is supposed to provide a consistent
set anyway.

071ce4b03b i386: expand Hyper-V features during CPU feature expansion time
To make Hyper-V features appear in e.g. QMP query-cpu-model-expansion we
need to expand and set the corresponding CPUID leaves early. Modify
x86_cpu_get_supported_feature_word() to call newly intoduced Hyper-V
specific kvm_hv_get_supported_cpuid() instead of
kvm_arch_get_supported_cpuid(). We can't use kvm_arch_get_supported_cpuid()
as Hyper-V specific CPUID leaves intersect with KVM's.

Note, early expansion will only happen when KVM supports system wide
KVM_GET_SUPPORTED_HV_CPUID ioctl (KVM_CAP_SYS_HYPERV_CPUID).

07454e2ea8 i386: hardcode supported eVMCS version to '1'
Currently, the only eVMCS version, supported by KVM (and described in TLFS)
is '1'. When Enlightened VMCS feature is enabled, QEMU takes the supported
eVMCS version range (from KVM_CAP_HYPERV_ENLIGHTENED_VMCS enablement) and
puts it to guest visible CPUIDs. When (and if) eVMCS ver.2 appears a
problem on migration is expected: it doesn't seem to be possible to migrate
from a host supporting eVMCS ver.2 to a host, which only support eVMCS
ver.1.

Hardcode eVMCS ver.1 as the result of 'hv-evmcs' enablement for now. Newer
eVMCS versions will have to have their own enablement options (e.g.
'hv-evmcs=2').

Linux needs setprop to fix up the device tree, otherwise it's not
finding devices and cannot boot. Since recent VOF change now we need
to add a callback to allow this which is what this patch does.

c093364f4d fd-trans: Fix race condition on reallocation of the translation table.
The mapping from file-descriptors to translator functions is not guarded
on realloc which may cause invalid function pointers to be read from a

3ffe3268ea linux-user: Simplify host <-> target errno conversion using macros
Convert the host_to_target_errno_table[] array to a switch
case to allow compiler optimizations (such noticing the identity
function when host and guest errnos match). Extract the errnos
list as to a new includible unit, using a generic macro. Remove
the code related to target_to_host_errno_table[] initialization.

8f968b6a24 linux-user: Extract target errno to 'target_errno_defs.h'
We want to access the target errno indepently of the rest of the
linux-user code. Move the header containing the generic errno
definitions ('errno_defs.h') to 'generic/target_errno_defs.h',
create a new 'target_errno_defs.h' in each target which itself
includes 'generic/target_errno_defs.h'.
