63d3145aad fw_cfg: Adopt /opt/RFQDN convention
FW CFG's primary user is QEMU, which uses it to expose configuration
information (in the widest sense) to Firmware.  Thus the name FW CFG.

FW CFG can also be used by others for their own purposes.  QEMU is
merely acting as transport then.  Names starting with opt/ are
reserved for such uses.  There is no provision, however, to guide safe
sharing among different such users.

Fix that, loosely following QMP precedence: names should start with
opt/RFQDN/, where RFQDN is a reverse fully qualified domain name you
control.

Based on a more ambitious patch from Michael Tsirkin.

5eb0b194e9 cadence_uart: bounds check write offset
cadence_uart_init() initializes an I/O memory region of size 0x1000
bytes.  However in uart_write(), the 'offset' parameter (offset within
region) is divided by 4 and then used to index the array 'r' of size
CADENCE_UART_R_MAX which is much smaller: (0x48/4).  If 'offset>>=2'
exceeds CADENCE_UART_R_MAX, this will cause an out-of-bounds memory
write where the offset and the value are controlled by guest.

This will corrupt QEMU memory, in most situations this causes the vm to
crash.

Fix by checking the offset against the array size.

1ae3f2f178 ehci: apply limit to iTD/sidt descriptors
Commit "156a2e4 ehci: make idt processing more robust" tries to avoid a
DoS by the guest (create a circular iTD queue and let qemu ehci
emulation run in circles forever).  Unfortunately this has two problems:
First it misses the case of siTDs, and second it reportedly breaks
FreeBSD.

So lets go for a different approach: just count the number of iTDs and
siTDs we have seen per frame and apply a limit.  That should really
catch all cases now.

ed3d807b0a cuda: fix off-by-one error in SET_TIME command
With the new framework the cuda_cmd_set_time command directly receive
the data, without the command byte. Therefore the time is stored at
in_data[0], not at in_data[1].

This fixes the "hwclock --systohc" command in a guest.

9997cf7bda target-i386: Set AMD alias bits after filtering CPUID data
QEMU complains about -cpu host on an AMD machine:
  warning: host doesn't support requested feature: CPUID.80000001H:EDX [bit 0]
For bits 0,1,3,4,5,6,7,8,9,12,13,14,15,16,17,23,24.

KVM_GET_SUPPORTED_CPUID and and x86_cpu_get_migratable_flags()
don't handle the AMD CPUID aliases bits, making
x86_cpu_filter_features() print warnings and clear those CPUID
bits incorrectly.

To avoid hacking x86_cpu_get_migratable_flags() to handle
CPUID_EXT2_AMD_ALIASES (just like the existing hack inside
kvm_arch_get_supported_cpuid()), simply move the
CPUID_EXT2_AMD_ALIASES code in x86_cpu_realizefn() after the
x86_cpu_filter_features() call.

This will probably make the CPUID_EXT2_AMD_ALIASES hack in
kvm_arch_get_supported_cpuid() unnecessary, too. The hack will be
removed in a follow-up patch after v2.6.0.

Some refactorings and design questions will still intersect, but review

aa378598fe ppc: Fix migration of the XER register
env->xer only holds the lower bits of the XER register nowadays, the
SO, OV and CA bits are stored in separate variables (see the function
cpu_write_xer() for details). Since the migration code currently only
reads the "xer" variable, the upper bits are lost during migration.
Fix it by using cpu_read_xer() instead.

537d3e8e6b ppc: Fix the bad exception NIP value and the range check in LSWX
The range checks in the LSWX instruction are completely insufficient:
They do not take the wrap-around case into account, and the check
"reg < rx" should be "reg <= rx" instead. Fix it by using the new
lsw_reg_in_range() helper function that is already used for LSWI, too.

Then there is a second problem: In case the INVAL exception is generated,
the NIP value is wrong, it currently points to the instruction before
the LSWX instruction. This is because gen_lswx() already decreases the
NIP value by 4 (to be prepared for page fault exceptions), and
powerpc_excp() later decreases it again by 4 while handling the program
exception. So to get this right, we've got to undo the "- 4" from
gen_lswx() here before calling helper_raise_exception_err().

afbee7128c ppc: Fix the range check in the LSWI instruction
There are two issues: First, the number of registers that are used has
to be calculated with "(nb + 3) / 4" (i.e. round always up, not down).
Second, the "start <= ra && (start + nr - 32) > ra" condition for the
wrap-around case is wrong: It has to be tested with "||" instead of "&&".
Since we can reuse this check later for the LSWX instruction, let's
place the fixed code into a helper function, too.

The cacheflush system call (found on MIPS and ARM) has been included in
the libseccomp header since 2.2.0, so include it back to that version.
Previously it was only enabled since 2.2.3 since that is when it was
enabled properly for ARM.

This will allow seccomp support to be enabled for MIPS back to
libseccomp 2.2.0.

d1129a8ad9 nbd: Don't kill server on client that doesn't request TLS
Upstream NBD documents (as of commit 4feebc95) that servers MAY
choose to operate in a conditional mode, where it is up to the
client whether to use TLS.  For qemu's case, we want to always be
in FORCEDTLS mode, because of the risk of man-in-the-middle
attacks, and since we never export more than one device; likewise,
the qemu client will ALWAYS send NBD_OPT_STARTTLS as its first
option.  But now that SELECTIVETLS servers exist, it is feasible
to encounter a (non-qemu) client that is programmed to talk to
such a server, and does not do NBD_OPT_STARTTLS first, but rather
wants to probe if it can use a non-encrypted export.

The NBD protocol documents that we should let such a client
continue trying, on the grounds that maybe the client will get the
hint to send NBD_OPT_STARTTLS, rather than immediately dropping
the connection.

Note that NBD_OPT_EXPORT_NAME is a special case: since it is the
only option request that can't have an error return, we have to
(continue to) drop the connection on that one; rather, what we are
fixing here is that all other replies prior to TLS initiation tell
the client NBD_REP_ERR_TLS_REQD, but keep the connection alive.

23994a5f52 nbd: fix assert() on qemu-nbd stop
From time to time qemu-nbd is crashing on the following assert:
    assert(state == TERMINATING);
    nbd_export_closed
    nbd_export_put
    main
and the state at the moment of the crash is evaluated to TERMINATE.

During shutdown process of the client the nbd_client_thread thread sends
SIGTERM signal and the main thread calls the nbd_client_closed callback.
If the SIGTERM callback will be executed after change the state to
TERMINATING, then the state will once again be TERMINATE.

To solve the issue, we must change the state to TERMINATE only if the state
is RUNNING. In the other case we are shutting down already.

200650d49f nbd: Don't fail handshake on NBD_OPT_LIST descriptions
The NBD Protocol states that NBD_REP_SERVER may set
'length > sizeof(namelen) + namelen'; in which case the rest
of the packet is a UTF-8 description of the export.  While we
don't know of any NBD servers that send this description yet,
we had better consume the data so we don't choke when we start
to talk to such a server.

Also, a (buggy/malicious) server that replies with length <
sizeof(namelen) would cause us to block waiting for bytes that
the server is not sending, and one that replies with super-huge
lengths could cause us to temporarily allocate up to 4G memory.
Sanity check things before blindly reading incorrectly.

with the assert:

bdrv_co_do_pwritev: Assertion `!(bs->open_flags & 0x0800)' failed.

This avoids the problem by delaying the pflash update until after

  Migrating Q35/EFI vm.
  Changing efi variable content (with efiboot in the guest)

16aaf975ee block: Don't ignore flags in blk_{,co,aio}_write_zeroes()
Commit 57d6a428 neglected to pass the given flags to blk_aio_prwv(),
which broke discard by WRITE SAME for scsi-disk (the UNMAP bit would be
ignored).

Commit fc1453cd introduced the same bug for blk_write_zeroes(). This is
used for 'qemu-img convert' without has_zero_init (e.g. on a block
device) and for preallocation=falloc in parallels.

Commit 8896e088 is the version for blk_co_write_zeroes(). This function
is only used in qemu-io.

66176fc6a7 block/vpc: make checks on max table size a bit more lax
The check on the max_table_size field not being larger than required is
valid, and in accordance with the VHD spec.  However, there have been
VHD images encountered in the wild that have an out-of-spec max table
size that is technically too large.

There is no issue in allowing this larger table size, as we also
later verify that the computed size (used for the pagetable) is
large enough to fit all sectors.  In addition, max_table_entries
is bounds checked against SIZE_MAX and INT_MAX.

Remove the strict check, so that we can accomodate these sorts of
images that are benignly out of spec.

c23fb11bbb block/vpc: Use the correct max sector count for VHD images
The old VHD_MAX_SECTORS value is incorrect, and is a throwback
to the CHS calculations.  The VHD specification allows images up to 2040
GiB, which (using 512 byte sectors) corresponds to a maximum number of
sectors of 0xff000000, rather than the old value of 0xfe0001ff.

Update VHD_MAX_SECTORS to reflect the correct value.

Also, update comment references to the actual size limit, and correct
one compare so that we can have sizes up to the limit.

9bdfb9e8ac vpc: use current_size field for XenServer VHD images
The vpc driver has two methods of determining virtual disk size.  The
correct one to use depends on the software that generated the image
file.  Add the XenServer creator_app signature so that image size is
correctly detected for those images.

7fa84cd8d4 block: Fix blk_aio_write_zeroes()
Commit 57d6a428 broke blk_aio_write_zeroes() because in some write
functions in the call path don't have an explicit length argument but
reuse qiov->size instead. Which is great, except that write_zeroes
doesn't have a qiov, which this commit interprets as 0 bytes.
Consequently, blk_aio_write_zeroes() didn't effectively do anything.

This patch introduces an explicit acb->bytes in BlkAioEmAIOCB and uses
that instead of acb->rwco.size.

The synchronous version of the function is okay because it does pass a
qiov (with the right size and a NULL pointer as its base).
