05e27d74c7 hw/smbios: add core_count2 to smbios table type 4
In order to use the increased number of cpus, we need to bring smbios
tables in line with the SMBIOS 3.0 specification. This allows us to
introduce core_count2 which acts as a duplicate of core_count if we have
fewer cores than 256, and contains the actual core number per socket if
we have more.

core_enabled2 and thread_count2 fields work the same way.

fd8caa253c hw/smbios: support for type 8 (port connector)
PATCH v1: add support for SMBIOS type 8 to qemu
PATCH v2: incorporate patch v1 feedback and add smbios type=8 to qemu-options

internal_reference: internal reference designator
external_reference: external reference designator
connector_type: hex value for port connector type (see SMBIOS 7.9.2)
port_type: hex value for port type (see SMBIOS 7.9.3)

After studying various vendor implementationsi (Dell, Lenovo, MSI),
the value of internal connector type was hard-coded to 0x0 (None).

Example usage:
-smbios type=8,internal_reference=JUSB1,external_reference=USB1,connector_type=0x12,port_type=0x10 \
-smbios type=8,internal_reference=JAUD1,external_reference="Audio Jack",connector_type=0x1f,port_type=0x1d \
-smbios type=8,internal_reference=LAN,external_reference=Ethernet,connector_type=0x0b,port_type=0x1f \
-smbios type=8,internal_reference=PS2,external_reference=Mouse,connector_type=0x0f,port_type=0x0e \
-smbios type=8,internal_reference=PS2,external_reference=Keyboard,connector_type=0x0f,port_type=0x0d

57e3069641 smbios: sanitize type from external type before checking have_fields_bitmap
test_bit uses header->type as an offset; if the file incorrectly specifies a
type greater than 127, smbios_entry_add will read and write garbage.

To fix this, just pass the smbios data through, assuming the user knows what
to do.  Reported by Coverity as CID 1487255.

cb5fb04fe6 hw/smbios: Add table 4 parameter, "processor-id"
This parameter is to be used in the processor_id entry in the type 4
table.

This parameter is set as optional and if left will use the values from
the CPU model.

This enables hiding the host information from the guest and allowing AMD
VMs to run pretending to be Intel for some userspace software concerns.

63670bd3fc hw/smbios: add assertion to ensure handles of tables 19 and 32 do not collide
Since change dcf359832eec02 ("hw/smbios: fix table memory corruption with large memory vms")
we reserve additional space between handle numbers of tables 17 and 19 for
large VMs. This may cause table 19 to collide with table 32 in their handle
numbers for those large VMs. This change adds an assertion to ensure numbers
do not collide. If they do, qemu crashes with useful debug information for
taking additional steps.

a379d4550c hw/smbios: fix overlapping table handle numbers with large memory vms
The current smbios table implementation splits the main memory in 16 GiB
(DIMM like) chunks. With the current smbios table assignment code, we can have
only 512 such chunks before the 16 bit handle numbers in the header for tables
17 and 19 conflict. A guest with more than 8 TiB of memory will hit this
limitation and would fail with the following assertion in isa-debugcon:

ASSERT_EFI_ERROR (Status = Already started)
ASSERT /builddir/build/BUILD/edk2-ca407c7246bf/OvmfPkg/SmbiosPlatformDxe/SmbiosPlatformDxe.c(125): !EFI_ERROR (Status)

This change adds an additional offset between tables 17 and 19 handle numbers
when configuring VMs larger than 8 TiB of memory. The value of the offset is
calculated to be equal to the additional space required to be reserved
in order to accomodate more DIMM entries without the table handles colliding.
In normal cases where the VM memory is smaller or equal to 8 TiB, this offset
value is 0. Hence in this case, no additional handle numbers are reserved and
table handle values remain as before.

Since smbios memory is not transmitted over the wire during migration,
this change can break migration for large memory vms if the guest is in the
middle of generating the tables during migration. However, in those
situations, qemu generates invalid table handles anyway with or without this
fix. Hence, we do not preserve the old bug by introducing compat knobs/machine
types.

10be11d0b4 smbios: Rename SMBIOS_ENTRY_POINT_* enums
Rename the enums to match the naming style used by QAPI, and to
use "32" and "64" instead of "20" and "31".  This will allow us
to more easily move the enum to the QAPI schema later.

About the naming choice: "SMBIOS 2.1 entry point"/"SMBIOS 3.0
entry point" and "32-bit entry point"/"64-bit entry point" are
synonymous in the SMBIOS specification.  However, the phrases
"32-bit entry point" and "64-bit entry point" are used more often.

The new names also avoid confusion between the entry point format
and the actual SMBIOS version reported in the entry point
structure.  For example: currently the 32-bit entry point
actually report SMBIOS 2.8 support, not 2.1.

Based on portions of a patch submitted by Daniel P. Berrangé.

05dfb447a4 hw/smbios: support for type 41 (onboard devices extended information)
Type 41 defines the attributes of devices that are onboard. The
original intent was to imply the BIOS had some level of control over
the enablement of the associated devices.

If network devices are present in this table, by default, udev will
name the corresponding interfaces enoX, X being the instance number.
Without such information, udev will fallback to using the PCI ID and
this usually gives ens3 or ens4. This can be a bit annoying as the
name of the network card may depend on the order of options and may
change if a new PCI device is added earlier on the commande line.
Being able to provide SMBIOS type 41 entry ensure the name of the
interface won't change and helps the user guess the right name without
booting a first time.

This can be invoked with:

    $QEMU -netdev user,id=internet
          -device virtio-net-pci,mac=50:54:00:00:00:42,netdev=internet,id=internet-dev \
          -smbios type=41,designation='Onboard LAN',instance=1,kind=ethernet,pcidev=internet-dev

The PCI segment is assumed to be 0. This should hold true for most
cases.

10c3666658 hw/smbios: report error if table size is too large
The SMBIOS 2.1 entry point uses a uint16 data type for reporting the
total length of the tables. If the user passes -smbios configuration to
QEMU that causes the table size to exceed this limit then various bad
behaviours result, including

 - firmware hangs in an infinite loop
 - firmware triggers a KVM crash on bad memory access
 - firmware silently discards user's SMBIOS data replacing it with
   a generic data set.

Limiting the size to 0xffff in QEMU avoids triggering most of these
problems. There is a remaining bug in SeaBIOS which tries to prepend its
own data for table 0, and does not check whether there is sufficient
space before attempting this.

c906e03909 hw/smbios: add options for type 4 max-speed and current-speed
Common VM users sometimes care about CPU speed, so we add two new
options to allow VM vendors to present CPU speed to their users.
Normally these information can be fetched from host smbios.

Strictly speaking, the "max speed" and "current speed" in type 4
are not really for the max speed and current speed of processor, for
"max speed" identifies a capability of the system, and "current speed"
identifies the processor's speed at boot (see smbios spec), but some
applications do not tell the differences.

Not exactly elegant, I'm afraid.

The "when != lbl:" is necessary to avoid transforming

         if (fun(args, &err)) {
             goto out
         }
         ...
     out:
         error_propagate(errp, err);

even though other paths to label out still need the error_propagate().
For an actual example, see sclp_realize().

Without the "when strict", Coccinelle transforms vfio_msix_setup(),
incorrectly.  I don't know what exactly "when strict" does, only that
it helps here.

The match of return is narrower than what I want, but I can't figure
out how to express "return where the operand doesn't use @err".  For
an example where it's too narrow, see vfio_intx_enable().

Silently fails to convert hw/arm/armsse.c, because Coccinelle gets
confused by ARMSSE being used both as typedef and function-like macro
there.  Converted manually.

Line breaks tidied up manually.  One nested declaration of @local_err
deleted manually.  Preexisting unwanted blank line dropped in
hw/riscv/sifive_e.c.

b81a5f9427 hw/smbios: fix offset of type 3 sku field
The type 3 SMBIOS structure[1] ends with fields

  ...
  0x14  - contained element count
  0x15  - contained element record length
  0x16  - sku number

The smbios_type_3 struct missed the contained element record
length field, causing sku number to be reported at the wrong
offset.

1028283c60 smbios: Clean up error handling in smbios_add()
Calling error_report() in a function that takes an Error ** argument
is suspicious.  smbios_entry_add() does that, and then exit()s.  It
also passes &error_fatal to qemu_opts_validate().  Both wrong, but

While there, drop superfluous includes of both headers, and

2d6dcbf93f smbios: support setting OEM strings table
The cloud-init program currently allows fetching of its data by repurposing of
the 'system' type 'serial' field. This is a clear abuse of the serial field that
would clash with other valid usage a virt management app might have for that
field.

Fortunately the SMBIOS defines an "OEM Strings" table whose puporse is to allow
exposing of arbitrary vendor specific strings to the operating system. This is
perfect for use with cloud-init, or as a way to pass arguments to OS installers
such as anaconda.

This patch makes it easier to support this with QEMU. e.g.

  $QEMU -smbios type=11,value=Hello,value=World,value=Tricky,,value=test

Which results in the guest seeing dmidecode data

  Handle 0x0E00, DMI type 11, 5 bytes
  OEM Strings
          String 1: Hello
          String 2: World
          String 3: Tricky,value=test

It is suggested that any app wanting to make use of this OEM strings capability
for accepting data from the host mgmt layer should use its name as a string
prefix. e.g. to expose OEM strings targetting both cloud init and anaconda in
parallel the mgmt app could set

  $QEMU -smbios type=11,value=cloud-init:ds=nocloud-net;s=http://10.10.0.1:8000/,\
        value=anaconda:method=http://dl.fedoraproject.org/pub/fedora/linux/releases/25/x86_64/os

which would appear as

  Handle 0x0E00, DMI type 11, 5 bytes
  OEM Strings
          String 1: cloud-init:ds=nocloud-net;s=http://10.10.0.1:8000/
          String 2: anaconda:method=http://dl.fedoraproject.org/pub/fedora/linux/releases/25/x86_64/os

Use of such string prefixes means the app won't have to care which string slot
its data appears in.

cea25275a3 util: Add UUID API
A number of different places across the code base use CONFIG_UUID. Some
of them are soft dependency, some are not built if libuuid is not
available, some come with dummy fallback, some throws runtime error.

It is hard to maintain, and hard to reason for users.

Since UUID is a simple standard with only a small number of operations,
it is cleaner to have a central support in libqemuutil. This patch adds
qemu_uuid_* functions that all uuid users in the code base can
rely on. Except for qemu_uuid_generate which is new code, all other
functions are just copy from existing fallbacks from other files.

Note that qemu_uuid_parse is moved without updating the function
signature to use QemuUUID, to keep this patch simple.

da34e65cb4 include/qemu/osdep.h: Don't include qapi/error.h
Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the
Error typedef.  Since then, we've moved to include qemu/osdep.h
everywhere.  Its file comment explains: "To avoid getting into
possible circular include dependencies, this file should not include
any other QEMU headers, with the exceptions of config-host.h,
compiler.h, os-posix.h and os-win32.h, all of which are doing a
similar job to this file and are under similar constraints."
qapi/error.h doesn't do a similar job, and it doesn't adhere to
similar constraints: it includes qapi-types.h.  That's in excess of
100KiB of crap most .c files don't actually need.

Add the typedef to qemu/typedefs.h, and include that instead of
qapi/error.h.  Include qapi/error.h in .c files that need it and don't
get it now.  Include qapi-types.h in qom/object.h for uint16List.

Update scripts/clean-includes accordingly.  Update it further to match
reality: replace config.h by config-target.h, add sysemu/os-posix.h,
sysemu/os-win32.h.  Update the list of includes in the qemu/osdep.h
comment quoted above similarly.

This reduces the number of objects depending on qapi/error.h from "all
of them" to less than a third.  Unfortunately, the number depending on
qapi-types.h shrinks only a little.  More work is needed for that one.
