commit: a0204a5ed091dfe79aced7ec8f3ce1931fd25816
Author: Bernhard Beschow <shentey@gmail.com>
Handling most of smbios data generation in the machine_done notifier is similar
to how the ARM virt machine handles it which also calls smbios_set_defaults()
there. The result is that all pc machines are freed from explicitly worrying
about smbios setup.

default

RH-Commit: [18/18] c7fc6ac7350bca3ff99e58620710a86218385781
JIRA: https://issues.redhat.com/browse/RHEL-21705
Use smbios-entry-point-type='auto' for newer machine types as a workaround
for Windows not detecting SMBIOS tables. Which makes QEMU pick SMBIOS tables
based on configuration (with 2.x preferred and fallback to 3.x if the former
isn't compatible with configuration)
Default compat setting of smbios-entry-point-type after series
for pc/q35 machines:
* 9.0-newer: 'auto'
* 8.1-8.2: '64'
* 8.0-older: '32'

currently smbios_entry_add() preserves internally '-smbios type='
options but tables provided with '-smbios file=' are stored directly
into blob that eventually will be exposed to VM. And then later
QEMU adds default/'-smbios type' entries on top into the same blob.
It makes impossible to generate tables more than once, hence
'immutable' guard was used.
Make it possible to regenerate final blob by storing user provided
blobs into a dedicated area (usr_blobs) and then copy it when
composing final blob. Which also makes handling of -smbios
options consistent.
As side effect of this and previous commits there is no need to
generate legacy smbios_entries at the time options are parsed.
Instead compose smbios_entries on demand from usr_blobs like
it is done for non-legacy SMBIOS tables.

Subject: [PATCH 13/20] smbios: build legacy mode code only for 'pc' machine
RH-Author: Igor Mammedov <imammedo@redhat.com>
RH-MergeRequest: 230: Workaround Windows failing to find 64bit SMBIOS entry point with SeaBIOS
RH-Jira: RHEL-21705
RH-Acked-by: MST <mst@redhat.com>
RH-Acked-by: Ani Sinha <None>
RH-Commit: [11/18] 06e639be03e0d151fb9bcf5f728388edcb84219a
JIRA: https://issues.redhat.com/browse/RHEL-21705
basically moving code around without functional change.
And exposing some symbols so that they could be shared
between smbbios.c and new smbios_legacy.c
plus some meson magic to build smbios_legacy.c only
for 'pc' machine and otherwise replace it with stub
if not selected.
Signed-off-by: Igor Mammedov <imammedo@redhat.com>
Reviewed-by: Ani Sinha <anisinha@redhat.com>
Conflicts: hw/smbios/smbios.c
context change due to downstream smbios_type2_required

handling
RH-Author: Igor Mammedov <imammedo@redhat.com>

RH-Commit: [4/18] a5e09ce1df72293fecad863edd146a8c4b1a734f
JIRA: https://issues.redhat.com/browse/RHEL-21705
smbios_get_tables() bails out right away if leagacy mode is enabled
and won't generate any SMBIOS tables. At the same time x86 specific
fw_cfg_build_smbios() will genarate legacy tables and then proceed
to preparing temporary mem_array for useless call to
smbios_get_tables() and then discard it.
Drop legacy related check in smbios_get_tables() and return from
fw_cfg_build_smbios() early if legacy tables where built without
proceeding to non legacy part of the function.

Subject: [PATCH 10/20] smbios: don't check type4 structures in legacy mode
RH-Author: Igor Mammedov <imammedo@redhat.com>
RH-MergeRequest: 230: Workaround Windows failing to find 64bit SMBIOS entry point with SeaBIOS
RH-Jira: RHEL-21705

RH-Commit: [8/18] c1f8409ea0d916f333c9373535bf21b521c62855
JIRA: https://issues.redhat.com/browse/RHEL-21705
legacy mode doesn't support structures of type 2 and more,
and CLI has a check for '-smbios type' option, however it's
still possible to sneak in type4 as a blob with '-smbios file'
option. However doing the later makes SMBIOS tables broken
since SeaBIOS doesn't expect that.
Rather than trying to add support for type4 to legacy code
(both QEMU and SeaBIOS), simplify smbios_get_table_legacy()
by dropping not relevant check in legacy code and error out
on type4 blob.

If SMBIOS v2 version is requested but number of cores/threads
are more than it's possible to describe with v2, error out
instead of silently ignoring the fact and filling core/thread
count with bogus values.
This will help caller to decide if it should fallback to
SMBIOSv3 when smbios-entry-point-type='auto'

clean up smbios_set_defaults() which is reused by legacy
and non legacy machines from being aware of 'legacy' notion
and need to turn it off. And push legacy handling up to
PC machine code where it's relevant.

RH-Author: Igor Mammedov <imammedo@redhat.com>

RH-Jira: RHEL-21705

RH-Commit: [12/18] d8a5a70602ae0665ce35e5bf87b2d8420f9189bc
JIRA: https://issues.redhat.com/browse/RHEL-21705
Current code uses mix of error_report()+exit(1)
and error_setg() to handle errors.
Use newer error_setg() everywhere, beside consistency
it will allow to detect error condition without killing
QEMU and attempt switch-over to SMBIOS3.x tables/entrypoint
in follow up patch.
while at it, clear smbios_tables pointer after freeing.
that will avoid double free if smbios_get_tables() is called
multiple times.

Subject: [PATCH 18/20] smbios: in case of entry point is 'auto' try to build
v2 tables 1st
RH-Author: Igor Mammedov <imammedo@redhat.com>
RH-MergeRequest: 230: Workaround Windows failing to find 64bit SMBIOS entry point with SeaBIOS

RH-Commit: [16/18] becbcb3d8dad4842e5939bb75e21f4e737a4a325
JIRA: https://issues.redhat.com/browse/RHEL-21705
QEMU for some time now uses SMBIOS 3.0 for PC/Q35 machines by
default, however Windows has a bug in locating SMBIOS 3.0
entrypoint and fails to find tables when booted on SeaBIOS
(on UEFI SMBIOS 3.0 tables work fine since firmware hands
over tables in another way)
Missing SMBIOS tables may lead to some issues for guest
though (worst are: possible reactiveation, inability to
get virtio drivers from 'Windows Update')
It's unclear at this point if MS will fix the issue on their
side. So instead of it (or rather in addition) this patch
will try to workaround the issue.
aka, use smbios-entry-point-type=auto to make QEMU try
generating conservative SMBIOS 2.0 tables and if that
fails (due to limits/requested configuration) fallback
to SMBIOS 3.0 tables.
With this in place majority of users will use SMBIOS 2.0
tables which work fine with (Windows + legacy BIOS).
The configurations that is not to possible to describe
with SMBIOS 2.0 will switch automatically to SMBIOS 3.0
(which will trigger Windows bug but there is nothing
QEMU can do here, so go and aks Microsoft to real fix).

JIRA: https://issues.redhat.com/browse/RHEL-21705
As a preparation to move legacy handling into a separate file,
add prefix 'smbios_' to type0/type1/have_binfile_bitmap/have_fields_bitmap
and expose them in smbios.h so that they can be reused in
legacy and modern code.
Doing it as a separate patch to avoid rename cluttering follow-up
patch which will move legacy code into a separate file.

ui/clipboard: add asserts for update and request
Should an issue like CVE-2023-6683 ever appear again in the future,
it will be more obvious which assumption was violated.

ui/clipboard: mark type as not available when there is no data
With VNC, a client can send a non-extended VNC_MSG_CLIENT_CUT_TEXT
message with len=0. In qemu_clipboard_set_data(), the clipboard info
will be updated setting data to NULL (because g_memdup(data, size)
returns NULL when size is 0). If the client does not set the
VNC_ENCODING_CLIPBOARD_EXT feature when setting up the encodings, then
the 'request' callback for the clipboard peer is not initialized.
Later, because data is NULL, qemu_clipboard_request() can be reached
via vdagent_chr_write() and vdagent_clipboard_recv_request() and
there, the clipboard owner's 'request' callback will be attempted to
be called, but that is a NULL pointer.
In particular, this can happen when using the KRDC (22.12.3) VNC
client.
Another scenario leading to the same issue is with two clients (say
noVNC and KRDC):
The noVNC client sets the extension VNC_FEATURE_CLIPBOARD_EXT and
initializes its cbpeer.
The KRDC client does not, but triggers a vnc_client_cut_text() (note
it's not the _ext variant)). There, a new clipboard info with it as
the 'owner' is created and via qemu_clipboard_set_data() is called,
which in turn calls qemu_clipboard_update() with that info.
In qemu_clipboard_update(), the notifier for the noVNC client will be
called, i.e. vnc_clipboard_notify() and also set vs->cbinfo for the
noVNC client. The 'owner' in that clipboard info is the clipboard peer
for the KRDC client, which did not initialize the 'request' function.
That sounds correct to me, it is the owner of that clipboard info.
Then when noVNC sends a VNC_MSG_CLIENT_CUT_TEXT message (it did set
the VNC_FEATURE_CLIPBOARD_EXT feature correctly, so a check for it
passes), that clipboard info is passed to qemu_clipboard_request() and
the original segfault still happens.
Fix the issue by handling updates with size 0 differently. In
particular, mark in the clipboard info that the type is not available.
While at it, switch to g_memdup2(), because g_memdup() is deprecated.
