Do not allocate env->nested_state unless we later need to migrate the
nested virtualization state.
With this change, nested_state_needed() will return false if the
VMX flag is not included in the virtual machine. KVM_GET/SET_NESTED_STATE
is also disabled for SVM which is safer (we know that at least the NPT
root and paging mode have to be saved/loaded), and thus the corresponding
subsection can go away as well.
Inspired by a patch from Liran Alon.
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
Previous to this change, a vCPU exposed with VMX running on a kernel
without KVM_CAP_NESTED_STATE or KVM_CAP_EXCEPTION_PAYLOAD resulted in
adding a migration blocker. This was because when the code was written
it was thought there is no way to reliably know if a vCPU is utilising
VMX or not at runtime. However, it turns out that this can be known to
some extent:
In order for a vCPU to enter VMX operation it must have CR4.VMXE set.
Since it was set, CR4.VMXE must remain set as long as the vCPU is in
VMX operation. This is because CR4.VMXE is one of the bits set
in MSR_IA32_VMX_CR4_FIXED1.
There is one exception to the above statement when vCPU enters SMM mode.
When a vCPU enters SMM mode, it temporarily exits VMX operation and
may also reset CR4.VMXE during execution in SMM mode.
When the vCPU exits SMM mode, vCPU state is restored to be in VMX operation
and CR4.VMXE is restored to its original state of being set.
Therefore, when the vCPU is not in SMM mode, we can infer whether
VMX is being used by examining CR4.VMXE. Otherwise, we cannot
know for certain but assume the worse that vCPU may utilise VMX.
Summaring all the above, a vCPU may have enabled VMX in case
CR4.VMXE is set or vCPU is in SMM mode.
Therefore, remove migration blocker and check before migration
(cpu_pre_save()) if the vCPU may have enabled VMX. If true, only then
require relevant kernel capabilities.
While at it, demand KVM_CAP_EXCEPTION_PAYLOAD only when the vCPU is in
guest-mode and there is a pending/injected exception. Otherwise, this
kernel capability is not required for proper migration.

A supposed exploit of QEMU was recently announced as CVE-2019-12928
claiming that the monitor console was insecure because the "migrate"
command enabled arbitrary command execution for a remote attacker.
To be a security risk the user launching QEMU must have configured
the monitor in a way that allows for other users to access it. The
exploit report quoted use of the "tcp" character device backend for
QMP.
This would indeed allow any network user to connect to QEMU and
execute arbitrary commands, however, this is not a flaw in QEMU.
It is the normal expected behaviour of the monitor console and the
commands it supports. Given a monitor connection, there are many
ways to access host file system content besides the migrate command.
The reality is that the monitor console (whether QMP or HMP) is
considered a privileged interface to QEMU and as such must only
be made available to trusted users. IOW, making it available with
no authentication over TCP is simply a, very serious, user
configuration error not a security flaw in QEMU itself.
The one thing this bogus security report highlights though is that
we have not clearly documented the security implications around the
use of the monitor. Add a few paragraphs of text to the security
docs explaining why the monitor is a privileged interface and making
a recommendation to only use the UNIX socket character device backend.

Only the emulators link to code that uses capstone, so adding it to the
global LIBs places undesirable dependancies on other binaries, in
particular the tools.
There is no variable that covers both user emulation and machine
emulation, so add a new "$libs_cpu" for this purpose.
In particular this removes the 8 MB capstone dep from the things
qemu-img links against, allowing for a more minimal installation
in scenarios that don't want system emulators installed.

Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
The SIOCGSTAMP symbol was previously defined in the
asm-generic/sockios.h header file. QEMU sees that header
indirectly via sys/socket.h
In linux kernel commit 0768e17073dc527ccd18ed5f96ce85f9985e9115
the asm-generic/sockios.h header no longer defines SIOCGSTAMP.
Instead it provides only SIOCGSTAMP_OLD, which only uses a
32-bit time_t on 32-bit architectures.
The linux/sockios.h header then defines SIOCGSTAMP using
either SIOCGSTAMP_OLD or SIOCGSTAMP_NEW as appropriate. If
SIOCGSTAMP_NEW is used, then the tv_sec field is 64-bit even
on 32-bit architectures
To cope with this we must now convert the old and new type from
the target to the host one.

OpenSBI (https://github.com/riscv/opensbi) aims to provide an open-source
reference implementation of the RISC-V Supervisor Binary Interface (SBI)
specifications for platform-specific firmwares executing in M-mode. For all
supported platforms, OpenSBI provides several runtime firmware examples.
These example firmwares can be used to replace the legacy riscv-pk bootloader
and enable the use of well-known bootloaders such as U-Boot.
OpenSBI is distributed under the terms of the BSD 2-clause license

In this case all of the code we are using from OpenSBI is BSD 2-clause
as we aren't using the Kendryte code (Apache-2.0) with QEMU and libfdt
is dual licensed as BSD 2-clause (and GPL-2.0+). OpenSBI isn't being

Until recently, target install used to recurse into target directories
in its recipe: it ran make install in a for-loop. Since target
install depends on target all, this trivially ensured we run the
sub-make install only after completing target all.
Commit 1338a4b "Makefile: Reuse all's recursion machinery for clean
and install" moved the target recursion to dependencies. That's good
(the commit message explains why), but I forgot to add dependencies to
ensure make runs the sub-make install only after completing target
all. Do that now.
Fixes: 1338a4b726

CONFIG_TPM is defined to a rather weird $(CONFIG_SOFTMMU) so that it
expands to the right thing in hw/Makefile.objs. This however is not
needed anymore and it has a corresponding hack in create_config
to turn it into "#define CONFIG_TPM 1". Clean up.

The device directories must be included only for softmmu builds.
Instead of repeating $(CONFIG_SOFTMMU), use an "if".

Copy and pasting from Thunderbird's "view source" window results in double
encoding of multibyte UTF-8 sequences. The appearance of those sequences is
very peculiar, so detect it and give an error despite the (low) possibility
of false positives.
As the major offender, I am also adding the same check to my applypatch-msg
and commit-msg hooks, but this will also cause patchew to croak loudly when
this mistake happens.

When the backing_file is specified as a JSON object, the
qemu_gluster_reopen_prepare() fails with this message:
invalid URI json:{"server.0.host": ...}
In this case, we should call qemu_gluster_init() using the QDict
'state->options' that contains the JSON parameters already parsed.

That makes it OK to use a commit filter node there. Test that.

Currently, 030 just compares the error class, which does not say
anything.
Before HEAD^ added throttling to test_overlapping_4, that test actually
usually failed because node2 was already gone, not because it was the
commit and stream job were not allowed to overlap.
Prevent such problems in the future by comparing the error description
instead.
