This ioctl accepts an arch-specific struct as an argument, so better split it
into several arch-specific ioctls.
To avoid compilation errors on exotic arches like MIPS, this patch also adds
sys/linux/dev_kvm_extra.txt that takes care of them.
While at it, also define KVM_GUESTDBG_USE_HW.

Add SYZOS calls that correspond to the IN and OUT x86 instructions
that perform port I/O.
These instructions have different variants, for now we just implement
the one that takes the port number from DX instead of encoding it in
the opcode.
|
| |
|
|
|
| |
Add a SYZOS call to write to one of the debug registers
(DR0-DR7).
|
| |
|
|
| |
Implement a pseudo-syscall to check the value of kvm_run.exit_reason
|
| |
|
|
|
|
| |
Not passing flattened arguments to syz_kvm_add_vcpu() serves two purposes:
- makes it easier to reason about the SYZOS program contents;
- prevents nonsensial mutations of them.
|

|
|
|
| |
Add a SYZOS call to write to one of the system registers
(CR0, CR2, CR3, CR4, CR8).
|
| |
|
|
| |
Let SYZOS execute RDMSR and WRMSR on x86.
|
| |
|
|
|
|
| |
Like we already do on ARM, use prime numbers multiplied by 10 for
SYZOS API IDs to prevent the compiler from emitting a jump table in
guest_main().

This is a system ioctl
|
| |
|
|
|
|
|
| |
Use output parameter instead of an input one.
Use a KVM constant for array size.

KVM_GET_MSRS can be both a system and a vcpu ioctl
|
| |
|
|
| |
Both KVM_SET_TSC_KHZ and KVM_GET_TSC_KHZ are vcpu and vm ioctls.

For certain ioctls https://www.kernel.org/doc/Documentation/virt/kvm/api.txt
lists their parameters as "in/out".
Change their descriptions to reflect that.
Also define KVM_GET_MSR_FEATURE_INDEX_LIST and KVM_GET_SUPPORTED_HV_CPUID

This patch adds the necessary descriptions for KVM_MEMORY_ENCRYPT_OP
that currently is not supported.

|

Somehow syz-extract is unable to infer KVM_MAX_IRQ_ROUTES on x86,
hardcode it.
|

|

This commit adds support for CPUID instructions on AMD64. It also adds a
relevant test.

This commit adds the actual SyzOS fuzzer for x86-64 and a small test. It
also updates some necessary parts of the ARM version and adds some glue
for i386.
|

|
|
|
|
| |
This commit moves the various x86/amd64 ioctl descriptions and their
relevant structs/flags to the architecture-specific file and updates
the corresponding const files.
|
|
|
This commit prepares adding the X86-64 SYZOS by declaring the relevant
functions, updating their ARM64 versions and adding placeholders.
