2022-12-02ACPICA: Fix use-after-free in acpi_ut_copy_ipackage_to_ipackage()Li Zetao1-7/+0
There is an use-after-free reported by KASAN: BUG: KASAN: use-after-free in acpi_ut_remove_reference+0x3b/0x82 Read of size 1 at addr ffff888112afc460 by task modprobe/2111 CPU: 0 PID: 2111 Comm: modprobe Not tainted 6.1.0-rc7-dirty Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), Call Trace: <TASK> kasan_report+0xae/0xe0 acpi_ut_remove_reference+0x3b/0x82 acpi_ut_copy_iobject_to_iobject+0x3be/0x3d5 acpi_ds_store_object_to_local+0x15d/0x3a0 acpi_ex_store+0x78d/0x7fd acpi_ex_opcode_1A_1T_1R+0xbe4/0xf9b acpi_ps_parse_aml+0x217/0x8d5 ... </TASK> The root cause of the problem is that the acpi_operand_object is freed when acpi_ut_walk_package_tree() fails in acpi_ut_copy_ipackage_to_ipackage(), lead to repeated release in acpi_ut_copy_iobject_to_iobject(). The problem was introduced by "8aa5e56eeb61" commit, this commit is to fix memory leak in acpi_ut_copy_iobject_to_iobject(), repeatedly adding remove operation, lead to "acpi_operand_object" used after free. Fix it by removing acpi_ut_remove_reference() in acpi_ut_copy_ipackage_to_ipackage(). acpi_ut_copy_ipackage_to_ipackage() is called to copy an internal package object into another internal package object, when it fails, the memory of acpi_operand_object should be freed by the caller.

2022-11-08ACPICA: Fix error code path in acpi_ds_call_control_method()Rafael J. Wysocki1-2/+8
A use-after-free in acpi_ps_parse_aml() after a failing invocaion of acpi_ds_call_control_method() is reported by KASAN [1] and code inspection reveals that next_walk_state pushed to the thread by acpi_ds_create_walk_state() is freed on errors, but it is not popped from the thread beforehand. Thus acpi_ds_get_current_walk_state() called by acpi_ps_parse_aml() subsequently returns it as the new walk state which is incorrect. To address this, make acpi_ds_call_control_method() call acpi_ds_pop_walk_state() to pop next_walk_state from the thread before returning an error.

ACPICA commit 2d8dc0383d3c908389053afbdc329bbd52f009ce The CXL 3.0 Specification [1] adds two new structures to the CXL Early Discovery Table (CEDT). The CEDT may include zero or more entries of these types: CXIMS: CXL XOR Interleave Math Structure Enables the host to find a targets position in an Interleave Target List when XOR Math is used. RDPAS: RCEC Downstream Post Association Structure Enables the host to locate the Downstream Port(s) that report errors to a given Root Complex Event Collector (RCEC).

2022-10-28ACPICA: Add support for FFH Opregion special context dataSudeep Holla5-2/+30
ACPICA commit fad527b6e76babc7527c41325bfbef6bd1a1132b FFH(Fixed Function Hardware) Opregion is approved to be added in ACPI 6.5 via code first approach [1]. It requires special context data similar to GPIO and Generic Serial Bus as it needs to know platform specific offset and length. Add support for the special context data needed by FFH Opregion. FFH op_region enables advanced use of FFH on some architectures. For example, it could be used to easily proxy AML code to architecture-specific behavior (to ensure it is OS initiated) Actual behavior of FFH is ofcourse architecture specific and depends on the FFH bindings. The offset and length could have arch specific meaning or usage.

ACPICA commit a36eda9631e84f271319c41288889dd5b1329369 The ACPICA code assumes that EBDA region must be at least 1ki_b in size. Because this is not guaranteed, it might happen that while scanning the memory for RSDP pointer, the kernel touches memory above 640ki_b. This is unwanted as the VGA memory range may not be decoded or even present when running under virtualization.

This reverts commit 72a95859728a7866522e6633818bebc1c2519b17. It broke reboots on big-endian MIPS and MIPS64 malta QEMU instances, which use the syscon driver. Little-endian is not effected, which means likely it's important to handle regmap_get_val_endian() in this function after all.

2022-10-22KVM: x86: Add compat handler for KVM_X86_SET_MSR_FILTERAlexander Graf1-0/+56
The KVM_X86_SET_MSR_FILTER ioctls contains a pointer in the passed in struct which means it has a different struct size depending on whether it gets called from 32bit or 64bit code. This patch introduces compat code that converts from the 32bit struct to its 64bit counterpart which then gets used going forward internally. With this applied, 32bit QEMU can successfully set MSR bitmaps when running on 64bit kernels.

2022-10-22KVM: x86: Copy filter arg outside kvm_vm_ioctl_set_msr_filter()Alexander Graf1-14/+17
In the next patch we want to introduce a second caller to set_msr_filter() which constructs its own filter list on the stack. Refactor the original function so it takes it as argument instead of reading it through copy_from_user().

2022-10-21x86/fpu: Fix copy_xstate_to_uabi() to copy init states correctlyChang S. Bae1-0/+9
When an extended state component is not present in fpstate, but in init state, the function copies from init_fpstate via copy_feature(). But, dynamic states are not present in init_fpstate because of all-zeros init states. Then retrieving them from init_fpstate will explode like this: BUG: kernel NULL pointer dereference, address: 0000000000000000 ... RIP: 0010:memcpy_erms+0x6/0x10 ? __copy_xstate_to_uabi_buf+0x381/0x870 fpu_copy_guest_fpstate_to_uabi+0x28/0x80 kvm_arch_vcpu_ioctl+0x14c/0x1460 [kvm] ? __this_cpu_preempt_check+0x13/0x20 ? vmx_vcpu_put+0x2e/0x260 [kvm_intel] kvm_vcpu_ioctl+0xea/0x6b0 [kvm] ? kvm_vcpu_ioctl+0xea/0x6b0 [kvm] ? __fget_light+0xd4/0x130 __x64_sys_ioctl+0xe3/0x910 ? debug_smp_processor_id+0x17/0x20 ? fpregs_assert_state_consistent+0x27/0x50 do_syscall_64+0x3f/0x90 entry_SYSCALL_64_after_hwframe+0x63/0xcd Adjust the 'mask' to zero out the userspace buffer for the features that are not available both from fpstate and from init_fpstate. The dynamic features depend on the compacted XSAVE format. Ensure it is enabled before reading XCOMP_BV in init_fpstate.
