Security fix for CVE-2017-13693, CVE-2017-13694, CVE-2017-13695.

This provides fixes for the user space ACPICA tools only. Any kernel updates are handled separately.

This update also includes the upgrade to the 20190209 version of the upstream source. 

---------------------------------------- 09 February 2018. Summary of changes for version 20180209 :

1) ACPICA kernel-resident subsystem :

Completed the final integration of the recent changes to Package Object handling and the module-level AML code support. This allows forward references from individual package elements when the package object is declared from within module-level code blocks. Provides compatibility with other ACPI implementations.

The new architecture for the AML module-level code has been completed and is now the default for the ACPICA code. This new architecture executes the module-level code in-line as the ACPI table is loaded/parsed instead of the previous architecture which deferred this code until after the table was fully loaded. This solves some ASL code ordering issues and provides compatibility with other ACPI implementations. At this time, there is an option to fallback to the earlier architecture, but this support is deprecated and is planned to be completely removed later this year.

Added a compile-time option to ignore AE_NOT_FOUND exceptions during resolution of named reference elements within Package objects.
Although this is potentially a serious problem, it can generate a lot of noise/errors on platforms whose firmware carries around a bunch of unused Package objects. To disable these errors, define ACPI_IGNORE_PACKAGE_RESOLUTION_ERRORS in the OS-specific header. All errors are always reported for ACPICA applications such as AcpiExec.

Fixed a regression related to the explicit type-conversion AML operators (ToXXXX). The regression was introduced early in 2017 but was not seen until recently because these operators are not fully supported by other ACPI implementations and are thus rarely used by firmware developers. The operators are defined by the ACPI specification to not implement the 'implicit result object conversion'. The regression incorrectly introduced this object conversion for the following explicit conversion operators :

  - ToInteger

  - ToString

  - ToBuffer

  - ToDecimalString

  - ToHexString

  - ToBCD

  - FromBCD

2) iASL Compiler/Disassembler and Tools :

iASL: Fixed a problem with the compiler constant folding feature as related to the ToXXXX explicit conversion operators. These operators do not support the 'implicit result object conversion' by definition.
Thus, ASL expressions that use these operators cannot be folded to a simple Store operator because Store implements the implicit conversion. This change uses the CopyObject operator for the ToXXXX operator folding instead. CopyObject is defined to not implement implicit result conversions and is thus appropriate for folding the ToXXXX operators.

iASL: Changed the severity of an error condition to a simple warning for the case where a symbol is declared both locally and as an external symbol. This accommodates existing ASL code.

AcpiExec: The -ep option to enable the new architecture for module-level code has been removed. It is replaced by the -dp option which instead has the opposite effect: it disables the new architecture (the default) and enables the legacy architecture. When the legacy code is removed in the future, the -dp option will be removed also.

  - The iscsi_if_rx function in     drivers/scsi/scsi_transport_iscsi.c in the Linux kernel     through 4.13.2 allows local users to cause a denial of     service (panic) by leveraging incorrect length     validation.(CVE-2017-14489)

  - The move_pages system call in mm/migrate.c in the Linux     kernel before 4.12.9 doesn't check the effective uid of     the target process, enabling a local attacker to learn     the memory layout of a setuid executable despite     ASLR.(CVE-2017-14140)

  - The offset2lib patch as used in the Linux Kernel     contains a vulnerability that allows a PIE binary to be     execve()'ed with 1GB of arguments or environmental     strings then the stack occupies the address 0x80000000     and the PIE binary is mapped above 0x40000000     nullifying the protection of the offset2lib patch. This     affects Linux Kernel version 4.11.5 and earlier. This     is a different issue than CVE-2017-1000371. This issue     appears to be limited to i386 based     systems.(CVE-2017-1000370)

  - Race condition in fs/timerfd.c in the Linux kernel     before 4.10.15 allows local users to gain privileges or     cause a denial of service (list corruption or     use-after-free) via simultaneous file-descriptor     operations that leverage improper might_cancel     queueing.(CVE-2017-10661)

  - The acpi_ds_create_operands() function in     drivers/acpi/acpica/dsutils.c in the Linux kernel     through 4.12.9 does not flush the operand cache and     causes a kernel stack dump, which allows local users to     obtain sensitive information from kernel memory and     bypass the KASLR protection mechanism (in the kernel     through 4.9) via a crafted ACPI table.(CVE-2017-13693)

  - The tcp_disconnect function in net/ipv4/tcp.c in the     Linux kernel before 4.12 allows local users to cause a     denial of service (__tcp_select_window divide-by-zero     error and system crash) by triggering a disconnect     within a certain tcp_recvmsg code path.(CVE-2017-14106)

  - The native Bluetooth stack in the Linux Kernel (BlueZ),     starting at the Linux kernel version 3.3-rc1 and up to     and including 4.13.1, are vulnerable to a stack     overflow vulnerability in the processing of L2CAP     configuration responses resulting in Remote code     execution in kernel space.(CVE-2017-1000251

  - )

  - The prepare_vmcs02 function in arch/x86/kvm/vmx.c in     the Linux kernel through 4.13.3 does not ensure that     the 'CR8-load exiting' and 'CR8-store exiting' L0     vmcs02 controls exist in cases where L1 omits the 'use     TPR shadow' vmcs12 control, which allows KVM L2 guest     OS users to obtain read and write access to the     hardware CR8 register.(CVE-2017-12154)
