Pali Rohár [Sat, 25 Dec 2021 14:52:20 +0000 (15:52 +0100)]
libpci: i386-io-windows.h: Enable I/O access via native NT ProcessUserModeIOPL syscall

libpci uses WinIo library from http://www.internals.com/ which is archived
at https://web.archive.org/web/20151005172744/http://www.internals.com/

This external WinIo library has two big issues:
1. Library license is incompatible with pciutils license.
2. It silently and automatically installs 3rd-party NT kernel module
   WinIo.sys which is bundled in WinIO.dll binary.

That NT kernel module creates a device file "\\.\WinIo" which can be opened
by any running process. Via this device file can any process (including
unprivileged or those running under Guest account) ask that kernel module
to configure x86 TSS I/O port permissions for access to any I/O port. That
NT kernel module does not implement any permission checks and automatically
accept all requests.

Change in this commit replaces insecure WinIO.dll library and WinIo.sys
kernel module by proper NT system solution: Usage of ProcessUserModeIOPL
syscall (equivalent of iopl(3) on Linux) which is supported directly by NT
kernel. It does not require any external 3rd-party library or NT kernel
module.

This syscall can be invoked by NtSetInformationProcess() function from
ntdll.dll library (which is part of NT system) and for privileged processes
kernel changes x86 IOPL to 3.

Privileged process is that which has SeTcbPrivilege (Act as part of the
operating system privilege) or is running under account from local
Administrators group with SeImpersonatePrivilege (Impersonate a client
after authentication privilege). SeImpersonatePrivilege is enabled by
default for accounts from local Administrators group.

Usage of privileges is not easy operation and needs to call lot of
functions to gain required permissions, achieve thread-safety and follow
suggested guidelines. Hence code is quite long.

Privileges (including SeTcbPrivilege) can be enabled / disabled in User
Accounts settings by local Administrators and change takes effect after
next login, not immediately.

Pali Rohár [Sat, 25 Dec 2021 12:45:28 +0000 (13:45 +0100)]
libpci: i386-io-windows.h: Fix definitions of I/O port functions for UCRT, CRTDLL and for 64-bit mode

Functions _outp(), _outpw(), _outpd(), _inp(), _inpw() and _inpd() are
available only in 32-bit version of the old MSVCRT library. They are not
available in 64-bit version of old MSVCRT library and neither the oldest
CRTDLL library or in new UCRT library.

Function prototypes for 32-bit mode should be available in <conio.h> header
file. But they are missing in some MinGW toolchains.

For 64-bit mode I/O port functions are defined only as inline functions or
intrinsics macros in <intrin.h> header file but under different names:
__outbyte(), __outword(), __outdword(), __inbyte(), __inword(), __indword()
This header file is available also in UCRT-compatible compilers.

When compiling with the oldest CRTDLL library and not using <intrin.h>
header file, it is required to provide own implementation of these
functions. Do it via inline assembly.

With this change it is possible to compile i386-io-windows.h with all
combination of toolchains, compilers, crt library and arch mode.

The most important is the fix to allow compilation with modern UCRT
library.

call-back in various back-ends. Most importantly, semantics of pci_dev->
known_fields was not formally defined and it was implemented inconsistently.

We now define known_fields as the set of fields which were already
obtained during the lifetime of the pci_dev. We never consider known
fields which are not supported by the back-end. All fields which are
unsupported by either the back-end, the OS, or the particular device,
are guaranteed to have sensible default values (0 or NULL). Also, bit
masks are always unsigned except for the signature of pci_fill_info()
which should be preferably kept stable.

All back-ends and the pci_generic_fill_info() function have been changed
to follow this semantics.

In the sysfs back-end, we read as few attributes as possible during
device initialization, so applications which use pci_get_dev() are not
slowed down unnecessarily.

pciutils: Decode Compute eXpress Link DVSEC

Compute eXpress Link[1] is a new CPU interconnect created with
workload accelerators in mind. The interconnect relies on PCIe
electrical and physical interconnect for communication via a Flex Bus
port which allows designs to choose between providing PCIe or CXL.

This patch introduces basic support for lspci decode of CXL and
builds upon the existing Designated Vendor-Specific support in
lspci through identification of a supporting CXL device using DVSEC
Vendor ID and DVSEC ID.
