The NT path resolver allows mapping between an ARC path as specified in freeldr.ini / boot.ini , to its corresponding NT path, if possible. Currently, only the mapping direction "ARC to NT" is implemented. It will be used wherever such mappings are needed, for example when identifying the ReactOS / Windows installations from the available freeldr.ini / boot.ini entries (for upgrading / repair purposes). The resolver supports the usual ARC paths: multi()disk()[r|f]disk()[partition()] ; eisa()disk()[r|f]disk()[partition()] ; multi()disk()cdrom() ; scsi()disk()[r|f]disk()[partition()] ; scsi()cdrom()fdisk() ; ramdisk(x) ; net(x) (actually reported as "unsupported" since it would map to some path on some network), and the newly-introduced Win2k signature()disk()rdisk()[partition()]. The code is in work-in-progress status. Some validation tests, that were used during the implementation of the resolver, have been added. svn path=/branches/setup_improvements/; revision=74621 svn path=/branches/setup_improvements/; revision=74631 --- base/setup/lib/CMakeLists.txt | 1 + base/setup/lib/arcname.c | 860 +++++++++++++++++++++++++++++++++++++++++ base/setup/lib/arcname.h | 21 + base/setup/lib/arcname_tests.c | 134 +++++++ base/setup/lib/setuplib.h | 2 + 5 files changed, 1018 insertions(+) diff --git a/base/setup/lib/CMakeLists.txt b/base/setup/lib/CMakeLists.txt index 258a14b03c..a37be9d1fb 100644 --- a/base/setup/lib/CMakeLists.txt +++ b/base/setup/lib/CMakeLists.txt @@ -1,5 +1,6 @@ list(APPEND SOURCE + arcname.c fsutil.c genlist.c ntverrsrc.c diff --git a/base/setup/lib/arcname.c b/base/setup/lib/arcname.c new file mode 100644 index 0000000000..d2ea9d927a --- /dev/null +++ b/base/setup/lib/arcname.c @@ -0,0 +1,860 @@ +/* + * PROJECT: ReactOS Setup Library + * LICENSE: GPL-2.0+ (https://spdx.org/licenses/GPL-2.0+) + * PURPOSE: ARC path to-and-from NT path resolver. + * COPYRIGHT: Copyright 2017-2018 Hermes Belusca-Maito + */ +/* + * References: + * + * - ARC Specification v1.2: http://netbsd.org./docs/Hardware/Machines/ARC/riscspec.pdf + * - "Setup and Startup", MSDN article: https://technet.microsoft.com/en-us/library/cc977184.aspx + * - Answer for "How do I determine the ARC path for a particular drive letter in Windows?": https://serverfault.com/a/5929 + * - ARC - LinuxMIPS: https://www.linux-mips.org/wiki/ARC + * - ARCLoad - LinuxMIPS: https://www.linux-mips.org/wiki/ARCLoad + * - Inside Windows 2000 Server: https://books.google.fr/books?id=kYT7gKnwUQ8C&pg=PA71&lpg=PA71&dq=nt+arc+pa… + * - Inside Windows Server 2003: https://books.google.fr/books?id=zayrcM9ZYdAC&pg=PA61&lpg=PA61&dq=arc+path+… + * + * Stuff to read: http://www.adminxp.com/windows2000/index.php?aid=46 and http://www.trcb.com/Computers-and-Technology/Windows-XP/Windows-XP-ARC-Nami… + * concerning which values of disk() or rdisk() are valid when either scsi() or multi() adapters are specified. + */ + +/* INCLUDES *****************************************************************/ + +#include "precomp.h" + +#include "partlist.h" +#include "arcname.h" + +#define NDEBUG +#include <debug.h> + + +/* Supported adapter types */ +typedef enum _ADAPTER_TYPE +{ + EisaAdapter, + ScsiAdapter, + MultiAdapter, + NetAdapter, + RamdiskAdapter, + AdapterTypeMax +} ADAPTER_TYPE, *PADAPTER_TYPE;

The aim is to use this detector to be able to detect and select an existing installation of ReactOS for upgrading. The user then could either select one, or skip this step and perform a regular ReactOS installation. What remains to be done, is to parse the NTOS loader configuration files (freeldr.ini in ReactOS' case, or boot.ini in Win2k3's case, etc...) to retrieve the actual installation paths. So far these are currently hardcoded for testing purposes only. The detector attempts to distinguish between ReactOS and Windows installations by checking at the company name vendor of the ntoskrnl.exe & ntdll.dll files, so that only ReactOS installations are allowed to be upgraded. svn path=/branches/setup_improvements/; revision=74527 svn path=/branches/setup_improvements/; revision=74550 --- base/setup/usetup/CMakeLists.txt | 1 + base/setup/usetup/osdetect.c | 834 +++++++++++++++++++++++++++++++++++++++ base/setup/usetup/osdetect.h | 22 ++ base/setup/usetup/usetup.h | 1 + 4 files changed, 858 insertions(+) diff --git a/base/setup/usetup/CMakeLists.txt b/base/setup/usetup/CMakeLists.txt index 69d1e6b4e3..714182e7e7 100644 --- a/base/setup/usetup/CMakeLists.txt +++ b/base/setup/usetup/CMakeLists.txt @@ -27,6 +27,7 @@ list(APPEND SOURCE inicache.c keytrans.c mui.c + osdetect.c partlist.c progress.c registry.c diff --git a/base/setup/usetup/osdetect.c b/base/setup/usetup/osdetect.c new file mode 100644 index 0000000000..60fd7ef644 --- /dev/null +++ b/base/setup/usetup/osdetect.c @@ -0,0 +1,834 @@ +/* + * PROJECT: ReactOS Setup Library + * LICENSE: GPL-2.0+ (https://spdx.org/licenses/GPL-2.0+) + * PURPOSE: NT 5.x family (MS Windows <= 2003, and ReactOS) + * operating systems detection code. + * COPYRIGHT: Copyright 2017-2018 Hermes Belusca-Maito + */ + +#include "usetup.h" + +#include <ndk/ldrtypes.h> +#include <ndk/ldrfuncs.h> + +// HACK! +#include <strsafe.h> + +#define NDEBUG +#include <debug.h> + + +/* GLOBALS ******************************************************************/ + +extern PPARTLIST PartitionList; + +/* Language-independent Vendor strings */ +static const PCWSTR KnownVendors[] = { L"ReactOS", L"Microsoft" }; + + +/* VERSION RESOURCE API ******************************************************/ + +/* + * NT-oriented version resource management, adapted from dll/win32/version. + * We only deal with 32-bit PE executables. + */ + +NTSTATUS +NtGetVersionResource( + IN PVOID BaseAddress, + OUT PVOID* Resource, + OUT PULONG ResourceSize OPTIONAL) +{ +// #define RT_VERSION MAKEINTRESOURCE(16) // See winuser.h +#define VS_VERSION_INFO 1 // See psdk/verrsrc.h +#define VS_FILE_INFO RT_VERSION + + NTSTATUS Status; + LDR_RESOURCE_INFO ResourceInfo; + PIMAGE_RESOURCE_DATA_ENTRY ResourceDataEntry; + PVOID Data = NULL; + ULONG Size = 0; + + /* Try to find the resource */ + ResourceInfo.Type = 16; // RT_VERSION; + ResourceInfo.Name = VS_VERSION_INFO; // MAKEINTRESOURCEW(VS_VERSION_INFO); + ResourceInfo.Language = 0; // Don't care about the language + + Status = LdrFindResource_U(BaseAddress, + &ResourceInfo, + RESOURCE_DATA_LEVEL, + &ResourceDataEntry); + if (!NT_SUCCESS(Status)) + { + DPRINT1("NtGetVersionResource: Version resource not found, Status 0x%08lx\n", Status); + return Status; + } + + /* Access the resource */ + Status = LdrAccessResource(BaseAddress, + ResourceDataEntry, + &Data, + &Size); + if (!NT_SUCCESS(Status)) + { + DPRINT1("NtGetVersionResource: Cannot access Version resource, Status 0x%08lx\n", Status); + return Status; + } + + *Resource = Data; + if (ResourceSize) *ResourceSize = Size; + + return STATUS_SUCCESS; +} + +/* NOTE: the xxx_STRUCT16 version differs by storing strings in ANSI, not in UNICODE */ +typedef struct _VS_VERSION_INFO_STRUCT32 +{ + WORD wLength; + WORD wValueLength; + WORD wType; /* 1:Text, 0:Binary */ + WCHAR szKey[1]; +#if 0 /* variable length structure */ + /* DWORD aligned */ + BYTE Value[]; + /* DWORD aligned */ + VS_VERSION_INFO_STRUCT32 Children[]; +#endif +} VS_VERSION_INFO_STRUCT32, *PVS_VERSION_INFO_STRUCT32; +typedef const VS_VERSION_INFO_STRUCT32 *PCVS_VERSION_INFO_STRUCT32; + +#define DWORD_ALIGN( base, ptr ) \ + ( (ULONG_PTR)(base) + ((((ULONG_PTR)(ptr) - (ULONG_PTR)(base)) + 3) & ~3) ) + +#define VersionInfo32_Value( ver ) \ + DWORD_ALIGN( (ver), (ver)->szKey + wcslen((ver)->szKey) + 1 ) + +#define VersionInfo32_Children( ver ) \ + (PCVS_VERSION_INFO_STRUCT32)( VersionInfo32_Value( ver ) + \ + ( ( (ver)->wValueLength * \ + ((ver)->wType?
