They date back from commit a880f2ee (r9611), and were the root cause for the bug that was tentatively fixed by commit 81a9ce44e (PR #755). On Windows, boot file system drivers have either the SERVICE_DEMAND_START or the SERVICE_DISABLED start type, and only the filesystem to access the boot media is manually loaded by the OS loader (other FSes that are needed later are loaded by the FSRecognizer). Also there is no need to disable NTFS anymore. --- boot/bootdata/livecd.inf | 6 ------ 1 file changed, 6 deletions(-) diff --git a/boot/bootdata/livecd.inf b/boot/bootdata/livecd.inf index eae91147fa4..ad88590eb13 100644 --- a/boot/bootdata/livecd.inf +++ b/boot/bootdata/livecd.inf @@ -10,15 +10,9 @@ HKLM,"SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders" ; Default locale for the keyboard layout HKU,".DEFAULT\Keyboard Layout\Preload","1",0x00000000,"00000409" -; Cdfs (ISO96660) filesystem driver -HKLM,"SYSTEM\CurrentControlSet\Services\Cdfs","Start",0x00010001,0x00000000 - ; Cdrom class driver HKLM,"SYSTEM\CurrentControlSet\Services\Cdrom","Start",0x00010001,0x00000000 -; FIXME: Disable NTFS driver -HKLM,"SYSTEM\CurrentControlSet\Services\Ntfs","Start",0x00010001,0x00000004 - ; Reset BootExecute to an empty value: AutoChk should not start in MiniNT mode HKLM,"SYSTEM\CurrentControlSet\Control\Session Manager","BootExecute",0x00010000,""

[reactos] 01/01: [NTOS:CM] Adapt cmboot.c for usage in NT/ReactOS bootloader.

https://git.reactos.org/?p=reactos.git;a=commitdiff;h=6ff02323684cac98a944b… commit 6ff02323684cac98a944b54916ad3fb652a1304d Author: Hermès Bélusca-Maïto <hermes.belusca-maito(a)reactos.org> AuthorDate: Mon Mar 21 23:16:19 2022 +0100 Commit: Hermès Bélusca-Maïto <hermes.belusca-maito(a)reactos.org> CommitDate: Sat Apr 16 18:37:45 2022 +0200 [NTOS:CM] Adapt cmboot.c for usage in NT/ReactOS bootloader. - Add a new cmboot.h header to isolate the boot-support definitions shared with the NT/ReactOS bootloader. - Move CmpFreeDriverList() to cmboot.c so that we can use it for cleanup paths in the NT/ReactOS bootloader. - CmpFindControlSet(): Directly build the control set name in UNICODE, instead of doing an ANSI->UNICODE conversion. - Directly assign the CurrentControlSet\Services constant string, instead of going the route of init-empty-string + append-string. This is possible since that string is not modified later. - Remove ASSERT(FALSE), replacing them with correct failure handling. - Add cleanup paths in CmpAddDriverToList(). - Simplify and fix CmpFreeDriverList(): it's the full DriverNode that needs to be freed; not the LIST_ENTRY pointer. - Add other validity checks: * Registry value types and data sizes; * For multi-strings, verify that they are NULL-terminated. * For (multi-)strings, check whether they are NULL-terminated before optionally removing their trailing NULL character from the count. Check also whether they are of zero-length and take appropriate action where necessary. - Add CmpIsDriverInList() for future usage in CMBOOT compiled in bootloader mode. - Add SAL annotations and Doxygen documentation. - Add debug traces. - Formatting / code style fixes. ** TODO: Fix SafeBoot support ** --- ntoskrnl/config/cmboot.c | 953 +++++++++++++++++++++++++++---------- ntoskrnl/config/cmsysini.c | 49 -- ntoskrnl/include/internal/cm.h | 52 +- ntoskrnl/include/internal/cmboot.h | 80 ++++ ntoskrnl/include/internal/io.h | 24 +- 5 files changed, 786 insertions(+), 372 deletions(-) diff --git a/ntoskrnl/config/cmboot.c b/ntoskrnl/config/cmboot.c index 98dd2a053ef..fdd1a6ed6c4 100644 --- a/ntoskrnl/config/cmboot.c +++ b/ntoskrnl/config/cmboot.c @@ -1,166 +1,260 @@ /* - * PROJECT: ReactOS Kernel - * LICENSE: BSD - See COPYING.ARM in the top level directory - * FILE: ntoskrnl/config/cmboot.c - * PURPOSE: Configuration Manager - Boot Initialization - * PROGRAMMERS: ReactOS Portable Systems Group - * Alex Ionescu (alex.ionescu(a)reactos.org) + * PROJECT: ReactOS Kernel + * LICENSE: BSD - See COPYING.ARM in the top level directory + * PURPOSE: Configuration Manager - Boot Initialization + * COPYRIGHT: Copyright 2007 Alex Ionescu (alex.ionescu(a)reactos.org) + * Copyright 2010 ReactOS Portable Systems Group + * Copyright 2022 Hermès Bélusca-Maïto + * + * NOTE: This module is shared by both the kernel and the bootloader. */ /* INCLUDES *******************************************************************/ -#include "ntoskrnl.h" +#include <ntoskrnl.h> + #define NDEBUG -#include "debug.h" +#include <debug.h> -/* GLOBALS ********************************************************************/ +#ifdef _BLDR_ + +#undef CODE_SEG +#define CODE_SEG(...) + +#include <ntstrsafe.h> +#include <cmlib.h> +#include "internal/cmboot.h" + +// HACK: This is part of non-NT-compatible SafeBoot support in kernel. +ULONG InitSafeBootMode = 0; + +DBG_DEFAULT_CHANNEL(REGISTRY); +#define CMTRACE(x, fmt, ...)
