The kernel module now links and compiles, there are still a lot of empty TODOs left, there are empty stubs for hypertrace, assembly files and kdserial etc. these can be introduced one by one. My first step will be loading the kernel module from the userspace cli. Big step forward! :)

* @file Driver-linux.c
|
|
* @brief Linux stand-in for the Windows-only Driver.c (WDM driver bootstrap)
|
|
*
|
|
* @details The upstream Driver.c is pure WDM: DriverEntry() builds a DRIVER_OBJECT/
|
|
* DEVICE_OBJECT, fills the IRP_MJ_* dispatch table (DrvCreate/Read/Write/Close/
|
|
* Unsupported), creates the \\Device and \\DosDevices symbolic link, and gates
|
|
* access with SeSinglePrivilegeCheck(SE_DEBUG_PRIVILEGE). None of that model
|
|
* exists on Linux (DRIVER_OBJECT is only an opaque forward-decl in WdkTypes.h),
|
|
* so — following the established `*-linux.c` whole-file swap convention (see
|
|
* ZydisKernel-linux.c) — the Linux module compiles this stand-in instead of
|
|
* Driver.c. The Windows build keeps compiling the original Driver.c unchanged
|
|
* (still in hyperkd.vcxproj); this file is Kbuild-only.
|
|
*
|
|
* It is intentionally an EMPTY skeleton for now: the char-device layer is the one
|
|
* genuine design piece left in hyperkd and is deferred to its own pass.
|
|
*
|
|
* TODO(Linux): replace the WDM bootstrap with a misc/char device —
|
|
* - module_init()/module_exit() in place of DriverEntry()/DrvUnload()
|
|
* - alloc_chrdev_region() + cdev_add() (or misc_register()) for the /dev node
|
|
* - a struct file_operations whose .unlocked_ioctl dispatches into the existing
|
|
* IOCTL handler (Ioctl.c, DrvDispatchIoControl equivalent), .open/.release
|
|
* standing in for DrvCreate/DrvClose
|
|
* - capable(CAP_SYS_PTRACE)/CAP_SYS_ADMIN in place of the SE_DEBUG_PRIVILEGE check
