SceKernelModulemgr is in charge of loading both user modules and kernel modules. SceKernelModulemgr calls [[SceSblAuthMgr]] functions for the SELF decryption process. SceKernelModulemgr loads the ELF programs into memory along with linking with NIDs and relocation of ELF in position independent executables.

=== How to get module info ===
−
The following code can decrypt a SELF located at <code>path</code>. Set <code>user</code> to 1 if decrypting a user module else 0 for kernel. Set <code>pathid</code> to 0 if you're decrypting the SELF at the right location (for example decrypting <code>sysmem.skprx</code> located in <code>os0:</code>). If you have copied the SELF elsewhere, you need to set the <code>[[SceSblACMgr#PathId|pathid]]</code> to the right value for where the real path was. <code>usecdram</code> is for modules that are too large and won't fit in contiguous regular memory.

The code below will patch signature checks and bypass module decryption and allow homebrews to run. The idea is to hook SceSblAuthMgr* calls that are imported to SceKernelModulemgr. The offsets are from 1.60, you will probably need to modify functions defines (set to addresses of functions) and INSTALL_HOOK second arguments (set to addresses of imports in SceKernelModulemgr).

−
For old FWs like 1.60, as there is no kASLR, you can set hardcoded addresses, else take HENkaku code. As a bonus there's also patch_npdrm functions that patches [[SceNpDrm]] to bypass some DRM checks and allow unsigned packages to be installed, which you also need to modify addresses. See [[SceNpDrm#Package_integrity_checks]].

The code below will patch signature checks and bypass module decryption and allow homebrews to run. The idea is to hook SceSblAuthMgr* calls that are imported to SceKernelModulemgr. The offsets are from FW 1.60, you will probably need to modify functions defines (set to addresses of functions) and INSTALL_HOOK second arguments (set to addresses of imports in SceKernelModulemgr).
−
{| class="wikitable"
+
For old FWs like 1.60, as there is no kASLR, you can set hardcoded addresses, else take HENkaku code. As a bonus there is also patch_npdrm functions that patches [[SceNpDrm]] to bypass some DRM checks and allow unsigned packages to be installed, which you also need to modify addresses. See [[SceNpDrm#Package_integrity_checks]].

This is an easy way of decrypting SELFs but you are limited to the kinds of SELFs you can load in the current context (for example, you can't load user modules from kernel context). It is also susceptible to limitations of where the SELF can be loaded from. For example, you are not allowed to load SELFs found in <code>os0:</code> from <code>ux0:</code>. This is because it checks the [[SceSblACMgr#PathId|PathId]].

This loads the default shared modules for a process (only the ones that are actually imported). This includes, for example, <code>SceLibKernel</code>. Modules are loaded with flags <code>0x10000000</code> meaning that text pages can be shared. If dipsw 210 is set, then flag <code>0x1000</code> is set, meaning that if the existing page is found, do not share it but instead make a copy.

This function can only be called in System program.
 +
 
 +
This function was maybe removed because it represented a security threat: an exploit giving usermode code execution in a System program (for example PSPemu sandbox escape) could change the System Software version in SceKernelModulemgr data segment. The impact depends on which modules relied on that version buffer.

Introduced in System Software version 3.50 to prevent loading Sysmodules from the webbrowser. It is a security feature that makes kernel exploitation harder because it reduces the number of accessible syscalls from a WebKit usermode exploit.
 +
 
 +
See also Vitasploit 2.00-3.36 post-WebKit-exploit API and h-encore 3.65-3.68 writeup by TheFloW.
 +
 
 +
In [https://github.com/TheOfficialFloW/Trinity/blob/master/eboot/arm.c#L203 Trinity source code], a module is loaded with flags = 0x10 to bypass sceKernelInhibitLoadingModule(0x20) restriction.
 +
 
 +
Used in [[ScePspemu]] (probably level 0x20), [[SceWebKitProcess]], [[SceWebKitProcessMini]].
 +
 
 +
Returns 0 on success. Returns 0x80020005 if level is invalid.
 +
 
 +
Level must be strictly increasing: loading a module becomes more and more inhibited.

SceKernelModulemgr is in charge of loading both user modules and kernel modules. SceKernelModulemgr calls SceSblAuthMgr functions for the SELF decryption process. SceKernelModulemgr loads the ELF programs into memory along with linking with NIDs and relocation of ELF in position independent executables.

Module

Version World Privilege
0.940-3.60 Non-secure Kernel

The SELF can be found in os0:kd/modulemgr.skprx.

Functions of this module are also embedded in NSKBL.

Libraries

This module exports kernel and user libraries.

Notes

Error codes

0x8002D018

The shared module is not importable be non-shared module and non-syscall.

0x8002D01E

Attempted to load a module with a start entry as bootfs.

Attempted to load a module that has syscall exports to usermode.

module_start no resident/failed

If module_start returns SCE_KERNEL_START_NO_RESIDENT, the module will start successfully, but it will be unloaded after the module_start call.

However, if the module_start of the module where the syscall export exists is called after boot and returns SCE_KERNEL_START_NO_RESIDENT/SCE_KERNEL_START_FAILED, then a kernel panic is triggered.

How to get module info

modid and SceUIDModuleClass are required to get module information.

Simply call sceGUIDReferObjectForDriver(sceKernelGetObjectForUidForDriver) with these parameters.

Module decrypt threads

SceKernelModulemgr_func_8100910D

This thread keeps waiting at sceKernelWaitEventFlagForDriver until a module decrypt request comes.

bits of sceKernelWaitEventFlagForDriver is 3.

When loading a module the sequence creates a SceModule structure to represent it.

    const char *filename;   // 0x64

SELF Decryption

The following code can decrypt a SELF located at path.

Set self_type to 1 if decrypting a usermode module else 0 for kernel (2 for SM but maybe not allowed).

Set media_type to 0 if you're decrypting the SELF at the right location (for example decrypting sysmem.skprx located in os0:). If you have copied the SELF elsewhere, you need to set the media_type to the right value for where the real path was.

use_cdram is for modules that are too large and won't fit in contiguous regular memory.

Module decryption and signature checks ("HENkaku patches" on FW 1.60)

See also SELF_Loading to see how these SceSblAuthMgr functions are used to decrypt SELFs.

The code below will patch signature checks and bypass module decryption and allow homebrews to run. The idea is to hook SceSblAuthMgr* calls that are imported to SceKernelModulemgr. The offsets are from FW 1.60, you will probably need to modify functions defines (set to addresses of functions) and INSTALL_HOOK second arguments (set to addresses of imports in SceKernelModulemgr). For old FWs like 1.60, as there is no kASLR, you can set hardcoded addresses, else take HENkaku code. As a bonus there is also patch_npdrm functions that patches SceNpDrm to bypass some DRM checks and allow unsigned packages to be installed, which you also need to modify addresses. See SceNpDrm#Package_integrity_checks.

This is an easy way of decrypting SELF files but you are limited to the kinds of SELF files that you can load in the current context (for example, you cannot load user modules from kernel context). It is also susceptible to limitations of where the SELF can be loaded from. For example, you are not allowed to load SELFs found in os0: from ux0: because Secure Kernel checks the Media Type.

On FW 3.60, statically compiled SELF files give an error.

sceKernelInhibitLoadingModule

Version NID
0.931.010-3.36 not present
3.500.011-3.740.011 0x6CED1F63

Introduced in System Software version 3.50 to prevent loading Sysmodules from the webbrowser. It is a security feature that makes kernel exploitation harder because it reduces the number of accessible syscalls from a WebKit usermode exploit.

See also Vitasploit 2.00-3.36 post-WebKit-exploit API and h-encore 3.65-3.68 writeup by TheFloW.

In Trinity source code, a module is loaded with flags = 0x10 to bypass sceKernelInhibitLoadingModule(0x20) restriction.

Used in ScePspemu (probably level 0x20), SceWebKitProcess, SceWebKitProcessMini.

Returns 0 on success. Returns 0x80020005 if level is invalid.

Level must be strictly increasing: loading a module becomes more and more inhibited. 

#define SCE_MODULE_LOADING_INHIBIT_TO_FLAGS_0x8000_AND_SHARED 0x10
#define SCE_MODULE_LOADING_INHIBIT_TO_FLAGS_0x10 0x20

// level: Only values 0x10, 0x20, 0x30 are supported.
