SceKernelModulemgr

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

Module

This module exists only in non-secure world. The SELF can be found in os0:kd/modulemgr.skprx.

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

SELF Decryption

The following code can decrypt a SELF located at path. Set user to 1 if decrypting a user module else 0 for kernel. Set pathid 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 pathid to the right value for where the real path was. usecdram is for modules that are too large and won't fit in contiguous regular memory.

Module decryption and signature checks ("HENkaku patches" on 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 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.

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 os0: from ux0:. This is because it checks the PathId.

On 3.60, statically compiled self give an error.
