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.

Known NIDs

Version Name World Privilege NID
1.69 SceKernelModulemgr Non-secure Kernel 0xAFDA75C2
3.57 SceKernelModulemgr Non-secure Kernel 0x8FDDA3C0
3.60 SceKernelModulemgr Non-secure Kernel 0x726C6635
3.65 SceKernelModulemgr Non-secure Kernel 0x781C6F50

Libraries

This module exports kernel and user libraries.

Loading Sequence

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

typedef struct
{
    const char *filename; // 0x64
    Elf32_Ehdr ehdr;        // 0x74
    Elf32_Phdr phdr;        // 0xA8

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)

SELF_Loading.

The code below will patch signature checks and bypass module decryption and allow homebrew 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 hook_resume_sbl_* defines (set them to addresses of functions) and INSTALL_HOOK second arguments (set to addresses of imports in SceKernelModulemgr). 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, 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 libraries 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.

Was wrongly named sceKernelLoadStartDefaultSharedModulesForPidForKernel.

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