TODO

Now

• Support load symbol-file like gdb.
• Some symbols will be optimized out.
• support Qemu
• support multi-thread and make each thread safety, use ptrace(2).
• Add ulpatches that already patched symbols to task symbols.
• Support uninitialized variable yet, see .bss SHT_NOBITS
• ULPatch VMA better isn't file map

Further

• Support static executable ELF (no need to any dynamic libraries).
• Support sign and check.
• How to patch to strip ELF process.
• loongarch64 support.
• GUI support, like GTK/Qt, etc.
• Like kernel module has module_init and module_exit, ULPatch should has too, if create thread and thread callback is in ULP vma, during unpatch, segvfault will be triggered.
• Support capstone to show ULPatch assembler.

No support (ideal is plump, reality is bony)

• Anon vma for each patch and use prctl(2)(CONFIG_ANON_VMA_NAME) set vma's name, and I try to submit kernel patch, but David Hildenbrand don't like it, see LKML Link
• Maybe we could use dlopen/dlsym to map ulpatch file.
