Description

Currently pwntools does not support parsing coredumps that are from MIPS binaries. Would be nice if it did.

FYI: The current list of architectures supported: pwntools/pwnlib/elf/corefile.py:102

prstatus_types = {
    'i386': elf_prstatus_i386,
    'amd64': elf_prstatus_amd64,
    'arm': elf_prstatus_arm,
    'aarch64': elf_prstatus_aarch64
}

Contributor guide

Research direction
Study the existing corefile support for other architectures (i386, amd64, arm, aarch64) in pwntools/pwnlib/elf/corefile.py. Understand the elf prstatus structure for MIPS by reading MIPS ELF documentation or referencing existing implementations. Add a new entry to the prstatus types dictionary with the correct MIPS prstatus structure, and ensure the coredump parsing handles MIPS registers correctly.
