Utilities to modify Elf binaries to work with PaX hardened kernel. There are several utilities in here, to help you navigate:

Directories src/ scripts/ doc/ test/ are integral parts of the elfix package. These are distributed as one source tarball with make dist run in the top diretory.

• paxctl-ng - C utility for doing XT_PAX and/or PT_PAX markings.
• pypaxctl - python utility for doing XT_PAX and/or PT_PAX markings. Depends on pax.so.
• migrate-pax - python utility for migrating from XT_PAX flags to PT_PAX. Depends on pax.so.
• revdep-pax - python utility for mapping ELF libraries to/from the ELF objects that link against them and migrating PAX flags between them. Depends on pax.so.
• paxmark.sh - Bash script that does intelligent pax-marking like the pax-utils.eclass.
• paxmodule.c - C code for python module pax.so

Directories under misc/ are independant packages from one another and from the elfix package. They are NOT distributed with elfix when running make dist in the top directory. Each directory supplies its own build system.

• install-xattr - C wrapper to coreutils' install which preserves file system extended attributes.
• fix-gnustack - query or clear any ELF GNU_STACK executable flag

Directory pocs/ - Very experimental stuff.

• change-interp - C utility to the dynamic linker, INTERP as reported by readelf -l.
• eclass - a local copy of the pax-utils.eclass
• elf-manipulate - some dirty utilities to
• • clear-dt-path.c - remove RPATH and RUNPATH
• • parse-elf.c - print out the ELF header, sections headers and program headers.
• • print-sections.c - print out the contents of the section headers
• • remove-ptpax.c - change a PT_PAX_FLAGS phdr to PT_NULL
• ldd - python script to reproduce ldd's output using pyelftools
• link-maps - use VDB information to produce a full linkage map of the system
• mangle-paxflags - printout old EI_PAX flags and PT_PAX flags
• paxmark-libs - test how PAX flags migrate from libraries and plugins to their consumers
• revdep-pax-ng - same as revdep-pax but using information obtained from ldd and not VDB information.
