* feat(native): recover ELF function ranges from unwind tables inspect_elf_unwind_ranges and inspect-elf-unwind-ranges read .eh_frame and .eh_frame_hdr from one local ELF32 or ELF64 image and list the function ranges its FDEs name, with CIE facts, LSDA and personality, the containing section and an exact symbol where one starts at the address. Nothing is executed and no disassembler is needed. Pointer encodings follow the DW_EH_PE rules with raw zero as null, discarded FDEs are counted and skipped, the .eh_frame_hdr search table is compared with the decoded FDEs, and record, row and symbol budgets are bounded. verify:elf:unwind-ranges compares the reported starts with llvm-dwarfdump or readelf on a compiled C++ program. * fix(elf): keep unresolved unwind facts out of reported ranges Skip FDEs whose initial location is indirect and do not locate .eh_frame through an indirect eh_frame_ptr, since pointer slots are not functions. Stop an unbounded header-located scan at a CIE with an unrecognized augmentation, report ignored duplicate PT_GNU_EH_FRAME headers as incomplete coverage, and accept a null personality stored under an indirect encoding. Keep only symbols at decoded FDE starts, cache name observations per string-table offset, and decode names only for the returned page under a fixed 16 MiB text allowance, so repeated or long names no longer grow memory with the symbol count. * fix(scripts): run the ELF unwind verifier under owned process trees Launch probes, compiler drivers, the stripper, the frame dump and the inspection through createVerifierCommands, as verify-binary-hardening does, so a timeout or interrupt stops the whole tree. The temporary directory is removed only after the owned commands have closed. * docs(elf): move ELF unwind ranges guide under docs/guides/native The documentation guide assigns analyst workflows to docs/guides/<domain>/. Move the guide there, place its navigation and directory entries in the Native binaries group, and update links from the docs index, CLI guide, spec and authored skill. The public /elf-unwind-ranges route is unchanged. * fix(elf): give unwind text limits their own recovery and skip indirect tables Throw a dedicated failure when a page's symbol names exceed the 16 MiB text allowance, and map it to a resource error that tells the caller to request a smaller limit rather than raise max_ranges. Read a CIE augmentation with one bounded NUL search and keep it as a byte view, decoded only for returned CIEs, so a long augmentation is never built up character by character. Leave an .eh_frame_hdr search table with an indirect encoding unread: the header is incomplete, the comparison is unavailable, and the table no longer bounds a header-located .eh_frame scan. * fix(elf): resolve header count and table forms and name IFUNC resolvers Leave a non-zero .eh_frame_hdr FDE count under an indirect encoding unresolved, since it is the address of a slot that is not followed, and mark the header incomplete without reading the table. Treat a DW_EH_PE_omit table encoding as an omitted search table before testing the indirect bit, so a header that declares a count without a table stays present with complete coverage, and accept that form in output validation. Match STT_GNU_IFUNC symbols at exact FDE starts after function symbols, with a limitation that the name is the resolver, not the implementation it selects at run time. * fix(elf): require allocated unwind pointer bases * fix(elf): map unwind header relative base * fix(elf): validate unwind load mappings * test(elf): cover mapped nonallocated frame agreement --------- Co-authored-by: Matt Van Horn <455140+mvanhorn@users.noreply.github.com> Co-authored-by: morluto <76467478+morluto@users.noreply.github.com>
