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>	2026-11-09 21:42:53 +08:00
3 people	f21fda0fc0	feat(elf): report a Linux kernel image's version banner and embedded build config (#9573) ... * feat(elf): report a Linux kernel image's version banner and embedded build config inspect_kernel_build_config and inspect-kernel-build-config read one local vmlinux, raw arm64 Image, gzip bzImage or zImage, or configs.ko and report its Linux version banner and the IKCONFIG .config embedded between IKCFG_ST and IKCFG_ED, without executing it. A config is present only when a gzip member ends exactly at IKCFG_ED, passes its CRC-32 and ISIZE checks and parses as .config text; framing that fails is reported malformed, never absent. bzImage gzip payloads are inflated within a budget and other codecs are named as unsupported, using codec detection now shared with the kernel module parser. The config search, inflate sizes and option counts are bounded, scans honor cancellation, and target-derived text is marked untrusted. * fix(elf): reject a gzip member whose header checksum fails When FHCRC is set, compare the low 16 bits of the header CRC-32 before inflating, so a damaged header no longer yields a present config or an inflated bzImage payload. * fix(elf): detect the bzImage codec inside the declared payload Codec detection now reads the same payload_offset/payload_length slice that is inflated, so bytes past a short payload cannot name its codec. * fix(elf): report a framed config that does not decode as malformed A damaged or cut-off deflate stream between IKCFG_ST and IKCFG_ED was skipped and could end as an absent config with complete coverage. It is now malformed with config_gzip_invalid, and a later valid config still wins. * fix(elf): scan config lines in place and accept long string values Config text is read one line at a time instead of split into an array, and a quoted value is validated before it is decoded once. The 4096-character string cap is removed: Kconfig has no such limit and max_config_bytes already bounds every line, so a long CONFIG_EXTRA_FIRMWARE list is no longer reported as malformed. * fix(elf): let a live cancellation reach the kernel config parser The parser ran synchronously, so an abort raised during parsing could not change the signal before it returned. Inflation now runs on the zlib thread pool and each scan yields to the event loop once per MiB, so the existing cancellation checks observe a real abort. * refactor(elf): carry the refused kernel config budget as a typed fact Budget failures are now KernelBuildConfigBudgetFailure with a knob field, and the provider builds its recovery advice from that field instead of searching the diagnostic message for an option name. * docs(elf): move the kernel build config 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 /kernel-build-config route is unchanged. * fix(elf): yield while checking one long config line A config made of one long quoted value never reached the per-line yield, so the control-byte check, value validation and SHA-256 ran in one synchronous block. Each now works one MiB window per event-loop turn, and the line patterns match only a bounded name prefix instead of the whole value. * fix(elf): return paged config entries that do not pin the decoded text Entry names and values were V8 slices of the whole decoded config, so a one-entry page kept the full text alive. Entries in the returned page are now standalone copies, so retained memory follows the page size. * fix(elf): yield while kernel marker searches find nothing IKCFG_ST, IKCFG_ED and banner searches used one Buffer.indexOf over the rest of the image, so a large image with no marker never yielded. They now search overlapping one MiB windows and yield after each window without a match. * fix(elf): preserve long kernel config names * fix(elf): frame kernel configs by gzip member boundaries --------- Co-authored-by: Matt Van Horn <455140+mvanhorn@users.noreply.github.com> Co-authored-by: morluto <76467478+morluto@users.noreply.github.com>	2026-11-09 21:41:56 +08:00
Matt Van HornandMatt Van Horn	645735fc0f	feat(windows): inspect Shell Link (.lnk) shortcut files (#7859) ... * feat(windows): inspect Shell Link (.lnk) shortcut files Add inspect_windows_shortcut / inspect-windows-shortcut to read one local Shell Link without resolving or executing the target. The report keeps header flags and FILETIMEs, IDList items, LinkInfo volume and network names, StringData, ExtraData including Tracker droid facts labelled derived, and derived observations such as argument length and a minimized ShowCommand. * fix(windows): tighten Shell Link string reads and coverage - Decode counted StringData over its full CountCharacters payload. - Locate LinkInfo string terminators before charging max_string_bytes and before decoding; an unterminated string is a coverage issue. - Mark an IDList without a TerminalID and an out-of-range LinkInfoHeaderSize as partial coverage. - Report arguments_present and argument_length as null when HasArguments is set but the field could not be read. - Derive target_extension from the joined base path and suffix. - Keep ISO dates for FILETIME and UUIDv1 timestamps before 1970. - Retain the completed file snapshot on parse failures. - Reject an empty CLI path before normalization. - Select the shortcut contract from its family in focused tests. - Fixture StringData no longer writes a NUL into the counted payload. * style: format docs index and Shell Link boundary type Apply oxfmt to the two files format:check reports so Static checks passes. * fix(windows): reject network share paths for Shell Link reads inspect_windows_shortcut is advertised as offline, but the Windows path schema admits UNC paths, and lstat on one can contact an SMB server and offer the caller's credentials. Reject UNC, extended UNC, and other host-prefixed device paths in the provider before any filesystem call. Extended drive paths such as \\?\C:\x stay allowed. A mapped network drive cannot be told from a local drive by its path, and the docs say so. * fix(windows): decode Unicode Shell Link file-entry names File-entry items with bit 0x04 of the type byte, such as 0x36, store a UTF-16LE name, but the parser always read it as Latin-1. The read stopped at the first zero byte, so report.exe became r and an IDList-only shortcut reported the wrong target_extension. Read those names as UTF-16LE. * fix(windows): read volume labels by exact Shell Link discriminator VolumeLabelOffset 0x14 selects VolumeLabelOffsetUnicode and is not itself a label offset, and that Unicode field exists for no other value. The parser treated any offset of 0x14 or more as having both, so a Unicode-only label such as "OS" also produced a false ANSI label "O", and an ANSI label stored past 0x14 had its own bytes read as a Unicode offset. Branch on the exact value in parseVolume, the one place that interprets it, and report a VolumeID too short to hold the selected field. The fixture wrote both encodings for a Unicode volume, which hid the false label, so it now writes one. * fix(windows): limit network share rejection to Windows hosts POSIX hosts read repeated leading slashes as one local root, so an accepted selection such as ///tmp/shortcut.lnk is a local file there. Apply the host-prefixed path check only on Windows, and take the platform through the provider constructor so the Windows path forms stay covered on every test host. * fix(windows): compare shortcut icons only against full paths A stored IDList filename or relative path cannot show that an icon at a full path is elsewhere, so the comparison reported a false difference. Report null unless the icon and a recorded target are both full paths, and assert the missing TerminalID issue by code and offset instead of its message. * fix(windows): keep unread ExtraData blocks unknown A walk that stopped before or inside ExtraData still reported the blocks that HasExpString and HasExpIcon expect as absent, though they were never checked for. Report a block as absent only after the TerminalBlock shows the section was read in full. Without one the block stays unknown and coverage stays partial. * fix(native): ignore LNK network provider type unless ValidNetType is set CommonNetworkRelativeLink NetworkProviderType is only meaningful when the ValidNetType flag (0x2) is set. Return null otherwise. * fix(native): accept any ExtraData TerminalSize below 4 as the terminal MS-SHLLINK requires TerminalSize to be less than 4, not exactly 0. Treat 1, 2 and 3 as the terminal block instead of a malformed block. * fix(native): derive shortcut target facts from the stored environment target Include the EnvironmentVariableDataBlock literal target among the target candidates for target_extension and the icon comparison. Variables are not expanded and the target is not opened. * fix(windows-shortcut): keep unexpanded variable paths unresolved in icon comparison A stored environment target such as C:\Users\%USERNAME%\app.exe could be compared as different from C:\Users\Alice\app.exe. Variable-bearing paths are never expanded, so the icon comparison now returns null unless a fixed target matches the icon exactly. * test: drop redundant ok assertion before typed error guard The testing guide asks for the typed error to be thrown before asserting a successful Result value, and says a preceding .ok assertion adds no coverage. * fix(windows): point out-of-range LinkInfo offsets at their field A LinkInfo, VolumeID or CommonNetworkRelativeLink offset that points past its structure was reported at base + offset. With an offset such as 0xffffffff that position exceeds uint32, so the report failed its schema and the service discarded the whole partial result. Report such issues at the offending offset field instead, which keeps every issue offset and coverage.failing_offset inside the file. Cover each LinkInfo offset field in the parser tests and the LocalBasePathOffset case through the stable filesystem service. * fix(windows): require RFC 4122 variant before deriving Tracker UUID facts A version nibble of 1 alone does not identify a version-1 UUID. Also require the clock_seq_hi_and_reserved top bits to be 10, so other GUID layouts keep their raw value and derive no MAC or timestamp. * fix(windows): ignore DeviceNameOffset fields unless ValidDevice is set MS-SHLLINK 2.3.2 says DeviceNameOffset and DeviceNameOffsetUnicode are ignored when the ValidDevice flag is clear. parseNetwork read both regardless, so garbage in those fields became device-name facts or malformed_structure issues. Read the flags once and only read the device name fields when ValidDevice is set. * fix(windows): keep unsupported Tracker headers as raw data Check TrackerDataBlock Length (0x58) and Version (0) before decoding. A block with any other header is retained as raw bytes with a malformed_structure issue, so it no longer yields MAC and timestamp facts under complete coverage. * fix(windows): compare shortcut icon paths by normalized location Collapse "." and ".." segments and repeated separators in the icon comparison as text only, never opening a path. ".." stops at the drive or UNC share root, and \\?\ and \\.\ paths stay verbatim. Join LocalBasePath with CommonPathSuffix as the target and use the bare base only when the suffix is empty, as the network share branch does. Read the selected shortcut with lstat and open only, so a rejected symlink's destination is never resolved. * fix(windows): keep the UNC share in the root after repeated separators normalizePath took the host and the next split part as the UNC root, so \\server\\share\..\app.exe kept an empty share and let .. remove the real share. Drop empty parts before picking the root so paths on different shares stay different. * fix(cli): parse windows shortcut limits as decimals The four inspect-windows-shortcut limit options now go through cliDecimalField like the other inspection commands, so values such as 0x10 are rejected and cliDecimalArguments.test.ts passes. * fix(native): reject linked parents of windows shortcuts A parent directory symlink or junction pointing at a UNC share was followed by the first lstat, since the network check reads only the path text and the symlink rejection covers only the final component. On Windows, lstat each ancestor from the drive root down and reject the path at the first link, before anything follows it. * docs(native): move Windows shortcut guide and add its feature spec Move the Shell Link guide to docs/guides/native/windows-shortcut.md and list it under Native binaries in the site navigation, keeping the /windows-shortcut public route. Update README, translated README, CLI page and authored skill links to the new physical path. Add docs/specs/native/windows-shortcut/ with spec.md, plan.md and tasks.md, as required by docs/development/documentation.md. * fix(native): admit the windows shortcut parent walk On Windows the ancestor link walk ran before the provider's resource admission, so close() could finish while the walk kept calling lstat. Run the walk inside the same admission as the read, and check the caller's signal before each ancestor lstat. * fix(native): walk the effective parents of windows shortcuts The ancestor link walk checked every prefix of the path as written, so C:\alias\..\real\a.lnk was refused when C:\alias is a directory link, although Windows removes alias\.. before opening the file. Walk the ancestors left after removing . and .. components, keeping the caller's spelling, never climbing above an absolute root, and leaving \\?\ paths as written since Windows does not normalize them. * test(native): assert the linked parent as a structured fact The parent link regression matched the phrase "junction, which" in the refusal message, so a wording edit would fail it. Report the linked ancestor as observed.linked_ancestor on the input issue and assert that fact instead of the explanatory text. * test(native): bound the shortcut close gate and release it in finally Race the parent walk lstat acknowledgement against inspection settling with awaitAcknowledgement, then release the gate and join the inspect and close work in finally so a failure reports its cause instead of waiting for the Vitest timeout. * fix(native): walk Windows shortcut parents lazily windowsAncestors built and kept every parent prefix before the first lstat, so a path with thousands of components allocated memory quadratic in its length. It now keeps only the normalized components and yields each parent from a running prefix as the walk reaches it. --------- Co-authored-by: Matt Van Horn <455140+mvanhorn@users.noreply.github.com>	2026-11-09 20:19:44 +08:00
