It advances the original C05/V03 dependency path. **Complete C05, complete V03, an effective GCC configuration, original execution, source/stage admission and runtime qualification remain open.** + +The original C05 requirement is a complete independently justified project/system-header, search, macro, compiler/specs, linker and dependent-library witness closure in bounded `source_files`. The original V03 recipe is to corrupt each pinned C/header or swap role/header/mode, reject through the original literal/custody route, and preserve the first reached rejection. Neither is replaced by these helper tests or an empty prebuild read-set. + +## Implemented and checked + +- The GCC model authenticates162 selected text inputs, interprets a bounded Make-data subset without invoking Make or shell functions, projects exact patch contexts in memory, and records configured-rule candidates and unknowns.94 selections are definite under its stated source-build values and four remain conditional. `construct_effective_configuration` deliberately raises `IncompleteConfiguration`; it cannot issue completeness from a supplied chain. +- The header extractor authenticates bytes, handles strict-C11 lexical ordering and literal include/probe edges, preserves include-next origin identity and records PCH and unsupported syntax obligations. It does not discharge configured roots or physical namespace facts. The repaired829-occurrence corpus has1,452 literal edges,705 supported and124 unresolved occurrences, with666 conservative frontier forms. The original six occurrences have20 edges and no reported frontier. This is the acquired package corpus, not a reached C05 inventory or evidence that every form causes a read. +- The ELF extractor authenticates supplied bytes and derives interpreter/dynamic dependency edges, preserving order/multiplicity and refusing ambiguous range mappings. The passive original-input observation records25 ELF inputs, five archive/script handoffs and52 ordered NEEDED occurrences. Loader search, aliases and full transitive resolution remain open. CI uses synthetic bytes and does not repeat host observations. +- The V03 generator retains the exact original producer prefix through independent dependency comparison, before either build. All eight original gate literals remainNone. The fixture constructor provides89 proposed DATA cases per profile:68 intended negatives,20 positive discriminators and one earlier-refusal trap. Those are not original control executions or a retroactive funded census. +- The complete refusal corroborator derives the actual f5Root/entry/selected-driver/prefix/terminal source frames. It requires exact frame/source-line structure and a standard contiguous caret range. The older API remains explicitly terminal-site-only. Both require a genuine parent's source/stream ownership and cannot mint admission. + +Registered new-code controls run seven V03 test methods,34 header methods,23 GCC methods and25 ELF methods in normal and optimized Python. The V03 methods include all89 constructor DATA cases and fresh owned byte/mode fixtures. Original Root/provider/helper/C/native sources are read as inert text/bytes only. `genuine_launch` returns launch DATA; no target launch occurs. + +## Retained review corrections + +Independent Sol Max review found and the final source repairs retain: + +1. A heading/final-frame/final-exception three-line traceback passed the initial Pro corroborator. Its old API is now documented narrowly; the complete source-frame API rejects it. A malformed separated caret group was also rejected after review. +2. `#define P(a) 0 ## a ## include` can split around a multi-token argument and synthesize `__has_include`. The header extractor now refuses an interior formal argument unless a stronger model is supplied. The rescan increased conservative unsupported forms from557 to666; earlier receipts remain historical locally. +3. A no-final-newline marker following completed hunk counts bypassed the patch helper's rejection. The helper now refuses that marker throughout the selected target section. No impact was found on the23 retained current projection digests. + +Tests, source identity, independent agent review, independent human acceptance and original qualification are separate. The new scanner's output limits do not prove a bound on every intermediate token/paste-analysis cost. No full resource-fit claim is made. + +## Sources and provenance + +Base `7c49fe32c55de02c2c873655c804b16e4c3fef0a`; canonical handoff [PR6321](https://github.com/CrocSwap/integer-mult-bounds/pull/6321).

Saved buildinfo/changes checksums match GCC/cpp/libgcc-dev/binutils package bytes; six executable members match original pins. No OpenPGP signatures or reproducible builds were independently verified. Python's official development payload independently reproduces215 original header hashes. libc6-dev and Python do not have the same reviewed publisher-build checksum chain. These associations do not establish complete applied configuration or semantics. + +Selected source/configuration text is committed for cold helper replay. The complete source/package archives and823-header corpus payloads are external public inputs described by the exact acquisition/payload manifests in `evidence/`; their full acquisition is not a registered CI command. Captured corpus observations are byte-checked here.

No original compiler, Root, provider, helper, archived module, native control, subprocess, build, or scientific workload was executed. There is no original activity or runtime qualification credit. + +## Input and output contract + +`extract_header_edges(data, SourceOccurrence(...))` takes immutable bytes and checks their exact declared SHA256 and size. The occurrence has an absolute logical pathname, a distinct occurrence identifier, acquisition provenance, and the exact originating search-position identity when known. Equal-byte occurrences remain distinct. An optional `is_primary_source` premise records whether GCC's primary-source `#include_next` override applies. A byte hash authenticates those supplied bytes; it does not itself authenticate their pathname, alias, originating position, ownership or observation interval. Output explicitly says so. + +The extractor returns literal `include`, `include_next`, `__has_include` and `__has_include_next` requests, unsupported frontier records, and separate lexical diagnostics. Filename and directive physical line numbers are distinct when splicing separates them. Every syntactically present conditional branch is scanned without evaluating guards. This yields a potential edge superset. It asserts neither that a request executes nor that it succeeds. A `lookup_only` probe does not entail header-content consumption. + +An empty unsupported frontier means that the bytes lie in the supported lexical language under the premises below. It is not a transitive-header certificate. The caller still must process every discovered selected header occurrence, including each distinct `include_next` origin; supply the exact configured search relation; resolve negative lookups and aliases; account for PCH; and meet namespace/currentness obligations. + +## Supported-language theorem and premises + +For a family of authenticated source occurrences, assume: + +1. The exact strict-C11 GCC frontend uses the selected source's ASCII-compatible input conversion, trigraph table, phase ordering and directive recognition semantics; exact Ubuntu applied-source correspondence remains a separate obligation. +2. Initial builtin and command-line macro state introduces no file-producing operator, nonliteral include operand, pragma, or assembler construct outside the scanned input family. Relevant configured preincludes and macro inputs are independently expanded into that family. +3. Every reachable occurrence has an empty unsupported frontier, and any caller-supplied external macro replacement lists satisfy the same special-operator/paste restrictions. +4. The compiler recognizes file-producing preprocessing operations only through the source forms covered below; other toolchain phases are independently covered by their own rules. + +Then every header-lookup spelling arising through a supported literal include directive or literal probe in an executed guard is among the extracted requests for its occurrence. Proof: phase 1 converts trigraphs before phase 2 removes escaped newlines, including within comments and strings. The lexical scan excludes comments, character constants and ordinary string literals from directive/operator recognition, while respecting header-name contexts. A directive name is lexed without macro expansion. Every source directive that can load a header therefore appears in the scan. Its filename is either the literal that is emitted or an explicit frontier. Both arms of every conditional are visited, so guard values cannot hide an active literal directive. Macro expansion cannot create a new preprocessing directive. A special builtin produced by macro expansion must either already occur as a literal identifier in a replacement/input token stream, in which case it is scanned, or be assembled by token pasting. Paste assessment either proves its fixed fragments cannot make any special file operator or creates an explicit frontier. + +The restricted header spelling alphabet is ASCII letters, digits, underscore, dot, slash, plus and hyphen. No filename is unescaped, lexically normalized, resolved, or opened. In particular `..` and absolute names retain their literal spelling; namespace resolution belongs to the caller. Other spellings are reported explicitly. Valid UTF-8 multibyte bytes in comments and ordinary string/character literals cannot introduce ASCII syntax under the input-conversion premise; bytes outside those contexts create a frontier. + +The ordinary lexical language supports block/line comments, escaped characters in ordinary strings/chars, multiline block comments inside directives, strict-C11 trigraphs, direct backslash-newline splicing, CRLF/bare-CR line endings, `#` and `%:` directives, literal includes and literal probes. Macro-computed include/probe operands, unknown directives, malformed lexical/conditional forms, relevant pragma forms, `_Pragma`, assembler tokens, non-ASCII/UCN identifiers, and GCC whitespace-before-newline splice extensions create explicit frontiers. Missing final newline is deliberately unsupported despite GCC's recovery behavior. + +`#pragma once` and `#pragma GCC system_header` are supported as non-file-producing diagnostics: selected libcpp bodies change once/system-header state and do not load an extra file. Conservative traversal may visit additional skipped content. Other pragmas remain unproved rather than being assumed irrelevant. Literal `_Pragma` and assembler tokens are conservatively refused even when their actual use might only alter warnings or symbol labels. A frontier is a missing supported-language argument, not evidence that its form actually caused an omitted file read. + +## Token pasting refinement + +The first broad census conservatively refused every `##`, dollar identifier, pragma and conditional nesting beyond 24. It is retained unchanged in `c05_header_edges_corpus_summary_v1.json` and `c05_header_edges_corpus_v1_000.json` through `_002.json`. Its 988 forms in 145 occurrences are historical diagnostics, not a demonstrated set of file dependencies. + +The refined scanner distinguishes token pasting that could synthesize a special operator from pasting whose fixed fragments make that impossible. For each contiguous paste chain in a macro definition it treats formal parameters as arbitrary fragments, including empty placemarkers, and fixed adjacent tokens as their literal spelling. It overapproximates possible concatenations by a regular expression. For every completed left paste prefix, if that expression cannot equal `_Pragma`, `__has_include`, `__has_include_next`, `asm`, `__asm` or `__asm__`, the chain is a diagnostic. Otherwise it is an unsupported potential synthesized-file-operator frontier. This analysis deliberately overapproximates actual argument validity and correlations. + +For example, `__GLIBC_USE_ ## F` cannot make any listed identifier; it does not obstruct the header edge theorem. `a ## b` can. The discriminating fixture defines `CAT(a,b) a##b` and uses `CAT(__has_,include)("hidden.h")` in a guard. Removing all token-paste frontiers without an equivalent argument would miss this potential lookup. Unscanned initial macro definitions and exact builtin recognition remain premises. + +GCC's default `dollars_in_ident=1` permits dollar identifiers. They cannot introduce a different ASCII special operator by themselves, so they are diagnostics rather than header-edge frontiers. The acquired package corpus includes a Fortran include with `!GCC$` forms; the corpus scan does not assert that this file is reachable in the original C11 commands. + +## Source argument + +All source references below are selected upstream GCC 13.3.0 base bytes retained under `source-artifacts/gcc-base-selected/libcpp/`. They do not independently discharge exact Ubuntu patch/configuration applicability. Sizes and SHA256 identities appear in the refined corpus summary and the named macro-source identity record. + +- `init.cc:64-69` supplies all nine trigraph replacements; the language table at `106-115` enables trigraphs for STDC11; `139-155` installs those options. `216` enables dollar identifiers. `434-438` registers include probes and `_Pragma` builtins. +- `lex.cc:936-1078`, `_cpp_clean_line`, performs trigraph conversion and escaped newline handling, normalizes CRLF/bare CR, and recognizes the whitespace-splice extension. The implementation flags that extension explicitly rather than treating it as ordinary supported C11. `1828-1915` supports block and line comment behavior, including cleaning lines inside multiline comments. `2808-2900`, `lex_string`, distinguishes strings/chars/header names and makes include-context terminators unescapable. +- `directives.cc:436-490`, `_cpp_handle_directive`, obtains a directive name using `_cpp_lex_token`. `773-833`, `parse_include`, explicitly permits filename macro expansion and copies header spelling; this implementation handles direct literals and refuses computed operands. `839-885` stacks the include; `895-923` distinguishes include/import/include-next, including primary-source include-next fallback. `1584-1593` handles once; `1748-1761` handles system-header; `1765-1790` demonstrates dependency pragmas can inspect another file. `1843-2015` processes `_Pragma` strings. +- `files.cc:1028-1064`, `search_path_head`, uses current `file->dir->next` for include-next, normal behavior for no-search-path/absolute origins, and different quote/angle heads. `2140-2154` routes header probes through that same search operation and preserves the distinction `err_no != ENOENT`, so the planner never collapses all errors into absence. +- `files.cc:275-350` appends `.gch`, may inspect a directory of PCH candidates and validates candidates. `377-432` intercepts ordinary opens through PCH handling. `pch.cc` is retained as supplementary PCH source, but this implementation does not parse or validate PCH inputs. +- `charset.cc:63-81` defines the internal ASCII-compatible source charset on this target; `2834-2945` covers input conversion/BOM handling. BOM/non-ASCII syntax is not silently adopted by this restricted scanner. + +`macro.cc:388-448` parses literal probe operands and routes include-next probes directly through `IT_INCLUDE_NEXT`, without the primary-source directive override; `927-985` spells/concatenates adjacent tokens, lexes the result from stage 3, and retains the successful left spelling on failure; `995-1065` completes paste chains in order. `1903-1945` uses unexpanded arguments adjacent to pastes, and expands arguments before ordinary insertion only when they are neither stringified nor pasted. These bodies corroborate the fixed-fragment overapproximation. The exact passive copy identity is `c05_header_edges_macro_source_v1.json`. + +## Search planning and remaining closure obligations + +`plan_literal_candidates` accepts `ConfiguredSearchPremise` containing exact head/successor position identities. These are caller premises, never a supplied completeness verdict. It preserves order and includes the source directory for ordinary quoted lookups when required. Include-next uses the actual originating position, even if directory strings repeat; primary-source include-next uses normal search. Absolute header spelling bypasses directory concatenation. Every candidate carries an unresolved `.gch` obligation. No lookup is performed and no candidate is declared present, absent, canonical, deduplicated or selected. The supplied chains must already reflect exact configured rules, aliases and identity deduplication. `full_C05` stays false. + +The limits are original caps: 512 edge/frontier/diagnostic rows per extraction, 64 MiB per input file, 256 MiB per capture, plain depth 24, 65,536 nodes, 8192 characters per string, 524,288 aggregate text, 1024 entries per sequence/mapping, and 1 MiB raw records. Plain-value limits are checked by `validate_plain`. A row overflow creates an explicit incomplete-frontier record; plain serialization overflow refuses rather than silently truncating. This module does not measure or certify an actual custody capture. The passive diagnostic corpus is 829 occurrences and therefore is not claimed as one admissible 512-row C05 inventory; its reports are divided into independently bounded plain records. + +The actual reached subset, configured search roots/defaults/builtins, observed names and errors, PCH candidate contents/validation, directory-identity deduplication, alias handling, immutable namespace mechanism and owning-parent/currentness interval remain integration work. Other driver/assembler/linker/loader inputs remain under their separate constructors. No generic worklist or caller `complete=true` flag is accepted as a proof of `W(D,Gamma) subset I`. + +## Verified diagnostic results + +The final refined passive scan authenticated all 829 acquired occurrences (6,208,998 bytes), extracted 1,452 literal requests, and preserved exactly 20 requests across the six original occurrences with no unsupported form in those six. The final refined corpus has 557 conservative frontier forms in 121 occurrences. Counts: 417 unproved pragma forms, 111 assembler forms, 20 potentially synthesized operators, 8 `_Pragma` forms and 1 missing final newline. Every form is located by retained-file identity, logical pathname, physical line and exact original byte-line spelling in the four `c05_header_edges_refined_corpus_v1_*.json` chunks. These are potential syntax obligations, not 557 demonstrated file reads. No macro-computed filename occurs in these acquired bytes under this scan; that observation alone does not discharge the unacquired reached subset. + +Concrete examples include `/usr/include/x86_64-linux-gnu/sys/cdefs.h:131` (`#define __CONCAT(x,y) x ## y`), its line 653 (`# define __glibc_macro_warning1(message) _Pragma (#message)`), and `/usr/include/python3.12/pyport.h:341` (`#define _Py_COMP_DIAG_PUSH _Pragma("GCC diagnostic push")`). The last forms may be provably non-file-producing with a separate pragma expansion/registration argument; this implementation does not silently adopt that argument. `/usr/include/features.h:188` is now a proven non-file-operator paste diagnostic under the stated paste theorem, not a frontier. + +The fresh standard-library fixture suite contains 33 passing tests. It imports only the adjacent new extractor. It checks inactive branches, comment/string/character masking, multiline block comments inside directives, trigraph-before-splice semantics, literal probes and presence tests, computed filename and builtin alias refusals, safe/unsafe paste discrimination, later paste failures, explicit VA_OPT refusal, source byte authentication, equal-byte occurrence identity, row/plain caps, quote/angle order, include-next origin identity, primary-source fallback, absolute-name preservation and unresolved PCH obligations. The final saved test log and receipt pin the exact files. diff --git a/research/h25-c05-v03-input-constructors/implementation/c05_header_edges_macro_source_v1.json

Furthermore, the "basic character set" (listed in + 5.2.1p3) is to be encoded in each with values one byte wide, and is + to appear in the initial shift state. + + It is not explicitly mentioned, but there is also a "wide execution + character set" used to encode wide character constants and wide + string literals; this is supposed to be the result of applying the + standard library function mbstowcs() to an equivalent narrow string + (6.4.5p5). However, the behavior of hexadecimal and octal + \-escapes is at odds with this; they are supposed to be translated + directly to wchar_t values (6.4.4.4p5,6). + + The source character set is not necessarily the character set used + to encode physical source files on disk; translation phase 1 converts + from whatever that encoding is to the source character set. + + The presence of universal character names in C99 (6.4.3 et seq.) + forces the source character set to be isomorphic to ISO 10646, + that is, Unicode. There is no such constraint on the execution + character set; note also that the conversion from source to + execution character set does not occur for identifiers (5.1.1.2p1#5). + + For convenience of implementation, the source character set's + encoding of the basic character set should be identical to the + execution character set OF THE HOST SYSTEM's encoding of the basic + character set, and it should not be a state-dependent encoding. + + cpplib uses UTF-8 or UTF-EBCDIC for the source character set, + depending on whether the host is based on ASCII or EBCDIC (see + respectively Unicode section 2.3/ISO10646 Amendment 2, and Unicode + Technical Report #16).

We do have to cope with big- and little-endian + variants. + + UTF-16 encoding uses two-byte binary numbers, again in big- and + little-endian variants, for all values in the 00000000-0000FFFF + range. Values in the 00010000-0010FFFF range are encoded as pairs + of two-byte numbers, called "surrogate pairs": given a number S in + this range, it is mapped to a pair (H, L) as follows: + + H = (S - 0x10000) / 0x400 + 0xD800 + L = (S - 0x10000) % 0x400 + 0xDC00 + + Two-byte values in the D800...DFFF range are ill-formed except as a + component of a surrogate pair. Even if the encoding within a + two-byte value is little-endian, the H member of the surrogate pair + comes first. + + There is no way to encode values in the 00110000-7FFFFFFF range, + which is not currently a problem as there are no assigned code + points in that range; however, the author expects that it will + eventually become necessary to abandon UTF-16 due to this + limitation. Note also that, because of these pairs, UTF-16 does + not meet the requirements of the C standard for a wide character + encoding (see 3.7.3 and 6.4.4.4p11). + + UTF-8 encoding looks like this: + + value range encoded as + 00000000-0000007F 0xxxxxxx + 00000080-000007FF 110xxxxx 10xxxxxx + 00000800-0000FFFF 1110xxxx 10xxxxxx 10xxxxxx + 00010000-001FFFFF 11110xxx 10xxxxxx 10xxxxxx 10xxxxxx + 00200000-03FFFFFF 111110xx 10xxxxxx 10xxxxxx 10xxxxxx 10xxxxxx + 04000000-7FFFFFFF 1111110x 10xxxxxx 10xxxxxx 10xxxxxx 10xxxxxx 10xxxxxx + + Values in the 0000D800 ... 0000DFFF range (surrogates) are invalid, + which means that three-byte sequences ED xx yy, with A0 <= xx <= BF, + never occur. Note also that any value that can be encoded by a + given row of the table can also be encoded by all successive rows, + but this is not done; only the shortest possible encoding for any + given value is valid.

It helps log checkers and humans debuggers, even if gnatmake + was invoked via a shortcut intended for human typers. + This part will probably be hard to merge for upstream, as some + distributions provide no "target-gcc-version". + . + Log for bug 903694 carries regression tests for both bugs. +Forwarded: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87777 +Bug-Debian: https://bugs.debian.org/814977 +Bug-Debian: https://bugs.debian.org/814978 +Bug-Debian: https://bugs.debian.org/856274 +Bug-Debian: https://bugs.debian.org/881938 +Bug-Debian: https://bugs.debian.org/903694 +Author: Ludovic Brenta +Author: Nicolas Boulenguez +Author: Svante Signell +Author: YunQiang Su + +--- a/src/gcc/ada/osint.ads ++++ b/src/gcc/ada/osint.ads +@@ -144,14 +144,10 @@ package Osint is + -- path) in Name_Buffer, with the length in Name_Len. + + function Program_Name (Nam : String; Prog : String) return String_Access; +- -- In the native compilation case, creates a string containing Nam.

The sanitizer libraries do not depend on libcrypt, so it can happen that during sanitizer library initialization, no real implementation will be found because the crypt, crypt_r functions are not present in the process image (yet). If its interceptors are called nevertheless, this results in a call through a null pointer when the sanitizer library attempts to forward the call to the real implementation. +> +> Many distributions have already switched to libxcrypt, a library that is separate from glibc and that can be build with sanitizers directly (avoiding the need for interceptors). This patch disables building the interceptor for glibc targets. + +Let's remove crypt and crypt_r interceptors (D68431) to fix issues with +newer glibc. + +For older glibc, msan will not know that an uninstrumented crypt_r call +initializes `data`, so there is a risk for false positives. However, with some +codebase survey, I think crypt_r uses are very few and the call sites typically +have a `memset(&data, 0, sizeof(data));` anyway. + +Fix https://github.com/google/sanitizers/issues/1365 +Related: https://bugzilla.redhat.com/show_bug.cgi?id=2169432 + +Reviewed By: #sanitizers, fweimer, thesamesam, vitalybuka + +Differential Revision: https://reviews.llvm.org/D149403 +--- + .../sanitizer_common_interceptors.inc | 37 ------------------- + .../sanitizer_platform_interceptors.h | 2 - + .../sanitizer_platform_limits_posix.cpp | 8 ---- + .../sanitizer_platform_limits_posix.h | 1 - + 4 files changed, 48 deletions(-) + +--- a/src/libsanitizer/sanitizer_common/sanitizer_common_interceptors.inc ++++ b/src/libsanitizer/sanitizer_common/sanitizer_common_interceptors.inc +@@ -10187,41 +10187,6 @@ INTERCEPTOR(SSIZE_T, getrandom, void *bu + #define INIT_GETRANDOM + #endif + +-#if SANITIZER_INTERCEPT_CRYPT +-INTERCEPTOR(char *, crypt, char *key, char *salt) { +- void *ctx;
