F6 Targeted Hardening: TLS Handshake-Message Reassembly

Phase: F6 (targeted hardening) — verification and test additions only
Cycle: fix-tls-clienthello-frag
Branch: fix/f6-tls-hardening
Base: develop @ 8b52046
Severity: N/A — no bug fix; this is formal verification gap-closure

This PR closes the F6 targeted-hardening loop for the TLS handshake-message carry-reassembly
logic introduced in STORY-144 (ClientToServer) and STORY-145 (ServerToClient). Production logic
was frozen at F5 convergence and confirmed sound; this PR adds only verification artifacts and
mutation-gap tests. Zero production-code changes (git diff origin/develop src/ = 0 lines
except #[cfg(kani)]-gated proof code that the stable build never compiles).

Verification Evidence

Kani Formal Proofs (VP-039)

Three harnesses in src/analyzer/tls.rs #[cfg(kani)] mod kani_proofs_vp039. Gated behind
#[cfg(kani)] — the stable toolchain build never compiles this code. All proofs non-vacuous
(DF-KANI-NONVACUITY-001 satisfied via kani::cover! annotations).

Harness	Property Proved	Bound	Status
`verify_drain_loop_cursor_safety`	Cursor in-bounds at every loop iteration; no OOB index; no `usize` underflow on `carry.len() - consumed`; drain range `consumed <= carry.len()` always valid; loop terminates. Non-vacuous: dispatched≥1, iters≥2, Decision-4 path, partial trailing, full consumption all covered.	N=12, `#[kani::unwind(5)]`	VERIFICATION SUCCESSFUL
`verify_no_usize_overflow_on_advance`	`consumed.checked_add(4 + body_len)` never wraps for any `consumed ≤ MAX_BUF`, `body_len ≤ MAX_BUF`. Non-vacuous: advance both ≤ and > MAX_BUF reached.	Symbolic full-range	VERIFICATION SUCCESSFUL
`verify_carry_bounded_after_append`	Step-1 pre-append add `carry_len_before + payload_len` does not overflow; carry never exceeds `MAX_BUF` after append. Non-vacuous: clear path, append-below-cap, and exact-MAX_BUF all covered.	Symbolic full-range	VERIFICATION SUCCESSFUL

Aggregate: 3/3 harnesses VERIFICATION SUCCESSFUL, 0 failures, 0 counterexamples.

Fuzz Testing

New target fuzz/fuzz_targets/fuzz_tls_reassembly.rs added to fuzz/Cargo.toml.

Exercises TlsAnalyzer::on_data (both C2S and S2C), try_parse_records, and summarize() on
fully-arbitrary byte sequences sliced into variable-length segments, alternating direction to
force cross-segment carry reassembly. A panic / OOB / arithmetic-overflow / OOM anywhere is a
fuzz finding.

Metric	Value
Executions	1,900,000
Crashes / panics / OOM / timeouts	0
Corpus entries	826
Crash artifacts	none

Verdict: PASS — 0 crashes in ~1.9M executions.

Run command: cargo +nightly fuzz run fuzz_tls_reassembly -- -max_total_time=180 -rss_limit_mb=2048

Mutation Testing (mod f6_hardening)

The F5 convergence mutation run identified 13 real-gap surviving mutants across 6 symmetric
C2S/S2C themes in src/analyzer/tls.rs. All 13 were confirmed genuine (non-equivalent) by
manual mutation re-verification.

Post-F6-hardening result: 100% of real-gap mutants CAUGHT.

Theme	Mutation sites	Description	Tests added
1	C2S `829:64` / S2C `998:64`	Step-1 boundary: `>` → `>=` falsely rejects exact-MAX_BUF fill	`test_BC_2_07_039_c2s_step1_exact_max_buf_accepted`, `test_BC_2_07_041_s2c_step1_exact_max_buf_accepted`
2	C2S `829:41` / S2C `998:41`	Step-1 semantics: additive (not multiplicative) overflow guard	`test_BC_2_07_039_c2s_step1_additive_not_multiplicative`, `test_BC_2_07_041_s2c_step1_additive_not_multiplicative`
3	C2S `900:37` / S2C `1036:37`	Decision-4 body_len spoof guard: `>` boundary	`test_BC_2_07_038_c2s_decision4_body_len_max_buf_not_spoof`, `test_BC_2_07_041_s2c_decision4_body_len_max_buf_not_spoof`
4	S2C `1079:59`	Parse-error discrimination: non-ServerHello message type not accepted as ServerHello	`test_BC_2_07_041_s2c_parse_errors_inc_ok_non_server_hello_v13draft18`
5a	S2C `1029:70`	High-byte body_len lane: `<< 16` (correct) vs `>> 16` (mutant)	`test_BC_2_07_041_s2c_body_len_high_byte_shift_left_not_right`
5b	S2C `1030:67`	Mid-byte body_len lane: `<< 8` (correct) vs `>> 8` (mutant)	`test_BC_2_07_041_s2c_body_len_mid_byte_shift_left_not_right`
6	C2S `911:38` / S2C `1047:38`	Partial-trailing carry retention (incomplete body waits for next record)	`test_BC_2_07_038_c2s_incomplete_body_partial_trailing_carry_retained`, `test_BC_2_07_041_s2c_incomplete_body_partial_trailing_carry_retained`
Buffer sat.	S2C `1155:43`	Exact-fill no spurious drop (buffer saturation BC-2.07.043)	`test_BC_2_07_043_s2c_exact_fill_no_drop`

2 provably-equivalent survivors remain at tls.rs:950:59 (C2S Ok(non-ClientHello) arm).
Documented as structurally unreachable: the Ok path at that site can only return a
ClientHello or Err; a non-ClientHello Ok is dead code. These are accepted; no gap.

Methodology note: cargo-mutants must run at --jobs 1 or low concurrency on this suite.
At --jobs 8, load-induced timeouts mask survivors as ambiguous. Serial run is authoritative.

Security Review

Result: APPROVE — security-reviewer completed full manual review of the PR diff.

CWE-400 (Uncontrolled Resource Consumption) is the primary risk for the TLS carry-reassembly
logic. This PR MITIGATES it: the three Kani proofs formally cover the Step-1 pre-append overflow
guard, the Decision-4 body_len-spoof guard, and the cursor-advance arithmetic. The fuzz harness
covers both C2S and S2C directions with the buffer-saturation tail-drop path. Production guards
at tls.rs:829/998 (Step-1) and tls.rs:900/1036 (Decision-4) remain unchanged and were formally
verified. Zero new attack surface — all additions are test/verification artifacts.

Advisory findings (non-blocking):

SEC-001 (LOW, CWE-697): Kani drain_loop_model Decision-4 branch omits carry.clear() and overflow counter increment — documentation gap only. Production safety is preserved; post-loop drain is guarded by !decision4_fired in both model and production.
SEC-002 (LOW, CWE-682): wrap_handshake_record test helper lacks debug_assert!(len <= 0xFFFF). No current caller passes >65535 bytes; deferred as a future guard improvement.

Risk Assessment

Dimension	Assessment
Blast radius	Minimal — Kani code is `#[cfg(kani)]`-gated (not compiled by stable); tests are CI-only; fuzz target is a separate crate
Production code changes	Zero — `git diff origin/develop src/analyzer/tls.rs` shows only new `#[cfg(kani)]`-gated block
Regression risk	None — new tests can only detect regressions, not introduce them
Breaking change	No — public API surface unchanged
Performance impact	None — tests + proofs run in CI / dev; not in production binary

Rollback: git revert f284c09 fabaf40 07865cb d085db2 if any test proves problematic.

Pre-Merge Checklist

…nts output (F6)

…6 C2S/S2C themes) Adds mod f6_hardening (11 deterministic tests) to tests/tls_analyzer_tests.rs to close 11 of the 13 surviving mutation-testing gaps identified in the TLS handshake- reassembly delta (STORY-144/145/146, Phase F6). One site is unkillable: C2S 950:59 `Ok(_)` arm is dead code (parse_tls_handshake_msg_client_hello always wraps success in ClientHello; Ok(non-ClientHello) for msg_type=0x01 cannot occur). Themes covered: Theme 1 (C2S 829:64, S2C 998:64 >→>=): exact-MAX_BUF accumulation accepted Theme 2 (C2S 829:41, S2C 998:41 +→*): 4+18432 vs 4×18432 arithmetic distinguisher Theme 3 (C2S 900:37, S2C 1036:37 >→>=): body_len==MAX_BUF not triggering Decision-4 Theme 4 (S2C 1079:59 +=→-=,+=→*=): parse_errors+1 via ServerHelloV13Draft18 Theme 5 (S2C 1030:67 <<→>>): body_len high-byte <<16 vs >>16 lane Theme 6 (C2S 911:38, S2C 1047:38 -→+): partial-trailing carry retained after consumed>0 Theme 6c (S2C 1155:43 >→>=): S2C exact-fill no-drop (mirrors C2S EC-005) All 11 new tests GREEN; full suite passes (0 failures); clippy clean; fmt clean.

…7 <<8→>>8) Adds test_BC_2_07_041_s2c_body_len_mid_byte_shift_left_not_right to mod f6_hardening. The previous Theme-5 test pinned the HIGH-byte lane (1029:70 <<16→>>16); the actual surviving mutant was the MIDDLE-byte lane (1030:67 <<8→>>8). body_len = 384 = 0x000180 (middle byte 0x01 ≠ 0). Delivers 387 bytes (one short of a complete 384-body message). With correct <<8: body_len=384, 387 < 388 → incomplete, carry retained at 387. With >>8 mutant: body_len=128, 387 ≥ 132 → dispatched, carry drained. Assertions: server_hs_carry_len==387 AND parse_errors unchanged. All 12 mod f6_hardening tests GREEN; full suite passes (0 failures); clippy clean (manual_repeat_n fixed); fmt clean.

Post-squash, `develop` will report `version = "0.11.1"` in `Cargo.toml`, matching `main` and the published crate tag `e8a8a2d`. - **Rollback:** If this PR is reverted, `develop` returns to showing `0.11.0` — no functional consequence, but the version divergence finding B1 would reopen. --- ## AI Pipeline Metadata - Pipeline mode: Gitflow back-merge (maintenance operation) - Source: `chore/backmerge-v0.11.1` HEAD `2f91829` - Base: `develop` @ `52907bc` - Merge strategy: squash (required — `develop` has `required_linear_history`) - Release tag: `e8a8a2d` (v0.11.1 on `main`, GitHub Release published) - Upstream PRs (all merged): #341, #343, #344, #345, #346 --- ## Pre-Merge Checklist - [x] Diff verified: exactly 3 files (Cargo.toml version, Cargo.lock version line, CHANGELOG.md) - [x] No code changes — version metadata + documentation only - [x] All upstream feature PRs merged to develop (#341, #343, #344, #345, #346) - [x] `develop` CI confirmed green @ 52907bc (2232 tests, clippy, fmt, audit, deny, pin-gate) - [x] Branch pushed to remote: `chore/backmerge-v0.11.1` @ `2f91829` - [x] PR title follows semantic PR convention: `chore: back-merge v0.11.1 release into develop` - [x] Base branch: `develop` - [x] Merge strategy: squash (consistent with project convention + required_linear_history) - [ ] CI green on this PR (awaiting CI run) - [ ] pr-reviewer approval
