Walkthrough

SHA 压缩内核、HMAC 实现、验证器和 17 个 IPSec 测试现按运行时 SVE lane 数处理数据，支持 128–1024-bit 向量长度。HMAC 入口增加容量与输入边界检查；文档和验证记录同步更新。

Changes: SVE 全向量长度测试

Layer / File(s)	Summary
SHA 压缩内核的运行时流数 `tests/cpu/sve/ipsec/sve_sha_kernels.h`	SHA-1、SHA-256 和 SHA-512 压缩内核按运行时 lane 数处理消息，并将调度数组扩展到最大流数。
HMAC 流数与输入边界 `tests/cpu/sve/ipsec/sve_hmac.h`	五个 HMAC 函数按运行时 lane 数处理流。入口检查流数、密钥长度和消息长度，并返回错误状态。
SHA 验证器的运行时 lane 处理 `scripts/sve-sha-verify/verify.cpp`	验证器检查支持的 lane 范围，并按运行时 lane 数执行五种 SHA 测试。结果行新增实际 lane 数。
IPSec HMAC 测试的运行时流数 `tests/cpu/sve/ipsec/ipsec__sve.cpp`	17 个 IPSec 测试按运行时 lane 数分配和处理 HMAC 流，检查运行期间的流数变化和 HMAC 错误，并限制消息大小。
全向量长度说明与验证记录 `README.md`, `tests/cpu/sve/meson.build`, `docs/research/progress-log.md`	说明和进度记录更新全向量长度范围、消息大小限制及验证方式。

kTileMax 是本次新增的编译期常量。同文件已有的常量都使用 ALL_CAPS（RADIUS、K_AXIS_CALLS）。建议改名为 TILE_MAX，并同步修改第 164、272、286 行的引用。

[claude] [Important] 内存: HMAC/SHA 内核层对流数维度(n=svcntw()/svcntd())没有任何内部上界守卫,而同一 PR 给同一函数的 key_len 与 padded 两个维度都加了守卫——本 PR 自称的"容量守卫"修复恰好漏掉了同一缺陷类的第三个维度。
证据: sve_hmac.h:33 const int n = (int)svcntw(); 之后 for (int s = 0; s < n; ++s) 直接写 uint8_t ipad_blk[SVE_SHA_STREAMS_MAX_32][64](行35)和 full[SVE_SHA_STREAMS_MAX_32][2048](行64),全文件 grep 无任何 n > SVE_SHA_STREAMS_MAX 检查;对照同函数已存在 if (key_len > 64) return -1;(行40)与 if (padded > 2048) return -1;(行60)。sve_sha_kernels.h 同构:行73/89(sha256 的 n 与 W[64][32])、行196/207(sha512)、行285/296(sha1),且 svst1_u32(pg, out[w], a) 按运行时 svcntw() 写 32 宽的 out 行。当前 17 个测试与 verify.cpp 均在调用方门控 128..1024-bit 故不可达,但框架自测 selftest.cpp:1012 用 arm64_require_sve_vl(test, 128, 2048) 表明 2048-bit 在 contemplation 范围,而 meson 注释明示该头是供复用的 "SVE HMAC layer"——任何未门控的新调用方在 VL>1024-bit 即栈越界写(如 n=64 时向 2048 字节的 ipad_blk 写 4096 字节)。一行 if (n > SVE_SHA_STREAMS_MAX_32) return -1; 即可闭环,与 key_len 守卫(同样当前不可达却已加)标准一致。

+        report_fail_msg("%s: hmac assembly over capacity", test->id);


[claude] [Minor] 正确性: init 侧 HMAC 容量守卫失败经 noreturn 的 report_fail_msg 在 test_init 上下文表现为 Skipped("Unexpected OS error")而非 Failed——真实容量回归会被误报为"未运行",失败类别失真。
证据: 行108 report_fail_msg("%s: hmac assembly over capacity", test->id); 位于 compute_golden,由 test_init 调用(行161);progress-log.md:657 自认:"hmac 容量守卫的 init 侧失败经 report_fail_msg 会表现为 Skipped("Unexpected OS error")而非干净 Failed——knob 钳制后不可达,纯纵深防御,记账"。当前 data_size 钳 1900/1830 < 1975/1903 安全边界故不可达,但若未来放宽钳制,该路径以 Skip 掩盖 Failed;run 侧两处调用点(行257/290)语义正确,仅 init 侧(17 文件各 1 处)误标。

[claude] [Minor] 可维护性: Phase A 标量 golden 硬编码 0.125 字面量,与内核实际消费的 coeff[] 表(另一处独立 0.125 字面量)脱钩——注释写 coeff[r] 而代码写常量,两处失同步时 golden 静默算错。
证据: 行235-237 double coeff[RADIUS + 1] = {}; ... coeff[r] = 0.125; 是 axis_generic_16x2 经 svdup_f64 消费的系数表;行297 expected[jj] += 0.125 * delta; 是 golden 参考的独立字面量,而行276-278 注释却声称 "sum over r of coeff[r] * (s_base[-off+jj] + s_base[+off+jj])"。参考直接读 coeff[r] 即可消除耦合;任一处单独修改(如加宽激发系数)即 golden 与内核失同步。失配方向是误报失败(响亮)而非漏报 SDC,故仅 Minor。

[claude] [Important] 正确性: 17 个测试文件的新门控/布线胶水层（arm64_require_sve_vl 调用、nstreams=svl/4、[4,32] 检查、漂移守卫、容量守卫）在任何 VL 下零执行证据——PR 标题『VL=128 命题实证』的实证对象只是 gem5 sve_sha_dual 内核副本，而非这 17 个测试本身；本机只验证了编译与 SKIP 路径。
证据: progress-log:653-654 自述每文件验证仅为 'TU 零告警+skip 干净(框架编译特性门)+终态全量构建零告警+zstd19 pass'（=编译+宿主机 SKIP 路径，宿主机 0xd01 无 SVE）；:645-648 gem5 证据是 'sve_sha_dual' harness，首轮评审发现的 '&sw[0][s]'、'mini-HMAC' 表明它是 harness 本地精简副本（非同源测试文件）；:655 自认 'verify.cpp 的 5200 向量 OpenSSL 重验需 SVE 硬件(本机仅编译验证)'。即 ipsec_aes128_cbc_hmac_sha1_sve.cpp:121 的 require 调用、:125 的范围检查、:191-195 的漂移守卫、sve_hmac.h 的容量守卫（这些恰是本 PR 新增的安全机制本身）从未在任何硬件/仿真上执行过——而 8.2 缺陷（VL≥512 时想当然的 [8] 定维）正藏在同类的'显然正确'边界代码里。违反 CLAUDE.md 规则 2（宿主不可跑的功能变更须 gem5-fi 验证，禁止以 SKIP 路径顶替功能验证；PR #242 先例）。

[claude] [Minor] 正确性: nstreams 在 test_init 辅助线程上读 VL 派生，而 run 侧 svcntw() 是 worker 线程（继承控制线程）的 VL——两者一致仅靠『线程创建继承』这一未被本测试固化的隐含不变式；一旦部署侧出现 per-thread VL pinning，17 个测试将全线 report_fail_msg 硬失败，而非按新 VL 重新门控或以 CpuNotSupported 跳过。
证据: init 在 :121 调 arm64_require_sve_vl（在 throwaway 辅助线程上 rdvl），:191 守卫 '(int)svcntw() != d->nstreams' 在 worker 线程比对后 report_fail_msg（noreturn，已核实 framework/sandstone.h:457）；而 framework/device/cpu/arm64/arm64_vl.h:19-29 自述硬边界：'ordinary tests run test_init on a throwaway aux thread…workers are created by the control thread and inherit ITS (unpinned) VL. Pin where the VL is needed: inside test_run'。仓库自己的 VL-pinning launcher 先例（scripts/eigen-sve-double，CLAUDE.md 记载）正是改变线程 VL 继承链的部署形态，届时环境不匹配会被记为测试 Failed 而非硬件不支持跳过。

[claude] [Minor] 可维护性: nstreams 上界用硬编码字面量 32/16 而非 SVE_SHA_STREAMS_MAX_32/64 宏，且 n=svcntw() 在每个文件 6+ 处重复推导、与 kernel 内部推导仅靠注释约定——数组维度与检查界限将来会静默失同步，且无任何编译期耦合兜底。
证据: :40 '#define NSTREAM (SVE_SHA_STREAMS_MAX_32)' 用于数组定维，:125 却写 'nstreams > 32' 字面量（64-bit 族 17 文件同型 '> 16'）；:90/:256/:290 三处 'const int n = (int)svcntw(); /* 与 kernel 内部推导一致 */' 各自重读 VL，kernel 内部（sve_sha_kernels.h:79/:202/:291）另有三处独立推导——调用侧缓冲计数与 kernel 内部流数的一致性全靠注释与 :191 的运行时守卫，STREAMS_MAX 若随 2048-bit 支持调整，字面量检查不会跟着变。

[claude] [Minor] 可维护性: 注释保留固定向量数 '5200+1360 vectors' 与 'verified bit-for-bit against OpenSSL' 宣称，而本 PR 自己已把向量数改为随 VL 缩放、且参数化形态（n≠8/4）的 OpenSSL 位级重验从未执行——文档宣称与验证事实不符。
证据: meson.build:300-301 'both verified bit-for-bit against OpenSSL, 5200+1360 vectors, see scripts/sve-sha-verify'；同 PR 的 verify.cpp docblock 新增 'the vector-set size per round scales with the host VL (5200 vectors at VL=256, more at wider VL)'——5200 仅是 VL=256 一档的值；progress-log:655 承认 'verify.cpp 的 5200 向量 OpenSSL 重验需 SVE 硬件(本机仅编译验证)'，即参数化后该 OpenSSL 比对零次执行，注释却继续宣称已验证，违反 CLAUDE.md 规则 7（文档 100% 准确）。

摘要失配的失败现场缺少出错 lane 编号

本 PR 把流数扩展到最多 32 条（64-bit 族最多 16 条）。逐流 memcmp_or_fail 的比对是正确的。但是失败消息 "HMAC-SHA1-96 digest mismatch (frozen replay)" 不包含 s。

路径指令第 7 条要求失败现场记录出错 lane 编号，用于区分单 lane 与多 lane、相邻与跨 lane。当前日志只能看出"某个流失配"。高 VL 下不能直接定位是哪条 lane。

建议在比对前生成带 s 和 d->nstreams 的消息。如果 memcmp_or_fail 支持格式化参数，也可以直接传入。17 个测试的 frozen replay 与 reroll 两处比对都需要同样修改。
