ci(release): fetch full history for accurate commit count

chore(brand): rebrand to TEESimulator-RS with simplified versioning
Fork identity: rename across module metadata, CI pipeline, and build scripts. Version scheme changed from v4.5-115-7e87766 to v4.6-117 format — commit count auto-increments, git hash dropped from filenames.

+## TEESimulator-RS v4.6: Rebrand & Detection Fix
+
+- **RTT normalization rework** — Replaced Gaussian sleep (mean=55ms) with a 15ms floor fence. The old approach triggered Chunqiu Native Check 2.8 timing analysis; the floor-only approach satisfies the minimum RTT threshold without creating a detectable delay pattern.
+- **Cross-algorithm attestation** — Signing algorithm now derived from the attestation key's actual type, not the generated key's algorithm. Fixes BouncyCastle crash when signing RSA keys with EC attestation keys (Shizuku attestation flow).
+- **Device ID attestation** — Serial/IMEI/MEID/secondImei tags now flow through to software cert gen instead of blanket rejection. Only DEVICE_UNIQUE_ATTESTATION is rejected, matching AOSP keystore2 policy.
+- **Rebrand to TEESimulator-RS** — Distinguishes this fork from upstream. Version scheme simplified to v{major}.{minor}-{commitCount}.
+- **CI streamlined** — Release pipeline uses Gradle-generated filenames directly, eliminating the rename step.
+
+---
+
+## TEESimulator v4.5: Detection Hardening
+
+Tested against [KeyDetector](https://github.com/XiaoTong6666/KeyDetector) (23-check attestation validator). All keystore-level checks now pass.
+
+- **Key deletion consistency** — After deleting a software-generated key, `getKeyEntry` now correctly returns `KEY_NOT_FOUND` instead of falling through to a stale live-patch fallback. Fixes binder consistency checks that detect ghost key responses.
+- **generateKey timing normalization** — Software key generation RTT now matches real TEE latency profile (Gaussian distribution, mean=55ms, floor=15ms). Previously completed in ~4ms, which is an immediate timing side-channel.
+- **Delete cleanup scope** — `deleteKey` now clears all cached state (patched chains, attestation keys) regardless of whether the key was software or hardware-generated.
+
+---
+
+## TEESimulator v4.4: AOSP Conformance
+
+- **Binder error reply format** — Aligned EX_SERVICE_SPECIFIC wire layout with AOSP Status.cpp, including the remote stack trace header field.
+- **Key enumeration** — Corrected list_past_alias pagination order to match AOSP database.rs semantics.
+- **KeyMetadata fields** — Generated key responses now include modificationTimeMs, Tag.ORIGIN, and normalized KeyDescriptor fields per AOSP Keystore2.
+- **Parcel handling** — hasException() preserves reply position for downstream consumers.
+
+---
+
 ## TEESimulator v4.3: Performance & Reliability

 - **Debug log gating** — `SystemLogger.debug()` now skipped entirely in release builds, eliminating unnecessary logcat syscalls on every intercepted transaction.

Author	SHA1	Message	Date
Enginex0	23696d2f61	ci(release): fetch full history for accurate commit count	2026-03-17 03:43:16 +01:00
Enginex0	dfacb34cf9	chore(brand): rebrand to TEESimulator-RS with simplified versioning Fork identity: rename across module metadata, CI pipeline, and build scripts. Version scheme changed from v4.5-115-7e87766 to v4.6-117 format — commit count auto-increments, git hash dropped from filenames.	2026-03-17 03:35:32 +01:00
Enginex0	06d9db443c	perf(keygen): replace Gaussian RTT normalization with 15ms floor fence The old Gaussian sleep (mean=55ms, stddev=12ms) triggered detection on Chunqiu Native Check 2.8. A flat 15ms floor satisfies the minimum RTT threshold without creating a detectable delay pattern — both attested and non-attested paths get identical treatment, keeping the D50 ratio at ~1.0 while staying above the >=15ms requirement.	2026-03-17 03:35:20 +01:00
Enginex0	7e87766493	fix(certgen): derive signing algorithm from attestation key and allow device ID tags signerAlgorithm was derived from params.algorithm (the generated key) instead of the signing key, causing BouncyCastle to throw when signing RSA keys with an EC attestation key. Now reads signingKeyPair.private.algorithm. Device ID tags (serial/imei/meid/secondImei) were blanket-rejected instead of flowing through to software cert gen like AOSP does. Narrowed rejection to DEVICE_UNIQUE_ATTESTATION only.	2026-03-17 00:05:56 +01:00
Enginex0	f8bfa0dfd8	fix(attestation): align authorization list and cert extension with AOSP keystore2 semantics toAuthorizations() was missing OS_VERSION, OS_PATCHLEVEL, VENDOR_PATCHLEVEL, BOOT_PATCHLEVEL, CREATION_DATETIME, USER_ID, PADDING, and RSA_PUBLIC_EXPONENT tags that real TEE-generated KeyMetadata always includes. EC_CURVE was also hardcoded unconditionally, producing invalid authorizations for RSA keys. Additionally, live-patched certificate chains in getKeyEntry weren't cached, causing re-patching on every call with potentially different signatures. Ports upstream JingMatrix/TEESimulator#148 and #150.	2026-03-16 23:01:28 +01:00
Enginex0	90ff59e0aa	fix(interception): check generatedKeys before deletedSoftwareKeys on getKeyEntry The deletion guard must not shadow re-generated keys. If an app deletes a key then re-creates it, getKeyEntry was still returning KEY_NOT_FOUND because deletedSoftwareKeys was checked first.	2026-03-16 22:36:02 +01:00
Enginex0	8bdf0d59fa	docs(release): bump to v4.5 with detection hardening changelog	2026-03-16 22:07:56 +01:00
Enginex0	6ab09f4889	fix(interception): prevent ghost key responses after software key deletion After deleting a software-generated key, getKeyEntry was falling through to the real keystore2 service which could return a stale hardware key with the same alias. The post-transact live-patch fallback would then resurrect the key with a patched chain — detectors flag this as binder inconsistency. Track deleted software key aliases and return KEY_NOT_FOUND (7) for subsequent getKeyEntry calls. Also always invoke cleanupKeyData on delete to clear stale patchedChains entries for hardware keys.	2026-03-16 22:06:53 +01:00
Enginex0	f4559bcd19	perf(keygen): normalize software generateKey RTT to match TEE latency Software-generated keys complete in ~4ms, real TEE averages 55-65ms with a floor around 15ms. Detectors measure this RTT to distinguish software from hardware paths. Gaussian delay sampling (mean=55ms, σ=12ms, floor=15ms) brings total RTT into the expected range.	2026-03-16 22:06:38 +01:00
Enginex0	3b5043a1bb	docs(release): bump to v4.4 with AOSP conformance changelog	2026-03-16 13:26:34 +01:00
Enginex0	8001a8678a	fix(interception): absorb upstream correctness fixes and patch error reply format Cherry-pick three upstream fixes: Parcel position reset in hasException() so the method doesn't consume reply data (7804743), list_past_alias enumeration filter inversion (2aac65c), and KeyMetadata alignment with AOSP semantics — modificationTimeMs, Tag.ORIGIN, KeyDescriptor normalization (86db5bf). Additionally, createErrorReply() was missing the empty remote stack trace header int between the exception message and error code, per AOSP Status.cpp:196. Binder readers expecting the standard EX_SERVICE_SPECIFIC wire format would misparse our error replies.	2026-03-16 13:23:36 +01:00
