Upstream is absorbed by **true merge**, +never by rebase/replay, so every upstream tag remains fully contained in the fork +history and the merge-base keeps advancing on each catch-up. The most recent sync is +upstream **v1.5.6** (`c63c311`, KMREQ heap-overflow hardening, CVE-2026-55868/55869). + +There are exactly **two** functional CeraLive patches to the C/C++ source. Everything +else the fork carries is packaging and CI (documented at the end for completeness). + +--- + +## 1. `SRTO_REORDERFREEZE` — opt-in reorder-tolerance decay freeze + +- **Commit:** `66b3609cc004e6a4c485e0adc11149025e782083` (2026-06-24) + — *feat(core): reset to upstream 1e4c908; add opt-in SRTO_REORDERFREEZE decoupled + from NAKREPORT* +- **Type:** new receiver-side socket option, **default off** (`SRTO_REORDERFREEZE = 120`). +- **Where:** `srtcore/srt.h` (enum), `srtcore/socketconfig.{h,cpp}` + (`CSrtConfig::bReorderFreeze` + setter), `srtcore/core.cpp` (the two decay gates, + each tagged `// CERALIVE reorder-freeze`), `test/test_socket_options.cpp` (tests). + +**Rationale.** SRTLA delivers packets out of order **by design** — bonded traffic is +balanced across multiple links, so a healthy bonded path is naturally reordered. Stock +libsrt runs an adaptive reorder-tolerance *decay* that drives the tolerance toward 0 on +a clean ordered stream; over a bonded path that decay causes spurious retransmissions. +`SRTO_REORDERFREEZE` freezes only the **decay** (it does not touch `initial_loss_ttl`, +is orthogonal to `SRTO_NAKREPORT`, and is a no-op on senders), so a receiver on a +bonded ingest can hold reorder tolerance at max without any of BELABOX's broader C +patches. It is opt-in and inherited by accepted sockets from the listener, so enabling +it on the receive listener propagates to every accepted connection. ADR-002 records +this as the **only** patch needed for BELABOX-parity baseline ("C is SAFE"). + +--- + +## 2. Deterministic socket teardown + +- **Commit:** `293ae6f45bf116c56d056b3a25312b2aade7dade` (2026-07-13) + — *fix(core): make socket teardown deterministic* +- **Type:** correctness/reliability fix to socket close semantics and the test harness + that guards them. +- **Where:** `srtcore/srt_c_api.cpp` (idempotent public close), plus the socket + lifecycle test suite (`test/test_epoll.cpp`, `test_file_transmission.cpp`, + `test_main.cpp`, `test_reuseaddr.cpp`). + +**Rationale.** Makes the public `srt_close` path **idempotent across the bounded +garbage-collector retirement race** — when a valid socket is retired by the GC between +the public state check and the internal close acquisition, close still returns its +existing idempotent-close result instead of racing. It also hardens the test harness to +match: single-owner cleanup (no raw-closing a `UniqueSocket`'s handle), readiness +registered before peer activity, and synchronized file-transfer / IPv6-reuse teardown. +These lifecycle assertions are **required gates** — they must not be relaxed or retried +away (see [`AGENTS.md`](../AGENTS.md) → TEST). The determinism matters on the device +because `cerastream` opens and closes SRT sockets across stream start/stop cycles; a +non-deterministic teardown surfaces as flaky reconnects. + +--- + +## Packaging & CI (non-source CeraLive additions) + +These do not change the SRT protocol or the library ABI; they exist so the fork ships +as the device runtime package. Listed for completeness — they are **not** functional +C/C++ patches. + +- **Device runtime package** — `feat(packaging): ship CeraLive SRT runtime` (`c590cce`) + and follow-ups: `packaging/build-deb.sh` produces `libsrt1.5-ceralive` (GnuTLS + backend, SONAME `libsrt.so.1.5`) which replaces the Debian TLS-flavor packages and + provides their virtual names so one CeraLive `libsrt.so.1.5` ABI loads per process. +- **Bundled SRT sample tools** — `feat(packaging): bundle SRT sample tools into + libsrt1.5-ceralive` (`9b02dc7`): ships `srt-live-transmit` and siblings in the same + package, dynamically linked against the one shipped `libsrt.so.1.5` (single-fork + invariant preserved; verified in `runtime-package.yml` / `publish-release.yml`). +- **CI** — `runtime-package.yml` (package contract + GStreamer replacement gate), + `publish-release.yml` (release + apt dispatch), and bounded ccache coverage across + the upstream test workflows (`ubuntu-c++03.yml`, `ubuntu-c++11.yml`, `macos.yml`, + `windows-msvc-noenc.yml`). See [`AGENTS.md`](../AGENTS.md) → CI COMPILER-CACHE + COVERAGE. + +--- + +## Maintenance rule + +When syncing upstream, keep this file current: a new CeraLive C/C++ patch **must** be +added here with its commit SHA and a one-paragraph rationale, and a patch that is +retired (e.g. superseded by an upstream fix) **must** be moved to a "Retired" note +rather than silently dropped. Any functional change beyond these two patches is out of +scope for the fork (see [`AGENTS.md`](../AGENTS.md) → SCOPE BOUNDARY). diff --git a/docs/apps/srt-live-transmit.md b/docs/apps/srt-live-transmit.md index 48741df23..718508ba0 100644 --- a/docs/apps/srt-live-transmit.md +++ b/docs/apps/srt-live-transmit.md @@ -236,7 +236,7 @@ the presence of the **adapter** parameter: * Caller mode: if you specify *host* part, but not **adapter** parameter: - `srt://remote.host.com:1234` * Rendezvous mode: if you specify *host* AND **adapter** parameter: - - `srt://remote.host.com:1234&adapter=my.remote.addr` + - `srt://remote.host.com:1234?adapter=my.remote.addr` Sometimes the required parameter specification results in a different mode than desired; in this case you should specify the mode explicitly. diff --git a/haicrypt/haicrypt.h b/haicrypt/haicrypt.h index da0ad3493..573efbf3b 100644 --- a/haicrypt/haicrypt.h +++ b/haicrypt/haicrypt.h @@ -106,6 +106,9 @@ int HaiCrypt_Tx_Process(HaiCrypt_Handle hhc, unsigned char *in, size_t in_len, int HaiCrypt_Rx_Process(HaiCrypt_Handle hhc, unsigned char *in, size_t in_len, void *out_p[], size_t out_len_p[], int maxout); +// Length not needed, as long as it's pre-verified that it's at least SALT length. +int HaiCrypt_GetKeyIndex(HaiCrypt_Handle hhc, unsigned char *in); + int HaiCrypt_Tx_GetKeyFlags(HaiCrypt_Handle hhc); int HaiCrypt_Tx_ManageKeys(HaiCrypt_Handle hhc, void *out_p[], size_t out_len_p[], int maxout); int HaiCrypt_Tx_Data(HaiCrypt_Handle hhc, unsigned char *pfx, unsigned char *data, size_t data_len); diff --git a/haicrypt/hcrypt_ctx_rx.c b/haicrypt/hcrypt_ctx_rx.c index 2b67490d3..907acdf09 100644 --- a/haicrypt/hcrypt_ctx_rx.c +++ b/haicrypt/hcrypt_ctx_rx.c @@ -152,24 +152,25 @@ int hcryptCtx_Rx_ParseKM(hcrypt_Session *crypto, unsigned char *km_msg, size_t m return(-1); } + hcrypt_Ctx new_ctx = *ctx; /* Check Salt and get if new */ - if ((salt_len != ctx->salt_len) - || (0 != memcmp(ctx->salt, &km_msg[HCRYPT_MSG_KM_OFS_SALT], salt_len))) { + if ((salt_len != new_ctx.salt_len) + || (0 != memcmp(new_ctx.salt, &km_msg[HCRYPT_MSG_KM_OFS_SALT], salt_len))) { /* Salt changed (or 1st KMmsg received) */ - memcpy(ctx->salt, &km_msg[HCRYPT_MSG_KM_OFS_SALT], salt_len); - ctx->salt_len = salt_len; + memcpy(new_ctx.salt, &km_msg[HCRYPT_MSG_KM_OFS_SALT], salt_len); + new_ctx.salt_len = salt_len; do_pbkdf = 1; /* Impact on password derived kek */ } /* Check SEK length and get if new */ - if (sek_len != ctx->sek_len) { + if (sek_len != new_ctx.sek_len) { /* Key length changed or 1st KMmsg received */ - ctx->sek_len = sek_len; + new_ctx.sek_len = sek_len; do_pbkdf = 1; /* Impact on password derived kek */ } /* Check cipher mode */ - if (ctx->mode != km_msg[HCRYPT_MSG_KM_OFS_CIPHER]) + if (new_ctx.mode != km_msg[HCRYPT_MSG_KM_OFS_CIPHER]) { HCRYPT_LOG(LOG_WARNING, "%s", "cipher mode mismatch\n"); return(-3); @@ -179,21 +180,32 @@ int hcryptCtx_Rx_ParseKM(hcrypt_Session *crypto, unsigned char *km_msg, size_t m * Regenerate KEK if it is password derived * and Salt or SEK length changed */ - if (ctx->cfg.pwd_len && do_pbkdf) { - if (hcryptCtx_GenSecret(crypto, ctx)) { + int rollback_kek = 0; + if (new_ctx.cfg.pwd_len && do_pbkdf) { + if (hcryptCtx_GenSecret(crypto, &new_ctx)) { return(-1); } - ctx->status = HCRYPT_CTX_S_SARDY; + new_ctx.status = HCRYPT_CTX_S_SARDY; kek_len = sek_len; /* KEK changed */ + rollback_kek = 1; } /* Unwrap SEK(s) and set in context */ - if (0 > crypto->cryspr->km_unwrap(crypto->cryspr_cb, seks, - &km_msg[HCRYPT_MSG_KM_OFS_SALT + salt_len], - (unsigned int)((sek_cnt * sek_len) + HAICRYPT_WRAPKEY_SIGN_SZ))) { - HCRYPT_LOG(LOG_WARNING, "%s", "unwrap key failed\n"); + unsigned int msglen = (sek_cnt * sek_len) + HAICRYPT_WRAPKEY_SIGN_SZ; + int wrc = crypto->cryspr->km_unwrap(crypto->cryspr_cb, seks, + &km_msg[HCRYPT_MSG_KM_OFS_SALT + salt_len], msglen); + + if (wrc < 0) { + HCRYPT_LOG(LOG_WARNING, "%s%s\n", "unwrap key failed - internal KEK: ", rollback_kek ?
