From c3dd3dc55860a95b4c6f4b0ea7883f343d2d6d6c Mon Sep 17 00:00:00 2001 From: Richard Fuchs Date: Wed, 4 Sep 2024 10:39:01 -0400 Subject: [PATCH] MT#55283 trigger rekernel for SSRC-less streams If a stream has been pushed to the kernel from anything other than RTP, even though RTP is expected, we get a forwarding entries without any SSRCs. This is valid, but once actual RTP is received, it needs to be passed on to user space, so that SSRC contexts can be set up. Possible fix for #1855 Change-Id: I51b82d3cf79cf66780fdde154bebe56e0f43174b (cherry picked from commit a0b705eef9bc92c413074224b833584d60e7d93c) --- daemon/media_socket.c | 1 + kernel-module/xt_RTPENGINE.c | 2 +- kernel-module/xt_RTPENGINE.h | 1 + 3 files changed, 3 insertions(+), 1 deletion(-) diff --git a/daemon/media_socket.c b/daemon/media_socket.c index 9191d16c1..d62e79a71 100644 --- a/daemon/media_socket.c +++ b/daemon/media_socket.c @@ -1513,6 +1513,7 @@ static const char *kernelize_one(struct rtpengine_target_info *reti, GQueue *out if (proto_is_rtp(media->protocol)) { reti->rtp = 1; + reti->ssrc_req = 1; if (!MEDIA_ISSET(media, TRANSCODING)) { reti->rtcp_fw = 1; if (media->protocol->avpf) diff --git a/kernel-module/xt_RTPENGINE.c b/kernel-module/xt_RTPENGINE.c index a2cda6a9c..4b8537720 100644 --- a/kernel-module/xt_RTPENGINE.c +++ b/kernel-module/xt_RTPENGINE.c @@ -6374,7 +6374,7 @@ static unsigned int rtpengine46(struct sk_buff *skb, struct sk_buff *oskb, // Look for matching SSRC index if any SSRC were given ssrc_idx = target_find_ssrc(g, rtp.rtp_header->ssrc); errstr = "SSRC mismatch"; - if (ssrc_idx == -2) + if (ssrc_idx == -2 || (ssrc_idx == -1 && g->target.ssrc_req)) goto out_error; pkt_idx = rtp_packet_index(&g->decrypt_rtp, &g->target.decrypt, rtp.rtp_header, ssrc_idx, diff --git a/kernel-module/xt_RTPENGINE.h b/kernel-module/xt_RTPENGINE.h index d5c9e45df..d16996111 100644 --- a/kernel-module/xt_RTPENGINE.h +++ b/kernel-module/xt_RTPENGINE.h @@ -102,6 +102,7 @@ struct rtpengine_target_info { dtls:1, stun:1, rtp:1, + ssrc_req:1, rtp_only:1, track_ssrc:1, rtcp:1,
