From 70f879d2852dfc042ad0911a4a6e4a1714c0eb83 Mon Sep 17 00:00:00 2001 From: Florin Coras Date: Fri, 13 Mar 2020 17:54:42 +0000 Subject: session tcp udp: consolidate transport snd apis Type: improvement Use only one api to retrieve transport send parameters. Additionally, allow transports to request postponing and descheduling of events. With this, tcp now requests descheduling of sessions when the connections are stuck probing for zero snd_wnd Signed-off-by: Florin Coras Change-Id: I722c974f3e68fa15424c519a1fffacda43af050c --- src/vnet/tcp/tcp_input.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'src/vnet/tcp/tcp_input.c') diff --git a/src/vnet/tcp/tcp_input.c b/src/vnet/tcp/tcp_input.c index 0e8e68b1339..4f31d21c3c1 100755 --- a/src/vnet/tcp/tcp_input.c +++ b/src/vnet/tcp/tcp_input.c @@ -1312,7 +1312,9 @@ tcp_update_snd_wnd (tcp_connection_t * tc, u32 seq, u32 ack, u32 snd_wnd) } else { - tcp_persist_timer_reset (tc); + if (PREDICT_FALSE (tcp_timer_is_active (tc, TCP_TIMER_PERSIST))) + tcp_persist_timer_reset (tc); + if (PREDICT_FALSE (!tcp_in_recovery (tc) && tc->rto_boff > 0)) { tc->rto_boff = 0; -- cgit 1.2.3-korg
