From 93992a9048cb6e5dcd22de5091e72de778122627 Mon Sep 17 00:00:00 2001 From: Florin Coras Date: Wed, 24 May 2017 18:03:56 -0700 Subject: Implement sack based tcp loss recovery (RFC 6675) - refactor existing congestion control code (RFC 6582/5681). Handling of ack feedback now consists of: ack parsing, cc event detection, event handling, congestion control update - extend sack scoreboard to support sack based retransmissions - basic implementation of Eifel detection algorithm (RFC 3522) for detecting spurious retransmissions - actually initialize the per-thread frame freelist hash tables - increase worker stack size to 2mb - fix session queue node out-of-buffer handling - ensure that the local buffer cache vec_len matches reality - avoid 2x spurious event requeues when short of buffers - count out-of-buffer events - make the builtin server thread-safe - fix bihash template threading issue: need to paint -1 across uninitialized working_copy_length vector elements (via rebase from master) Change-Id: I646cb9f1add9a67d08f4a87badbcb117980ebfc4 Signed-off-by: Florin Coras Signed-off-by: Dave Barach --- src/vlib/threads.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/vlib/threads.c') diff --git a/src/vlib/threads.c b/src/vlib/threads.c index b7bc9e26..0c775e2d 100644 --- a/src/vlib/threads.c +++ b/src/vlib/threads.c @@ -670,7 +670,7 @@ start_workers (vlib_main_t * vm) /* zap the (per worker) frame freelists, etc */ nm_clone->frame_sizes = 0; - nm_clone->frame_size_hash = 0; + nm_clone->frame_size_hash = hash_create (0, sizeof (uword)); /* Packet trace buffers are guaranteed to be empty, nothing to do here */ -- cgit 1.2.3-korg
