From 25579b4acd449e1bae30d2a20a44b77741c8e1fd Mon Sep 17 00:00:00 2001 From: Florin Coras Date: Wed, 6 Jun 2018 17:55:02 -0700 Subject: tcp: cleanup connection/session fixes - Cleanup session state after last ack and avoid using a cleanup timer. - Change session cleanup to free the session as opposed to waiting for delete notify. - When in close-wait, postpone sending the fin on close until all outstanding data has been sent. - Don't flush rx fifo unless in closed state Change-Id: Ic2a4f0d5568b65c83f4b55b6c469a7b24b947f39 Signed-off-by: Florin Coras --- src/svm/svm_fifo.c | 7 +++++++ src/svm/svm_fifo.h | 1 + 2 files changed, 8 insertions(+) (limited to 'src/svm') diff --git a/src/svm/svm_fifo.c b/src/svm/svm_fifo.c index 10c319236ee..47df22547ac 100644 --- a/src/svm/svm_fifo.c +++ b/src/svm/svm_fifo.c @@ -828,6 +828,13 @@ svm_fifo_dequeue_drop (svm_fifo_t * f, u32 max_bytes) return total_drop_bytes; } +void +svm_fifo_dequeue_drop_all (svm_fifo_t * f) +{ + f->head = f->tail; + __sync_fetch_and_sub (&f->cursize, f->cursize); +} + u32 svm_fifo_number_ooo_segments (svm_fifo_t * f) { diff --git a/src/svm/svm_fifo.h b/src/svm/svm_fifo.h index 39cdcc06a0c..90a49c03fc1 100644 --- a/src/svm/svm_fifo.h +++ b/src/svm/svm_fifo.h @@ -152,6 +152,7 @@ int svm_fifo_dequeue_nowait (svm_fifo_t * f, u32 max_bytes, u8 * copy_here); int svm_fifo_peek (svm_fifo_t * f, u32 offset, u32 max_bytes, u8 * copy_here); int svm_fifo_dequeue_drop (svm_fifo_t * f, u32 max_bytes); +void svm_fifo_dequeue_drop_all (svm_fifo_t * f); u32 svm_fifo_number_ooo_segments (svm_fifo_t * f); ooo_segment_t *svm_fifo_first_ooo_segment (svm_fifo_t * f); void svm_fifo_init_pointers (svm_fifo_t * f, u32 pointer); -- cgit 1.2.3-korg
