From 834e8ca576868c5ecd104bd5ebec9968c7f80a0b Mon Sep 17 00:00:00 2001 From: Igor Sysoev Date: Thu, 28 Feb 2019 18:04:11 +0300 Subject: Fixed timer and event race condition. When idle timeout occurs at the same time as a request comes in, the timer handler closes connection while the read event triggers request processing, and this eventually leads to segmentation fault. --- src/nxt_conn_write.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'src/nxt_conn_write.c') diff --git a/src/nxt_conn_write.c b/src/nxt_conn_write.c index 80d6f5cf..298d8f75 100644 --- a/src/nxt_conn_write.c +++ b/src/nxt_conn_write.c @@ -22,9 +22,10 @@ nxt_conn_io_write(nxt_task_t *task, void *obj, void *data) c = obj; - nxt_debug(task, "conn write fd:%d", c->socket.fd); + nxt_debug(task, "conn write fd:%d er:%d bl:%d", + c->socket.fd, c->socket.error, c->block_write); - if (c->socket.error != 0) { + if (c->socket.error != 0 || c->block_write) { goto error; } -- cgit
