From 5db90dbc941da701c397b04ddce2515a231df59b Mon Sep 17 00:00:00 2001 From: Alexandru Ardelean Date: Fri, 27 Jun 2014 19:11:42 +0300 Subject: [PATCH] libubus: fix writev_retry() function when writing large packets Seems this bug stayed hidden for a while, because the write/sendmsg function can send up to ~200k in one send, so it looked at first why there was some data mismatch. --- libubus-io.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/libubus-io.c b/libubus-io.c index f38403f..31dad27 100644 --- a/libubus-io.c +++ b/libubus-io.c @@ -111,7 +111,10 @@ static int writev_retry(int fd, struct iovec *iov, int iov_len, int sock_fd) if (!iov_len) return len; } + iov->iov_base += cur_len; iov->iov_len -= cur_len; + msghdr.msg_iov = iov; + msghdr.msg_iovlen = iov_len; } while (1); /* Should never reach here */ -- 2.30.2
