From ce4adcc6e5320062e0d993eb75152d165aaabbe6 Mon Sep 17 00:00:00 2001 From: Andreas Eversberg Date: Mon, 27 Jul 2009 19:24:04 +0200 Subject: [PATCH] mISDN: Fix handling of receive buffer size in L1oIP The size of receive buffer pointer was used to get size of receive buffer instead of recvbuf_size itself, so only 4/8 bytes could be transfered. This is a regression to 2.6.30 introduced by commit 8c90e11e3543d7de612194a042a148caeaab5f1d ("mISDN: Use kernel_{send,recv}msg instead of open coding") Signed-off-by: Andreas Eversberg Signed-off-by: Karsten Keil Signed-off-by: Linus Torvalds --- drivers/isdn/mISDN/l1oip_core.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/isdn/mISDN/l1oip_core.c b/drivers/isdn/mISDN/l1oip_core.c index 990e6a7e667..c3b661a666c 100644 --- a/drivers/isdn/mISDN/l1oip_core.c +++ b/drivers/isdn/mISDN/l1oip_core.c @@ -731,10 +731,10 @@ l1oip_socket_thread(void *data) while (!signal_pending(current)) { struct kvec iov = { .iov_base = recvbuf, - .iov_len = sizeof(recvbuf), + .iov_len = recvbuf_size, }; recvlen = kernel_recvmsg(socket, &msg, &iov, 1, - sizeof(recvbuf), 0); + recvbuf_size, 0); if (recvlen > 0) { l1oip_socket_parse(hc, &sin_rx, recvbuf, recvlen); } else { -- 2.20.1
