From 9518f179128b02c221ffdd692249836bb05a94de Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sun, 13 Dec 2009 08:41:12 -0300 Subject: V4L/DVB (13685): Correct code taking the size of a pointer sizeof(print_buf) is just the size of the pointer. Change it to the size used in the allocation of print_buf earlier in the same function. A simplified version of the semantic patch that finds this problem is as follows: (http://coccinelle.lip6.fr/) // @@ expression *x; expression f; type T; @@ *f(...,(T)x,...) // Cc: Janne Grunau Signed-off-by: Julia Lawall Signed-off-by: Mauro Carvalho Chehab --- drivers/media/video/hdpvr/hdpvr-core.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'drivers/media/video/hdpvr') diff --git a/drivers/media/video/hdpvr/hdpvr-core.c b/drivers/media/video/hdpvr/hdpvr-core.c index e280eb178fe..51f393d03a4 100644 --- a/drivers/media/video/hdpvr/hdpvr-core.c +++ b/drivers/media/video/hdpvr/hdpvr-core.c @@ -145,7 +145,7 @@ static int device_authorization(struct hdpvr_device *dev) #ifdef HDPVR_DEBUG else { hex_dump_to_buffer(dev->usbc_buf, 46, 16, 1, print_buf, - sizeof(print_buf), 0); + 5*buf_size+1, 0); v4l2_dbg(MSG_INFO, hdpvr_debug, &dev->v4l2_dev, "Status request returned, len %d: %s\n", ret, print_buf); @@ -168,13 +168,13 @@ static int device_authorization(struct hdpvr_device *dev) response = dev->usbc_buf+38; #ifdef HDPVR_DEBUG - hex_dump_to_buffer(response, 8, 16, 1, print_buf, sizeof(print_buf), 0); + hex_dump_to_buffer(response, 8, 16, 1, print_buf, 5*buf_size+1, 0); v4l2_dbg(MSG_INFO, hdpvr_debug, &dev->v4l2_dev, "challenge: %s\n", print_buf); #endif challenge(response); #ifdef HDPVR_DEBUG - hex_dump_to_buffer(response, 8, 16, 1, print_buf, sizeof(print_buf), 0); + hex_dump_to_buffer(response, 8, 16, 1, print_buf, 5*buf_size+1, 0); v4l2_dbg(MSG_INFO, hdpvr_debug, &dev->v4l2_dev, " response: %s\n", print_buf); #endif -- cgit v1.2.3
