media: rc: check for integer overflow

2018-02-13T18:32:09Z

commit 3e45067f94bbd61dec0619b1c32744eb0de480c8 upstream. The ioctl LIRC_SET_REC_TIMEOUT would set a timeout of 704ns if called with a timeout of 4294968us. Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab [bwh: Backported to 3.2: open-code U32_MAX] Signed-off-by: Ben Hutchings

media/rc: Send sync space information on the lirc device

2015-03-06T00:39:19Z

commit a8f29e89f2b54fbf2c52be341f149bc195b63a8b upstream. Userspace expects to see a long space before the first pulse is sent on the lirc device. Currently, if a long time has passed and a new packet is started, the lirc codec just returns and doesn't send anything. This makes lircd ignore many perfectly valid signals unless they are sent in quick sucession. When a reset event is delivered, we cannot know anything about the duration of the space. But it should be safe to assume it has been a long time and we just set the duration to maximum. Signed-off-by: Austin Lund Signed-off-by: Mauro Carvalho Chehab Signed-off-by: Ben Hutchings

drivers/media: Add module.h to all files using it implicitly

2011-10-31T23:31:51Z

A pending cleanup will mean that module.h won't be implicitly everywhere anymore. Make sure the modular drivers in clocksource are actually calling out for explicitly in advance. Signed-off-by: Paul Gortmaker

[media] rc/ir-lirc-codec: cleanup __user tags

2011-10-11T20:48:36Z

The code here treated user pointers correctly, but the __user tags weren't used correctly so it caused Sparse warnings: Signed-off-by: Dan Carpenter Signed-off-by: Mauro Carvalho Chehab

[media] rc-core: lirc use unsigned int

2011-07-27T20:52:59Z

Durations can never be negative, so it makes sense to consistently use unsigned int for LIRC transmission. Contrary to the initial impression, this shouldn't actually change the userspace API. Signed-off-by: David Härdeman Signed-off-by: Mauro Carvalho Chehab

[media] rc/ir-lirc-codec: add back debug spew

2011-01-31T14:19:42Z

Some occasionally useful debug spew disappeared as part of a feature update a while back, and I'm finding myself in need of it again to help diagnose some issues. Signed-off-by: Jarod Wilson Signed-off-by: Mauro Carvalho Chehab

[media] rc: ir-lirc-codec: fix potential integer overflow

2010-12-29T10:17:02Z

'n' may be bigger than MAX_INT*sizeof(int), if so checking of truncated (int)(n/sizeof(int)) for LIRCBUF_SIZE overflow and then using nontruncated 'count' doesn't make sense. Also n may be up to sizeof(int)-1 bytes bigger than expected, so check value of (n % sizeof(int)) too. Signed-off-by: Vasiliy Kulikov Acked-by: Jarod Wilson Signed-off-by: Mauro Carvalho Chehab

[media] rc: rename the remaining things to rc_core

2010-12-29T10:16:50Z

The Remote Controller subsystem is meant to be used not only by Infra Red but also for similar types of Remote Controllers. The core is not specific to Infra Red. As such, rename: - ir-core.h to rc-core.h - IR_CORE to RC_CORE - namespace inside rc-core.c/rc-core.h To be consistent with the other changes. No functional change on this patch.
