[PATCH] ir-core: Fix null dereferences in the protocols sysfs interface

2010-09-22 Thread Brian Rogers
For some cards, ir_dev-props and ir_dev-raw are both NULL. These cards are
using built-in IR decoding instead of raw, and can't easily be made to switch
protocols.

So upon reading /sys/class/rc/rc?/protocols on such a card, return 'builtin' as
the supported and enabled protocol. Return -EINVAL on any attempts to change
the protocol. And most important of all, don't crash.

Can you look at including ir-core: Fix null dereferences in the

Fix memory corruption during IR initialization for various tuner cards

2009-09-04 Thread Brian Rogers

Mauro,

The attached git-formatted patch fixes a regression I just found that 
was introduced in 2.6.31-rc1. I hope it can make it into the release.

Subject: [PATCH] Fix memory corruption during IR initialization for various tuner cards

In two different places the IR_i2c_init_data structure is used to store some
data for particular cards that will later override the settings that would
otherwise be used by the ir-kbd-i2c driver in ir_probe(). The way those
settings get there is problematic: init_data is on the stack, and a pointer to
it is stored to be used after the function that sets it up returns. Not good.

init_data might be overwritten by the time ir_probe() runs. ir_probe() will
then call ir_input_init(), which proceeds to fill out the dev-keybit bit
array with a 1 in the appropriate slot for every key on the tuner's remote.

But if the keymap pointer now points to random garbage, that will be used
instead to determine where to write each 1. And since IR_KEYTAB_TYPE is u32,
it can be write millions of bits past the end of dev-keybit. Essentially
this bug writes a 1 to up to 128 random bits in memory, stopping early (and
oopsing) if or when it hits an invalid page.

To fix this, I define a static IR_i2c_init_data struct for each card that
needs one rather than creating the data on the stack. This way, I can supply a
pointer that will remain valid. Also I don't have to allocate memory just to
store information that's already known at compile time and I don't have bother
freeing it, either.

This fixes a regression caused by commit 4d7a2d6721.

As far as I can see, the em28xx and saa7134 drivers have the exact same

I tested it here with an em28xx device and I got the trouble. I've committed a
patch fixing it with this driver, with a different strategy, using dynamic
memory. I did a similar patch for saa7134, although I can't test it ATM. Tests 
with
saa7134 devices with i2c keyboards are welcome.
  


Works fine with the MSI t...@nywhere Plus that prompted my version of the 
patch.


A couple comments. It looks like since the saa7134_dev is allocated with 
kzalloc, you shouldn't have to zero out dev-info and dev-init_data.


Secondly, you misspelled my name in your commit messages. :)

Are you going to send this in for 2.6.31, or is it likely to wait until 
2.6.31.1? I filed a bug to track the regression:

[PATCH 1/2] em28xx: ir-kbd-i2c init data needs a persistent object

2009-09-23 Thread Brian Rogers
commit d2ebd0f806fdb6104903365e355675934eec22b2 upstream.

Original commit message:

ir-kbd-i2c's ir_probe() function can be called much later (i.e. at
ir-kbd-i2c module load), than the lifetime of a struct IR_i2c_init_data
allocated off of the stack in cx18_i2c_new_ir() at registration time.
Make sure we pass a pointer to a persistent IR_i2c_init_data object at
i2c registration time.

Thanks to Brian Rogers, Dustin Mitchell, Andy Walls and Jean Delvare to
rise this question.

Before this patch, if ir-kbd-i2c were probed after em28xx, trash data
were used. After the patch, no matter what order, it is properly
reported as tested by me:

input: i2c IR (i2c IR (EM2840 Hauppaug as /class/input/input10
ir-kbd-i2c: i2c IR (i2c IR (EM2840 Hauppaug detected at i2c-4/4-0030/ir0

[PATCH 2/2] saa7134: ir-kbd-i2c init data needs a persistent object

2009-09-23 Thread Brian Rogers
commit 7aedd5ec87686c557d48584d69ad880c11a0984d upstream.

Tested on MSI t...@nywhere Plus.

Original commit message:

ir-kbd-i2c's ir_probe() function can be called much later (i.e. at
ir-kbd-i2c module load), than the lifetime of a struct IR_i2c_init_data
allocated off of the stack in cx18_i2c_new_ir() at registration time.
Make sure we pass a pointer to a persistent IR_i2c_init_data object at
i2c registration time.

Thanks to Brian Rogers, Dustin Mitchell, Andy Walls and Jean Delvare to
rise this question.

Before this patch, if ir-kbd-i2c were probed after SAA7134, trash data
were used.

Compile tested only, but the patch is identical to em28xx one. So, it
should work properly.
