NFC: potential integer overflow problem in check_crc()

2012-05-25T15:16:16Z

If "buf[0]" is 255 then "len" gets set to 0. The call to "crc_ccitt(0xffff, buf, len - 2);" casts the "len - 2" to a high positive number which is ugly. Signed-off-by: Dan Carpenter Signed-off-by: John W. Linville

NFC: HCI based pn544 driver

2012-05-15T21:30:30Z

This is an NFC driver for NXP pn544. Unlike pn544.c, this one is based on the NFC HCI and SHDLC kernel layers. Signed-off-by: Eric Lapuyade Signed-off-by: Samuel Ortiz Signed-off-by: John W. Linville

NFC: Remove unneeded pn533 dev NULL check

2012-05-15T21:28:01Z

container_of() works by subtracting the offset of the member. The math can't really return a zero here. Sometimes people check it when they actually meant to check something else but in this case we can just remove the check.

NFC: Cache the core NFC active target pointer instead of its index

2012-05-15T21:27:59Z

The NFC Core now caches the active nfc target pointer, thereby avoiding the need to lookup the target table for each invocation of a driver ops. Consequently, pn533, HCI and NCI now directly receive an nfc_target pointer instead of a target index. Cc: Ilan Elias Signed-off-by: Eric Lapuyade Signed-off-by: Samuel Ortiz Signed-off-by: John W.

NFC: pn533 Rx chaining support

2012-04-12T19:10:44Z

When buffers on the receiption path exceed 262 bytes, the pn533 uses a chaining mechanism where the initiator has to send NULL data frames to fetch the remaining frames. We do that from a workqueue context while holding the cmd lock. Once the MI bit is gone, we aggregate the queued received skbs. Signed-off-by: Samuel Ortiz Signed-off-by: John W. Linville

NFC: Convert pn533 from tasklet to workqueues

2012-04-12T19:10:43Z

There is no need for soft IRQ contexts, and workqueues are more flexible. Signed-off-by: Samuel Ortiz Signed-off-by: John W. Linville

NFC: Remove the rf mode parameter from the DEP link up routine

2012-03-06T20:16:23Z

When calling nfc_dep_link_up, we implicitely are in initiator mode. Which means we also can provide the general bytes as a function argument, as all drivers will eventually request them. Signed-off-by: Samuel Ortiz Signed-off-by: John W. Linville

NFC: Export NFCID when detecting a p2p target with pn533

NFC: Export Jewel/Topaz ID from pn533

2012-03-06T20:16:22Z

The jewel ID is the NFCID1 for Topaz NFC tags. Signed-off-by: Samuel Ortiz Signed-off-by: John W. Linville

NFC: Export sensf from pn533

2012-03-06T20:16:22Z

sensf is the detection response for Felica NFC tags. Signed-off-by: Samuel Ortiz Signed-off-by: John W. Linville
