NFC: fix device-allocation error return

2017-11-05T23:53:39+00:00

A recent change fixing NFC device allocation itself introduced an
error-handling bug by returning an error pointer in case device-id
allocation failed. This is clearly broken as the callers still expected
NULL to be returned on errors as detected by Dan's static checker.

Fix this up by returning NULL in the event that we've run out of memory
when allocating a new device id.

Note that the offending commit is marked for stable (3.8) so this fix
needs to be backported along with it.

NFC: fix broken device allocation

2017-06-18T21:57:58+00:00

Commit 7eda8b8e9677 ("NFC: Use IDR library to assing NFC devices IDs")
moved device-id allocation and struct-device initialisation from
nfc_allocate_device() to nfc_register_device().

This broke just about every nfc-device-registration error path, which
continue to call nfc_free_device() that tries to put the device
reference of the now uninitialised (but zeroed) struct device:

kobject: '(null)' (ce316420): is not initialized, yet kobject_put() is being called.

The late struct-device initialisation also meant that various work
queues whose names are derived from the nfc device name were also
misnamed:

  421 root         0 SW<  [(null)_nci_cmd_]
  422 root         0 SW<  [(null)_nci_rx_w]
  423 root         0 SW<  [(null)_nci_tx_w]

Move the id-allocation and struct-device initialisation back to
nfc_allocate_device() and fix up the single call site which did not use
nfc_free_device() in its error path.

add mode parameter to deactivate_target functions.
This way we can manage different target state.

NFC: Forward NFC_EVT_TRANSACTION to user space

2015-02-02T20:50:40+00:00

NFC_EVT_TRANSACTION is sent through netlink in order for a
specific application running on a secure element to notify
userspace of an event. Typically the secure element application
counterpart on the host could interpret that event and act
upon it.

Forwarded information contains:
- SE host generating the event
- Application IDentifier doing the operation
- Applications parameters
