nfc: netlink: Add capability to reply to vendor_cmd with data

2015-08-20T20:00:11+00:00

A proprietary vendor command may send back useful data to the user
application.

For example, the field level applied on the NFC router antenna.

Still based on net/wireless/nl80211.c implementation,
add nfc_vendor_cmd_alloc_reply_skb and nfc_vendor_cmd_reply in
order to send back over netlink data generated by a proprietary
command.

nfc: nci: hci: Add check on skb nci_hci_send_cmd parameter

2015-08-20T19:56:36+00:00

skb can be NULL and may lead to a NULL pointer error.

Add a check condition before setting HCI rx buffer.

NFC: nci: export nci_core_reset and nci_core_init

2015-08-20T19:23:11+00:00

Some drivers needs to have ability to reinit NCI core, for example
after updating firmware in setup() of post_setup() callback. This
patch makes nci_core_reset() and nci_core_init() functions public,
to make it possible.

NFC: nci: Add post_setup handler

2015-08-20T19:22:34+00:00

Some drivers require non-standard configuration after NCI_CORE_INIT
request, because they need to know ndev->manufact_specific_info or
ndev->manufact_id. This patch adds post_setup handler allowing to do
such custom configuration.

nfc: netlink: Warning fix

2015-08-17T08:45:19+00:00

When NFC_ATTR_VENDOR_DATA is not set, data_len is 0 and data is NULL.

Fixes the following warning:

net/nfc/netlink.c:1536:3: warning: 'data' may be used uninitialized
+in this function [-Wmaybe-uninitialized]
      return cmd->doit(dev, data, data_len);

nfc: netlink: Add check on NFC_ATTR_VENDOR_DATA

2015-08-16T23:36:17+00:00

NFC_ATTR_VENDOR_DATA is an optional vendor_cmd argument.
The current code was potentially using a non existing argument
leading to potential catastrophic results.

NFC: nci: remove current SLEEP mode management

2015-06-12T22:08:09+00:00

NCI deactivate management was modified to support all NCI
deactivation type. Problem is that all the API are not ready
yet for it.

Problem is that with current code, when neard asks to deactivate
the tag it sends a deactivate SLEEP but nobody will then send a
IDLE deactivate. This IDLE deactivate is mandatory since NFC
controller can only be unlocked by DH.

NFC: nci: add generic uart support

2015-06-11T21:37:37+00:00

Some NFC controller supports UART as host interface.
As with SPI, a lot of code can be shared between vendor
drivers. This patch add the generic support of UART and
provides some extension API for vendor specific needs.

This code is strongly inspired by the Bluetooth HCI ldisc
implementation. NCI UART vendor drivers will have to register
themselves to this layer via nci_uart_register.

Underlying tty will have to be configured from user land
thanks to an ioctl.
