Questions regarding NetLink APIs.

Questions regarding NetLink APIs.

[Alok]

Marcel, 

I had a few queries regarding the netlink APIs. I have been referring to
net/wireless/nl80211.c for reference.

1. Would the ioctls on raw sock(BTPROTO_HCI), be converted into netlink
commands?
eg HCIGETDEVLIST (NLBLUETOOTH_CMD_GET_DEVLIST),
HCIGETDEVINFO    (NLBLUETOOTH_CMD_GET_DEV_INFO),
HCIDEVUP         (NLBLUETOOTH_CMD_DEVUP) .. etc 


2. Would the netlink attributes consist of HCI Ioctl requests
structures ? or individual structure members?
eg:

[NLBLUETOOTH_ATTR_DEV_INFO] = {.len = sizeof(struct hci_dev_info)} 


3. Would it be a separate kernel module? 

Thanks, 
Alok.

No. We will have the parameters inside the structure as direct
attributes.

No. It will be within bluetooth.ko.

Marcel,

Attaching 2 patches for netlink support.

1. Adds net/bluetooth/netlink.c for netlink support with initialization
and exit functions.

2. Registers a generic netlink family "bluetooth".

Let me know if anything needs to be modified.

Thanks,
Alok.
