* net: Add DEVTYPE support for Ethernet based devicesMarcel Holtmann2009-09-111-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Ethernet framing is used for a lot of devices these days. Most prominent are WiFi and WiMAX based devices. However for userspace application it is important to classify these devices correctly and not only see them as Ethernet devices. The daemons like HAL, DeviceKit or even NetworkManager with udev support tries to do the classification in userspace with a lot trickery and extra system calls. This is not good and actually reaches its limitations. Especially since the kernel does know the type of the Ethernet device it is pretty stupid. To solve this problem the underlying device type needs to be set and then the value will be exported as DEVTYPE via uevents and available within udev. # cat /sys/class/net/wlan0/uevent DEVTYPE=wlan INTERFACE=wlan0 IFINDEX=5 This is similar to subsystems like USB and SCSI that distinguish between hosts, devices, disks, partitions etc. The new SET_NETDEV_DEVTYPE() is a convenience helper to set the actual device type. All device types are free form, but for convenience the same strings as used with RFKILL are choosen. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: David S.

* Bluetooth: Fix rejected connection not disconnecting ACL linkLuiz Augusto von Dentz2009-08-221-0/+41
| | | | | | | | | | | | | | | | | | | | | | | | When using DEFER_SETUP on a RFCOMM socket, a SABM frame triggers authorization which when rejected send a DM response. This is fine according to the RFCOMM spec: the responding implementation may replace the "proper" response on the Multiplexer Control channel with a DM frame, sent on the referenced DLCI to indicate that the DLCI is not open, and that the responder would not grant a request to open it later either. But some stacks doesn't seems to cope with this leaving DLCI 0 open after receiving DM frame. To fix it properly a timer was introduced to rfcomm_session which is used to set a timeout when the last active DLC of a session is unlinked, this will give the remote stack some time to reply with a proper DISC frame on DLCI 0 avoiding both sides sending DISC to each other on stacks that follow the specification and taking care of those who don't by taking down DLCI 0.

* Bluetooth: Add support for Retransmission and Monitor TimersGustavo F. Padovan2009-08-221-4/+82
| | | | | | | | | | | L2CAP uses retransmission and monitor timers to inquiry the other side about unacked I-frames. After sending each I-frame we (re)start the retransmission timer. If it expires, we start a monitor timer that send a S-frame with P bit set and wait for S-frame with F bit set. If monitor timer expires, try again, at a maximum of L2CAP_DEFAULT_MAX_TX.

Now the packets are queued before call l2cap_do_send(), so packets couldn't be sent at the time we call l2cap_sock_sendmsg(). They will be sent in an asynchronous way on later calls of l2cap_ertm_send(). Besides if an error occurs on calling l2cap_do_send() we disconnect the channel.

* Bluetooth: Add extra device reference counting for connectionsMarcel Holtmann2009-08-222-1/+18
| | | | | | | | | | | | | | | | | | | | The device model itself has no real usable reference counting at the moment and this causes problems if parents are deleted before their children. The device model itself handles the memory details of this correctly, but the uevent order is not consistent. This causes various problems for systems like HAL or even X. So until device_put() does a proper cleanup, the device for Bluetooth connection will be protected with an extra reference counting to ensure the correct order of uevents when connections are terminated. This is not an automatic feature. Higher Bluetooth layers like HIDP or BNEP should grab this new reference to ensure that their uevents are send before the ones from the parent device.

| * bluetooth: rfcomm_init bug fixDave Young2009-08-032-9/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | rfcomm tty may be used before rfcomm_tty_driver initilized, The problem is that now socket layer init before tty layer, if userspace program do socket callback right here then oops will happen. reporting in: http://marc.info/?l=linux-bluetooth&m=124404919324542&w=2 make 3 changes: 1. remove #ifdef in rfcomm/core.c, make it blank function when rfcomm tty not selected in rfcomm.h 2. tune the rfcomm_init error patch to ensure tty driver initilized before rfcomm socket usage. 3. remove __exit for rfcomm_cleanup_sockets because above change need call it in a __init function.

| | | | | | | | | | | | | | | | String literals are constant, and usually, we can also tag the array of pointers const too, moving it to the .rodata section. Signed-off-by: Jan Engelhardt <jengelh@medozas.de> Signed-off-by: David S. Miller <davem@davemloft.net>
* | net: use NETDEV_TX_OK instead of 0 in ndo_start_xmit() functionsPatrick McHardy2009-07-051-3/+3
|/ | | | | | | | | | | This patch is the result of an automatic spatch transformation to convert all ndo_start_xmit() return values of 0 to NETDEV_TX_OK. Some occurences are missed by the automatic conversion, those will be handled in a seperate patch. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.
