2012-05-17net: l2tp: Standardize logging stylesJoe Perches8-221/+213
Use more current logging styles. Add pr_fmt to prefix output appropriately. Convert printks to pr_<level>. Convert PRINTK macros to new l2tp_<level> macros. Neaten some <foo>_refcount debugging macros. Use print_hex_dump_bytes instead of hand-coded loops. Coalesce formats and align arguments. Some KERN_DEBUG output is not now emitted unless dynamic_debugging is enabled. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: James Chapman <jchapman@katalix.com> Signed-off-by: David S.

2012-05-16fq_codel: should use qdisc backlog as thresholdEric Dumazet2-4/+5
codel_should_drop() logic allows a packet being not dropped if queue size is under max packet size. In fq_codel, we have two possible backlogs : The qdisc global one, and the flow local one. The meaningful one for codel_should_drop() should be the global backlog, not the per flow one, so that thin flows can have a non zero drop/mark probability.

2012-05-16Bluetooth: Lock the L2CAP channel when sendingMat Martineau1-6/+6
The ERTM and streaming mode transmit queue must only be accessed while the L2CAP channel lock is held. Locking the channel before calling l2cap_chan_send ensures that multiple threads cannot simultaneously manipulate the queue when sending and receiving concurrently. L2CAP channel locking had previously moved to the l2cap_chan struct instead of the associated socket, so some of the old socket locking can also be removed in this patch.

2012-05-16Bluetooth: Restore locking semantics when looking up L2CAP channelsMat Martineau1-7/+3
As the comment for l2cap_get_chan_by_scid indicated, the function used to return a locked socket. The lock for the socket was acquired while the channel list was also locked. When locking was moved over to the l2cap_chan structure, the channel lock was no longer acquired with the channel list still locked. This made it possible for the l2cap_chan to be deleted after conn->chan_lock was released but before l2cap_chan_lock was called. Making the call to l2cap_chan_lock before releasing conn->chan_lock makes it impossible for the l2cap_chan to be deleted at the wrong time.

2012-05-16Bluetooth: Fix a redundant and problematic incoming MTU checkMat Martineau1-20/+0
The L2CAP MTU for incoming data is verified differently depending on the L2CAP mode, so the check is best performed in a mode-specific context. Checking the incoming MTU before HCI fragment reassembly is a layer violation and assumes all bytes after the standard L2CAP header are L2CAP data. This approach causes issues with unsegmented ERTM or streaming mode frames, where there are additional enhanced or extended headers before the data payload and possible FCS bytes after the data payload. A valid frame could be as many as 10 bytes larger than the MTU. Removing this code is the best fix, because the MTU is checked later on for all L2CAP data frames (connectionless, basic, ERTM, and streaming). This also gets rid of outdated locking (socket instead of l2cap_chan) and an extra lookup of the channel ID.

2012-05-16Bluetooth: Fix packet size provided to the controllerGustavo Padovan1-2/+6
When building fragmented skb's skb->len keeps track of the size of head plus all fragments combined, however when queueing the skb for sending we need to report the head size instead of the total size, so we just set skb->len to skb_headlen(). This bug appeared when implementing MSG_MORE support for L2CAP sockets, it never showed up before because l2cap_skbuff_fromiovec() never accounted skb size correctly. A following patch will fix this.
