2011-12-18Bluetooth: Use correct struct for user_confirm_neg_replyJohan Hedberg1-1/+1
This patch fixes user_confirm_neg_reply to use the appropriate struct for accessing the call parameters. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Acked-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>
2011-12-18Bluetooth: Add timer for automatically disabling the service cacheJohan Hedberg2-5/+38
We do not want the service cache to be enabled indefinitely after mgmt_read_info is called. To solve this a timer is added which will automatically disable the cache if mgmt_set_dev_class isn't called within 5 seconds of calling mgmt_read_info.

2011-12-18Bluetooth: Move EIR and CoD update functions to a better positionJohan Hedberg1-173/+173
Due to the upcoming addition of a service cache timer the functions to update the EIR and CoD need to be higher up in mgmt.c in order to avoid unnecessary forward-declarations. This patch simply moves code around without any other changes in order to make subsequent patches more readable.

2011-12-18Bluetooth: Remove mgmt_set_service_cacheJohan Hedberg2-51/+12
Instead of having an explicit service cache command we can make the mgmt API simpler by implicitly enabling the cache when mgmt_read_info is called for the first time and disabling it when mgmt_set_dev_class is called.

2011-12-18Bluetooth: Move mgmt_set_fast_connectable to the right locationJohan Hedberg1-6/+6
Fast connectable is logically after the connectable property so that's where it should show up in the code as well (it's also after connectable in the settings bitfield).

2011-12-18Bluetooth: Update mgmt_read_info and related mgmt messagesJohan Hedberg1-52/+94
This patch updates the mgmt_read_info and related messages to the latest management API which uses a bitfield of settings instead of individual boolean values.

2011-12-18Bluetooth: Use system workqueue to schedule power_onGustavo F. Padovan2-2/+2
hdev->workqueue should be only for rx/tx, so move this one out. Acked-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>
2011-12-18Bluetooth: Remove work_add and work_del from hci_sysfsGustavo F. Padovan1-44/+27
As we run in process context now we don't need worqueue to add e del from sysfs. Acked-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>
2011-12-18Bluetooth: Use new alloc_workqueue()Gustavo F. Padovan1-1/+2
Update hdev workqueue API usage to use the new interface, this new interface also allow us to mark this workqueue as WQ_HIGHPRI, so now rx and tx work gets higher priority when running. Acked-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>
2011-12-18Bluetooth: move power_off to system workqueueGustavo F. Padovan2-2/+2
hdev->workqueue will be only for for rx/tx/cmd processing, all other small works should go to the system workqueue for now. Acked-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>
2011-12-18Bluetooth: Change l2cap chan_list to use RCUGustavo F. Padovan1-61/+58
This list has much more reads than writes, so RCU makes senses here, also it avoid deadlock against the socket lock. Acked-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>
2011-12-18Bluetooth: invert locking order in connect pathGustavo F. Padovan2-60/+59
This move some checking code that was in l2cap_sock_connect() to l2cap_chan_connect(). Thus we can invert the lock calls, i.e., call lock_sock() before hci_dev_lock() to avoid a deadlock scenario.

2011-12-18Bluetooth: Don't disable tasklets to call hdev->notify()Gustavo F. Padovan2-16/+4
It's pointless, we aren't protecting anything since btusb_notify() schedules a work to run, then all it operation happens without protection. If protection is really needed here, we will fix it further. Acked-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>

2011-12-18Bluetooth: Use RCU to manipulate chan_listGustavo F. Padovan2-10/+16
Instead of using tasklet_disable() to prevent acess to the channel use, we can use RCU and improve the performance of our code. Acked-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>

2011-12-18Bluetooth: Don't use spin_lock socket lock anymoreGustavo F. Padovan1-46/+20
We now run everything in process context, so the mutex lock is the best option. But in some places we still need the bh_lock_sock() Acked-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>
2011-12-18Bluetooth: Move L2CAP timers to workqueueGustavo F. Padovan1-39/+31

2011-12-18Bluetooth: Use delayed_work for connection timeoutGustavo F. Padovan1-4/+5
Bluetooth rx task runs now in a workqueue, so it a good approach run any timer that share locking with process context code also in a workqueue. Acked-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>
2011-12-18Bluetooth: Replace spin_lock by mutex in hci_devGustavo F. Padovan8-97/+97
Now we run everything in HCI in process context, so it's a better idea use mutex instead spin_lock. The macro remains hci_dev_lock() (and I got rid of hci_dev_lock_bh()), of course. Acked-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>
2011-12-18Bluetooth: Process recv path in a workqueue instead of a taskletMarcel Holtmann1-9/+10
Run recv process in workqueue helps a lot with our processing as the recv path will also be in the process context, i.e., now all our tx and rx are in process context. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>

2011-12-18netfilter: ctnetlink: use expect instead of master tuple in get operationPablo Neira Ayuso1-1/+3
Use the expect tuple (if possible) instead of the master tuple for the get operation. If two or more expectations come from the same master, the returned expectation may not be the one that user-space is requesting. This is how it works for the expect deletion operation. Although I think that nobody has been seriously using this. We accept both possibilities, using the expect tuple if possible. I decided to do it like this to avoid breaking backward compatibility.

2011-12-18netfilter: nf_conntrack: use atomic64 for accounting countersEric Dumazet4-31/+31

2011-12-17sch_gred: prefer GFP_KERNEL allocationsEric Dumazet1-7/+11
In control path, its better to use GFP_KERNEL allocations where possible. Before taking qdisc spinlock, we preallocate memory just in case we'll need it in gred_change_vq() This is a followup to commit 3f1e6d3fd37b (sch_gred: should not use GFP_KERNEL while holding a spinlock) Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

2011-12-17net: fix sleeping while atomic problem in sock mem_cgroup.Glauber Costa1-14/+14
We can't scan the proto_list to initialize sock cgroups, as it holds a rwlock, and we also want to keep the code generic enough to avoid calling the initialization functions of protocols directly, Convert proto_list_lock into a mutex, so we can sleep and do the necessary allocations. This lock is seldom taken, so there shouldn't be any performance penalties associated with that Signed-off-by: Glauber Costa <glommer@parallels.com> CC: Hiroyouki Kamezawa <kamezawa.hiroyu@jp.fujitsu.com> CC: David S.

2011-12-16ethtool: Define and apply a default policy for RX flow hash indirectionBen Hutchings1-13/+20
All drivers that support modification of the RX flow hash indirection table initialise it in the same way: RX rings are assigned to table entries in rotation. Make that default policy explicit by having them call a ethtool_rxfh_indir_default() function. In the ethtool core, add support for a zero size value for ETHTOOL_SRXFHINDIR, which resets the table to this default.

Add a new ethtool operation (get_rxfh_indir_size) to get the indirectional table size. Use this to validate the user buffer size before calling get_rxfh_indir or set_rxfh_indir. Use get_rxnfc to get the number of RX rings, and validate the contents of the new indirection table before calling set_rxfh_indir. Remove this validation from drivers.

2011-12-16unix_diag: Pending connections IDs NLAPavel Emelyanov1-0/+39
When establishing a unix connection on stream sockets the server end receives an skb with socket in its receive queue. Report who is waiting for these ends to be accepted for listening sockets via NLA. There's a lokcing issue with this -- the unix sk state lock is required to access the peer, and it is taken under the listening sk's queue lock. Strictly speaking the queue lock should be taken inside the state lock, but since in this case these two sockets are different it shouldn't lead to deadlock.
