Sometimes suspend thread queues a command and wait for it's response, meanwhile WLAN driver power cycles the card which leads to crash. This patch makes sure that suspend thread is woken up in remove path. Signed-off-by:

btmrvl_remove_card() calls kthread_stop() to stop the main thread, but kthread_should_stop() is checked when all the activities are done in the main thread before sleeping. We will have kthread_should_stop() check as soon as main thread is woken up. This fixes a crash issue caused due to an invalid memory access while unnecessarily processing interrupts after card removal. Signed-off-by:

Marcel Holtmann authored
There are some old Bluetooth modules from Silicon Wave and Broadcom which support Inquiry Result with RSSI, but do not advertise it. The core has quirks in the code to enable that inquiry mode. However as it stands right now, that code is not even executed since entering the function to determine which inquiry mode requires that the device has the feature bit for Inquiry Result with RSSI set in the first place. So this makes this dead code that hasn't work for a long time. In conclusion, just remove these extra quirks and simplify the setup of the inquiry mode to be inline and with that a lot easier to read and understand. Signed-off-by:

This patch handles the IEEE802154 Kconfig entry as menuconfig. Furthermore we move this entry out of "Network Options" and put it into "Networking" where the other networking subsystems are. This requires a menuconfig entry like all other networking subsystems. Signed-off-by:

This patch makes the ieee802154 socket handling as module. Currently this is part of ieee802154 module. It pointed out that ieee802154 module has also two module_init/module_exit functions. One inside of core.c and the other in af_ieee802154.c. This patch will also solve this issue by handle the af_802154 as separate module. Signed-off-by:

The Roper Class 1 Bluetooth Dongle is another device that claims to support Bluetooth 1.2 specification, but does not support the HCI command for reading the local supported commands. < HCI Command: Read Local Version Information (0x04|0x0001) plen 0 > HCI Event: Command Complete (0x0e) plen 12 Read Local Version Information (0x04|0x0001) ncmd 1 status 0x00 HCI Version: 1.2 (0x2) HCI Revision: 0x0 LMP Version: 1.2 (0x2) LMP Subversion: 0x757 Manufacturer: Silicon Wave (11) It clearly claims Bluetooth 1.2 support and in that regard has the same issue as the AVM BlueFritz!

When the Bluetooth controllers requires an unconfigured state (for example when the BD_ADDR is missing), then it is important to try to register the SMP channels when the controller transitions to the configured state. This also fixes an issue with the debugfs entires that are not present for controllers that start out as unconfigured. Signed-off-by:

The sc_only_mode debugfs entry is used to read the current state of the Secure Connections Only mode. Before Bluetooth 4.2 this mode was only for BR/EDR controllers and with that tight to the support Secure Simple Pairing. Since Secure Connections is now available for BR/EDR and LE this debugfs entry is no longer correctly place. Move it to the common section and enable it when either BR/EDR Secure Connections feature is supported or when the controller has LE support. Signed-off-by:

The force_lesc_support debugfs option never really worked. It has a race condition between creating the debugfs entry and registering the L2CAP fixed channel for BR/EDR SMP support. Also this has been replaced with a working force_bredr_smp debugfs switch that developers can use now. Signed-off-by:

Marcel Holtmann authored
Testing cross-transport pairing that starts on BR/EDR is only valid when using a controller with BR/EDR Secure Connections. Devices will indicate this by providing BR/EDR SMP fixed channel over L2CAP. To allow testing of this feature on Bluetooth 4.0 controller or controllers without the BR/EDR Secure Connections features, introduce a force_bredr_smp debugfs option that allows faking the required AES connection.

Not needed, only four cases: - kfree_skb (or one of its aliases). Don't need to zero, memory will be freed. - kfree_skb_partial and head was stolen: memory will be freed. - skb_morph: The skb header fields (including tc ones) will be copied over from the 'to-be-morphed' skb right after skb_release_head_state returns. - skb_segment: Same as before, all the skb header fields are copied over from the original skb right away.

There is no need to set the clock speed in read/write which will be performed unnecessarily for each mdio access. Init it during probe is enough. Also, the hardcoded clock value is not a proper way for all SoCs. Signed-off-by:

Alexander Duyck says: ==================== fib_trie: Reduce time spent in fib_table_lookup by 35 to 75% These patches are meant to address several performance issues I have seen in the fib_trie implementation, and fib_table_lookup specifically. With these changes in place I have seen a reduction of up to 35 to 75% for the total time spent in fib_table_lookup depending on the type of search being performed. On a VM running in my Corei7-4930K system with a trie of maximum depth of 7 this resulted in a reduction of over 370ns per packet in the total time to process packets received from an ixgbe interface and route them to a dummy interface. This represents a failed lookup in the local trie followed by a successful search in the main trie.
