This patch converts all sizeof(x)/sizeof(x[0]) instances to ARRAY_SIZE macro in phytbl_lcn.c. The patch was made using spatch with ARRAY_SIZE.cocci (see [1]).

The function wlc_lcnphy_load_tx_gain_table() has a target PA gain specified for the iPA variant of the bcm4313. This gain value is reduced to avoid PA distortion. The if-statement is removed because it was rather redundant in the first place. Please note that this patch does not provide full iPA support.

Bug 60747 - 1286:2044 [Microsoft Surface Pro] Marvell 88W8797 wifi show 3 interface under network https://bugzilla.kernel.org/show_bug.cgi?id=60747 This issue was also reported previously by OLPC and some folks from the community. There are 3 network interfaces with different types being created when mwifiex driver is loaded: 1. mlan0 (infra. STA) 2. uap0 (AP) 3. p2p0 (P2P_CLIENT) The Network Manager attempts to use all 3 interfaces above without filtering the managed interface type. As the result, 3 identical interfaces are displayed under network manager. If user happens to click on an entry under which its interface is uap0 or p2p0, the association will fail. Work around it by removing the creation of AP and P2P interfaces at driver loading time. These interfaces can be added with 'iw' or other applications manually when they are needed.

The current code in the 'rt2800_adjust_freq_offset' function limits the device specific frequency offset value to FREQ_BOUND but ignores the fact that the uppermost bit is not part of the frequency offset value. As the result, the driver always uses the FREQ_BOUND value if the uppermost bit is set. Update the code to use the correct source value for calculating the boundary.

When initiating a transparent eSCO connection, make use of T2 settings at first try. T2 is the recommended settings from HFP 1.6 WideBand Speech. Upon connection failure, try T1 settings. When CVSD is requested and eSCO is supported, try to establish eSCO connection using S3 settings. If it fails, fallback in sequence to S2, S1, D1, D0 settings. To know which setting should be used, conn->attempt is used. It indicates the currently ongoing SCO connection attempt and can be used as the index for the fallback settings table. These setting and the fallback order are described in Bluetooth HFP 1.6 specification p. 101.

Synchronous Connection Complete event can return error "Connection Rejected due to Limited resources (0x10)". Handling this error is required for SCO connection fallback.

Older Bluetooth devices may not support Setup Synchronous Connection or SCO transparent data. This is indicated by the corresponding LMP feature bits. It is not possible to know if the adapter support these features before setting BT_VOICE option since the socket is not bound to an adapter. An adapter can also be added after the socket is created. The socket can be bound to an address before adapter is plugged in. Thus, on a such adapters, if user request BT_VOICE_TRANSPARENT, outgoing connections fail on connect() and returns -EOPNOTSUPP. Incoming connections do not fail. However, they should only be allowed depending on what was specified in Write_Voice_Settings command. EOPNOTSUPP is choosen because connect() system call is failing after selecting route but before any connection attempt.

The tty_port can be released in two cases: when we get a HUP in the functions rfcomm_tty_hangup() and rfcomm_dev_state_change(). Or when the user releases the device in rfcomm_release_dev(). In these cases we set the flag RFCOMM_TTY_RELEASED so that no other function can get a reference to the tty_port. The use of !test_and_set_bit(RFCOMM_TTY_RELEASED) ensures that the 'initial' tty_port reference is only dropped once. The rfcomm_dev_del function is removed becase it isn't used anymore.

When a socket is in deferred state there does actually exist an underlying connection even though the connection state is not yet BT_CONNECTED. In the deferred state it should therefore be allowed to get socket options that usually depend on a connection, such as SCO_OPTIONS and SCO_CONNINFO. This patch fixes the behavior of some user space code that behaves as follows without it: $ sudo tools/btiotest -i 00:1B:DC:xx:xx:xx -d -s accept=2 reject=-1 discon=-1 defer=1 sec=0 update_sec=0 prio=0 voice=0x0000 Listening for SCO connections bt_io_get(OPT_DEST): getsockopt(SCO_OPTIONS): Transport endpoint is not connected (107) Accepting connection Successfully connected to 60:D8:19:xx:xx:xx. handle=43, class=000000 The conditions that the patch updates the if-statements to is taken from similar code in l2cap_sock.c which correctly handles the deferred state.

The rt2800pci driver uses the same [RT]XWI size for all chipsets, however some chips requires different values. The size of the [RT]XWI structures is a constant value for a given chipset and it does not depend on the underlying interface. Add a helper function which returns the correct values for the actual chipset and use the new helper both in the rt2800usb and in the rt2800pci drivers. This ensures that both drivers are using the correct values. Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
