* Bluetooth: Remove assignments in if-statementsValentin Ilie2014-03-051-11/+16
| | | | | | | | Remove assignment in if-statements to be consistent with the coding style. Signed-off-by: Valentin Ilie <valentin.ilie@gmail.com> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
* Bluetooth: Stop BCSP/H5 timer before cleaning upMichael Knudsen2014-03-041-1/+3
| | | | | | | | | | | When stopping BCSP/H5, stop the retransmission timer before proceeding to clean up packet queues. The previous code had a race condition where the timer could trigger after the packet lists and protocol structure had been removed which led to dereferencing NULL or use-after-free bugs.

* Bluetooth: Provide hdev parameter to hci_recv_frame() driver callbackMarcel Holtmann2013-10-111-3/+2
| | | | | | | | | | To avoid casting skb->dev into hdev, just let the drivers provide the hdev directly when calling hci_recv_frame() function. This patch also fixes up all drivers to provide the hdev. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>

| * module_param: make bool parameters really bool (drivers & misc)Rusty Russell2012-01-131-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | module_param(bool) used to counter-intuitively take an int. In fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy trick. It's time to remove the int/unsigned int option. For this version it'll simply give a warning, but it'll break next kernel version.

* | Bluetooth: hci-uart-bcsp: Use GFP_ATOMIC in open()David Herrmann2012-02-131-1/+1
|/ | | | | | | | | | The uart_proto open() callback is not called in atomic context so we can safely sleep here. The caller hci_uart_set_proto() in hci_ldisc.c is an ioctl-handler and therefore can sleep.

* Bluetooth: Fix false errors from bcsp_pkt_cull functionWending Weng2009-08-241-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | The error message "Removed only %u out of %u pkts" is printed when multiple to be acked packets are queued. if (i++ >= pkts_to_be_removed) break; This will break out of the loop and increase the counter i when i==pkts_to_be_removed and the loop ends up with i=pkts_to_be_removed+1. The following line if (i != pkts_to_be_removed) { BT_ERR("Removed only %u out of %u pkts", i, pkts_to_be_removed); } will then display the false message. The counter i must not increase on the same statement. Signed-off-by: Wending Weng <wweng@rheinmetall.ca> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
* Bluetooth: Enable per-module dynamic debug messagesMarcel Holtmann2008-11-301-5/+0
| | | | | | | | | | | With the introduction of CONFIG_DYNAMIC_PRINTK_DEBUG it is possible to allow debugging without having to recompile the kernel. This patch turns all BT_DBG() calls into pr_debug() to support dynamic debug messages. As a side effect all CONFIG_BT_*_DEBUG statements are now removed and some broken debug entries have been fixed.

* [Bluetooth] Switch from OGF+OCF to using only opcodesMarcel Holtmann2007-10-221-1/+2
| | | | | | | | | | | | The Bluetooth HCI commands are divided into logical OGF groups for easier identification of their purposes. While this still makes sense for the written specification, its makes the code only more complex and harder to read. So instead of using separate OGF and OCF values to identify the commands, use a common 16-bit opcode that combines both values. As a side effect this also reduces the complexity of OGF and OCF calculations during command header parsing. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
* [PATCH] remove many unneeded #includes of sched.hTim Schmielau2007-02-141-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+749
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
