* Bluetooth: Fix H4 crash from incoming UART packetsChan-yeol Park2013-04-041-0/+3
| | | | | | | | | | | | | | | | | | | | | | | This patch adds a check HCI_UART_REGISTERED before reading UART data in the HCI UART H4 driver. UART data could arrive when inside the hci_uart_tty_ioctl function after calling test_and_set_bit for HCI_UART_PROTO_SET but before the hci_uart_set_proto function has returned. Backtrace: [<c05f27ec>] (hci_recv_stream_fragment+0x0/0x74) from [<c04126f4>] (h4_recv+0x18/0x40) r7:eb1d4d1c r6:eb7683b0 r5:eae8e800 r4:0000000c [<c04126dc>] (h4_recv+0x0/0x40) from [<c0411870>] (hci_uart_tty_receive+0x6c/0x94) r5:eae8e800 r4:eb768380 [<c0411804>] (hci_uart_tty_receive+0x0/0x94) from [<c027be88>] (flush_to_ldisc+0x16c/0x17c) r6:eae8e8d8 r5:eae8e800 r4:eae8e8c8 [<c027bd1c>] (flush_to_ldisc+0x0/0x17c) from [<c0050ae8>] (process_one_work+0x144/0x4d4) [<c00509a4>] (process_one_work+0x0/0x4d4) from [<c0051208>] (worker_thread+0x180/0x370) [<c0051088>] (worker_thread+0x0/0x370) from [<c005617c>] (kthread+0x90/0x9c) [<c00560ec>] (kthread+0x0/0x9c) from [<c003a3a0>] (do_exit+0x0/0x7ec) Signed-off-by: Chan-yeol Park <chanyeol.park@samsung.com> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>

* Bluetooth: hci-uart-h4: 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: 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.

* [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-rc2Linus Torvalds2005-04-161-0/+282
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!
