2020-07-10Replace HTTP links with HTTPS ones: BLUETOOTH SUBSYSTEMAlexander A. Klimov
Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

2019-07-26bluetooth: switch to AES libraryArd Biesheuvel
The bluetooth code uses a bare AES cipher for the encryption operations. Given that it carries out a set_key() operation right before every encryption operation, this is clearly not a hot path, and so the use of the cipher interface (which provides the best implementation available on the system) is not really required. In fact, when using a cipher like AES-NI or AES-CE, both the set_key() and the encrypt() operations involve en/disabling preemption as well as stacking and unstacking the SIMD context, and this is most certainly not worth it for encrypting 16 bytes of data. So let's switch to the new lightweight library interface instead. Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2017-09-28Revert "Bluetooth: Add option for disabling legacy ioctl interfaces"Linus Torvalds
This reverts commit dbbccdc4ced015cdd4051299bd87fbe0254ad351. It turns out that the "legacy" users aren't so legacy at all, and that turning off the legacy ioctl will break the current Qt bluetooth stack for bluetooth LE devices that were released just a couple of months ago. So it's simply not true that this was a legacy interface that hasn't been needed and is only limited to old legacy BT devices. Because I actually read Kconfig help messages, and actively try to turn off features that I don't need, I turned the option off. Then I spent _way_ too much time debugging BLE issues until I realized that it wasn't the Qt and subsurface development that had broken one of my dive computer BLE downloads, but simply my broken kernel config. Maybe in a decade it will be true that this is a legacy interface. And maybe with a better help-text and correct dependencies, this kind of legacy removal might be acceptable. But as things are right now both the commit message and the Kconfig help text were misleading, and the Kconfig option had the wrong dependenencies. There's no reason to keep that broken Kconfig option in the tree.

2014-11-02Bluetooth: Introduce BT_BREDR and BT_LE config optionsMarcel Holtmann
The current kernel options do not make it clear which modules are for Bluetooth Classic (BR/EDR) and which are for Bluetooth Low Energy (LE).

2014-07-126lowpan: introduce new net/6lowpan directoryAlexander Aring
This patch moves generic code which is used by bluetooth and ieee802154 6lowpan to a new net/6lowpan directory. This directory contains generic 6LoWPAN code which is shared between bluetooth and ieee802154 MAC-Layer. This is the IPHC - "IPv6 Header Compression" format at the moment. Which is described by RFC 6282 [0]. The BLTE 6LoWPAN draft describes that the IPHC is the same format like IEEE 802.15.4, see [1]. Futuremore we can put more code into this directory which is shared between BLTE and IEEE 802.15.4 6LoWPAN like RFC 6775 or the routing protocol RPL RFC 6550. To avoid naming conflicts I renamed 6lowpan-y to ieee802154_6lowpan-y in net/ieee802154/Makefile.

2014-07-03Bluetooth: 6LoWPAN: Create a kernel moduleJukka Rissanen
Instead of adding the 6LoWPAN functionality to Bluetooth module, we create a separate kernel module for it. Usage: In the slave side do this: $ modprobe bluetooth_6lowpan $ echo 62 > /sys/kernel/debug/bluetooth/6lowpan_psm $ hciconfig hci0 leadv In the master side do this: $ modprobe bluetooth_6lowpan $ echo 62 > /sys/kernel/debug/bluetooth/6lowpan_psm $ echo 'connect E0:06:E6:B7:2A:73 1' > \ /sys/kernel/debug/bluetooth/6lowpan_control The 6LoWPAN functionality can be controlled by psm value. If it is left to 0, then the module is disabled and all the 6LoWPAN connections are dropped if there were any. In the above example, the psm value is just an example and not a real value for 6LoWPAN service. The real psm value is yet to be defined in Bluetooth specification. The 6lowpan controlling interface is a temporary solution until the specifications are ready.

2014-03-13Bluetooth: make sure 6LOWPAN_IPHC is built-in if neededArnd Bergmann
Commit 975508879 "Bluetooth: make bluetooth 6lowpan as an option" ensures that 6LOWPAN_IPHC is turned on when we have BT_6LOWPAN enabled in Kconfig, but it allows building the IPHC code as a loadable module even if the entire Bluetooth stack is built-in, and that causes a link error. We can solve that by moving the 'select' statement into CONFIG_BT, which is a "tristate" option to enforce that 6LOWPAN_IPHC can only be a module if BT also is a module.

2014-03-11Bluetooth: make bluetooth 6lowpan as an optionAlexander Aring
Currently you can have bluetooth 6lowpan without ipv6 enabled. This doesn't make any sense. With this patch you can disable/enable bluetooth 6lowpan support at compile time. The current bluetooth 6lowpan implementation doesn't check the return value of 6lowpan function. Nevertheless I added -EOPNOTSUPP as return value if 6lowpan bluetooth is disabled.

2014-01-15net: move 6lowpan compression code to separate moduleDmitry Eremin-Solenikov

2011-02-14Bluetooth: Merge L2CAP and SCO modules into bluetooth.koGustavo F. Padovan
Actually doesn't make sense have these modules built separately. The L2CAP layer is needed by almost all Bluetooth protocols and profiles. There isn't any real use case without having L2CAP loaded. SCO is only essential for Audio transfers, but it is so small that we can have it loaded always in bluetooth.ko without problems.

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!
