Bluetooth: Introduce debug feature when dynamic debug is disabled

2020-05-11T10:16:27Z

In case dynamic debug is disabled, this feature allows a vendor platform to provide debug statement printing. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: Add framework for Microsoft vendor extension

2020-04-05T11:53:05Z

Micrsoft defined a set for HCI vendor extensions. Check the following link for details: https://docs.microsoft.com/en-us/windows-hardware/drivers/bluetooth/microsoft-defined-bluetooth-hci-commands-and-events This provides the basic framework to enable the extension and read its supported features. Drivers still have to declare support for this extension before it can be utilized by the host stack. Signed-off-by: Miao-chen Chou Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: Move debugfs configuration above the selftests

2020-04-05T11:53:02Z

This is just a cosmetic clean to move the selftests configuration option to the bottom of the list of options. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

crypto: skcipher - rename the crypto_blkcipher module and kconfig option

2019-11-01T05:42:47Z

Now that the blkcipher algorithm type has been removed in favor of skcipher, rename the crypto_blkcipher kernel module to crypto_skcipher, and rename the config options accordingly: CONFIG_CRYPTO_BLKCIPHER => CONFIG_CRYPTO_SKCIPHER CONFIG_CRYPTO_BLKCIPHER2 => CONFIG_CRYPTO_SKCIPHER2 Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

bluetooth: switch to AES library

2019-07-26T04:58:12Z

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 Signed-off-by: Herbert Xu

treewide: Add SPDX license identifier - Makefile/Kconfig

2019-05-21T08:50:46Z

Revert "Bluetooth: Add option for disabling legacy ioctl interfaces"

2017-09-28T20:20:32Z

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. Cc: Marcel Holtmann Cc: Johan Hedberg Signed-off-by: Linus Torvalds

Bluetooth: Add option for disabling legacy ioctl interfaces

2017-08-30T19:00:19Z

The legacy ioctl interfaces are only useful for BR/EDR operation and since Linux 3.4 no longer needed anyway. This options allows disabling them alltogether and use only management interfaces for setup and control. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: document config options

2017-08-08T14:02:13Z

Kernel config options should include useful help text; I had to look up the terms on wikipedia. Signed-off-by: Pavel Machek Signed-off-by: Marcel Holtmann

Bluetooth: convert smp and selftest to crypto kpp API

2017-04-25T02:53:42Z

* Convert both smp and selftest to crypto kpp API * Remove module ecc as no more required * Add ecdh_helper functions for wrapping kpp async calls This patch has been tested *only* with selftest, which is called on module loading. Signed-off-by: Salvatore Benedetto Signed-off-by: Marcel Holtmann
