Thu, 27 Oct 2022 23:18:04 +0000

Bluetooth: Add CONFIG_BT_LE_L2CAP_ECREDThis adds CONFIG_BT_LE_L2CAP_ECRED which can be used to enable L2CAPEnhanced Credit Flow Control Mode by default, previously it was onlypossible to set it via module parameter (e.g. bluetooth.enable_ecred=1).Since L2CAP ECRED mode is required by the likes of EATT which isrecommended for LE Audio this enables it by default.Signed-off-by: Luiz Augusto von Dentz Tested-By: Tedd Ho-Jeong An List of files: /linux-6.15/net/bluetooth/Kconfig

28a220aa - bluetooth: switch to AES library

Tue, 02 Jul 2019 19:41:41 +0000

bluetooth: switch to AES libraryThe bluetooth code uses a bare AES cipher for the encryption operations.Given that it carries out a set_key() operation right before everyencryption operation, this is clearly not a hot path, and so the use ofthe cipher interface (which provides the best implementation availableon 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 asstacking and unstacking the SIMD context, and this is most certainlynot 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 List of files: /linux-6.15/net/bluetooth/Kconfig

e49aa15e - Revert "Bluetooth: Add option for disabling legacy ioctl interfaces"

Thu, 28 Sep 2017 20:20:32 +0000

Revert "Bluetooth: Add option for disabling legacy ioctl interfaces"This reverts commit dbbccdc4ced015cdd4051299bd87fbe0254ad351.It turns out that the "legacy" users aren't so legacy at all, and thatturning off the legacy ioctl will break the current Qt bluetooth stackfor 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'tbeen needed and is only limited to old legacy BT devices. Because Iactually read Kconfig help messages, and actively try to turn offfeatures that I don't need, I turned the option off.Then I spent _way_ too much time debugging BLE issues until I realizedthat it wasn't the Qt and subsurface development that had broken one ofmy dive computer BLE downloads, but simply my broken kernel config.Maybe in a decade it will be true that this is a legacy interface. Andmaybe with a better help-text and correct dependencies, this kind oflegacy removal might be acceptable. But as things are right now boththe commit message and the Kconfig help text were misleading, and theKconfig 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 List of files: /linux-6.15/net/bluetooth/Kconfig
