2021-02-03Bluetooth: Fix crash in mgmt_add_adv_patterns_monitor_completeHoward Chung
If hci_add_adv_monitor is a pending command(e.g. forward to msft_add_monitor_pattern), it is possible that mgmt_add_adv_patterns_monitor_complete gets called before cmd->user_data gets set, which will cause a crash when we try to get the moniter handle through cmd->user_data in mgmt_add_adv_patterns_monitor_complete. This moves the cmd->user_data assignment earlier than hci_add_adv_monitor.

2020-12-07Bluetooth: Change MGMT security info CMD to be more genericDaniel Winkler
For advertising, we wish to know the LE tx power capabilities of the controller in userspace, so this patch edits the Security Info MGMT command to be more generic, such that other various controller capabilities can be included in the EIR data. This change also includes the LE min and max tx power into this newly-named command. The change was tested by manually verifying that the MGMT command returns the tx power range as expected in userspace.

2020-12-07Bluetooth: Use intervals and tx power from mgmt cmdsDaniel Winkler
This patch takes the min/max intervals and tx power optionally provided in mgmt interface, stores them in the advertisement struct, and uses them when configuring the hci requests. While tx power is not used if extended advertising is unavailable, software rotation will use the min and max advertising intervals specified by the client. This change is validated manually by ensuring the min/max intervals are propagated to the controller on both hatch (extended advertising) and kukui (no extended advertising) chromebooks, and that tx power is propagated correctly on hatch. These tests are performed with multiple advertisements simultaneously.

2020-12-07Bluetooth: Break add adv into two mgmt commandsDaniel Winkler
This patch adds support for the new advertising add interface, with the first command setting advertising parameters and the second to set advertising data. The set parameters command allows the caller to leave some fields "unset", with a params bitfield defining which params were purposefully set. Unset parameters will be given defaults when calling hci_add_adv_instance. The data passed to the param mgmt command is allowed to be flexible, so in the future if bluetoothd passes a larger structure with new params, the mgmt command will ignore the unknown members at the end. This change has been validated on both hatch (extended advertising) and kukui (no extended advertising) chromebooks running bluetoothd that support this new interface. I ran the following manual tests: - Set several (3) advertisements using modified test_advertisement.py - For each, validate correct data and parameters in btmon trace - Verified both for software rotation and extended adv Automatic test suite also run, testing many (25) scenarios of single and multi-advertising for data/parameter correctness.

2020-09-11Bluetooth: Add MGMT capability flags for tx power and ext advertisingDaniel Winkler
For new advertising features, it will be important for userspace to know the capabilities of the controller and kernel. If the controller and kernel support extended advertising, we include flags indicating hardware offloading support and support for setting tx power of adv instances. In the future, vendor-specific commands may allow the setting of tx power in advertising instances, but for now this feature is only marked available if extended advertising is supported.

2020-07-15Bluetooth: Add per-instance adv disable/removeDaniel Winkler
Add functionality to disable and remove advertising instances, and use that functionality in MGMT add/remove advertising calls. Currently, advertising is globally-disabled, i.e. all instances are disabled together, even if hardware offloading is available. This patch adds functionality to disable and remove individual adv instances, solving two issues: 1. On new advertisement registration, a global disable was done, and then only the new instance was enabled. This meant only the newest instance was actually enabled. 2. On advertisement removal, the structure was removed, but the instance was never disabled or removed, which is incorrect with hardware offload support.

2020-03-08Bluetooth: Enable erroneous data reporting if WBS is supportedAlain Michaud
This change introduces a wide band speech setting which allows higher level clients to query the local controller support for wide band speech as well as set the setting state when the radio is powered off. Internally, this setting controls if erroneous data reporting is enabled on the controller. Signed-off-by: Alain Michaud <alainm@chromium.org> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

2020-01-15Bluetooth: Implementation of MGMT_OP_SET_BLOCKED_KEYS.Alain Michaud
MGMT command is added to receive the list of blocked keys from user-space. The list is used to: 1) Block keys from being distributed by the device during the ke distribution phase of SMP. 2) Filter out any keys that were previously saved so they are no longer used.

2019-09-05Bluetooth: mgmt: Use struct_size() helperGustavo A. R. Silva
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct mgmt_rp_get_connections { ... struct mgmt_addr_info addr[0]; } __packed; Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes. So, replace the following form: sizeof(*rp) + (i * sizeof(struct mgmt_addr_info)); with: struct_size(rp, addr, i) Also, notice that, in this case, variable rp_len is not necessary, hence it is removed. This code was detected with the help of Coccinelle. Signed-off-by: Gustavo A. R. Silva <gustavo@embeddedor.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
