* BTAdapter::pausing_discovery_devices: Use std::weak_ptr<BTDevice> list; Add ↵Sven Gothel2021-11-292-6/+15
| | | | | | | | | | | | | | | | BTAdapter::removeDevicePausingDiscovery() and getCurrentDiscoveryPolicy() Using a weak_ptr<BTDevice> list avoid stopping BTDevice destruction. BTAdapter::removeDevicePausingDiscovery() allows manual DiscoveryPolicy intervention point, allowing user to remove the ready device from the queue of pausing-discovery devices. Manual intervention might be desired, if using DiscoveryPolicy::PAUSE_CONNECTED_UNTIL_DISCONNECTED, but allowing discovery at an earlier processing step from AdapterStatusListener::deviceReady(). +++ Further added removeDevicePausingDiscovery() call in BTAdapter::removeDevice() as a last resort.
* DiscoveryPolicy: Implement Discovery Policy, covering HCI host OS's implied ↵Sven Gothel2021-11-287-120/+53
| | | | | | | | | | | | | | | | | | | | | | discovery-off and detailed 'keep alive' options API change (earmark version 2.5.0): - AdapterStatusListener::discoveringChanged() - BTAdapter::startDiscovery() BTAdapter::startDiscovery() takes DiscoveryPolicy instead of bool keep_alive, allowing fine tuned discovery keep-alive policy and covering HCI host OS's implied discovery turn-off when connected (BlueZ/Linux). dbt_scanner10.cpp and DBTScanner10.java covery the new DiscoveryPolicy and user may pass its integer value via '-discoveryPolicy <0-4>'. These example were further adjusted as follows: - Removed WHITELIST variation of connection w/o discovery, cleaning up and simplifying example code - Remove manual start- and stopDiscovery() handling, ending up in a single startDiscovery() call @ init (and power-on).
* SMPKeyBin::createAndWrite(..): Drop 'overwrite' argument as we shall set ↵Sven Gothel2021-11-193-3/+3
| | | | | | | | overwrite = PairingMode::PRE_PAIRED != device.getPairingMode() Only PRE_PAIRED keys shall not be overwrite the existing file, as they don't need to be and hence can preserve their timestamp. However, another PairingMode indicates a new key and shall overwrite an existing file.

| | | | | | | | | | JavaUplink Use mutable and const field accessors, similar to upcoming Java 'proxy' classes. This shall help defining mutable and const reference data access. Revert adding JavaUplink to DBGatt[Desc|Char|Service] of commit 414c81b7214d895aba694ff444feca9cdc491bc5, as we do not link from native instance to Java.

Adds DBGattServer arg - Implementation is not yet functional, i.e. types are not yet mapped to native instance. - DBGattChar and DBGattDesc value currently just a 'byte[]' and lacks capacity: - Its capacity defines the maximum writable variable length - and its size defines the maximum writable fixed length.

* Add BTAdapter's Slave Peripheral SMP Key ManagementSven Gothel2021-10-292-24/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To have full SMP key persitency in peripheral slave mode, BTAdapter requires fine grained control over - Passing stored keys to BTDevice's PairingData (w/o uploading them) - Uploading BTDevice's PairingData to the adapter This required interaction in certain places, only enabled if adapter is BTRole::Slave (peripheral): - BTAdapter::mgmtEvDeviceConnectedHCI() Only issue unpairDevice() if not pre-paired. Unpairing is required for new pairing to avoid DHKey Check failures! - BTAdapter::mgmtEvDeviceDisconnectedHCI() - First unpairDevice() will be issued via notifyDisconnect() - Set and upload stored keys for disconnected device (if existing), preparing for next connect. - BTAdapter::sendDevicePairingState() - SMPPairingState::COMPLETED && not SMPPairingState::PRE_PAIRED: Store keys - SMPPairingState::COMPLETED && SMPPairingState::PRE_PAIRED: Refresh keys to BTDevice (set), no upload! - SMPPairingState::FAILED: Remove and delete keys +++ BTAdapter::setSMPKeyPath(path) allows user to enable the persistent key storage by setting its local filesystem path. It will also read all key files (SMPKeyBin) and if valid and matching with the adapter, uploads them for pre-pairing. See dbt_peripheral00.cpp: adapter->setSMPKeyPath(ADAPTER_KEY_PATH); +++
* Move SMPKeyBin 'apply' to BTDevice, splitting functionality: setting + ↵Sven Gothel2021-10-293-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | uploading keys (required for peripheral BTAdapter key management) SMPKeyBin has the key apply action revoked. SMPKeyBin is reduced to store keys, address and security settings, as well adding persistence (read/write to filesystem). BTDevice::setSMPKeyBin(SMPKeyBin&) shall be used copy the key data over and BTDevice::uploadKeys() to upload them to the adapter for pre-pairing. See dbt_scanner10.cpp's use of convenient API (same efficiency as before) device->uploadKeys(KEY_PATH, req_sec_level, true /* verbose_ */); BTDevice::setSMPKeyBin(SMPKeyBin&) fully restored BTDevice's PairingData - keys - key caps - user security level and IOCaps +++ The reduced 'set<Name>Key(..)' methods only - copy the key to BTDevice's PairingData - set the KeyType bit for keys_<role>_[init|resp], fully restoring key caps
* Issue BTDevice::unpair() directly when device is discovered, disconnected ↵Sven Gothel2021-10-284-35/+1
| | | | | | | | | | | | | | | | | | | | | | | | and connected as peripheral This enforces a consistent and stable security workflow. - when a BTRole::Slave BTDevice is discovered, see AdapterStatusListener::deviceFound(). - when a BTRole::Slave BTDevice is disconnected, see AdapterStatusListener::deviceDisconnected(). - when a BTRole::Master BTDevice gets connected, see AdapterStatusListener::deviceConnected(). +++ Especially when connected as peripheral without unpair in SC mode, the peripheral fails the DHKey Check. TODO: Provide a persistent pre-pairing mechanism via SMPKeyBin for peripheral mode. +++ Note: Our existing example code to connect to a remote slave/peripheral, already performed the unpair on deviceFound(..) and deviceDisconnected(). These calls have now being removed, as they are performed directly by Direct-BT. The example code uploads pre-existing keys for pre-pairing when device is found, if existing.
