* mesh: Allow to finish key refresh when no AppKeys are storedInga Stotland2020-02-071-2/+5
| | | | | | | | | This handles a case when a Key Refresh procedure is in place with no application keys stored in the keyring. When KR procedure is finalized, the check for the presence of AppKeys storage directory does not return failure if the directory does not exist. Also, remove duplicate include.
* tools/btproxy: Add support for ISO packetsLuiz Augusto von Dentz2020-02-031-2/+18
| | | | This enables proxing ISO packets.
* emulator: Add initial support for BT 5.2Luiz Augusto von Dentz2020-02-035-43/+258
| | | | This adds the initial command/event decoding for 5.2.
* monitor: Add decoding for L2CAP Enhanced Credit Based PDUsLuiz Augusto von Dentz2020-02-032-0/+183
| | | | | | Enhanced Credit Based Flow Control Mode is used for L2CAP connection-oriented channels on LE and BR/EDR with flow control using a credit-based scheme for L2CAP data.
* monitor: Add support for ISO packetsLuiz Augusto von Dentz2020-02-034-1/+58
| | | | This enables decoding of ISO packets.
* monitor: Add decoding of ISO related Link Layer PDUsLuiz Augusto von Dentz2020-02-032-0/+148
| | | | This adds the decoding of ISO related Link Layer PDUs
* monitor: Add support for decoding ISO related commandsLuiz Augusto von Dentz2020-02-032-0/+968
| | | | This adds parsing of ISO related commands.
* mesh: remove unused node_set_device_key()Jakub Witowski2020-01-312-6/+0
| | | | | This patch removes node_set_device_key() function, because it is unused.
* mesh: use static node_comp instead of the pointerJakub Witowski2020-01-311-32/+24
| | | | | There is no need to use the pointer to the node_comp data. This pach uses static node_comp instead.
* mesh: Re-arrange replay protection check and addBrian Gix2020-01-313-47/+45
| | | | | | | Re-arranged for efficiency. Replay Protection was set up as an atomic check-and-add operation. Now we check the message early so we can discard it without taking further action, and only add it to the RPL once fully verified that it was authorized and addressed to us.
* mesh: Add NVM storage of Replay ProtectionBrian Gix2020-01-304-7/+334
| | | | | | | | | Mesh specification requires that Replay Protection be preserved across node restarts. This adds that storage in <node_uuid>/rpl/<iv_index>/<src> Realtime access remains in an l_queue structure, and stored as messages are processed.
* mesh: Apply Replay Protection to all incoming packetsBrian Gix2020-01-301-9/+7
| | | | | | Replay Protection was only being applied against Application Keys, but messages with Device Keys are just as vulnerable, and need to be checked as well.
* mesh: Clean-up unneeded Sequence Number incrementsBrian Gix2020-01-301-8/+9
| | | | | | Scrub of Sequence Number handling of OB messages to account for in-node delivery of segmented messages, so that each discrete message has a unique sequence number for the RPL.
* mesh: Move Replay Protection to mesh/net.cBrian Gix2020-01-305-115/+99
| | | | | | | The specification calls for a flatter Replay Protection List that applies to all processed messages, regardless of which credentials were used to secure them. So storage and checking is now centralized in mesh/net.c
* mesh: Relocate tree deletion to util.c/hBrian Gix2020-01-303-19/+27

* monitor: Add missing HCI command error code decodingSzymon Janc2020-01-301-0/+1
| | | | Packet Too Long (0x45 ) status code was missing.
* mesh: Handle publickey exchange phase for initiatorPrathyusha N2020-01-251-95/+133
| | | | | | | | In Public Key OOB case, when provisioner receives public key via OOB, provisioner has to send it's public key to remote node and and then proceed for authentication. Handle invalid keys case.
* mesh: Fix provisioning agent method call failureShaunak Soman2020-01-231-0/+5
| | | | | | Provisioning agent interface methods PublicKey, PrivateKey and Cancel do not accept any parameters. So, while invoking them explicitly set the parameters to "".
* doc/mesh-api: Fix reference discrepancy for Import()Inga Stotland2020-01-221-2/+2
| | | | Remove mentioning of ImportLocalNode() method, use Import() instead.
* tools/mesh: Implement model group subscription commandsInga Stotland2020-01-221-19/+86
| | | | | | | | | | | This adds implementation for: Config Model Subscription Delete Config Model Subscription Delete All Config Model Subscription Overwrite and adds handling vendor model IDs for Config Model Subscription Add Config Model Subscription Get
* tools/mesh: Add support for Vendor Model App Get/ListInga Stotland2020-01-221-8/+29
| | | | | This adds implementation for sending Config Vendor App Get message and receiving Config Vendor App List response.
* tools/mesh: Add length checks for rxed messagesInga Stotland2020-01-221-19/+21
| | | | | | This adds missing validation of received responses. If the length of a received message does not pass the validation, it's not processed.
* tools/mesh: Refactor code for generating model IDInga Stotland2020-01-221-33/+28
| | | | | | Common code for populating message buffer with Model ID (either SIG or vendor defined) for misc commands is refactored into a single function.
* shared: shell: Only omit consecutive duplicate history lines.Marijn Suijten2020-01-211-1/+4
| | | | | | | | | | | | Change rl_handler to append duplicate history, as long as it isn't identical to the last line. It prevents consecutive duplicates while still having an accurate overview of the most recent commands used, mimicking most modern shells. This addresses my only major gripe with bluetoothctl: pressing UP does not retrieve the last typed command when it is a duplicate of something else written (much) earlier in the history. It is especially noticeable when needing the same command repeatedly.
* mesh: Offload loopback packets to l_idle_onshot()Brian Gix2020-01-171-13/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Any packet that may be handled internally by the daemon must be sent in it's own idle_oneshot context, to prevent multiple nodes from handling and responding in the same context, eventually corrupting memory. This addresses the following crash: Program terminated with signal SIGSEGV, Segmentation fault. 0 tcache_get (tc_idx=0) at malloc.c:2951 2951 tcache->entries[tc_idx] = e->next; (gdb) bt 0 tcache_get (tc_idx=0) at malloc.c:2951 1 __GI___libc_malloc (bytes=bytes@entry=16) at malloc.c:3058 2 0x0000564cff9bc1de in l_malloc (size=size@entry=16) at ell/util.c:62 3 0x0000564cff9bd46b in l_queue_push_tail (queue=0x564d000c9710, data=data@entry=0x564d000d0d60) at ell/queue.c:136 4 0x0000564cff9beabd in idle_add (callback=callback@entry=0x564cff9be4e0 <oneshot_callback>, user_data=user_data@entry=0x564d000d4700, flags=flags@entry=268435456, destroy=destroy@entry=0x564cff9be4c0 <idle_destroy>) at ell/main.c:292 5 0x0000564cff9be5f7 in l_idle_oneshot (callback=callback@entry=0x564cff998bc0 <tx_worker>, user_data=user_data@entry=0x564d000d83f0, destroy=destroy@entry=0x0) at ell/idle.c:144 6 0x0000564cff998326 in send_tx (io=<optimized out>, info=0x7ffd035503f4, data=<optimized out>, len=<optimized out>) at mesh/mesh-io-generic.c:637 7 0x0000564cff99675a in send_network_beacon (key=0x564d000cfee0) at mesh/net-keys.c:355 8 snb_timeout (timeout=0x564d000dd730, user_data=0x564d000cfee0) at mesh/net-keys.c:364 9 0x0000564cff9bdca2 in timeout_callback (fd=<optimized out>, events=<optimized out>, user_data=0x564d000dd730) at ell/timeout.c:81 10 timeout_callback (fd=<optimized out>, events=<optimized out>, user_data=0x564d000dd730) at ell/timeout.c:70 11 0x0000564cff9bedcd in l_main_iterate (timeout=<optimized out>) at ell/main.c:473 12 0x0000564cff9bee7c in l_main_run () at ell/main.c:520 13 l_main_run () at ell/main.c:502 14 0x0000564cff9bf08c in l_main_run_with_signal (callback=<optimized out>, user_data=0x0) at ell/main.c:642 15 0x0000564cff994b64 in main (argc=<optimized out>, argv=0x7ffd03550668) at mesh/main.c:268
* mesh: Fix opcode for OP_VEND_MODEL_APP_GETInga Stotland2020-01-171-1/+1
| | | | | This changes the value of OP_VEND_MODEL_APP_GET to 0x804D (it was incorrectly set to 0x804C)
* lib: Adding missing op_code string conversionAlain Michaud2020-01-171-0/+1
| | | | Adding the missing string conversion for MGMG_OP_SET_BLOCKED_KEYS.
* adapter: Load keys that should be blocked by the kernelAlain Michaud2020-01-161-6/+134
| | | | | | | | | | | | | | This change accomplishes 2 things: 1. Drop device security data from previously paired devices using blocked keys. 2. Send the list of known bad keys that should be blocked to the kernel if supported. In particular keys from the Google Titan Security key are being blocked. For additional background information, please see https://security.googleblog.com/2019/05/titan-keys-update.html
* shared/util: Adding a shared ARRAY_SIZE macroAlain Michaud2020-01-161-0/+2
| | | | | This will allow other implementations within src/ to use a single definition of the ARRAY_SIZE macro.
* lib: MGMT_OP_SET_BLOCKED_KEYS Api definitionsAlain Michaud2020-01-161-0/+15
| | | | Adding the required definitions for the MGMT_OP_SET_BLOCKED_KEYS Api.

* mesh: Rename --index to --io, support additional io types.Michał Lowas-Rzechonek2020-01-161-20/+69
| | | | | | | | | | This allows specifying io type and options when invoking the daemon. When no "-i" is passed, meshd still runs with MESH_IO_TYPE_GENERIC and tries to attach to the first available HCI interface. Options "-i <n>" and "-i hci<n>" are just shortcuts for "--io=generic:<n>" and "--io=generic:hci<n>", respectively.

* mesh: Correctly generate NetKey listInga Stotland2020-01-141-8/+28
| | | | | | When responding with NetKey List Status, packed NetKey indices into 3 octets per pair. If number of NetKeys is odd, append the last key index as a 2-octet value.
* tools/mesh: Remove node's appkeys when deleting a netkeyInga Stotland2020-01-141-8/+17
| | | | | | | | | When a netkey is deleted from a remote node, all the appkeys bound to this netkey are expected to be deleted as well. This fixes app_key queue manipulation to avoid issues caused by modifying the queue while iterating over it: instead of iteration over all the entries, find a first bound key, delete it, find next... and so on, until there are no bound keys left in the app_keys queue.
* tools/mesh: Fix check condition for model IDInga Stotland2020-01-141-2/+2
| | | | | Use the value of VENDOR_ID_MASK to set/check vendor model and SIG model IDs
* tools/mesh: add commands for AppKey Get and NetKey GetInga Stotland2020-01-141-9/+91
| | | | | This implements commands to send AppKey Get and NetKey Get messages and to process AppKey List and NetKey List reponses
* mesh: Fix exiting IV_UPD_STATE when receiving first SNBMichał Lowas-Rzechonek2020-01-141-4/+10
| | | | | | | | | First valid SNB received from the network should cause the node to switch into IV_UPD_NORMAL state. Otherwise, it will never try to enter IV Update procedure when sequence number approaches the IV_UPDATE_SEQ_TRIGGER, because that's only allowed in IV_UPD_NORMAL.
* mesh: Allow apps to receive DevKey messages from external nodesMichał Lowas-Rzechonek2020-01-141-2/+1
| | | | | | | | | | After introducing "remote" flag for DevKeyMessageReceived in c8cd5b04ccd865deeb90b70ea649c0b6cc0385e6, we can now allow applications to received DevKey messages from external addresses as well as from local ones. This enables applications to properly implement models using DevKey security, by accepting only requests with "remote" flag set to false.
* mesh: Fix wholesale deletion of appkeys bound to a netkeyInga Stotland2020-01-141-5/+21
| | | | | | | | | When a netkey is deleted all the appkeys bound to this key has to be deleted as well. This fixes app_key queue manipulation to avoid issues caused by modifying the queue while iterating over it: instead of iteration over all the entries, find a first bound key, delete it, find next... and so on, until there are no bound keys left in the app_keys queue.
* mesh: Fix logic in AppKey deletionInga Stotland2020-01-143-32/+7
| | | | | | | | When deleting an AppKey from a node, call mesh_config_app_key_del() only from appkey level (i.e., keep it contained in appkey.c and remove the duplicate call in node.c) Also, simplify the node_app_key_delete() argument list.
* avctp: Fix EINVAL on uinput creationHaochen Tong2020-01-131-0/+2
| | | | | | The struct uinput_dev variable is on stack, so clear its content to avoid accidentally writing garbage values to kernel. This fixes "Can't create uinput device: Invalid argument (22)" in some cases.
* mesh: Implement provisioning loop-backBrian Gix2020-01-131-33/+130
| | | | This allows one App using the mesh daemon to provision another.

In this situation, the recovering process goes into sink.c:sink_free and then a2dp.c:a2dp_cancel, avdtp.c:cancel_request, avdtp.c:connection_lost, avdtp.c:release_stream. During recovering, the reference count of setup and avdtp decrease more than it increase, which ends up causing the crash. The reference count of setup decreases one more time since a2dp.c:setconf_cfm(called by cfm->set_configuration in avdtp.c:cancel_request) was called in the 'error mode', which didn't reference the setup, but in a2dp.c:abort_cfm(called by cfm->abort in avdtp.c:release_stream), the reference count decreased by 1. In this case, abort_cfm shouldn't be called as we already know setconf_cfm didn't send any request. Setting avdtp_sep_state to AVDTP_STATE_ABORTING should avoid this issue. The reference count of avdtp decrease one more time since both sink.c:sink_free and sink.c:sink_set_state(called from avdtp.c:connection_lost -> avdtp.c:avdtp_set_state) unreference avdtp for the session. The changes in sink.c should avoid the issue.
