* Add option in dlt.conf for bindAddress to specific IPs (#130)AdrianStoenescu2019-09-031-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | Add the possibility to have in dlt.conf an option that specifies a set of IP addresses. The daemon will do a socket bind only for this list, therefore external connections will be limited to this set of IP addresses. If this option is not given, the default INADDR_ANY is used ("0.0.0.0") as before. The option in dlt.conf can look like this: BindAddress = 160.48.199.98;160.48.199.97;160.48.199.226,160.48.199.186;160.48.199.139;172.16.222.99 There can be as many addresses but only specified on one single line. They have to be delimited by ',' or ';'. ' ' (space) delimiter does not work. IPv6 addresses are supported as well. For instance: BindAddress = fe80::255:7bff:feb5:7df7 IPv6 addresses are acceptable only if DLT_USE_IPv6 flag is ON at compile time. IPv4 addresses are acceptable only if DLT_USE_IPv6 flag is OFF at compile time. One cannot have both IPv4 and IPv6 format in the same time. Signed-off-by: Adrian Stoenescu Adrian.Stoenescu@harman.com

| | | | | | | | | | | | | | | 1. Allow building as a subproject of another cmake project (CMAKE_* vs PROJECT_* variables) 2. Do not generate header files within source – bad practice, use build directory for that(e.g. change location where dlt_version.h is being generated) 3. Use add_compile_options() instead of *_C/CXX_FLAGS variables for proper compile environment definition, also bad practice, also see p.2 4. Add WITH_DLT_PKGCONFIG – add generate pkgconfig .pc files as switchable option, should probably be part of headers install routine.

* daemon: Remove bytes_sentSaya Sugiura2019-06-181-1/+0
| | | | | | | | | | | | | | | | | | | | | When it fails to send a log message to connected client, daemon tries to store the remaining partial message to internal ring buffer and send again later. When calculating the number of bytes which were sent to client, it had a bug which it keeps on incrementing instead of initializing the variable on every message, which never reached to the condition mentioned above and had a possibility to overflow and access invalid memory. On the other hand, daemon doesn't need to store the unsent partial message, as the socket to the client will be closed on failure and the sent partial message will be dropped anyways. This commit removes the lines where the daemon tries to store the partial message to ring buffer. With this, variable bytes_sent is now removed.

* Update dlt_user.h (#22)Jens Lorenz2017-08-071-2/+2
| | | | | | | The dlt_user_log_write_start* function description mention the verbose/non-verbose option. According to my understanding verbose means that the code contains the verbose version of message (message as full string).

Therefore the comments should be modified to capture this correctly.

| | | | | | | | | | | | | | | | | | | | | | | | On context and application registration, the data needs to be read in 2 parts. If the first part was at the end of the receiver buffer, it was wrongly removed whereas the complete data is not full received and therefore interpretable. This has to be fixed by not removing the data before everything is checked. Thus, while readjusting the buffer to the first found header, the offset was not properly updated.

* Dlt MultiNodeChristoph Lipka2015-12-072-0/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MultiNode allows to connect DLT Daemons running on different operating systems, e.g. in a virtualized environment. The central component is the Gateway DLT Daemon which connects external DLT Clients, like the DLT Viewer running on a host computer, with Passive DLT Daemons running on nodes without a physical connection to external DLT clients. The Gateway DLT Daemon itself acts as a DLT client when connecting to a Passive DLT Daemon. To use the Gateway functionality, it has to be enabled in dlt.conf: GatewayMode = 1 All communication between passive nodes and DLT Viewer has to be send via the Gateway node. The Gateway node forwards log messages coming from passive nodes to all connected DLT clients. It also forwards command and control requests coming from DLT clients to the corresponding passive node. The Gateway DLT Daemon read a configuration file (dlt_gateway.conf) at startup with information about Passive DLT Daemon connections. Afterwards, the Daemon will try to connect to the passive DLT Daemons. If the connection cannot be established after the configured timeout, the Gateway DLT Daemon will give up connecting. The configuration file has to contain the following information about a passive node: [PassiveNode1] IPaddress = 192.168.2.35 Port = 3490 EcuID = ECU2 Connect = OnStartup ; timeout in seconds Timeout = 10 Precondition is, that the passive node is configured with the correct ECU id, ECU2 in this case. If the passive node sends messages with another than configured ECU id, the Gateway DLT Daemon will shut down the connection. It is also possible to connect to a passive DLT daemon using the dlt-passive-node-ctrl application. In this case "Connect=OnDemand" has to be configured in the configuration file. To connect to PassiveNode1, "dlt-passive-node-ctrl -n ECU2 -c 1" has to be executed. With "dlt-passive-node-ctrl -s" the status of passive node connections can be retrieved.

* Unix socket control interfaceChristoph Lipka2015-11-241-1/+10
| | | | | | | | | | | | | | | | Control applications running in the same Linux OS should be able to communicate with the DLT Daemon via a socket connection. To be able to do that, the DLT Client library need to be extended. DLT Clients connected via this UNIX socket are not handled as normal DLT Clients and no log messages will be forwarded to them. This avoids problems in situations when a control application is connected to the DLT Daemon before any other 'real' DLT Client (e.g. DLT Viewer) is connected. In this situations, all already stored log messages are flushed to the control application and therefore lost, because the control application most likely ignore all incoming messages besides the one in which it is interested in.
