* libdlt: Do not allow DLT usage in forked child (#95)Simon Herkenhoff2019-02-041-36/+58
| | | | | | | | | | | | | DLT shall not be used in a forked child until a variant of exec() is called, because DLT is using non async-signal-safe functions. The forking process can continue to use libdlt's logging facilities, but any attempt to use libdlt from the forked child will be denied. The fork-handler test is updated to reflect this by trying to log from the forked child which will fail. The fork then calls exec and runs another application that can continue to use DLT.

* lib: socket: Flush all data before closing socketSaya Sugiura2018-12-212-3/+40
| | | | | | | | | | | | | | Sometimes socket will be closed even not all of the data is flushed to daemon. So before closing, following will be handled: 1. Use shutdown() to shut down further transmissions 2. Subsequent read() to resend_buffer Also socket fd is reset in child fork handler since the socket itself will not be duplicated in the child process.

* Update dlt_user.c (#66)kundatipradeep2018-08-241-0/+13
| | | | In dlt_user_log_send_log and dlt_forward_msg API's when writing the data to DLT PIPE is not successful in scenario which returns "DLT_RETURN_PIPE_ERROR"(Non availability of dlt pipe post termination of DLT DAEMON) it ideally starts stores the data in internal buffer, and close the dlt user handle, which is quiet appropriate. The scenario were dlt application fails in writing data to dlt pipe returns DLT_RETURN_PIPE_ERROR and case were application buffer is full, the return value DLT_RETURN_PIPE_ERROR is over written to "DLT_RETURN_BUFFER_FULL" were dlt user handle will not be reset to -1, it till holds the former data which causes undefined behavior of dlt application(One behavior would be which calls dlt_user_queue_resend and internally allocates memory for segmented data and tries to free it at dlt_user_trace_network_segmented_thread which is not intended behavior, instead return silently when FIFO is not available)

| | | | | | | | | A new return value DLT_RETURN_USER_BUFFER_FULL is introduced which is returned by all dlt_user_log_write_* and dlt_log_* functions when the data to be added to the user buffer exceeds its size (datasize > DLT_USER_BUF_MAX_SIZE) Signed-off-by: Lutz Helwing <lutz_helwing@mentor.com>
* Revert truncation of string or raw blockLutz Helwing2016-04-221-26/+16
| | | | | | | | | | | | | | | Commit d319ebf4d2d449d70befae0eebbdd82c19c5315f introduced new handling of the situation when writing data to the user buffer would exceed its size. This was achieved by truncating the data to fit. This solution had a problem: It could lead to a buffer overflow when the updated arg_size gets negative (actually undefined value because it is unsigned). As a quick fix the behaviour is reverted to the state before the aforementioned commit. Signed-off-by: Lutz Helwing <lutz_helwing@mentor.com>

* Unix socket control interfaceChristoph Lipka2015-11-241-7/+43
| | | | | | | | | | | | | | | | 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.
