2018-08-23Normalize syslog message line endingsDavid Oberhollenzer
Most syslog messages have a line feed at the end, but some don't. This patch removes trailing spaces from all syslog messages that have one and always adds a line feed in the logging back end. Signed-off-by: David Oberhollenzer <david.oberhollenzer@tele2.at>

2018-08-20usyslogd: merge log files for the same serviceDavid Oberhollenzer
If a service provides an identifier string, write all messages for that service itno a file named after that identifier instread of splitting it up by facility ID in a sub directory. This is supposed to cleanup and simplify the clutter created in /var/log. Signed-off-by: David Oberhollenzer <david.oberhollenzer@tele2.at>

2018-08-16usyslogd: create abstraction for log stream managementDavid Oberhollenzer
This commit seperates the formating and printing of log messages to files more cleanly from the message pump that retrieves the log messages. At a later point, other backends could be added more easiyl (e.g. forward the log message to some server). Signed-off-by: David Oberhollenzer <david.oberhollenzer@tele2.at>

2018-06-11[usyslogd] split off syslog parsingDavid Oberhollenzer
- Add proto.{h,c} for parsing of syslog message - Also parse time stamp in addition to priority Signed-off-by: David Oberhollenzer <david.oberhollenzer@tele2.at>
2018-06-11Add minimalistic syslog daemonDavid Oberhollenzer
For now this daemon simply dumps all syslog messages into seperate log files and doesn't do much parsing. Since the messages are readable ASCII anyway, this should not be to much of a problem and sufficient for debugging. Signed-off-by: David Oberhollenzer <david.oberhollenzer@tele2.at>
