This file was intended to be used by VPN plugins (by copying it). However, it was also used internally. Split the file, and move the internally used part to libnm-glib-aux. The part that is only there for out of tree users, moves to "nm-compat.h".

/* NetworkManager uses internally NMLogLevel levels. When spawning
|
|
* the VPN plugin, it maps those levels to syslog levels as follows:
|
|
*
|
|
* LOGL_INFO = LOG_NOTICE,
|
|
* LOGL_DEBUG = LOG_INFO,
|
|
* LOGL_TRACE = LOG_DEBUG,
|
|
*
|
|
* However, when actually printing to syslog, we don't want to print messages
|
|
* with LOGL_INFO level as LOG_NOTICE, because they are *not* to be highlighted.
|
|
*
|
|
* In other words: NetworkManager has 3 levels that should not require highlighting:
|
|
* LOGL_INFO, LOGL_DEBUG, LOGL_TRACE. syslog on the other hand has only LOG_INFO and LOG_DEBUG.
|
|
*
|
|
* So, coerce those values before printing to syslog. When you receive the syslog_level
|
|
* from NetworkManager, instead of calling
|
|
* syslog(syslog_level, ...)
|
|
* you should call
|
|
* syslog(nm_utils_syslog_coerce_from_nm(syslog_level), ...)
