Thanks for addressing this. I always wanted to get around to do it, but didn't
find time so far.

I think it would be best to introduce a new logging macro, and turn DEBUGP into
a backwards compatibility macro that then calls/uses the new logging macro to
print a DEBUG level message
There is some code for log file handling in ulogd
(http://git.netfilter.org/cgi-bin/gitweb.cgi?p=ulogd2), see ulogd_log() and
__ulog_log() in ulogd.h as well as __ulogd_log() in ulogd.c. It already
handles logging to a runtime choice of either syslog or a dedicated text file.
This is a feature that I'd like to see in openbsc, too.
In addition to that, we should support enabling of certain log levels and log
'groups' (like syslog facility, but more fine grained) to print to the telnet
interface.
So from the telnet interface, I want to be able to use vty commands to do
things like
* enable "WARNING" level messages on this telnet vty for all groups (MM, CC, ...)
* enable "DEBUG" level messages on this telnet vty for one specific group (SMS)
* change the log level and log groups for the logfile

yes.

all of those, plus
abis_nm needs formats for
* object class and object instance
* nm_state
since we probably need more and more of these, it might be interesting to think
of adding a new format character instead of %... % is already heavily used
especially in glibc.g
