Package: hostapd
Version: 2:2.7+git20190128+0c1e29f-6
Severity: normal
Tags: patch
Dear Maintainer,
I'm just starting out with hostapd, so I'm using DAEMON_OPTS="-d" to
configure debug output and help me find my mistakes. Unfortunately, the
systemd journal abruptly stops, presumably because hostapd forks and
daemonizes. Syslog support does not seem to be compiled in, so I think
the only way to get debug information is to prevent the daemonization. I
have attached a patch to configure the systemd units this way; further
information in in the patch.
Thanks,
Corey

change systemd units to use "exec" service type
This makes it possible to view debug messages from the -d option during
operation.
When hostapd forks and daemonizes, messages on stdout cease; since the
Debian build does not enable logs via syslog, there is no way to get any
debug information past the initial startup.
If hostapd is configured not to fork, then the debug information remains
visibile for the lifetime of the eprocess.
There is some history here:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=918861
This takes the other approach mentioned in the ticket, at the cost of
systemd thinking the service has started a bit earlier. I think the
tradeoff is worthwhile.
