Hello,
I merged the latest version of your patch.
Minor mangling : I had to rename your snprint_blacklist() rewrite to
snprint_blacklist_report() because the "show config" CLI command purpose
is to dump a config file in sync with the daemon actual configuration.
Your stealing the snprint_blacklist() fn name made for your blacklist
"report" to be included in this dump in place of the correct "blacklist
{}" block.
I also implemented the missing snprint_blacklist_exceptions() for config
dump completeness.
Please verify everything is still working for you.
Thanks for this nicely crafted work.
Regards,
cvaroqui
