IAX configuration duplicated by res_phreaknet

[ssterling]

iax.conf, as well as every file included by iax.conf (for me, in iax.d/), is duplicated when res_phreaknet tries to fetch new RSA keys on Asterisk restart. This only started today, and I haven’t updated anything. The following is a log from after I deleted all the duplicate contexts:

Frankly, I’m having trouble wrapping my head around res_phreaknet.c, and I thought y’all might know what’s going on.

[InterLinked1]

The use of a separate iax.d directory is new to me in this context... if you have them all in the same directory, does this still happen?

[ssterling]

Yes, it still happens. I’m thinking it has something to do with wildcards, because, with there now being an #include "iax-*.conf, there’s now a file called iax-*.conf being made. Including the files one-by-one, however, solves the problem, although maintaining that list will be tedious. Logs are now as such:

There’s now this annoying header in each IAX-related file, though:

;!
;! Automatically generated configuration file
;! Filename: iax.conf (/etc/asterisk/iax.d/cnet.conf)
;! Generator: res_phreaknet
;! Creation Date: Thu Sep 11 08:38:27 2025
;!

I think this is very possibly a bug in Asterisk's config APIs, not in res_phreaknet. At least, I'm not seeing anything that could have to do with wildcards, and the config APIs have been known to be buggy in different ways.

(I've asked someone to give his opinion on this)

[Allan-N]

@ssterling You don't mention what version of Asterisk you are running. There were issues with Asterisk's config APIs with #include / #tryinclude statements. If you are running a recent -20, -21, -22 build you should be OK (you'd need the changes from asterisk/asterisk#918).

@InterLinked1 Looks like res_phreaknet includes a few calls to ast_config_text_file_save2() ... and it's that API call that triggers all of the updates.

As for the "Automatically generated" header updates, I agree that they are annoying. Seems like the config APIs should be smart enough to leave a file alone if there were no changes.

[InterLinked1]

@ssterling Please confirm if you have the latest version and the patches Allan mentioned.

Seems like the config APIs should be smart enough to leave a file alone if there were no changes.

I would agree on that too.
