File openbsc/src/ipaccess/ipaccess-config.c:

Line 629: 	load->file_id_len = strlen((char*)load->file_id) + 1;
> Why +1? The \0 added by osmo_strlcpy() is included in size parameter for it
I'm a bit confused, what are you saying?

The sizeof() passed to osmo_strlcpy() has no +1, obviously.

load->file_id_len is an indicator to the rest of the program, I'm not going to change the meaning of this value, which was, apparently, and still is "strlen() + 1".

If you'd like me to use osmo_strlcpy()'s return value instead of strlen(): actually osmo_strlcpy returns the length of the input string, not the length copied; neither does that include the \0. I tried to add an osmo_str*cpy that has an actually useful return value once, but discussion around that dragged on too far to be worth it.
