PS8: I'm sorry that I'm late for this patch review. This patch has a number of rough edges, I would welcome if we could revert it and get some more review cycles.

File src/sockaddr_str.c:

https://gerrit.osmocom.org/c/libosmocore/+/28992/comment/6219adc6_145bfcb8 PS8, Line 547: * buf_len >= 2: (hostA|hostB|...|...) buf_len is the buffer size of the output string buffer *buf. A buf_len == 0 cannot return any "()" string, it has zero size. buf_len == 1 cannot contain "hostA".

Did you mean sa_str_count?

https://gerrit.osmocom.org/c/libosmocore/+/28992/comment/d27293a9_acbb2b9e PS8, Line 555: int osmo_sockaddr_strs_to_str(char *buf, size_t buf_len, const struct osmo_sockaddr_str **sa_str, size_t sa_str_count) i find it odd that you want to pass an array of osmo_sockaddr_str POINTERS, instead of an array of osmo_sockaddr_str instances. i.e. i would expect an arg like 'const struct osmo_sockaddr_str *sa_strs', not '**'.

https://gerrit.osmocom.org/c/libosmocore/+/28992/comment/316d840f_674d4fd8 PS8, Line 562: return -ENOMEM; this check should not be here. The idea is to always return the nr of characters needed to output the full string, regardless of the underlying buffer length. If you return -ENOMEM on some specific buffer lengths, you destroy the ability of finding a sufficient buffer length from the return value. The OSMO_STRBUF macros deal with all cases of insufficient buffer length, just let it play through to the end, so that the proper sb.chars_needed is returned.
