[SR-Users] lookup(aliases) issues with 5.2

[Henning Westerholt]

Hello Igor,

the problem is that this code belongs to the core parser part, it is not something usrloc module related.

If you need a workaround, probably the easist and fastest option would be to just build an own kamailio without this change (e.g. apply the patch in reverse mode).

Cheers,

Henning

Hello,

Hmm, ok. Saw it.
Is it possible to reconsider a less strict control?

Regards,

Igor.

Hello,

reading again I see that the error with the host uri is printed from the C code. I thought of another issue that was reported related to IPv6 addresses in the URI that kamctl rejected.

The problem is that the underscore is not allowed in hostname: the relevant standard is RFC 1123, section 2.1 "Host Names and Numbers" which limits host names to letters-digits-hyphen.

I checked the commits log and it seems this more strict verification was added by next commit:

commit 4994960324d5353222b3de08515bed07802ab7bc

    core/parser: more strict parsing of sip uri host

Regarding the $ALL_METHODS not being defined, iirc, you should set it to . (or maybe -1 in this case).

Cheers,
Daniel

Hello Daniel,

We moved to the latest 5.2.4 but hostname with underscore are still not handle properly.
Is it a real design choice or a mistake somewhere in the code that handle domain name?

Igor.

We will update with 5.2.4 and I'll let you know if it's solved.

Hello!

Any help on that matter? Sounds like the domain parsing have been updated. Is it possible to back on the previous mode?

did you mean backporting to older branches? If yes, it was done to branch 5.2, have you tried with latest version in that branch?

Cheers,
Daniel

Objet : lookup(aliases) issues with 5.2

Hello!

I have notice some issues with lookup(aliases) since I upgraded to 5.2 from 5.1:
First with kamctl: If this default command is executed:

ctl_cmd_run ul.add "$USRLOC_TABLE" "$OSERUSER@$OSERDOMAIN" "$2" \
"$UL_EXPIRES" "$DEFAULT_Q" "$UL_PATH" "$UL_FLAGS" "$BR_FLAGS" "$ALL_METHODS"

as $ALL_METHODS is not defined, there is a huge value in methods and then lookup(aliases) fails with -2.

I have to update kamctl script and put -1 ("-1") instead of the variable. So, now, methods is a NULL value in DB and my alias is not ignored. But I use to make my alias like this: sip:number at blabla_1.local
Which is no longer works: ERROR: registrar [common.c:62]: extract_aor(): failed to parse AoR [sip:number at blabla_1.local]

Any idea of the difference since 5.2 with this behaviour? Without the underscore, the AoR seems to be valid but I need to support underscore as before.

Regards,

Igor.
