- Status changed from New to In Progress
Michael,
this might become complicated ;-)
The error clearly happen in the external asn1-ber library of the ldap server.
Two people made changes there during the last year (one of them was myself ^^).
We need a reliable reproduction case. I might be wrong, but my guess is that it might have something to do with special (unicode) characters, like German "umlaut". Either in the search request or the response. Unfortunately in general I already test them in my test-cases. So either I missed a tested somewhere or it's a very special or broken character.
Looking forward...

Hallo Jörg,
es passiert beim Reverse-Lookup, ich in dem Reverse Lookup ist mein
Eintrag und zwei Namen mit Umlauten (Wörner, Müller).
Ich kann es reproduzieren, jedesmal wenn ich mir die Einträge im in der
"Anrufliste" anschaue passiert der crash, danach muss ich dann die N670
rebooten.
Hie nochmal ein Crash mit "Debug" Flag an:

Hallo Jörg,
es passiert beim Revers-Lookup der Anrufliste und eben ist es auch noch
beim Aufruf der Intern Liste (ein weiteres CARDDAV Adressbuch) passiert,
ich denke die letzte Mail war nicht rausgegangen, hängt auch mit dran.

Hallo Jörg,
es passiert beim Reverse-Lookup, ich in dem Reverse Lookup ist mein
Eintrag und zwei Namen mit Umlauten (Wörner, Müller).
Ich kann es reproduzieren, jedesmal wenn ich mir die Einträge im in der
"Anrufliste" anschaue passiert der crash, danach muss ich dann die N670
rebooten.
Hie nochmal ein Crash mit "Debug" Flag an:

Michael,
thanks a lot for the detailed info.
I build some additional tests with special German chars, but couldn't get L2CPBG to crash.
Could you please export me the VCF of the contact which let him crash during the reverse lookup?!
Send it as "Privater Kommentar" (under the edit box) or by Mail.
Also feel free to change the sensible information like phone number before sending the VCF.
In addition I built a debug version which prints the search-result directly before it get forwarded to the LDAP-Server.
Please be so kind, start it with "trace" logging level, fire the critical reverse lookup so that L2CPBG crashes and send me the result.
One last questions:
Do you have an idea why this crashes doesn't happen the days before?
Cheers
Jörg

Hi Michael!
Here's a special version with debugging info about the connection packages which crashes the ASN1-Ber package decoding. With this infos, I should be able to debug, and hopefully fix, the crashes.
Logging level debug is enough.
Please install, let it crash and drop me the log.
Looking forward for the logs... and... thanks a lot for your ongoing support!!

Hi Michael.
Thanks a lot for the debug log. It was very helpful.
I've been able now to identify the crash-packet. At the moment I've the impression that it is a broken/wrong packet, in special because also others @ github already detected such packets.
So I hardened the ASN1-Ber library for such packets so that it's not crashing anymore... at least for this kind of LDAP search request.
We should see now a "handleConnection ber.ReadPacket ERROR: ..." instead of the crash.
Not sure how your N670 will handle this, but L2CPBG should stay alive and with the new error we possibly might identify the kind of search request.
Looking forward to your feedback! ;-)
