mapping ECMLenght oscam.whitelist

Oscam incorrectly interepret mapping entry with ECMLength
I have configure in oscam.whitelist:
m:0100:000068::::6A 1813:000068

But Oscam is ignoring ECMLenght
(config) whitelist: m: 0100@000068:0000:0000:0000:00 map to 1813@000068

Finaly map everithing from 0100

Your log must prove it so post your log contain error, no log or no error in log and ticket is invalid.

you're right robert_cz, the ecmlength was ignored since introducing in #6606 :)

@savan: he post the example with the corrosponding log-part.

i just fix the part of getting the ecmlength from m:-line, i didnt check the function of mapping with matching ecmlegth.

Let us discuss / test it @ ​https://board.streamboard.tv/forum/thread/47709-oscam-whitelist-mapping-ecmlength-ticket-4822/

I have test this patch, and map is working correctly in the mapping. Map only defined lenght. With one but. If the origin of the ECM for mapping is from DVBAPI and we mapping for example 0100 to 1813 DVBAPI is responding that is not interesting about the answer for 1813. Looks that for dvbapi answer for ECM must to be reversely translated:

What do you think to add this patch to the oscam?
Mapping with ECMlenght is very useful
