Problem with WISPr in release 1.0.13

[Rodrigo Martínez]

Hello,
    We are using CoovaChilli release 1.0.13 in a solution for access 
control system. We have smart clients that authenticate using WISPr 
protocol to communicate with the CoovaChilli. We start using CoovaChilli 
release 1.0.12, with this version the WISPr communication worked fine, 
but when we update to release 1.0.13 the client stop connecting.

    Analyzing the problem we found that in the new release, when the 
redirect message is send (302 page was moved), the WISPr message had two 
tags with the LoginURL. One of the tags had the same value as in release 
1.0.12 and the second one has some differences. The main problem of the 
second tag is that the "&" it is not scaped, so when we check syntax 
against the xsd, it always fail. Looking around in the code, we found 
the piece of code that was generating the WISPr message and we modify it 
to match the WISPr standard. Attached in the mail we are sending the 
file with the patch that contains the modifications in the redir.c file. 
We hope this can help developers to fix this problem in next releases.

    Thanks in advance

    Regards,
       Rodrigo
