Hello, There is a bug in 3.0.2. Get the latest version of libradius.h which fixes the issue : https://github.com/FreeRADIUS/freeradius-server/commits/v3.0.x/src/include/l... Then rebuild rlm_perl. Regards, Nicolas.

Hi,
some recent change seems to have broken the "rlm_perl" attribute handling. For a string, instead of adding a scalar value with appropriate length, it seems the whole buffer (including 0-byte) is inserted into the Perl hash. Consider this authorize() method:
sub authorize { $RAD_REPLY{'Reply-Message'} = "Username >>".$RAD_REQUEST{'User- Name'}."<<"; return RLM_MODULE_UPDATED; }
This leads, wrongly, to a prematurely terminated string:
rlm_perl: Added pair Reply-Message = Username >>user
When you add a line like this at the beginning of the subroutine:
$RAD_REQUEST{'User-Name'} =~ s/\0//g;
...then you'll receive the typical garbage that's in uncleared memory:
rlm_perl: Added pair Reply-Message = Username >>user ??"c¨?ìå ??...
Somehow, the length computation of the SVs must be fixed, but I don't know what broke it or how to repair it...
Any help appreciated, thanks in advance!
Julius
