So, there is a piece of code in rlm_radutmp.c/radutmp_checksimul():
radutmp_unlock(fd);
rcode = rad_check_ts(u.nas_address, u.nas_port, login,
session_id);
radutmp_lock(fd);
if (rcode == 1) {
++request->simul_count;
/*
* Does it look like a MPP attempt?
*/
if (strchr("SCPA", u.proto) &&
ipno && u.framed_address == ipno)
request->simul_mpp = 2;
else if (strchr("SCPA", u.proto) && call_num &&
!strncmp(u.caller_id,call_num,16))
request->simul_mpp = 2;
}
else {
/*
* False record - zap it.
*/
session_zap(u.nas_address, u.nas_port, login,
session_id, u.framed_address,
u.proto, 0);
}
If rad_check_ts() returns 1 (dup found), and no multilink is there, this code
simply increments request->simul_count, but if not, it does session_zap() (and
generates "fake" Accounting-Stop record with fields such in my case). So it
seems to be a problem in rad_process().
