accel-ppp daemon crashes
Closed, ResolvedPublicBUG

Description

accel-ppp has a configuration:

[common]
single-session=deny
[ipoe]
verbose=1
interface=re:^bond1\.[0-9]*$,shared=0,mode=L2,ifcfg=1,start=up,start=dhcpv4,roxy-arp=1,ip-unnumbered=1

When a subscriber host sends packets from several different IP addresses before authentication session, accel-ppp daemon crashes.

Subscriber’s host sends packets with several different source IP addresses, accel-ppp requests access for each IP in the Radius. Accel-ppp receives Access-Accept and session starts.
But after starting a session, accel-ppp no longer expects an Access-Accept radius. After receiving the second Accel-Accept, the daemon crashes.
