I can confirm this. This bug hit us for Windows clients which suddenly
could no longer authenticate via EAP-TLS or 802.1x. It seems that it
has something to do with large UDP packets. Freeradius did no longer
process UDP packets that were fragmented.
This was also reported by someone else for the freeradius package as
bug 808293.
We tested the following versions:
Affected:
linux-image-3.16.0-4-amd64 3.16.7-ckt20-1+deb8u1
linux-image-3.2.0-4-rt-amd64 3.2.73-2
Not affected:
linux-image-3.2.0-4-rt-amd64 3.2.71-2

Sebastian
