#22211: Kernel problem with radius requests
------------------------------------------------+--------------------------
Reporter: tk@… | Owner: developers
Type: defect | Status: new
Priority: normal | Milestone:
Component: kernel | Version: Chaos Calmer
Keywords: kernel, radiusd, freeradius, loop, | 15.05
------------------------------------------------+--------------------------
When radiusd is getting requests via network, it will crash and loops with
messages like this:
{{{
Mon Apr 11 18:33:59 2016 : Info: Ready to process requests.
Mon Apr 11 18:33:59 2016 : Info: Ready to process requests.
Mon Apr 11 18:33:59 2016 : Info: Ready to process requests.
}}}
strace on the radiusd pid looks like this:
{{{
_newselect(9, [3 5 6 8], NULL, NULL, NULL) = 1 (in [5])
recvfrom(5, 0x7f809f04, 4, 2, 0x7f809e80, 0x7f809f00) = -1 EFAULT (Bad
address)
}}}
It seems, there is something bad with the kernel and memory addresses
passed to a system call.
About the setup:
freeradius 2.2.8-1 is running on TP-Link Archer C7 with CC 15.05.1.
Another Archer C7 node tries to authneticate a client via WPA2-enterprise.
Such request is running on the Archer C7 with radiusd. After the first
request, radiusd hangs in a loop. WPA2-enterprise requests from the same
node where the radiusd is running are just fine.
