Package: src:linux
Version: 3.16.7-ckt20-1+deb8u1
Severity: important
Dear Maintainer,
After updating the kernel with the latest security release FreeRADIUS
seem to be unable to process the UDP packets it is receiving. As you
can see in this strace there's some error occuring with the recvfrom()
that is triggered by the incoming packet. Downgrading the kernel to
linux-image-3.16.0-4-686-pae:i386 3.16.7-ckt11-1+deb8u6 makes it work
again.
This is a i686 domU on a X86_64 XEN host if that matters.
When using current kernel:
execve("/usr/sbin/freeradius", ["freeradius", "-s"], [/* 21 vars */]) = 0
brk(0) = 0x9e47000
access("/etc/ld.so.nohwcap", F_OK) = -1 ENOENT (No such file or
directory)

0) = 0xb77c5000
mmap2(NULL, 12288, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1,
0) = 0xb77c2000

When using the linux-image-3.16.0-4-686-pae:i386 3.16.7-ckt11-1+deb8u6
kernel - which is working:
select(10, [4 6 7 8 9], NULL, NULL, NULL) = 1 (in [6])
recvfrom(6, "\1\f\0\244", 4, MSG_PEEK, {sa_family=AF_INET,
sin_port=htons(39163), sin_addr=inet_addr("192.168.20.25")}, [16]) = 4
getsockname(6, {sa_family=AF_INET, sin_port=htons(1812),
sin_addr=inet_addr("0.0.0.0")}, [16]) = 0
recvfrom(6, "\1\f\0\244", 4, MSG_PEEK, {sa_family=AF_INET,
sin_port=htons(39163), sin_addr=inet_addr("192.168.20.25")}, [16]) = 4
getsockname(6, {sa_family=AF_INET, sin_port=htons(1812),
sin_addr=inet_addr("0.0.0.0")}, [16]) = 0
recvmsg(6, {msg_name(16)={sa_family=AF_INET, sin_port=htons(39163),

I don't have any clue as to what change has caused the problem though..
