Hi All,
First post here; any pointers or improvements for bug reporting are
welcome.
[1.] One line summary of the problem:
sendmsg() with ancillary data of type IPV6_PKTINFO fails with invalid
argument and further possible memory corruption.
---------------------------------
[2.] Full description of the problem/report:
As part of my project I am attempting to perform IPv6 neighbour
solicitations to discover the MAC address of my local neighbours.
In the included test code link-local src and dst addresses are used to
send neighbour solicitations along with specifying the network interface
in IPV6_PKTINFO ancillary data.
In my test environment I have a Ubuntu 16.04 LTS Server/Router and a
Ubuntu 16.04 LTS Desktop.
These are both hosted on a Windows 10 Host as Virtual Guests.
Router/Server Interfaces:
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group
default qlen 1
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state
UP group default qlen 1000
link/ether 08:00:27:c5:0e:76 brd ff:ff:ff:ff:ff:ff
inet 10.0.2.15/24 brd 10.0.2.255 scope global eth0
valid_lft forever preferred_lft forever
inet6 fe80::a00:27ff:fec5:e76/64 scope link
valid_lft forever preferred_lft forever
3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state
UP group default qlen 1000
link/ether 08:00:27:0a:c1:80 brd ff:ff:ff:ff:ff:ff
inet6 2001:db8:1000:baba::1/64 scope global
valid_lft forever preferred_lft forever
inet6 fe80::a00:27ff:fe0a:c180/64 scope link
valid_lft forever preferred_lft forever
Eth0 is set up for NAT to a physical IPv4 network but is unused in this
test setup.
Eth1 is IPv6 and is the radvd interface attatched to an internal virtual
box network interface.
In my client environment I have three network interfaces:
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group
default qlen 1
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: enp0s3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast

4: enp0s9: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast

enp0s3 is a bridged physical wired connection on the host to an ipv4
network with router / gateway, ipv6 is active but not used.
enp0s8 is a bridged physical wifi connection on the host to another ipv4
subnet within the same network on the same router / gateway ipv6 is active
but not used .
enp0d9 is an internal virtual box network connected directly to another
Ubuntu guest as an IPv6 stateless router (the neighbour I am solicitating)
this interfaces is ipv4 enabled but not used.
The expected behaviour is to use the sendmsg() system call and specify the
outgoing interface for the neighbour sonication message using the
IPV6_PKTINFO ancillary data as detailed in the RFC3542 links below.
6.1. Specifying/Receiving the Interface
https://tools.ietf.org/html/rfc3542.html#section-6.1
6.7 Summary of Outgoing Interface Selection
https://tools.ietf.org/html/rfc3542.html#section-6.7
The actual behaviour is for the sendmsg() system call to fail with errno
set to 22, Invalid Argument.
A note of interest is that if a perror() call is made to report this
problem a seg fault in mallo.c is encountered. I have not performed
further investigation.
You can see this has been commented after the sendmsg() system call in the
demo code.
Warning:
In my testing I have removed the IPV6_PKTINFO ancillary data and have
found that if the IPv6 router is not available at boot by default enp0s3
is used to send the packet.
I will send another e-mail further describing the behaviour with the
subject:
