This patch series adds IPv6 support to OSv.
The first 5 parts of the series should have no impact on existing
OSv code. The rest of the patches starting from the net channel
changes do impact existing code.
All parts should compile and test without issues, but IPv6 is only
enabled with the last patch in the series.
The IPv6 support is optional and can be enabled/disabled using the
conf-INET6 option in the conf/base.mk file.
Currently there are 2 known remaining issues left which are due to
limitations of the FreeBSD 9.0 IPv6 code which this code is base off of.
1. The NDP code is not thread safe
The FreeBSD 9.0 IPv6 code is not MPSAFE and expects callouts to run
with the giant lock and uses splnet() to ensure thread safety.
Unfortunatley OSv does not support these mechanisms and it is pretty
tricky to modify the FreeBSD 9.0 IPv6 code to make it thread safe
without them due to multiple locks required in the NDP code.
2. IPv6 MAC cache entries can expire causing extra neighbor solicits
This does not occur when using TCP sockets which keep the cache
entry active using ND6_HINT() but can occur for UDP or raw IP.
These issues appear to be fixed in FreeBSD 11, however back porting these
fixes is pretty involved and impacts a lot of the existing FreeBSD
code not only IPv6.
IPv6 Stateless Autoconfiguration is enabled, but has not been tested yet.
DHCPv6 is not supported yet.
Static IPv6 addresses may be configured using command line arguments:
./scripts/run.py --execute \
"--ip=eth0,2001:1:1::501,64 --defaultgw=2001:1:1::1 \
/tools/iperf -s -V -B ::"
or using cloud-init network version 1 yaml which is also added with
this patch series:
#cloud-config
network:
version: 1
config:
- type: physical
name: eth0
subnets:
- type: static
address: 2001:1:1::501/64
