interfaces using dhcp ipam.
Vendor latest dhcp4server, dhcp4client, dhcp4
Added additional tests for new functionality in dhcp2_test.go
Wrap d2g dhcp4client calls with our own which add clientID to packet.
Add two interfaces (e.g. eth0, eth1) to the same container.
Ensure each file now has ContainerID and ifname.
Delete one, ensure that the right file was deleted.
Add an interface using just ContainerID in the file.
Delete to verify we are still backwards compatible with any
files created using earlier verison of host-local plugin.
This change is to add CNI_ARGS support in static IPAM plugin.
When IP/SUBNET/GATEWAY are given in CNI_ARGS, static IPAM adds
these info in addition to config files.
To configure ip address only from CNI_ARGS, 'address' field in config
is changed to optional from required.
Recent CNI specification changes require the container ID on ADD/DEL,
which the testcases were not providing. Fix that up so things work
when this repo gets CNI revendored.
Namespace creation had an unergonomic interface and isn't used, except
for testing code. Remove it; downstream users should really be creating
their own namespaces
Don't lock around the Stop() operation though, as that may take
a while and block other operations. That may mean we call Stop()
multiple times, but the Lease object should handle that correctly
itself.
Classless static routes (DHCP option 121) are now processed first.
If CSRs exist, static routes (DHCP option 33) and the gateway default
route are ignored as per RFC 3442.
This diff adds -hostprefix option in dhcp daemon. This option
could be used to run dhcp daemon as container because container
cannot touch host's netns directly. The diff changes dhcp daemon
to touch procfs mounted to another path, like '/hostfs/proc'.
- start list of linux_only plugins; ignore them when testing on Windows
- Isolate linux-only code by filename suffix
- Remove stub (NotImplemented) functions
- other misc. fixes for Windows compatibility
There are at least two reasons why a lease is not present:
* The dhcp ipam daemon was restarted
* On add the IPAM plugin failed
Don't fail the IPAM invocation when the lease is not present, to allow
proper device cleanup on CNI delete invocations.
In real-world address allocations, disjoint address ranges are common.
Therefore, the host-local allocator should support them.
This change still allows for multiple IPs in a single configuration, but
also allows for a "set of subnets."
Fixes: #45
