b2fc336833 plugins/host-local: ensure subnet is a network address
Allocation code assumes the specified subnet is a clean network address
prefix, so check that is the case and throw an error otherwise

Fixes #161

731298003c plugins/testutils: pass CNI_CONTAINERID to plugins in testcases
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.

47668f6d64 host-local: Update host-local IPAM to support Windows 2017-11-11 15:17:45 -08:00
27d027a6d3 ipam/host-local: support sets of disjoint ranges
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

0da6780449 pkg,plugins: update for Result struct Interface index changes
It's a pointer now, so we need to use the helper function to set
the field and also test for nil before accessing it.

2e9e87732f ipam/host-local: support multiple IP ranges
This change allows the host-local allocator to allocate multiple IPs.
This is intended to enable dual-stack, but is not limited to only two
subnets or separate address families.

13824487c6 plugins/*: Don't error if the device doesn't exist
I wasn't able to test or update the dhcp plugin but from a code read it
should be fine. All the other plugins are tested and fixed

d5acb127b8 spec/plugins: return interface details and multiple IP addresses to runtime
Updates the spec and plugins to return an array of interfaces and IP details
to the runtime including:

- interface names and MAC addresses configured by the plugin
- whether the interfaces are sandboxed (container/VM) or host (bridge, veth, etc)
- multiple IP addresses configured by IPAM and which interface they
have been assigned to

Returning interface details is useful for runtimes, as well as allowing
more flexible chaining of CNI plugins themselves.  For example, some
meta plugins may need to know the host-side interface to be able to
apply firewall or traffic shaping rules to the container.

5cde14cd7b ipam/host-local: add ResolvConf argument for DNS configuration
This adds the option `resolvConf` to the host-local IPAM configuration.
If specified, the plugin will try to parse the file as a resolv.conf(5)
type file and return it in the DNS response.

76028d7f8c host-local: trim whitespace from container IDs and disk file contents
It doesn't seem like container IDs should really have whitespace or
newlines in them.  As a complete edge-case, manipulating the host-local
store's IP reservations with 'echo' puts a newline at the end, which
caused matching to fail in ReleaseByID().  Don't ask...

e085226f82 host-local: add DataDir IPAM conf option and use it for testcases
Add an e2e host-local plugin testcase, which requires being able
to pass the datadir into the plugin so we can erase it later.
We're not always guaranteed to have access to the default data
dir location, plus it should probably be configurable anyway.
