- add __vxlan_tunnel_has_diff() to align with the other _has_diff()
methods
- factor out a few repetitive occurences of l2xc creations
- strictly make "cli=" the pattern instead of "cli = ", to help grepping :)
- based on previously submitted schema and validation, can add a TAP
with host netns, bridge and MTU.
- detect diffs in __tap_has_diff(), used to prune TAPs that must change
- add prune_taps() and create_taps() in the reconciler
- add Dumper() logic to emit YAML config for TAPs
- Move tap_is_lcp() into the VPPApi() class, so it can be reused
Add lots of test cases in intest/*.yaml and example.yaml - full
regression and integration and unit/YAML tests pass on this change.
- Cannot have LCP, Address or Sub-Interface
- Cannot be PHY
- Cannot be Bond member
- Can be target of L2XC
- Can be member of Bridge
- interface.mtu must be the same as tap.host.mtu
Add YAML tests for common mistakes. This unblocks taps becoming members
of a bridgedomain, and allowing a very cool feature: slowpath networking!
VPPApiDumper() is its own file, preparing for VPPApiApplier() in an
upcoming commit. VPPApi() itself remains read-only. No need for an empty
__init__.py file.
Update vppcfg to use the correct vpp/dumper.py import
Special care is taken for bondethernet, where the MAC changes when
the first member is added to it. BondEthernet requires its MAC to
be set in the bondethernets section, disallowing the MAC of individual
members to be set.
Also write a dumper for MACs of all types. Update integration test
cases to stress the MAC changes on loops, bonds, and phys.
Add int_to_mode() and int_to_lb() in config/bondethernet.py to map back
the retrieved values from VPP into their config strings.
Implement bond and bridge settings dumper, dumping all settings even if
they are default. This helps the user understand the configurable
options.
This requires a schema change, adding 'mode' and 'load-balance' fields,
a semantic invariant that 'load-balance' can only be set in the case of
LACP and XOR bonds, a mapper from the mode/lb strings, ie.
"round-robin" to their VPP numeric counterparts, a bunch of unit tests.
Then in the reconciler, changing bonds (__bond_has_diff()) will
invalidate any LCP or sub-interfaces built on them, so those will have
to be pruned. create_bondethernet() will now create (or re-create)
the bond with the correct flags.
Unit-tests, YAML tests and the integration test all pass.
Updated config-guide.
TIL! Using the existence of obscure member sys._MEIPASS, I can detect if
we're running from a bundled PyInstaller binary, versus running from Python
directly.
Add schema.yaml to the datas of the PyInstaller spec. Then, if the
-/--schema flag is given, use it, and if it's not given, default to the
built-in one if we're running from a bundled binary, or fall-through to
./schema.yaml in other cases.
This avoids the need for config/schema.py as a carbon-copy of the schema,
slick!
Bridges can be created with default settings, with specific settings,
and they can be sync'd at runtime with all of the settings in this
change.
Notably missing are two features:
- unknown unicast flooding into specific interfaces (as opposed to
on/off on the bridge)
- learn-limit, which does not have an API getter, only a setter.
