ofp-actions: Centralize all OpenFlow action code for maintainability.

2014-08-11T19:57:17+00:00

Until now, knowledge about OpenFlow has been somewhat scattered around the
tree.  Some of it is in ofp-actions, some of it is in ofp-util, some in
separate files for individual actions, and most of the wire format
declarations are in include/openflow.  This commit centralizes all of that
in ofp-actions.

Encoding and decoding OpenFlow actions was previously broken up by OpenFlow
version.  This was OK with only OpenFlow 1.0 and 1.1, but each additional
version added a new wrapper around the existing ones, which started to
become hard to understand.  This commit merges all of the processing for
the different versions, to the extent that they are similar, making the
version differences clearer.

Previously, ofp-actions contained OpenFlow encoding and decoding, plus
ofpact formatting, but OpenFlow parsing was separated into ofp-parse, which
seems an odd division.  This commit moves the parsing code into ofp-actions
with the rest of the code.

Before this commit, the four main bits of code associated with a particular
ofpact--OpenFlow encoding and decoding, ofpact formatting and parsing--were
all found far away from each other.  This often made it hard to see what
was going on for a particular ofpact, since you had to search around to
many different pieces of code.  This commit reorganizes so that all of the
code for a given ofpact is in a single place.

As a code refactoring, this commit has little visible behavioral change.
The update to ofproto-dpif.at illustrates one minor bug fix as a side
effect: a flow that was added with the action "dec_ttl" (a standard
OpenFlow action) was previously formatted as "dec_ttl(0)" (using a Nicira
extension to specifically direct packets bounced to the controller because
of too-low TTL), but after this commit it is correctly formatted as
"dec_ttl".

The other visible effect is to drop support for the Nicira extension
dec_ttl action in OpenFlow 1.1 and later in favor of the equivalent
standard action.  It seems unlikely that anyone was really using the
Nicira extension in OF1.1 or later.

OF 1.1 set vlan vid/pcp compatibility.

2013-11-01T21:07:40+00:00

OpenFlow 1.1 set vlan actions only modify existing vlan
headers, while OF 1.0 actions push a new vlan header if one
does not exist already.

Implement IPFIX export

2013-04-22T21:33:58+00:00

Define a new NXAST_SAMPLE OpenFlow vendor action and the corresponding
OFPACT_SAMPLE OVS action, to do per-flow packet sampling, translated
into a new SAMPLE "flow_sample" dp action.

Make the userspace action's userdata size vary depending on the union
member used.  Add a new "flow_sample" upcall to do per-flow packet
sampling.  Add a new "ipfix" upcall to do per-bridge packet sampling
to IPFIX collectors.

Extend the OVSDB schema to support configuring IPFIX collector sets.
Add support for configuring multiple IPFIX collectors for per-flow
packet sampling.  Add support for configuring per-bridge IPFIX
sampling.

Automatically generate standard IPFIX entity definitions from the IANA
specs.  Send one IPFIX data record message for every packet sampled by
an OpenFlow sample action or received by a bridge configured with
IPFIX sampling, and periodically send IPFIX template set messages.

nicira-ext: Add Nicira actions NXAST_STACK_PUSH and NXAST_STACK_POP.

2013-03-06T21:40:28+00:00

The Push action takes a single parameter. Any source allowed by NXAST_REG_MOVE
is allowed to be pushed onto the stack. When the source is a bit field,
its value will be right shifted to bit zero before being pushed onto the
stack. The remaining bits will be set to zero.

The Pop action also takes a single parameter. Any destination allowed by
NXAST_REG_MOVE can be used as the destination of the action. The value, in
case of a bit field, will be taken from top of the stack, starting from
bit zero.

The stack size is not limited. The initial 8KB is statically allocated to
efficiently handle most common use cases. When more stack space is
required, the stack can grow using malloc().

Add support for set_mpls_ttl action

2013-03-06T16:50:43+00:00

This adds support for the OpenFlow 1.1+ set_mpls_ttl action.
And also adds an NX set_mpls_ttl action.

The handling of the TTL modification is entirely handled in userspace.
