ovs_assert, tests: Support NDEBUG.

2014-10-30T16:14:46+00:00

./configure accepts --enable-ndebug option.  Make ovs_assert() honor
it, and make sure all test programs disable it.

The order of include files in test programs is also made uniform:

1. #include 
2. #undef NDEBUG
3. Include file of the test subject (to make sure it itself has
   sufficient include directives).
4. System includes in alphapetical order.
5. OVS includes in aplhapetical order.

unit-test: Link 29 test programs into ovstest

2014-04-03T18:17:17+00:00

Improve link speed by linking 29 test programs into ovstest.

On my machine, running the following command against a fully
built tree:

  $ touch lib/random.c; time make

Improve the overall build time from 7 seconds to 3.5 seconds.

Rename NOT_REACHED to OVS_NOT_REACHED

2013-12-17T21:16:39+00:00

This allows other libraries to use util.h that has already
defined NOT_REACHED.

More accurate wildcarding and fragment handling.

2013-10-17T22:08:05+00:00

This patch gets rid of the need for having explicit padding in struct
flow as new fields are being added.  flow_wildcards_init_exact(), which
used to set bits in both compiler generated and explicit padding, is
removed.  match_wc_init() is now used instead, which generates the mask
based on a given flow, setting bits only in fields which make sense.

Places where random bits were placed in struct flow have been changed to
only set random bits on fields that are significant in the given context.
This avoids setting padding bits.

- lib/flow:
  - Properly initialize struct flow also in places we used to zero out
    padding before.
  - Add flow_random_hash_fields() used for testing.
  - Remove flow_wildcards_init_exact() to avoid initializing
     masks where compiler generated padding has bits set.
- lib/match.c match_wc_init(): Wildcard transport layer fields for later
  fragments, remove match_init_exact(), which used
  flow_wildcards_init_exact().
- tests/test-flows.c: use match_wc_init() instead of match_init_exact()
- tests/flowgen.pl: generate more accurate packets and flows when
  fragmenting, mark unavailable fields as wildcarded.

Remove mpls_depth field from flow

2013-09-27T16:18:06+00:00

Rather than tracking the MPLS depth as a field in the
flow, which is an entirely poor place for it, just track
the delta to the MPLS depth during translation.

This logic was developed while implementing recirculation
and intended to be used to detect when recirculation should
occur. This variant of the patch uses the logic to determine
if processing of actions should stop due to an MPLS
action which cannot be translated (without recirculation).

A side-effect of this patch is that it resolves a bug
whereby ovs-vswitchd will abort due to to an assertion
on eth_type_mpls(ctx->xin->flow.dl_type) in compose_mpls_pop_action(()
if the actions of a flow include pop_mpls twice without
a push_mpls in between.

ofp-parse: Do not exit() upon a parse error.

2013-07-08T17:15:00+00:00

Until now, failure to parse a flow in the ofp-parse module has caused the
program to abort immediately with a fatal error.  This makes it hard to
use these functions from any long-lived program.  This commit fixes the
problem.

ofproto-dpif: Store relevant fields for wildcarding in facet.

2013-06-11T20:03:50+00:00

Dynamically determines the flow fields that were relevant in
processing flows based on the OpenFlow flow table and switch
configuration.  The immediate use for this functionality is to
cache action translations for similar flows in facets.  This yields
a roughly 80% improvement in flow set up rates for a complicated
flow table.

More importantly, these wildcards will be used to determine what to
wildcard for the forthcoming kernel wildcard (megaflow) patches
that will allow wildcarding in the kernel, which will provide
significant flow set up improvements.

The approach to tracking fields and caching action translations in
facets was based on an impressive prototype by Ethan Jackson.

User-Space MPLS actions and matches

2013-02-05T17:17:45+00:00

This patch implements use-space datapath and non-datapath code
to match and use the datapath API set out in Leo Alterman's patch
"user-space datapath: Add basic MPLS support to kernel".

The resulting MPLS implementation supports:
* Pushing a single MPLS label
* Poping a single MPLS label
* Modifying an MPLS lable using set-field or load actions
  that act on the label value, tc and bos bit.
* There is no support for manipulating the TTL
  this is considered future work.

The single-level push pop limitation is implemented by processing
push, pop and set-field/load actions in order and discarding information
that would require multiple levels of push/pop to be supported.

e.g.
   push,push -> the first push is discarded
   pop,pop -> the first pop is discarded

This patch is based heavily on work by Ravi K.

vswitchd: fix 32-bit builds

2012-11-23T01:44:21+00:00

My previous 72e8bf28bb38e8816435c64859fb350215b6a9e6 (datapath:
add skb mark matching and set action) commit broke 32-bit builds.
This patch assures that size of struct flow is equal on both
32-bit and 64-bit architectures so that build asserts would
not fire anymore.
