This should fix problems with trying to log on a machine that doesn't have
openflow-pki installed (because such machines didn't have the pki
directory). Every machine needs the log directory.
This makes it easier to install the headers, or to use them directly from
another software package with -I$(openflow)/include, without invading
the top-level include file namespace.
Move vlog option descriptions into a separate file lib/vlog.man that
is substituted into manpages.
Get rid of individual rules for substituting most files in favor of
a single suffix rule. Unfortunately this loses the (Emacs-specific)
read-only markings but it simplifies the makefiles.
* New command-line options for configuring log files, hence:
- Centralized vlog usage messages.
* New vlogconf action for reopening log files.
* New vlogconf support for specifying a target by pidfile.
Make "make" behave properly when these are changed by re-running
"configure", by putting their definitions into a generated file that
depends on Makefile.
To enable SNAT, run configure with the "--enable-snat" flag. This has
only been tested with the 2.6.23 kernel...more diverse testing will follow.
Documentation and a cleaner build setup will also be in a future check-in.
Allow vendors to define their own actions. Actions were originally fixed-
length, which was a bit constraining. Actions now contain a length field,
which gives them more flexibility.
Stripping VLANs is now done through the OFPAT_STRIP_VLAN action (i.e., you
don't specify a magic value in the generirc VLAN action). Also, it is now
possible to modify the priority bits associated with the VLAN tag through
the OFPAT_SET_VLAN_PCP action. The OFPAT_SET_DL_VLAN has been renamed to
OFPAT_SET_VLAN_VID.
This new OpenFlow message format provides a cleaner interface and greater
detail and control over ports. It is now possible to see what features
the switch's port is currently configured as having, what it's advertising,
and what it's capable of handling. It is also possible to return the
features advertised by the port's peer.
This cleans up the handling of modifying existing flows. There now exists
OFPFC_MODIFY and OFPFC_MODIFY_STRICT commands, which have the same matching
characteristics to their OFPFC_DELETE* counterparts. When adding a flow that
already exists, the counters and timers are now reset (ie, its treated as a
new flow). This commit also adds the "--strict" option to dpctl to allow
strict matching for "mod-flows" and "del-flows".
This updates the OpenFlow protocol version and changes the names of
structure members, so any software that uses OpenFlow will need to be
updated to match.
