Justin Pettit 77c8eed5b4 First cut of pretty printer of ofp_port_mod messages. 2008-09-22 17:59:50 -07:00
Justin Pettit 9da88ee2ad Modify OpenFlow commands related to ports to be more expressive. 
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.

Ben Pfaff 512f02d405 Get rid of per-port STP implemented bits, by reducing OFPP_MAX to 255. 
802.1D Spanning Tree Protocol supports a maximum of 255 ports per bridge,
but OpenFlow supported 256, so 1 port had to not implement STP.  This
gets rid of the problem by reducing the maximum number of ports to 255.

Justin Pettit cade93d46d Slight improvement to printing of ofp_port_status messages. 2008-09-19 02:00:06 -07:00
Justin Pettit 034f125955 Added lookup count to ofp_table_stats. 2008-09-18 19:47:27 -07:00
Ben Pfaff 03a3cc1e3d Fix failure to back off when vconn_open() fails immediately. 
This typically would happen only with an entirely local vconn,
e.g. connecting to a Unix domain socket vconn.

Justin Pettit e4cf5c4b82 Added OFPFC_MODIFY_STRICT flow mod command. 
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".

Ben Pfaff 331f82fd49 Change STP parameters to the minimum values allowed by 802.1D. 
This makes the secchan start up much faster.

Ben Pfaff f593e3ab70 Merge branch "partner", to simplify partner integration. 2008-09-15 15:31:36 -07:00
Justin Pettit 57d5205765 Add support for OFPFC_MODIFY Flow Mod command. 
The OFPFC_MODIFY command allows the controller to modify the actions of
existing flows.  When it does this, it does not reset counters or timers.

Ben Pfaff 9c1b16772c Implement OFPT_HELLO simple version negotiation. 2008-09-15 14:29:53 -07:00
Ben Pfaff 553dfa572d Break passive vconns out into separate pvconn routines and data structures. 
There really was nothing in common between the active and passive vconns.
This arrangement makes more sense.

Ben Pfaff 9fe9a47916 Make "struct vconn" opaque. 2008-09-15 14:29:53 -07:00
Ben Pfaff c2eb869bdb Use vconn_init() instead of explicit initialization in one last place. 
Commit b5e16b0723, "Respin "Make vconns keep track of their names and
include them in log messages,"" was supposed to do this everywhere, but
this instance was evidently missed.

Ben Pfaff d0fb7347b9 Delete OFPST_SWITCH and make it available as a Nicira vendor extension. 2008-09-10 15:00:47 -07:00
Justin Pettit 176265ed07 Use new method to describe table entries in OpenFlow wire protocol. 
Older versions of OpenFlow pre-defined a few different types of tables and the
Features Reply message would indicate how many of those entries existed.  This
was very inflexible, so now the Features Reply just indicates how many tables
there are.  The controller now sends a Table Stats request to find out how
many entries are supported and the fields that can be wildcarded.

This change also removes the "buffer_mb" field from the Features Reply, since
it was not being used and seemed to be of limited value.

This reverts commit a39a2431c1.
 2008-09-03 17:43:30 -07:00
Ben Pfaff bb93ad418c Also disable atexit hooks in fatal_signal_fork(). 
This fixes a problem in ofp-discover, where it would daemonize itself
after setting an IP address on one of its interfaces.  The daemonize
function would call fatal_signal_fork() then exit(0), which would in turn
cause the netdev code to disable the interface and thereby remove the IP
address.

The bug that this fixes was introduced in commit 3cc1ae6a3, "Add ability
to run fatal signal hooks upon normal termination too."

Ben Pfaff 3cc1ae6a32 Add ability to run fatal signal hooks upon normal termination too. 
This is convenient since in many cases we want these hooks to run in
both cases.
