Justin Pettit af04b055a7 Revert "Make vconns keep track of their names and include them in log messages." 
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 123301f8b5 Do not send in-band control traffic to the controller. 
This commit prevents the secure channel from sending any traffic to
or from the controller up to the controller over its OpenFlow connection.
Instead, such traffic is always handled completely locally.  This is
what the changes to in-band control up until now have been converging on:
each time, we have reduced the category of traffic that can be sent up
to the controller because we have found that doing so can cause a control
loop.  This change goes all the way.

Ben Pfaff cfc54b8793 Minimal fix for in-band control loop with hub. 
When a hub has two switches and the controller on three of its ports,
control traffic from the controller to switch 1 is seen by switch 2 as
data traffic, and switch 2 sends it up over its OpenFlow connection.  That
control traffic is in turn seen by the switch 1 as data traffic, and so
switch 1 sends it up over its OpenFlow connection.  And so on: this is a
loop.

This commit fixes the situation by not sending up over the OpenFlow
connection traffic to the controller that arrived on the controller's
port, as well as traffic from the controller.

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.

Ben Pfaff 3059085830 Fix test for fcntl return value. 
POSIX only says that -1 is an error; other return values have unspecified
meanings.

Ben Pfaff 23e60ce176 Allow multiple ports on dpctl addif and delif commands, for convenience. 2008-08-26 12:02:59 -07:00
Ben Pfaff e3d722e73b Implement new OpenFlow "switch statistics" feature. 
This should be useful for reporting the status of a switch on its
front-panel display (for those switches that have one) or in the
controller UI.

Ben Pfaff b057b10a74 rconn: Add functions for reporting connection statistics. 2008-08-26 11:51:17 -07:00
Ben Pfaff 3e464f2c68 Add functions for reporting dhcp client statistics. 2008-08-26 11:51:17 -07:00
Ben Pfaff 16c4a745d7 Change netdev_get_in4() to re-check the IP address on each call. 
As part of implementing switch stats, secchan wants to report the
IP address currently configured on an interface.  Caching it for
all time defeats that purpose.

Ben Pfaff 12e6e0e2dd New functions ds_truncate(), ds_last(). 2008-08-26 11:51:17 -07:00
Ben Pfaff 0415ee1ac9 New function ds_put_printable(). 
Use the function in dhcp_option_to_string().

Justin Pettit f1c6daebf3 Send PORT_STATUS messages on port and link changes. Add ability to remotely enable and disable a port through the PORT_MOD message. 2008-08-22 12:47:54 -07:00
Ben Pfaff 8f133305af rconn: Fix bug #100, "Inactivity time-out slow under heavy load." 
The timeout() function returns a duration relative to the time at which the
current state was entered, but rconn_run_wait() was treating it as the
waiting time remaining.

Ben Pfaff 95eb308262 Un-learn the port on which a MAC is located after some time. 
Otherwise, we can send frames the wrong port indefinitely, if the device
in question does not itself initiate sending data.

Justin Pettit 829f7d3961 Link to the normal OpenFlow lib directory, not this hidden one. 2008-08-18 22:13:36 -07:00
Ben Pfaff 15938f6d22 Don't compare wildcards, nw_src_mask, nw_dst_mask fields in hash table. 
They should always compare equal, so there's no point in wasting the
time.

Justin Pettit a71357e8f7 Fix dump-flows to be usable by add-flows. 
Some of the fields when printing a flow are hex, but they don't have a
preceeding "0x".  When one tries to import them, they're treated as decimal
and weird results occur.  Bug 27.
