netdev: Fix carrier status for down interfaces.

2010-11-16T23:17:38+00:00

Currently netdev_get_carrier() returns both a carrier status and
an error code.  However, usage of the error code was inconsistent:
most callers either ignored it or didn't perform their task if an
error occured, which prevented bond rebalancing.  This makes the
handling consistent by translating an error into a down status in
the netdev library.

tunneling mechanism in the kernel.

netdev: Don't assume all netdevs are available at runtime.

2010-08-24T20:58:00+00:00

Currently we print a warning if a user tries to configure a
netdev that is not in the list that userspace knows about.
However, it is possible that a given netdev maybe be enabled but
when it tries to create a device it finds out that it can't
(not supported by kernel module, hardware not present, etc.).
This makes the behavior the same in both cases.

vlog: Introduce VLOG_DEFINE_THIS_MODULE for declaring vlog module in use.

2010-07-21T22:47:09+00:00

Adding a macro to define the vlog module in use adds a level of
indirection, which makes it easier to change how the vlog module must be
defined.  A followup commit needs to do that, so getting these widespread
changes out of the way first should make that commit easier to review.

Simplify shash_find() followed by shash_add() into shash_add_once().

This is just a cleanup.

Implement QoS framework.

2010-06-17T22:04:12+00:00

ovs-vswitchd doesn't declare its QoS capabilities in the database yet,
so the controller has to know what they are.  We can add that later.

The linux-htb QoS class has been tested to the extent that I can see that
it sets up the queues I expect when I run "tc qdisc show" and "tc class
show".  I haven't tested that the effects on flows are what we expect them
to be.  I am sure that there will be problems in that area that we will
have to fix.

netdev: Remove may_create/may_open flags.

2010-06-02T00:27:45+00:00

The most recent revision of the netdev library added may_create
and may_open flags to explicitly state the intent of the caller as
to whether the device should already be in use.  This was simply
a sanity check for users of the netdev library and the configuration.
At this point the netdev library and its users are well behaved and
should no longer need to be checked.  Additional checks have also
been added for incorrect configuration that mean the netdev library
is no longer the primary line of defense.

These flags themselves create problems because it is not always
easy for a library to know what the state of devices should be.
This is particularly a problem for ovs-openflowd, which expects
ports to be added by ovs-dpctl.  Fixing this either requires that
the checks are so permissive to be useless or ugly hacks to get
around them.  Since they are no longer needed, just remove the
checks.

This commit restores the previous behavior of ovs-openflowd to
not require that ports be specified on the command line or
cleaned up after use.

lib: Disable Linux-specific libraries on non-Linux systems.

2010-05-26T22:36:58+00:00

patch: Remove veth driver.

2010-05-18T19:57:25+00:00

Now that we have a new patch implementation, remove the veth driver
and its userspace components.  Then rename 'patchnew' to 'patch'.
The new implementation is a drop-in replacement for the old one.
