Ben Pfaff fac543387f Fix "make dist" in datapath/linux-2.4 when --with-l24 not used. 
This makes the linux-2.4 Makefile.main.in structure much more
similar to the linux-2.6 Makefile.main.in.

Justin Pettit a3479a759d Fixed typos in dummy hardware table example that caused compilation errors. 
This still has a license conflict with GPL-only "call_rcu" function.  We'll figure this out later.  Thanks for pointing it out, Ben!

Ben Pfaff 0b75446a26 Don't try to destroy dp_dev while the local port holds a reference to it. 
Fixes a message output at deldp time:
unregister_netdevice: waiting for of0 to become free. Usage count = 1

Thanks to Murphy and Justin for reporting this bug.

Ben Pfaff 3d8bf698e7 Ignore NLMSG_DONE Netlink messages in dpif. 
Otherwise the secchan considers the NLMSG_DONE at the end of a stats
dump to be an error and disconnects from the netlink connection.

Thanks to Martin for discovering the problem.

Ben Pfaff 711c48de9d Break MAC learning out of controller into library.

 2008-05-28 10:46:54 -07:00
Ben Pfaff 23e054dcb6 New functions for getting and setting network device flags. 
This allows us to open network devices without bringing them up
and setting them for promiscuous mode, which will be useful in the
secchan for in-band communication.
 2008-05-28 10:46:54 -07:00
Ben Pfaff 6b8436f66b Expose device IP addresses through netdev. 
This will be useful for the secure channel later.
 2008-05-28 10:46:54 -07:00
Ben Pfaff 735683ac61 Move netdev from switch to lib. 
This is in preparation for the secure channel wanting to access
network devices.

Ben Pfaff 94ce314ecb Get rid of obsolete, commented-out debugging code in datapath.c. 2008-05-28 09:58:22 -07:00
Ben Pfaff dbcacca77e Demote warning about runt frames to debug message. 
This message is not too useful since there are various legitimate
ways that we can end up with runt frames, e.g. frames that only
ever passed through virtual network devices and never touched a
physical Ethernet.

Ben Pfaff 253d1704aa Always do exact-match on undefined flow fields, so that such flows can be in table-hash. 2008-05-28 09:58:22 -07:00
Ben Pfaff e5ccf3cc8b Don't allow CONFIG_PREEMPT with Linux 2.6.x before 2.6.21, because it's busted. 2008-05-28 09:58:22 -07:00
Ben Pfaff 4f8e1eb539 Fix buggy table-linear iterator function. 
Apparently the linear table iteration had never really been tested,
since most flows go into table-hash.  It didn't work.  This fixes it.
 2008-05-28 09:58:22 -07:00
Ben Pfaff dfdde7a55f Don't ever send frames on OpenFlow devices to the host stack. 
On Linux 2.6 only, we would send frames received on OpenFlow devices to
the host TCP/IP stack if the dest Ethernet address matched the device's
Ethernet address (or under some other conditions).  This caused confusion
when the host stack was configured for forwarding, because received IP
packets would be forwarded to other interfaces with IP addresses even if
the device on which they were received was configured with no IP address.
(This was discovered by Murphy.  Thanks Murphy!)

This change drops this "feature".  A more or less equivalent feature that
may be less prone to confusion and which works on any kernel version will
be added in a future commit via the of%d device.

This also allowed factoring out common code from the bridge hooks.

Justin Pettit 7a1d4f038d Fix problem with identifying SNAP frames when extracting flows. 
The ssap field was being checked twice to see if it was SNAP, when one of the checks should have been dsap.

Justin Pettit d22fc1ef68 IPv6 is not supported in OpenFlow, so don't try to parse it. 2008-05-10 00:27:13 -07:00
Justin Pettit 3cf996b4cd Zero-out invalid fields when extracting a "match" and transforming it into a "flow". 
When the controller wishes to add a flow entry to the switch, it sends a request with a description of matching flows in a "match".  The switch was adding these exactly as described into the flow tables.  However, when packets arrived, all invalid fields (e.g., the TCP/UDP ports in a non-TCP/UDP packet) are set to zero.  If the rule being added by the controller had not set these invalid fields to zero, the packets would never match.  We now zero out these fields when extracing a "match".

root f2faa2f778 When printing flow expired messages, we should end the line with "\n" instead of "n". 2008-05-07 18:20:13 -07:00
