Our own functions don't seem to work with the latest gcc,
so it seems to make sense to use the glibc versions which
should be equivalent and maintained.
Specifically implemented the ability to match on
the lower 8 bits of the ARP opcode as nw_proto, and
the ARP source and dest protocol addresses as nw_src
and nw_dst respectively.
added a human readable string to ofp_stats_desc to describe
the datapath, e.g., "switch4 in closet 3b of Gates"
* updated openflow.h
* updated udatapath: defaults to "$HOSTNAME pid=$$"
* updated kernel datapath: defaults to "$HOSTNAME idx=$i"
* updated wireshark plugin
* added regression test for ofp_desc_stats
* addressed KK's review comments from:
https://mailman.stanford.edu/pipermail/openflow-dev/2009-December/000545.html
Improve precision of flow duration (time a flow has
been installed in a switch) from seconds to nanoseconds
to improve throughput measurement accuracy when using
flow stats messages. This implementation splits the
existing duration fields into duration_sec and
duration_nsec for both flow expiration and flow stats
messages. Passes included unit tests on Ubuntu 8.04.
Enable ofdatapath to run without slicing.
When the related dependencies are not met,
using the --no-slicing runtime option, ofdatapath
can run without tc backend/frontend support (and
therefore without slicing support).
tap devices do not have any queue configuration.
But we need to set queue_fd[0] which is the default
socket that best-effort traffic goes out.
When this was not set, fd defaulted to 0, which is
stdio, and resulted to print all packets.
Thanks Mikio for spotting the exact problem.
This commit updates the userspace datapath to handle the slicing
mechanism.
-> Keep list of queues per port.
-> Map flows to queues
-> Report queue configuration and statistics
-> Send appropriate error messages
Handle OF venor extensions (experimental). Currently only
for slicing configuration messages.
Slicing configuration messages are typically initiated by
dpctl. After capturing them here, we use the appropriate
functionality from datapath and netdev to change the
underlying queueing configuration.
netdev uses tc to implement the queueing mechanism.
Queue configuration takes place through dpctl.
Each queue is represented by a send-only socket, while
there is a default socket that receives traffic and
sends best-effort traffic. This is necessary to overcome
limitations from user-only implementation.
datapath/udatapath now sends ofp_flow_removed messages instead of
nx_flow_end. This allows for the removal of secchan/flow-end.* as
flow-end message now no longer need to be translated.
When a switch receives a barrier message it must first complete all
commands sent before the barrier message before executing any commands
after it. When all commands before the Barrier message have completed,
it must send a barrier reply message back to the controller.

Add a CHECK_OVERLAP flag to flow mods which requires the switch to do
the (potentially more costly) check that there doesn't already exist a
conflicting flow with the same priority. If there is one, the mod
fails and an error code is returned.

Fix BUG#49: Add OpenFlow protocol statistical information collector
and user interface. This feature use PRIVATE_VENDOR_ID to communicate
betwewn control plane process and user interface. PRIVATE_VENDOR_ID is
defined only for private use (and based on private OUI).
Fix BUG#47: Add simple controller failover to provide control plane
session redundancy.
Improved BUG#47: Add liveliness check of a peer using ECHO exchange
with non-zero XID.
Fix BUG#50: Change minimum configurable value of inactivity-timer for
OpenFlow control plane session to provide quick controller failover.
Change ofprotocol(8) man page to describe failover.
Remove monolithic OpenFlow switch.
Add userspace datapath.
Fix BUG#13: Revise check wildcards for in_port != out_port output
validation.
Fix BUG#30: Made use of get_jiffies_64 instead of jiffies.
Fix BUG#31: Fix NetFPGA crash in case of test_delete test harness run.
Fix BUG#32: Add stack depth limitation to avoid inifinite loop in
log_backtrace.
Fix BUG#33: Improve NetFPGA kernel extension and NetFPGA image to
support MAC address rewrite features (two actions) on NetFPGA enabled
OpenFlow switch.
Fix BUG#34: Add NetFPGA kernel extension source codes to create
distribution package with NetFPGA correctly.
Fix BUG#38: Improve regression test for FLOW_MOD ACTION SET_DL_SRC and
SET_DL_DST.
Fix BUG#39: Correct misunderstanding of byte order ops for OFPAT_XXX.
