Enable the port stats for a particular port to be requested by
specifying a port number. Can request all port stats by specifying
OFPP_NONE for the port number.
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
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.
send_flow_end was a hold-over from 0.8.x releases. Version 0.9 removed the
datapath-wide send flow mod expire flag and replaced it by a per-flow flag.
This field was used by the NetFlow code to force notification of expires.
Commit 238c5065 (Vlan pcp match: Reorder VLAN priority field...)
changed ofp_match from 36B to 40B, breaking the 8B alignment of a
number of structs. This commit modifies those structs to at least
pass the assertion tests and regression tests.
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.
detection handler for table maintanance
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.
Flow expiry: Record OFPFF_SEND_FLOW_EXP flag in user data path
vendor_stat: This is a patch that add vendor stats primitive and
reorganise the flow creation process. It does not add any
functionality, it just make it easier for us to add our own hooks.
collector
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#45: Add watchdog timer with automatic table flush to prevent
unpredictable packet forwarding in case of datapth communication lost.
Fix BUG#46: Correct IP packet lenght handling.
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.
