|
* To fix the Undefined Behavior issue causing the compiler to incorrectly
|
|
|

user-provided pointer is now set to NULL after the loop (unless it
|
|
|
|
|
exited via "break;")
|

|
* Users of libopenvswitch will need to double-check the use of such loop
|
|
|
|
|
macros before compiling with a new version.
|
|
|
|
|
* Since the change is limited to the definitions within the headers, the
|
|
|
|
|
ABI is not affected.

ovsdb: relay: Add transaction history support.
Even though relays can be scaled to the big number of servers to
handle a lot more clients, lack of transaction history may cause
significant load if clients are re-connecting.
E.g. in case of the upgrade of a large-scale OVN deployment, relays
can be taken down one by one forcing all the clients of one relay to
jump to other ones. And all these clients will download the database
from scratch from a new relay.
Since relay itself supports monitor_cond_since connection to the
main cluster, it receives the last transaction id along with each
update. Since these transaction ids are 'eid's of actual transactions,
they can be used by relay for a transaction history.
Relay may not receive all the transaction ids, because the main cluster
may combine several changes into a single monitor update. However,
all relays will, likely, receive same updates with the same transaction
ids, so the case where transaction id can not be found after
re-connection between relays should not be very common. If some id
is missing on the relay (i.e. this update was merged with some other
update and newer id was used) the client will just re-download the
database as if there was a normal transaction history miss.
OVSDB client synchronization module updated to provide the last
transaction id along with the update. Relay module updated to use
these ids as a transaction id. If ids are zero, relay decides that
the main server doesn't support transaction ids and disables the
transaction history accordingly.
Using ovsdb_txn_replay_commit() instead of ovsdb_txn_propose_commit_block(),
so transactions are added to the history. This can be done, because
relays has no file storage, so there is no need to write anything.
Relay tests modified to test both standalone and clustered database
as a main server. Checks added to ensure that all servers receive the
same transaction ids in monitor updates.

ovsdb: Prepare snapshot JSON in a separate thread.
Conversion of the database data into JSON object, serialization
and destruction of that object are the most heavy operations
during the database compaction. If these operations are moved
to a separate thread, the main thread can continue processing
database requests in the meantime.
With this change, the compaction is split in 3 phases:
1. Initialization:
- Create a copy of the database.
- Remember current database index.
- Start a separate thread to convert a copy of the database
into serialized JSON object.
2. Wait:
- Continue normal operation until compaction thread is done.
- Meanwhile, compaction thread:
* Convert database copy to JSON.
* Serialize resulted JSON.
* Destroy original JSON object.
3. Finish:
- Destroy the database copy.
- Take the snapshot created by the thread.
- Write on disk.
The key for this schema to be fast is the ability to create
a shallow copy of the database. This doesn't take too much
time allowing the thread to do most of work.
Database copy is created and destroyed only by the main thread,
so there is no need for synchronization.
Such solution allows to reduce the time main thread is blocked
by compaction by 80-90%. For example, in ovn-heater tests
with 120 node density-heavy scenario, where compaction normally
takes 5-6 seconds at the end of a test, measured compaction
times was all below 1 second with the change applied. Also,
note that these measured times are the sum of phases 1 and 3,
so actual poll intervals are about half a second in this case.
Only implemented for raft storage for now. The implementation
for standalone databases can be added later by using a file
offset as a database index and copying newly added changes
from the old file to a new one during ovsdb_log_replace().

ovsdb-idl: Support write-only-changed IDL monitor mode.
At a first glance, change tracking should never be allowed for
write-only columns. However, some clients (e.g., ovn-northd) that are
mostly exclusive writers of a database, use change tracking to avoid
duplicating the IDL row records into a local cache when implementing
incremental processing.
The default behavior of the IDL is to automatically turn a write-only
column into a read-write column whenever the client enables change
tracking for that column.
For the afore mentioned clients, this becomes a performance issue.
Commit 1cc618c32524 ("ovsdb-idl: Fix atomicity of writes that don't
change a column's value.") explains why writes that don't change a
column's value cannot be optimized out early if the column is
read/write.
Furthermore, if there is at least one record in any table that
changed during a transaction, then *all* records that have been
written are added to the transaction, even if their values didn't
change. If there are many such rows (e.g., like in ovn-northd's
case) this incurs a significant overhead because:
a. the client has to build this large transaction
b. the transaction has to be sent over the network
c. the server needs to parse this (mostly) no-op update
We now introduce new IDL APIs allowing users to set a new monitoring
mode flag, OVSDB_IDL_WRITE_CHANGED_ONLY, to indicate to the IDL that the
atomicity constraints may be relaxed and written columns that don't
change value can be skipped from the current transaction.
We benchmarked ovn-northd performance when using this new mode
against NB and SB databases taken from ovn-kubernetes scale tests.
We noticed that when a minor change is performed to the Northbound
database (e.g., NB_Global.nb_cfg is incremented) the time it takes to
build the Southbound transaction becomes negligible (vs ~1.5 seconds
before this change).
End-to-end ovn-kubernetes scale tests on 120-node clusters also show
significant reduction of latency to bring up pods; both average and P99
latency decreased by ~30%.

|
netdev-dpdk: Add shared mempool config.
Mempools may currently be shared between DPDK ports based
on port MTU and NUMA. With some hint from the user we can
increase the sharing on MTU and hence reduce memory
consumption in many cases.
For example, a port with MTU 9000, uses a mempool with an
mbuf size based on 9000 MTU. A port with MTU 1500, uses a
different mempool with an mbuf size based on 1500 MTU.
In this case, assuming same NUMA, both these ports could
share the 9000 MTU mempool.
The user must give a hint as order of creation of ports and
setting of MTUs may vary and we need to ensure that upgrades
from older OVS versions do not require more memory.
This scheme can also prevent multiple mempools being created
for cases where a port is added picking up a default MTU and
an appropriate mempool, but later has it's MTU changed to a
different value requiring a different mempool.
Example usage:
$ ovs-vsctl --no-wait set Open_vSwitch . \
other_config:shared-mempool-config=9000,1500:1,6000:1
Port added on NUMA 0:
* MTU 1500, use mempool based on 9000 MTU
* MTU 5000, use mempool based on 9000 MTU
* MTU 9000, use mempool based on 9000 MTU
* MTU 9300, use mempool based on 9300 MTU (existing behaviour)
Port added on NUMA 1:
* MTU 1500, use mempool based on 1500 MTU
* MTU 5000, use mempool based on 6000 MTU
* MTU 9000, use mempool based on 9000 MTU
* MTU 9300, use mempool based on 9300 MTU (existing behaviour)
Default behaviour is unchanged and mempools are still only created
when needed.

---------------------

dpif-netdev: Forwarding optimization for flows with a simple match.
There are cases where users might want simple forwarding or drop rules
for all packets received from a specific port, e.g ::
"in_port=1,actions=2"
"in_port=2,actions=IN_PORT"
"in_port=3,vlan_tci=0x1234/0x1fff,actions=drop"
"in_port=4,actions=push_vlan:0x8100,set_field:4196->vlan_vid,output:3"
There are also cases where complex OpenFlow rules can be simplified
down to datapath flows with very simple match criteria.
In theory, for very simple forwarding, OVS doesn't need to parse
packets at all in order to follow these rules. "Simple match" lookup
optimization is intended to speed up packet forwarding in these cases.
Design:
Due to various implementation constraints userspace datapath has
following flow fields always in exact match (i.e. it's required to
match at least these fields of a packet even if the OF rule doesn't
need that):
- recirc_id
- in_port
- packet_type
- dl_type
- vlan_tci (CFI + VID) - in most cases
- nw_frag - for ip packets
Not all of these fields are related to packet itself. We already
know the current 'recirc_id' and the 'in_port' before starting the
packet processing. It also seems safe to assume that we're working
with Ethernet packets. So, for the simple OF rule we need to match
only on 'dl_type', 'vlan_tci' and 'nw_frag'.
'in_port', 'dl_type', 'nw_frag' and 13 bits of 'vlan_tci' can be
combined in a single 64bit integer (mark) that can be used as a
hash in hash map. We are using only VID and CFI form the 'vlan_tci',
flows that need to match on PCP will not qualify for the optimization.
Workaround for matching on non-existence of vlan updated to match on
CFI and VID only in order to qualify for the optimization. CFI is
always set by OVS if vlan is present in a packet, so there is no need
to match on PCP in this case. 'nw_frag' takes 2 bits of PCP inside
the simple match mark.
New per-PMD flow table 'simple_match_table' introduced to store
simple match flows only. 'dp_netdev_flow_add' adds flow to the
usual 'flow_table' and to the 'simple_match_table' if the flow
meets following constraints:
- 'recirc_id' in flow match is 0.
- 'packet_type' in flow match is Ethernet.
- Flow wildcards contains only minimal set of non-wildcarded fields
(listed above).
If the number of flows for current 'in_port' in a regular 'flow_table'
equals number of flows for current 'in_port' in a 'simple_match_table',
we may use simple match optimization, because all the flows we have
are simple match flows. This means that we only need to parse
'dl_type', 'vlan_tci' and 'nw_frag' to perform packet matching.
Now we make the unique flow mark from the 'in_port', 'dl_type',
'nw_frag' and 'vlan_tci' and looking for it in the 'simple_match_table'.
On successful lookup we don't need to run full 'miniflow_extract()'.
Unsuccessful lookup technically means that we have no suitable flow
in the datapath and upcall will be required. So, in this case EMC and
SMC lookups are disabled. We may optimize this path in the future by
bypassing the dpcls lookup too.
Performance improvement of this solution on a 'simple match' flows
should be comparable with partial HW offloading, because it parses same
packet fields and uses similar flow lookup scheme.
However, unlike partial HW offloading, it works for all port types
including virtual ones.
Performance results when compared to EMC:
Test setup:
virtio-user OVS virtio-user
Testpmd1 ------------> pmd1 ------------> Testpmd2
(txonly) x<------ pmd2 <------------ (mac swap)
Single stream of 64byte packets. Actions:
in_port=vhost0,actions=vhost1

Stats collected from pmd1 and pmd2, so there are 2 scenarios:
Virt-to-Virt : Testpmd1 ------> pmd1 ------> Testpmd2.
Virt-to-NoCopy : Testpmd2 ------> pmd2 --->x Testpmd1.
Here the packet sent from pmd2 to Testpmd1 is always dropped, because
the virtqueue is full since Testpmd1 is in txonly mode and doesn't
receive any packets. This should be closer to the performance of a
VM-to-Phy scenario.
Test performed on machine with Intel Xeon CPU E5-2690 v4 @ 2.60GHz.
Table below represents improvement in throughput when compared to EMC.
+----------------+------------------------+------------------------+
| | Default (-g -O2) | "-Ofast -march=native" |
| Scenario +------------+-----------+------------+-----------+
| | GCC | Clang | GCC | Clang |
+----------------+------------+-----------+------------+-----------+
| Virt-to-Virt | +18.9% | +25.5% | +10.8% | +16.7% |
| Virt-to-NoCopy | +24.3% | +33.7% | +14.9% | +22.0% |
+----------------+------------+-----------+------------+-----------+
For Phy-to-Phy case performance improvement should be even higher, but
it's not the main use-case for this functionality. Performance
difference for the non-simple flows is within a margin of error.

dpdk: Remove default values for socket-mem and limit.
This change removes the default values for EAL args socket-mem and
socket-limit. As DPDK supports dynamic memory allocation, there is no
need to allocate a certain amount of memory on start-up, nor limit the
amount of memory available, if not requested.
Currently, socket-mem has a default value of 1024 when it is not
configured by the user, and socket-limit takes on the value of
socket-mem, 1024, by default. With this change, socket-mem is not
configured by default, meaning that socket-limit is not either.
Neither, either or both options can be set.
Removed extra logs that announce this change and fixed documentation.

dpdk: Support running PMD threads on any core.
Previously in OVS, a PMD thread running on cpu X used lcore X.
This assumption limited OVS to run PMD threads on physical cpu <
RTE_MAX_LCORE.
DPDK 20.08 introduced a new API that associates a non-EAL thread to a free
lcore. This new API does not change the thread characteristics (like CPU
affinity) and let OVS run its PMD threads on any cpu regardless of
RTE_MAX_LCORE.
The DPDK multiprocess feature is not compatible with this new API and is
disabled.
DPDK still limits the number of lcores to RTE_MAX_LCORE (128 on x86_64)
which should be enough for OVS pmd threads (hopefully).
DPDK lcore/OVS pmd threads mapping are logged at threads when trying to
attach a OVS PMD thread, and when detaching.
A new command is added to help get DPDK point of view of the DPDK lcores
at any time:
$ ovs-appctl dpdk/lcore-list
lcore 0, socket 0, role RTE, cpuset 0
lcore 1, socket 0, role NON_EAL, cpuset 1
lcore 2, socket 0, role NON_EAL, cpuset 15

dpif-netdev: Expand the meter capacity.
For now, ovs-vswitchd use the array of the dp_meter struct
to store meter's data, and at most, there are only 65536
(defined by MAX_METERS) meters that can be used. But in some
case, for example, in the edge gateway, we should use 200,000+,
at least, meters for IP address bandwidth limitation.
Every one IP address will use two meters for its rx and tx
path[1]. In other way, ovs-vswitchd should support meter-offload
(rte_mtr_xxx api introduced by dpdk.), but there are more than
65536 meters in the hardware, such as Mellanox ConnectX-6.
This patch use cmap to manage the meter, instead of the array.
* Insertion performance, ovs-ofctl add-meter 1000+ meters,
the cmap takes about 4000ms, as same as previous implementation.
* Lookup performance in datapath, we add 1000+ meters which rate limit
are 10Gbps (the NIC cards are 10Gbps, so netdev-datapath will not
drop the packets.), and a flow which only forward packets from p0
to p1, with meter action[2]. On other machine, pktgen-dpdk will
generate 64B packets to p0.
The forwarding performance always is 1324 Kpps on my server
which CPU is Intel E5-2650, 2.00GHz.

ovs-numa: Support non-contiguous numa nodes and offline CPU cores.
This change removes the assumption that numa nodes and cores are numbered
contiguously in linux. This change is required to support some Power
systems.
A check has been added to verify that cores are online,
offline cores result in non-contiguously numbered cores.
DPDK EAL option generation is updated to work with non-contiguous numa nodes.
These options can be seen in the ovs-vswitchd.log. For example:
a system containing only numa nodes 0 and 8 will generate the following:
EAL ARGS: ovs-vswitchd --socket-mem 1024,0,0,0,0,0,0,0,1024 \
--socket-limit 1024,0,0,0,0,0,0,0,1024 -l 0
Tests for pmd and dpif-netdev have been updated to validate non-contiguous
numbered nodes.

conntrack: Handle SNAT with all-zero IP address.
This patch introduces for the userspace datapath the handling
of rules like the following:
ct(commit,nat(src=0.0.0.0),...)
Kernel datapath already handle this case that is particularly
handy in scenarios like the following:
Given A: 10.1.1.1, B: 192.168.2.100, C: 10.1.1.2
A opens a connection toward B on port 80 selecting as source port 10000.
B's IP gets dnat'ed to C's IP (10.1.1.1:10000 -> 192.168.2.100:80).
This will result in:
tcp,orig=(src=10.1.1.1,dst=192.168.2.100,sport=10000,dport=80),
reply=(src=10.1.1.2,dst=10.1.1.1,sport=80,dport=10000),
protoinfo=(state=ESTABLISHED)
A now tries to establish another connection with C using source port
10000, this time using C's IP address (10.1.1.1:10000 -> 10.1.1.2:80).
This second connection, if processed by conntrack with no SNAT/DNAT
involved, collides with the reverse tuple of the first connection,
so the entry for this valid connection doesn't get created.
With this commit, and adding a SNAT rule with 0.0.0.0 for
10.1.1.1:10000 -> 10.1.1.2:80 will allow to create the conn entry:
tcp,orig=(src=10.1.1.1,dst=10.1.1.2,sport=10000,dport=80),
reply=(src=10.1.1.2,dst=10.1.1.1,sport=80,dport=10001),
protoinfo=(state=ESTABLISHED)
tcp,orig=(src=10.1.1.1,dst=192.168.2.100,sport=10000,dport=80),
reply=(src=10.1.1.2,dst=10.1.1.1,sport=80,dport=10000),
protoinfo=(state=ESTABLISHED)
The issue exists even in the opposite case (with A trying to connect
to C using B's IP after establishing a direct connection from A to C).
This commit refactors the relevant function in a way that both of the
previously mentioned cases are handled as well.

dpif-netdev/dpcls-avx512: Enable 16 block processing.
This commit implements larger subtable searches in avx512. A limitation
of the previous implementation was that up to 8 blocks of miniflow
data could be matched on (so a subtable with 8 blocks was handled
in avx, but 9 blocks or more would fall back to scalar/generic).
This limitation is removed in this patch, where up to 16 blocks
of subtable can be matched on.
From an implementation perspective, the key to enabling 16 blocks
over 8 blocks was to do bitmask calculation up front, and then use
the pre-calculated bitmasks for 2x passes of the "blocks gather"
routine. The bitmasks need to be shifted for k-mask usage in the
upper (8-15) block range, but it is relatively trivial. This also
helps in case expanding to 24 blocks is desired in future.
The implementation of the 2nd iteration to handle > 8 blocks is
behind a conditional branch which checks the total number of bits.
This helps the specialized versions of the function that have a
miniflow fingerprint of less-than-or-equal 8 blocks, as the code
can be statically stripped out of those functions. Specialized
functions that do require more than 8 blocks will have the branch
removed and unconditionally execute the 2nd blocks gather routine.
Lastly, the _any() flavour will have the conditional branch, and
the branch predictor may mispredict a bit, but per burst will
likely get most packets correct (particularly towards the middle
and end of a burst).
The code has been run with unit tests under autovalidation and
passes all cases, and unit test coverage has been checked to
ensure the 16 block code paths are executing.

ofproto-dpif: APIs and CLI option to add/delete static fdb entry.
Currently there is an option to add/flush/show ARP/ND neighbor. This
covers L3 side. For L2 side, there is only fdb show command. This
commit gives an option to add/del an fdb entry via ovs-appctl.
CLI command looks like:
To add:
ovs-appctl fdb/add <bridge> <port> <vlan> <Mac>
ovs-appctl fdb/add br0 p1 0 50:54:00:00:00:05
To del:
ovs-appctl fdb/del <bridge> <vlan> <Mac>
ovs-appctl fdb/del br0 0 50:54:00:00:00:05
Added two new APIs to provide convenient interface to add and delete
static-macs.
bool xlate_add_static_mac_entry(const struct ofproto_dpif *,
ofp_port_t in_port,
struct eth_addr dl_src, int vlan);
bool xlate_delete_static_mac_entry(const struct ofproto_dpif *,
struct eth_addr dl_src, int vlan);
1. Static entry should not age. To indicate that entry being
programmed is a static entry, 'expires' field in 'struct mac_entry'
will be set to a MAC_ENTRY_AGE_STATIC_ENTRY. A check for this value
is made while deleting mac entry as part of regular aging process.
2. Another change to the mac-update logic, when a packet with same
dl_src as that of a static-mac entry arrives on any port, the logic
will not modify the expires field.
3. While flushing fdb entries, made sure static ones are not evicted.
4. Updated "ovs-appctl fdb/stats-show br0" to display number of static
entries in switch
Added following tests:
ofproto-dpif - static-mac add/del/flush
ofproto-dpif - static-mac mac moves

dpif-netlink: Introduce per-cpu upcall dispatch.
The Open vSwitch kernel module uses the upcall mechanism to send
packets from kernel space to user space when it misses in the kernel
space flow table. The upcall sends packets via a Netlink socket.
Currently, a Netlink socket is created for every vport. In this way,
there is a 1:1 mapping between a vport and a Netlink socket.
When a packet is received by a vport, if it needs to be sent to
user space, it is sent via the corresponding Netlink socket.
This mechanism, with various iterations of the corresponding user
space code, has seen some limitations and issues:
* On systems with a large number of vports, there is correspondingly
a large number of Netlink sockets which can limit scaling.
(https://bugzilla.redhat.com/show_bug.cgi?id=1526306)
* Packet reordering on upcalls.
(https://bugzilla.redhat.com/show_bug.cgi?id=1844576)
* A thundering herd issue.
(https://bugzilla.redhat.com/show_bug.cgi?id=1834444)
This patch introduces an alternative, feature-negotiated, upcall
mode using a per-cpu dispatch rather than a per-vport dispatch.
In this mode, the Netlink socket to be used for the upcall is
selected based on the CPU of the thread that is executing the upcall.
In this way, it resolves the issues above as:
a) The number of Netlink sockets scales with the number of CPUs
rather than the number of vports.
b) Ordering per-flow is maintained as packets are distributed to
CPUs based on mechanisms such as RSS and flows are distributed
to a single user space thread.
c) Packets from a flow can only wake up one user space thread.

- OVSDB:

ovsdb: Use column diffs for ovsdb and raft log entries.
Currently, ovsdb-server stores complete value for the column in a database
file and in a raft log in case this column changed. This means that
transaction that adds, for example, one new acl to a port group creates
a log entry with all UUIDs of all existing acls + one new. Same for
ports in logical switches and routers and more other columns with sets
in Northbound DB.
There could be thousands of acls in one port group or thousands of ports
in a single logical switch. And the typical use case is to add one new
if we're starting a new service/VM/container or adding one new node in a
kubernetes or OpenStack cluster. This generates huge amount of traffic
within ovsdb raft cluster, grows overall memory consumption and hurts
performance since all these UUIDs are parsed and formatted to/from json
several times and stored on disks. And more values we have in a set -
more space a single log entry will occupy and more time it will take to
process by ovsdb-server cluster members.
Simple test:
1. Start OVN sandbox with clustered DBs:
# make sandbox SANDBOXFLAGS='--nbdb-model=clustered --sbdb-model=clustered'
2. Run a script that creates one port group and adds 4000 acls into it:
# cat ../memory-test.sh
pg_name=my_port_group
export OVN_NB_DAEMON=$(ovn-nbctl --pidfile --detach --log-file -vsocket_util:off)
ovn-nbctl pg-add $pg_name
for i in $(seq 1 4000); do
echo "Iteration: $i"
ovn-nbctl --log acl-add $pg_name from-lport $i udp drop
done
ovn-nbctl acl-del $pg_name
ovn-nbctl pg-del $pg_name
ovs-appctl -t $(pwd)/sandbox/nb1 memory/show
ovn-appctl -t ovn-nbctl exit
---
4. Check the current memory consumption of ovsdb-server processes and
space occupied by database files:
# ls sandbox/[ns]b*.db -alh
# ps -eo vsz,rss,comm,cmd | egrep '=[ns]b[123].pid'
Test results with current ovsdb log format:
On-disk Nb DB size : ~369 MB
RSS of Nb ovsdb-servers: ~2.7 GB
Time to finish the test: ~2m
In order to mitigate memory consumption issues and reduce computational
load on ovsdb-servers let's store diff between old and new values
instead. This will make size of each log entry that adds single acl to
port group (or port to logical switch or anything else like that) very
small and independent from the number of already existing acls (ports,
etc.).
Added a new marker '_is_diff' into a file transaction to specify that
this transaction contains diffs instead of replacements for the existing
data.
One side effect is that this change will actually increase the size of
file transaction that removes more than a half of entries from the set,
because diff will be larger than the resulted new value. However, such
operations are rare.
Test results with change applied:
On-disk Nb DB size : ~2.7 MB ---> reduced by 99%
RSS of Nb ovsdb-servers: ~580 MB ---> reduced by 78%
Time to finish the test: ~1m27s ---> reduced by 27%
After this change new ovsdb-server is still able to read old databases,
but old ovsdb-server will not be able to read new ones.
Since new servers could join ovsdb cluster dynamically it's hard to
implement any runtime mechanism to handle cases where different
versions of ovsdb-server joins the cluster. However we still need to
handle cluster upgrades. For this case added special command line
argument to disable new functionality. Documentation updated with the
recommended way to upgrade the ovsdb cluster.

ovsdb-server: Reclaim heap memory after compaction.
Compaction happens at most once in 10 minutes. That is a big time
interval for a heavy loaded ovsdb-server in cluster mode.
In 10 minutes raft logs could grow up to tens of thousands of entries
with tens of gigabytes in total size.
While compaction cleans up raft log entries, the memory in many cases
is not returned to the system, but kept in the heap of running
ovsdb-server process, and it could stay in this condition for a really
long time. In the end one performance spike could lead to a fast
growth of the raft log and this memory will never (for a really long
time) be released to the system even if the database if empty.
Simple example how to reproduce with OVN sandbox:
1. make sandbox SANDBOXFLAGS='--nbdb-model=clustered --sbdb-model=clustered'
2. Run following script that creates 1 port group, adds 4000 acls and
removes all of that in the end:
# cat ../memory-test.sh
pg_name=my_port_group
export OVN_NB_DAEMON=$(ovn-nbctl --pidfile --detach --log-file -vsocket_util:off)
ovn-nbctl pg-add $pg_name
for i in $(seq 1 4000); do
echo "Iteration: $i"
ovn-nbctl --log acl-add $pg_name from-lport $i udp drop
done
ovn-nbctl acl-del $pg_name
ovn-nbctl pg-del $pg_name
ovs-appctl -t $(pwd)/sandbox/nb1 memory/show
ovn-appctl -t ovn-nbctl exit
---
3. Stopping one of Northbound DB servers:
ovs-appctl -t $(pwd)/sandbox/nb1 exit
Make sure that ovsdb-server didn't compact the database before
it was stopped. Now we have a db file on disk that contains
4000 fairly big transactions inside.
4. Trying to start same ovsdb-server with this file.
# cd sandbox && ovsdb-server <...> nb1.db
At this point ovsdb-server reads all the transactions from db
file and performs all of them as fast as it can one by one.
When it finishes this, raft log contains 4000 entries and
ovsdb-server consumes (on my system) ~13GB of memory while
database is empty. And libc will likely never return this memory
back to system, or, at least, will hold it for a really long time.
This patch adds a new command 'ovsdb-server/memory-trim-on-compaction'.
It's disabled by default, but once enabled, ovsdb-server will call
'malloc_trim(0)' after every successful compaction to try to return
unused heap memory back to system. This is glibc-specific, so we
need to detect function availability in a build time.
Disabled by default since it adds from 1% to 30% (depending on the
current state) to the snapshot creation time and, also, next memory
allocations will likely require requests to kernel and that might be
slower. Could be enabled by default later if considered broadly
beneficial.

dpctl: Add add/mod/del-flows command.
When you would like to add, modify, or delete a lot of flows in the
datapath, for example when you want to measure performance, adding
one flow at the time won't scale. This as it takes a decent amount
of time to set up the datapath connection.
This new command is in-line with the same command available in
ovs-ofctl which allows the same thing, with the only difference that
we do not verify all lines before we start execution. This allows for
a continuous add/delete stream. For example with a command like this:
python3 -c 'while True:
for i in range(0, 1000):
print("add in_port(0),eth(),eth_type(0x800),ipv4(src=100.1.{}.{}) 1".format(int(i / 256), i % 256))
for i in range(0, 1000):
print("delete in_port(0),eth(),eth_type(0x800),ipv4(src=100.1.{}.{})".format(int(i / 256), i % 256))' \

ofp-actions: Add delete field action
This patch adds a new OpenFlow action, delete field, to delete a
field in packets. Currently, only the tun_metadata fields are
supported.
One use case to add this action is to support multiple versions
of geneve tunnel metadatas to be exchanged among different versions
of networks. For example, we may introduce tun_metadata2 to
replace old tun_metadata1, but still want to provide backward
compatibility to the older release. In this case, in the new
OpenFlow pipeline, we would like to support the case to receive a
packet with tun_metadata1, do some processing. And if the packet
is going to a switch in the newer release, we would like to delete
the value in tun_metadata1 and set a value into tun_metadata2.
Currently, ovs does not provide an action to remove a value in
tun_metadata if the value is present. This patch fulfills the gap
by adding the delete_field action. For example, the OpenFlow
syntax to delete tun_metadata1 is:
actions=delete_field:tun_metadata1

dpdk: Add commands to configure log levels.
Enabling debug logs in dpdk can be a challenge to be sure of what is
actually enabled, add commands to list and change those log levels.
However, these commands do not help when tracking issues in dpdk init
itself: dump log levels right after init.
Example:
$ ovs-appctl dpdk/log-list
global log level is debug
id 0: lib.eal, level is info
id 1: lib.malloc, level is info
id 2: lib.ring, level is info
id 3: lib.mempool, level is info
id 4: lib.timer, level is info
id 5: pmd, level is info
[...]
id 37: pmd.net.bnxt.driver, level is notice
id 38: pmd.net.e1000.init, level is notice
id 39: pmd.net.e1000.driver, level is notice
id 40: pmd.net.enic, level is info
[...]
$ ovs-appctl dpdk/log-set debug pmd.*:notice
$ ovs-appctl dpdk/log-list
global log level is debug
id 0: lib.eal, level is debug
id 1: lib.malloc, level is debug
id 2: lib.ring, level is debug
id 3: lib.mempool, level is debug

[...]

userspace: Avoid dp_hash recirculation for balance-tcp bond mode.
Problem:
In OVS, flows with output over a bond interface of type “balance-tcp”
gets translated by the ofproto layer into "HASH" and "RECIRC" datapath
actions. After recirculation, the packet is forwarded to the bond
member port based on 8-bits of the datapath hash value computed through
dp_hash. This causes performance degradation in the following ways:
1. The recirculation of the packet implies another lookup of the
packet’s flow key in the exact match cache (EMC) and potentially
Megaflow classifier (DPCLS). This is the biggest cost factor.
2. The recirculated packets have a new “RSS” hash and compete with the
original packets for the scarce number of EMC slots. This implies more
EMC misses and potentially EMC thrashing causing costly DPCLS lookups.
3. The 256 extra megaflow entries per bond for dp_hash bond selection
put additional load on the revalidation threads.
Owing to this performance degradation, deployments stick to “balance-slb”
bond mode even though it does not do active-active load balancing for
VXLAN- and GRE-tunnelled traffic because all tunnel packet have the
same source MAC address.
Proposed optimization:
This proposal introduces a new load-balancing output action instead of
recirculation.
Maintain one table per-bond (could just be an array of uint16's) and
program it the same way internal flows are created today for each
possible hash value (256 entries) from ofproto layer. Use this table to
load-balance flows as part of output action processing.
Currently xlate_normal() -> output_normal() ->
bond_update_post_recirc_rules() -> bond_may_recirc() and
compose_output_action__() generate 'dp_hash(hash_l4(0))' and
'recirc(<RecircID>)' actions. In this case the RecircID identifies the
bond. For the recirculated packets the ofproto layer installs megaflow
entries that match on RecircID and masked dp_hash and send them to the
corresponding output port.
Instead, we will now generate action as
'lb_output(<bond id>)'
This combines hash computation (only if needed, else re-use RSS hash)
and inline load-balancing over the bond. This action is used *only* for
balance-tcp bonds in userspace datapath (the OVS kernel datapath
remains unchanged).
Example:
Current scheme:
With 8 UDP flows (with random UDP src port):
flow-dump from pmd on cpu core: 2
recirc_id(0),in_port(7),<...> actions:hash(hash_l4(0)),recirc(0x1)
recirc_id(0x1),dp_hash(0xf8e02b7e/0xff),<...> actions:2
recirc_id(0x1),dp_hash(0xb236c260/0xff),<...> actions:1
recirc_id(0x1),dp_hash(0x7d89eb18/0xff),<...> actions:1
recirc_id(0x1),dp_hash(0xa78d75df/0xff),<...> actions:2
recirc_id(0x1),dp_hash(0xb58d846f/0xff),<...> actions:2
recirc_id(0x1),dp_hash(0x24534406/0xff),<...> actions:1
recirc_id(0x1),dp_hash(0x3cf32550/0xff),<...> actions:1
New scheme:
We can do with a single flow entry (for any number of new flows):
in_port(7),<...> actions:lb_output(1)
A new CLI has been added to dump datapath bond cache as given below.
# ovs-appctl dpif-netdev/bond-show [dp]
Bond cache:
bond-id 1 :
bucket 0 - slave 2
bucket 1 - slave 1
bucket 2 - slave 2
bucket 3 - slave 1

bond: Add 'primary' interface concept for active-backup mode.
In AB bonding, if the current active slave becomes disabled, a
replacement slave is arbitrarily picked from the remaining set of
enabled slaves. This commit adds the concept of a "primary" slave: an
interface that will always be (or become) the current active slave if
it is enabled.
The rationale for this functionality is to allow the designation of a
preferred interface for a given bond. For example:
1. Bond is created with interfaces p1 (primary) and p2, both enabled.
2. p1 becomes the current active slave (because it was designated as
the primary).
3. Later, p1 fails/becomes disabled.
4. p2 is chosen to become the current active slave.
5. Later, p1 becomes re-enabled.
6. p1 is chosen to become the current active slave (because it was
designated as the primary)
Note that p1 becomes the active slave once it becomes re-enabled, even
if nothing has happened to p2.
This "primary" concept exists in Linux kernel network interface
bonding, but did not previously exist in OVS bonding.
Only one primary slave interface is supported per bond, and is only
supported for active/backup bonding.
The primary slave interface is designated via
"other_config:bond-primary" when creating a bond.
Also, while adding tests for the "primary" concept, make a few small
improvements to the non-primary AB bonding test.

netdev-offload-tc: Allow to match the IP and port mask of tunnel
This patch allows users to offload the TC flower rules with
tunnel mask. This patch allows masked match of the following,
where previously supported an exact match was supported:
* Remote (dst) tunnel endpoint address
* Local (src) tunnel endpoint address
* Remote (dst) tunnel endpoint UDP port
And also allows masked match of the following, where previously
no match was supported:
* Local (src) tunnel endpoint UDP port
In some case, mask is useful as wildcards. For example, DDOS,
in that case, we don’t want to allow specified hosts IPs or
only source Ports to access the targeted host. For example:
$ ovs-appctl dpctl/add-flow "tunnel(dst=2.2.2.100,src=2.2.2.0/255.255.255.0,tp_dst=4789),\

netdev-afxdp: Add need_wakeup support.
The patch adds support for using need_wakeup flag in AF_XDP rings.
A new option, use-need-wakeup, is added. When this option is used,
it means that OVS has to explicitly wake up the kernel RX, using poll()
syscall and wake up TX, using sendto() syscall. This feature improves
the performance by avoiding unnecessary sendto syscalls for TX.
For RX, instead of kernel always busy-spinning on fille queue, OVS wakes
up the kernel RX processing when fill queue is replenished.
The need_wakeup feature is merged into Linux kernel bpf-next tee with commit
77cd0d7b3f25 ("xsk: add support for need_wakeup flag in AF_XDP rings") and
OVS enables it by default, if libbpf supports it. If users enable it but
runs in an older version of libbpf, then the need_wakeup feature has no effect,
and a warning message is logged.
For virtual interface, it's better set use-need-wakeup=false, since
the virtual device's AF_XDP xmit is synchronous: the sendto syscall
enters kernel and process the TX packet on tx queue directly.
On Intel Xeon E5-2620 v3 2.4GHz system, performance of physical port
to physical port improves from 6.1Mpps to 7.3Mpps.

dpdk: Limit DPDK memory usage.
Since 18.05 release, DPDK moved to dynamic memory model in which
hugepages could be allocated on demand. At the same time '--socket-mem'
option was re-defined as a size of pre-allocated memory, i.e. memory
that should be allocated at startup and could not be freed.
So, DPDK with a new memory model could allocate more hugepage memory
than specified in '--socket-mem' or '-m' options.
This change adds new configurable 'other_config:dpdk-socket-limit'
which could be used to limit the ammount of memory DPDK could use.
It uses new DPDK option '--socket-limit'.
Ex.:
ovs-vsctl set Open_vSwitch . other_config:dpdk-socket-limit="1024,1024"
Also, in order to preserve old behaviour, if '--socket-limit' is not
specified, it will be defaulted to the amount of memory specified by
'--socket-mem' option, i.e. OVS will not be able to allocate more.
This is needed, for example, to disallow OVS to allocate more memory
than reserved for it by Nova in OpenStack installations.

Add a new OVS action check_pkt_larger
This patch adds a new action 'check_pkt_larger' which checks if the
packet is larger than the given size and stores the result in the
destination register.
Usage: check_pkt_larger(len)->REGISTER
Eg. match=...,actions=check_pkt_larger(1442)->NXM_NX_REG0[0],next;
This patch makes use of the new datapath action - 'check_pkt_len'
which was recently added in the commit [1].
At the start of ovs-vswitchd, datapath is probed for this action.
If the datapath action is present, then 'check_pkt_larger'
makes use of this datapath action.
Datapath action 'check_pkt_len' takes these nlattrs
* OVS_CHECK_PKT_LEN_ATTR_PKT_LEN - 'pkt_len' to check for
* OVS_CHECK_PKT_LEN_ATTR_ACTIONS_IF_GREATER (optional) - Nested actions
to apply if the packet length is greater than the specified 'pkt_len'
* OVS_CHECK_PKT_LEN_ATTR_ACTIONS_IF_LESS_EQUAL (optional) - Nested
actions to apply if the packet length is lesser or equal to the
specified 'pkt_len'.
Let's say we have these flows added to an OVS bridge br-int
table=0, priority=100 in_port=1,ip,actions=check_pkt_larger:100->NXM_NX_REG0[0],resubmit(,1)
table=1, priority=200,in_port=1,ip,reg0=0x1/0x1 actions=output:3
table=1, priority=100,in_port=1,ip,actions=output:4
Then the action 'check_pkt_larger' will be translated as
- check_pkt_len(size=100,gt(3),le(4))
datapath will check the packet length and if the packet length is greater than 100,
it will output to port 3, else it will output to port 4.
In case, datapath doesn't support 'check_pkt_len' action, the OVS action
'check_pkt_larger' sets SLOW_ACTION so that datapath flow is not added.
This OVS action is intended to be used by OVN to check the packet length
and generate an ICMP packet with type 3, code 4 and next hop mtu
in the logical router pipeline if the MTU of the physical interface
is lesser than the packet length. More information can be found here [2]

Add a new OVS action check_pkt_larger
This patch adds a new action 'check_pkt_larger' which checks if the
packet is larger than the given size and stores the result in the
destination register.
Usage: check_pkt_larger(len)->REGISTER
Eg. match=...,actions=check_pkt_larger(1442)->NXM_NX_REG0[0],next;
This patch makes use of the new datapath action - 'check_pkt_len'
which was recently added in the commit [1].
At the start of ovs-vswitchd, datapath is probed for this action.
If the datapath action is present, then 'check_pkt_larger'
makes use of this datapath action.
Datapath action 'check_pkt_len' takes these nlattrs
* OVS_CHECK_PKT_LEN_ATTR_PKT_LEN - 'pkt_len' to check for
* OVS_CHECK_PKT_LEN_ATTR_ACTIONS_IF_GREATER (optional) - Nested actions
to apply if the packet length is greater than the specified 'pkt_len'
* OVS_CHECK_PKT_LEN_ATTR_ACTIONS_IF_LESS_EQUAL (optional) - Nested
actions to apply if the packet length is lesser or equal to the
specified 'pkt_len'.
Let's say we have these flows added to an OVS bridge br-int
table=0, priority=100 in_port=1,ip,actions=check_pkt_larger:100->NXM_NX_REG0[0],resubmit(,1)
table=1, priority=200,in_port=1,ip,reg0=0x1/0x1 actions=output:3
table=1, priority=100,in_port=1,ip,actions=output:4
Then the action 'check_pkt_larger' will be translated as
- check_pkt_len(size=100,gt(3),le(4))
datapath will check the packet length and if the packet length is greater than 100,
it will output to port 3, else it will output to port 4.
In case, datapath doesn't support 'check_pkt_len' action, the OVS action
'check_pkt_larger' sets SLOW_ACTION so that datapath flow is not added.
This OVS action is intended to be used by OVN to check the packet length
and generate an ICMP packet with type 3, code 4 and next hop mtu
in the logical router pipeline if the MTU of the physical interface
is lesser than the packet length. More information can be found here [2]

dpif-netdev: Add specialized generic scalar functions
This commit adds a number of specialized functions, that handle
common miniflow fingerprints. This enables compiler optimization,
resulting in higher performance. Below a quick description of
how this optimization actually works;
"Specialized functions" are "instances" of the generic implementation,
but the compiler is given extra context when compiling. In the case of
iterating miniflow datastructures, the most interesting value to enable
compile time optimizations is the loop trip count per unit.
In order to create a specialized function, there is a generic implementation,
which uses a for() loop without the compiler knowing the loop trip count at
compile time. The loop trip count is passed in as an argument to the function:
uint32_t miniflow_impl_generic(struct miniflow *mf, uint32_t loop_count)
{
for(uint32_t i = 0; i < loop_count; i++)
// do work
}
In order to "specialize" the function, we call the generic implementation
with hard-coded numbers - these are compile time constants!
uint32_t miniflow_impl_loop5(struct miniflow *mf, uint32_t loop_count)
{
// use hard coded constant for compile-time constant-propogation
return miniflow_impl_generic(mf, 5);
}
Given the compiler is aware of the loop trip count at compile time,
it can perform an optimization known as "constant propogation". Combined
with inlining of the miniflow_impl_generic() function, the compiler is
now enabled to *compile time* unroll the loop 5x, and produce "flat" code.
The last step to using the specialized functions is to utilize a
function-pointer to choose the specialized (or generic) implementation.
The selection of the function pointer is performed at subtable creation
time, when miniflow fingerprint of the subtable is known. This technique
is known as "multiple dispatch" in some literature, as it uses multiple
items of information (miniflow bit counts) to select the dispatch function.
By pointing the function pointer at the optimized implementation, OvS
benefits from the compile time optimizations at runtime.

ovn: Support a new Logical_Switch_Port.type - 'external'
In the case of OpenStack + OVN, when the VMs are booted on
hypervisors supporting SR-IOV nics, there are no OVS ports
for these VMs. When these VMs sends DHCPv4, DHPCv6 or IPv6
Router Solicitation requests, the local ovn-controller
cannot reply to these packets. OpenStack Neutron dhcp agent
service needs to be run to serve these requests.
With the new logical port type - 'external', OVN itself can
handle these requests avoiding the need to deploy any
external services like neutron dhcp agent.
To make use of this feature, CMS has to
- create a logical port for such VMs
- set the type to 'external'
- create an HA chassis group and associate the logical port
to it or associate an already existing HA chassis group.
- create a localnet port for the logical switch
- configure the ovn-bridge-mappings option in the OVS db.
HA chassis with the highest priority becomes the master of
the HA chassis group and the ovn-controller running in that
'chassis', claims the Port_Binding for that logical port
and it adds the necessary DHCPv4/v6 OF flows. Since the packet
enters the logical switch pipeline via the localnet port,
the inport register (reg14) is set
to the tunnel key of localnet port in the match conditions.
In case the chassis goes down for some reason, next higher
priority HA chassis becomes the master and claims the port.
When the VM with the external port, sends an ARP request for
the router ips, only the chassis which has claimed the port,
will reply to the ARP requests. Rest of the chassis on
receiving these packets drop them in the ingress switch
datapath stage - S_SWITCH_IN_EXTERNAL_PORT which is just
before S_SWITCH_IN_L2_LKUP.
This would guarantee that only the chassis which has claimed
the external ports will run the router datapath pipeline.

revalidator: Rebalance offloaded flows based on the pps rate
This is the third patch in the patch-set to support dynamic rebalancing
of offloaded flows.
The dynamic rebalancing functionality is implemented in this patch. The
ukeys that are not scheduled for deletion are obtained and passed as input
to the rebalancing routine. The rebalancing is done in the context of
revalidation leader thread, after all other revalidator threads are
done with gathering rebalancing data for flows.
For each netdev that is in OOR state, a list of flows - both offloaded
and non-offloaded (pending) - is obtained using the ukeys. For each netdev
that is in OOR state, the flows are grouped and sorted into offloaded and
pending flows. The offloaded flows are sorted in descending order of
pps-rate, while pending flows are sorted in ascending order of pps-rate.
The rebalancing is done in two phases. In the first phase, we try to
offload all pending flows and if that succeeds, the OOR state on the device
is cleared. If some (or none) of the pending flows could not be offloaded,
then we start replacing an offloaded flow that has a lower pps-rate than
a pending flow, until there are no more pending flows with a higher rate
than an offloaded flow. The flows that are replaced from the device are
added into kernel datapath.
A new OVS configuration parameter "offload-rebalance", is added to ovsdb.
The default value of this is "false". To enable this feature, set the
value of this parameter to "true", which provides packets-per-second
rate based policy to dynamically offload and un-offload flows.
Note: This option can be enabled only when 'hw-offload' policy is enabled.
It also requires 'tc-policy' to be set to 'skip_sw'; otherwise, flow
offload errors (specifically ENOSPC error this feature depends on) reported
by an offloaded device are supressed by TC-Flower kernel module.

Support accepting and displaying table names in OVS tools.
OpenFlow has little-known support for naming tables. Open vSwitch has
supported table names for ages, but it has never used or displayed them
outside of commands dedicated to table manipulation. This commit adds
support for table names in ovs-ofctl. When a table has a name, it displays
that name in flows and actions, so that, for example, the following:
table=1, arp, actions=resubmit(,2)
might become:
table=ingress_acl, arp, actions=resubmit(,mac_learning)
given appropriately named tables.
For backward compatibility, only interactive ovs-ofctl commands by default
display table names; to display them in scripts, use the new --names
option.
This feature was inspired by a talk that Kei Nohguchi presented at Open

datapath: conntrack: Support conntrack zone limit
Upstream commit:
commit 11efd5cb04a184eea4f57b68ea63dddd463158d1
Author: Yi-Hung Wei <yihung.wei@gmail.com>

openvswitch: Support conntrack zone limit
Currently, nf_conntrack_max is used to limit the maximum number of
conntrack entries in the conntrack table for every network namespace.
For the VMs and containers that reside in the same namespace,
they share the same conntrack table, and the total # of conntrack entries
for all the VMs and containers are limited by nf_conntrack_max. In this
case, if one of the VM/container abuses the usage the conntrack entries,
it blocks the others from committing valid conntrack entries into the
conntrack table. Even if we can possibly put the VM in different network
namespace, the current nf_conntrack_max configuration is kind of rigid
that we cannot limit different VM/container to have different # conntrack
entries.
To address the aforementioned issue, this patch proposes to have a
fine-grained mechanism that could further limit the # of conntrack entries
per-zone. For example, we can designate different zone to different VM,
and set conntrack limit to each zone. By providing this isolation, a
mis-behaved VM only consumes the conntrack entries in its own zone, and
it will not influence other well-behaved VMs. Moreover, the users can
set various conntrack limit to different zone based on their preference.
The proposed implementation utilizes Netfilter's nf_conncount backend
to count the number of connections in a particular zone. If the number of
connection is above a configured limitation, ovs will return ENOMEM to the
userspace. If userspace does not configure the zone limit, the limit
defaults to zero that is no limitation, which is backward compatible to
the behavior without this patch.
The following high leve APIs are provided to the userspace:
- OVS_CT_LIMIT_CMD_SET:
* set default connection limit for all zones
* set the connection limit for a particular zone
- OVS_CT_LIMIT_CMD_DEL:
* remove the connection limit for a particular zone
- OVS_CT_LIMIT_CMD_GET:
* get the default connection limit for all zones
* get the connection limit for a particular zone

|
netdev-dpdk: vHost IOMMU support
DPDK v17.11 introduces support for the vHost IOMMU feature.
This is a security feature, which restricts the vhost memory
that a virtio device may access.
This feature also enables the vhost REPLY_ACK protocol, the
implementation of which is known to work in newer versions of
QEMU (i.e. v2.10.0), but is buggy in older versions (v2.7.0 -
v2.9.0, inclusive). As such, the feature is disabled by default
in (and should remain so), for the aforementioned older QEMU
verions. Starting with QEMU v2.9.1, vhost-iommu-support can
safely be enabled, even without having an IOMMU device, with
no performance penalty.
This patch adds a new global config option, vhost-iommu-support,
that controls enablement of the vhost IOMMU feature:
ovs-vsctl set Open_vSwitch . other_config:vhost-iommu-support=true
This value defaults to false; to enable IOMMU support, this field
should be set to true when setting other global parameters on init
(such as "dpdk-socket-mem", for example). Changing the value at
runtime is not supported, and requires restarting the vswitch daemon.

OF support and translation of generic encap and decap
This commit adds support for the OpenFlow actions generic encap
and decap (as specified in ONF EXT-382) to the OVS control plane.
CLI syntax for encap action with properties:
encap(<header>)
encap(<header>(<prop>=<value>,<tlv>(<class>,<type>,<value>),...))
For example:
encap(ethernet)
encap(nsh(md_type=1))
encap(nsh(md_type=2,tlv(0x1000,10,0x12345678),tlv(0x2000,20,0xfedcba9876543210)))
CLI syntax for decap action:
decap()
decap(packet_type(ns=<pt_ns>,type=<pt_type>))
For example:
decap()
decap(packet_type(ns=0,type=0xfffe))
decap(packet_type(ns=1,type=0x894f))
The first header supported for encap and decap is "ethernet" to convert
packets between packet_type (1,Ethertype) and (0,0).
This commit also implements a skeleton for the translation of generic
encap and decap actions in ofproto-dpif and adds support to encap and
decap an Ethernet header.
In general translation of encap commits pending actions and then rewrites
struct flow in accordance with the new packet type and header. In the
case of encap(ethernet) it suffices to change the packet type from
(1, Ethertype) to (0,0) and set the dl_type accordingly. A new
pending_encap flag in xlate ctx is set to mark that an corresponding
datapath encap action must be triggered at the next commit. In the
case of encap(ethernet) ofproto generetas a push_eth action.
The general case for translation of decap() is to emit a datapath action
to decap the current outermost header and then recirculate the packet
to reparse the inner headers. In the special case of an Ethernet packet,
decap() just changes the packet type from (0,0) to (1, dl_type) without
a need to recirculate. The emission of the pop_eth action for the
datapath is postponed to the next commit.
Hence encap(ethernet) and decap() on an Ethernet packet are OF octions
that only incur a cost in the dataplane when a modifed packet is
actually committed, e.g. because it is sent out. They can freely be
used for normalizing the packet type in the OF pipeline without
degrading performance.

ovn: Add a case of policy based routing.
OVN currently supports multiple gateway routers (residing on
different chassis) connected to the same logical topology.
When external traffic enters the logical topology, they can enter
from any gateway routers and reach its eventual destination. This
is achieved with proper static routes configured on the gateway
routers.
But when traffic is initiated in the logical space by a logical
port, we do not have a good way to distribute that traffic across
multiple gateway routers.
This commit introduces one particular way to do it. Based on the
source IP address or source IP network of the packet, we can now
jump to a specific gateway router.
This is very useful for a specific use case of Kubernetes.
When traffic is initiated inside a container heading to outside world,
we want to be able to send such traffic outside the gateway router
residing in the same host as that of the container. Since each
host gets a specific subnet, we can use source IP address based
policy routing to decide on the gateway router.
Rationale for using the same routing table for both source and
destination IP address based routing:
Some hardware network vendors support policy routing in a different table
on arbitrary "match". And when a packet enters, if there is a match
in policy based routing table, the default routing table is not
consulted at all. In case of OVN, we mainly want policy based routing
for north-south traffic. We want east-west traffic to flow as-is. Creating
a separate table for policy based routing complicates the configuration
quite a bit. For e.g., if we have a source IP network based rule added,
to decide a particular gateway router as a next hop, we should add rules at
a higher priority for all the connected routes to make sure that east-west
traffic is not effected in the policy based routing table itself.

netdev-dpdk: Enable Rx checksum offloading feature on DPDK physical ports.
Add Rx checksum offloading feature support on DPDK physical ports. By default,
the Rx checksum offloading is enabled if NIC supports. However,
the checksum offloading can be turned OFF either while adding a new DPDK
physical port to OVS or at runtime.
The rx checksum offloading can be turned off by setting the parameter to
'false'. For eg: To disable the rx checksum offloading when adding a port,
'ovs-vsctl add-port br0 dpdk0 -- \
set Interface dpdk0 type=dpdk options:rx-checksum-offload=false'
OR (to disable at run time after port is being added to OVS)
'ovs-vsctl set Interface dpdk0 options:rx-checksum-offload=false'
Similarly to turn ON rx checksum offloading at run time,
'ovs-vsctl set Interface dpdk0 options:rx-checksum-offload=true'
The Tx checksum offloading support is not implemented due to the following
reasons.
1) Checksum offloading and vectorization are mutually exclusive in DPDK poll
mode driver. Vector packet processing is turned OFF when checksum offloading
is enabled which causes significant performance drop at Tx side.
2) Normally, OVS generates checksum for tunnel packets in software at the
'tunnel push' operation, where the tunnel headers are created. However
enabling Tx checksum offloading involves,
*) Mark every packets for tx checksum offloading at 'tunnel_push' and
recirculate.
*) At the time of xmit, validate the same flag and instruct the NIC to do the
checksum calculation. In case NIC doesnt support Tx checksum offloading,
the checksum calculation has to be done in software before sending out the
packets.
No significant performance improvement noticed with Tx checksum offloading
due to the e overhead of additional validations + non vector packet processing.
In some test scenarios, it introduces performance drop too.
Rx checksum offloading still offers 8-9% of improvement on VxLAN tunneling
decapsulation even though the SSE vector Rx function is disabled in DPDK poll
mode driver.

|
* New property-based packet-in message format NXT_PACKET_IN2 with support
|
Implement serializing the state of packet traversal in "continuations".
One purpose of OpenFlow packet-in messages is to allow a controller to
interpose on the path of a packet through the flow tables. If, for
example, the controller needs to modify a packet in some way that the
switch doesn't directly support, the controller should be able to
program the switch to send it the packet, then modify the packet and
send it back to the switch to continue through the flow table.
That's the theory. In practice, this doesn't work with any but the
simplest flow tables. Packet-in messages simply don't include enough
context to allow the flow table traversal to continue. For example:
* Via "resubmit" actions, an Open vSwitch packet can have an
effective "call stack", but a packet-in can't describe it, and
so it would be lost.
* A packet-in can't preserve the stack used by NXAST_PUSH and
NXAST_POP actions.
* A packet-in can't preserve the OpenFlow 1.1+ action set.
* A packet-in can't preserve the state of Open vSwitch mirroring
or connection tracking.
This commit introduces a solution called "continuations". A continuation
is the state of a packet's traversal through OpenFlow flow tables. A
"controller" action with the "pause" flag, which is newly implemented in
this commit, generates a continuation and sends it to the OpenFlow
controller in a packet-in asynchronous message (only NXT_PACKET_IN2
supports continuations, so the controller must configure them with
NXT_SET_PACKET_IN_FORMAT). The controller processes the packet-in,
possibly modifying some of its data, and sends it back to the switch with
an NXT_RESUME request, which causes flow table traversal to continue. In
principle, a single packet can be paused and resumed multiple times.
Another way to look at it is:
- "pause" is an extension of the existing OFPAT_CONTROLLER
action. It sends the packet to the controller, with full
pipeline context (some of which is switch implementation
dependent, and may thus vary from switch to switch).
- A continuation is an extension of OFPT_PACKET_IN, allowing for
implementation dependent metadata.
- NXT_RESUME is an extension of OFPT_PACKET_OUT, with the
semantics that the pipeline processing is continued with the
original translation context from where it was left at the time
it was paused.

ofp-actions: Add truncate action.
The patch adds a new action to support packet truncation. The new action
is formatted as 'output(port=n,max_len=m)', as output to port n, with
packet size being MIN(original_size, m).
One use case is to enable port mirroring to send smaller packets to the
destination port so that only useful packet information is mirrored/copied,
saving some performance overhead of copying entire packet payload. Example
use case is below as well as shown in the testcases:
- Output to port 1 with max_len 100 bytes.
- The output packet size on port 1 will be MIN(original_packet_size, 100).
# ovs-ofctl add-flow br0 'actions=output(port=1,max_len=100)'
- The scope of max_len is limited to output action itself. The following
packet size of output:1 and output:2 will be intact.
# ovs-ofctl add-flow br0 \
'actions=output(port=1,max_len=100),output:1,output:2'
- The Datapath actions shows:
# Datapath actions: trunc(100),1,1,2

ofproto: Add relaxed group_mod command ADD_OR_MOD
This patch adds support for a new Group Mod command OFPGC_ADD_OR_MOD to
OVS for all OpenFlow versions that support groups (OF11 and higher).
The new ADD_OR_MOD creates a group that does not yet exist (like ADD)
and modifies an existing group (like MODIFY).
Rational: In OpenFlow 1.x the Group Mod commands OFPGC_ADD and
OFPGC_MODIFY have strict semantics: ADD fails if the group exists,
while MODIFY fails if the group does not exist. This requires a
controller to exactly know the state of the switch when programming a
group in order not run the risk of getting an OFP Error message in
response. This is hard to achieve and maintain at all times in view of
possible switch and controller restarts or other connection losses
between switch and controller.
Due to the un-acknowledged nature of the Group Mod message programming
groups safely and efficiently at the same time is virtually impossible
as the controller has to either query the existence of the group prior
to each Group Mod message or to insert a Barrier Request/Reply after
every group to be sure that no Error can be received at a later stage
and require a complicated roll-back of any dependent actions taken
between the failed Group Mod and the Error.
In the ovs-ofctl command line the ADD_OR_MOD command is made available
through the new option --may-create in the mod-group command:
$ ovs-ofctl -Oopenflow13 del-groups br-int group_id=100

Known issues:
|
|
|
|
|
- Using openvswitch module in conjunction with upstream Linux tunnels:
|
|
|
|
|
* When using the openvswitch module distributed with OVS against kernel
|
|
|
|
|
versions 4.4 to 4.6, the openvswitch module cannot be loaded or used at
|
|
|
|
|
the same time as "ip_gre".
|
|
|
|
|
- Conntrack FTP ALGs: When using the openvswitch module distributed with
|
|
|
|
|
OVS, particular Linux distribution kernels versions may provide diminished
|
|
|
|
|
functionality. This typically affects active FTP data connections when
|
|
|
|
|
using "actions=ct(alg=ftp),..." in flow tables. Specifically:
|
|
|
|
|
* Centos 7.1 kernels (3.10.0-2xx) kernels are unable to correctly set
|
|
|
|
|
up expectations for FTP data connections in multiple zones,
|
|
|
|
|
eg "actions=ct(zone=1,alg=ftp),ct(zone=2,alg=ftp),...". Executing the
|
|
|
|
|
"ct" action for subsequent data connections may fail to determine that
|
|
|
|
|
the data connection is "related" to an existing connection.
|
|
|
|
|
* Centos 7.2 kernels (3.10.0-3xx) kernels may not establish FTP ALG state
|
|
|
|
|
correctly for NATed connections. As a result, flows that perform NAT,
|
|
|
|
|
eg "actions=ct(nat,ftp=alg,table=1),..." may fail to NAT the packet,
|
|
|
|
|
and will populate the "ct_state=inv" bit in the flow.

Add support for connection tracking.
This patch adds a new action and fields to OVS that allow connection
tracking to be performed. This support works in conjunction with the
Linux kernel support merged into the Linux-4.3 development cycle.
Packets have two possible states with respect to connection tracking:
Untracked packets have not previously passed through the connection
tracker, while tracked packets have previously been through the
connection tracker. For OpenFlow pipeline processing, untracked packets
can become tracked, and they will remain tracked until the end of the
pipeline. Tracked packets cannot become untracked.
Connections can be unknown, uncommitted, or committed. Packets which are
untracked have unknown connection state. To know the connection state,
the packet must become tracked. Uncommitted connections have no
connection state stored about them, so it is only possible for the
connection tracker to identify whether they are a new connection or
whether they are invalid. Committed connections have connection state
stored beyond the lifetime of the packet, which allows later packets in
the same connection to be identified as part of the same established
connection, or related to an existing connection - for instance ICMP
error responses.
The new 'ct' action transitions the packet from "untracked" to
"tracked" by sending this flow through the connection tracker.
The following parameters are supported initally:
- "commit": When commit is executed, the connection moves from
uncommitted state to committed state. This signals that information
about the connection should be stored beyond the lifetime of the
packet within the pipeline. This allows future packets in the same
connection to be recognized as part of the same "established" (est)
connection, as well as identifying packets in the reply (rpl)
direction, or packets related to an existing connection (rel).
- "zone=[u16|NXM]": Perform connection tracking in the zone specified.
Each zone is an independent connection tracking context. When the
"commit" parameter is used, the connection will only be committed in
the specified zone, and not in other zones. This is 0 by default.
- "table=NUMBER": Fork pipeline processing in two. The original instance
of the packet will continue processing the current actions list as an
untracked packet. An additional instance of the packet will be sent to
the connection tracker, which will be re-injected into the OpenFlow
pipeline to resume processing in the specified table, with the
ct_state and other ct match fields set. If the table is not specified,
then the packet is submitted to the connection tracker, but the
pipeline does not fork and the ct match fields are not populated. It
is strongly recommended to specify a table later than the current
table to prevent loops.
When the "table" option is used, the packet that continues processing in
the specified table will have the ct_state populated. The ct_state may
have any of the following flags set:
- Tracked (trk): Connection tracking has occurred.
- Reply (rpl): The flow is in the reply direction.
- Invalid (inv): The connection tracker couldn't identify the connection.
- New (new): This is the beginning of a new connection.
- Established (est): This is part of an already existing connection.
- Related (rel): This connection is related to an existing connection.
For more information, consult the ovs-ofctl(8) man pages.
Below is a simple example flow table to allow outbound TCP traffic from
port 1 and drop traffic from port 2 that was not initiated by port 1:
table=0,priority=1,action=drop
table=0,arp,action=normal
table=0,in_port=1,tcp,ct_state=-trk,action=ct(commit,zone=9),2
table=0,in_port=2,tcp,ct_state=-trk,action=ct(zone=9,table=1)
table=1,in_port=2,ct_state=+trk+est,tcp,action=1
table=1,in_port=2,ct_state=+trk+new,tcp,action=drop
Based on original design by Justin Pettit, contributions from Thomas
Graf and Daniele Di Proietto.

- Add support for connection tracking through the new "ct" action
|
Add connection tracking label support.
This patch adds a new 128-bit metadata field to the connection tracking
interface. When a label is specified as part of the ct action and the
connection is committed, the value is saved with the current connection.
Subsequent ct lookups with the table specified will expose this metadata
as the "ct_label" field in the flow.
For example, to allow new TCP connections from port 1->2 and only allow
established connections from port 2->1, and to associate a label with
those connections:
table=0,priority=1,action=drop
table=0,arp,action=normal
table=0,in_port=1,tcp,action=ct(commit,exec(set_field:1->ct_label)),2
table=0,in_port=2,ct_state=-trk,tcp,action=ct(table=1)
table=1,in_port=2,ct_state=+trk,ct_label=1,tcp,action=1

mac-learning: Implement per-port MAC learning fairness.
In "MAC flooding", an attacker transmits an overwhelming number of frames
with unique Ethernet source address on a switch port. The goal is to
force the switch to evict all useful MAC learning table entries, so that
its behavior degenerates to that of a hub, flooding all traffic. In turn,
that allows an attacker to eavesdrop on the traffic of other hosts attached
to the switch, with all the risks that that entails.
Before this commit, the Open vSwitch "normal" action that implements its
standalone switch behavior (and that can be used by OpenFlow controllers
as well) was vulnerable to MAC flooding attacks. This commit fixes the
problem by implementing per-port fairness for MAC table entries: when
the MAC table is at its maximum size, MAC table eviction always deletes an
entry from the port with the most entries. Thus, MAC entries will never
be evicted from ports with only a few entries if a port with a huge number
of entries exists.
Controllers could introduce their own MAC flooding vulnerabilities into
OVS. For a controller that adds destination MAC based flows to an OpenFlow
flow table as a reaction to "packet-in" events, such a bug, if it exists,
would be in the controller code itself and would need to be fixed in the
controller. For a controller that relies on the Open vSwitch "learn"
action to add destination MAC based flows, Open vSwitch has existing
support for eviction policy similar to that implemented in this commit
through the "groups" column in the Flow_Table table documented in
ovs-vswitchd.conf.db(5); we recommend that users of "learn" not already
familiar with eviction groups to read that documentation.
In addition to implementation of per-port MAC learning fairness,
this commit includes some closely related changes:
- Access to client-provided "port" data in struct mac_entry
is now abstracted through helper functions, which makes it
easier to ensure that the per-port data structures are maintained
consistently.
- The mac_learning_changed() function, which had become trivial,
vestigial, and confusing, was removed. Its functionality was folded
into the new function mac_entry_set_port().
- Many comments were added and improved; there had been a lot of
comment rot in previous versions.

utilities: Add bash command-line completion script.
This patch adds bash command-line completion script for ovs-appctl,
ovs-dpctl, ovs-ofctl and ovsdb-tool command. Right now, the script
can do the following:
- display available completion or complete on unfinished user input
(long option, subcommand, and argument).
- once the subcommand (e.g. ofproto/trace) has been given, the
script will print the subcommand format.
- the script can convert between keywords like 'bridge/port/interface/dp'
and the available record in ovsdb.
The limitations are:
- only support small set of important keywords
(dp, datapath, bridge, switch, port, interface, iface).
- does not support parsing of nested options
(e.g. ovsdb-tool create [db [schema]]).
- does not support expansion on repeatitive argument
(e.g. ovs-dpctl show [dp...]).
- only support matching on long options, and only in the format
(--option [arg], i.e. should not use --option=[arg]).
To use the script, either copy it inside /etc/bash_completion.d/
or manually run it via . ovs-command-compgen.bash.
Also, a unit testsuite is provided as ovs-command-compgen-test.bash.
It is suggested that this test script be run only inside
tutorial/sandbox directory.

v2.3.0 - 14 Aug 2014
|
2014-04-28 14:45:07 -07:00
|
|
|
---------------------
|
Enable OpenFlow 1.0, 1.1, 1.2, and 1.3 by default.
The Open vSwitch software switch now supports all the required features of
OpenFlow 1.0 through 1.3, with one known trivial exception[*]. Enable them
by default in ovs-vswitchd.
For now, ovs-ofctl only enables OpenFlow 1.0 by default. This is
because ovs-ofctl implements command such as "add-flow" as raw
OpenFlow requests, but those requests have subtly different semantics
in different OpenFlow versions. For example:
- In OpenFlow 1.0, a "mod-flow" operation that does not find any
existing flow to modify adds a new flow.
- In OpenFlow 1.1, a "mod-flow" operation that does not find any
existing flow to modify adds a new flow, but only if the
mod-flow did not match on the flow cookie.
- In OpenFlow 1.2 and a later, a "mod-flow" operation never adds a
new flow.
[*] OpenFlow 1.1, but not any earlier or later version of OpenFlow,
requires support for VLANs introduced by Ethertype 0x88a8, but Open
vSwitch does not support this Ethertype.

- Linux kernel datapath now has an exact match cache optimizing the

flow matching process.
|

|
|
|
|
|
number of different masks in the datapath. The kernel datapath
|
|

exact match cache removes the overhead of matching the incoming

ovs-vsctl: Improve error reporting
ovs-vsctl is a command-line interface to the Open vSwitch database,
and as such it just modifies the desired Open vSwitch configuration in
the database. ovs-vswitchd, on the other hand, monitors the database
and implements the actual configuration specified in the database.
This can lead to surprises when the user makes a change to the
database, with ovs-vsctl, that ovs-vswitchd cannot actually
implement. In such a case, the ovs-vsctl command silently succeeds
(because the database was successfully updated) but its desired
effects don't actually take place. One good example of such a change
is attempting to add a port with a misspelled name (e.g. ``ovs-vsctl
add-port br0 fth0'', where fth0 should be eth0); another is creating
a bridge or a port whose name is longer than supported
(e.g. ``ovs-vsctl add-br'' with a 16-character bridge name on
Linux). It can take users a long time to realize the error, because it
requires looking through the ovs-vswitchd log.
The patch improves the situation by checking whether operations that
ovs executes succeed and report an error when
they do not. This patch only report add-br and add-port
operation errors by examining the `ofport' value that
ovs-vswitchd stores into the database record for the newly created
interface. Until ovs-vswitchd finishes implementing the new
configuration, this column is empty, and after it finishes it is
either -1 (on failure) or a positive number (on success).

- ovs-vsctl now reports when ovs-vswitchd fails to create a new port or
|
|
|
|
|

|
2014-04-10 12:50:11 +02:00
|
|
|
- Port creation and configuration errors are now stored in a new error
|
|
|
|
|

|
2014-01-10 15:25:40 -08:00
|
|
|
- The "ovsdbmonitor" graphical tool has been removed, because it was
|
|
|
|
|
poorly maintained and not widely used.
|
2014-02-14 10:34:58 -08:00
|
|
|
- New "check-ryu" Makefile target for running Ryu tests for OpenFlow
|
2014-10-28 11:19:52 +01:00
|
|
|

|
2014-02-19 14:23:39 -08:00
|
|
|
- Added IPFIX support for SCTP flows and templates for ICMPv4/v6 flows.
|
2014-02-20 14:58:36 -08:00
|
|
|
- Upon the receipt of a SIGHUP signal, ovs-vswitchd no longer reopens its

v2.1.0 - 19 Mar 2014
|
2013-08-28 16:18:05 -07:00
|
|
|
---------------------
|
2013-12-11 11:07:01 -08:00
|
|
|
- Address prefix tracking support for flow tables. New columns
|
|
|
|
|
"prefixes" in OVS-DB table "Flow_Table" controls which packet
|
|
|
|
|
header fields are used for address prefix tracking. Prefix
|
|
|
|
|
tracking allows the classifier to skip rules with longer than
|
|
|
|
|
necessary prefixes, resulting in better wildcarding for datapath
|
|
|
|
|
flows. Default configuration is to not use any fields for prefix
|
|
|
|
|
tracking. However, if any flow tables contain both exact matches
|
|
|
|
|
and masked matches for IP address fields, OVS performance may be
|
|
|
|
|
increased by using this feature.
|
|
|
|
|
* As of now, the fields for which prefix lookup can be enabled
|
|
|
|
|
are: 'tun_id', 'tun_src', 'tun_dst', 'nw_src', 'nw_dst' (or
|
|
|
|
|
aliases 'ip_src' and 'ip_dst'), 'ipv6_src', and 'ipv6_dst'.
|
|
|
|
|
(Using this feature for 'tun_id' would only make sense if the
|
|
|
|
|
tunnel IDs have prefix structure similar to IP addresses.)
|
|
|
|
|
* There is a maximum number of fields that can be enabled for any
|
|
|
|
|
one flow table. Currently this limit is 3.
|
|
|
|
|
* Examples:
|
|
|
|
|
$ ovs-vsctl set Bridge br0 flow_tables:0=@N1 -- \
|
|
|
|
|
--id=@N1 create Flow_Table name=table0
|
|
|
|
|
$ ovs-vsctl set Bridge br0 flow_tables:1=@N1 -- \
|
|
|
|
|
--id=@N1 create Flow_Table name=table1
|
|
|
|
|
$ ovs-vsctl set Flow_Table table0 prefixes=ip_dst,ip_src
|
|
|
|
|
$ ovs-vsctl set Flow_Table table1 prefixes=[]
|
2013-11-13 11:19:56 -08:00
|
|
|
- TCP flags matching: OVS now supports matching of TCP flags. This
|
|
|
|
|
has an adverse performance impact when using OVS userspace 1.10
|
|
|
|
|
or older (no megaflows support) together with the new OVS kernel
|
|
|
|
|
module. It is recommended that the kernel and userspace modules
|
|
|
|
|
both are upgraded at the same time.
|
2013-09-23 14:20:27 -07:00
|
|
|
- The default OpenFlow and OVSDB ports will change to
|
|
|
|
|
IANA-assigned numbers in a future release. Consider updating
|
|
|
|
|
your installations to specify port numbers instead of using the
|
|
|
|
|
defaults.
|
2013-10-11 13:23:29 +09:00
|
|
|
- OpenFlow:
|
|
|
|
|
* The OpenFlow 1.1+ "Write-Actions" instruction is now supported.
|
2013-11-06 16:12:34 -08:00
|
|
|
* OVS limits the OpenFlow port numbers it assigns to port 32767 and
|
|
|
|
|
below, leaving port numbers above that range free for assignment
|
|
|
|
|
by the controller.
|
2013-12-11 15:40:52 -08:00
|
|
|
* ovs-vswitchd now honors changes to the "ofport_request" column
|
|
|
|
|
in the Interface table by changing the port's OpenFlow port
|
|
|
|
|
number.
|
2015-02-01 13:50:40 -08:00
|
|
|
* The Open vSwitch software switch now supports OpenFlow groups.
|
2013-10-11 13:17:07 -07:00
|
|
|
- ovs-vswitchd.conf.db.5 man page will contain graphviz/dot

2013-10-14 15:26:40 -07:00
|
|
|
- Support for Linux kernels up to 3.11
|
2013-10-21 14:37:34 -07:00

2013-12-23 10:41:14 -08:00
|
|
|
- ovs-ofctl:
|
|
|
|
|
* New command "ofp-parse-pcap" to dump OpenFlow from PCAP files.
|
2013-10-11 16:24:41 -07:00
|
|
|
- ovs-controller has been renamed test-controller. It is no longer
|
|
|
|
|
packaged or installed by default, because too many users assumed
|
|
|
|
|
incorrectly that ovs-controller was a necessary or desirable part
|
|
|
|
|
of an Open vSwitch deployment.
|
2013-12-05 17:01:30 -08:00
|
|
|
- Added vlog option to export to a UDP syslog sink.
|
2013-03-27 14:26:21 -07:00
|
|
|
- ovsdb-client:
|
|
|
|
|
* The "monitor" command can now monitor all tables in a database,
|
|
|
|
|
instead of being limited to a single table.
|
2013-09-24 13:39:56 -07:00
|
|
|
- The flow-eviction-threshold has been replaced by the flow-limit which is a
|
|
|
|
|
hard limit on the number of flows in the datapath. It defaults to 200,000
|
|
|
|
|
flows. OVS automatically adjusts this number depending on network
|
|
|
|
|
conditions.
|
2014-02-06 16:04:05 -08:00
|
|
|
- Added IPv6 support for active and passive socket communications.

|
|
|
* Experimental support for OpenFlow 1.1 (in addition to 1.2 and
|
|
|
|
|
1.3, which had experimental support in 1.10).
|
2013-09-01 18:30:17 -07:00
|
|
|
* Experimental protocol support for OpenFlow 1.1+ groups. This
|
|
|
|
|
does not yet include an implementation in the Open vSwitch
|
|

|
|
|
|
|
* Experimental protocol support for OpenFlow 1.2+ meters. This
|
|
|
|
|
does not yet include an implementation in the Open vSwitch

|
2013-05-09 15:24:16 +03:00
|
|
|
* New support for matching outer source and destination IP address
|
|
|
|
|
of tunneled packets, for tunnel ports configured with the newly

2013-07-23 15:03:52 -07:00
|
|
|
added "remote_ip=flow" and "local_ip=flow" options.
|
2013-08-06 12:57:16 -07:00
|
|
|
* Support for matching on metadata 'pkt_mark' for interacting with
|
|
|
|
|
other system components. On Linux this corresponds to the skb
|
|
|
|
|
mark.
|
2013-08-28 16:13:41 -07:00
|
|
|
* Support matching, rewriting SCTP ports

|
|
|
- The flow eviction threshold has been moved to the Open_vSwitch table.
|
2013-06-24 08:38:22 -07:00
|
|
|
- Database names are now mandatory when specifying ovsdb-server options
|
|
|
|
|

|
|
|

|
- Added ovs-dev.py, a utility script helpful for Open vSwitch developers.
|
2013-08-02 11:38:51 -07:00
|
|
|
- Support for Linux kernels up to 3.10
|
2013-08-06 09:45:07 -07:00
|
|
|
- ovs-ofctl:
|
|
|
|
|
* New "ofp-parse" for printing OpenFlow messages read from a file.
|
2013-09-01 18:30:17 -07:00
|
|
|
* New commands for OpenFlow 1.1+ groups.
|
2013-08-21 13:49:04 -07:00
|
|
|
- Added configurable flow caching support to IPFIX exporter.
|
2013-09-03 09:54:51 -07:00
|
|
|
- Dropped support for Linux pre-2.6.32.
|
2013-09-17 14:36:41 -07:00
|
|
|
- Log file timestamps and ovsdb commit timestamps are now reported
|
|
|
|
|
with millisecond resolution. (Previous versions only reported
|
|
|
|
|
whole seconds.)
|

|
v1.11.0 - 28 Aug 2013
|
2013-02-04 21:55:32 -08:00
|
|
|
---------------------
|
2013-05-20 17:48:49 -07:00
|
|
|
- Support for megaflows, which allows wildcarding in the kernel (and
|
|
|
|
|
any dpif implementation that supports wildcards). Depending on
|
|
|
|
|
the flow table and switch configuration, flow set up rates are
|
|
|
|
|
close to the Linux bridge.
|
2013-04-19 16:25:56 -07:00
|
|
|
- The "tutorial" directory contains a new tutorial for some advanced
|
|
|
|
|
Open vSwitch features.
|
2013-02-04 18:28:57 -08:00
|
|
|
- Stable bond mode has been removed.
|
2013-02-04 18:45:54 -08:00
|
|
|
- The autopath action has been removed.
|
2013-02-21 21:52:04 -08:00
|
|
|
- New support for the data encapsulation format of the LISP tunnel
|
|
|
|
|
protocol (RFC 6830). An external control plane or manual flow
|
|
|
|
|
setup is required for EID-to-RLOC mapping.
|
2013-03-06 16:08:23 +09:00
|
|
|
- OpenFlow:
|
2013-03-06 16:08:12 +09:00
|
|
|
* The "dec_mpls_ttl" and "set_mpls_ttl" actions from OpenFlow
|
|
|
|
|
1.1 and later are now implemented.
|
2013-03-05 16:27:55 -08:00
|
|
|
* New "stack" extension for use in actions, to push and pop from
|
|
|
|
|
NXM fields.
|
2013-05-08 11:03:06 -07:00
|
|
|
* The "load" and "set_field" actions can now modify the "in_port". (This
|
|
|
|
|
allows one to enable output to a flow's input port by setting the
|
|
|
|
|
in_port to some unused value, such as OFPP_NONE.)
|
2013-03-15 13:47:53 -07:00
|
|
|
- ovs-dpctl:
|
|
|
|
|
* New debugging commands "add-flow", "mod-flow", "del-flow".
|
2013-08-03 12:23:14 -07:00
|
|
|
* "dump-flows" now has a -m option to increase output verbosity.
|
2013-05-14 18:24:43 -07:00
|
|
|
- In dpif-based bridges, cache action translations, which can improve
|
|
|
|
|
flow set up performance by 80% with a complicated flow table.
|
2013-04-04 10:42:47 -07:00
|
|
|
- New syslog format, prefixed with "ovs|", to be easier to filter.
|
2013-04-12 12:58:27 -07:00
|
|
|
- RHEL: Removes the default firewall rule that allowed GRE traffic to
|
|
|
|
|
pass through. Any users that relied on this automatic firewall hole
|
|
|
|
|
will have to manually configure it. The ovs-ctl(8) manpage documents
|
|
|
|
|
the "enable-protocol" command that can be used as an alternative.
|
2013-05-15 14:31:06 -07:00
|
|
|
- New CFM demand mode which uses data traffic to indicate interface
|
|
|
|
|
liveness.
|
2013-02-04 21:55:32 -08:00
|
|
|
|
2013-05-01 14:30:38 -07:00
|
|
|
v1.10.0 - 01 May 2013
|
2013-02-04 15:56:36 -08:00
|
|
|
---------------------
|
2013-01-17 10:32:30 -08:00
|
|
|
- Bridge compatibility support has been removed. Any uses that
|
|
|
|
|
rely on ovs-brcompatd will have to stick with Open vSwitch 1.9.x
|
|
|
|
|
or adapt to native Open vSwitch support (e.g. use ovs-vsctl instead
|
|
|
|
|
of brctl).
|
2012-12-08 12:32:33 -08:00
|
|
|
- The maximum size of the MAC learning table is now configurable.
|
2013-01-04 18:34:26 -08:00
|
|
|
- With the Linux datapath, packets for new flows are now queued
|
|
|
|
|
separately on a per-port basis, so it should no longer be
|
|
|
|
|
possible for a large number of new flows arriving on one port to
|
|
|
|
|
prevent new flows from being processed on other ports.
|
2013-03-18 09:58:47 -07:00
|
|
|
- ovs-vsctl:
|
|
|
|
|
* Previously ovs-vsctl would retry connecting to the database forever,
|
|
|
|
|
causing it to hang if ovsdb-server was not running. Now, ovs-vsctl
|
|
|
|
|
only tries once by default (use --retry to try forever). This change
|
|
|
|
|
means that you may want to remove uses of --timeout to avoid hangs
|
|
|
|
|
in ovs-vsctl calls.
|
|
|
|
|
* Many "ovs-vsctl" database commands now accept an --if-exists option.
|
|
|
|
|
Please refer to the ovs-vsctl manpage for details.
|
2013-02-04 14:13:25 -08:00
|
|
|
- OpenFlow:
|
2013-02-04 14:28:05 -08:00
|
|
|
- Experimental support for newer versions of OpenFlow. See
|
|
|
|
|
the "What versions of OpenFlow does Open vSwitch support?"
|
|
|
|
|
question in the FAQ for more details.
|
2013-02-04 14:13:25 -08:00
|
|
|
- The OpenFlow "dp_desc" may now be configured by setting the
|
|
|
|
|
value of other-config:dp-desc in the Bridge table.
|
|
|
|
|
- It is possible to request the OpenFlow port number with the
|
|
|
|
|
"ofport_request" column in the Interface table.
|
2013-03-08 10:54:13 -08:00
|
|
|
- The NXM flow_removed message now reports the OpenFlow table ID
|
|
|
|
|
from which the flow was removed.
|
2013-02-04 21:45:29 -08:00
|
|
|
- Tunneling:
|
|
|
|
|
- New support for the VXLAN tunnel protocol (see the IETF draft here:
|
2013-02-24 18:58:03 -08:00
|
|
|
http://tools.ietf.org/html/draft-mahalingam-dutt-dcops-vxlan-03).
|
2013-02-04 21:45:29 -08:00
|
|
|
- Tunneling requires the version of the kernel module paired with
|
|
|
|
|
Open vSwitch 1.9.0 or later.
|
|
|
|
|
- Inheritance of the Don't Fragment bit in IP tunnels (df_inherit)
|
|
|
|
|
is no longer supported.
|
|
|
|
|
- Path MTU discovery is no longer supported.
|
2013-03-11 16:00:17 -07:00
|
|
|
- CAPWAP tunneling support removed.
|
|
|
|
|
- Tunnels with multicast destination ports are no longer supported.
|
2013-02-04 14:13:25 -08:00
|
|
|
- ovs-dpctl:
|
|
|
|
|
- The "dump-flows" and "del-flows" no longer require an argument
|
|
|
|
|
if only one datapath exists.
|
|
|
|
|
- ovs-appctl:
|
|
|
|
|
- New "vlog/disable-rate-limit" and "vlog/enable-rate-limit"
|
|
|
|
|
commands available allow control over logging rate limits.
|
|
|
|
|
- New "dpif/dump-dps", "dpif/show", and "dpif/dump-flows" command
|
|
|
|
|
that mimic the equivalent ovs-dpctl commands.
|
|
|
|
|
- The ofproto library is now responsible for assigning OpenFlow port
|
|
|
|
|
numbers. An ofproto implementation should assign them when
|
|
|
|
|
port_construct() is called.
|
|
|
|
|
- All dpif-based bridges of a particular type share a common
|
|
|
|
|
datapath called "ovs-<type>", e.g. "ovs-system". The ovs-dpctl
|
|
|
|
|
commands will now return information on that shared datapath. To
|
|
|
|
|
get the equivalent bridge-specific information, use the new
|
|
|
|
|
"ovs-appctl dpif/*" commands.
|
2013-01-08 15:29:44 -08:00
|
|
|
- Backward-incompatible changes:
|
|
|
|
|
- Earlier Open vSwitch versions treated ANY as a wildcard in flow
|
|
|
|
|
syntax. OpenFlow 1.1 adds a port named ANY, which introduces a
|
|
|
|
|
conflict. ANY was rarely used in flow syntax, so we chose to
|
|
|
|
|
retire that meaning of ANY in favor of the OpenFlow 1.1 meaning.
|
2013-02-04 21:45:29 -08:00
|
|
|
- Patch ports no longer require kernel support, so they now work
|
|
|
|
|
with FreeBSD and the kernel module built into Linux 3.3 and later.
|
2013-04-22 10:01:14 -07:00
|
|
|
- New "sample" action.
|
2012-11-05 11:05:18 -08:00
|
|
|
|
2012-10-24 16:13:31 -07:00

|
|
v1.9.0 - 26 Feb 2013
|
|
|
|
|
------------------------
|
2012-11-13 19:19:36 +02:00
|
|
|
- Datapath:
|
|
|
|
|
- Support for ipv6 set action.
|
|
|
|
|
- SKB mark matching and setting.
|
2013-01-16 11:19:21 +00:00
|
|
|
- support for Linux kernels up to 3.8
|
2012-07-25 22:51:05 +02:00
|
|
|
- FreeBSD is now a supported platform, thanks to code contributions from
|
|
|
|
|
Gaetano Catalli, Ed Maste, and Giuseppe Lettieri.
|
2012-07-18 23:50:03 -07:00
|
|
|
- ovs-bugtool: New --ovs option to report only OVS related information.
|
2012-07-18 10:30:47 -07:00
|
|
|
- New %t and %T log escapes to identify the subprogram within a
|
|
|
|
|
cooperating group of processes or threads that emitted a log message.
|
|
|
|
|
The default log patterns now include this information.
|
2012-07-18 12:02:19 +09:00
|
|
|
- OpenFlow:
|
2012-07-19 09:21:49 -07:00
|
|
|
- Allow bitwise masking for SHA and THA fields in ARP, SLL and TLL
|
|
|
|
|
fields in IPv6 neighbor discovery messages, and IPv6 flow label.
|
2012-10-19 02:37:37 +09:00
|
|
|
- Adds support for writing to the metadata field for a flow.
|
2013-02-04 21:45:29 -08:00
|
|
|
- Tunneling:
|
|
|
|
|
- The tunneling code no longer assumes input and output keys are
|
|
|
|
|
symmetric. If they are not, PMTUD needs to be disabled for
|
|
|
|
|
tunneling to work. Note this only applies to flow-based keys.
|
|
|
|
|
- New support for a nonstandard form of GRE that supports a 64-bit key.
|
|
|
|
|
- Tunnel Path MTU Discovery default value was set to 'disabled'.
|
|
|
|
|
This feature is deprecated and will be removed soon.
|
|
|
|
|
- Tunnel header caching removed.
|
2012-09-20 08:40:29 -07:00
|
|
|
- ovs-ofctl:
|
|
|
|
|
- Commands and actions that accept port numbers now also accept keywords
|
|
|
|
|
that represent those ports (such as LOCAL, NONE, and ALL). This is
|
|
|
|
|
also the recommended way to specify these ports, for compatibility
|
|
|
|
|
with OpenFlow 1.1 and later (which use the OpenFlow 1.0 numbers
|
|
|
|
|
for these ports for different purposes).
|
2012-08-03 11:56:33 -07:00
|
|
|
- ovs-dpctl:
|
2012-07-27 23:59:23 -07:00
|
|
|
- Support requesting the port number with the "port_no" option in
|
|
|
|
|
the "add-if" command.
|
2012-08-03 11:56:33 -07:00
|
|
|
- ovs-pki: The "online PKI" features have been removed, along with
|
|
|
|
|
the ovs-pki-cgi program that facilitated it, because of some
|
|
|
|
|
alarmist insecurity claims. We do not believe that these claims
|
|
|
|
|
are true, but because we do not know of any users for this
|
|
|
|
|
feature it seems better on balance to remove it. (The ovs-pki-cgi
|
|
|
|
|
program was not included in distribution packaging.)
|
2012-09-05 10:35:20 -07:00
|
|
|
- ovsdb-server now enforces the immutability of immutable columns. This
|
|
|
|
|
was not enforced in earlier versions due to an oversight.
|
2012-09-26 09:57:28 -07:00
|
|
|
- The following features are now deprecated. They will be removed no
|
|
|
|
|
earlier than February 2013. Please email dev@openvswitch.org with
|
|
|
|
|
concerns.
|
2012-12-27 13:30:59 -08:00
|
|
|
- Bridge compatibility.
|
2012-09-26 09:57:28 -07:00
|
|
|
- Stable bond mode.
|
|
|
|
|
- The autopath action.
|
|
|
|
|
- Interface type "null".
|
|
|
|
|
- Numeric values for reserved ports (see "ovs-ofctl" note above).
|
2012-10-29 18:12:03 +02:00
|
|
|
- Tunnel Path MTU Discovery.
|
2012-11-05 13:40:17 -08:00
|
|
|
- CAPWAP tunnel support.
|
2012-11-05 11:05:18 -08:00
|
|
|
- The data in the RARP packets can now be matched in the same way as the
|
|
|
|
|
data in ARP packets.
|

*** Internal only release ***
|
2012-06-12 09:40:11 -07:00
|
|
|
- New FAQ. Please send updates and additions!
|
2012-07-03 22:17:14 -07:00
|
|
|
- Authors of controllers, please read the new section titled "Action
|
|
|
|
|
Reproduction" in DESIGN, which describes an Open vSwitch change in
|
|
|
|
|
behavior in corner cases that may affect some controllers.
|
2012-06-28 15:52:40 -07:00
|
|
|
- ovs-l3ping:
|
|
|
|
|
- A new test utility that can create L3 tunnel between two Open
|
|
|
|
|
vSwitches and detect connectivity issues.
|
2012-05-24 14:17:55 -07:00
|
|
|
- ovs-ofctl:
|
2012-07-12 13:32:47 -07:00
|
|
|
- New --sort and --rsort options for "dump-flows" command.
|
2012-05-24 14:17:55 -07:00
|
|
|
- "mod-port" command can now control all OpenFlow config flags.
|
2012-05-22 22:06:03 -07:00
|
|
|
- OpenFlow:
|
2012-05-22 22:49:31 -07:00
|
|
|
- Allow general bitwise masking for IPv4 and IPv6 addresses in
|
|
|
|
|
IPv4, IPv6, and ARP packets. (Previously, only CIDR masks
|
2012-05-22 22:06:03 -07:00
|
|
|
were allowed.)
|
|
|
|
|
- Allow support for arbitrary Ethernet masks. (Previously, only
|
|
|
|
|
the multicast bit in the destination address could be individually
|
2018-05-25 17:11:07 -07:00
|
|
|
masked.)
|
2012-06-27 01:09:44 +12:00
|
|
|
- New field OXM_OF_METADATA, to align with OpenFlow 1.1.
|
2012-06-11 11:23:06 -07:00
|
|
|
- The OFPST_QUEUE request now reports an error if a specified port or
|
|
|
|
|
queue does not exist, or for requests for a specific queue on all
|
|
|
|
|
ports, if the specified queue does not exist on any port. (Previous
|
|
|
|
|
versions generally reported an empty set of results.)
|
2012-07-12 14:18:05 -07:00
|
|
|
- New "flow monitor" feature to allow controllers to be notified of
|
|
|
|
|
flow table changes as they happen.
|
2012-06-06 15:22:52 -07:00
|
|
|
- Additional protocols are not mirrored and dropped when forward-bpdu is
|
|
|
|
|
false. For a full list, see the ovs-vswitchd.conf.db man page.
|
2012-06-07 15:27:22 -07:00
|
|
|
- Open vSwitch now sends RARP packets in situations where it previously
|
|
|
|
|
sent a custom protocol, making it consistent with behavior of QEMU and
|
|
|
|
|
VMware.
|
2012-07-02 04:32:44 -07:00
|
|
|
- All Open vSwitch programs and log files now show timestamps in UTC,
|
|
|
|
|
instead the local timezone, by default.
|
2012-05-08 11:11:33 -07:00

|
v1.7.0 - 30 Jul 2012
|
2012-02-24 10:32:36 -08:00
|
|
|
------------------------
|
2012-03-09 09:55:45 -08:00
|
|
|
- kernel modules are renamed. openvswitch_mod.ko is now
|
|
|
|
|
openvswitch.ko and brcompat_mod.ko is now brcompat.ko.
|
2012-03-08 14:44:54 -08:00
|

|
|
|
|
Internetwork Control (0xc0).
|
2012-04-05 14:30:23 -07:00
|

|
|
|
|
|
multipart messages.
|
|
|
|
|
- ovs-ofctl:
|
|
|

|
|
|
- LACP bonds no longer fall back to balance-slb when negotiations fail.
|
|
|
|
|
Instead they drop traffic.
|
2012-01-11 17:23:38 -08:00
|
|
|
- The default bond_mode changed from SLB to active-backup, to protect
|
|
|
|
|
unsuspecting users from the significant risks of SLB bonds (which are
|
|
|
|
|
documented in vswitchd/INTERNALS).
|
2012-01-25 17:41:44 -08:00
|
|
|
- Load balancing can be disabled by setting the bond-rebalance-interval
|

- NXM flow dumps now include times elapsed toward idle and hard
|
|
|
|
|
timeouts.
|
|
|
|
|
- Added an OpenFlow extension NXT_SET_ASYNC_CONFIG that allows
|
|
|
|
|
controllers more precise control over which OpenFlow messages they
|
|
|
|
|
receive asynchronously.
|
2012-02-15 10:37:03 -08:00
|
|

|
|
|
|
over output to OFPP_CONTROLLER.
|
2012-02-16 16:33:14 -08:00
|
|
|
- When QoS settings for an interface do not configure a default queue
|
|
|
|
|
(queue 0), Open vSwitch now uses a default configuration for that
|
|
|
|
|
queue, instead of dropping all packets as in previous versions.
|
2012-02-08 15:29:15 -08:00
|
|
|
- Logging:
|
|
|
|

|
|
|
|
all the daemons. An example of the default format is
|
|
|
|
|
2012-01-27T16:35:17Z. ovs-appctl can be used to change the default
|
|
|
|
|
format as before.
|
|
|
|
|
- The syntax of commands and options to set log levels was simplified,
|
|
|
|
|
to make it easier to remember.
|
2012-02-01 10:27:30 -08:00
|
|
|
- New support for limiting the number of flows in an OpenFlow flow
|
|
|
|
|
table, with configurable policy for evicting flows upon
|
|
|
|
|
overflow. See the Flow_Table table in ovs-vswitch.conf.db(5)

|
|
|
for more information.
|

- ofproto-provider interface:
|
|
|
|
|
- "struct rule" has a new member "used" that ofproto implementations
|
|
|
|

|
|
- ovsdb-client:
|
|
|
|
|

|
|
|
|
|
a timestamp with every update.
|
2012-02-02 15:48:13 -08:00
|

|
|
|
|
|
in old Linux versions. (This feature is deprecated. When
|
|
|
|
|
broken device drivers are no longer in widespread use, we will
|
|
|
|
|
delete this feature.) See ovs-vswitchd.conf.db(5) for more
|
|
|
|
|
information.
|

- ovs-vswitchd:
|
2011-11-23 00:04:58 -08:00
|
|
|
- Don't require the "normal" action to use mirrors. Traffic will
|
|
|
|
|
now be properly mirrored for any flows, regardless of their
|
|
|
|
|
actions.
|
2011-11-20 15:12:36 -08:00
|
|

|
|
|
|
|
device instead of having to be told explicitly.
|

|
Xen packages.
|
2011-11-03 10:30:04 -07:00
|
|
|
- RHEL packaging now supports integration with Red Hat network scripts.
|
2011-12-15 13:39:38 -08:00
|
|

- bonding:
|
|
|
|
|
- Post 1.4.*, OVS will be changing the default bond mode from balance-slb
|
|
|
|
|
to active-backup. SLB bonds carry significant risks with them
|
|
|
|
|
(documented vswitchd/INTERNALS) which we want to prevent unsuspecting
|
|
|
|
|
users from running into. Users are advised to update any scripts or
|
|
|
|
|
configuration which may be negatively impacted by explicitly setting
|
|
|
|
|
the bond mode which they want to use.

|
- OpenFlow:
|
|
|
|
|
- Added an OpenFlow extension which allows the "output" action to accept
|
|
|
|
|
NXM fields.
|
2011-09-12 16:19:57 -07:00
|
|

|
|
|
- ovs-appctl:
|
2011-09-26 15:40:53 -07:00
|
|
|
- New "version" command to determine version of running daemon.
|
|
|
|
|
- If no argument is provided for "cfm/show", displays detailed
|
|
|
|
|
information about all interfaces with CFM enabled.
|
2011-09-26 15:44:46 -07:00
|
|

- New "set-if" command to modify a datapath port's configuration.
|
2011-08-09 09:24:18 -07:00
|
|
|
- ovs-vswitchd:
|
|
|
|
|
- The software switch now supports 255 OpenFlow tables, instead
|
|
|
|
|
of just one. By default, only table 0 is consulted, but the
|
|
|
|
|
new NXAST_RESUBMIT_TABLE action can look up in additional
|
|
|
|
|
tables. Tables 128 and above are reserved for use by the
|
|
|
|
|
switch itself; please use only tables 0 through 127.
|
2011-10-14 09:48:17 -07:00
|
|
|
- Add support for 802.1D spanning tree (STP).
|
Implement new fragment handling policy.
Until now, OVS has handled IP fragments more awkwardly than necessary. It
has not been possible to match on L4 headers, even in fragments with offset
0 where they are actually present. This means that there was no way to
implement ACLs that treat, say, different TCP ports differently, on
fragmented traffic; instead, all decisions for fragment forwarding had to
be made on the basis of L2 and L3 headers alone.
This commit improves the situation significantly. It is still not possible
to match on L4 headers in fragments with nonzero offset, because that
information is simply not present in such fragments, but this commit adds
the ability to match on L4 headers for fragments with zero offset. This
means that it becomes possible to implement ACLs that drop such "first
fragments" on the basis of L4 headers. In practice, that effectively
blocks even fragmented traffic on an L4 basis, because the receiving IP
stack cannot reassemble a full packet when the first fragment is missing.
This commit works by adding a new "fragment type" to the kernel flow match
and making it available through OpenFlow as a new NXM field named
NXM_NX_IP_FRAG. Because OpenFlow 1.0 explicitly says that the L4 fields
are always 0 for IP fragments, it adds a new OpenFlow fragment handling
mode that fills in the L4 fields for "first fragments". It also enhances
ovs-ofctl to allow users to configure this new fragment handling mode and
to parse the new field.

Bug #7557.
2011-10-19 21:33:44 -07:00
|
|
|
- Fragment handling extensions:
|
|
|
|
|
- New OFPC_FRAG_NX_MATCH fragment handling mode, in which L4
|
|
|
|
|
fields are made available for matching in fragments with
|
|
|
|
|
offset 0.
|
|
|
|
|
- New NXM_NX_IP_FRAG match field for matching IP fragments (usable
|
|
|
|
|
via "ip_frag" in ovs-ofctl).
|
|
|
|
|
- New ovs-ofctl "get-frags" and "set-frags" commands to get and set
|
|
|
|
|
fragment handling policy.
|
2011-12-21 11:01:45 -08:00
|
|
|
- CAPWAP tunneling now supports an extension to transport a 64-bit key.
|
|
|
|
|
By default it remains compatible with the old version and other
|
2011-09-12 10:43:46 -07:00
|
|
|
standards-based implementations.
|
2011-09-16 15:23:37 -07:00
|
|
|
- Flow setups are now processed in a round-robin manner across ports
|
|
|
|
|
to prevent any single client from monopolizing the CPU and conducting
|
|
|
|
|
a denial of service attack.
|
2011-09-23 17:03:03 -07:00
|
|
|
- Added support for native VLAN tagging. A new "vlan_mode"
|
|
|
|
|
parameter can be set for "port". Possible values: "access",
|
|
|
|
|
"trunk", "native-tagged" and "native-untagged".
|
2011-10-24 10:36:01 -07:00
|
|
|
- test-openflowd has been removed. Please use ovs-vswitchd instead.

2011-04-26 09:42:18 -07:00
|
|
|
------------------------
|
2011-08-02 23:15:30 -07:00
|
|
|
- New "ofproto" abstraction layer to ease porting to hardware
|
|
|
|
|
switching ASICs.
|
|
|
|
|
- Packaging for Red Hat Enterprise Linux 5.6 and 6.0.
|
|
|
|
|
- Datapath support for Linux kernels up to 3.0.
|
|
|
|
|
- OpenFlow:
|
|
|
|
|
- New "bundle" and "bundle_load" action extensions.
|
|
|
|
|
- Database:
|
|
|
|
|
- Implement table unique constraints.
|
|
|
|
|
- Support cooperative locking between callers.
|
|
|
|
|
- ovs-dpctl:
|
|
|
|
|
- New "-s" option for "show" command prints packet and byte
|
|
|
|
|
counters for each port.
|
2011-07-27 14:58:10 -07:00
|
|
|
- ovs-ofctl:
|
|
|
|
|
- New "--readd" option for "replace-flows".
|
2011-05-24 13:03:58 -07:00
|
|
|
- ovs-vsctl:
|
|
|
|
|
- New "show" command to print an overview of configuration.
|
2011-08-02 23:15:30 -07:00
|
|
|
- New "comment" command to add remark that explains intentions.
|
2011-06-08 09:15:38 -07:00
|
|
|
- ovs-brcompatd has been rewritten to fix long-standing bugs.
|
2011-06-07 09:40:53 -07:00
|
|
|
- ovs-openflowd has been renamed test-openflowd and moved into the
|
|
|
|
|
tests directory. Its presence confused too many users. Please
|
|
|
|
|
use ovs-vswitchd instead.
|
2011-08-02 23:15:30 -07:00
|
|
|
- New ovs-benchmark utility to test flow setup performance.
|
|
|
|
|
- A new log level "off" has been added. Configuring a log facility
|
|
|
|
|
"off" prevents any messages from being logged to it. Previously,
|
|
|
|
|
"emer" was effectively "off" because no messages were ever logged at
|
|
|
|
|
level "emer". Now, errors that cause a process to exit are logged
|
|
|
|
|
at "emer" level.
|
2011-06-22 11:07:33 -07:00
|
|
|

|
|
|
|
|
--with-l26-source has been renamed --with-linux-source. The old
|
|
