- OVSDB:
* Changed format in which ovsdb transactions are stored in database files.
Now each transaction contains diff of data instead of the whole new
value of a column.
New ovsdb-server process will be able to read old database format, but
old processes will *fail* to read database created by the new one.
For cluster and active-backup service models follow upgrade instructions
in 'Upgrading from version 2.14 and earlier to 2.15 and later' section
of ovsdb(7).
* New unixctl command 'ovsdb-server/get-db-storage-status' to show the
status of the storage that's backing a database.
* New unixctl command 'ovsdb-server/memory-trim-on-compaction on|off'.
If turned on, ovsdb-server will try to reclaim all the unused memory
after every DB compaction back to OS. Disabled by default.
* Maximum backlog on RAFT connections limited to 500 messages or 4GB.
Once threshold reached, connection is dropped (and re-established).
Use the 'cluster/set-backlog-threshold' command to change limits.
- DPDK:
* Removed support for vhost-user dequeue zero-copy.
* Add support for DPDK 20.11.
- Userspace datapath:
* Add the 'pmd' option to "ovs-appctl dpctl/dump-flows", which
restricts a flow dump to a single PMD thread if set.
* New 'options:dpdk-vf-mac' field for DPDK interface of VF ports,
that allows configuring the MAC address of a VF representor.
* Add generic IP protocol support to conntrack. With this change, all
none UDP, TCP, and ICMP traffic will be treated as general L3
traffic, i.e. using 3 tupples.
* Add parameters 'pmd-auto-lb-load-threshold' and
'pmd-auto-lb-improvement-threshold' to configure PMD auto load balance
behaviour.
- The environment variable OVS_UNBOUND_CONF, if set, is now used
as the DNS resolver's (unbound) configuration file.
- Linux datapath:
* Support for kernel versions up to 5.8.x.
- Terminology:
* The terms "master" and "slave" have been replaced by "primary" and
"secondary", respectively, for OpenFlow connection roles.
* The term "slave" has been replaced by "member", for bonds, LACP, and
OpenFlow bundle actions.
- Support for GitHub Actions based continuous integration builds has been
added.
- Bareudp Tunnel
* Bareudp device support is present in linux kernel from version 5.7
* Kernel bareudp device is not backported to ovs tree.
* Userspace datapath support is not added
- ovs-dpctl and 'ovs-appctl dpctl/':
* New commands '{add,mod,del}-flows' where added, which allow adding,
deleting, or modifying flows based on information read from a file.
- IPsec:
* Add option '--no-cleanup' to allow ovs-monitor-ipsec to stop without
tearing down IPsec tunnels.
* Add option '--no-restart-ike-daemon' to allow ovs-monitor-ipsec to start
without restarting ipsec daemon.
- Building the Linux kernel module from the OVS source tree is deprecated
* Support for the Linux kernel is capped at version 5.8
* Only bug fixes for the Linux OOT kernel module will be accepted.
* The Linux kernel module will be fully removed from the OVS source tree
in OVS branch 2.18
fix some do_patch error about local patch.

Subject: [PATCH] systemd: create runtime dirs
|
|
|
|
The recommendation would be to make use of "RuntimeDirectory=" and
|
|
"RuntimeDirectoryMode=" instead of 'mkdir' and 'chown' but since the
|
|
upstream service file uses 'chown' we will match this by using
|
|
'mkdir'. Without this the service will fail to start since these
|
|
directories won't exist.
