* github: Add GitHub Actions workflow.Ilya Maximets2020-11-261-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | This is an initial version of GitHub Actions support. It mostly mimics our current Travis CI build matrix with slight differences. The main issue is that we don't have ARM support here. Minor difference that we can not install 32-bit versions of libunwind and libunbound since those are not avaialble in repository. Higher concurrency level allows to finish all tests less than in 20 minutes. Which is 3 times faster than in Travis. .travis folder renamed to .ci to highlight that it used not only for Travis CI. Travis CI support will be reduced to only test ARM builds soon and will be completely removed when travis-ci.org will be turned into read-only mode.

* netdev-dpdk: Add option to configure VF MAC address.Gaetan Rivet2020-11-161-0/+51
| | | | | | | | | | | | | | | | | | | | In some cloud topologies, using DPDK VF representors in guest requires configuring a VF before it is assigned to the guest. A first basic option for such configuration is setting the VF MAC address. Add a key 'dpdk-vf-mac' to the 'options' column of the Interface table. This option can be used as such: $ ovs-vsctl add-port br0 dpdk-rep0 -- set Interface dpdk-rep0 type=dpdk \ options:dpdk-vf-mac=00:11:22:33:44:55 Suggested-by: Ilya Maximets <i.maximets@ovn.org> Acked-by: Eli Britstein <elibr@nvidia.com> Acked-by: Kevin Traynor <ktraynor@redhat.com> Signed-off-by: Gaetan Rivet <grive@u256.net> Signed-off-by: Ilya Maximets <i.maximets@ovn.org>

* release-process: Policy for unmaintained branches.Ilya Maximets2020-11-102-1/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While only 2 branches are formally maintained (LTS and latest release), OVS team usually provides stable releases for other branches too, at least for branches between LTS and latest. When transition period ends for an old LTS, we, according to backporting-patches.rst, could stop backporting bug fixes to branches older than new LTS. While this might be OK for an upstream project it doesn't sound like a user-friendly policy just because it means that we're dropping support for branches released less than a year ago. Below addition to the release process might make the process a bit smoother in terms that we will not drop support for not so old branches even after the transition period, if committers will follow the "as far as it goes" backporting policy. And we will provide stable releases for these branches for at least 2 years (these releases could be less frequent than releases on LTS branches). After 2 year period (4 releases) committers are still free to backport fixes they think are needed on older branches, however we will likely not provide actual releases on these branches, unless it's specially requested and discussed. Additionally, "4 releases" policy aligns with the DPDK LTS support policy, i.e. we will be able to validate and release last OVS releases with the last available DPDK LTS, e.g. OVS 2.11 last stable release will likely be released with the 18.11 EOL release validated.

* release-process: Standardize designation of new LTS releases.Ilya Maximets2020-11-101-6/+26
| | | | | | | | | | | | | | | | | | | Standardize that we will mark a new release as LTS every two years to avoid situation where we have a really old LTS branch that no-one actually uses, but we have to support and provide releases for it. This will also make release process more predictable, so users will be able to rely on it and plan their upgrades accordingly. As a bonus, 2 years support cycle kind of aligns with 2 years support cycle of DPDK LTS releases. Still keeping a window for us to discuss and avoid marking some particular release as LTS in case of significant issues with it.

* release-process: Add transition period for LTS releases.Ilya Maximets2020-11-101-4/+7
| | | | | | | | | | | | | | | | | | | | | | | While LTS change happens, according to release-process.rst, we're immediately dropping support for the old LTS and, according to backporting-patches.rst could stop backporting bug fixes to branches older than new LTS. While this might be OK for an upstream project (some upstream projects like QEMU doesn't support anything at all except the last release) it doesn't sound like a user-friendly policy. Below addition to the release process might make the process a bit smoother in terms that we will continue support of branches a little bit longer even after changing current LTS, i.e. providing at least a minimal transition period (1 release frame) for users of old LTS. Effectively, this change means that we will support branch-2.5 until 2.15 release, i.e. we will provide the last release, if any, on branch-2.5 somewhere around Feb 2021. (I don't actually expect many fixes there) Signed-off-by: Ilya Maximets <i.maximets@ovn.org> Acked-by: Flavio Leitner <fbl@sysclose.org> Acked-by: Kevin Traynor <ktraynor@redhat.com>
* releases: Mark 2.13 as a new LTS release.Ilya Maximets2020-11-101-1/+1
| | | | | | | | | | | | | | | | | 2.5 release is 4.5 years old and I'm not aware of anyone who actually uses it today. Release process documentation says that there is no strict time period for nominating a new LTS release and that usually it happens once in a two years. So, proposing to nominate 2.13 as our new LTS release since it's a first release that doesn't include OVN inside, so we will formally not have to support it in this repository in case there are major issues that might be hard to fix.

| | | | | | | | | | | | | | | | | | | | | | | GTP, GPRS Tunneling Protocol, is a group of IP-based communications protocols used to carry general packet radio service (GPRS) within GSM, UMTS and LTE networks. GTP protocol has two parts: Signalling (GTP-Control, GTP-C) and User data (GTP-User, GTP-U). GTP-C is used for setting up GTP-U protocol, which is an IP-in-UDP tunneling protocol. Usually GTP is used in connecting between base station for radio, Serving Gateway (S-GW), and PDN Gateway (P-GW). This patch implements GTP-U protocol for userspace datapath, supporting only required header fields and G-PDU message type.

* lib/stream-windows.c: Grant Access Privilege of Named Pipe to CreatorNing Wu2020-01-241-1/+2
| | | | | | | | | | | | | | Current implementation of ovs on windows only allows LocalSystem and Administrators to access the named pipe created with API of ovs. Thus any service that needs to invoke the API to create named pipe has to run as System account to interactive with ovs. It causes the system more vulnerable if one of those services was break into. The patch adds the creator owner account to allowed ACLs.
