* util: Fix abs_file_name() bugs on Windows.Ben Pfaff2018-08-031-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | abs_file_name() believed that a file name that begins with / or contains : is absolute and that any other file name is relative. On Windows, this is wrong in at least the following ways: * / and \ are interchangeable on Windows. * A name that begins with \\ or // is also absolute. * A name that begins with X: but not X:\ is not absolute. * A name with : in some position other than the second position is not absolute (although it might not be valid either?). Furthermore, Windows has more than one current working directory (one per volume letter), so trying to make a file name absolute by just prefixing the current working directory for the current volume results in silliness. This patch attempts to fix the problem. This makes OVS link against shlwapi, which is needed to use PathIsRelative(). Found by inspection.

* Docs: Improve OVS DPDK version mapping notice.Ian Stokes2018-07-242-4/+8
| | | | | | | | | | | | | A common issue is users pairing the incorrect version of OVS to DPDK when working outside of the build tree. To avoid this, this commit updates the OVS DPDK documentation to explicitly flag that users should consult the OVS to DPDK release mapping in FAQ if working outside of the OVS build tree.

* dpif-netdev: Add SMC cache after EMC cacheYipeng Wang2018-07-241-0/+15
| | | | | | | | | | | | | | | | | | | | | | This patch adds a signature match cache (SMC) after exact match cache (EMC). The difference between SMC and EMC is SMC only stores a signature of a flow thus it is much more memory efficient. With same memory space, EMC can store 8k flows while SMC can store 1M flows. It is generally beneficial to turn on SMC but turn off EMC when traffic flow count is much larger than EMC size. SMC cache will map a signature to an dp_netdev_flow index in flow_table. Thus, we add two new APIs in cmap for lookup key by index and lookup index by key. For now, SMC is an experimental feature that it is turned off by default. One can turn it on using ovsdb options.

* rhel: rename openvswitch kmod rhel6 spec fileMartin Xu2018-07-121-4/+3
| | | | | | | | | | | | | | | | | | This patch only affects rhel6 spec file. The rhel6 kmod spec file is renamed from openvswitch-kmod-rhel6.spec to kmod-openvswitch-rhel6.spec . This is to prepare for the next patches to support building multiple kernel versions in the main package. The rename makes the spec file consistent with the resulted kmod-openvswitch-<version>.rpm, which is the real package with kernel module files.

| * dpdk: Support both shared and per port mempools.Ian Stokes2018-07-064-0/+224
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit re-introduces the concept of shared mempools as the default memory model for DPDK devices. Per port mempools are still available but must be enabled explicitly by a user. OVS previously used a shared mempool model for ports with the same MTU and socket configuration. This was replaced by a per port mempool model to address issues flagged by users such as: https://mail.openvswitch.org/pipermail/ovs-discuss/2016-September/042560.html However the per port model potentially requires an increase in memory resource requirements to support the same number of ports and configuration as the shared port model. This is considered a blocking factor for current deployments of OVS when upgrading to future OVS releases as a user may have to redimension memory for the same deployment configuration. This may not be possible for users. This commit resolves the issue by re-introducing shared mempools as the default memory behaviour in OVS DPDK but also refactors the memory configuration code to allow for per port mempools. This patch adds a new global config option, per-port-memory, that controls the enablement of per port mempools for DPDK devices. ovs-vsctl set Open_vSwitch . other_config:per-port-memory=true This value defaults to false; to enable per port memory 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. The mempool sweep functionality is also replaced with the sweep functionality from OVS 2.9 found in commits c77f692 (netdev-dpdk: Free mempool only when no in-use mbufs.) a7fb0a4 (netdev-dpdk: Add mempool reuse/free debug.) A new document to discuss the specifics of the memory models and example memory requirement calculations is also added.

* | DNS: Add basic support for asynchronous DNS resolvingYifeng Sun2018-07-062-7/+11
|/ | | | | | | | | | | | | | | | | | | | | | This patch is a simple implementation for the proposal discussed in https://mail.openvswitch.org/pipermail/ovs-dev/2017-August/337038.html and https://mail.openvswitch.org/pipermail/ovs-dev/2017-October/340013.html. It enables ovs-vswitchd and other utilities to use DNS names when specifying OpenFlow and OVSDB remotes. Below are some of the features and limitations of this patch: - Resolving is asynchornous in daemon context, avoiding blocking main loop; - Resolving is synchronous in general utility context; - Both IPv4 and IPv6 are supported; - The resolving API is thread-safe; - Depends on the unbound library; - When multiple ip addresses are returned, only the first one is used; - /etc/nsswitch.conf isn't respected as unbound library doesn't look at it; - For async-resolving, caller need to retry later; there is no callback.

* | ovsdb-idl: Redesign use of indexes.Ben Pfaff2018-06-121-71/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The design of the compound index feature in the C OVSDB IDL was unusual. Indexes were generally referenced only by name rather than by pointer, and could be obtained only from the top-level ovsdb_idl object. To iterate or otherwise search an index required explicitly creating a special ovsdb_idl_cursor object, which at least seemed somewhat heavy-weight given that it required a string lookup in a table of indexes. This commit redesigns the compound index interface. It discards the use of names for indexes, instead having clients pass in a pointer to the index object itself. It simplifies how indexes are created, gets rid of the need for explicit cursor objects, and updates all of the users to the new interface. The underlying reason for this commit is to make it easier in ovn-controller to keep track of the dependencies for a given function, by making the indexes explicit arguments to any function that needs to use them.

| * docs: Fix sflow documentation url and markup.Ian Stokes2018-04-211-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | The link url link for the blog in sflow documentation causes make check-docs to fail with a broken link warning. Fix this by correcting the url address. Also use correct markup for note regarding the configuration of sflow.

| * dpdk docs: Drop file share in libvirt config.Tiago Lam2018-04-211-15/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When explaining on how to add vhost-user ports to a guest, using libvirt, the following piece of configuration is used: <disk type='dir' device='disk'> <driver name='qemu' type='fat'/> <source dir='/usr/src/dpdk-stable-17.11.1'/> <target dev='vdb' bus='virtio'/> <readonly/> </disk> This is used to facilitate sharing of a DPDK directory between the host and the guest. However, for this to work selinux also needs to be configured (or disabled). Furthermore, if one is using Ubuntu, libvirtd would need to be added to complain only in AppArmor. Instead, in [1] it is advised to use wget to get the DPDK sources over the internet, which avoids this differentiation. Thus, we drop this piece of configuration here as well and keep the example configuration as simple as possible. This has been verified on both a Fedora 27 image and a Ubuntu 16.04 LTS image.

| * dpdk docs: Drop qemu-kvm for qemu-system-x86_64.Tiago Lam2018-04-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When explaining on how to add vhost-user ports to a guest, using libvirt, point to the qemu-system-x86_64 binary by default, instead of using qemu-kvm. The latter has been made obsolete and dropped from a number of distributions (although it is still available on Fedora). This has been verified on both a Fedora 27 image and a Ubuntu 16.04 LTS image.

| * netdev-dpdk: fix MAC address in port addr exampleMarcelo Ricardo Leitner2018-04-211-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The MAC address is always 6-bytes long, never 7. The extra :01 and :02 doesn't belong in there as it doesn't mean selecting one port or another. Instead, use an incrementing MAC address, which is what usually happens on such cards.
