* vlog: Ability to override the default log facility.Gurucharan Shetty2015-01-281-0/+13
| | | | | | | | | | | | | | | When Open vSwitch is run in hundreds of hypervisors, it is useful to collect log messages through log collectors. To collect log messages like this, it is useful to log them in a particular RFC5424 facility in the local system. The log collectors can then be used to collect logs anytime desired. This commit provides a sysadmin the ability to specify the facility through which the log messages are logged.

| | | | | | | | | | Commit 4a1f523f2d760 (lib: Move vconn.h to <openvswitch/vconn.h>) moved the definitions of struct vconn and struct pvconn into the public vconn.h header. This is unnecessary because the size and content of these structs is not part of the ABI. This commit moves them back.

* vlog: Rename the currently used term 'facility' as 'destination'.Gurucharan Shetty2015-01-081-19/+21
| | | | | | | | | | | | In OVS, we currently use the term 'facility' to mean the place where we log (syslog, console or file). In Linux's syslog() and rfc5424, the term 'facility' is used to specify what type of program is logging the message (e.g: LOG_DAEMON). This causes confusion while reading vlog's code. This commit changes the term 'facility' to 'destination'. Signed-off-by: Gurucharan Shetty <gshetty@nicira.com> Acked-by: Ben Pfaff <blp@nicira.com>

| | | | | | | | | | | | | This improves the general abstraction of OXM/NXM by eliminating direct knowledge of it from the meta-flow code and other places. Some function renaming might be called for; for example, mf_oxm_header() may not be the best name now that the function is implemented within nx-match.

Insert sampling action before output action and the output tunnel port is sent to datapath in the sampling action. Make datapath collect output tunnel info and send it back to userpace in upcall message with a new additional optional attribute. Add a tunnel ports map to make the tunnel port lookup faster in sampling upcalls in IPFIX exporter.

* ofp-actions: Centralize all OpenFlow action code for maintainability.Ben Pfaff2014-08-116-1299/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Until now, knowledge about OpenFlow has been somewhat scattered around the tree. Some of it is in ofp-actions, some of it is in ofp-util, some in separate files for individual actions, and most of the wire format declarations are in include/openflow. This commit centralizes all of that in ofp-actions. Encoding and decoding OpenFlow actions was previously broken up by OpenFlow version. This was OK with only OpenFlow 1.0 and 1.1, but each additional version added a new wrapper around the existing ones, which started to become hard to understand. This commit merges all of the processing for the different versions, to the extent that they are similar, making the version differences clearer. Previously, ofp-actions contained OpenFlow encoding and decoding, plus ofpact formatting, but OpenFlow parsing was separated into ofp-parse, which seems an odd division. This commit moves the parsing code into ofp-actions with the rest of the code. Before this commit, the four main bits of code associated with a particular ofpact--OpenFlow encoding and decoding, ofpact formatting and parsing--were all found far away from each other. This often made it hard to see what was going on for a particular ofpact, since you had to search around to many different pieces of code. This commit reorganizes so that all of the code for a given ofpact is in a single place. As a code refactoring, this commit has little visible behavioral change. The update to ofproto-dpif.at illustrates one minor bug fix as a side effect: a flow that was added with the action "dec_ttl" (a standard OpenFlow action) was previously formatted as "dec_ttl(0)" (using a Nicira extension to specifically direct packets bounced to the controller because of too-low TTL), but after this commit it is correctly formatted as "dec_ttl". The other visible effect is to drop support for the Nicira extension dec_ttl action in OpenFlow 1.1 and later in favor of the equivalent standard action. It seems unlikely that anyone was really using the Nicira extension in OF1.1 or later. Signed-off-by: Ben Pfaff <blp@nicira.com> Acked-by: Jarno Rajahalme <jrajahalme@nicira.com>
* ofp-actions: Add instructions bitmaps and fix related bug.Ben Pfaff2014-08-112-8/+0
| | | | | | | | | | | | This will allow, later, to centralize all of the knowledge of instruction encoding inside ofp-actions. OFPIT11_ALL and OFPIT13_ALL are no longer used, so this commit removes them. Their definitions were wrong (they did not shift each bit into position correctly), so this commit is also a small bug fix.

* ofp-actions: Add action bitmap abstraction.Ben Pfaff2014-08-111-2/+10
| | | | | | | | | | | | | | | Until now, sets of actions have been abstracted separately outside ofp-actions, as enum ofputil_action_bitmap. Drawing sets of actions into ofp-actions, as done in this commit, makes for a better overall abstraction of actions, with better consistency. A big part of this commit is shifting from using ofp12_table_stats as if it were an abstraction for OpenFlow table stats, toward using a new struct ofputil_table_stats, which is what we generally do with other OpenFlow structures and fits better with the rest of the code.

* Do not seemingly #include Linux-specific headers on other platforms.Ben Pfaff2014-08-046-720/+13
| | | | | | | | | | | | | | | | | | Until now, the OVS source tree has had a whole maze of header files that make "#include <linux/openvswitch.h>" work OK regardless of platform, but this confuses everyone new to the tree, at first glance, and is difficult to understand at second glance too. This commit renames include/linux/openvswitch.h to datapath/linux/compat/include/linux/openvswitch.h without other change, then modifies the userspace build to generate a header that makes sense in portable Open vSwitch userspace from that header.

* datapath: Add support for Geneve tunneling.Jesse Gross2014-06-201-1/+2
| | | | | | | | | | | | | | | | | | | | | | This adds support for Geneve - Generic Network Virtualization Encapsulation. The protocol is documented at http://tools.ietf.org/html/draft-gross-geneve-00 The kernel implementation is completely agnostic to the options that are in use and can handle newly defined options without further work. It does this by simply matching on a byte array of options and allowing userspace to setup flows on this array. Userspace currently implements only support for basic version of Geneve. It can work with the base header (including the VNI) and is capable of parsing options but does not currently support any particular option definitions. Over time, the intention is to allow options to be matched through OpenFlow without requiring explicit support in OVS userspace.

| | | | | | | | | | | | | | | | Currently, the flow information that is matched for tunnels and the tunnel data passed around with packets is the same. However, as additional information is added this is not necessarily desirable, as in the case of pointers. This adds a new structure for tunnel metadata which currently contains only the existing struct. This change is purely internal to the kernel since the current OVS_KEY_ATTR_IPV4_TUNNEL is simply a compressed version of OVS_KEY_ATTR_TUNNEL that is translated at flow setup.
