* | ovn: Add initial design documentation.Ben Pfaff2015-02-261-1/+2
|/ | | | | | | | | | | | | | | | This commit adds preliminary design documentation for Open Virtual Network, or OVN, a new OVS-based project to add support for virtual networking to OVS, initially with OpenStack integration. This initial design has been influenced by many people, including (in alphabetical order) Aaron Rosen, Chris Wright, Gurucharan Shetty, Jeremy Stribling, Justin Pettit, Ken Duda, Kevin Benton, Kyle Mestery, Madhu Venugopal, Martin Casado, Natasha Gude, Pankaj Thakkar, Russell Bryant, Teemu Koponen, and Thomas Graf.

* configure.ac: Enable 'tar-pax' by defaultStephen Finucane2015-01-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Automake defaults to the 'v7' legacy tar format in GNU tar, through passing of the '-o' parameter to GNU tar. Enabling this option results in errors for users with 32 bit UIDs: $ make dist ... tardir=openvswitch-2.3.90 && ${TAR-tar} chof - "$tardir" | GZIP=--best gzip -c >openvswitch-2.3.90.tar.gz tar: value 12345678 out of uid_t range 0..2097151 tar: Exiting with failure status due to previous errors make[1]: Leaving directory `/development/ovs' ... The 'tar-pax' format is a 2001 POSIX standard that allow longer file names and other niceties. Its use is a configuration option in Automake 1.9+. Enable this option.

* vagrant: switch to use out of tree buildAndy Zhou2015-01-081-1/+0
| | | | | | | | | | | | | | | | Vagrant shared folder, at least on the default virtual box, does not support the creation of the socket files. If one were to build OVS under /vagrant, 'make check' would not work. Out of tree builds can be used to work around this issue. See Install.md for instructions. Since out of tree builds requires a clean source tree, Vagrantfile can not be a generated file. This commit removes Vagrantfile.in, commit Vagrantfile instead.

| | | | | | | | | | | | | | | This is a basic Vagrantfile which compiles and provisions the local OVS source tree in a Fedora 20 VM. The Vagrantfile.in can be extended to support additional distributions. To use this Vagrantfile: 1. Install Vagrant plus a compatible hypervisor 2. Run configure to translate Vagrantfile.in to Vagrantfile 3. Run `vagrant up` to create & provision the VM 4.

* Build: Add support for shared libraries and versioning.Scott Mann2014-11-111-1/+42
| | | | | | | | | | | | | | | | | These changes allow for the building of shared libraries by providing the --enable-shared option to configure. In particular, lib/libopenvwitch.so, lib/libsflow.so, ofproto/libofproto.so, and ovsdb/libovsdb.so will be built. Original behavior of building static remains the same. Additionally, versioning is introduced to each of the libraries objects paving the way for APIs to be built around them. A detailed comment outlining the rules for changing a version number is provided in configure.ac. Note that at this time, the version number is set to 1.0.0, no API is specified yet, and there are no requirements to maintain any sort of compatibility in any of the libraries.

* configure: Disable strict aliasing.Ben Pfaff2014-10-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The C standard allows compilers to do type-based alias analysis, which means that the compiler is allowed to assume that pointers to objects of different types are pointers to different objects. For example, a compiler may assume that "uint16_t *a" and "uint32_t *b" point to different and nonoverlapping locations because the pointed-to types are different. This can lead to surprising "optimizations" with compilers that by default do this kind of analysis, which includes GCC and Clang. The one escape clause that the C standard gives us is that character types must be assumed to alias any other object. We've always tried to use this escape clause to avoid problems with type-based alias analysis in the past. I think that we should continue to try to do this in the future. It's hard to tell what compiler we might want to use in the future, and one never knows what kind of control that compiler allows over alias analysis. However, recently I helped another developer debug a nasty and confusing issue, which turned out to be the result of a surprising compiler optimization due to alias analysis. I've seen enough of these that I don't think it's worthwhile to risk more problems than we have to. Thus, this commit turns off type-based alias analysis in GCC and Clang. Linus Torvalds thinks that type-base alias analysis is not sane, at least as GCC implements it: https://lkml.org/lkml/2003/2/26/158 The GCC manual says that -Wstrict-aliasing is only effective without -fno-strict-aliasing, otherwise I'd keep -Wstrict-aliasing also. Indications are that MSVC doesn't do type-based alias analysis by default. Signed-off-by: Ben Pfaff <blp@nicira.com> Acked-by: Jarno Rajahalme <jrajahalme@nicira.com>

* build: Allow building with autoconf 2.63Thomas Graf2014-06-271-1/+1
| | | | | | | | | | | | | | | | | | | | Reduces the dependency on autoconf from 2.64 to 2.63 to ease building on older platforms. There is only a few macros missing and they can be provided easily. A handful of tests needed modification. The difference in quoting behaviour between 2.63 and later require the m4_define() to be manually unfolded. The Debian control file is left untouched on purpose. The decision whether to adjust the dependency is left to the respective maintainers. Tested with autoconf 2.63 and 2.69.

* openvswitch: Use libtool and allow building shared libsHelmut Schaa2013-12-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | Currently openvswitch builds all libraries static only. However, libopenvswitch is linked into nearly all openvswitch executables making it hardly possible to run openvswitch on embedded devices (for example running OpenWrt). Convert openvswitch to use libtool for building its internal libs. This allows "--enable-shared" and "--enable-static" as configure arguments. Default is "--disable-shared" thus keeping the current behavior with the only change that static libs are installed by "make install". Since the openvswitch library interfaces are internal and thus not stable (yet) encode the openvswitch version into the library name: libopenvswitch-2.0.90.so Binary size is reduced to around 1/3 when using shared libs.
