* compat: Add tc compatibility headers for old kernelsPaul Blakey2017-05-301-0/+1
| | | | | | | | | | | | | | Added compatibility headers for actions vlan and tunnel key. Do not use compat code when compiling kernel datapath there is no need for it as TC compatibility is not provided there. In other words, the compat code is only used when compiling user-space code against old kernel headers.

* configure: Reset libtool CURRENT version.Joe Stringer2017-05-171-1/+1
| | | | | | | | | | | | | | | | | Since commit f12e09b7b2e5 ("libopenvswitch: Rename to libfoo-X.Y."), the CURRENT libtool number is no longer derived from the OVS MINOR (from vMAJOR.MINOR.MICRO) version, so it can be reset to 0. Developers should attempt to avoid introducing ABI-breaking changes within a particular OVS-X.Y release series. Occasionally due to the nature of a particular bug, this is not possible. In such a case, developers must update the libtool CURRENT version to indicate this breakage to library users. In most OVS library releases, this is expected to remain 0.

* libX: add new release / version info tagsAaron Conole2017-01-181-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit uses the $PACKAGE_VERSION automake variable to construct a release and version info combination which sets the library name to be: libfoo-$(OVS_MAJOR_VERSION).so.$(OVS_MINOR_VERSION).0.$(OVS_MICRO_VERSION) where formerly, it was always: libfoo.so.1.0.0 This allows releases of Open vSwitch libraries to reflect which specific versions they came with, and sets up a psuedo ABI-versioning scheme. In this fashion, future releases of Open vSwitch could be installed alongside older releases, allowing 3rd party utilities linked against previous versions to continue to function. ex: $ ldd /path/to/utility linux-vdso.so.1 (0x00007ffe92cf6000) libopenvswitch-2.so.6 => /lib64/libopenvswitch-2.so.6 (0x00007f733b7a3000) libssl.so.10 => /lib64/libssl.so.10 (0x00007f733b530000) ...

* | ovn: Add ovn-ctl to assist with OVN daemon lifecycle.Russell Bryant2015-06-151-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces ovn-ctl, which is similar to ovs-ctl. I opted for a new script as everything in OVN so far is nicely isolated, so a new script seemed to make the most sense. If you'd like to run ovn-controller on a host already running ovs: # ovn-ctl start_controller If you'd like to run ovn-northd: # ovn-ctl start_northd Note that ovn-ctl assumes that ovn-northd is running on the same server as ovsdb-server hosting the OVN databases. Based on the current architecture this seems like a completely reasonable assumption. This can be improved later when needed. There's some additional stuff happening in start_northd to make the experience nicer and not require additional steps by the administrator. It creates the OVN dbs if they don't exist. If ovsdb-server hasn't loaded them, it tells it to load them, as well. ovn-ctl also supports running everything on the same host. This would be common in a test environment with a single host or small set of hosts. That would simply be: # ovs-ctl start --system-id=random # ovn-ctl start_northd # ovn-ctl start_controller Signed-off-by: Russell Bryant <rbryant@redhat.com> CC: Flavio Leitner <fbl@redhat.com> CC: Ben Pfaff <blp@nicira.com> [blp@nicira.com added configure.ac code to create ovn/utilities builddir] Signed-off-by: Ben Pfaff <blp@nicira.com>

| * configure: Stop avoiding -Wformat-zero-length.Ben Pfaff2015-06-101-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Debian likes to enable -Wformat-zero-length, even over our code trying to disable it. It isn't too hard to make our code warning-free against this option, so this commit both stops disabling it and fixes the warnings. The first fix is to change set_subprogram_name() to take a plain string instead of a format string, and to adjust its few callers. This fixes one warning since one of those callers passed in an empty string. The second fix is to remove a test for ovs_scan() against an empty string. I couldn't find a way to avoid a warning for this test, and it isn't too valuable in any case. This allows us to drop filtering for -Wformat from the Debian rules file, so this commit removes it.

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.

* 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>
