* Permit to build OVS with only Python3 installedTimothy Redaelli2018-07-241-1/+2
| | | | | | | | | | | | | | | | | | This commit renames HAVE_PYTHON to HAVE_PYTHON2 and PYTHON to PYTHON2 and adds HAVE_PYTHON and PYTHON with a different semantics: - If PYTHON environment variable is set, use it as PYTHON - If a python2 interpreter is available, PYTHON became the python2 interpreter - If a python3 interpreter is available, PYTHON became the python3 interpreter PYTHON is only used to run the python scripts needed by the build system NOTE: Since currently most of the utilities and bugtool doesn't support Python3, they're installed only if python2 is available. This will be fixed in later commits. Signed-off-by: Timothy Redaelli <tredaelli@redhat.com> Signed-off-by: Ben Pfaff <blp@ovn.org>

* DNS: Add basic support for asynchronous DNS resolvingYifeng Sun2018-07-061-0/+1
| | | | | | | | | | | | | | | | | | | | | | 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.

* sparse: Add guards to prevent FreeBSD-incompatible #include order.Ben Pfaff2017-12-221-0/+1
| | | | | | | | | | FreeBSD insists that <sys/types.h> be included before <netinet/in.h> and that <netinet/in.h> be included before <arpa/inet.h>. This adds guards to the "sparse" headers to yield a warning if this order is violated. This commit also adjusts the order of many #includes to suit this requirement.

* 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.
