We want datapath-protocol.h to be acceptable as a Linux kernel header, so
it must use Linux kernel types and must not have references to Open vSwitch
symbols or header files. This commit primarily makes that change to
datapath-protocol.h.
At the same time, at least for now we also want datapath-protocol.h to be
usable on non-Linux platforms, so we need some kind of compatiblity. Thus,
this commit also introduces a <linux/types.h> header file that defines the
necessary Linux kernel types on non-Linux platforms.
In turn, this requires openvswitch/types.h to use the Linux types directly
for ovs_be<N>; otherwise, sparse complains because now __be<N> and
ovs_be<N> are incompatible from its perspective, so this commit makes that
change too.
I don't have a non-Linux kernel platform readily available, so I only
tested the non-Linux part of the linux/types.h substitute by forcing that
case to be triggered with #if 0. It worked, except for errors in actual
Linux kernel headers included explicitly from OVS source files, so I think
it's likely to work in practice.
Bug #7559.

Currently ovs is using device stats for Linux devices and count them
itself in other situations. This leads to overlap with hardware stats,
inconsistencies, etc. It's much better to just always count the packets
flowing through the switch and let userspace do any merging that it wants.
Following patch removes vport->get_stats() interface. vport-stat is changed
to use new `struct ovs_vport_stat` rather than rtnl_link_stats64.
Definitions of rtnl_link_stats64 is removed from OVS. dipf_port->stat is also
removed as aggregate stats are only available at netdev layer.

This should catch future nroff syntax errors immediately, instead of much
later.

When development for a new long-term release is started, we haven't
typically updated the version string. This means that version numbers
used in binaries generated on this branch tend to lag behind "current"
stable releases. We considered using a "pre" string in the version
(eg, "1.2.0-pre1") but this causes some pain for RPMs. Instead, we
will now use "90" as the version's bug-fix number to indicate that this
will form a new release.
For example, the current stable series is "1.1.x" in the "branch-1.1"
branch, so the master branch will be labeled "1.1.90" in anticipation
that it will be the basis for the "1.2.x" series. Code in "branch-1.1"
will have the expected version numbers (ie, 1.1.0, 1.1.1, 1.1.2, etc)
and versions in-branch will lag slightly before an official release.

All of the xen-bugtool plugins that OVS has previously installed only under
XenServer are equally useful with Debian and other distributions, so
this commit installs and uses them everywhere.

The linux-2.6 and compat-2.6 directories apply equally to the upcoming
Linux 3.0 release, so this drops the 2.6 suffix and updates Makefiles.

OVS used to support Linux 2.4 and Linux 2.6, but now it only supports
Linux 2.6. Linux 3.0 is coming up, and it's just an evolution of 2.6, so
OVS should stop referring to it as "2.6".
This takes a first step by removing "26" from internal variable names.
There should be no user-visible changes.

The C=1 convention matches the kernel's convention, so running "make C=1"
will now get sparse results for both userspace and kernel compiles.

The backtrace_capture() implementation only worked properly with GNU C on
systems that have a simple stack frame with a frame pointer. Notably,
the x86-64 ABI by default has no frame pointer, so this failed on x86-64.
However, glibc has a function named backtrace() that does what we want.
This commit tests for this function and uses it when it is present, fixing
x86-64 backtraces.

-Werror is useful for development, but it screws up configure because it's
impossible to guess what new warnings compilers will add in the future.
This commit adds a new configure option to add CFLAGS after the configure
checks are done.
The use of AC_CONFIG_COMMANDS_PRE is based on Eric Blake's suggestion on
the autoconf mailing list: "AC_CONFIG_COMMANDS_PRE probably fits the bill
as the ideal macro to use for guaranteeing that you inject your shell code
at the last possible moment."

Red Hat Enterprise Linux 6 has a 2.6.32 kernel but it backports the
rtnl_link_stats64 structure that was introduced in 2.6.35, so we need to
check whether it was defined instead of just guessing based on the kernel
version number.
Build-tested only, on 2.6.32-71.14.1.el6 (RHEL 6),
linux-2.6.18-128.1.6.el5.xs5.5.0.496.101 (XenServer 5.5.0),
2.6.18-128.1.6.el5.xs5.5.0.505.1024xen (XenServer 5.5.0 update 1),
and upstream 2.6.18, 2.6.26, 2.6.29, 2.6.33, 2.6.34, 2.6.36, all for i386,
plus 2.6.36 for x86-64.
My machine's userspace headers have <linux/if_link.h> but not
rtnl_link_stats64. Jesse Gross tested the case where <linux/if_link.h>
has rtnl_link_stats64, on Ubuntu 10.10.

Until now, vswitch.pic has been rebuilt whenever the schema changed. This
is OK when the E-R diagram would really change, but many changes to the
schema don't change the E-R diagram, and it surprises people when
vswitch.pic changes in such a situation. This commit fixes the problem.

This is intended to provide controllers enough information to determine
whether a switch is overloaded or busted, to enable them to spread load
fairly across a group of switches.

These utilities were useful when Nicira was building switches with 16x2 LCD
front panel displays, but they aren't useful for other environments and
even Nicira does not use that kind of switch any longer. So remove them
and all the build infrastructure on which they depended.

With GCC -Wno-unused by itself isn't enough to avoid "unused parameter"
warnings, since we also use -Wunused-parameter. We also need to check for
and use -Wno-unused-parameter.

Until now, the collection of vlog modules supported by a given OVS program
was not specific to that program. That means that, for example, even
though ovs-dpctl does not have anything to do with jsonrpc, it still has
a vlog module for it. This is confusing, at best.
This commit fixes the problem on some systems, in particular on ones that
use GCC and the GNU linker. It uses the feature of the GNU linker
described in its manual as:
If an orphaned section's name is representable as a C identifier then
the linker will automatically see PROVIDE two symbols: __start_SECNAME
and __end_SECNAME, where SECNAME is the name of the section. These
indicate the start address and end address of the orphaned section
respectively.
Systems that don't support these features retain the earlier behavior.
This commit also fixes the annoyance that modifying lib/vlog-modules.def
causes all sources files that #include "vlog.h" to recompile.

When we increment the Open vSwitch version number, we tend to forget to
update it in debian/changelog at the same time. Right now this gets
fixed up automatically at "make dist" time, but it's even better if we can
always have it be correct in the repository. This commit should help with
that, by making both "make" and "make dist" refuse to proceed if the
version number is out of sync.

I've updated http://openvswitch.org/ovs-vswitchd.conf.db.5.pdf with

Most of the timekeeping needs of OVS are simply to measure intervals,
which means that it is sensitive to changes in the clock. This commit
replaces the existing clocks with monotonic timers. An additional set
of wall clock timers are added and used in locations that need absolute
time.

This merge is long overdue, simply because I forgot that there were
outstanding changes on "citrix" that had not yet been merged.
The important fix here is the addition of mlockall. This fixes some
bugs seen under stressful conditions in XenServer.

Commit 415f6c0b1 "stream-ssl: Make no-op reconfiguration cheap" caused
ovsdb-server to re-read its certificates and keys every 60 seconds just
in case they changed. However, doing this causes OpenSSL to drop its
connections. This commit solves the problem by making stream-ssl re-read
certificates and keys only if the files changed.

Our configure scripts were actually using Autoconf features introduced in
version 2.64 (e.g. AT_SKIP_IF, AT_CHECK_UNQUOTED), so we should not
claim 2.63 as prerequisite.

This module, which catches segmentation faults and prints a backtrace
before exiting, was useful for a while, but I believe that it has now
outlived its purpose. It is altogether better to have a core dump from
which one can extract much more information than a usually-poor backtrace,
and core dumps are much better integrated into a typical Unix system.
In addition, the "fault" module was of course not all that portable.
