datapath: Tolerate backporting of rtnl_link_stats64 (as in RHEL 6). 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.

Raise minimum Autoconf version to 2.64. 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. Reported-by: Andy Southgate <andy.southgate@citrix.com>

Use Autotest for the Open vSwitch test suite. Autotest doesn't provide a lot of benefit by itself but it does allow us to easily put a wrapper around each test by using a macro to invoke it. (To do that with the built-in Automake test framework you need to write or generate a separate wrapper script for each test, which is a pain.) The next commit will take advantage of this possibility by adding support for code coverage analysis.

debian: Check for accurate Debian changelog version at build time too. 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.

docs: Only regenerate vswitch.pic when the schema really changes. Until now, vswitch.pic has been rebuilt whenever the schema changed.

OVS_CHECK_IF_PACKET
Fix glibc 2.7 strtok_r() bug in a more permanent fashion. The glibc 2.7 headers contain a bug that causes strtok_r() to segfault in some circumstances. Until now, we have been working around this problem at each invocation, but this depends on the programmer to remember to do so each time. This commit instead adds a shim that adds a work-around to the string.h header itself, so that it is much more difficult to miss the workaround.

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. Bug #2535.

Remove --disable-userspace "configure" option, since it breaks "make dist". I had thought that Automake was smart enough to ignore conditionals around EXTRA_DIST, so that all files always got distributed regardless of whether Automake conditionals were set. I was wrong. This commit removes the --disable-userspace option to "configure", which put a conditional around most of Makefile.am and thus unintentionally caused most of the distribution to be left out if --disable-userspace was specified. The alternative (fixing --disable-userspace) seems like too much work--it would require pushing "if ENABLE_USERSPACE" down into lots of subdirectory--and would be difficult to maintain.

backtrace: Make backtrace_capture() work on more systems. 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.

vlog: Make the vlog module catalog program-specific. 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.

Add InMon's sFlow Agent library to the build system. The C source and header files added in this commit is covered under the InMon sFlow license at http://www.inmon.com/technology/sflowlicense.txt The library requires -Wno-unused to compile without warnings, so this commit adds that for building the sFlow code only. Automake can only change compiler flags on a per-library or per-program basis, so sFlow is built as a separate library. The library will be used in upcoming commits.

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."
