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>

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.

stream-ssl: Only re-read certificates and keys if they change. 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. 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.

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.

OVS_CONDITIONAL_CC_OPTION([-Wno-unused-parameter], [HAVE_WNO_UNUSED_PARAMETER])
configure: Add option --enable-Werror to add -Werror to CFLAGS. -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."

AC_ARG_VAR(KARCH, [Kernel Architecture String])
AC_SUBST(KARCH)
datapath: Fix build with kernel header layout recently adopted by Debian. Recent Debian kernel-header packages divide kernel headers into two directories: the "common" headers that are not architecture-specific, which go in a directory named like /usr/src/kernel-headers-2.6.31-1-common, and architecture-specific headers in a directory named, e.g. /usr/src/kernel-headers-2.6.31-1-686. OVS needs to look at the ones in the "common" directory as part of its configuration process, but the build directory provided on --with-l26 is the architecture-specific directory. We also need the architecture-specific directory, since it is the one that we use as part of the "make", so we can't simply make the user specify the common directory on --with-l26. Furthermore, there is no easy-to-see link between the two directories, except as part of the text in a Makefile, which is not the easiest language to parse. This commit attempts to kluge around the problem by using the Debian directory naming. If the build directory does not contain the headers, then we replace the last component of its name by "-common" and check for the headers there. This is not ideal, but it does solve the actual problem at hand. Tested with Debian's linux-headers-2.6.31-1-686 and with a few older sets of headers that do not use this scheme.
