+Building DEB packages
+=====================
+
+REQUIREMENTS:
+ You will need a working Internet connection to execute the build, because
+ the build procedure for the included "dpdk" project attempts to contact the
+ Internet host "dpdk.org".
+
+There are three main parts to the process:
+ a) Stage the source tree so that dpkg-source will recognize its organization
+ and create a valid DSC source package for you;
+ b) Ensure that the tools required for building DEB packages are installed;
+ and
+ c) Launch the build.
+
+1) Create, or have on hand, a local clone of the git repository, with no
+untracked files or local modifications pending, up-to-date with the branch or
+commit reference from which you wish to construct the source release.
+
+The branch and repository origins will differ based on local conditions.
+
+Example:
+$ git clone -b master ssh://git@example.com:7999/~username/open-vpp
+
+("-b master" can be omitted since master is the default branch)
+
+2) Rename the checkout with a version number embedded in its name as is
+conventional for code releases. Again, your version number may vary.
+
+Example:
+$ mv open-vpp open-vpp-0.0.0
+
+3) Ensure that the dpkg-buildpackage program is installed.
+
+E.g.,
+
+# apt-get install dpkg-dev
+
+4) From the PARENT directory of the debian/ directory, run:
+
+$ cd open-vpp-0.0.0
+$ dpkg-buildpackage -I .git -us -uc
+
+(The -us and -uc flags omit GPG signatures from the .dsc and .changes files,
+respectively. You can add them later, or if you are preparing a signed release
+and have the signing key on hand, leave off the flags.)
+
+5) Get rid of the source directory; you now either have a source package with
+which you can re-create it at any time, or there were problems with the build,
+and you should go back to your git checkout to fix them.
+
+$ rm -r open-vpp-0.0.0
+
+END

+To run vpp with the debug shell:
+
+sudo vpe unix interactive
+
+which will result in a prompt that looks like:
+
+DBGvpd#
+
+To give it a spin, we can create a tap interface and try a simple ping
+(with trace).
+
+To create the tap:
+
+DBGvpd# tap connect foobar
+Created tap-0 for Linux tap 'foobar'
+DBGvpd# show int
+
+To assign it an ip address (and 'up' the interface):
+
+DBGvpd# set int ip address tap-0 192.168.1.1/24
+DBGvpd# set int state tap-0 up
+
+To turn on packet tracing for the tap interface:
+DBGvpd# trace add tapcli-rx 10
+
+Now, to set up and try the other end from the unix prompt:
+vagrant@vagrant-ubuntu-trusty-64:~$ sudo ip addr add 192.168.1.2/24 dev foobar
+vagrant@vagrant-ubuntu-trusty-64:~$ ping -c 3 192.168.1.1
+
+To look at the trace, back in the vpp CLI:
+DBGvpd# show trace
+
+And to stop tracing:
+
+DBGvpd# clear trace
+
+Other fun things to look at:
+
+The vlib packet processing graph:
+DBGvpd# show vlib graph
+
+which will produce output like:
+
+ Name Next Previous
+ip4-icmp-input error-punt [0] ip4-local
+ ip4-icmp-echo-request [1]
+ vpe-icmp4-oam [2]
+
+To read this, the first column (Name) is the name of the node.
+The second column (Next) is the name of the children of that node.
+The third column (Previous) is the name of the parents of this node.

+To run vpp with the debug shell:
+
+sudo ~vagrant/git/vpp/build-root/install-vpp_debug-native/vpp/bin/vpe unix interactive
+
+which will result in a prompt that looks like:
+
+DBGvpd#
+
+To give it a spin, we can create a tap interface and try a simple ping
+(with trace).
+
+To create the tap:
+
+DBGvpd# tap connect foobar
+Created tap-0 for Linux tap 'foobar'
+DBGvpd# show int
+
+To assign it an ip address (and 'up' the interface):
+
+DBGvpd# set int ip address tap-0 192.168.1.1/24
+DBGvpd# set int state tap-0 up
+
+To turn on packet tracing for the tap interface:
+DBGvpd# trace add tapcli-rx 10
+
+Now, to set up and try the other end from the unix prompt:
+vagrant@vagrant-ubuntu-trusty-64:~$ sudo ip addr add 192.168.1.2/24 dev foobar
+vagrant@vagrant-ubuntu-trusty-64:~$ ping -c 3 192.168.1.1
+
+To look at the trace, back in the vpp CLI:
+DBGvpd# show trace
+
+And to stop tracing:
+
+DBGvpd# clear trace
+
+Other fun things to look at:
+
+The vlib packet processing graph:
+DBGvpd# show vlib graph
+
+which will produce output like:
+
+ Name Next Previous
+ip4-icmp-input error-punt [0] ip4-local

+Subject: [PATCH 1/9] kni: fix igb build with kernel 4.2
+
+Kernel 4.2 has introduced two new parameters in ndo_bridge_getlink,
+which breaks DPDK compilation.
+
+Linux: 7d4f8d87 ("switchdev: ad VLAN support for ports bridge-getlink")
+
+This patch adds the necessary checks to fix it.

+
+Otherwise, /var/log/syslog eventually fills the disk. The error
+condition seems only to affect ESXi VM's. It'd be worth suggesting log
+throttling to the DPDK community. Much better to avoid making syslog
+(...) calls in the first place.

+# These exist entirely to fool aclocal when bootstrapping libtool.
+#
+# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
+# which have later been changed to m4_define as they aren't part of the
+# exported API, or moved to Autoconf or Automake where they belong.
+#
+# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
+# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)
+#
+# So we provide this file, which has a silly filename so it's always
+# included after everything else. This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
+# Yes, that means every name once taken will need to remain here until
+# we give up compatibility with versions before 1.7, at which point
+# we need to keep only those names which we still refer to.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an

+# One issue with vendor 'install' (even GNU) is that you can't

+# is unlikely to handle the host's binaries.
+# Fortunately install-sh will honor a STRIPPROG variable, so we
+# always use install-sh in "make install-strip", and initialize
+# STRIPPROG with the value of the STRIP variable (set by the user).

+\`configure' configures sample_plugin 1.0 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
+ --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]

+ --with-sysroot=DIR Search for dependent libraries within DIR
+ (or the compiler's sysroot if not specified).
+ --with-plugin-toolkit build using the vpp toolkit
+
+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ CPP C preprocessor
+ CCAS assembler compiler command (defaults to CC)
+ CCASFLAGS assembler compiler flags (defaults to CFLAGS)
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+# serial 5 lt~obsolete.m4
+
+# These exist entirely to fool aclocal when bootstrapping libtool.
+#
+# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
+# which have later been changed to m4_define as they aren't part of the
+# exported API, or moved to Autoconf or Automake where they belong.
+#
+# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
+# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)
+#
+# So we provide this file, which has a silly filename so it's always
+# included after everything else. This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
+# Yes, that means every name once taken will need to remain here until
+# we give up compatibility with versions before 1.7, at which point
+# we need to keep only those names which we still refer to.
+
+# This is to help aclocal find these macros, as it can't see m4_define.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH. The drawback is that using absolute paths prevent a
+# configured tree to be moved without reconfiguration.

+\`configure' configures svm 1.0 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
+ --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
+ --localstatedir=DIR modifiable single-machine data [PREFIX/var]

+ --with-pic[=PKGS] try to use only PIC/non-PIC objects [default=use
+ both]
+ --with-gnu-ld assume the C compiler uses GNU ld [default=no]
+ --with-sysroot=DIR Search for dependent libraries within DIR
+ (or the compiler's sysroot if not specified).
+
+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ CCAS assembler compiler command (defaults to CC)
+ CCASFLAGS assembler compiler flags (defaults to CFLAGS)
+ CPP C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.
+
+Report bugs to the package provider.

+# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.

+\`configure' configures vlibapi 1.0 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]

+ --with-gnu-ld assume the C compiler uses GNU ld [default=no]
+ --with-sysroot=DIR Search for dependent libraries within DIR
+ (or the compiler's sysroot if not specified).
+
+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ CPP C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+# Usage: $progname [OPTION]... [MODE-ARG]...
+#
+# Provide generalized library-building support services.
+#
+# --config show all configuration variables
+# --debug enable verbose shell tracing
+# -n, --dry-run display commands without modifying any files
+# --features display basic configuration information and exit
+# --mode=MODE use operation mode MODE
+# --preserve-dup-deps don't remove duplicate dependency libraries
+# --quiet, --silent don't print informational messages
+# --no-quiet, --no-silent
+# print informational messages (default)
+# --no-warn don't display warning messages
+# --tag=TAG use configuration variables from tag TAG
+# -v, --verbose print more informational messages than default
+# --no-verbose don't print the extra informational messages
+# --version print version information
+# -h, --help, --help-all print short, long, or detailed help message
+#
+# MODE must be one of the following:
+#
+# clean remove files from the build directory
+# compile compile a source file into a libtool object
+# execute automatically set library path, then run a program
+# finish complete the installation of libtool libraries
+# install install libraries or executables
+# link create a library or an executable
+# uninstall remove libraries from an installed directory
+#
+# MODE-ARGS vary depending on the MODE. When passed as first option,
+# `--mode=MODE' may be abbreviated as `MODE' or a unique abbreviation of that.
+# Try `$progname --help --mode=MODE' for a more detailed description of MODE.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an

+\`configure' configures vlib 1.1 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+

+ *
+ * If an application calls vlib_load_new_plugins() -- possibly after

+ * flexibility in terms of adding feature code or fixing bugs without
+ * requiring the data-plane process to restart.
+ *
+ * When the plugin mechanism loads a plugin, it uses dlsym to locate
+ * and call the plugin's function vlib_plugin_register() if it exists.
+ * A plugin which expects to be loaded after the vlib application
+ * starts uses this callback to modify the application. If vlib_plugin_register
+ * returns non-zero, the plugin mechanism dlclose()'s the plugin.
+ *
+ * Applications control the plugin search path and name filter by
+ * declaring the variables vlib_plugin_path and vlib_plugin_name_filter.
+ * libvlib_unix.la supplies weak references for these symbols which
+ * effectively disable the scheme. In order for the elf-section magic to
+ * work, static plugins must be loaded at the earliest possible moment.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH. The drawback is that using absolute paths prevent a
+# configured tree to be moved without reconfiguration.

+\`configure' configures vnet 1.1 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
+ --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
+ --localstatedir=DIR modifiable single-machine data [PREFIX/var]
+ --libdir=DIR object code libraries [EPREFIX/lib]
+ --includedir=DIR C header files [PREFIX/include]
+ --oldincludedir=DIR C header files for non-gcc [/usr/include]
+ --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
+ --datadir=DIR read-only architecture-independent data [DATAROOTDIR]
+ --infodir=DIR info documentation [DATAROOTDIR/info]
+ --localedir=DIR locale-dependent data [DATAROOTDIR/locale]

+ --with-gnu-ld assume the C compiler uses GNU ld [default=no]
+ --with-sysroot=DIR Search for dependent libraries within DIR
+ (or the compiler's sysroot if not specified).
+ --with-dpdk Use the Intel dpdk
+ --with-virl Compile for virl citizenship
+
+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ CPP C preprocessor
+ CCAS assembler compiler command (defaults to CC)
+ CCASFLAGS assembler compiler flags (defaults to CFLAGS)
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.
+
+Report bugs to the package provider.

+=== vnet classifier theory of operation ===
+
+The vnet classifier trades off simplicity and perf / scale
+characteristics. At a certain level, it's a dumb robot. Given an
+incoming packet, search an ordered list of (mask, match) tables. If
+the classifier finds a matching entry, take the indicated action. If
+not, take a last-resort action.
+
+We use the MMX-unit to match or hash 16 octets at a time. For hardware
+backward compatibility, the code does not [currently] use 256-bit
+(32-octet) vector instructions.
+
+Effective use of the classifier centers around building table lists
+which "hit" as soon as practicable. In many cases, established
+sessions hit in the first table. In this mode of operation, the
+classifier easily processes multiple MPPS / core - even with millions
+of sessions in the data base. Searching 357 tables on a regular basis
+will neatly solve the halting problem.
+
+==== Basic operation ====
+
+The classifier mask-and-match operation proceeds as follows. Given a
+starting classifier table index, lay hands on the indicated mask
+vector. When building tables, we arrange for the mask to obey
+mmx-unit (16-octet) alignment.
+
+We know that the first octet of packet data starts on a cache-line
+boundary. Further, it's reasonably likely that folks won't want to use
+the generalized classifier on the L2 header; preferring to decode the
+Ethertype manually. That scheme makes it easy to select among ip4 /
+ip6 / MPLS, etc. classifier table sets.
+
+A no-vlan-tag L2 header is 14 octets long. A typical ipv4 header
+begins with the octets 0x4500: version=4, header_length=5, DSCP=0,
+ECN=0. If one doesn't intend to classify on (DSCP, ECN) - the typical
+case - we program the classifier to skip the first 16-octet vector.
+
+To classify untagged ipv4 packets on source address, we program the
+classifier to skip one vector, and mask-and-match one vector.
+
+The basic match-and-match operation looks like this:
+
+ switch (t->match_n_vectors)
+ {
+ case 1:
+ result = (data[0 + t->skip_n_vectors] & mask[0]) ^ key[0];
+ break;
+
+ case 2:
+ result = (data[0 + t->skip_n_vectors] & mask[0]) ^ key[0];
+ result |= (data[1 + t->skip_n_vectors] & mask[1]) ^ key[1];
+ break;
+
+ <etc>
+ }
+
+ result_mask = u32x4_zero_byte_mask (result);
+ if (result_mask == 0xffff)
+ return (v);
+
+Net of setup, it costs a couple of clock cycles to mask-and-match 16
+octets.
+
+At the risk of belaboring an obvious point, the control-plane
+'''must''' pay attention to detail. When skipping one (or more)
+vectors, masks and matches must reflect that decision. See
+.../vnet/vnet/classify/vnet_classify.c:unformat_classify_[mask|match]. Note
+that vec_validate (xxx, 13) creates a 14-element vector.
+
+==== Creating a classifier table ====
+
+To create a new classifier table via the control-plane API, send a
+"classify_add_del_table" message. The underlying action routine,
+vnet_classify_add_del_table(...), is located in
+.../vnet/vnet/classify/vnet_classify.c, and has the following
+prototype:
+
+ int vnet_classify_add_del_table (vnet_classify_main_t * cm,
+ u8 * mask,
+ u32 nbuckets,
+ u32 memory_size,
+ u32 skip,
+ u32 match,
+ u32 next_table_index,
+ u32 miss_next_index,
+ u32 * table_index,
+ int is_add)
+
+Pass cm = &vnet_classify_main if calling this routine directly. Mask,
+skip(_n_vectors) and match(_n_vectors) are as described above. Mask
+need not be aligned, but it must be match*16 octets in length. To
+avoid having your head explode, be absolutely certain that '''only'''
+the bits you intend to match on are set.
+
+The classifier uses thread-safe, no-reader-locking-required
+bounded-index extensible hashing. Nbuckets is the [fixed] size of the
+hash bucket vector. The algorithm works in constant time regardless of
+hash collisions, but wastes space when the bucket array is too
+small. A good rule of thumb: let nbuckets = approximate number of
+entries expected.
+
+At a signficant cost in complexity, it would be possible to resize the
+bucket array dynamically. We have no plans to implement that function.
+
+Each classifier table has its own clib mheap memory allocation
+arena. To pick the memory_size parameter, note that each classifier
+table entry needs 16*(1 + match_n_vectors) bytes. Within reason, aim a
+bit high. Clib mheap memory uses o/s level virtual memory - not wired
+or hugetlb memory - so it's best not to scrimp on size.
+
+The "next_table_index" parameter is as described: the pool index in
+vnet_classify_main.tables of the next table to search. Code ~0 to
+indicate the end of the table list. 0 is a valid table index!
+
+We often create classification tables in reverse order -
+last-table-searched to first-table-searched - so we can easily set
+this parameter. Of course, one can manually adjust the data structure
+after-the-fact.
+
+Specific classifier client nodes - for example,
+.../vnet/vnet/classify/ip_classify.c - interpret the "miss_next_index"
+parameter as a vpp graph-node next index. When packet classification
+fails to produce a match, ip_classify_inline sends packets to the
+indicated disposition. A classifier application might program this
+parameter to send packets which don't match an existing session to a
+"first-sign-of-life, create-new-session" node.
+
+Finally, the is_add parameter indicates whether to add or delete the
+indicated table. The delete case implicitly terminates all sessions
+with extreme prejudice, by freeing the specified clib mheap.
+
+==== Creating a classifier session ====
+
+To create a new classifier session via the control-plane API, send a
+"classify_add_del_session" message. The underlying action routine,
+vnet_classify_add_del_session(...), is located in
+.../vnet/vnet/classify/vnet_classify.c, and has the following
+prototype:
+
+int vnet_classify_add_del_session (vnet_classify_main_t * cm,
+ u32 table_index,
+ u8 * match,
+ u32 hit_next_index,
+ u32 opaque_index,
+ i32 advance,
+ int is_add)
+
+Pass cm = &vnet_classify_main if calling this routine directly. Table
+index specifies the table which receives the new session / contains
+the session to delete depending on is_add.
+
+Match is the key for the indicated session. It need not be aligned,
+but it must be table->match_n_vectors*16 octets in length. As a
+courtesy, vnet_classify_add_del_session applies the table's mask to
+the stored key-value. In this way, one can create a session by passing
+unmasked (packet_data + offset) as the "match" parameter, and end up
+with unconfusing session keys.
+
+Specific classifier client nodes - for example,
+.../vnet/vnet/classify/ip_classify.c - interpret the per-session
+hit_next_index parameter as a vpp graph-node next index. When packet
+classification produces a match, ip_classify_inline sends packets to
+the indicated disposition.
+
+ip4/6_classify place the per-session opaque_index parameter into
+vnet_buffer(b)->l2_classify.opaque_index; a slight misnomer, but
+anyhow classifier applications can send session-hit packets to
+specific graph nodes, with useful values in buffer metadata. Depending
+on the required semantics, we send known-session traffic to a certain
+node, with e.g. a session pool index in buffer metadata. It's totally
+up to the control-plane and the specific use-case.
+
+Finally, nodes such as ip4/6-classify apply the advance parameter as a
+[signed!] argument to vlib_buffer_advance(...); to "consume" a
+networking layer. Example: if we classify incoming tunneled IP packets
+by (inner) source/dest address and source/dest port, we might choose
+to decapsulate and reencapsulate the inner packet. In such a case,
+program the advance parameter to perform the tunnel decapsulation, and
+program next_index to send traffic to a node which uses
+e.g. opaque_index to output traffic on a specific tunnel interface.

+// - a set of the above subinterfaces, repeating for each id
+// in the range <min_id> to <max_id>
+//
+// In the following, exact-match semantics (i.e. the number of vlan tags on the
+// packet must match the number of tags in the configuration) are used only if
+// the keyword exact-match is present. Non-exact match is the default.
+//
+// <intf-name> <id> dot1q <outer_id> [exact-match]
+// - a subinterface with the name <intf-name>.<id>. The subinterface
+// is a single dot1q vlan with vlan id <outer_id>.
+//
+// <intf-name> <id> dot1q any [exact-match]
+// - a subinterface with the name <intf-name>.<id>. The subinterface
+// is a single dot1q vlan with any vlan id.
+//
+// <intf-name> <id> dot1q <outer_id> inner-dot1q <inner_id> [exact-match]
+// - a subinterface with the name <intf-name>.<id>. The subinterface
+// is a double dot1q vlan with outer vlan id <outer_id> and inner vlan id
+// <inner_id>.
+//
+// <intf-name> <id> dot1q <outer_id> inner-dot1q any [exact-match]
+// - a subinterface with the name <intf-name>.<id>. The subinterface
+// is a double dot1q vlan with outer vlan id <id> and any inner vlan id.
+//
+// <intf-name> <id> dot1q any inner-dot1q any [exact-match]
+//
+// - a subinterface with the name <intf-name>.<id>. The subinterface
+// is a double dot1q vlan with any outer vlan id and any inner vlan id.
+//
+// For each of the above CLI, there is a duplicate that uses the keyword
+// "dot1ad" in place of the first "dot1q". These interfaces use ethertype
+// 0x88ad in place of 0x8100 for the outer ethertype. Note that for double-
+// tagged packets the inner ethertype is always 0x8100. Also note that
+// the dot1q and dot1ad naming spaces are independent, so it is legal to
+// have both "Gig3/0/0.1 dot1q 100" and "Gig3/0/0.2 dot1ad 100". For example:
+//
+// <intf-name> <id> dot1ad <outer_id> inner-dot1q <inner_id> [exact-match]
+// - a subinterface with the name <intf-name>.<id>. The subinterface
+// is a double dot1ad vlan with outer vlan id <outer_id> and inner vlan
+// id <inner_id>.
+//
+// <intf-name> <id> untagged
+// - a subinterface with the name <intf-name>.<id>. The subinterface
+// has no vlan tags. Only one can be specified per interface.
+//
+// <intf-name> <id> default
+// - a subinterface with the name <intf-name>.<id>. This is associated
+// with a packet that did not match any other configured subinterface
+// on this interface. Only one can be specified per interface.

+ * ip6 hop-by-hop option handling. We push pkts with h-b-h options to
+ * ip6_hop_by_hop_node_fn from ip6-lookup at a cost of ~2 clocks/pkt in
+ * the speed path.
+ *
+ * We parse through the h-b-h option TLVs, specifically looking for
+ * HBH_OPTION_TYPE_IOAM_DATA_LIST. [Someone needs to get bananas from
+ * IANA, aka to actually allocate the option TLV codes.]
+ *
+ * If we find the indicated option type, and we have remaining list
+ * elements in the trace list, allocate and populate the trace list
+ * element.
+ *
+ * At the ingress edge: punch in the h-b-h rewrite, then visit the
+ * standard h-b-h option handler. We have to be careful in the standard
+ * h-b-h handler, to avoid looping until we run out of rewrite space.
+ * Ask me how I know that.
+ *
+ * Remaining work:
+ * decide on egress point "pop and count" scheme
+ * time stamp handling: usec since the top of the hour?
+ * configure the node id
+ * trace list application data support
+ * cons up analysis / steering plug-in(s)
+ * add configuration binary APIs, vpe_api_test_support, yang models and
+ * orca code
+ * perf tune: dual loop, replace memcpy w/ N x 8-byte load/stores

+PORT NUMBERS
+
+(last updated 18 October 2005)
+
+The port numbers are divided into three ranges: the Well Known Ports,
+the Registered Ports, and the Dynamic and/or Private Ports.
+
+The Well Known Ports are those from 0 through 1023.
+
+The Registered Ports are those from 1024 through 49151
+
+The Dynamic and/or Private Ports are those from 49152 through 65535
+
+
+************************************************************************
+* PLEASE NOTE THE FOLLOWING: *
+* *
+* 1. UNASSIGNED PORT NUMBERS SHOULD NOT BE USED. THE IANA WILL ASSIGN *
+* THE NUMBER FOR THE PORT AFTER YOUR APPLICATION HAS BEEN APPROVED. *
+* *
+* 2. ASSIGNMENT OF A PORT NUMBER DOES NOT IN ANY WAY IMPLY AN *
+* ENDORSEMENT OF AN APPLICATION OR PRODUCT, AND THE FACT THAT NETWORK *
+* TRAFFIC IS FLOWING TO OR FROM A REGISTERED PORT DOES NOT MEAN THAT *
+* IT IS "GOOD" TRAFFIC. FIREWALL AND SYSTEM ADMINISTRATORS SHOULD *
+* CHOOSE HOW TO CONFIGURE THEIR SYSTEMS BASED ON THEIR KNOWLEDGE OF *
+* THE TRAFFIC IN QUESTION, NOT WHETHER THERE IS A PORT NUMBER *
+* REGISTERED OR NOT. *
+************************************************************************
+
+
+WELL KNOWN PORT NUMBERS
+
+The Well Known Ports are assigned by the IANA and on most systems can
+only be used by system (or root) processes or by programs executed by
+privileged users.
+
+Ports are used in the TCP [RFC793] to name the ends of logical
+connections which carry long term conversations. For the purpose of
+providing services to unknown callers, a service contact port is
+defined. This list specifies the port used by the server process as
+its contact port. The contact port is sometimes called the
+"well-known port".
+
+To the extent possible, these same port assignments are used with the
+UDP [RFC768].
+
+The range for assigned ports managed by the IANA is 0-1023.

+ * EFP filtering is a basic switch feature which prevents an interface from
+ * transmitting a packet that doesn't match the interface's ingress match
+ * criteria. The check has two parts, one performed before egress vlan tag
+ * rewrite and one after.
+ *
+ * The pre-rewrite check insures the packet matches what an ingress packet looks
+ * like after going through the interface's ingress tag rewrite operation. Only
+ * pushed tags are compared. So:
+ * - if the ingress vlan tag rewrite pushes no tags (or is not enabled),
+ * any packet passes the filter
+ * - if the ingress vlan tag rewrite pushes one tag,
+ * the packet must have at least one tag, and the outer tag must match the pushed tag
+ * - if the ingress vlan tag rewrite pushes two tags,
+ * the packet must have at least two tags, and the outer two tags must match the pushed tags
+ *
+ * The pre-rewrite check is performed in the l2-output node.
+ *
+ * The post-rewrite check insures the packet matches what an ingress packet looks
+ * like before going through the interface's ingress tag rewrite operation. It verifies
+ * that such a packet arriving on the wire at this port would be classified as arriving
+ * an input interface equal to the packet's output interface. This can be done by running
+ * the output packet's vlan tags and output port through the interface classification,
+ * and checking if the resulting interface matches the output interface.
+ *
+ * The post-rewrite check is performed here.

+ * General L2 / L3 cross-connect, used to set up
+ * "L2 interface <--> your-favorite-tunnel-encap" tunnels.
+ *
+ * We set up a typical L2 cross-connect or (future) bridge
+ * to hook L2 interface(s) up to the L3 stack in arbitrary ways.
+ *
+ * Each l2_xcrw adjacency specifies 3 things:
+ *
+ * 1. The next graph node (presumably in the L3 stack) to
+ * process the (L2 -> L3) packet
+ *
+ * 2. A new value for vnet_buffer(b)->sw_if_index[VLIB_TX]
+ * (i.e. a lookup FIB index),
+ *
+ * 3. A rewrite string to apply.
+ *
+ * Example: to cross-connect an L2 interface or (future) bridge
+ * to an mpls-o-gre tunnel, set up the L2 rewrite string as shown in
+ * mpls_gre_rewrite, and use "mpls-post-rewrite" to fix the
+ * GRE IP header checksum and length fields.

+Internet-Draft LISP Generic Protocol Extension July 2014
+
+
+1. Introduction
+
+ LISP [RFC6830] defines an encapsulation format that carries IPv4 or
+ IPv6 (henceforth referred to as IP) packets in a LISP header and
+ outer UDP/IP transport.
+
+ The LISP header does not specify the protocol being encapsulated and
+ therefore is currently limited to encapsulating only IP packet
+ payloads. Other protocols, most notably VXLAN [VXLAN] (which defines
+ a similar header format to LISP), are used to encapsulate L2
+ protocols such as Ethernet. LISP [RFC6830] can be extended to
+ indicate the inner protocol, enabling the encapsulation of Ethernet,
+ IP or any other desired protocol all the while ensuring compatibility
+ with existing LISP [RFC6830] deployments.
+
+ As LISP is deployed, there's also the need to provide increased
+ visibility and diagnostic capabilities within the overlay.
+
+ This document describes extending LISP ([RFC6830]) via the following
+ changes:
+
+ Next Protocol Bit (P bit): A reserved flag bit is allocated, and set
+ in the LISP-gpe header to indicate that a next protocol field is
+ present.
+
+ OAM Flag Bit (O bit): A reserved flag bit is allocated, and set in
+ the LISP-gpe header, to indicate that the packet is an OAM packet.
+
+ Version: Two reserved bits are allocated, and set in the LISP-gpe
+ header, to indicate LISP-gpe protocol version.
+
+ Next protocol: An 8 bit next protocol field is present in the LISP-
+ gpe header.

+
+
+2. LISP Header Without Protocol Extensions
+
+ As described in the introduction, the LISP header has no protocol
+ identifier that indicates the type of payload being carried by LISP.
+ Because of this, LISP is limited to an IP payload. Furthermore, the
+ LISP header has no mechanism to signal OAM packets.
+
+ The LISP header contains flags (some defined, some reserved), a
+ Nonce/Map-version field and an instance ID/Locator-status-bit field.
+ The flags provide flexibility to define how the reserved bits can be
+ used to change the definition of the LISP header.

+
+3. Generic Protocol Extension for LISP (LISP-gpe)
+
+3.1. Multi Protocol Support
+
+ This draft defines the following changes to the LISP header in order
+ to support multi-protocol encapsulation.
+
+ P Bit: Flag bit 5 is defined as the Next Protocol bit. The P bit
+ MUST be set to 1 to indicate the presence of the 8 bit next
+ protocol field.
+
+ P = 0 indicates that the payload MUST conform to LISP as defined
+ in [RFC6830].
+
+ Flag bit 5 was chosen as the P bit because this flag bit is
+ currently unallocated in LISP [RFC6830].
+
+ Next Protocol Field: The lower 8 bits of the first word are used to
+ carry a next protocol. This next protocol field contains the
+ protocol of the encapsulated payload packet.
+
+ LISP [RFC6830] uses the lower 16 bits of the first word for either
+ a nonce, an echo-nonce ([RFC6830]) or to support map-versioning
+ ([RFC6834]). These are all optional capabilities that are
+ indicated by setting the N, E, and the V bit respectively.
+
+ To maintain the desired data plane compatibility, when the P bit
+ is set, the N, E, and V bits MUST be set to zero.
+
+ A new protocol registry will be requested from IANA for the Next
+ Protocol field. This draft defines the following Next Protocol
+ values:
+
+ 0x1 : IPv4
+
+ 0x2 : IPv6
+
+ 0x3 : Ethernet
+
+ 0x4: Network Service Header

+3.2. OAM Support
+
+ Flag bit 7 is defined as the O bit. When the O bit is set to 1, the
+ packet is an OAM packet and OAM processing MUST occur. The OAM
+ protocol details are out of scope for this document. As with the
+ P-bit, bit 7 is currently a reserved flag in [RFC6830].

+
+
+4. Backward Compatibility
+
+ Undefined (in RFC6830) flag bits 5 and 7, LISP-gpe P and O bits, were
+ selected to ensure compatibility with existing LISP [RFC6830]
+ deployments.
+
+ Similarly, using P = 0 to indicate that the format of the header and
+ payload conforms to [RFC6830] ensures compatibility with existing
+ LISP hardware forwarding platforms.
+
+4.1. LISP-gpe Routers to (legacy) LISP Routers
+
+ A LISP-gpe router MUST not encapsulate non-IP packet nor OAM packets
+ to a LISP router. A method for determining the capabilities of a
+ LISP router (gpe or "legacy") is out of the scope of this draft.
+
+ When encapsulating IP packets to a LISP router the P bit SHOULD be
+ set to 1 and the UDP port MUST be set to 4341. OAM bit MUST be set
+ to 0. The Next Protocol field SHOULD be 0x1 (IPv4) or 0x2 (IPv6).
+ The (legacy) LISP router will ignore the P bit and the protocol type
+ field. The (legacy) LISP router will treat the packet as a LISP
+ packet and inspect the first nibble of the payload to determine the
+ IP version.
+
+ When the P bit is set, the N, E, and V bits MUST be set to zero. The
+ receiving (legacy) LISP router will ignore N, E and V bits, when the
+ P bit is set.
+
+4.2. (legacy) LISP Routers to LISP-gpe Routers
+
+ When a LISP-gpe router receives a packet from a (legacy) LISP router,
+ the P bit MUST not be set and the UDP port MUST be 4341. The payload
+ MUST be IP, and the LISP-gpe router will inspect the first nibble of
+ the payload to determine IP version.
+
+4.3. Type of Service
+
+ When a LISP-gpe router performs Ethernet encapsulation, the inner
+ 802.1Q [IEEE8021Q] priority code point (PCP) field MAY be mapped from
+ the encapsulated frame to the Type of Service field in the outer IPv4
+ header, or in the case of IPv6 the 'Traffic Class' field.
+
+4.4. VLAN Identifier (VID)
+
+ When a LISP-gpe router performs Ethernet encapsulation, the inner
+ header 802.1Q [IEEE8021Q] VLAN Identifier (VID) MAY be mapped to, or
+ used to determine the LISP Instance ID field.

+6. Security Considerations
+
+ LISP-gpe security considerations are similar to the LISP security
+ considerations documented at length in LISP [RFC6830]. With LISP-
+ gpe, issues such as dataplane spoofing, flooding, and traffic
+ redirection are dependent on the particular protocol payload
+ encapsulated.

+8. IANA Considerations
+
+ IANA is requested to set up a registry of "Next Protocol". These are
+ 8-bit values. Next Protocol values 0, 1, 2, 3 and 4 are defined in
+ this draft. New values are assigned via Standards Action [RFC5226].
+
+ +---------------+-------------+---------------+
+ | Next Protocol | Description | Reference |
+ +---------------+-------------+---------------+
+ | 0 | Reserved | This document |
+ | | | |
+ | 1 | IPv4 | This document |
+ | | | |
+ | 2 | IPv6 | This document |
+ | | | |
+ | 3 | Ethernet | This document |
+ | | | |
+ | 4 | NSH | This document |
+ | | | |
+ | 5..253 | Unassigned | |
+ +---------------+-------------+---------------+
+
+ Table 1
+
+ There are ten bits at the beginning of the LISP-gpe header. New
+ bits are assigned via Standards Action [RFC5226].
+
+ Bits 0-3 - Assigned by LISP [RFC6830]
+ Bit 4 - Instance ID (I bit)
+ Bit 5 - Next Protocol (P bit)
+ Bit 6 - Reserved
+ Bit 7 - OAM (O bit)
+ Bits 8-9 - Version

+# VPP MAP and Lw4o6 implementation
+
+This is a memo intended to contain documentation of the VPP MAP and Lw4o6 implementations.
+Everything that is not directly obvious should come here.
+
+
+
+## MAP-E Virtual Reassembly
+
+The MAP-E implementation supports handling of IPv4 fragments as well as IPv4-in-IPv6 inner and outer fragments. This is called virtual reassembly because the fragments are not actually reassembled. Instead, some meta-data are kept about the first fragment and reused for subsequent fragments.
+
+Fragment caching and handling is not always necessary. It is performed when:
+* An IPv4 fragment is received and the destination IPv4 address is shared.
+* An IPv6 packet is received with an inner IPv4 fragment, the IPv4 source address is shared, and 'security-check fragments' is on.
+* An IPv6 fragment is received.
+
+There are 3 dedicated nodes:
+* ip4-map-reass
+* ip6-map-ip4-reass
+* ip6-map-ip6-reass
+
+ip4-map sends all fragments to ip4-map-reass.
+ip6-map sends all inner-fragments to ip6-map-ip4-reass.
+ip6-map sends all outer-fragments to ip6-map-ip6-reass.
+
+IPv4 (resp. IPv6) virtual reassembly makes use of a hash table in order to store IPv4 (resp. IPv6) reassembly structures. The hash-key is based on the IPv4-src:IPv4-dst:Frag-ID:Protocol tuple (resp. IPv6-src:IPv6-dst:Frag-ID tuple, as the protocol is IPv4-in-IPv6). Therefore, each packet reassembly makes use of exactly one reassembly structure. When such a structure is allocated, it is timestamped with the current time. Finally, those structures are capable of storing a limited number of buffer indexes.
+
+An IPv4 (resp. IPv6) reassembly structure can cache up to MAP_IP4_REASS_MAX_FRAGMENTS_PER_REASSEMBLY (resp. MAP_IP6_REASS_MAX_FRAGMENTS_PER_REASSEMBLY) buffers. Buffers are cached until the first fragment is received.
+
+#### Virtual Reassembly configuration
+
+IPv4 and IPv6 virtual reassembly support the following configuration:
+ map params reassembly [ip4 | ip6] [lifetime <lifetime-ms>] [pool-size <pool-size>] [buffers <buffers>] [ht-ratio <ht-ratio>]
+
+lifetime:
+ The time in milliseconds a reassembly structure is considered valid. The longer, the more reliable is reassembly, but the more likely it is to exhaust the pool of reassembly structures. IPv4 standard suggests a lifetime of 15 seconds. IPv6 specifies a lifetime of 60 people. Those values are not realistic for high-throughput cases.
+
+buffers:
+ The upper limit of buffers that are allowed to be cached. It can be used to protect against fragmentation attacks which would aim to exhaust the global buffers pool.
+
+pool-size:
+ The number of reassembly structures that can be allocated. As each structure can store a small fixed number of fragments, it also sets an upper-bound of 'pool-size * MAP_IPX_REASS_MAX_FRAGMENTS_PER_REASSEMBLY' buffers that can be cached in total.
+
+ht-ratio:
+ The amount of buckets in the hash-table is pool-size * ht-ratio.
+
+
+Any time pool-size and ht-ratio is modified, the hash-table is destroyed and created again, which means all current state is lost.
+
+
+##### Additional considerations
+
+Reassembly at high rate is expensive in terms of buffers. There is a trade-off between the lifetime and number of allocated buffers. Reducing the lifetime helps, but at the cost of loosing state for fragments that are wide appart.
+
+Let:
+R be the packet rate at which fragments are received.
+F be the number of fragments per packet.
+
+Assuming the first fragment is always received last. We should have:
+buffers > lifetime * R / F * (F - 1)
+pool-size > lifetime * R/F
+
+This is a worst case. Receiving the first fragment earlier helps reducing the number of required buffers. Also, an optimization is implemented (MAP_IP6_REASS_COUNT_BYTES and MAP_IP4_REASS_COUNT_BYTES) which counts the number of transmitted bytes and remembers the total number of bytes which should be transmitted based on the last fragment, and therefore helps reducing 'pool-size'.
+
+But the formula shows that it is challenging to forward a significant amount of fragmented packets at high rates. For instance, with a lifetime of 1 second, 5Mpps packet rate would require buffering up to 2.5 millions fragments.
+
+If you want to do that, be prepared to configure a lot of fragments.

+ *
+ * Base Header Field Descriptions:
+ *
+ * Version: The version field is used to ensure backward compatibility
+ * going forward with future NSH updates.
+ *
+ * O bit: Indicates that this packet is an operations and management
+ * (OAM) packet. SFF and SFs nodes MUST examine the payload and take
+ * appropriate action (e.g. return status information).
+ *
+ * OAM message specifics and handling details are outside the scope of
+ * this document.
+ *
+ * C bit: Indicates that a critical metadata TLV is present (see section
+ * 7). This bit acts as an indication for hardware implementers to
+ * decide how to handle the presence of a critical TLV without
+ * necessarily needing to parse all TLVs present. The C bit MUST be set
+ * to 1 if one or more critical TLVs are present.
+ *
+ * All other flag fields are reserved.
+ *
+ * Length: total length, in 4 byte words, of the NSH header, including
+ * optional variable TLVs. Length must be equal or greater than 6.
+ *
+ * MD Type: indicates the format of NSH beyond the base header and the
+ * type of metadata being carried. This typing is used to describe the
+ * use for the metadata. A new registry will be requested from IANA for
+ * the MD Type. NSH defines one type, type = 0x1 which indicates that
+ * the format of the header is as per this draft.
+ *
+ * The format of the base header is invariant, and not described by MD
+ * Type.
+ *
+ * Next Protocol: indicates the protocol type of the original packet. A
+ * new IANA registry will be created for protocol type.
+ *
+ * This draft defines the following Next Protocol values:
+ *
+ * 0x1 : IPv4
+ * 0x2 : IPv6
+ * 0x3 : Ethernet

+Internet-Draft Generic Protocol Extension for VXLAN July 2014
+
+
+1. Introduction
+
+ Virtual eXtensible Local Area Network [VXLAN] defines an
+ encapsulation format that encapsulates Ethernet frames in an outer
+ UDP/IP transport. As data centers evolve, the need to carry other
+ protocols encapsulated in an IP packet is required, as well as the
+ need to provide increased visibility and diagnostic capabilities
+ within the overlay. The VXLAN header does not specify the protocol
+ being encapsulated and therefore is currently limited to
+ encapsulating only Ethernet frame payload, nor does it provide the
+ ability to define OAM protocols. Rather than defining yet another
+ encapsulation, VXLAN is extended to provide protocol typing and OAM
+ capabilities.
+
+ This document describes extending VXLAN via the following changes:
+
+ Next Protocol Bit (P bit): A reserved flag bit is allocated, and set
+ in the VXLAN-gpe header to indicate that a next protocol field is
+ present.
+
+ OAM Flag Bit (O bit): A reserved flag bit is allocated, and set in
+ the VXLAN-gpe header, to indicate that the packet is an OAM
+ packet.
+
+ Version: Two reserved bits are allocated, and set in the VXLAN-gpe
+ header, to indicate VXLAN-gpe protocol version.
+
+ Next Protocol: A 8 bit next protocol field is present in the VXLAN-
+ gpe header.

+
+
+2. VXLAN Without Protocol Extension
+
+ As described in the introduction, the VXLAN header has no protocol
+ identifier that indicates the type of payload being carried by VXLAN.
+ Because of this, VXLAN is limited to an Ethernet payload.
+ Furthermore, the VXLAN header has no mechanism to signal OAM packets.
+
+ The VXLAN header defines bits 0-7 as flags (some defined, some
+ reserved), the VXLAN network identifier (VNI) field and several
+ reserved bits. The flags provide flexibility to define how the
+ reserved bits can be used to change the definition of the VXLAN
+ header.

+
+3. Generic Protocol Extension VXLAN (VXLAN-gpe)
+
+3.1. Multi Protocol Support
+
+ This draft defines the following two changes to the VXLAN header in
+ order to support multi-protocol encapsulation:
+
+ P Bit: Flag bit 5 is defined as the Next Protocol bit. The P bit
+ MUST be set to 1 to indicate the presence of the 8 bit next
+ protocol field.
+
+ P = 0 indicates that the payload MUST conform to VXLAN as defined
+ in [VXLAN].
+
+ Flag bit 5 was chosen as the P bit because this flag bit is
+ currently reserved in VXLAN.
+
+ Next Protocol Field: The lower 8 bits of the first word are used to
+ carry a next protocol. This next protocol field contains the
+ protocol of the encapsulated payload packet. A new protocol
+ registry will be requested from IANA.
+
+ This draft defines the following Next Protocol values:
+
+ 0x1 : IPv4
+ 0x2 : IPv6
+ 0x3 : Ethernet
+ 0x4 : Network Service Header [NSH]

+
+
+3.2. OAM Support
+
+ Flag bit 7 is defined as the O bit. When the O bit is set to 1, the
+ packet is an OAM packet and OAM processing MUST occur. The OAM
+ protocol details are out of scope for this document. As with the
+ P-bit, bit 7 is currently a reserved flag in VXLAN.

+
+3.3. Version Bits
+
+ VXLAN-gpe bits 8 and 9 are defined as version bits. These bits are
+ reserved in VXLAN. The version field is used to ensure backward
+ compatibility going forward with future VXLAN-gpe updates.
+
+ The initial version for VXLAN-gpe is 0.

+
+
+4. Backward Compatibility
+
+4.1. VXLAN VTEP to VXLAN-gpe VTEP
+
+ As per VXLAN, reserved bits 5 and 7, VXLAN-gpe P and O-bits
+ respectively must be set to zero. The remaining reserved bits must
+ be zero, including the VXLAN-gpe version field, bits 8 and 9. The
+ encapsulated payload MUST be Ethernet.
+
+4.2. VXLAN-gpe VTEP to VXLAN VTEP
+
+ A VXLAN-gpe VTEP MUST NOT encapsulate non-Ethernet frames to a VXLAN
+ VTEP. When encapsulating Ethernet frames to a VXLAN VTEP, the VXLAN-
+ gpe VTEP will set the P bit to 0, the Next Protocol to 0 and use UDP
+ destination port 4789. A VXLAN-gpe VTEP MUST also set O = 0 and Ver
+ = 0 when encapsulating Ethernet frames to VXLAN VTEP. The receiving
+ VXLAN VTEP will threat this packet as a VXLAN packet.
+
+ A method for determining the capabilities of a VXLAN VTEP (gpe or
+ non-gpe) is out of the scope of this draft.
+
+4.3. VXLAN-gpe UDP Ports
+
+ VXLAN-gpe uses a new UDP destination port (to be assigned by IANA)
+ when sending traffic to VXLAN-gpe VTEPs.
+
+4.4. VXLAN-gpe and Encapsulated IP Header Fields
+
+ When encapsulating and decapsulating IPv4 and IPv6 packets, certain
+ fields, such as IPv4 Time to Live (TTL) from the inner IP header need
+ to be considered. VXLAN-gpe IP encapsulation and decapsulation
+ utilizes the techniques described in [RFC6830], section 5.3.

+6. Security Considerations
+
+ VXLAN's security is focused on issues around L2 encapsulation into
+ L3. With VXLAN-gpe, issues such as spoofing, flooding, and traffic
+ redirection are dependent on the particular protocol payload
+ encapsulated.

+8. IANA Considerations
+
+8.1. UDP Port
+
+ A new UDP port will be requested from IANA.
+
+8.2. VXLAN-gpe Next Protocol
+
+ IANA is requested to set up a registry of "Next Protocol". These are
+ 8-bit values. Next Protocol values 0, 1, 2, 3 and 4 are defined in
+ this draft. New values are assigned via Standards Action [RFC5226].
+
+ +---------------+-------------+---------------+
+ | Next Protocol | Description | Reference |
+ +---------------+-------------+---------------+
+ | 0 | Reserved | This document |
+ | | | |
+ | 1 | IPv4 | This document |
+ | | | |
+ | 2 | IPv6 | This document |
+ | | | |
+ | 3 | Ethernet | This document |

+ | 4 | NSH | This document |
+ | | | |
+ | 5..253 | Unassigned | |
+ +---------------+-------------+---------------+
+
+ Table 1
+
+8.3. VXLAN-gpe Reserved Bits
+
+ There are ten bits at the beginning of the VXLAN-gpe header. New
+ bits are assigned via Standards Action [RFC5226].
+
+ Bits 0-3 - Reserved
+ Bit 4 - Instance ID (I bit)
+ Bit 5 - Next Protocol (P bit)
+ Bit 6 - Reserved
+ Bit 7 - OAM (O bit)
+ Bits 8-9 - Version

+// 16usec (8Ghz CPU) and 131usec (1Ghz CPU).
+// The token_per_period computation takes into account the clock speed.
+//
+// The 32-bit bucket/limit supports about 850ms of burst on a 40GE port,
+// or 340ms on a 100GE port. If a larger burst is configued, then the

+// more than that, the bucket and limit fields could be expanded.
+//
+// tokens_per_period should be > 1000 to support 0.1% granularity.
+// To support lower rates (which would not meet this requirement), the packet
+// length, bucket, and limit values can be scaled. The scale is a power of 2
+// so the multiplication can be implemented as a shift. The control plane
+// computes the shift amount be the largest possible that still supports the

+ IPv6 Segment Routing Header (SRH)
+ draft-previdi-6man-segment-routing-header-05
+
+Abstract
+
+ Segment Routing (SR) allows a node to steer a packet through a
+ controlled set of instructions, called segments, by prepending a SR
+ header to the packet. A segment can represent any instruction,
+ topological or service-based. SR allows to enforce a flow through
+ any path (topological, or application/service based) while
+ maintaining per-flow state only at the ingress node to the SR domain.
+
+ Segment Routing can be applied to the IPv6 data plane with the
+ addition of a new type of Routing Extension Header. This draft
+ describes the Segment Routing Extension Header Type and how it is
+ used by SR capable nodes.

+3. Introduction
+
+ Segment Routing (SR), defined in
+ [I-D.filsfils-spring-segment-routing], allows a node to steer a
+ packet through a controlled set of instructions, called segments, by
+ prepending a SR header to the packet. A segment can represent any
+ instruction, topological or service-based. SR allows to enforce a
+ flow through any path (topological or service/application based)
+ while maintaining per-flow state only at the ingress node to the SR
+ domain. Segments can be derived from different components: IGP, BGP,
+ Services, Contexts, Locators, etc. The list of segment forming the
+ path is called the Segment List and is encoded in the packet header.

+Internet-Draft IPv6 Segment Routing Header (SRH) December 2014
+
+
+ SR allows the use of strict and loose source based routing paradigms
+ without requiring any additional signaling protocols in the
+ infrastructure hence delivering an excellent scalability property.
+
+ The source based routing model described in
+ [I-D.filsfils-spring-segment-routing] is inherited from the ones
+ proposed by [RFC1940] and [RFC2460]. The source based routing model
+ offers the support for explicit routing capability.
+
+3.1. Data Planes supporting Segment Routing
+
+ Segment Routing (SR), can be instantiated over MPLS
+ ([I-D.filsfils-spring-segment-routing-mpls]) and IPv6. This document
+ defines its instantiation over the IPv6 data-plane based on the use-
+ cases defined in [I-D.ietf-spring-ipv6-use-cases].
+
+ Segment Routing for IPv6 (SR-IPv6) is required in networks where MPLS
+ data-plane is not used or, when combined with SR-MPLS, in networks
+ where MPLS is used in the core and IPv6 is used at the edge (home
+ networks, datacenters).
+
+ This document defines a new type of Routing Header (originally
+ defined in [RFC2460]) called the Segment Routing Header (SRH) in
+ order to convey the Segment List in the packet header as defined in
+ [I-D.filsfils-spring-segment-routing]. Mechanisms through which
+ segment are known and advertised are outside the scope of this
+ document.
+
+3.2. Illustration
+
+ In the context of Figure 1 where all the links have the same IGP
+ cost, let us assume that a packet P enters the SR domain at an
+ ingress edge router I and that the operator requests the following
+ requirements for packet P:
+
+ The local service S offered by node B must be applied to packet P.
+
+ The links AB and CE cannot be used to transport the packet P.
+
+ Any node N along the journey of the packet should be able to
+ determine where the packet P entered the SR domain and where it
+ will exit. The intermediate node should be able to determine the
+ paths from the ingress edge router to itself, and from itself to
+ the egress edge router.
+
+ Per-flow State for packet P should only be created at the ingress
+ edge router.

+
+
+ The operator can forbid, for security reasons, anyone outside the
+ operator domain to exploit its intra-domain SR capabilities.

+ Figure 1: An illustration of SR properties
+
+ All these properties may be realized by instructing the ingress SR
+ edge router I to push the following abstract SR header on the packet
+ P.
+
+ +---------------------------------------------------------------+
+ | | |
+ | Abstract SR Header | |
+ | | |
+ | {SD, SB, SS, SF, SE}, Ptr, SI, SE | Transported |
+ | ^ | | Packet |
+ | | | | P |
+ | +---------------------+ | |
+ | | |
+ +---------------------------------------------------------------+
+
+ Figure 2: Packet P at node I
+
+ The abstract SR header contains a source route encoded as a list of
+ segments {SD, SB, SS, SF, SE}, a pointer (Ptr) and the identification
+ of the ingress and egress SR edge routers (segments SI and SE).
+
+ A segment identifies a topological instruction or a service
+ instruction. A segment can either be global or local. The
+ instruction associated with a global segment is recognized and
+ executed by any SR-capable node in the domain. The instruction
+ associated with a local segment is only supported by the specific
+ node that originates it.
+
+ Let us assume some IGP (i.e.: ISIS and OSPF) extensions to define a
+ "Node Segment" as a global instruction within the IGP domain to
+ forward a packet along the shortest path to the specified node. Let
+ us further assume that within the SR domain illustrated in Figure 1,
+ segments SI, SD, SB, SE and SF respectively identify IGP node
+ segments to I, D, B, E and F.
+
+ Let us assume that node B identifies its local service S with local
+ segment SS.

+
+
+ With all of this in mind, let us describe the journey of the packet
+ P.
+
+ The packet P reaches the ingress SR edge router. I pushes the SR
+ header illustrated in Figure 2 and sets the pointer to the first
+ segment of the list (SD).
+
+ SD is an instruction recognized by all the nodes in the SR domain
+ which causes the packet to be forwarded along the shortest path to D.
+
+ Once at D, the pointer is incremented and the next segment is
+ executed (SB).
+
+ SB is an instruction recognized by all the nodes in the SR domain
+ which causes the packet to be forwarded along the shortest path to B.
+
+ Once at B, the pointer is incremented and the next segment is
+ executed (SS).
+
+ SS is an instruction only recognized by node B which causes the
+ packet to receive service S.
+
+ Once the service applied, the next segment is executed (SF) which
+ causes the packet to be forwarded along the shortest path to F.
+
+ Once at F, the pointer is incremented and the next segment is
+ executed (SE).
+
+ SE is an instruction recognized by all the nodes in the SR domain
+ which causes the packet to be forwarded along the shortest path to E.
+
+ E then removes the SR header and the packet continues its journey
+ outside the SR domain.
+
+ All of the requirements are met.
+
+ First, the packet P has not used links AB and CE: the shortest-path
+ from I to D is I-A-D, the shortest-path from D to B is D-B, the
+ shortest-path from B to F is B-C-F and the shortest-path from F to E
+ is F-E, hence the packet path through the SR domain is I-A-D-B-C-F-E
+ and the links AB and CE have been avoided.
+
+ Second, the service S supported by B has been applied on packet P.
+
+ Third, any node along the packet path is able to identify the service
+ and topological journey of the packet within the SR domain. For
+ example, node C receives the packet illustrated in Figure 3 and hence
+ is able to infer where the packet entered the SR domain (SI), how it

+
+ Figure 3: Packet P at node C
+
+ Fourth, only node I maintains per-flow state for packet P. The
+ entire program of topological and service instructions to be executed
+ by the SR domain on packet P is encoded by the ingress edge router I
+ in the SR header in the form of a list of segments where each segment
+ identifies a specific instruction. No further per-flow state is
+ required along the packet path. The per-flow state is in the SR
+ header and travels with the packet. Intermediate nodes only hold
+ states related to the IGP global node segments and the local IGP
+ adjacency segments. These segments are not per-flow specific and
+ hence scale very well. Typically, an intermediate node would
+ maintain in the order of 100's to 1000's global node segments and in
+ the order of 10's to 100 of local adjacency segments. Typically the
+ SR IGP forwarding table is expected to be much less than 10000
+ entries.
+
+ Fifth, the SR header is inserted at the entrance to the domain and
+ removed at the exit of the operator domain. For security reasons,
+ the operator can forbid anyone outside its domain to use its intra-
+ domain SR capability.
+
+4. Abstract Routing Model
+
+ At the entrance of the SR domain, the ingress SR edge router pushes
+ the SR header on top of the packet. At the exit of the SR domain,
+ the egress SR edge router removes the SR header.
+
+ The abstract SR header contains an ordered list of segments, a
+ pointer identifying the next segment to process and the
+ identifications of the ingress and egress SR edge routers on the path
+ of this packet. The pointer identifies the segment that MUST be used
+ by the receiving router to process the packet. This segment is
+ called the active segment.
+

+
+
+ A property of SR is that the entire source route of the packet,
+ including the identity of the ingress and egress edge routers is
+ always available with the packet. This allows for interesting
+ accounting and service applications.
+
+ We define three SR-header operations:
+
+ "PUSH": an SR header is pushed on an IP packet, or additional
+ segments are added at the head of the segment list. The pointer
+ is moved to the first entry of the added segments.
+
+ "NEXT": the active segment is completed, the pointer is moved to
+ the next segment in the list.
+
+ "CONTINUE": the active segment is not completed, the pointer is
+ left unchanged.
+
+ In the future, other SR-header management operations may be defined.
+
+ As the packet travels through the SR domain, the pointer is
+ incremented through the ordered list of segments and the source route
+ encoded by the SR ingress edge node is executed.
+
+ A node processes an incoming packet according to the instruction
+ associated with the active segment.
+
+ Any instruction might be associated with a segment: for example, an
+ intra-domain topological strict or loose forwarding instruction, a
+ service instruction, etc.
+
+ At minimum, a segment instruction must define two elements: the
+ identity of the next-hop to forward the packet to (this could be the
+ same node or a context within the node) and which SR-header
+ management operation to execute.
+
+ Each segment is known in the network through a Segment Identifier
+ (SID). The terms "segment" and "SID" are interchangeable.
+
+4.1. Segment Routing Global Block (SRGB)
+
+ In the SR abstract model, a segment is identified by a Segment
+ Routing Identifier (SID). The SR abstract model doesn't mandate a
+ specific format for the SID (IPv6 address or other formats).
+
+ In Segment Routing IPv6 the SID is an IPv6 address. Therefore, the
+ SRGB is materialized by the global IPv6 address space which
+ represents the set of IPv6 routable addresses in the SR domain. The
+ following rules apply:
+
+
+
+Previdi, et al. Expires June 12, 2015 [Page 8]
+
+Internet-Draft IPv6 Segment Routing Header (SRH) December 2014
+
+
+ o Each node of the SR domain MUST be configured with the Segment
+ Routing Global Block (SRGB).
+
+ o All global segments must be allocated from the SRGB. Any SR
+ capable node MUST be able to process any global segment advertised
+ by any other node within the SR domain.
+
+ o Any segment outside the SRGB has a local significance and is
+ called a "local segment". An SR-capable node MUST be able to
+ process the local segments it originates. An SR-capable node MUST
+ NOT support the instruction associated with a local segment
+ originated by a remote node.
+
+4.2. Traffic Engineering with SR
+
+ An SR Traffic Engineering policy is composed of two elements: a flow
+ classification and a segment-list to prepend on the packets of the
+ flow.
+
+ In SR, this per-flow state only exists at the ingress edge node where
+ the policy is defined and the SR header is pushed.
+
+ It is outside the scope of the document to define the process that
+ leads to the instantiation at a node N of an SR Traffic Engineering
+ policy.
+
+ [I-D.filsfils-spring-segment-routing-use-cases] illustrates various
+ alternatives:
+
+ N is deriving this policy automatically (e.g. FRR).
+
+ N is provisioned explicitly by the operator.
+
+ N is provisioned by a controller or server (e.g.: SDN Controller).
+
+ N is provisioned by the operator with a high-level policy which is
+ mapped into a path thanks to a local CSPF-based computation (e.g.
+ affinity/SRLG exclusion).
+
+ N could also be provisioned by other means.
+
+ [I-D.filsfils-spring-segment-routing-use-cases] explains why the
+ majority of use-cases require very short segment-lists, hence
+ minimizing the performance impact, if any, of inserting and
+ transporting the segment list.

+
+
+ A SDN controller, which desires to instantiate at node N an SR
+ Traffic Engineering policy, collects the SR capability of node N such
+ as to ensure that the policy meets its capability.
+
+4.3. Segment Routing Database
+
+ The Segment routing Database (SRDB) is a set of entries where each
+ entry is identified by a SID. The instruction associated with each
+ entry at least defines the identity of the next-hop to which the
+ packet should be forwarded and what operation should be performed on
+ the SR header (PUSH, CONTINUE, NEXT).
+
+ +---------+-----------+---------------------------------+
+ | Segment | Next-Hop | SR Header operation |
+ +---------+-----------+---------------------------------+
+ | Sk | M | CONTINUE |
+ | Sj | N | NEXT |
+ | Sl | NAT Srvc | NEXT |
+ | Sm | FW srvc | NEXT |
+ | Sn | Q | NEXT |
+ | etc. | etc. | etc. |

+ Each SR-capable node maintains its local SRDB. SRDB entries can
+ either derive from local policy or from protocol segment
+ advertisement.
+
+5. IPv6 Instantiation of Segment Routing
+
+5.1. Segment Identifiers (SIDs) and SRGB
+
+ Segment Routing, as described in
+ [I-D.filsfils-spring-segment-routing], defines Node-SID and
+ Adjacency-SID. When SR is used over IPv6 data-plane the following
+ applies.
+
+ The SRGB is the global IPv6 address space which represents the set of
+ IPv6 routable addresses in the SR domain.
+
+ Node SIDs are IPv6 addresses part of the SRGB (i.e.: routable
+ addresses). Adjacency-SIDs are IPv6 addresses which may not be part
+ of the global IPv6 address space.

+
+Internet-Draft IPv6 Segment Routing Header (SRH) December 2014
+
+
+5.1.1. Node-SID
+
+ The Node-SID identifies a node. With SR-IPv6 the Node-SID is an IPv6
+ prefix that the operator configured on the node and that is used as
+ the node identifier. Typically, in case of a router, this is the
+ IPv6 address of the node loopback interface. Therefore, SR-IPv6 does
+ not require any additional SID advertisement for the Node Segment.
+ The Node-SID is in fact the IPv6 address of the node.
+
+5.1.2. Adjacency-SID
+
+ In the SR architecture defined in
+ [I-D.filsfils-spring-segment-routing] the Adjacency-SID (or Adj-SID)
+ identifies a given interface and may be local or global (depending on
+ how it is advertised). A node may advertise one (or more) Adj-SIDs
+ allocated to a given interface so to force the forwarding of the
+ packet (when received with that particular Adj-SID) into the
+ interface regardless the routing entry for the packet destination.
+ The semantic of the Adj-SID is:
+
+ Send out the packet to the interface this prefix is allocated to.
+
+ When SR is applied to IPv6, any SID is in a global IPv6 address and
+ therefore, an Adj-SID has a global significance (i.e.: the IPv6
+ address representing the SID is a global address). In other words, a
+ node that advertises the Adj-SID in the form of a global IPv6 address
+ representing the link/adjacency the packet has to be forwarded to,
+ will apply to the Adj-SID a global significance.
+
+ Advertisement of Adj-SID may be done using multiple mechanisms among
+ which the ones described in ISIS and OSPF protocol extensions:
+ [I-D.ietf-isis-segment-routing-extensions] and
+ [I-D.psenak-ospf-segment-routing-ospfv3-extension]. The distinction
+ between local and global significance of the Adj-SID is given in the
+ encoding of the Adj-SID advertisement.
+
+5.2. Segment Routing Extension Header (SRH)
+
+ A new type of the Routing Header (originally defined in [RFC2460]) is
+ defined: the Segment Routing Header (SRH) which has a new Routing
+ Type, (suggested value 4) to be assigned by IANA.
+
+ As an example, if an explicit path is to be constructed across a core
+ network running ISIS or OSPF, the segment list will contain SIDs
+ representing the nodes across the path (loose or strict) which,
+ usually, are the IPv6 loopback interface address of each node. If
+ the path is across service or application entities, the segment list

+
+5.2.1. SRH and RFC2460 behavior
+
+ The SRH being a new type of the Routing Header, it also has the same
+ properties:
+
+ SHOULD only appear once in the packet.
+
+ Only the router whose address is in the DA field of the packet
+ header MUST inspect the SRH.
+
+ Therefore, Segment Routing in IPv6 networks implies that the segment
+ identifier (i.e.: the IPv6 address of the segment) is moved into the
+ DA of the packet.
+
+ The DA of the packet changes at each segment termination/completion
+ and therefore the original DA of the packet MUST be encoded as the
+ last segment of the path.
+
+ As illustrated in Section 3.2, nodes that are within the path of a
+ segment will forward packets based on the DA of the packet without
+ inspecting the SRH. This ensures full interoperability between SR-
+ capable and non-SR-capable nodes.
+
+6. SRH Procedures
+
+ In this section we describe the different procedures on the SRH.
+
+6.1. Segment Routing Operations
+
+ When Segment Routing is instantiated over the IPv6 data plane the
+ following applies:
+
+ o The segment list is encoded in the SRH.
+
+ o The active segment is in the destination address of the packet.
+
+ o The Segment Routing CONTINUE operation (as described in
+ [I-D.filsfils-spring-segment-routing]) is implemented as a
+ regular/plain IPv6 operation consisting of DA based forwarding.
+
+ o The NEXT operation is implemented through the update of the DA
+ with the value represented by the Next Segment field in the SRH.
+
+ o The PUSH operation is implemented through the insertion of the SRH
+ or the insertion of additional segments in the SRH segment list.

+
+Internet-Draft IPv6 Segment Routing Header (SRH) December 2014
+
+
+6.2. Segment Routing Node Functions
+
+ SR packets are forwarded to segments endpoints (i.e.: nodes whose
+ address is in the DA field of the packet). The segment endpoint,
+ when receiving a SR packet destined to itself, does:
+
+ o Inspect the SRH.
+
+ o Determine the next active segment.
+
+ o Update the Segments Left field (or, if requested, remove the SRH
+ from the packet).
+
+ o Update the DA.
+
+ o Send the packet to the next segment.
+
+ The procedures applied to the SRH are related to the node function.
+ Following nodes functions are defined:
+
+ Ingress SR Node.
+
+ Transit Non-SR Node.
+
+ Transit SR Intra Segment Node.
+
+ SR Endpoint Node.
+
+6.2.1. Ingress SR Node
+
+ Ingress Node can be a router at the edge of the SR domain or a SR-
+ capable host. The ingress SR node may obtain the segment list by
+ either:
+
+ Local path computation.
+
+ Local configuration.
+
+ Interaction with an SDN controller delivering the path as a
+ complete SRH.
+
+ Any other mechanism (mechanisms through which the path is acquired
+ are outside the scope of this document).
+
+ When creating the SRH (either at ingress node or in the SDN
+ controller) the following is done:
+
+ Next Header and Hdr Ext Len fields are set according to [RFC2460].
+
+
+
+Previdi, et al. Expires June 12, 2015 [Page 16]
+
+Internet-Draft IPv6 Segment Routing Header (SRH) December 2014
+
+
+ Routing Type field is set as TBD (SRH).
+
+ The Segment List is built with the FIRST segment of the path
+ encoded in the LAST element of the Segment List. Subsequent
+ segments are encoded on top of the first segment. Finally, the
+ LAST segment of the path is encoded in the FIRST element of the
+ Segment List. In other words, the Segment List is encoded in the
+ reverse order of the path.
+
+ The original DA of the packet is encoded as the last segment of
+ the path (encoded in the first element of the Segment List).
+
+ the DA of the packet is set with the value of the first segment
+ (found in the last element of the segment list).
+
+ the Segments Left field is set to n-1 where n is the number of
+ elements in the Segment List.
+
+ The packet is sent out towards the first segment (i.e.:
+ represented in the packet DA).
+
+6.2.1.1. Security at Ingress
+
+ The procedures related to the Segment Routing security are detailed
+ in [I-D.vyncke-6man-segment-routing-security].
+
+ In the case where the SR domain boundaries are not under control of
+ the network operator (e.g.: when the SR domain edge is in a home
+ network), it is important to authenticate and validate the content of
+ any SRH being received by the network operator. In such case, the
+ security procedure described in
+ [I-D.vyncke-6man-segment-routing-security] is to be used.
+
+ The ingress node (e.g.: the host in the home network) requests the
+ SRH from a control system (e.g.: an SDN controller) which delivers
+ the SRH with its HMAC signature on it.
+
+ Then, the home network host can send out SR packets (with an SRH on
+ it) that will be validated at the ingress of the network operator
+ infrastructure.
+
+ The ingress node of the network operator infrastructure, is
+ configured in order to validate the incoming SRH HMACs in order to
+ allow only packets having correct SRH according to their SA/DA
+ addresses.

+
+Internet-Draft IPv6 Segment Routing Header (SRH) December 2014
+
+
+6.2.2. Transit Non-SR Capable Node
+
+ SR is interoperable with plain IPv6 forwarding. Any non SR-capable
+ node will forward SR packets solely based on the DA. There's no SRH
+ inspection. This ensures full interoperability between SR and non-SR
+ nodes.
+
+6.2.3. SR Intra Segment Transit Node
+
+ Only the node whose address is in DA inspects and processes the SRH
+ (according to [RFC2460]). An intra segment transit node is not in
+ the DA and its forwarding is based on DA and its SR-IPv6 FIB.
+
+6.2.4. SR Segment Endpoint Node
+
+ The SR segment endpoint node is the node whose address is in the DA.
+ The segment endpoint node inspects the SRH and does:
+
+ 1. IF DA = myself (segment endpoint)
+ 2. IF Segments Left > 0 THEN
+ decrement Segments Left
+ update DA with Segment List[Segments Left]
+ 3. ELSE IF Segments List[Segments Left] <> DA THEN
+ update DA with Segments List[Segments Left]
+ IF Clean-up bit is set THEN remove the SRH
+ 4. ELSE give the packet to next PID (application)
+ End of processing.
+ 5. Forward the packet out
+
+6.3. FRR Flag Settings
+
+ A node supporting SR and doing Fast Reroute (as described in
+ [I-D.filsfils-spring-segment-routing-use-cases], when rerouting
+ packets through FRR mechanisms, SHOULD inspect the rerouted packet
+ header and look for the SRH. If the SRH is present, the rerouting
+ node SHOULD set the Protected bit on all rerouted packets.
+
+7. SR and Tunneling
+
+ Encapsulation can be realized in two different ways with SR-IPv6:
+
+ Outer encapsulation.
+
+ SRH with SA/DA original addresses.
+
+ Outer encapsulation tunneling is the traditional method where an
+ additional IPv6 header is prepended to the packet. The original IPv6
+ header being encapsulated, everything is preserved and the packet is
+
+
+
+Previdi, et al. Expires June 12, 2015 [Page 18]
+
+Internet-Draft IPv6 Segment Routing Header (SRH) December 2014
+
+
+ switched/routed according to the outer header (that could contain a
+ SRH).
+
+ SRH allows encoding both original SA and DA, hence an operator may
+ decide to change the SA/DA at ingress and restore them at egress.
+ This can be achieved without outer encapsulation, by changing SA/DA
+ and encoding the original SA in the Policy List and in the original
+ DA in the Segment List.
+
+8. Example Use Case
+
+ A more detailed description of use cases are available in
+ [I-D.ietf-spring-ipv6-use-cases]. In this section, a simple SR-IPv6
+ example is illustrated.
+
+ In the topology described in Figure 6 it is assumed an end-to-end SR
+ deployment. Therefore SR is supported by all nodes from A to J.

+ . Forward the packet to J.
+
+ . Packet travels across G and H nodes which do plain
+ IPv6 forwarding based on DA. No inspection of SRH needs
+ to be done in these nodes. However, any SR capable node
+ is allowed to set the Protected bit in case of FRR
+ protection.
+
+ . When packet arrives in J (third segment), J does:
+ . Decrement Segments Left by one: 0
+ . Update the DA with the next segment found in
+ Segment List[0]. DA is set to X.
+ . If the cleanup bit is set, then node J will strip out
+ the SRH from the packet.
+ . Forward the packet to X.

+ *
+ * o Hdr Ext Len: 8-bit unsigned integer, is the length of the SRH
+ * header in 8-octet units, not including the first 8 octets.
+ *
+ * o Routing Type: TBD, to be assigned by IANA (suggested value: 4).
+ *
+ * o Segments Left. Defined in [RFC2460], it contains the index, in
+ * the Segment List, of the next segment to inspect. Segments Left
+ * is decremented at each segment and it is used as an index in the
+ * segment list.
+ *
+ * o First Segment: offset in the SRH, not including the first 8 octets
+ * and expressed in 16-octet units, pointing to the last element of
+ * the segment list, which is in fact the first segment of the
+ * segment routing path.
+ *
+ * o Flags: 16 bits of flags. Following flags are defined:
+ *
+ * 1
+ * 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5
+ * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+ * |C|P|R|R| Policy Flags |
+ * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+ *
+ * C-flag: Clean-up flag. Set when the SRH has to be removed from
+ * the packet when packet reaches the last segment.
+ *
+ * P-flag: Protected flag. Set when the packet has been rerouted
+ * through FRR mechanism by a SR endpoint node. See Section 6.3
+ * for more details.
+ *
+ * R-flags. Reserved and for future use.
+ *
+ * Policy Flags. Define the type of the IPv6 addresses encoded
+ * into the Policy List (see below). The following have been
+ * defined:
+ *
+ * Bits 4-6: determine the type of the first element after the
+ * segment list.
+ *
+ * Bits 7-9: determine the type of the second element.
+ *
+ * Bits 10-12: determine the type of the third element.
+ *
+ * Bits 13-15: determine the type of the fourth element.
+ *
+ * The following values are used for the type:
+ *
+ * 0x0: Not present. If value is set to 0x0, it means the
+ * element represented by these bits is not present.
+ *
+ * 0x1: SR Ingress.
+ *
+ * 0x2: SR Egress.
+ *
+ * 0x3: Original Source Address.
+ *
+ * o HMAC Key ID and HMAC field, and their use are defined in
+ * [I-D.vyncke-6man-segment-routing-security].
+ *
+ * o Segment List[n]: 128 bit IPv6 addresses representing the nth
+ * segment in the Segment List. The Segment List is encoded starting
+ * from the last segment of the path. I.e., the first element of the
+ * segment list (Segment List [0]) contains the last segment of the
+ * path while the last segment of the Segment List (Segment List[n])
+ * contains the first segment of the path. The index contained in
+ * "Segments Left" identifies the current active segment.
+ *
+ * o Policy List. Optional addresses representing specific nodes in
+ * the SR path such as:
+ *
+ * SR Ingress: a 128 bit generic identifier representing the
+ * ingress in the SR domain (i.e.: it needs not to be a valid IPv6
+ * address).
+ *
+ * SR Egress: a 128 bit generic identifier representing the egress
+ * in the SR domain (i.e.: it needs not to be a valid IPv6
+ * address).
+ *
+ * Original Source Address: IPv6 address originally present in the
+ * SA field of the packet.
+ *
+ * The segments in the Policy List are encoded after the segment list
+ * and they are optional. If none are in the SRH, all bits of the
+ * Policy List Flags MUST be set to 0x0.

+# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
+# which have later been changed to m4_define as they aren't part of the
+# exported API, or moved to Autoconf or Automake where they belong.
+#
+# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
+# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)
+#
+# So we provide this file, which has a silly filename so it's always
+# included after everything else. This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
+# Yes, that means every name once taken will need to remain here until
+# we give up compatibility with versions before 1.7, at which point

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.

+\`configure' configures vpe-api-test 1.0 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]

+ --with-q-plugin-prefix vlib plugin prefix
+ --with-q-platform Build version for given platform (qnative)
+ --with-dpdk Use the Intel dpdk
+
+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ CPP C preprocessor
+ CCAS assembler compiler command (defaults to CC)
+ CCASFLAGS assembler compiler flags (defaults to CFLAGS)
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.
+
+Report bugs to the package provider.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH. The drawback is that using absolute paths prevent a
+# configured tree to be moved without reconfiguration.

+\`configure' configures vpp-japi 0.1 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
+ --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
+ --localstatedir=DIR modifiable single-machine data [PREFIX/var]

+ --with-pic[=PKGS] try to use only PIC/non-PIC objects [default=use
+ both]
+ --with-gnu-ld assume the C compiler uses GNU ld [default=no]
+ --with-sysroot=DIR Search for dependent libraries within DIR
+ (or the compiler's sysroot if not specified).
+
+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ CPP C preprocessor
+ CCAS assembler compiler command (defaults to CC)
+ CCASFLAGS assembler compiler flags (defaults to CFLAGS)
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.
+
+Report bugs to the package provider.

+# Usage: $progname [OPTION]... [MODE-ARG]...
+#
+# Provide generalized library-building support services.
+#
+# --config show all configuration variables
+# --debug enable verbose shell tracing
+# -n, --dry-run display commands without modifying any files
+# --features display basic configuration information and exit
+# --mode=MODE use operation mode MODE
+# --preserve-dup-deps don't remove duplicate dependency libraries
+# --quiet, --silent don't print informational messages
+# --no-quiet, --no-silent
+# print informational messages (default)
+# --no-warn don't display warning messages
+# --tag=TAG use configuration variables from tag TAG
+# -v, --verbose print more informational messages than default
+# --no-verbose don't print the extra informational messages
+# --version print version information
+# -h, --help, --help-all print short, long, or detailed help message
+#
+# MODE must be one of the following:
+#
+# clean remove files from the build directory
+# compile compile a source file into a libtool object
+# execute automatically set library path, then run a program
+# finish complete the installation of libtool libraries
+# install install libraries or executables
+# link create a library or an executable
+# uninstall remove libraries from an installed directory
+#
+# MODE-ARGS vary depending on the MODE. When passed as first option,
+# `--mode=MODE' may be abbreviated as `MODE' or a unique abbreviation of that.
+# Try `$progname --help --mode=MODE' for a more detailed description of MODE.

+# SYNOPSIS
+#
+# AX_CHECK_JAVA_PLUGIN(<shell-variable>)
+#
+# DESCRIPTION
+#
+# This macro sets <shell-variable> to empty on failure and to a compatible
+# version of plugin.jar otherwise. Directories searched are /usr/java/*
+# and /usr/local/java/*, which are assumed to be j{dk,re} installations.
+# Apply the shell variable as you see fit. If sun changes things so
+# <jre>/lib/plugin.jar is not the magic file it will stop working.
+#
+# This macro assumes that unzip, zipinfo or pkzipc is available (and can
+# list the contents of the jar archive). The first two are assumed to work
+# similarly enough to the infozip versisonms. The pkzipc version is
+# assumed to work if I undertstand the documentation on pkware's site but
+# YMMV. I do not have access to pwkware's version to test it.

+# SYNOPSIS

+# AX_JAVA_CHECK_CLASS(<class>,<action-if-found>,<action-if-not-found>)
+#
+# DESCRIPTION
+#
+# Test if a Java class is available. Based on AX_PROG_JAVAC_WORKS. This
+# version uses a cache variable which is both compiler, options and
+# classpath dependent (so if you switch from javac to gcj it correctly
+# notices and redoes the test).
+#
+# The macro tries to compile a minimal program importing <class>. Some
+# newer compilers moan about the failure to use this but fail or produce a
+# class file anyway. All moaing is sunk to /dev/null since I only wanted
+# to know if the class could be imported. This is a recommended followup
+# to AX_CHECK_JAVA_PLUGIN with classpath appropriately adjusted.

+# AX_CHECK_CLASS: finds if we have the given class (beware of CLASSPATH!).

+# AX_TRY_COMPILE_JAVA: attempt to compile user given source.
+#
+# AX_TRY_RUN_JAVA: attempt to compile and run user given source.
+#
+# AX_JAVA_OPTIONS: adds Java configure options.
+#
+# AX_PROG_JAVA tests an existing Java virtual machine. It uses the
+# environment variable JAVA then tests in sequence various common Java
+# virtual machines. For political reasons, it starts with the free ones.
+# You *must* call [AX_PROG_JAVAC] before.
+#
+# If you want to force a specific VM:
+#
+# - at the configure.in level, set JAVA=yourvm before calling AX_PROG_JAVA
+#
+# (but after AC_INIT)
+#
+# - at the configure level, setenv JAVA
+#
+# You can use the JAVA variable in your Makefile.in, with @JAVA@.
+#
+# *Warning*: its success or failure can depend on a proper setting of the
+# CLASSPATH env. variable.
+#
+# TODO: allow to exclude virtual machines (rationale: most Java programs
+# cannot run with some VM like kaffe).

+# SYNOPSIS
+#
+# AX_PROG_JAVA_CC
+#
+# DESCRIPTION
+#
+# Finds the appropriate java compiler on your path. By preference the java
+# compiler is gcj, then jikes then javac.
+#
+# The macro can take one argument specifying a space separated list of
+# java compiler names.
+#
+# For example:
+#
+# AX_PROG_JAVA_CC(javac, gcj)
+#
+# The macro also sets the compiler options variable: JAVA_CC_OPTS to
+# something sensible:
+#
+# - for GCJ it sets it to: @GCJ_OPTS@
+# (if GCJ_OPTS is not yet defined then it is set to "-C")
+#
+# - no other compiler has applicable options yet
+#
+# Here's an example configure.in:
+#
+# AC_INIT(Makefile.in)
+# AX_PROG_JAVA_CC()
+# AC_OUTPUT(Makefile)
+# dnl End.
+#
+# And here's the start of the Makefile.in:
+#
+# PROJECT_ROOT := @srcdir@
+# # Tool definitions.
+# JAVAC := @JAVA_CC@
+# JAVAC_OPTS := @JAVA_CC_OPTS@
+# JAR_TOOL := @jar_tool@

+# SYNOPSIS
+#
+# AX_PROG_JAVAC
+#
+# DESCRIPTION
+#
+# AX_PROG_JAVAC tests an existing Java compiler. It uses the environment
+# variable JAVAC then tests in sequence various common Java compilers. For
+# political reasons, it starts with the free ones.
+#
+# If you want to force a specific compiler:
+#
+# - at the configure.in level, set JAVAC=yourcompiler before calling
+# AX_PROG_JAVAC
+#
+# - at the configure level, setenv JAVAC
+#
+# You can use the JAVAC variable in your Makefile.in, with @JAVAC@.
+#
+# *Warning*: its success or failure can depend on a proper setting of the
+# CLASSPATH env. variable.
+#
+# TODO: allow to exclude compilers (rationale: most Java programs cannot
+# compile with some compilers like guavac).
+#
+# Note: This is part of the set of autoconf M4 macros for Java programs.
+# It is VERY IMPORTANT that you download the whole set, some macros depend
+# on other. Unfortunately, the autoconf archive does not support the
+# concept of set of macros, so I had to break it for submission. The
+# general documentation, as well as the sample configure.in, is included
+# in the AX_PROG_JAVA macro.

+# which have later been changed to m4_define as they aren't part of the
+# exported API, or moved to Autoconf or Automake where they belong.
+#
+# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
+# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)

+# So we provide this file, which has a silly filename so it's always
+# included after everything else. This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH. The drawback is that using absolute paths prevent a
+# configured tree to be moved without reconfiguration.

+\`configure' configures vpe 1.1 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
+ --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]

+ --with-gnu-ld assume the C compiler uses GNU ld [default=no]
+ --with-sysroot=DIR Search for dependent libraries within DIR
+ (or the compiler's sysroot if not specified).
+ --with-q-plugin-prefix vlib plugin prefix
+ --with-q-platform Build version for given platform (qnative)
+ --with-dpdk Use the Intel dpdk
+
+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ CPP C preprocessor
+ CCAS assembler compiler command (defaults to CC)
+ CCASFLAGS assembler compiler flags (defaults to CFLAGS)
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.
+
+Report bugs to the package provider.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH. The drawback is that using absolute paths prevent a

+\`configure' configures vppapigen 1.0 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]

+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ YACC The `Yet Another Compiler Compiler' implementation to use.
+ Defaults to the first program found out of: `bison -y', `byacc',
+ `yacc'.
+ YFLAGS The list of arguments that will be passed by default to $YACC.
+ This script will default YFLAGS to the empty string to avoid a
+ default value of `-d' given by some make applications.
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+## dummy dependencies for each header file. Too bad gcc doesn't do

+Installation Instructions
+*************************
+
+Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005 Free
+Software Foundation, Inc.
+
+This file is free documentation; the Free Software Foundation gives
+unlimited permission to copy, distribute and modify it.
+
+Basic Installation
+==================
+
+These are generic installation instructions.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+ It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring. (Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.)
+
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+ The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'. You only need
+`configure.ac' if you want to change it or regenerate `configure' using
+a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system. If you're
+ using `csh' on an old version of System V, you might need to type
+ `sh ./configure' instead to prevent `csh' from trying to execute
+ `configure' itself.
+
+ Running `configure' takes awhile. While running, it prints some
+ messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation.
+
+ 5. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+Compilers and Options
+=====================
+
+Some systems require unusual options for compilation or linking that the
+`configure' script does not know about. Run `./configure --help' for
+details on some of the pertinent environment variables.
+
+ You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment. Here
+is an example:
+
+ ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
+
+ *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+ If you have to use a `make' that does not support the `VPATH'
+variable, you have to compile the package for one architecture at a
+time in the source code directory. After you have installed the
+package for one architecture, use `make distclean' before reconfiguring
+for another architecture.
+
+Installation Names
+==================
+
+By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc. You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX'.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+There may be some features `configure' cannot figure out automatically,
+but needs to determine by the type of machine the package will run on.
+Usually, assuming the package is built to be run on the _same_
+architectures, `configure' can figure that out, but if it prints a
+message saying it cannot guess the machine type, give it the
+`--build=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+ CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+ OS KERNEL-OS
+
+ See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+ If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+ If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+If you want to set default values for `configure' scripts to share, you
+can create a site shell script called `config.site' that gives default
+values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+Variables not defined in a site shell script can be set in the
+environment passed to `configure'. However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost. In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'. For example:
+
+ ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script). Here is a another example:
+
+ /bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+Here the `CONFIG_SHELL=/bin/bash' operand causes subsequent
+configuration-related scripts to be executed by `/bin/bash'.
+
+`configure' Invocation
+======================
+
+`configure' recognizes the following options to control how it operates.
+
+`--help'
+`-h'
+ Print a summary of the options to `configure', and exit.
+
+`--version'
+`-V'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`--cache-file=FILE'
+ Enable the cache: use and save the results of the tests in FILE,
+ traditionally `config.cache'. FILE defaults to `/dev/null' to
+ disable caching.
+
+`--config-cache'
+`-C'
+ Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made. To
+ suppress all normal output, redirect it to `/dev/null' (any error
+ messages will still be shown).
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`configure' also accepts some other, not widely useful, options. Run
+`configure --help' for more details.

+Welcome to vppinfra a programming library of basic data structures.
+
+vec.c dynamic vectors
+bitmap.h dynamic bitmaps
+heap.c allocation heap of objects (sub-objects have variable size)
+pool.h allocation pool (like heap with size always 1)
+hash.c dynamic hash tables
+mheap.c memory allocator (a la dlmalloc)
+
+format.c extendable printf-like thing built on top of vectors
+std-formats.c formats for unix data structures, networking stuff, ...
+timer.c arrange for functions to be called at given times.
+
+
+Build, Test, Install, Use...
+----------------------------
+ If this package came from the distribution tar ball, skip to the
+ Build Section. If this was a gentoo ebuild, after emerge/ebuild,
+ skip to the Use Section; otherwise, start with Pre-Build.
+
+Pre-Build
+-----------
+ 1) svn checkout svn://teaktechnologies.com/fn/trunk/clib clib
+ 2) autoreconf [-v][-f][-i] # regenerate configuration files
+
+Build
+-----
+ 1) cd BUILD # which may be different than this SRC dir
+ 2) ${SRC}/configure [--host=CHOST]
+ 3) make
+
+Test
+----
+ If not cross-compiling (i.e. CBUILD == CHOST), use "make check" to
+ run the validation programs.
+
+Install
+-------
+ With the root effective user ID (i.e. su or sudo), run "make install".
+
+Use
+---
+ We need to reference man pages and theory of operation.

+# These exist entirely to fool aclocal when bootstrapping libtool.
+#
+# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
+# which have later been changed to m4_define as they aren't part of the
+# exported API, or moved to Autoconf or Automake where they belong.
+#
+# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
+# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)
+#
+# So we provide this file, which has a silly filename so it's always
+# included after everything else. This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
+# Yes, that means every name once taken will need to remain here until
+# we give up compatibility with versions before 1.7, at which point
+# we need to keep only those names which we still refer to.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an

+# One issue with vendor 'install' (even GNU) is that you can't

+# is unlikely to handle the host's binaries.
+# Fortunately install-sh will honor a STRIPPROG variable, so we
+# always use install-sh in "make install-strip", and initialize
+# STRIPPROG with the value of the STRIP variable (set by the user).

+## dummy dependencies for each header file. Too bad gcc doesn't do
+## this for us directly.
+## Some versions of gcc put a space before the ':'. On the theory

+\`configure' configures libvppinfra 1.0 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
+ --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
+ --localstatedir=DIR modifiable single-machine data [PREFIX/var]

+ --with-gnu-ld assume the C compiler uses GNU ld [default=no]
+ --with-sysroot=DIR Search for dependent libraries within DIR
+ (or the compiler's sysroot if not specified).
+ --with-cc Set CC for use as C compiler.
+ --with-cflags Set CFLAGS for use by C compiler.
+ --with-ldflags Set LDFLAGS for linking.
+ --with-unix Compile unix version of clib
+ --with-vec64 Enable 64-bit vector lengths
+
+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ CCAS assembler compiler command (defaults to CC)
+ CCASFLAGS assembler compiler flags (defaults to CFLAGS)
+ CPP C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+ * Optimize an objective function by simulated annealing
+ *
+ * Here are a couple of short, easily-understood
+ * descriptions of simulated annealing:
+ *
+ * http://www.cs.sandia.gov/opt/survey/sa.html
+ * Numerical Recipes in C, 2nd ed., 444ff
+ *
+ * The description in the Wikipedia is not helpful.
+ *
+ * The algorithm tries to produce a decent answer to combinatorially
+ * explosive optimization problems by analogy to slow cooling
+ * of hot metal, aka annealing.
+ *
+ * There are (at least) three problem-dependent annealing parameters
+ * to consider:
+ *
+ * t0, the initial "temperature. Should be set so that the probability
+ * of accepting a transition to a higher cost configuration is
+ * initially about 0.8.
+ *
+ * ntemps, the number of temperatures to use. Each successive temperature
+ * is some fraction of the previous temperature.
+ *
+ * nmoves_per_temp, the number of configurations to try at each temperature
+ *
+ * It is a black art to set ntemps, nmoves_per_temp, and the rate
+ * at which the temperature drops. Go too fast with too few iterations,
+ * and the computation falls into a local minimum instead of the
+ * (desired) global minimum.

+perfect.c: code to generate code for a hash for perfect hashing.
+(c) Bob Jenkins, September 1996, December 1999
+You may use this code in any way you wish, and it is free. No warranty.
+I hereby place this in the public domain.
+Source is http://burtleburtle.net/bob/c/perfect.c
+
+This generates a minimal perfect hash function. That means, given a
+set of n keys, this determines a hash function that maps each of
+those keys into a value in 0..n-1 with no collisions.
+
+The perfect hash function first uses a normal hash function on the key
+to determine (a,b) such that the pair (a,b) is distinct for all
+keys, then it computes a^scramble[tab[b]] to get the final perfect hash.
+tab[] is an array of 1-byte values and scramble[] is a 256-term array of
+2-byte or 4-byte values. If there are n keys, the length of tab[] is a
+power of two between n/3 and n.
+
+I found the idea of computing distinct (a,b) values in "Practical minimal
+perfect hash functions for large databases", Fox, Heath, Chen, and Daoud,
+Communications of the ACM, January 1992. They found the idea in Chichelli
+(CACM Jan 1980). Beyond that, our methods differ.
+
+The key is hashed to a pair (a,b) where a in 0..*alen*-1 and b in
+0..*blen*-1. A fast hash function determines both a and b
+simultaneously. Any decent hash function is likely to produce
+hashes so that (a,b) is distinct for all pairs. I try the hash
+using different values of *salt* until all pairs are distinct.
+
+The final hash is (a XOR scramble[tab[b]]). *scramble* is a
+predetermined mapping of 0..255 into 0..smax-1. *tab* is an
+array that we fill in in such a way as to make the hash perfect.
+
+First we fill in all values of *tab* that are used by more than one
+key. We try all possible values for each position until one works.
+
+This leaves m unmapped keys and m values that something could hash to.
+If you treat unmapped keys as lefthand nodes and unused hash values
+as righthand nodes, and draw a line connecting each key to each hash
+value it could map to, you get a bipartite graph. We attempt to
+find a perfect matching in this graph. If we succeed, we have
+determined a perfect hash for the whole set of keys.
+
+*scramble* is used because (a^tab[i]) clusters keys around *a*.

+Construct a spanning tree of *b*s with *item* as root, where each
+parent can have all its hashes changed (by some new val_b) with
+at most one collision, and each child is the b of that collision.
+
+I got this from Tarjan's "Data Structures and Network Algorithms". The
+path from *item* to a *b* that can be remapped with no collision is
+an "augmenting path". Change values of tab[b] along the path so that
+the unmapped key gets mapped and the unused hash value gets used.
+
+Assuming 1 key per b, if m out of n hash values are still unused,
+you should expect the transitive closure to cover n/m nodes before
+an unused node is found. Sum(i=1..n)(n/i) is about nlogn, so expect
+this approach to take about nlogn time to map all single-key b's.

+ * has something to do with 5/8 = 1/8 * 5. For example examine 80000,
+ * 85000, and 90000 keys with different values of a_max. This only matters
+ * if we're doing a minimal perfect hash.

+ random numbers with really excellent statistics, take a look
+ at Chapter 7...
+
+ By definition, a linear congruential random number generator
+ is of the form: rand[i+1] = a*rand[i] + c (mod m) for specific
+ values of (a,c,m).
+
+ In this case, choose m = 2**32 and use the low-order 32-bits of
+ the 64-bit product a*N[i]. Knuth suggests the use of a=1664525,
+ H.W. Lewis has tested C=1013904223 extensively. This routine is
+ reputedly as good as any 32-bit LCRN, and costs only a single
+ multiply-add.
+
+ Several variants: 32/64-bit, machine word width,
+ f64 on the closed interval [0,1].

+ * skip-list implementation
+ *
+ * Good news / bad news. As balanced binary tree schemes go,
+ * this one seems pretty fast and is reasonably simple. There's a very
+ * limited amount that can be done to mitigate sdram read latency.
+ *
+ * Each active clib_slist_elt_t is on from 1 to N lists. Each active element
+ * is always on the "level-0" list. Since most elements are *only* on
+ * level 0, we keep the level 0 (and level 1) in the element. For those
+ * elements on more than two lists, we switch to a vector. Hence, the
+ * "n" union in slib_slist_elt_t.
+ *
+ * The low-order bit of elt->n.next0[0] is 1 for inlined next indices,
+ * 0 for vector indices (since the allocator always aligns to at least
+ * a 4-byte boundary). We can only represent 2e9 items, but since the
+ * practical performance limit is O(1e7), it doesn't matter.
+ *
+ * We create a "head" element which (by construction) is always
+ * lexically lighter than any other element. This makes a large number
+ * of irritating special cases go away.
+ *
+ * User code is in charge of comparing a supplied key with
+ * the key component of a user pool element. The user tells this code
+ * to add or delete (opaque key, 32-bit integer) pairs to the skip-list.
+ *
+ * The algorithm adds new elements to one or more lists.
+ * For levels greater than zero, the probability of a new element landing on
+ * a list is branching_factor**N. Branching_factor = 0.2 seems to work
+ * OK, yielding about 50 compares per search at O(1e7) items.

+
+ The assembly code sequences for all architectures is in this one
+ file. This is because this file must be stand-alone, and we don't
+ want to have multiple files.
+
+ For VALGRIND_DO_CLIENT_REQUEST, we must ensure that the default
+ value gets put in the return slot, so that everything works when
+ this is executed not under Valgrind. Args are passed in a memory
+ block, and so there's no intrinsic limit to the number that could
+ be passed, but it's currently five.
+
+ The macro args are:
+ _zzq_rlval result lvalue
+ _zzq_default default value (result returned when running on real CPU)
+ _zzq_request request code
+ _zzq_arg1..5 request params
+
+ The other two macros are used to support function wrapping, and are
+ a lot simpler. VALGRIND_GET_NR_CONTEXT returns the value of the
+ guest's NRADDR pseudo-register and whatever other information is
+ needed to safely run the call original from the wrapper: on
+ ppc64-linux, the R2 value at the divert point is also needed. This
+ information is abstracted into a user-visible type, OrigFn.
+
+ VALGRIND_CALL_NOREDIR_* behaves the same as the following on the
+ guest, but guarantees that the branch instruction will not be
+ redirected: x86: call *%eax, amd64: call *%rax, ppc32/ppc64:
+ branch-and-link-to-r11. VALGRIND_CALL_NOREDIR is just text, not a
+ complete inline asm, since it needs to be combined with more magic
+ inline asm stuff to be useful.

+ macros. In order not to trash the stack redzone, we need to drop
+ %rsp by 128 before the hidden call, and restore afterwards. The
+ nastyness is that it is only by luck that the stack still appears
+ to be unwindable during the hidden call - since then the behaviour
+ of any routine using this macro does not match what the CFI data
+ says. Sigh.
+
+ Why is this important? Imagine that a wrapper has a stack
+ allocated local, and passes to the hidden call, a pointer to it.
+ Because gcc does not know about the hidden call, it may allocate
+ that local in the redzone. Unfortunately the hidden call may then
+ trash it before it comes to use it. So we must step clear of the
+ redzone, for the duration of the hidden call, to make it safe.
+
+ Probably the same problem afflicts the other redzone-style ABIs too
+ (ppc64-linux, ppc32-aix5, ppc64-aix5); but for those, the stack is
+ self describing (none of this CFI nonsense) so at least messing
+ with the stack pointer doesn't give a danger of non-unwindable
+ stack. */

+/* Several Valgrind tools (Memcheck, Massif, Helgrind, DRD) rely on knowing
+ when heap blocks are allocated in order to give accurate results. This
+ happens automatically for the standard allocator functions such as
+ malloc(), calloc(), realloc(), memalign(), new, new[], free(), delete,
+ delete[], etc.
+
+ But if your program uses a custom allocator, this doesn't automatically
+ happen, and Valgrind will not do as well. For example, if you allocate
+ superblocks with mmap() and then allocates chunks of the superblocks, all
+ Valgrind's observations will be at the mmap() level and it won't know that
+ the chunks should be considered separate entities. In Memcheck's case,
+ that means you probably won't get heap block overrun detection (because
+ there won't be redzones marked as unaddressable) and you definitely won't
+ get any leak detection.
+
+ The following client requests allow a custom allocator to be annotated so
+ that it can be handled accurately by Valgrind.
+
+ VALGRIND_MALLOCLIKE_BLOCK marks a region of memory as having been allocated
+ by a malloc()-like function. For Memcheck (an illustrative case), this
+ does two things:
+
+ - It records that the block has been allocated. This means any addresses
+ within the block mentioned in error messages will be
+ identified as belonging to the block. It also means that if the block
+ isn't freed it will be detected by the leak checker.
+
+ - It marks the block as being addressable and undefined (if 'is_zeroed' is
+ not set), or addressable and defined (if 'is_zeroed' is set). This
+ controls how accesses to the block by the program are handled.
+
+ 'addr' is the start of the usable block (ie. after any
+ redzone), 'sizeB' is its size. 'rzB' is the redzone size if the allocator
+ can apply redzones -- these are blocks of padding at the start and end of
+ each block. Adding redzones is recommended as it makes it much more likely
+ Valgrind will spot block overruns. `is_zeroed' indicates if the memory is
+ zeroed (or filled with another predictable value), as is the case for
+ calloc().
+
+ VALGRIND_MALLOCLIKE_BLOCK should be put immediately after the point where a
+ heap block -- that will be used by the client program -- is allocated.
+ It's best to put it at the outermost level of the allocator if possible;
+ for example, if you have a function my_alloc() which calls
+ internal_alloc(), and the client request is put inside internal_alloc(),
+ stack traces relating to the heap block will contain entries for both
+ my_alloc() and internal_alloc(), which is probably not what you want.
+
+ For Memcheck users: if you use VALGRIND_MALLOCLIKE_BLOCK to carve out
+ custom blocks from within a heap block, B, that has been allocated with
+ malloc/calloc/new/etc, then block B will be *ignored* during leak-checking
+ -- the custom blocks will take precedence.
+
+ VALGRIND_FREELIKE_BLOCK is the partner to VALGRIND_MALLOCLIKE_BLOCK. For
+ Memcheck, it does two things:
+
+ - It records that the block has been deallocated. This assumes that the
+ block was annotated as having been allocated via
+ VALGRIND_MALLOCLIKE_BLOCK. Otherwise, an error will be issued.
+
+ - It marks the block as being unaddressable.
+
+ VALGRIND_FREELIKE_BLOCK should be put immediately after the point where a
+ heap block is deallocated.
+
+ In many cases, these two client requests will not be enough to get your
+ allocator working well with Memcheck. More specifically, if your allocator
+ writes to freed blocks in any way then a VALGRIND_MAKE_MEM_UNDEFINED call
+ will be necessary to mark the memory as addressable just before the zeroing
+ occurs, otherwise you'll get a lot of invalid write errors. For example,
+ you'll need to do this if your allocator recycles freed blocks, but it
+ zeroes them before handing them back out (via VALGRIND_MALLOCLIKE_BLOCK).
+ Alternatively, if your allocator reuses freed blocks for allocator-internal
+ data structures, VALGRIND_MAKE_MEM_UNDEFINED calls will also be necessary.
+
+ Really, what's happening is a blurring of the lines between the client
+ program and the allocator... after VALGRIND_FREELIKE_BLOCK is called, the
+ memory should be considered unaddressable to the client program, but the
+ allocator knows more than the rest of the client program and so may be able
+ to safely access it. Extra client requests are necessary for Valgrind to
+ understand the distinction between the allocator and the rest of the
+ program.
+
+ Note: there is currently no VALGRIND_REALLOCLIKE_BLOCK client request; it
+ has to be emulated with MALLOCLIKE/FREELIKE and memory copying.

+/** \file
+
+ CLIB vectors are ubiquitous dynamically resized arrays with by user
+ defined "headers". Many CLIB data structures (e.g. hash, heap,
+ pool) are vectors with various different headers.
+
+ The memory layout looks like this:
+
+~~~~~~~~
+ user header (aligned to uword boundary)
+ vector length: number of elements
+ user's pointer-> vector element #0
+ vector element #1
+ ...
+~~~~~~~~
+
+ A user is returned a pointer to element # 1.
+ Null pointer vectors are valid and mean a zero length vector.
+ You can also have an allocated non-null zero length vector by just
+ setting the vector length field to zero (e.g. _vec_len (v) = 0).
+
+ Typically, the header is not present. Headers allow for other
+ data structures to be built atop CLIB vectors.
+
+ Users may specify the alignment for data elements via the
+ vec_*_aligned macros.
+
+ Vectors elements can be any C type e.g. (int, double, struct bar).
+ This is also true for data types built atop vectors (e.g. heap,
+ pool, etc.).
+
+ Many macros have _a variants supporting alignment of vector data
+ and _h variants supporting non zero length vector headers.
+ The _ha variants support both.
+
+ Standard programming error: memorize a pointer to the ith element
+ of a vector then expand it. Vectors expand by 3/2, so such code
+ may appear to work for a period of time. Memorize vector indices
+ which are invariant.

+# These exist entirely to fool aclocal when bootstrapping libtool.
+#
+# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
+# which have later been changed to m4_define as they aren't part of the
+# exported API, or moved to Autoconf or Automake where they belong.
+#
+# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
+# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)
+#
+# So we provide this file, which has a silly filename so it's always
+# included after everything else. This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
+# Yes, that means every name once taken will need to remain here until
+# we give up compatibility with versions before 1.7, at which point
+# we need to keep only those names which we still refer to.
+
+# This is to help aclocal find these macros, as it can't see m4_define.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH. The drawback is that using absolute paths prevent a

+# AM_PROG_INSTALL_STRIP
+# ---------------------
+# One issue with vendor 'install' (even GNU) is that you can't
+# specify the program used to strip binaries. This is especially
+# annoying in cross-compiling environments, where the build's strip
+# is unlikely to handle the host's binaries.
+# Fortunately install-sh will honor a STRIPPROG variable, so we
+# always use install-sh in "make install-strip", and initialize
+# STRIPPROG with the value of the STRIP variable (set by the user).
+AC_DEFUN([AM_PROG_INSTALL_STRIP],
+[AC_REQUIRE([AM_PROG_INSTALL_SH])dnl
+# Installed binaries are usually stripped using 'strip' when the user
+# run "make install-strip". However 'strip' might not be the right
+# tool to use in cross-compilation environments, therefore Automake
+# will honor the 'STRIP' environment variable to overrule this program.
+dnl Don't test for $cross_compiling = yes, because it might be 'maybe'.

+\`configure' configures sign 1.0 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
+ --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]

+ both]
+ --with-gnu-ld assume the C compiler uses GNU ld [default=no]
+ --with-sysroot=DIR Search for dependent libraries within DIR
+ (or the compiler's sysroot if not specified).
+
+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ CCAS assembler compiler command (defaults to CC)
+ CCASFLAGS assembler compiler flags (defaults to CFLAGS)
+ CPP C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.
+
+Report bugs to the package provider.
