-+.TH PPPOE-DISCOVERY 8
-+.SH NAME
-+pppoe\-discovery \- perform PPPoE discovery
-+.SH SYNOPSIS
-+.B pppoe\-discovery
-+
-+.I options
-+
-+.br
-+.BR pppoe\-discovery " { " \-V " | " \-h " }"
-+.SH DESCRIPTION
-+.LP
-+\fBpppoe\-discovery\fR performs the same discovery process as
-+\fBpppoe\fR, but does not initiate a session.
-+It sends a PADI packet and then prints the names of access
-+concentrators in each PADO packet it receives.
-+.SH OPTIONS
-+.TP
-+.BI \-I " interface"
-+.RS
-+The \fB\-I\fR option specifies the Ethernet interface to use.
-+Under Linux, it is typically eth0 or eth1.
-+The interface should be \(lqup\(rq before you start
-+\fBpppoe\-discovery\fR, but should \fInot\fR be configured to have an
-+IP address.
-+The default interface is eth0.
-+.RE
-+.TP
-+.BI \-D " file_name"
-+.RS
-+The \fB\-D\fR option causes every packet to be dumped to the specified
-+\fIfile_name\fR.
-+This is intended for debugging only.
-+.RE
-+.TP
-+.B \-U
-+.RS
-+Causes \fBpppoe\-discovery\fR to use the Host-Uniq tag in its discovery
-+packets.
-+This lets you run multiple instances of \fBpppoe\-discovery\fR and/or
-+\fBpppoe\fR without having their discovery packets interfere with one
-+another.
-+You must supply this option to \fIall\fR instances that you intend to
-+run simultaneously.
-+.RE
-+.TP
-+.BI \-S " service_name"
-+.RS
-+Specifies the desired service name.
-+\fBpppoe\-discovery\fR will only accept access concentrators which can
-+provide the specified service.
-+In most cases, you should \fInot\fR specify this option.
-+Use it only if you know that there are multiple access concentrators
-+or know that you need a specific service name.
-+.RE
-+.TP
-+.BI \-C " ac_name"
-+.RS
-+Specifies the desired access concentrator name.
-+\fBpppoe\-discovery\fR will only accept the specified access
-+concentrator.
-+In most cases, you should \fInot\fR specify this option.
-+Use it only if you know that there are multiple access concentrators.
-+If both the \fB\-S\fR and \fB\-C\fR options are specified, they must
-+\fIboth\fR match.
-+.RE
-+.TP
-+.B \-A
-+.RS
-+This option is accepted for compatibility with \fBpppoe\fR, but has no
-+effect.
-+.RE
-+.TP
-+.BR \-V " | " \-h
-+.RS
-+Either of these options causes \fBpppoe\-discovery\fR to print its
-+version number and usage information, then exit.
-+.RE
-+.SH AUTHORS
-+\fBpppoe\-discovery\fR was written by Marco d'Itri <md@linux.it>,
-+based on \fBpppoe\fR by David F. Skoll <dfs@roaringpenguin.com>.

-Subject: PATCH pppdump: Avoid out-of-range access to packet buffer
-
-This fixes a potential vulnerability where data is written to spkt.buf
-and rpkt.buf without a check on the array index.  To fix this, we
-check the array index (pkt->cnt) before storing the byte or
-incrementing the count.  This also means we no longer have a potential
-signed integer overflow on the increment of pkt->cnt.
-
-Fortunately, pppdump is not used in the normal process of setting up a
-PPP connection, is not installed setuid-root, and is not invoked
-automatically in any scenario that I am aware of.

-Subject: PATCH pppd: Negotiate IP address when only peer addresses are
- provided (#236)
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This fixes special case when both ppp ends are configured to send only IP
-address of other side and do not send its own IP address. Such setup is
-correct because both ends can exchange its IP addresses and therefore they
-have full information, they known both local and remote address.
-
-This issue can be triggered by calling pppd with arguments:
-
-    ./pppd debug local noauth nolock nodetach asyncmap 0 default-asyncmap novj noaccomp nopcomp nodeflate nobsdcomp nomagic noipv6 noipdefault nosendip :10.0.0.1 pty "./pppd debug local noauth nolock nodetach asyncmap 0 default-asyncmap novj noaccomp nopcomp nodeflate nobsdcomp nomagic noipv6 nosendip nodefaultroute :10.0.0.2 notty"
-
-Without this patch IP addresses are not exchanges at all and pppd fails:
-
-    rcvd LCP ConfReq id=0x1
-    sent LCP ConfReq id=0x1
-    sent LCP ConfAck id=0x1
-    rcvd LCP ConfAck id=0x1
-    sent LCP EchoReq id=0x0 magic=0x0
-    sent IPCP ConfReq id=0x1
-    rcvd LCP EchoReq id=0x0 magic=0x0
-    sent LCP EchoRep id=0x0 magic=0x0
-    rcvd IPCP ConfReq id=0x1
-    sent IPCP ConfAck id=0x1
-    rcvd LCP EchoRep id=0x0 magic=0x0
-    rcvd IPCP ConfAck id=0x1
-    Could not determine local IP address
-
-After applying this patch exchanging of IP addresses is working fine:
-
-    rcvd LCP ConfReq id=0x1
-    sent LCP ConfReq id=0x1
-    sent LCP ConfAck id=0x1
-    rcvd LCP ConfAck id=0x1
-    sent LCP EchoReq id=0x0 magic=0x0
-    sent IPCP ConfReq id=0x1
-    rcvd LCP EchoReq id=0x0 magic=0x0
-    sent LCP EchoRep id=0x0 magic=0x0
-    rcvd IPCP ConfReq id=0x1
-    sent IPCP ConfNak id=0x1 <addr 10.0.0.1>
-    rcvd LCP EchoRep id=0x0 magic=0x0
-    rcvd IPCP ConfNak id=0x1 <addr 10.0.0.2>
-    sent IPCP ConfReq id=0x2 <addr 10.0.0.2>
-    rcvd IPCP ConfReq id=0x2 <addr 10.0.0.1>
-    sent IPCP ConfAck id=0x2 <addr 10.0.0.1>
-    rcvd IPCP ConfAck id=0x2 <addr 10.0.0.2>
-    local  IP address 10.0.0.2
-    remote IP address 10.0.0.1

-**          computation.
-**   -- Initialize MD using MDbegin(&MD)
-**   -- For each full block (64 bytes) X you wish to process, call
-**          MD4Update(&MD,X,512)
-**      (512 is the number of bits in a full block.)
-**   -- For the last block (less than 64 bytes) you wish to process,
-**          MD4Update(&MD,X,n)
-**      where n is the number of bits in the partial block. A partial
-**      block terminates the computation, so every MD computation
-**      should terminate by processing a partial block, even if it

-.TH SRP-ENTRY 8
-.SH NAME
-srp\-entry \- Generate a SRP\-SHA1 Server Entry
-.SH SYNOPSIS
-.B srp\-entry
-
-.I \-i index
- 
-.I clientname
-
-.SH DESCRIPTION
-.LP
-This utility generates an entry suitable for use in the
-/etc/ppp/srp\-secrets file on a PPP EAP SRP\-SHA1 authenticator
-("server").  This file has the same basic layout as the other pppd(8)
-authentication files, /etc/ppp/pap\-secrets and /etc/ppp/chap\-secrets.
-Thus, the entry generated has at least four main fields separated by
-spaces.  The first field is the authenticatee ("client") name.  The
-second is the server name.  The third is the secret.  The fourth is
-the allowed (or assigned) IP address for the client, and defaults to
-"*".  Additional fields can contain additional IP addresses or pppd
-options; see pppd(8) for details.
-.LP
-The third field has three subfields, separated by colons.  The first
-subfield is the index of the modulus and generator from SRP's
-/etc/tpasswd.conf.  The special value 0 is used to represent the
-well-known modulus and generator specified in the EAP SRP\-SHA1 draft.
-The second subfield is the password validator.  The third is the
-password salt.  These latter two values are encoded in base64 notation.
-.SH OPTIONS
-.TP
-.I \-i <index>
-Specifies the modulus/generator index in /etc/tpasswd.conf.  In order
-to use this option, you will need to run the "tconf" utility from the
-SRP package to generate local entries for this file.  Note that if
-these values are not known to the client, the client will be forced to
-run time-consuming safety tests on the values used.  For this reason,
-using the well-known values is recommended.
-.TP
-.I <clientname>
-Specifies the client name.  The password validator is a hashed
-combination of the client's name and password, and both are required.
-If the client name is not supplied on the command line, srp\-entry will
-prompt for the client name first.
-.SH FILES
-.TP
-.B /etc/ppp/srp\-secrets
-Usernames, passwords and IP addresses for SRP authentication.  This
-file should be owned by root and not readable or writable by any other
-user.  Pppd will log a warning if this is not the case.  Note that
-srp\-entry does not write to this file.  The user is responsible for
-copying the output of srp\-entry into this file.
-.TP
-.B /etc/tpasswd.conf
-Indexed copies of tested modulus/generator combinations; part of the
-SRP package.

+Installation Instructions
+*************************
+
+   Copyright (C) 1994-1996, 1999-2002, 2004-2017, 2020-2021 Free
+Software Foundation, Inc.
+
+   Copying and distribution of this file, with or without modification,
+are permitted in any medium without royalty provided the copyright
+notice and this notice are preserved.  This file is offered as-is,
+without warranty of any kind.
+
+Basic Installation
+==================
+
+   Briefly, the shell command './configure && make && make install'
+should configure, build, and install this package.  The following
+more-detailed instructions are generic; see the 'README' file for
+instructions specific to this package.  Some packages provide this
+'INSTALL' file but do not implement all of the features documented
+below.  The lack of an optional feature in a given package is not
+necessarily a bug.  More recommendations for GNU packages can be found
+in *note Makefile Conventions: (standards)Makefile Conventions.
+
+   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 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.
+
+     Running 'configure' might take a while.  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, generally using the just-built uninstalled binaries.
+
+  4. Type 'make install' to install the programs and any data files and
+     documentation.  When installing into a prefix owned by root, it is
+     recommended that the package be configured and built as a regular
+     user, and only the 'make install' phase executed with root
+     privileges.
+
+  5. Optionally, type 'make installcheck' to repeat any self-tests, but
+     this time using the binaries in their final installed location.
+     This target does not install anything.  Running this target as a
+     regular user, particularly if the prior 'make install' required
+     root privileges, verifies that the installation completed
+     correctly.
+
+  6. 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.
+
+  7. Often, you can also type 'make uninstall' to remove the installed
+     files again.  In practice, not all packages have tested that
+     uninstallation works correctly, even though it is required by the
+     GNU Coding Standards.
+
+  8. Some packages, particularly those that use Automake, provide 'make
+     distcheck', which can by used by developers to test that all other
+     targets like 'make install' and 'make uninstall' work correctly.
+     This target is generally not run by end users.
+
+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=c99 CFLAGS=-g 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 can use 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 '..'.  This is known
+as a "VPATH" build.
+
+   With a non-GNU 'make', it is safer 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.
+
+   On MacOS X 10.5 and later systems, you can create libraries and
+executables that work on multiple system types--known as "fat" or
+"universal" binaries--by specifying multiple '-arch' options to the
+compiler but only a single '-arch' option to the preprocessor.  Like
+this:
+
+     ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+                 CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+                 CPP="gcc -E" CXXCPP="g++ -E"
+
+   This is not guaranteed to produce working output in all cases, you
+may have to build one architecture at a time and combine the results
+using the 'lipo' tool if you have problems.
+
+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', where PREFIX must be an
+absolute file name.
+
+   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.  In general, the default
+for these options is expressed in terms of '${prefix}', so that
+specifying just '--prefix' will affect all of the other directory
+specifications that were not explicitly provided.
+
+   The most portable way to affect installation locations is to pass the
+correct locations to 'configure'; however, many packages provide one or
+both of the following shortcuts of passing variable assignments to the
+'make install' command line to change installation locations without
+having to reconfigure or recompile.
+
+   The first method involves providing an override variable for each
+affected directory.  For example, 'make install
+prefix=/alternate/directory' will choose an alternate location for all
+directory configuration variables that were expressed in terms of
+'${prefix}'.  Any directories that were specified during 'configure',
+but not in terms of '${prefix}', must each be overridden at install time
+for the entire installation to be relocated.  The approach of makefile
+variable overrides for each directory variable is required by the GNU
+Coding Standards, and ideally causes no recompilation.  However, some
+platforms have known limitations with the semantics of shared libraries
+that end up requiring recompilation when using this method, particularly
+noticeable in packages that use GNU Libtool.
+
+   The second method involves providing the 'DESTDIR' variable.  For
+example, 'make install DESTDIR=/alternate/directory' will prepend
+'/alternate/directory' before all installation names.  The approach of
+'DESTDIR' overrides is not required by the GNU Coding Standards, and
+does not work on platforms that have drive letters.  On the other hand,
+it does better at avoiding recompilation issues, and works well even
+when some directory options were not specified in terms of '${prefix}'
+at 'configure' time.
+
+Optional Features
+=================
+
+   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'.
+
+   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.
+
+   Some packages offer the ability to configure how verbose the
+execution of 'make' will be.  For these packages, running './configure
+--enable-silent-rules' sets the default to minimal output, which can be
+overridden with 'make V=1'; while running './configure
+--disable-silent-rules' sets the default to verbose, which can be
+overridden with 'make V=0'.
+
+Particular systems
+==================
+
+   On HP-UX, the default C compiler is not ANSI C compatible.  If GNU CC
+is not installed, it is recommended to use the following options in
+order to use an ANSI C compiler:
+
+     ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
+
+and if that doesn't work, install pre-built binaries of GCC for HP-UX.
+
+   HP-UX 'make' updates targets which have the same timestamps as their
+prerequisites, which makes it generally unusable when shipped generated
+files such as 'configure' are involved.  Use GNU 'make' instead.
+
+   On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
+parse its '<wchar.h>' header file.  The option '-nodtk' can be used as a
+workaround.  If GNU CC is not installed, it is therefore recommended to
+try
+
+     ./configure CC="cc"
+
+and if that doesn't work, try
+
+     ./configure CC="cc -nodtk"
+
+   On Solaris, don't put '/usr/ucb' early in your 'PATH'.  This
+directory contains several dysfunctional programs; working variants of
+these programs are available in '/usr/bin'.  So, if you need '/usr/ucb'
+in your 'PATH', put it _after_ '/usr/bin'.
+
+   On Haiku, software installed for all users goes in '/boot/common',
+not '/usr/local'.  It is recommended to use the following options:
+
+     ./configure --prefix=/boot/common
+
+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).
+
+Unfortunately, this technique does not work for 'CONFIG_SHELL' due to an
+Autoconf limitation.  Until the limitation is lifted, you can use this
+workaround:
+
+     CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+'configure' Invocation
+======================
+
+   'configure' recognizes the following options to control how it
+operates.
+
+'--help'
+'-h'
+     Print a summary of all of the options to 'configure', and exit.
+
+'--help=short'
+'--help=recursive'
+     Print a summary of the options unique to this package's
+     'configure', and exit.  The 'short' variant lists options used only
+     in the top level, while the 'recursive' variant lists options also
+     present in any nested packages.
+
+'--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.
+
+'--prefix=DIR'
+     Use DIR as the installation prefix.  *note Installation Names:: for
+     more details, including other options available for fine-tuning the
+     installation locations.
+
+'--no-create'
+'-n'
+     Run the configure checks, but stop before creating any output
+     files.
+
+'configure' also accepts some other, not widely useful, options.  Run
+'configure --help' for more details.

+What's new since ppp-2.4.9 (unreleased)
+***************************************
+
+* New pppd options:
+  - ipv6-up-script
+  - ipv6-down-script
+
+What's new in ppp-2.4.9.
+************************
+
+* Support for new EAP (Extensible Authentication Protocol) methods:
+  - Support for EAP-TLS, from Jan Just Keijser and others
+  - Support for EAP-MSCHAPv2, from Eivind Næss, Thomas Omerzu, Tijs
+    Van Buggenhout and others
+
+* New pppd options:
+  - chap-timeout
+  - chapms-strip-domain
+  - replacedefaultroute
+  - noreplacedefaultroute
+  - ipv6cp-accept-remote
+  - lcp-echo-adaptive
+  - ip-up-script
+  - ip-down-script
+  - ca
+  - capath
+  - cert
+  - key
+  - crl-dir
+  - crl
+  - max-tls-version
+  - need-peer-eap
+
+* Fixes for CVE-2020-8597 and CVE-2015-3310.
+
+* libpcap is now required when compiling on Linux (previously, if
+  libpcap was not present, pppd would be compiled without packet
+  filtering support).
+
+* The rp-pppoe plugin has been renamed to pppoe, to distinguish it
+  from the upstream rp-pppoe code.  Its options have changed names,
+  but the old names are kept as aliases.
+
+* The configure script now supports cross-compilation.
+
+* Many bug fixes and cleanups.
+  
+
+What was new in ppp-2.4.8.
+**************************
+
+* New pppd options have been added:
+  - ifname, to set the name for the PPP interface device
+  - defaultroute-metric, to set the metric for the default route
+  - defaultroute6, to add an IPv6 default route (with nodefaultroute6
+    to prevent adding an IPv6 default route)
+  - up_sdnotify, to have pppd notify systemd when the link is up.
+
+* The rp-pppoe plugin has new options:
+  - host-uniq, to set the Host-Uniq value to send
+  - pppoe-padi-timeout, to set the timeout for discovery packets
+  - pppoe-padi-attempts, to set the number of discovery attempts.
+
+* Added the CLASS attribute in radius packets.
+
+* Sundry bug fixes.
+
+* Fixed warnings and issues found by static analysis.
+
+* Added Submitting-patches.md.
+
+
+What was new in ppp-2.4.7.
+**************************
+
+* Fixed a potential security issue in parsing option files (CVE-2014-3158).
+
+* There is a new "stop-bits" option, which takes an argument of 1 or 2,
+  indicating the number of stop bits to use for async serial ports.
+
+* Various bug fixes.
+
+
+What was new in ppp-2.4.6.
+**************************
+
+* Man page updates.
+
+* Several bug fixes.
+
+* Options files can now set and unset environment variables for
+  scripts.
+
+* The timeout for chat scripts can now be taken from an environment
+  variable.
+
+* There is a new option, master_detach, which allows pppd to detach
+  from the controlling terminal when it is the multilink bundle master
+  but its own link has terminated, even if the nodetach option has
+  been given.
+
+
+What was new in ppp-2.4.5.
+**************************
+
+* Under Linux, pppd can now operate in a mode where it doesn't request
+  the peer's IP address, as some peers refuse to supply an IP address.
+  Since Linux supports device routes as well as gateway routes, it's
+  possible to have no remote IP address assigned to the ppp interface
+  and still route traffic over it.
+
+* Pppd now works better with 3G modems that do strange things such as
+  sending IPCP Configure-Naks with the same values over and over again.
+
+* The PPP over L2TP plugin is included, which works with the pppol2tp
+  PPP channel code in the Linux kernel.  This allows pppd to be used
+  to set up tunnels using the Layer 2 Tunneling Protocol.
+
+* A new 'enable-session' option has been added, which enables session
+  accounting via PAM or wtwp/wtmpx, as appropriate.  See the pppd man
+  page for details.
+
+* Several bugs have been fixed.
+
+
+What was new in ppp-2.4.4.
+**************************
+
+* Pppd will now run /etc/ppp/ip-pre-up, if it exists, after creating
+  the ppp interface and configuring its IP addresses but before
+  bringing it up.  This can be used, for example, for adding firewall
+  rules for the interface.
+
+* Lots of bugs fixed, particularly in the area of demand-dialled and
+  persistent connections.
+
+* The rp-pppoe plugin now accepts any interface name (that isn't an
+  existing pppd option name) without putting "nic-" on the front of
+  it, not just eth*, nas*, tap* and br*.
+
+
+What was new in ppp-2.4.3.
+**************************
+
+* The configure script now accepts --prefix and --sysconfdir options.
+  These default to /usr/local and /etc.  If you want pppd put in
+  /usr/sbin as before, use ./configure --prefix=/usr.
+
+* Doing `make install' no longer puts example configuration files in
+  /etc/ppp.  Use `make install-etcppp' if you want that.
+
+* The code has been updated to work with version 0.8.3 of libpcap.
+  Unfortunately the libpcap maintainers removed support for the
+  "inbound" and "outbound" keywords on PPP links, meaning that if you
+  link pppd with libpcap-0.8.3, you can't use those keywords in the
+  active-filter and pass-filter expressions.  The support has been
+  reinstated in the CVS version and should be in future libpcap
+  releases.  If you need the in/outbound keywords, use a later release
+  than 0.8.3, or get the CVS version from http://www.tcpdump.org.
+
+* There is a new option, child-timeout, which sets the length of time
+  that pppd will wait for child processes (such as the command
+  specified with the pty option) to exit before exiting itself.  It
+  defaults to 5 seconds.  After the timeout, pppd will send a SIGTERM
+  to any remaining child processes and exit.  A value of 0 means no
+  timeout.
+
+* Various bugs have been fixed, including some CBCP packet parsing
+  bugs that could lead to the peer being able to crash pppd if CBCP
+  support is enabled.
+
+* Various fixes and enhancements to the radius and rp-pppoe plugins
+  have been added.
+
+* There is a new winbind plugin, from Andrew Bartlet of the Samba
+  team, which provides the ability to authenticate the peer against an
+  NT domain controller using MS-CHAP or MS-CHAPV2.
+
+* There is a new pppoatm plugin, by various authors, sent in by David
+  Woodhouse.
+
+* The multilink code has been substantially reworked.  The first pppd
+  for a bundle still controls the ppp interface, but it doesn't exit
+  until all the links in the bundle have terminated.  If the first
+  pppd is signalled to exit, it signals all the other pppds
+  controlling links in the bundle.
+
+* The TDB code has been updated to the latest version.  This should
+  eliminate the problem that some people have seen where the database
+  file (/var/run/pppd.tdb) keeps on growing.  Unfortunately, however,
+  the new code uses an incompatible database format.  For this reason,
+  pppd now uses /var/run/pppd2.tdb as the database filename.
+
+
+What was new in ppp-2.4.2.
+**************************
+
+* The CHAP code has been rewritten.  Pppd now has support for MS-CHAP
+  V1 and V2 authentication, both as server and client.  The new CHAP
+  code is cleaner than the old code and avoids some copyright problems
+  that existed in the old code.
+
+* MPPE (Microsoft Point-to-Point Encryption) support has been added,
+  although the current implementation shouldn't be considered
+  completely secure.  (There is no assurance that the current code
+  won't ever transmit an unencrypted packet.)
+
+* James Carlson's implementation of the Extensible Authentication
+  Protocol (EAP) has been added.
+
+* Support for the Encryption Control Protocol (ECP) has been added.
+

+  - A plug-in for supplying the PAP password over a pipe from another
+    process
+  - A plug-in for authenticating using a Radius server.
+
+* Updates and bug-fixes for the Solaris port.
+
+* The CBCP (Call Back Control Protocol) code has been updated.  There
+  are new options `remotenumber' and `allow-number'.
+
+* Extra hooks for plugins to use have been added.
+
+* There is now a `maxoctets' option, which causes pppd to terminate
+  the link once the number of bytes passed on the link exceeds a given
+  value.
+
+* There are now options to control whether pppd can use the IPCP
+  IP-Address and IP-Addresses options: `ipcp-no-address' and
+  `ipcp-no-addresses'.
+
+* Fixed several bugs, including potential buffer overflows in chat.
+
+
+What was new in ppp-2.4.1.
+**************************
+
+* Pppd can now print out the set of options that are in effect.  The
+  new `dump' option causes pppd to print out the option values after
+  option parsing is complete.  The `dryrun' option causes pppd to
+  print the options and then exit.
+
+* The option parsing code has been fixed so that options in the
+  per-tty options file are parsed correctly, and don't override values
+  from the command line in most cases.
+
+* The plugin option now looks in /usr/lib/pppd/<pppd-version> (for
+  example, /usr/lib/pppd/2.4.1b1) for shared objects for plugins if
+  there is no slash in the plugin name.
+
+* When loading a plugin, pppd will now check the version of pppd for
+  which the plugin was compiled, and refuse to load it if it is
+  different to pppd's version string.  To enable this, the plugin
+  source needs to #include "pppd.h" and have a line saying:

+Sometimes it is necessary for a plugin to access details related to

+allows a plugin to inspect e.g. key details after authentication has been
+completed, but before the key material is cleared from memory for security
+reasons.
+
+There are in particularly 3 functions that allow one to inspect these
+keys:
+
+* bool mppe_keys_isset()
+* int mppe_get_recv_key(unsigned char *key, int length)
+* int mppe_get_send_key(unsigned char *key, int length)
+
+The first function indicates whether or not the key material is set and
+is valid. The two latter functions will allow one to obtain a copy
+of the respective receive and send keys. The return value of these
+functions is the length of the valid key material. For security reasons,
+one should take care to clear these copies when work is complete. The
+max length of MPPE receive ands send keys are up to 32 bytes long, or
+of MPPE_MAX_KEY_SIZE length.
+
+The previous definitions of MPPE_MAX_KEY_LEN is the maximum length in
+which the Linux kernel will accept for MPPE key lengths. Plugins would
+access the MPPE keys directly via the:
 
+  extern u_char mppe_send_keyMPPE_MAX_KEY_LEN
+  extern u_char mppe_recv_keyMPPE_MAX_KEY_LEN
 
+variables. The 2.5.0 release prohibits the direct access of these
+variables by making them static and private in favor of using the new
+API.

-  - Support for EAP-MSCHAPv2, from Eivind Næss, Thomas Omerzu, Tijs
-    Van Buggenhout and others
-
+The 2.5.0 release is a major release of pppd which contains breaking 
+changes for third-party plugins, a complete revamp of the build-system
+and that allows for flexibility of configuring features as needed.
+
+In Summary:
+* Support for PEAP authentication by Eivind Næss and Rustam Kovhaev
+* Support for loading PKCS12 certificate envelopes 
+* Adoption of GNU Autoconf / Automake build environment, by Eivind Næss
+  and others.
+* Support for pkgconfig tool has been added by Eivind Næss.

+  - Defines in which describes what features was included in pppd
+  - Functions now prefixed with explicit ppp_* to indicate that
+    pppd functions being called.
+  - Header files were renamed to better align with their features,
+    and now use proper include guards
+  - A pppdconf.h file is supplied to allow third-party modules to use
+    the same feature defines pppd was compiled with.
+  - No extern declarations of internal variable names of pppd, 
+    continued use of these extern variables are considered 
+    unstable.
+* Lots of internal fixes and cleanups for Radius and PPPoE by Jaco Kroon
+* Dropped IPX support, as Linux has dropped support in version 5.15
+  for this protocol.
+* Many more fixes and cleanups.
+* Pppd is no longer installed setuid-root.

-
-* libpcap is now required when compiling on Linux (previously, if
-  libpcap was not present, pppd would be compiled without packet
-  filtering support).
-
-* The rp-pppoe plugin has been renamed to pppoe, to distinguish it
-  from the upstream rp-pppoe code.  Its options have changed names,
-  but the old names are kept as aliases.
-
-* The configure script now supports cross-compilation.
-
-* Many bug fixes and cleanups.

-
-What was new in ppp-2.4.8.
-**************************
-
-* New pppd options have been added:
-  - ifname, to set the name for the PPP interface device
-  - defaultroute-metric, to set the metric for the default route
-  - defaultroute6, to add an IPv6 default route (with nodefaultroute6
-    to prevent adding an IPv6 default route)
-  - up_sdnotify, to have pppd notify systemd when the link is up.
-
-* The rp-pppoe plugin has new options:
-  - host-uniq, to set the Host-Uniq value to send
-  - pppoe-padi-timeout, to set the timeout for discovery packets
-  - pppoe-padi-attempts, to set the number of discovery attempts.

-
-* There is a new option, master_detach, which allows pppd to detach
-  from the controlling terminal when it is the multilink bundle master
-  but its own link has terminated, even if the nodetach option has
-  been given.
-
-
-What was new in ppp-2.4.5.
-**************************
-
-* Under Linux, pppd can now operate in a mode where it doesn't request
-  the peer's IP address, as some peers refuse to supply an IP address.
-  Since Linux supports device routes as well as gateway routes, it's
-  possible to have no remote IP address assigned to the ppp interface
-  and still route traffic over it.
-
-* Pppd now works better with 3G modems that do strange things such as
-  sending IPCP Configure-Naks with the same values over and over again.
-
-* The PPP over L2TP plugin is included, which works with the pppol2tp
-  PPP channel code in the Linux kernel.  This allows pppd to be used
-  to set up tunnels using the Layer 2 Tunneling Protocol.
-
-* A new 'enable-session' option has been added, which enables session
-  accounting via PAM or wtwp/wtmpx, as appropriate.  See the pppd man
-  page for details.
-
-* Several bugs have been fixed.
-
-
-What was new in ppp-2.4.4.
-**************************
-
-* Pppd will now run /etc/ppp/ip-pre-up, if it exists, after creating
-  the ppp interface and configuring its IP addresses but before
-  bringing it up.  This can be used, for example, for adding firewall
-  rules for the interface.
-
-* Lots of bugs fixed, particularly in the area of demand-dialled and
-  persistent connections.
-
-* The rp-pppoe plugin now accepts any interface name (that isn't an
-  existing pppd option name) without putting "nic-" on the front of
-  it, not just eth*, nas*, tap* and br*.
-

-
-* Doing `make install' no longer puts example configuration files in
-  /etc/ppp.  Use `make install-etcppp' if you want that.
-
-* The code has been updated to work with version 0.8.3 of libpcap.

+# 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

+# Configuration subroutine to validate and canonicalize a configuration type.
+# Supply the specified configuration type as an argument.
+# If it is invalid, we print an error message on stderr and exit with code 1.
+# Otherwise, we print the canonical config type on stdout and succeed.

+
+# This file is supposed to be the same for all GNU packages
+# and recognize all the CPU types, system types and aliases
+# that are meaningful with *any* GNU software.
+# Each package is responsible for reporting which valid configurations
+# it does not support.  The user should be able to distinguish
+# a failure to support a valid configuration from a meaningless
+# configuration.
+
+# The goal of this file is to map all the various variations of a given
+# machine specification into a single specification in the form:
+#	CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
+# or in some cases, the newer four-part form:
+#	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
+# It is wrong to echo any other type of specification.
+
+# The "shellcheck disable" line above the timestamp inhibits complaints
+# about features and limitations of the classic Bourne shell that were
+# superseded or lifted in POSIX.  However, this script identifies a wide
+# variety of pre-POSIX systems that do not have POSIX shells at all, and
+# even some reasonably current systems (Solaris 10 as case-in-point) still
+# have a pre-POSIX /bin/sh.

+\`configure' configures ppp 2.5.0 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 \`..'

+                          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'.

+##   -MM, not -M (despite what the docs say).  Also, it might not be
+##   supported by the other compilers which use the 'gcc' depmode.
+## - Using -M directly means running the compiler twice (even worse

+## This next piece of magic avoids the "deleted header file" problem.
+## The problem is that when a header file which appears in a .P file
+## is deleted, the dependency causes make to die (because there is
+## typically no way to rebuild the header).  We avoid this by adding
+## 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
+## that the space means something, we add a space to the output as
+## well.  hp depmode also adds that space, but also prefixes the VPATH
+## to the object.  Take care to not repeat it in the output.
+## Some versions of the HPUX 10.20 sed can't process this invocation

+#         of 'echo a\ b'.  This is slower than default on some shells.

+#         wrapping double-quotes.

+## ------ ##
+## Usage. ##
+## ------ ##
+
+# This file is a library for parsing options in your shell scripts along
+# with assorted other useful supporting features that you can make use
+# of too.
+#
+# For the simplest scripts you might need only:
+#
+#   #!/bin/sh
+#   . relative/path/to/funclib.sh
+#   . relative/path/to/options-parser
+#   scriptversion=1.0
+#   func_options ${1+"$@"}
+#   eval set dummy "$func_options_result"; shift
+#   ...rest of your script...
+#
+# In order for the '--version' option to work, you will need to have a
+# suitably formatted comment like the one at the top of this file
+# starting with '# Written by ' and ending with '# Copyright'.
+#
+# For '-h' and '--help' to work, you will also need a one line
+# description of your script's purpose in a comment directly above the
+# '# Written by ' line, like the one at the top of this file.
+#
+# The default options also support '--debug', which will turn on shell
+# execution tracing (see the comment above debug_cmd below for another
+# use), and '--verbose' and the func_verbose function to allow your script
+# to display verbose messages only when your user has specified
+# '--verbose'.
+#
+# After sourcing this file, you can plug in processing for additional
+# options by amending the variables from the 'Configuration' section
+# below, and following the instructions in the 'Option parsing'
+# section further down.
+
+## -------------- ##
+## Configuration. ##
+## -------------- ##
+
+# You should override these variables in your script after sourcing this
+# file so that they reflect the customisations you have added to the
+# option parser.
+
+# The usage line for option parsing errors and the start of '-h' and
+# '--help' output messages. You can embed shell variables for delayed
+# expansion at the time the message is displayed, but you will need to

+# expanded when the contents are evaled.

+# 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.

+.SH NAME
+pppoe\-discovery \- perform PPPoE discovery
+.SH SYNOPSIS
+.B pppoe\-discovery
+
+.I options
+
+.br
+.BR pppoe\-discovery " { " \-V " | " \-h " }"
+.SH DESCRIPTION
+.LP
+\fBpppoe\-discovery\fR performs the same discovery process as
+\fBpppoe\fR, but does not initiate a session.
+It sends a PADI packet and then prints the names of access
+concentrators in each PADO packet it receives.
+.SH OPTIONS
+.TP
+.BI \-I " interface"
+.RS
+The \fB\-I\fR option specifies the Ethernet interface to use.
+Under Linux, it is typically eth0 or eth1.
+The interface should be \(lqup\(rq before you start
+\fBpppoe\-discovery\fR, but should \fInot\fR be configured to have an
+IP address.
+This option is mandatory.
+.RE
+.TP
+.BI \-D " file_name"
+.RS
+The \fB\-D\fR option causes every packet to be dumped to the specified
+\fIfile_name\fR.
+This is intended for debugging only.
+.RE
+.TP
+.B \-U
+.RS
+Causes \fBpppoe\-discovery\fR to use the Host-Uniq tag in its discovery
+packets.
+This lets you run multiple instances of \fBpppoe\-discovery\fR and/or
+\fBpppoe\fR without having their discovery packets interfere with one
+another.
+You must supply this option to \fIall\fR instances that you intend to
+run simultaneously.
+.RE
+.TP
+.BI \-S " service_name"
+.RS
+Specifies the desired service name.
+\fBpppoe\-discovery\fR will only accept access concentrators which can
+provide the specified service.

-/*
- *  ALGORITHM
- *
- *      The "deflation" process depends on being able to identify portions
- *      of the input text which are identical to earlier input (within a
- *      sliding window trailing behind the input currently being processed).
- *
- *      The most straightforward technique turns out to be the fastest for
- *      most input files: try all possible matches and select the longest.
- *      The key feature of this algorithm is that insertions into the string
- *      dictionary are very simple and thus fast, and deletions are avoided
- *      completely. Insertions are performed at each input character, whereas
- *      string matches are performed only when the previous match ends. So it
- *      is preferable to spend more time in matches to allow very fast string
- *      insertions and avoid deletions. The matching algorithm for small
- *      strings is inspired from that of Rabin & Karp. A brute force approach
- *      is used to find longer strings when a small match has been found.
- *      A similar algorithm is used in comic (by Jan-Mark Wams) and freeze
- *      (by Leonid Broukhis).
- *         A previous version of this file used a more sophisticated algorithm
- *      (by Fiala and Greene) which is guaranteed to run in linear amortized
- *      time, but has a larger average cost, uses more memory and is patented.
- *      However the F&G algorithm may be faster for some highly redundant
- *      files if the parameter max_chain_length (described below) is too large.
- *
- *  ACKNOWLEDGEMENTS
- *
- *      The idea of lazy evaluation of matches is due to Jan-Mark Wams, and
- *      I found it in 'freeze' written by Leonid Broukhis.
- *      Thanks to many people for bug reports and testing.

- *
- *      The "deflation" process uses several Huffman trees. The more
- *      common source values are represented by shorter bit sequences.
- *
- *      Each code tree is stored in a compressed form which is itself
- * a Huffman encoding of the lengths of all the code strings (in
- * ascending order by source values).  The actual code strings are
- * reconstructed from the lengths in the inflate process, as described

-  Performs one or both of the following actions:
-
-  - Compress more input starting at next_in and update next_in and avail_in
-    accordingly. If not all input can be processed (because there is not
-    enough room in the output buffer), next_in and avail_in are updated and
-    processing will resume at this point for the next call of deflate().
-
-  - Provide more output starting at next_out and update next_out and avail_out
-    accordingly. This action is forced if the parameter flush is non zero.
-    Forcing flush frequently degrades the compression ratio, so this parameter
-    should be set only when necessary (in interactive applications).
-    Some output may be provided even if flush is not set.
-
-  Before the call of deflate(), the application should ensure that at least
-  one of the actions is possible, by providing more input and/or consuming
-  more output, and updating avail_in or avail_out accordingly; avail_out
-  should never be zero before the call. The application can consume the
-  compressed output when it wants, for example when the output buffer is full
-  (avail_out == 0), or after each call of deflate().
-
-    If the parameter flush is set to Z_PARTIAL_FLUSH, the current compression
-  block is terminated and flushed to the output buffer so that the
-  decompressor can get all input data available so far. For method 9, a future
-  variant on method 8, the current block will be flushed but not terminated.
-  If flush is set to Z_FULL_FLUSH, the compression block is terminated, a
-  special marker is output and the compression dictionary is discarded; this
-  is useful to allow the decompressor to synchronize if one compressed block
-  has been damaged (see inflateSync below).  Flushing degrades compression and
-  so should be used only when necessary.  Using Z_FULL_FLUSH too often can
-  seriously degrade the compression. If deflate returns with avail_out == 0,
-  this function must be called again with the same value of the flush
-  parameter and more output space (updated avail_out), until the flush is
-  complete (deflate returns with non-zero avail_out).
-
-    If the parameter flush is set to Z_PACKET_FLUSH, the compression
-  block is terminated, and a zero-length stored block is output,
-  omitting the length bytes (the effect of this is that the 3-bit type
-  code 000 for a stored block is output, and the output is then
-  byte-aligned).  This is designed for use at the end of a PPP packet.
-  In addition, if the current compression block contains all the data
-  since the last Z_PACKET_FLUSH, it is never output as a stored block.
-  If the current compression block output as a static or dynamic block
-  would not be at least `minCompression' bytes smaller than the
-  original data, then nothing is output for that block.  (The type
-  code for the zero-length stored block is still output, resulting in
-  a single zero byte being output for the whole packet.)
-  `MinCompression' is a parameter to deflateInit2, or 0 if deflateInit
-  is used.
-
-    If the parameter flush is set to Z_FINISH, all pending input is processed,
-  all pending output is flushed and deflate returns with Z_STREAM_END if there
-  was enough output space; if deflate returns with Z_OK, this function must be
-  called again with Z_FINISH and more output space (updated avail_out) but no
-  more input data, until it returns with Z_STREAM_END or an error. After
-  deflate has returned Z_STREAM_END, the only possible operations on the
-  stream are deflateReset or deflateEnd.
-  
-    Z_FINISH can be used immediately after deflateInit if all the compression
-  is to be done in a single step. In this case, avail_out must be at least
-  0.1% larger than avail_in plus 12 bytes.  If deflate does not return
-  Z_STREAM_END, then it must be called again as described above.
-
-    deflate() may update data_type if it can make a good guess about
-  the input data type (Z_ASCII or Z_BINARY). In doubt, the data is considered
-  binary. This field is only for information purposes and does not affect
-  the compression algorithm in any manner.
-
-    deflate() returns Z_OK if some progress has been made (more input
-  processed or more output produced), Z_STREAM_END if all input has been
-  consumed and all output has been produced (only when flush is set to
-  Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example
-  if next_in or next_out was NULL), Z_BUF_ERROR if no progress is possible.

-
-     The method parameter is the compression method. It must be 8 in this
-   version of the library. (Method 9 will allow a 64K history buffer and
-   partial block flushes.)
-
-     The windowBits parameter is the base two logarithm of the window size
-   (the size of the history buffer).  It should be in the range 8..15 for this
-   version of the library (the value 16 will be allowed for method 9). Larger
-   values of this parameter result in better compression at the expense of
-   memory usage. The default value is 15 if deflateInit is used instead.
-
-    The memLevel parameter specifies how much memory should be allocated
-   for the internal compression state. memLevel=1 uses minimum memory but
-   is slow and reduces compression ratio; memLevel=9 uses maximum memory
-   for optimal speed. The default value is 8. See zconf.h for total memory
-   usage as a function of windowBits and memLevel.
-
-     The strategy parameter is used to tune the compression algorithm. Use
-   the value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data
-   produced by a filter (or predictor), or Z_HUFFMAN_ONLY to force Huffman
-   encoding only (no string match).  Filtered data consists mostly of small
-   values with a somewhat random distribution. In this case, the
-   compression algorithm is tuned to compress them better. The strategy
-   parameter only affects the compression ratio but not the correctness of
-   the compressed output even if it is not set appropriately.
-
-     The minCompression parameter specifies the minimum reduction in size
-   required for a compressed block to be output when Z_PACKET_FLUSH is
-   used (see the description of deflate above).
-
-     If next_in is not null, the library will use this buffer to hold also
-   some history information; the buffer must either hold the entire input
-   data, or have at least 1<<(windowBits+1) bytes and be writable. If next_in
-   is null, the library will allocate its own history buffer (and leave next_in
-   null). next_out need not be provided here but must be provided by the
-   application for the next call of deflate().
-
-     If the history buffer is provided by the application, next_in must
-   must never be changed by the application since the compressor maintains
-   information inside this buffer from call to call; the application
-   must provide more input only by increasing avail_in. next_in is always
-   reset by the library in this case.
-
-      deflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was
-   not enough memory, Z_STREAM_ERROR if a parameter is invalid (such as
-   an invalid method). msg is set to null if there is no error message.
-   deflateInit2 does not perform any compression: this will be done by
-   deflate().

-

-   compression state which can be quite large, so this strategy is slow and
