-# SYNOPSIS
-#
-#   AC_PROG_SWIG([major.minor.micro])
-#
-# DESCRIPTION
-#
-#   This macro searches for a SWIG installation on your system. If found you
-#   should call SWIG via $(SWIG). You can use the optional first argument to
-#   check if the version of the available SWIG is greater than or equal to
-#   the value of the argument. It should have the format: N[.N[.N]] (N is a
-#   number between 0 and 999. Only the first N is mandatory.)
-#
-#   If the version argument is given (e.g. 1.3.17), AC_PROG_SWIG checks that
-#   the swig package is this version number or higher.
-#
-#   In configure.in, use as:
-#
-#     AC_PROG_SWIG(1.3.17)
-#     SWIG_ENABLE_CXX
-#     SWIG_MULTI_MODULE_SUPPORT
-#     SWIG_PYTHON

+# SYNOPSIS
+#
+#   ACX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
+#
+# DESCRIPTION
+#
+#   This macro figures out how to build C programs using POSIX threads.
+#   It sets the PTHREAD_LIBS output variable to the threads library and
+#   linker flags, and the PTHREAD_CFLAGS output variable to any special
+#   C compiler flags that are needed. (The user can also force certain
+#   compiler flags/libs to be tested by setting these environment
+#   variables.)
+#
+#   Also sets PTHREAD_CC to any special C compiler that is needed for
+#   multi-threaded programs (defaults to the value of CC otherwise).
+#   (This is necessary on AIX to use the special cc_r compiler alias.)
+#
+#   NOTE: You are assumed to not only compile your program with these
+#   flags, but also link it with them as well. e.g. you should link
+#   with $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS
+#   $LIBS
+#
+#   If you are only building threads programs, you may wish to use
+#   these variables in your default LIBS, CFLAGS, and CC:
+#
+#          LIBS="$PTHREAD_LIBS $LIBS"
+#          CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
+#          CC="$PTHREAD_CC"
+#
+#   In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute
+#   constant has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to
+#   that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
+#
+#   ACTION-IF-FOUND is a list of shell commands to run if a threads
+#   library is found, and ACTION-IF-NOT-FOUND is a list of commands to
+#   run it if it is not found. If ACTION-IF-FOUND is not specified, the
+#   default action will define HAVE_PTHREAD.
+#
+#   Please let the authors know if this macro fails on any platform, or
+#   if you have any other suggestions or comments. This macro was based
+#   on work by SGJ on autoconf scripts for FFTW (http://www.fftw.org/)
+#   (with help from M. Frigo), as well as ac_pthread and hb_pthread
+#   macros posted by Alejandro Forero Cuervo to the autoconf macro
+#   repository. We are also grateful for the helpful feedback of
+#   numerous users.

-# SYNOPSIS
-#
-#   AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
-#
-# DESCRIPTION
-#
-#   This macro figures out how to build C programs using POSIX threads. It
-#   sets the PTHREAD_LIBS output variable to the threads library and linker
-#   flags, and the PTHREAD_CFLAGS output variable to any special C compiler
-#   flags that are needed. (The user can also force certain compiler
-#   flags/libs to be tested by setting these environment variables.)
-#
-#   Also sets PTHREAD_CC to any special C compiler that is needed for
-#   multi-threaded programs (defaults to the value of CC otherwise). (This
-#   is necessary on AIX to use the special cc_r compiler alias.)
-#
-#   NOTE: You are assumed to not only compile your program with these flags,
-#   but also link it with them as well. e.g. you should link with
-#   $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
-#
-#   If you are only building threads programs, you may wish to use these
-#   variables in your default LIBS, CFLAGS, and CC:
-#
-#     LIBS="$PTHREAD_LIBS $LIBS"
-#     CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
-#     CC="$PTHREAD_CC"
-#
-#   In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
-#   has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name
-#   (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
-#
-#   Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
-#   PTHREAD_PRIO_INHERIT symbol is defined when compiling with
-#   PTHREAD_CFLAGS.
-#
-#   ACTION-IF-FOUND is a list of shell commands to run if a threads library
-#   is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
-#   is not found. If ACTION-IF-FOUND is not specified, the default action
-#   will define HAVE_PTHREAD.
-#
-#   Please let the authors know if this macro fails on any platform, or if
-#   you have any other suggestions or comments. This macro was based on work
-#   by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
-#   from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
-#   Alejandro Forero Cuervo to the autoconf macro repository. We are also
-#   grateful for the helpful feedback of numerous users.

 Known issues
 ------------

-  Only happens for (sub)zones that are blocked by default; e.g. 10.in-addr.arpa
 o If libevent is older (before 1.3c), unbound will exit instead of reload
   on sighup. On a restart 'did not exit gracefully last time' warning is 
   printed. Perform ./configure --with-libevent=no or update libevent, rerun 
   configure and recompile unbound to make sighup work correctly.

doc/README.DNS64

@@ -1,30 +0,0 @@
-The DNS64 code was written by Viagenie, 2009, by Simon Perrault as part
-of the Ecdysis project.  The code is copyright by them, and has the BSD
-license (see the dns64/dns64.c file).
-
-To enable DNS64 functionality in Unbound, two directives in unbound.conf must
-be edited:
-
-1. The "module-config" directive must start with "dns64". For example:
-
-    module-config: "dns64 validator iterator"
-
-If you're not using DNSSEC then you may remove "validator".
-
-2. The "dns64-prefix" directive indicates your DNS64 prefix. For example:
-
-    dns64-prefix: 64:FF9B::/96
-
-The prefix must be a /96 or shorter.
-
-To test that things are working right, perform a query against Unbound for a
-domain name for which no AAAA record exists. You should see a AAAA record in
-the answer section. The corresponding IPv6 address will be inside the DNS64
-prefix. For example:
-
-    $ unbound -c unbound.conf
-    $ dig @localhost jazz-v4.viagenie.ca aaaa
-    [...]
-    ;; ANSWER SECTION:
-    jazz-v4.viagenie.ca.        86400   IN      AAAA    64:ff9b::ce7b:1f02

-o NXDOMAIN and SOA serial numbers.
-  Unbound keeps TTL values for message formats, and thus rcodes, such
-  as NXDOMAIN.  Also it keeps the latest rrsets in the rrset cache.
-  So it will faithfully negative cache for the exact TTL as originally
-  specified for an NXDOMAIN message, but send a newer SOA record if
-  this has been found in the mean time.  In point, this could lead to a
-  negative cached NXDOMAIN reply with a SOA RR where the serial number
-  indicates a zone version where this domain is not any longer NXDOMAIN.
-  These situations become consistent once the original TTL expires.
-  If the domain is DNSSEC signed, by the way, then NSEC records are
-  updated more carefully.  If one of the NSEC records in an NXDOMAIN is
-  updated from another query, the NXDOMAIN is dropped from the cache,
-  and queried for again, so that its proof can be checked again.
-
-o SOA records in negative cached answers for DS queries.
-  The current unbound code uses a negative cache for queries for type DS.
-  This speeds up building chains of trust, and uses NSEC and NSEC3
-  (optout) information to speed up lookups.  When used internally,
-  the bare NSEC(3) information is sufficient, probably picked up from
-  a referral.  When answering to clients, a SOA record is needed for
-  the correct message format, a SOA record is picked from the cache
-  (and may not actually match the serial number of the SOA for which the
-  NSEC and NSEC3 records were obtained) if available otherwise network
-  queries are performed to get the data.
-
-o Parent and child with different nameserver information.
-  A misconfiguration that sometimes happens is where the parent and child
-  have different NS, glue information.  The child is authoritative, and
-  unbound will not trust information from the parent nameservers as the
-  final answer.  To help lookups, unbound will however use the parent-side
-  version of the glue as a last resort lookup.  This resolves lookups for
-  those misconfigured domains where the servers reported by the parent
-  are the only ones working, and servers reported by the child do not.
-
-o Failure of validation and probing.
-  Retries on a validation failure are now 5x to a different nameserver IP
-  (if possible), and then it gives up, for one name, type, class entry in
-  the message cache.  If a DNSKEY or DS fails in the chain of trust in the
-  key cache additionally, after the probing, a bad key entry is created that
-  makes the entire zone bogus for 900 seconds.  This is a fixed value at
-  this time and is conservative in sending probes.  It makes the compound
-  effect of many resolvers less and easier to handle, but penalizes
-  individual resolvers by having less probes and a longer time before fixes
-  are picked up.

-This tool provides builtin default contents for the root anchor and root
-update certificate files.
-.P
-It tests if the root anchor file works, and if not, and an update is possible,
-attempts to update the root anchor using the root update certificate.
-It performs a https fetch of root-anchors.xml and checks the results, if
-all checks are successful, it updates the root anchor file.  Otherwise
-the root anchor file is unchanged.  It performs RFC5011 tracking if the
-DNSSEC information available via the DNS makes that possible.
-.P
-It does not perform an update if the certificate is expired, if the network
-is down or other errors occur.
-.P
-The available options are:
-.TP
-.B \-a \fIfile
-The root anchor key file, that is read in and written out.
-Default is @UNBOUND_ROOTKEY_FILE@.
-If the file does not exist, or is empty, a builtin root key is written to it.
-.TP
-.B \-c \fIfile
-The root update certificate file, that is read in.
-Default is @UNBOUND_ROOTCERT_FILE@.
-If the file does not exist, or is empty, a builtin certificate is used.
-.TP
-.B \-l
-List the builtin root key and builtin root update certificate on stdout.
-.TP
-.B \-u \fIname
-The server name, it connects to https://name.  Specify without https:// prefix.
-The default is "data.iana.org".  It connects to the port specified with \-P.
-You can pass an IPv4 addres or IPv6 address (no brackets) if you want.
-.TP
-.B \-x \fIpath
-The pathname to the root\-anchors.xml file on the server. (forms URL with \-u).
-The default is /root\-anchors/root\-anchors.xml.
-.TP
-.B \-s \fIpath
-The pathname to the root\-anchors.p7s file on the server. (forms URL with \-u).
-The default is /root\-anchors/root\-anchors.p7s.  This file has to be a PKCS7
-signature over the xml file, using the pem file (\-c) as trust anchor.
-.TP
-.B \-n \fIname
-The emailAddress for the Subject of the signer's certificate from the p7s
-signature file.  Only signatures from this name are allowed.  default is
-dnssec@iana.org.  If you pass "" then the emailAddress is not checked.
-.TP
-.B \-4
-Use IPv4 for domain resolution and contacting the server on https.  Default is
-to use IPv4 and IPv6 where appropriate.
-.TP
-.B \-6
-Use IPv6 for domain resolution and contacting the server on https.  Default is
-to use IPv4 and IPv6 where appropriate.
-.TP
-.B \-f \fIresolv.conf
-Use the given resolv.conf file.  Not enabled by default, but you could try to
-pass /etc/resolv.conf on some systems.  It contains the IP addresses of the
-recursive nameservers to use.  However, since this tool could be used to
-bootstrap that very recursive nameserver, it would not be useful (since
-that server is not up yet, since we are bootstrapping it).  It could be
-useful in a situation where you know an upstream cache is deployed (and
-running) and in captive portal situations.
-.TP
-.B \-r \fIroot.hints
-Use the given root.hints file (same syntax as the BIND and Unbound root hints
-file) to bootstrap domain resolution.  By default a list of builtin root
-hints is used.  Unbound\-anchor goes to the network itself for these roots,
-to resolve the server (\-u option) and to check the root DNSKEY records.
-It does so, because the tool when used for bootstrapping the recursive
-resolver, cannot use that recursive resolver itself because it is bootstrapping
-that server.
-.TP
-.B \-v
-More verbose. Once prints informational messages, multiple times may enable
-large debug amounts (such as full certificates or byte\-dumps of downloaded
-files).  By default it prints almost nothing.  It also prints nothing on
-errors by default; in that case the original root anchor file is simply
-left undisturbed, so that a recursive server can start right after it.
-.TP
-.B \-C \fIunbound.conf
-Debug option to read unbound.conf into the resolver process used.
-.TP
-.B \-P \fIport
-Set the port number to use for the https connection.  The default is 443.
-.TP
-.B \-F
-Debug option to force update of the root anchor through downloading the xml
-file and verifying it with the certificate.  By default it first tries to
-update by contacting the DNS, which uses much less bandwidth, is much
-faster (200 msec not 2 sec), and is nicer to the deployed infrastructure.
-With this option, it still attempts to do so (and may verbosely tell you),
-but then ignores the result and goes on to use the xml fallback method.
-.TP
-.B \-h
-Show the version and commandline option help.
-.SH "EXIT CODE"
-This tool exits with value 1 if the root anchor was updated using the
-certificate or if the builtin root-anchor was used.  It exits with code
-0 if no update was necessary, if the update was possible with RFC5011
-tracking, or if an error occurred.
-.P
-You can check the exit value in this manner:
-.nf
