If found, # then SWIG is AC_SUBST'd; if not found, then $SWIG is empty. If SWIG is # found, then SWIG_LIB is set to the SWIG library path, and AC_SUBST'd. # # 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), AX_PKG_SWIG checks that the swig package is this version number # or higher. # # As usual, action-if-found is executed if SWIG is found, otherwise # action-if-not-found is executed. # # In configure.in, use as: # # AX_PKG_SWIG(1.3.17, [], [ AC_MSG_ERROR([SWIG is required to build..]) ]) # AX_SWIG_ENABLE_CXX # AX_SWIG_MULTI_MODULE_SUPPORT # AX_SWIG_PYTHON # # LICENSE # # Copyright (c) 2008 Sebastian Huber # Copyright (c) 2008 Alan W.

where:

NAME            an owner name, i.e., the name of the node to which this
                resource record pertains.

TYPE            two octets containing one of the RR TYPE codes.

CLASS           two octets containing one of the RR CLASS codes.

TTL             a 32 bit signed integer that specifies the time interval
                that the resource record may be cached before the source
                of the information should again be consulted.  Zero
                values are interpreted to mean that the RR can only be
                used for the transaction in progress, and should not be

where:

ID              A 16 bit identifier assigned by the program that
                generates any kind of query.  This identifier is copied
                the corresponding reply and can be used by the requester
                to match up replies to outstanding queries.

QR              A one bit field that specifies whether this message is a
                query (0), or a response (1).

OPCODE          A four bit field that specifies kind of query in this
                message.  This value is set by the originator of a query
                and copied into the response.  The values are:

                0               a standard query (QUERY)

                1               an inverse query (IQUERY)

                2               a server status request (STATUS)

                3-15            reserved for future use

AA              Authoritative Answer - this bit is valid in responses,
                and specifies that the responding name server is an
                authority for the domain name in question section.

                Note that the contents of the answer section may have
                multiple owner names because of aliases.  The AA bit

                corresponds to the name which matches the query name, or
                the first owner name in the answer section.

TC              TrunCation - specifies that this message was truncated
                due to length greater than that permitted on the
                transmission channel.

RD              Recursion Desired - this bit may be set in a query and
                is copied into the response.  If RD is set, it directs
                the name server to pursue the query recursively.
                Recursive query support is optional.

RA              Recursion Available - this be is set or cleared in a
                response, and denotes whether recursive query support is
                available in the name server.

Z               Reserved for future use.  Must be zero in all queries
                and responses.

RCODE           Response code - this 4 bit field is set as part of
                responses.  The values have the following
                interpretation:

                0               No error condition

                1               Format error - The name server was
                                unable to interpret the query.

                2               Server failure - The name server was
                                unable to process this query due to a
                                problem with the name server.

                3               Name Error - Meaningful only for
                                responses from an authoritative name
                                server, this code signifies that the
                                domain name referenced in the query does
                                not exist.

                4               Not Implemented - The name server does
                                not support the requested kind of query.

                5               Refused - The name server refuses to
                                perform the specified operation for
                                policy reasons.  For example, a name
                                server may not wish to provide the
                                information to the particular requester,
                                or a name server may not wish to perform
                                a particular operation (e.g., zone

                                transfer) for particular data.

                6-15            Reserved for future use.

QDCOUNT         an unsigned 16 bit integer specifying the number of
                entries in the question section.

ANCOUNT         an unsigned 16 bit integer specifying the number of
                resource records in the answer section.

NSCOUNT         an unsigned 16 bit integer specifying the number of name
                server resource records in the authority records
                section.

ARCOUNT         an unsigned 16 bit integer specifying the number of

A secondary benefit of using ldns is speed, because ldns is written in C, and although it is not optimized for performance, it should be a lot faster than Perl. The first main tool to use ldns is Drill, from which part of the library was derived. From version 1.0.0 on, drill is included in the ldns release and will not be distributed separately anymore. The library also includes some other examples and tools to show how it can be used. These can be found in the examples/ directory in the tarball. ldns depends on OpenSSL for it's cryptographic functions. Feature list - Transparent IPv4 and IPv6 support (overridable if necessary), - TSIG support, - DNSSEC support; signing and verification, - small size, - online documentation as well as manual pages. If you want to send us patches please use the code from git. \section using_ldns Using ldns Almost all interaction between an application and ldns goes through the ldns data structures (\ref ldns_rr, \ref ldns_pkt, etc.). These are input or output to the functions of ldns. For example, \ref ldns_zone_new_frm_fp reads a zone from a \c FILE pointer, and returns an \ref ldns_zone structure. Let's use Drill as an example. Drill is a tool much like dig, whose most basic function is to send 1 query to a nameserver and print the response. To be able to do this, drill uses the resolver module of ldns, which acts as a stub resolver. The resolver module uses the net module to actually send the query that drill requested. It then uses the wire2host module to translate the response and place it in ldns' internal structures. These are passed back to drill, which then uses the host2str module to print the response in presentation format. \section gettingstarted Getting Started See the \ref design page for a very high level description of the design choices made for ldns. For an overview of the functions and types ldns provides, you can check out the \ref ldns ldns header file descriptions. If you want to see some libdns action, you can read our tutorials: - \ref tutorial1_mx - \ref tutorial2_zone - \ref tutorial3_signzone Or you can just use the menu above to browse through the API docs.

Don't override it # in your configure.ac. # # This macro checks for Python and tries to get the include path to # 'Python.h'. It provides the $(PYTHON_CPPFLAGS) and $(PYTHON_LIBS) output # variables. It also exports $(PYTHON_EXTRA_LIBS) and # $(PYTHON_EXTRA_LDFLAGS) for embedding Python in your code. # # You can search for some particular version of Python by passing a # parameter to this macro, for example ">= '2.3.1'", or "== '2.4'". Please # note that you *have* to pass also an operator along with the version to # match, and pay special attention to the single quotes surrounding the # version number. Don't use "PYTHON_VERSION" for this: that environment # variable is declared as precious and thus reserved for the end-user. # # This macro should work for all versions of Python >= 2.1.0. As an end # user, you can disable the check for the python version by setting the # PYTHON_NOVERSIONCHECK environment variable to something else than the # empty string. # # If you need to use this macro for an older Python version, please # contact the authors. We're always open for feedback. # # LICENSE # # Copyright (c) 2009 Sebastian Huber # Copyright (c) 2009 Alan W.

It fires the warning # (with _au_warn_XXX), outputs it into the updated configure.ac (with # m4_warn), and then outputs the replacement expansion. We need extra # quotation around the m4_warn and dnl so they will be written # unexpanded into the updated configure.ac. # This is an auxiliary macro that is also run when # autoupdate runs m4. It simply calls m4_warning, but # we need a wrapper so that each warning is emitted only # once. We break the quoting in m4_warning's argument in # order to expand this macro's arguments, not AU_DEFUN's. # Finally, this is the expansion that is picked up by # autoconf, causing NAME to expand to NEW-CODE, plus # (if SILENT is not "silent") a m4_warning telling the # maintainer to run autoupdate.

If found, # then SWIG is AC_SUBST'd; if not found, then $SWIG is empty. If SWIG is # found, then SWIG_LIB is set to the SWIG library path, and AC_SUBST'd. # # 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), AX_PKG_SWIG checks that the swig package is this version number # or higher. # # As usual, action-if-found is executed if SWIG is found, otherwise # action-if-not-found is executed. # # In configure.in, use as: # # AX_PKG_SWIG(1.3.17, [], [ AC_MSG_ERROR([SWIG is required to build..]) ]) # AX_SWIG_ENABLE_CXX # AX_SWIG_MULTI_MODULE_SUPPORT # AX_SWIG_PYTHON # # LICENSE # # Copyright (c) 2008 Sebastian Huber # Copyright (c) 2008 Alan W.

(thanks David Keeler) * bugfix #403: Fix heap overflow (thanks David Keeler) * bugfix #404: Make parsing APL strings more robust (thanks David Keeler) * bugfix #391: Complete library assessment to prevent assertion errors through ldns_rdf_size usage. * Slightly more specific error messaging on wrong number of rdata fields with the LDNS_STATUS_MISSING_RDATA_FIELDS_RRSIG and LDNS_STATUS_MISSING_RDATA_FIELDS_KEY result codes. * bugfix #406: More rigorous openssl result code handling to prevent future crashes within openssl. * Fix ldns_fetch_valid_domain_keys to search deeper than just one level for a DNSKEY that signed a DS RR. (this function was used in the check_dnssec_trace nagios module) * bugfix #407: Canonicalize TSIG dnames and algorithm fields * A new output specifier to accommodate configuration of what to show in comment texts when converting host and/or wire-format data to string. All conversion to string and printing functions have a new version that have such a format specifier as an extra argument. The default is changed so that only DNSKEY RR's are annotated with an comment show the Key Tag of the DNSKEY. * Fixed the ldns resolver to not mark a nameserver unreachable when edns0 is tried unsuccessfully with size 4096 (no return packet came), but to still try TCP. A big UDP packet might have been corrupted by fragments dropping firewalls. * Update of libdns.vim (thanks Miek Gieben) * Added the ldnsx Python module to our contrib section, which adds even more pythonisticism to the usage of ldns with Python. (Many thanks to Christopher Olah and Paul Wouters) The ldnsx module is automatically installed when --with-pyldns is used with configuring, but may explicitly be excluded with the --without-pyldnsx option to configure. * bugfix #410: Fix clearing out temporary data on stack in sha2.c * bugfix #411: Don't let empty non-terminal NSEC3s cause assertion failure. 1.6.10 2011-05-31 * New example tool

in the python wrappers to enable the python garbage collector by Bedrich Kosata. * bugfix #380: Minimizing effect of discrepancies in sizeof(bool) at build time and when used. * bugfix #383: Fix detection of empty nonterminals of multiple labels. * Fixed the omission of rrsets in nsec(3)s and rrsigs to all occluded names (in stead of just the ones that contain glue only) and all occluded records on the delegation points (in stead of just the glue). * Clarify the operation of ldns_dnssec_mark_glue and the usage of ldns_dnssec_node_next_nonglue functions in the documentation. * Added function ldns_dnssec_mark_and_get_glue as an real fast alternative for ldns_zone_glue_rr_list. * Fix parse buffer overflow for max length domain names. * Fix Makefile for U in environment, since wrong

wrapper for ldns_fetch_valid_domain_keys by Bedrich Kosata. * fix to compile python wrapper with swig 2.0.2. * Don't fallback to SHA-1 when creating NSEC3 hash with another algorithm identifier, fail instead (no other algorithm identifiers are assigned yet). 1.6.8 2011-01-24 * Fix ldns zone, so that $TTL definition match RFC 2308. * Fix lots of missing checks on allocation failures and parse of NSEC with many types and max parse length in hosts_frm_fp routine and off by one in read_anchor_file routine (thanks Dan Kaminsky and Justin Ferguson). * bugfix #335: Drill: Print both SHA-1 and SHA-256 corresponding DS records. * Print correct WHEN in query packet (is not always 1-1-1970) * ldns-test-edns: new example tool that detects EDNS support. * fix ldns_resolver_send without openssl. * bugfix #342: patch for support for more CERT key types (RFC4398). * bugfix #351: fix udp_send hang if UDP checksum error. * fix set_bit (from NSEC3 sign) patch from Jan Komissar. 1.6.7 2010-11-08 *

RRs on subsequent messages (section 4.4, RFC 2845, thanks to Michael Sheldon). * bugfix: signer sigs nsecs with zsks only. * bugfix #333: fix ldns_dname_absolute for name ending with backslash. 1.6.6 2010-08-09 * Fix ldns_rr_clone to copy question rrs properly. * Fix ldns_sign_zone(_nsec3) to clone the soa for the new zone. * Fix ldns_wire2dname size check from reading 1 byte beyond buffer end. *

exclude SOA record from comparison. * --disable-rpath fix * fix ldns_pkt_empty(), reported by Alex Nicoll. * fix ldns_resolver_new_frm_fp not ignore lines after a comment. * python code for ldns_rr.new_question_frm_str() * Fix ldns_dnssec_verify_denial: the signature selection routine. * Type TALINK parsed (draft-ietf-dnsop-trust-history). * bugfix #304: fixed dead loop in ldns_tcp_read_wire() and ldns_tcp_read_wire_timeout(). * GOST support with correct algorithm numbers. The plan is to make it enabled if openssl support is detected, but it is disabled by default in this release because the RFC is not ready. * Fixed comment in rbtree.h about being first member and data ptr. * Fixed possibly leak in case of out of memory in ldns_native2rdf... * ldns_dname_is_wildcard added. * Fixed: signatures over wildcards had the wrong labelcount. * Fixed ldns_verify() inconsistent return values. * Fixed ldns_resolver to copy and free tsig name, data and algorithm. * Fixed ldns_resolver to push search onto searchlist. * A ldns resolver now defaults to a non-recursive resolver that handles the TC bit. * ldns_resolver_print() prints more details. * Fixed ldns_rdf2buffer_str_time(), which did not print timestamps on 64bit systems. * Make ldns_resolver_nameservers_randomize() more random. * bugfix #310: POSIX specifies NULL second argument of gettimeofday. * fix compiler warnings from llvm clang compiler. * bugfix #309: ldns_pkt_clone did not clone the tsig_rr. * Fix gentoo ebuild for drill, 'no m4 directory'. * bugfix #313: drill trace on an empty nonterminal continuation. 1.6.4 2010-01-20 * Imported pyldns contribution by Zdenek Vasicek and Karel Slany. Changed its configure and Makefile to fit into ldns. Added its dname_* methods to the rdf_* class (as is the ldns API). Changed swig destroy of ldns_buffer class to ldns_buffer_free. Declared ldns_pkt_all and ldns_pkt_all_noquestion so swig sees them. * Bugfix: parse PTR target of .tomhendrikx.nl with error not crash. * Bugfix: handle escaped characters in TXT rdata. * bug292: no longer crash on malformed domain names where a label is on position 255, which was a buffer overflow by one. * Fix ldns_get_rr_list_hosts_frm_fp_l (strncpy to strlcpy change), which fixes resolv.conf reading badly terminated string buffers. * Fix ldns_pkt_set_random_id to be more random, and a little faster, it did not do value 0 statistically correctly. * Fix ldns_rdf2native_sockaddr_storage to set sockaddr type to zeroes, for portability. * bug295: nsec3-hash routine no longer case sensitive. * bug298: drill failed nsec3 denial of existence proof. 1.6.3 2009-12-04 * Bugfix: allow for unknown resource records in zonefile with rdlen=0. * Bugfix: also mark an RR as question if it comes from the wire * Bugfix: NSEC3 bitmap contained NSEC * Bugfix: Inherit class when creating signatures 1.6.2 2009-11-12 * Fix Makefile patch from Havard Eidnes, better install.sh usage. * Fix parse error on SOA serial of 2910532839. Fix print of ';' and readback of '\;' in names, also for '\\'. Fix parse of '\(' and '\)' in names. Also for file read. Also '\.' * Fix signature creation when TTLs are different for RRs in RRset. * bug273: fix so EDNS rdata is included in pkt to wire conversion. * bug274: fix use of c++ keyword 'class' for RR class in the code. * bug275: fix memory leak of packet edns rdata. * Fix timeout procedure for TCP and AXFR on Solaris. * Fix occasional NSEC bitmap bogus * Fix rr comparing (was in reversed order since 1.6.0) * bug278: fix parsing HINFO rdata (and other cases). * Fix previous owner name: also pick up if owner name is @. * RFC5702: enabled sha2 functions by default. This requires OpenSSL 0.9.8 or higher. Reason for this default is the root to be signed with RSASHA256. * Fix various LDNS RR parsing issues: IPSECKEY, WKS, NSAP, very long lines * Fix: Make ldns_dname_is_subdomain case insensitive. * Fix ldns-verify-zone so that address records at zone NS set are not considered glue (Or glue records fall below delegation) * Fix LOC RR altitude printing. * Feature: Added period (e.g. '3m6d') support at explicit TTLs. * Feature: DNSKEY rrset by default signed with minimal signatures but -A option for ldns-signzone to sign it with all keys. This makes the DNSKEY responses smaller for signed domains. 1.6.1 2009-09-14 * --enable-gost : use the GOST algorithm (experimental). * Added some missing options to drill manpage * Some fixes to --without-ssl option * Fixed quote parsing within strings * Bitmask fix in EDNS handling * Fixed non-fqdn domain name completion for rdata field domain names of length 1 * Fixed chain validation with SHA256 DS records 1.6.0 Additions: * Addition of an ldns-config script which gives cflags and libs values, for use in configure scripts for applications that use use ldns. Can be disabled with ./configure --disable-ldns-config * Added direct sha1, sha256, and sha512 support in ldns. With these functions, all NSEC3 functionality can still be used, even if ldns is built without OpenSSL. Thanks to OpenBSD, Steve Reid, and Aaron D. Gifford for the code. * Added reading/writing support for the SPF Resource Record * Base32 functions are now exported Bugfixes: * ldns_is_rrset did not go through the complete rrset, but only compared the first two records. Thanks to Olafur Gudmundsson for report and patch * Fixed a small memory bug in ldns_rr_list_subtype_by_rdf(), thanks to Marius Rieder for finding an patching this. * --without-ssl should now work. Make sure that examples/ and drill also get the --without-ssl flag on their configure, if this is used. * Some malloc() return value checks have been added * NSEC3 creation has been improved wrt to empty nonterminals, and opt-out. * Fixed a bug in the parser when reading large NSEC3 salt values. * Made the allowed length for domain names on wire and presentation format the same.

Since you cannot read QUESTION section RRs with this anymore, there is now a function called ldns_rr_new_question_frm_str() LIBRARY FEATURES: * DS RRs string representation now add bubblebabble in a comment (patch from Jakob Schlyter) * DLV RR type added * TCP fallback system has been improved * HMAC-SHA256 TSIG support has been added. * TTLS are now correctly set in NSEC(3) records when signing zones EXAMPLE TOOLS: * New example: ldns-revoke to revoke DNSKEYs according to RFC5011 * ldns-testpkts has been fixed and updated * ldns-signzone now has the option to not add the DNSKEY * ldns-signzone now has an (full zone only) opt-out option for NSEC3 * ldns-keygen can create HMAC-SHA1 and HMAC-SHA256 symmetric keys * ldns-walk output has been fixed * ldns-compare-zones has been fixed, and now has an option to show all differences (-a) * ldns-read-zone now has an option to print DNSSEC records only 1.3 Base library: * Added a new family of functions based around ldns_dnssec_zone, which is a new structure that keeps a zone sorted through an rbtree and links signatures and NSEC(3) records directly to their RRset. These functions all start with ldns_dnssec_ * ldns_zone_sign and ldns_zone_sign_nsec3 are now deprecated, but have been changed to internally use the new ldns_dnssec_zone_sign(_nsec3) * Moved some ldns_buffer functions inline, so a clean rebuild of applications relying on those is needed (otherwise you'll get linker errors) * ldns_dname_label now returns one extra (zero) byte, so it can be seen as an fqdn. * NSEC3 type code update for signing algorithms. * DSA key generation of DNSKEY RRs fixed (one byte too small). * Added support for RSA/SHA256 and RSA/SHA512, as specified in draft-ietf-dnsext-dnssec-rsasha256-04. The typecodes are not final, and this feature is not enabled by default. It can be enabled at compilation time with the flag --with-sha2 * Added 2wire_canonical family of functions that lowercase dnames in rdata fields in resource records of the types in the list in rfc3597 * Added base32 conversion functions. * Fixed DSA RRSIG conversion when calling OpenSSL Drill: * Chase output is completely different, it shows, in ascii, the relations in the trust hierarchy. Examples: * Added ldns-verify-zone, that can verify the internal DNSSEC records of a signed BIND-style zone file * ldns-keygen now takes an -a argument specifying the algorithm, instead of -R or -D. -a list show a list of supported algorithms * ldns-keygen now defaults to the exponent RSA_F4 instead of RSA_3 for RSA key generation * ldns-signzone now has support for HSMs * ldns-signzone uses the new ldns_dnssec_ structures and functions which improves its speed, and output; RRSIGS are now placed directly after their RRset, NSEC(3) records directly after the name they handle Contrib: * new contrib/ dir with user contributions * added compilation script for solaris (thanks to Jakob Schlyter) 28 Nov 2007 1.2.2: * Added support for HMAC-MD5 keys in generator * Added a new example tool (written by Ondrej Sury): ldns-compare-zones * ldns-keygen now checks key sizes for rfc conformance * ldns-signzone outputs SSL error if present * Fixed manpages (thanks to Ondrej Sury) * Fixed Makefile for -j * Fixed a $ORIGIN error when reading zones * Fixed another off-by-one error 03 Oct 2007 1.2.1: * Fixed an offset error in rr comparison * Fixed ldns-read-zone exit code * Added check for availability of SHA256 hashing algorithm * Fixed ldns-key2ds -2 argument * Fixed $ORIGIN bug in .key files * Output algorithms as an integer instead of their mnemonic * Fixed a memory leak in dnssec code when SHA256 is not available * Updated fedora .spec file 11 Apr 2007 1.2.0: * canonicalization of rdata in DNSSEC functions now adheres to the rr type list in rfc3597, not rfc4035, which will be updated (see http://www.ops.ietf.org/lists/namedroppers/namedroppers.2007/msg00183.html) * ldns-walk now support dnames with maximum label length * ldnsd now takes an extra argument containing the address to listen on * signing no longer signs every rrset with KSK's, but only the DNSKEY rrset * ported to Solaris 10 * added ldns_send_buffer() function * added ldns-testpkts fake packet server * added ldns-notify to send NOTIFY packets * ldns-dpa can now accurately calculate the number of matches per second * libtool is now used for compilation too (still gcc, but not directly) * Bugfixes: - TSIG signing buffer size - resolv.conf reading (comments) - dname comparison off by one error - typo in keyfetchers output file name fixed (a . too much) - fixed zone file parser when comments contain ( or ) - fixed LOC RR type - fixed CERT RR type Drill: * drill prints error on failed axfr. * drill now accepts mangled packets with -f * old -c option (use tcp) changed to -t * -c option to specify alternative resolv.conf file added * feedback of signature chase improved * chaser now stops at root when no trusted keys are found instead of looping forever trying to find the DS for . * Fixed bugs: - wildcard on multiple labels signature verification - error in -f packet writing for malformed packets - made KSK check more resilient 7 Jul 2006: 1.1.0: ldns-team * Added tutorials and an introduction to the documentation * Added include/ and lib/ dirs so that you can compile against ldns without installing ldns on your system * Makefile updates * Starting usage of assert throughout the library to catch illegal calls * Solaris 9 testing was carried out. Ldns now compiles on that platform; some gnuism were identified and fixed. * The ldns_zone structure was stress tested. The current setup (ie. just a list of rrs) can scale to zone file in order of megabytes. Sorting such zone is still difficult. * Reading multiline b64 encoded rdata works. * OpenSSL was made optional, configure --without-ssl. Ofcourse all dnssec/tsig related functions are disabled * Building of examples and drill now happens with the same defines as the building of ldns itself. * Preliminary sha-256 support was added. Currently is your OpenSSL supports it, it is supported in the DS creation. * ldns_resolver_search was implemented * Fixed a lot of bugs Drill: * -r was killed in favor of -o
which allows for a header bits setting (and maybe more in the future) * DNSSEC is never automatically set, even when you query for DNSKEY/RRSIG or DS. * Implement a crude RTT check, it now distinguishes between reachable and unreachable. * A form of secure tracing was added * Secure Chasing has been improved * -x does a reverse lookup for the given IP address Examples: * ldns-dpa was added to the examples - this is the Dns Packet Analyzer tool. * ldnsd - as very, very simple nameserver impl. * ldns-zsplit - split zones for parallel signing * ldns-zcat - cat split zones back together * ldns-keyfetcher - Fetches DNSKEY records with a few (non-strong, non-DNSSEC) anti-spoofing techniques. * ldns-walk - 'Walks' a DNSSEC signed zone * Added an all-static target to the makefile so you can use examples without installing the library * When building in the source tree or in a direct subdirectory of the build dir, configure does not need --with-ldns=../ anymore Code: * All networking code was moved to net.c * rdata.c: added asserts to the rdf set/get functions * const keyword was added to pointer arguments that aren't changed API: Changed: * renamed ldns/dns.h to ldns/ldns.h * ldns_rr_new_frm_str() is extended with an extra variable which in common use may be NULL. This trickles through to: o ldns_rr_new_frm_fp o ldns_rr_new_frm_fp_l Which also get an extra variable Also the function has been changed to return a status message. The compiled RR is returned in the first argument. * ldns_zone_new_frm_fp_l() and ldns_zone_new_frm_fp() are changed to return a status msg. * ldns_key_new_frm_fp is changed to return ldns_status and the actual key list in the first argument * ldns_rdata_new_frm_fp[_l]() are changed to return a status. the rdf is return in the first argument * ldns_resolver_new_frm_fp: same treatment: return status and the new resolver in the first argument * ldns_pkt_query_new_frm_str(): same: return status and the packet in the first arg * tsig.h: internal used functions are now static: ldns_digest_name and ldns_tsig_mac_new * ldns_key_rr2ds has an extra argument to specify the hash to use. * ldns_pkt_rcode() is renamed to ldns_pkt_get_rcode, ldns_pkt_rcode is now the rcode type, like ldns_pkt_opcode New: * ldns_resolver_searchlist_count: return the searchlist counter * ldns_zone_sort: Sort a zone * ldns_bgsend(): background send, returns a socket. * ldns_pkt_empty(): check is a packet is empty * ldns_rr_list_pop_rr_list(): pop multiple rr's from another rr_list * ldns_rr_list_push_rr_list(): push multiple rr's to an rr_list * ldns_rr_list_compare(): compare 2 ldns_rr_lists * ldns_pkt_push_rr_list: rr_list equiv for rr * ldns_pkt_safe_push_rr_list: rr_list equiv for rr Removed: * ldns_resolver_bgsend(): was not used in 1.0.0 and is not used now * ldns_udp_server_connect(): was faulty and isn't really part of the core ldns idea any how. * ldns_rr_list_insert_rr(): obsoleted, because not used. * char *_when was removed from the ldns_pkt structure 18 Oct 2005: 1.0.0: ldns-team * Committed a patch from HÃ¥kan Olsson * Added UPDATE support (Jakob Schlyter and HÃ¥kan Olsson) * License change: ldns is now BSD licensed * ldns now depends on SSL * Networking code cleanup, added (some) server udp/tcp support * A zone type is introduced. Currently this is a list of RRs, so it will not scale well. * [beta] Zonefile parsing was added * [tools] Drill was added to ldns - see drill/ * [tools] experimental signer was added * [building] better check for ssl * [building] major revision of build system * [building] added rpm .spec in packaging/ (thanks to Paul Wouters) * [building] A lot of cleanup in the build scripts (thanks to Jakob Schlyter and Paul Wouters) 28 Jul 2005: 0.70: ldns-team * [func] ldns_pkt_get_section now returns copies from the rrlists in the packet. This can be freed by the user program * [code] added ldns_ prefixes to function from util.h * [inst] removed documentation from default make install * Usual fixes in documentation and code 20 Jun 2005: 0.66: ldns-team Rel. Focus: drill-pre2 uses some functions which are not in 0.65 * dnssec_cd bit function was added * Zone infrastructure was added * Usual fixes in documentation and code 13 Jun 2005: 0.65: ldns-team * Repository is online at: http://www.nlnetlabs.nl/ldns/svn/ * Apply reference copying throughout ldns, except in 2 places in the ldns_resolver structure (._domain and ._nameservers) * Usual array of bugfixes * Documentation added * keygen.c added as an example for DNSSEC programming 23 May 2005: 0.60: ldns-team * Removed config.h from the header installed files (you're not supposed to include that in a library) * Further tweaking - DNSSEC signing/verification works - Assorted bug fixes and tweaks (memory management) May 2005: 0.50: ldns-team * First usable release * Basic DNS functionality works * DNSSEC validation works ldns-1.8.3/resolver.c0000664000175000017500000010742014276421036014047 0ustar willemwillem/* * resolver.c * * resolver implementation * * a Net::DNS like library for C * * (c) NLnet Labs, 2004-2006 * * See the file LICENSE for the license */ #include #include #include /* Access function for reading * and setting the different Resolver * options */ /* read */ uint16_t ldns_resolver_port(const ldns_resolver *r) { return r->_port;

.TH drill 1 "28 May 2006" .SH NAME drill \- get (debug) information out of DNS(SEC) .SH SYNOPSIS .B drill [ .IR OPTIONS ] .IR name [ .IR @server ] [ .IR type ] [ .IR class ] .SH DESCRIPTION \fBdrill\fR is a tool designed to get all sorts of information out of the DNS. It is specifically designed to be used with DNSSEC. .PP The name \fBdrill\fR is a pun on \fBdig\fR. With \fBdrill\fR you should be able get even more information than with \fBdig\fR. .PP If no arguments are given class defaults to 'IN' and type to 'A'. The server(s) specified in /etc/resolv.conf are used to query against. .PP \fIname\fR Ask for this name. .PP \fI@server\fR Send to query to this server. If not specified use the nameservers from \fI/etc/resolv.conf\fR. .PP \fItype\fR Ask for this RR type. If type is not given on the command line it defaults to 'A'. Except when doing a reverse lookup when it defaults to 'PTR'. .PP \fIclass\fR Use this class when querying. .SH SAMPLE USAGE \fBdrill mx miek.nl\fR Show the MX records of the domain miek.nl .TP \fBdrill \-S jelte.nlnetlabs.nl\fR Chase any signatures in the jelte.nlnetlab.nl domain. This option is only available when ldns has been compiled with openssl-support. .TP \fBdrill \-TD www.example.com\fR Do a DNSSEC (\-D) trace (\-T) from the rootservers down to www.example.com. This option only works when ldns has been compiled with openssl support. .TP \fBdrill \-s dnskey jelte.nlnetlabs.nl\fR Show the DNSKEY record(s) for jelte.nlnetlabs.nl. For each found DNSKEY record also print the DS record. .SH OPTIONS .TP \fB\-D Enable DNSSEC in the query. When querying for DNSSEC types (DNSKEY, RRSIG, DS and NSEC) this is \fInot\fR automatically enabled. .TP \fB\-T Trace \fIname\fR from the root down. When using this option the @server arguments is not used. .TP \fB\-S Chase the signature(s) of 'name' to a known key or as high up in the tree as possible. .TP \fB\-I \fIIPv4 or IPv6 address\fR Source address to query from. The source address has to be present on an interface of the host running drill. .TP \fB\-V \fIlevel\fR Be more verbose. Set level to 5 to see the actual query that is sent. .TP \fB\-Q Quiet mode, this overrules \-V. .TP \fB\-f \fIfile\fR Read the query from a file. The query must be dumped with \-w. .TP \fB\-i \fIfile\fR read the answer from the file instead from the network. This aids in debugging and can be used to check if a query on disk is valid. If the file contains binary data it is assumed to be a query in network order. .TP \fB\-w \fIfile\fR Write an answer packet to file. .TP \fB\-q \fIfile\fR Write the query packet to file. .TP \fB\-v Show drill's version. .TP \fB\-h Show a short help message. .SS QUERY OPTIONS .TP \fB\-4 Stay on ip4. Only send queries to ip4 enabled nameservers. .TP \fB\-6 Stay on ip6. Only send queries to ip6 enabled nameservers. .TP \fB\-a Use the resolver structure's fallback mechanism if the answer is truncated (TC=1). If a truncated packet is received and this option is set, drill will first send a new query with EDNS0 buffer size 4096. If the EDNS0 buffer size was already set to 512+ bytes, or the above retry also results in a truncated answer, the resolver structure will fall back to TCP. .TP \fB\-b \fIsize\fR Use size as the buffer size in the EDNS0 pseudo RR. .TP \fB\-c \fIfile\fR Use file instead of /etc/resolv.conf for nameserver configuration. .TP \fB\-d \fIdomain\fR When tracing (\-T), start from this domain instead of the root. .TP \fB\-t Use TCP/IP when querying a server .TP \fB\-k \fIkeyfile\fR Use this file to read a (trusted) key from. When this options is given \fBdrill\fR tries to validate the current answer with this key. No chasing is done. When \fBdrill\fR is doing a secure trace, this key will be used as trust anchor. Can contain a DNSKEY or a DS record. Alternatively, when DNSSEC enabled tracing (\fB-TD\fR) or signature chasing (\fB-S\fR), if \fB-k\fR is not specified, and a default trust anchor (@LDNS_TRUST_ANCHOR_FILE@) exists and contains a valid DNSKEY or DS record, it will be used as the trust anchor. .TP \fB\-o \fImnemonic\fR Use this option to set or unset specific header bits. A bit is set by using the bit mnemonic in CAPITAL letters. A bit is unset when the mnemonic is given in lowercase. The following mnemonics are understood by \fBdrill\fR: QR, qr: set, unset QueRy (default: on) AA, aa: set, unset Authoritative Answer (default: off) TC, tc: set, unset TrunCated (default: off) RD, rd: set, unset Recursion Desired (default: on) CD, cd: set, unset Checking Disabled (default: off) RA, ra: set, unset Recursion Available (default: off) AD, ad: set, unset Authenticated Data (default: off) Thus: \fB-o CD\fR, will enable Checking Disabled, which instructs the cache to not validate the answers it gives out. .TP \fB\-p \fIport\fR Use this port instead of the default of 53. .TP \fB\-r \fIfile\fR When tracing (\-T), use file as a root servers hint file. .TP \fB\-s When encountering a DNSKEY print the equivalent DS also. .TP \fB\-u Use UDP when querying a server. This is the default. .TP \fB\-w \fIfile\fR write the answer to a file. The file will contain a hexadecimal dump of the query. This can be used in conjunction with \-f. .TP \fB\-x Do a reverse lookup. The type argument is not used, it is preset to PTR. .TP \fB\-y \fI\fR specify named base64 tsig key, and optional an algorithm (defaults to hmac-md5.sig-alg.reg.int) .TP \fB\-z \fR don't randomize the nameserver list before sending queries. .SS EDNS QUERY OPTIONS .TP \fB\+nsid \fR When set, this EDNS option includes an EDNS name server ID request in the query. .SH "EXIT STATUS" The exit status is 0 if the looked up answer is secure and trusted, or insecure. The exit status is not 0 if the looked up answer is untrusted or bogus, or an error occurred while performing the lookup. .SH "FILES" .TP @LDNS_TRUST_ANCHOR_FILE@ The file from which trusted keys are loaded when no \fB-k\fR option is given. .SH "SEE ALSO" .LP unbound-anchor(8) .SH AUTHOR Jelte Jansen and Miek Gieben.

This file documents the changes. o When tracing (-T option) we use the local resolver (as specified in /etc/resolv.conf) to lookup names. This increases the speed dramatically, but you obviously need to be able to reach a recursive server/cache. Previously drill would try to resolve the names by itself. o Printing of DSs after DNSKEY records. Because we don't parse our own packets anymore, we cannot print the DS directly after the DNSKEY record. The DSs are now printed AFTER the packet. o The long options are removed. o The chase function has a different output, and will be subject to change in the near future. o The useless (for jokes only) -I option was dropped. FIXED: o the argument parsing is much smarter, the order doesn't matter (much) anymore ldns-1.8.3/drill/README0000664000175000017500000000045614276421036014031 0ustar willemwillemQUICK INSTALL GUIDE drill is a subdirectory in ldns.

To make life easier --------- we are using ldns' version numbering for drill from now on. --------- Sadly this means we GO BACKWARDS in the versions --------- This ChangeLog will not be updated anymore - all changes are --------- documented in ldns' ChangeLog 1.0-pre3: to be released: drill-team * Secure tracing works * Added section about DNSSEC in the manual page * Allow the class information to be given to do_chase() * Lint fixes for the code * Bugzilla was setup for drill * Bug #97 (drill); -S crash was fixed * Add -Q (quiet) flag was added. This suppresses output from drill. 1.0-pre2: 20 Jun 2005: drill-team * Second prerelease * Bugs where fix in the chasing functionality 1.0-pre1: 1 Jun 2005: drill-team * First drill release based on ldns * drill's core code is not much more simple, as all the difficult stuff is moved to ldns. * Much saner argument parsing ---------- Above Newer drill based on ldns -------------- ---------- Below Older drill with it's own DNS handling -------------- 0.9.2: Feb 3 2005: drill-team * Added two more options (borrowed from dig) --rd, don't set the RD bit in queries --fail, don't query the next nameserver on SERVFAIL * Fixed handling of obscure data types * Handle classes other the 'IN' when making a query * For people using FreeBSD: drill is now in the ports (Thanks to Jaap Akkerhuis) 0.9.1: Jan 5 2005: drill-team * Makefile tweaks * drill ns . works * re-check the root in when tracing * added handling for some lesser known types (including WKS) 0.9: Dec 6 2004: drill-team * big configure.ac and Makefile.in updates (made more general) * escapes in names argument and txt and dname data * gcc 2(.95) support * packet wire data is now checked for dangerous elements (like looping compression etc) * (Multiple) Octal char representation * Responses can be saved to file * 'Answers' can be read from file instead of server * Lots and lots of bugfixes and improvements 0.8.1: Oct 27 2004: Miek * configure.ac updates * secure resolving updates (still doesn't work) * printing additions - CERT RR supported - LOC RR support * All non supported RRs are handled as unknown * If no nameservers found in /etc/resolv.conf default to 127.0.0.1 * Various bugs fixed - Close sockets after using them - Some memory leaks were plugged 0.8: Oct 26 2004: Miek * Lots of features added. Drill is almost feature complete * Unknown RR's are supported * Numerous smaller updates in documentation * Numerous code cleanups * Dig is no longer needed to build drill 0.7: Oct 21 2004: Miek * reworked internal code * DNSSEC is working, except the secure resolving * build updates * more sane options parsing * more sane argument handling 0.6-alpha: Oct 2004: Jelte * No log 0.5-alpha: Sept 22 2004: Miek * most of the DNS stuff is working * moved to configure * tested on Linux/FreeBSD * fully IPV6 capable * new DNSSEC types supported * DNSSEC somewhat working * gcc => 3 is needed for building 0.4-alpha: Sept 9 2004: Miek * moved to autoconf for building * lots of various updates * really a workable program now 0.3-alpha: Sept 6 2004: Miek * IPv6 support * automatic secure resolving * --trace updates * --chase updates * more checks ldns-1.8.3/drill/drill_util.h0000664000175000017500000000223114276421036015456 0ustar willemwillem/* * util.h * util.c header file * in ldns * (c) 2005 NLnet Labs * * See the file LICENSE for the license * */ #ifndef _DRILL_UTIL_H_ #define _DRILL_UTIL_H_ #include /** * Read keys from filename and append to key_list. */ ldns_status read_key_file(const char *filename, ldns_rr_list *key_list, bool silently);

DESCRIPTION will be used for AC_DEFINEs. ACTION-IF-ENABLED # and ACTION-IF-NOT-ENABLED are the actions that will be run. A feature is # enabled by default, in order to change this behaviour use the # AX_CONFIG_FEATURE_DEFAULT_ENABLED and AX_CONFIG_FEATURE_DEFAULT_DISABLED # macros. # # A simple example: # # AX_CONFIG_FEATURE_DEFAULT_ENABLED # AX_CONFIG_FEATURE(feature_xxxxx, [turns on/off XXXXX support], # HAVE_XXXXX, [Define if you want XXXXX support]) # # ... # # AX_CONFIG_FEATURE_DEFAULT_DISABLED # AX_CONFIG_FEATURE(feature_yyyyy, [turns on/off YYYYY support], # HAVE_YYYYY, [Define if you want YYYYY support], # [enable_yyyyy="yes"], [enable_yyyyy="no"]) # AM_CONDITIONAL(YYYYY, [test "$enable_yyyyy" = "yes"]) # # AX_CONFIG_FEATURE_DEFAULT_ENABLED # AX_CONFIG_FEATURE(...) # # ... # # If you have lot of features and you want a verbose dumping of each user # selection use AX_CONFIG_FEATURE_VERBOSE. Use AX_CONFIG_FEATURE_SILENT in # order to remove a previously AX_CONFIG_FEATURE_VERBOSE. By default # features are silent. # # Use AX_CONFIG_FEATURE_ENABLE or AX_CONFIG_FEATURE_DISABLE in order to # enable or disable a specific feature. # # Another simple example: # # AS_IF([some_test_here],[AX_CONFIG_FEATURE_ENABLE(feature_xxxxx)],[]) # # AX_CONFIG_FEATURE(feature_xxxxx, [turns on/off XXXXX support], # HAVE_XXXXX, [Define if you want XXXXX support]) # AX_CONFIG_FEATURE(feature_yyyyy, [turns on/off YYYYY support], # HAVE_YYYYY, [Define if you want YYYYY support], # [enable_yyyyy="yes"], [enable_yyyyy="no"]) # # ... # # NOTE: AX_CONFIG_FEATURE_ENABLE() must be placed first of the relative # AX_CONFIG_FEATURE() macro ... # # LICENSE # # Copyright (c) 2008 Francesco Salvestrini # # This program is free software; you can redistribute it and/or modify it # under the terms of the GNU General Public License as published by the # Free Software Foundation; either version 2 of the License, or (at your # option) any later version. # # This program is distributed in the hope that it will be useful, but # WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Compilers include Clang and GCC; while platforms include Android, iOS, Linux, and OS X on AMD64, Aarch64, PowerPC and s390x hardware. Android is tested on armv7a, aarch64, x86 and x86_64. The Android recipes build and install OpenSSL, and then builds LDNS. The testing is tailored for Android NDK-r19 and above, and includes NDK-r20 and NDK-r21. Mips and Mips64 are not tested because they are no longer supported under current NDKs. iOS is tested for iPhoneOS, WatchOS, AppleTVOS, iPhoneSimulator, AppleTVSimulator and WatchSimulator. The testing uses Xcode 10 on OS X 10.13. The LDNS Travis configuration file `.travis.yml` does not use top-level keys like `os:` and `compiler:` so there is no matrix expansion. Instead LDNS specifies the exact job to run under the `jobs:` and `include:` keys. ## Typical recipe A typical recipe tests Clang and GCC on various hardware. The hardware includes AMD64, Aarch64, PowerPC and s390x. PowerPC is a little-endian platform, and s390x is a big-endian platform. There are pairs of recipes that are similar to the following. ``` - os: linux name: GCC on Linux, Aarch64 compiler: gcc arch: arm64 dist: bionic - os: linux name: Clang on Linux, Aarch64 compiler: clang arch: arm64 dist: bionic ``` OS X provides a single recipe to test Clang. GCC is not tested because GCC is an alias for Clang. ## Sanitizer builds Two sanitizer builds are tested using Clang and GCC, for a total of four builds. The first sanitizer is Undefined Behavior sanitizer (UBsan), and the second is Address sanitizer (Asan). The sanitizers are only run on AMD64 hardware. Note the environment includes `UBSAN=yes` or `ASAN=yes` for the sanitizer builds. The recipes are similar to the following. ``` - os: linux name: UBsan, GCC on Linux, Amd64 compiler: gcc arch: amd64 dist: bionic env: UBSAN=yes - os: linux name: UBsan, Clang on Linux, Amd64 compiler: clang arch: amd64 dist: bionic env: UBSAN=yes ``` When the Travis script encounters a sanitizer it uses different `CFLAGS` and configuration string. ``` if [ "$UBSAN" = "yes" ]; then export CFLAGS="-DNDEBUG -g2 -O3 -fsanitize=undefined -fno-sanitize-recover" bash test/test_ci.sh elif [ "$ASAN" = "yes" ]; then export CFLAGS="-DNDEBUG -g2 -O3 -fsanitize=address" bash test/test_ci.sh ... ``` ## Android builds Travis tests Android builds for the armv7a, aarch64, x86 and x86_64 architectures. The builds are trickier than other builds for several reasons. The testing requires installation of the Android NDK and SDK, it requires a cross-compile, and requires OpenSSL prerequisites. The Android cross-compiles also require care to set the Autotools triplet, the OpenSSL triplet, the toolchain path, the tool variables, and the sysroot. The discussion below detail the steps of the Android recipes. ### Android job The first step sets environmental variables for the cross-compile using the Travis job. A typical job with variables is shown below. ``` - os: linux name: Android armv7a, Linux, Amd64 compiler: clang arch: amd64 dist: bionic env: - ANDROID=yes - AUTOTOOLS_HOST=armv7a-linux-androideabi - OPENSSL_HOST=android-arm - ANDROID_CPU=armv7a - ANDROID_API=23 - ANDROID_PREFIX="$HOME/android$ANDROID_API-$ANDROID_CPU" - ANDROID_SDK_ROOT="$HOME/android-sdk" - ANDROID_NDK_ROOT="$HOME/android-ndk" ``` ### ANDROID_NDK_ROOT The second step for Android is to set the environmental variables `ANDROID_NDK_ROOT` and `ANDROID_SDK_ROOT`. This is an important step because the NDK and SDK use the variables internally to locate their own tools. Also see [Recommended NDK Directory?](https://groups.google.com/forum/#!topic/android-ndk/qZjhOaynHXc) on the android-ndk mailing list. (Many folks miss this step, or use incorrect variables like `ANDROID_NDK_HOME` or `ANDROID_SDK_HOME`). If you are working from a developer machine you probably already have the necessary tools installed. You should ensure `ANDROID_NDK_ROOT` and `ANDROID_SDK_ROOT` are set properly. ### Tool installation The second step installs tools needed for OpenSSL, Expat and LDNS. This step is handled in by the script `contrib/android/install_tools.sh`. The tools include curl, tar, zip, unzip and java. ``` before_script: - | if [ "$ANDROID" = "yes" ]; then ./contrib/android/install_tools.sh elif [ "$IOS" = "yes" ]; then ./contrib/ios/install_tools.sh fi ``` ### NDK installation The third step installs the NDK and SDK. This step is handled in by the script `contrib/android/install_ndk.sh`. The script uses `ANDROID_NDK_ROOT` and `ANDROID_SDK_ROOT` to place the NDK and SDK in the `$HOME` directory. If you are working from a developer machine you probably already have a NDK and SDK installed. ### Android environment The fourth step sets the Android cross-compile environment using the script `contrib/android/setenv_android.sh`. The script is `sourced` so the variables in the script are available to the calling shell. The script sets variables like `CC`, `CXX`, `AS` and `AR`; sets `CFLAGS` and `CXXFLAGS`; sets a `sysroot` so Android headers and libraries are found; and adds the path to the toolchain to `PATH`. `contrib/android/setenv_android.sh` knows which toolchain and architecture to select by inspecting environmental variables set by Travis for the job. In particular, the variables `ANDROID_CPU` and `ANDROID_API` tell `contrib/android/setenv_android.sh` which tools and libraries to select. The `contrib/android/setenv_android.sh` script specifies the tools in a `case` statement like the following. There is a case for each of the architectures armv7a, aarch64, x86 and x86_64. ``` armv8a|aarch64|arm64|arm64-v8a) CC="aarch64-linux-android$ANDROID_API-clang" CXX="aarch64-linux-android$ANDROID_API-clang++" LD="aarch64-linux-android-ld" AS="aarch64-linux-android-as" AR="aarch64-linux-android-ar" RANLIB="aarch64-linux-android-ranlib" STRIP="aarch64-linux-android-strip" CFLAGS="-funwind-tables -fexceptions" CXXFLAGS="-funwind-tables -fexceptions -frtti" ``` ### OpenSSL The fifth step builds OpenSSL. OpenSSL is built for iOS using the scripts `contrib/android/install_openssl.sh`. The script downloads, configures and installs the latest release version of the OpenSSL libraries. OpenSSL is configured with `--prefix="$ANDROID_PREFIX"` so the headers are placed in `$ANDROID_PREFIX/include` directory, and the libraries are placed in the `$ANDROID_PREFIX/lib` directory. `ANDROID_PREFIX` is the value `$HOME/android$ANDROID_API-$ANDROID_CPU`. The libraries will be installed in `$HOME/android23-armv7a`, `$HOME/android23-aarch64`, etc. For Autotools projects, the appropriate `PKG_CONFIG_PATH` is exported. `PKG_CONFIG_PATH` is an important variable. It is the userland equivalent to sysroot, and allows Autotools to find non-system headers and libraries for an architecture. Typical `PKG_CONFIG_PATH` are `$HOME/android23-armv7a/lib/pkgconfig` and `$HOME/android23-aarch64/lib/pkgconfig`. OpenSSL also uses a custom configuration file called `15-android.conf`. It is a copy of the OpenSSL's project file and located at `contrib/android/15-android.conf`. The LDNS version is copied to the OpenSSL source files after unpacking the OpenSSL distribution. The LDNS version has legacy NDK support removed and some other fixes, like `ANDROID_NDK_ROOT` awareness. The changes mean LDNS's `15-android.conf` will only work with LDNS, with NDK-r19 and above, and a properly set environment. OpenSSL is configured with `no-engine`. If you want to include OpenSSL engines then edit `contrib/android/install_openssl.sh` and remove the config option. ### Android build Finally, once OpenSSL are built, then the Travis script configures and builds LDNS. The recipe looks as follows. ``` elif [ "$ANDROID" = "yes" ]; then export AUTOTOOLS_BUILD="$(./config.guess)" export PKG_CONFIG_PATH="$ANDROID_PREFIX/lib/pkgconfig" ./contrib/android/install_ndk.sh source ./contrib/android/setenv_android.sh ./contrib/android/install_openssl.sh ./contrib/android/bootstrap_ldns.sh ./configure \ --build="$AUTOTOOLS_BUILD" \ --host="$AUTOTOOLS_HOST" \ --prefix="$ANDROID_PREFIX" \ --with-ssl="$ANDROID_PREFIX" \ --disable-gost \ --with-drill --with-examples make -j 2 make install ``` Travis only smoke tests an Android build using a compile, link and install. The self tests are not run. TODO: figure out how to fire up an emulator, push the tests to the device and run them. ### Android flags `contrib/android/setenv_android.sh` uses specific flags for `CFLAGS` and `CXXFLAGS`. They are taken from `ndk-build`, so we consider them the official flag set. It is important to use the same flags across projects to avoid subtle problems due to mixing and matching different flags. `CXXFLAGS` includes `-fexceptions` and `-frtti` because exceptions and runtime type info are disabled by default. `CFLAGS` include `-funwind-tables` and `-fexceptions` to ensure C++ exceptions pass through C code, if needed. Also see `docs/CPLUSPLUS-SUPPORT.html` in the NDK docs. To inspect the flags used by `ndk-build` for a platform clone ASOP's [ndk-samples](https://github.com/android/ndk-samples/tree/master/hello-jni) and build the `hello-jni` project. Use the `V=1` flag to see the full compiler output from `ndk-build`. ## iOS builds Travis tests iOS builds for the armv7a, armv7s and aarch64 architectures for iPhoneOS, AppleTVOS and WatchOS. iPhoneOS is tested using both 32-bit builds (iPhones) and 64-bit builds (iPads). Travis also tests compiles against the simulators. The builds are trickier than other builds for several reasons. The testing requires a cross-compile, and requires OpenSSL prerequisites. The iOS cross-compiles also require care to set the Autotools triplet, the OpenSSL triplet, the toolchain path, the tool variables, and the sysroot. The discussion below detail the steps of the iOS recipes. ### iOS job The first step sets environmental variables for the cross-compile using the Travis job. A typical job with variables is shown below. ``` - os: osx osx_image: xcode10 name: Apple iPhone on iOS, armv7 compiler: clang env: - IOS=yes - AUTOTOOLS_HOST=armv7-apple-ios - OPENSSL_HOST=ios-cross - IOS_SDK=iPhoneOS - IOS_CPU=armv7s - IOS_PREFIX="$HOME/$IOS_SDK-$IOS_CPU" ``` ### Tool installation The second step installs tools needed for OpenSSL, Expat and LDNS. This step is handled in by the script `contrib/ios/install_tools.sh`. The tools include autotools, curl and perl. The installation happens at the `before_script:` stage of Travis. ``` before_script: - | if [ "$ANDROID" = "yes" ]; then ./contrib/android/install_tools.sh elif [ "$IOS" = "yes" ]; then ./contrib/ios/install_tools.sh fi ``` ### iOS environment The third step sets the iOS cross-compile environment using the script `contrib/ios/setenv_ios.sh`. The script is `sourced` so the variables in the script are available to the calling shell. The script sets variables like `CC`, `CXX`, `AS` and `AR`; sets `CFLAGS` and `CXXFLAGS`; sets a `sysroot` so iOS headers and libraries are found; and adds the path to the toolchain to `PATH`. `contrib/ios/setenv_ios.sh` knows which toolchain and architecture to select by inspecting environmental variables set by Travis for the job. In particular, the variables `IOS_SDK` and `IOS_CPU` tell `contrib/ios/setenv_ios.sh` which tools and libraries to select. The `contrib/ios/setenv_ios.sh` script specifies the tools to use during the cross-compile. For Apple SDKs, the tool names are the same as a desktop. There are no special prefixes for the mobile tools. ``` CPP=cpp CC=clang CXX=clang++ LD=ld AS=as AR=ar RANLIB=ranlib STRIP=strip ``` If you are working from a developer machine you probably already have the necessary tools installed. ### OpenSSL The fourth step builds OpenSSL. OpenSSL is built for iOS using the scripts `contrib/ios/install_openssl.sh`. The script downloads, configures and installs the latest release version of the OpenSSL libraries. OpenSSL is configured with `--prefix="$IOS_PREFIX"` so the headers are placed in `$IOS_PREFIX/include` directory, and the libraries are placed in the `$IOS_PREFIX/lib` directory. `IOS_PREFIX` is the value `$HOME/$IOS_SDK-$IOS_CPU`. The scheme handles both iOS SDKs and cpu architectures so the pair receives a unique installation directory. The libraries will be installed in `$HOME/iPhoneOS-armv7s`, `$HOME/iPhoneOS-arm64`, `$HOME/iPhoneSimulator-i386`, etc. For Autotools projects, the appropriate `PKG_CONFIG_PATH` is exported. `PKG_CONFIG_PATH` is an important variable. It is the userland equivalent to sysroot, and allows Autotools to find non-system headers and libraries for an architecture. Typical `PKG_CONFIG_PATH` are `$HOME/iPhoneOS-armv7s/lib/pkgconfig` and `$HOME/iPhoneOS-arm64/lib/pkgconfig`. OpenSSL also uses a custom configuration file called `15-ios.conf`. It is a copy of the OpenSSL's project file and located at `contrib/ios/15-ios.conf`. The LDNS version is copied to the OpenSSL source files after unpacking the OpenSSL distribution. The changes mean LDNS's `15-ios.conf` will only work with LDNS and a properly set environment. OpenSSL is configured with `no-engine`. Engines require dynamic loading so engines are disabled permanently in `15-ios.conf`. ### iOS build Finally, once OpenSSL are built, then the Travis script configures and builds LDNS. The full recipe looks as follows. ``` elif [ "$IOS" = "yes" ]; then export AUTOTOOLS_BUILD="$(./config.guess)" export PKG_CONFIG_PATH="$IOS_PREFIX/lib/pkgconfig" source ./contrib/ios/setenv_ios.sh ./contrib/ios/install_openssl.sh ./contrib/ios/bootstrap_ldns.sh ./configure \ --build="$AUTOTOOLS_BUILD" --host="$AUTOTOOLS_HOST" \ --prefix="$IOS_PREFIX" \ --with-ssl="$IOS_PREFIX" --disable-gost \ --with-drill --with-examples make -j 2 make install ``` Travis only smoke tests an iOS build using a compile, link and install. The self tests are not run. TODO: figure out how to fire up an simulator, push the tests to the device and run them. ### iOS flags `contrib/ios/setenv_ios.sh` uses specific flags for `CFLAGS` and `CXXFLAGS`. They are taken from Xcode, so we consider them the official flag set. It is important to use the same flags across projects to avoid subtle problems due to mixing and matching different flags. ldns-1.8.3/packaging/0000775000175000017500000000000014276421036013762 5ustar willemwillemldns-1.8.3/packaging/libldns.pc.in0000664000175000017500000000044214276421036016342 0ustar willemwillemprefix=@prefix@ exec_prefix=@exec_prefix@ libdir=@libdir@ includedir=@includedir@ Name: ldns Description: Library for DNS programming URL: http://www.nlnetlabs.nl/projects/ldns Version: @PACKAGE_VERSION@ Requires: Libs: -L${libdir} -lldns Libs.private: @LDFLAGS@ Cflags: -I${includedir} ldns-1.8.3/packaging/fedora/0000775000175000017500000000000014276421036015222 5ustar willemwillemldns-1.8.3/packaging/fedora/ldns.spec0000664000175000017500000001475414276421036017051 0ustar willemwillem%{?!with_python: %global with_python 1} %if %{with_python} %{!?python_sitelib: %global python_sitelib %(%{__python} -c "from distutils.sysconfig import get_python_lib; print get_python_lib()")} %{!?python_sitearch: %global python_sitearch %(%{__python} -c "from distutils.sysconfig import get_python_lib; print get_python_lib(1)")} %endif Summary: Lowlevel DNS(SEC) library with API Name: ldns Version: 1.6.13 Release: 1%{?dist} License: BSD Url: http://www.nlnetlabs.nl/%{name}/ Source: http://www.nlnetlabs.nl/downloads/%{%name}/%{name}-%{version}.tar.gz Group: System Environment/Libraries BuildRoot: %{_tmppath}/%{name}-%{version}-%{release}-root-%(%{__id_u} -n) BuildRequires: perl, libpcap-devel, openssl-devel , gcc-c++, doxygen, # Only needed for builds from svn snapshot # BuildRequires: libtool, autoconf, automake %if %{with_python} BuildRequires: python-devel, swig %endif %description ldns is a library with the aim to simplify DNS programming in C.
