2016-12-15dirmngr: First patch to re-enable Tor support.Werner Koch1-32/+100
* dirmngr/dns-stuff.c (SOCKS_PORT, TOR_PORT, TOR_PORT2): New constants. (libdns_init): Start adding tor support. (resolve_name_libdns): Pass socks hosts to dns_res_open. (get_dns_cert_libdns): Ditto. (getsrv_libdns): Ditto. (get_dns_cname_libdns): Ditto. Signed-off-by: Werner Koch <[email protected]>
2016-12-14dirmngr: New configure option --disable-libdns.Werner Koch1-5/+52
* configure.ac: Add option --disable-libdns (USE_LIBDNS): New ac_subst and am_conditional. (USE_C99_CFLAGS): Set only if libdns is used. * dirmngr/Makefile.am (dirmngr_SOURCES): Move dns.c and dns.h to ... (dirmngr_SOURCES) [USE_LIBDNS0: here. (t_common_src): Ditto. * dirmngr/dirmngr.c (oRecursiveResolver): New constant. (opts): New option "--recursive-resolver". (parse_rereadable_options): Set option. * dirmngr/t-dns-stuff.c (main): Add option --recursive-resolver. * dirmngr/server.c (cmd_getinfo): Depend output of "dnsinfo" on the new variables. * dirmngr/dns-stuff.c: Include dns.h only if USE_DNSLIB is defined. Also build and call dnslib functions only if USE_DNSLIB is defined. (recursive_resolver): New var. (enable_recursive_resolver): New func. (recursive_resolver_p): New func. -- In case users run into problems building GnuPG, the configure option allows to disable that support and continue w/o Tor support using the system resolver. --recursive-resolver was easy enough to implement and may be useful in some situation. It does not fully work, though. Signed-off-by: Werner Koch <[email protected]>

However, our patch to ADNS that adds Tor support was never accepted upstream. Furthermore, there are other shortcomings that let us to consider alternatives.

2016-12-01dirmngr: Add option --standard-resolver.Werner Koch1-299/+394
* dirmngr/dirmngr.c (oStandardResolver): New constant. (opts): New option --standard-resolver. (parse_rereadable_options): Set option. * dirmngr/dns-stuff.c: Refactor all code to support the new option. (standard_resolver): New var. (enable_standard_resolver, standard_resolver_p): New func. * dirmngr/http.c (connect_server): Remove USE_DNS_SRV build conditional. * dirmngr/ks-engine-hkp.c (map_host): Ditto. * dirmngr/server.c (cmd_getinfo) <dnsinfo>: Take care of new option * configure.ac (HAVE_ADNS_IF_TORMODE): Remove var ADNSLIB. ac_define USE_ADNS in the adns checking code. Remove options --disable-dns-srv and --disable-dns-cert. Always look for the system resolver. Print warning if no system resolver was found. (USE_DNS_CERT, USE_DNS_SRV): Remove ac_defines. (HAVE_SYSTEM_RESOLVER): New ac_define. (USE_DNS_SRV): Remove am_conditional; not used anyway. -- This option allows for runtime switching to the system's standard resolver. This is mainly useful to work around possible bugs in the optional resolver libraries (as of now ADNS). Note that on Windows there is no code to use systems's resolver and thus for full functionality dirmngr must be build with a separate resolver. This patch also does way with configure options to disable the use of CERT and SRV records. Signed-off-by: Werner Koch <[email protected]>

2015-10-25dirmngr: Add workaround for broken getaddrinfo.Werner Koch1-1/+132
* dirmngr/dns-stuff.c (resolve_name_standard): On failure retry by first resolving the CNAME. (get_dns_cname): New. * dirmngr/t-dns-stuff.c (main): Add option --cname. -- At least the getaddrinfo implementation in glibc 2.19-13 from Debian returns EAI_NONAME if the CNAME points to a too long list of A/AAAA addresses. Looking at the wire the data is correctly returned from the server but getaddrinfo seems to get confused by truncation and retry. To fix this we resolve the CNAME again and call getaddrinfo again with the canonical name. Signed-off-by: Werner Koch <[email protected]>

2015-02-25gpg: Switch to a hash and CERT record based PKA system.Werner Koch1-6/+9
* common/dns-cert.c (get_dns_cert): Make r_key optional. * common/pka.c: Rewrite for the new hash based lookup. * common/t-pka.c: New. * configure.ac: Remove option --disable-dns-pka. (USE_DNS_PKA): Remove ac_define. * g10/getkey.c (parse_auto_key_locate): Always include PKA. -- Note that although PKA is now always build, it will only work if support for looking up via DNS has not been disabled. The new PKA only works with the IPGP DNS certtype and shall be used only to retrieve the fingerprint and optional the key for the first time. Due to the security problems with DNSSEC the former assumption to validate the key using DNSSEC is not anymore justified. Instead an additional layer (e.g. Trust-On-First-Use) needs to be implemented to track change to the key. Having a solid way of getting a key matching a mail address is however a must have. More work needs to go into a redefinition of the --verify-options pka-lookups and pka-trust-increase. The auto-key-locate mechanism should also be able to continue key fetching with another methods once the fingerprint has been retrieved with PKA. Signed-off-by: Werner Koch <[email protected]>

* common/dns-cert.c (get_dns_cert): Remove cruft. -- GnuPG-bug-id: 1850 Signed-off-by: Werner Koch <[email protected]>
2015-02-11Use inline functions to convert buffer data to scalars.Werner Koch1-9/+11
* common/host2net.h (buf16_to_ulong, buf16_to_uint): New. (buf16_to_ushort, buf16_to_u16): New. (buf32_to_size_t, buf32_to_ulong, buf32_to_uint, buf32_to_u32): New. -- Commit 91b826a38880fd8a989318585eb502582636ddd8 was not enough to avoid all sign extension on shift problems. Hanno Böck found a case with an invalid read due to this problem. To fix that once and for all almost all uses of "<< 24" and "<< 8" are changed by this patch to use an inline function from host2net.h. Signed-off-by: Werner Koch <[email protected]>
2014-11-07build: Improve test for ADNSWerner Koch1-3/+0
* configure.ac <adns>: Use adns_free as probe function for libadns. (HAVE_ADNS_FREE): Remove bogus tests to set this and remove the macro. (ADNSLIBS): Do not ac_subst - it is only used within configure. -- adns_free is required on Windows anyway (for robustness reasons) and it has been around for so long now that we do not need a separate test. An upstream adns 1.5 has meanwhile been release but I doubt that this has the required Windows code - and it is not libtool based anyway.
