2016-12-20dirmngr: New option --resolver-timeout.Werner Koch1-3/+30
* dirmngr/dns-stuff.c (DEFAULT_TIMEOUT): New. (opt_timeout): New var. (set_dns_timeout): New. (libdns_res_open): Set the default timeout. (libdns_res_wait): Use configurable timeout. (resolve_name_libdns): Ditto. * dirmngr/dirmngr.c (oResolverTimeout): New const. (opts): New option --resolver-timeout. (parse_rereadable_options): Set that option. (main) <aGPGConfList>: Add --nameserver and --resolver-timeout. * tools/gpgconf-comp.c (gc_options_dirmngr): Add --resolver-timeout and --nameserver. * dirmngr/http.c (connect_server): Fix yesterday introduced bug in error diagnostic. -- This timeout is a pretty crude thing because libdns has a few other internal timeouts as well.

2016-12-19dirmngr: Fix problems with the getsrv function.Werner Koch1-23/+66
* dirmngr/dns-stuff.c (opt_debug, opt_verbose): New vars. (set_dns_verbose): New func. (libdns_switch_port_p): Add debug output. (resolve_dns_name): Ditto. (get_dns_cert): Ditto. (get_dns_cname): Ditto. (getsrv_libdns, getsrv_standard): Change SRVCOUNT to an unsigend int. (getsrv): Rename to ... ((get_dns_srv): this. Add arg R_COUNT and return an error. Add debug output. * dirmngr/http.c: Adjust for chnaged getsrv(). * dirmngr/ks-engine-hkp.c (map_host): Ditto. * dirmngr/t-dns-stuff.c (main): Ditto. Call set_dns_verbose. * dirmngr/dirmngr.c (parse_rereadable_options): Call set_dns_verbose. -- Due to our switch to Libdns getsrv didn't worked correctly because it returned -1 for an NXDOMAIN. However, it is perfectly okay to have no SRV record and thus we change the way this function is called to be aligned with the other functions and also map NXDOMAIN to a zero SRV record count.

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]>

(get_dns_cert): Use DNS resolver at 8.8.8.8 in tor-mode. * dirmngr/server.c (cmd_dns_cert): If supported allow DNS requests.
2015-10-06dirmngr: Improve DNS code to retrieve arbitrary records.Werner Koch1-3/+52
* dirmngr/dns-cert.c (get_dns_cert): Add hack to retrieve arbitrary resource records. * dirmngr/dns-cert.h (DNS_CERTTYPE_RRBASE): New. (DNS_CERTTYPE_RR61): New. -- This has been tested with ADNS on Unix and with the standard resolver. Because ADNS works it should also work on Windows. Signed-off-by: Werner Koch <[email protected]>

* dirmngr/dns-cert.c (get_dns_cert) [!USE_ADNS]: Change loop to allow adding more resource types.
2015-04-23gpg: Move all DNS access to Dirmngr.Werner Koch1-9/+23
* common/dns-cert.h: Move to ../dirmngr/. * common/dns-cert.c: Move to ../dirmngr/. Change args to return the key as a buffer. * common/t-dns-cert.c: Move to ../dirmngr/. * common/pka.c, common/pka.h, common/t-pka.c: Remove. * dirmngr/server.c (data_line_cookie_write): Factor code out to data_line_write and make it a wrapper for that. (data_line_write): New. (cmd_dns_cert): New. (register_commands): Register new command. * g10/Makefile.am (LDADD): Remove DNSLIBS. * g10/call-dirmngr.c (dns_cert_parm_s): New.

(gpg_dirmngr_get_pka): New. * g10/gpgv.c (gpg_dirmngr_get_pka): New dummy function. * g10/keyserver.c (keyserver_import_cert): Replace get_dns_cert by gpg_dirmngr_dns_cert. (keyserver_import_pka): Replace get_pka_info by gpg_dirmngr_get_pka. * g10/mainproc.c: Include call-dirmngr.h. (pka_uri_from_sig): Add CTX arg. Replace get_pka_info by gpg_dirmngr_get_pka. -- With this patch gpg does not do any network access itself but uses dirmngr for that. Note that we need to keep linking to NETLIBS due to the logging code and because we need TCP for our socket emulation under Windows. Probably also required for Solaris etc. Signed-off-by: Werner Koch <[email protected]>
