* dirmngr: Support the new WKD draft with the openpgpkey subdomain.Werner Koch2019-07-031-8/+56
| | | | | | | | | * dirmngr/server.c (proc_wkd_get): Implement new openpgpkey subdomain method. -- Signed-off-by: Werner Koch <[email protected]> (cherry picked from commit 914fa3be22bf8848a97a7dd405a040d6ef31e2fd)

| | | | | | | | | | | | | | | | | Summary: * dirmngr/crlcache.c (crl_cache_flush): Also deinit the cache. * dirmngr/server.c (hlp_flushcrls, cmd_flushcrls): New. (register_commands): Add FLUSHCRLS. -- This allows it to flush the CRL cache of a running dirmngr server. This can be useful to debug / analyze CRL issues.

* dirmngr: Prepare for updated WKD specs with ?l= paramWerner Koch2018-10-221-12/+21
| | | | | | | | | | | | | | | | | | * dirmngr/server.c (proc_wkd_get): Tack the raw local address to the request. -- We append the raw non-canonicalized local address part to the hash. Servers who serve the requests from static files will ignore the parameters and a test with posteo shows that also services using a database ignore the parameter. The general idea is that service providers may use their own canonicalization rules. The problem is that we currently filter the returned key for the full mail address and thus we will never see a key if the service did a different canonicalization than we. So consider this to be an experiment. Signed-off-by: Werner Koch <[email protected]> (cherry picked from commit 256a280c51f9ea862e4bfb0bb530c2a96f9088f9)

| | | | | | | | | | | | | * dirmngr/server.c (proc_wkd_get): Check the returned SRV record names to mitigate rogue DNS servers. -- I am not sure wether this really is very useful because the security relies on a trustworthy DNS system anyway. However, that check is easy enough to do. Signed-off-by: Werner Koch <[email protected]> (cherry picked from commit ebe727ef596eefebb5eff7d03a98649ffc7ae3ee)

Change all callers to provide the default value. * dirmngr/crlfetch.c (crl_fetch): Rewrite to make use of ks_http_fetch. -- The old code simply did not use https for downloading of CRLS. Instead it rewrote https to http under the assumption that the CRL service was also available without encryption. Note that a CRL is self-standing and thus it does not need to have extra authenticity as provided by TLS. These days we should not use any unencrypted content and thus this patch. Be aware that cacert.org give a https CRL DP but that currently redirects to to http! This is a downgrade attack which we detect and don't allow. The outcome is that it is right now not possible to use CAcert certificates. Signed-off-by: Werner Koch <[email protected]>

This is actually not the case and would be wrong because neither the truncating in libassuan or our escaping is not the Right Thing. In any case the functions need to be more robust and comply to the promised interface. Thus the code has been factored out to a helper function and N has been bumped up correctly and checked in all cases. For some uses this changes the behaviour in the error case (i.e. CR or LF passed): It will now always be C-escaped and not passed to libassuan which would truncate the line at the first LF.

If a standard WKD query returns no data, we queue a test to be run after the end of the session (so that we do not delay the calling client). This check tests whether the server responsible for the queried address has WKD at all enabled. The test is done by checking whether the "policy" file exists. We do not check the "submission-address" file because that is not necessary for the web key operation. The policy file is now required.

HTTP redirects are not taken in account because they may chnage at any time due to load balancing etc and not relevant for gpg which may use the URL to detect changes in the WKD results.

* dirmngr: Implement experimental SRV record lookup for WKD.Werner Koch2017-01-081-1/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * dirmngr/server.c (cmd_wkd_get): Support SRV records. -- This patch changes the way a WKD query is done. Now we first look for a SRV record for service "openpgpkey" and port "tcp" under the to-be-queried domain. If such a record was found and the target host matches the to-be-queried domain or is a suffix to that domain, that target host is used instead of the domain name. The SRV record also allows to change the port and obviously can be used for load-balancing. For example a query for the submission address of example.org with the SRV record specification _openpgpkey._tcp IN SRV 0 0 0 wkd.foo.org. IN SRV 0 0 0 wkd.example.net. IN SRV 0 0 4711 wkd.example.org. (queried using the name "_openpgpkey._tcp.example.org") would fetch from this URL: https://wkd.example.org:4711/.well-known/openpgpkey/submission-address Note that the first two SRV records won't be used because foo.org and example.net do not match example.org. We require that the target host is identical to the domain or be a subdomain of it. This is so that an attacker modifying the SRV records needs to setup a server in a sub-domain of the actual domain and can't use an arbitrary domain. Whether this is a sufficient requirement is not clear and needs further discussion. Signed-off-by: Werner Koch <[email protected]>

* dirmngr: Add option --standard-resolver.Werner Koch2016-12-011-3/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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]>
* dirmngr: Use a default keyserver if none is explicitly setDaniel Kahn Gillmor2016-11-171-1/+5
| | | | | | | | | | | | | | | | | | * configure.ac: Define DIRMNGR_DEFAULT_KEYSERVER. * dirmngr/server.c (ensure_keyserver): Use it if no keyservers are set. * doc/dirmngr.texi: Document this behavior. -- A user who doesn't specify a keyserver, but asks gnupg to fetch a key currently just gets a simple error messages "No keyserver available". If the user is asking to contact a keyserver, we should have a reasonable default, and not require them to fiddle with settings when they might not know what settings to choose. This patch makes the default hkps://hkps.pool.sks-keyservers.net. Signed-off-by: Daniel Kahn Gillmor <[email protected]>
* dirmngr: Add command to only load the swdb.Werner Koch2016-11-161-385/+17
| | | | | | | | | | | | | | | | | | | | | | | * dirmngr/loadswdb.c: New. * dirmngr/Makefile.am (dirmngr_SOURCES): Add that file. * dirmngr/server.c: Remove includes cpparray.h and exectool.h. (cmd_loadswdb): New. (parse_version_number,parse_version_string): Remove. (my_mktmpdir, cmp_version): Remove. (fetch_into_tmpdir): Remove. (struct verify_swdb_parm_s): Remove. (verify_swdb_status_cb): Remove. (cmd_versioncheck): Remove. (register_commands): Register LOADSWDB. Remove VERSIONCHECK. -- This change is required to to the new design where gpgconf does the version check w/o network access and only dirmngr is responsible for getting the swdb. In the next installment the loading will be triggered as needed. Signed-off-by: Werner Koch <[email protected]>
