* dirmngr: Allow for non-URL specified ldap keyservers.Werner Koch2021-06-167-168/+367
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * dirmngr/server.c (cmd_ldapserver): Strip an optional prefix. (make_keyserver_item): Handle non-URL ldap specs. * dirmngr/dirmngr.h (struct ldap_server_s): Add fields starttls, ldap_over_tls, and ntds. * dirmngr/ldapserver.c (ldapserver_parse_one): Add for an empty host string. Improve error messages for the non-file case. Support flags. * dirmngr/ks-action.c (ks_action_help): Handle non-URL ldap specs. (ks_action_search, ks_action_get, ks_action_put): Ditto. * dirmngr/ks-engine-ldap.c: Include ldapserver.h. (ks_ldap_help): Handle non-URL ldap specs. (my_ldap_connect): Add args r_host and r_use_tls. Rewrite to support URLs and non-URL specified keyservers. (ks_ldap_get): Adjust for changes in my_ldap_connect. (ks_ldap_search): Ditto. (ks_ldap_put): Ditto. -- The idea here is to unify our use of URLS or colon delimited ldap keyserver specification. The requirement for percent escaping, for example the bindname in an URLs, is cumbersome and prone to errors. This we allow our classic colon delimited format as an alternative. That format makes it also easy to specify flags to tell dirmngr whether to use starttls or ldap-over-tls. The code is nearly 100% compatible to existing specification. There is one ambiguity if the hostname for CRL/X509 searches is just "ldap"; this can be solved by prefixing it with "ldap:" (already implemented in gpgsm).

* dirmngr: For KS_SEARCH return the fingerprint also with LDAP.Werner Koch2021-05-191-48/+80
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * dirmngr/ks-engine-ldap.c (extract_keys): Return the fingerprint if available. (ks_ldap_search): Ditto. (extract_keys): Make sure to free the ldap values also in corner cases. (my_ldap_value_free): New. (ks_ldap_get): Ditto. (ks_ldap_search): Ditto. (my_ldap_connect): Ditto. -- For background see these comments from gpgme: /* The output for external keylistings in GnuPG is different from all the other key listings. We catch this here with a special preprocessor that reformats the colon handler lines. */ /* The format is: pub:<keyid>:<algo>:<keylen>:<creationdate>:<expirationdate>:<flags> as defined in 5.2. Machine Readable Indexes of the OpenPGP HTTP Keyserver Protocol (draft). Modern versions of the SKS keyserver return the fingerprint instead of the keyid. We detect this here and use the v4 fingerprint format to convert it to a key id. We want: pub:o<flags>:<keylen>:<algo>:<keyid>:<creatdate>:<expdate>:::::::: */ Regarding the freeing of values: I was not able to find a specification stating it is okay to pass NULL to ldap_value_free, thus the new wrapper. Also add robustness measures in case ldap_get_value returns an empty array. GnuPG-bug-id: 5441 Signed-off-by: Werner Koch <[email protected]>
* dirmngr: LDAP search by a mailbox now ignores revoked keys.Werner Koch2021-05-171-1/+2
| | | | | | | | | | | | | | | | | * dirmngr/ks-engine-ldap.c (keyspec_to_ldap_filter): Ignore revoked and disable keys in mail mode. -- The LDAP schema has a revoked and a disabled flag. The former will be set if a revoked key is uploaded; the latter can be set by other means. With this change a search by mailbox does not anymore return keys with these LDAP attributes set. This allows to better maintain a directory with multiple keys per mailbox. Doing the same for expired keys could also be done but requires more effort. Signed-off-by: Werner Koch <[email protected]>

Replace the use of the value 1 for the former quick arg. (KEYSERVER_IMPORT_FLAG_LDAP): New. * g10/keyserver.c (keyserver_get_chunk): Increase the reserved line length. * dirmngr/ks-action.c (ks_action_get): Add arg ldap_only. * dirmngr/server.c (cmd_ks_get): Add option --ldap. -- This change makes it easy to start working with gnupg: Just insert the smartcard or token provided to you and the first time you sign a message the public key associated with the current card will be imported and everything is set without any configuration. This works only with an LDAP directory because it can be expected that the public key has been put into the LDAP during card personalization. Of course an LDAP server needs to be configured; in a Windows AD domain this can be a mere "keyserver ldap:///" in dirmngr.conf. Other configured keyservers are ignored. Requirements for the card driver: The $SIGNKEYID attribute must exists and a query for the KEY-FPR attribute needs to return the OpenPGP fingerprint for that key. This is currently supported for OpenPGP cards and certain PKCS#15 cards. Signed-off-by: Werner Koch <[email protected]>

* dirmngr: Do not store the useless pgpSignerID in the LDAP.Werner Koch2020-12-143-10/+5
| | | | | | | | | | | | | | | | | | | | | | | * dirmngr/ks-engine-ldap.c (extract_attributes): Do not store the pgpSignerID. * g10/call-dirmngr.c (ks_put_inq_cb): Do not emit sig records. -- The pgpSignerID has no use in the LDAP and thus don't store it. David's idea back in 2004 was /* This bit is really for the benefit of people who store their keys in LDAP servers. It makes it easy to do queries for things like "all keys signed by Isabella". */ See-commit: 3ddd4410aef928827e1c8d4fb02c1ccd3f8eaea5 I consider this dangerous because such a query is not able to validate the signature, does not get revocation signatures, and also has no information about the validity of the signatures. Further many keys are spammed tehse days with faked signatures and it does not make sense to blow up the LDAP with such garbage. Signed-off-by: Werner Koch <[email protected]>

In fact some of the code is ugly and it would be better if we enhance Libgcrypt to guarantee that returned memory buffers via gcry_sexp_extract_param are allways Nul terminated and we should also enhance that function to directly extract into an unsigned int or char *.

It is better to consult only the list we have in gpgconf-comp.c to decide on whether an option should be displayed. Right, this might mess up thing if a newer gpgconf version is used with an older component, but we already print warnings in this case and in general we do not want to support this anymore - the times of gpg 1.4. and 2.0 are long over now.
