| | | | | | | | | | | | | | | | | | | | | | | * kbx/backend-sqlite.c (be_sqlite_rollback): New. (be_sqlite_commit): New. (be_sqlite_search): Take care of global transactions. (be_sqlite_store): Ditto. (be_sqlite_delete): Ditto. * kbx/frontend.c (kbxd_rollback, kbxd_commit): New. * kbx/keyboxd.h (opt): Add vars for transactions. * kbx/kbxserver.c (struct server_local_s): Add fields next_session and client_pid. (session_list): New var. (cmd_transaction): New. (register_commands): Register command. (kbxd_start_command_handler): Store pids and track sessions. Do a final rollback. -- This command is currently an experiment to allow a client to run everything in one session. Signed-off-by: Werner Koch <[email protected]>
* kbx: Initial support for an SQLite backendWerner Koch2020-01-021-8/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * kbx/backend-sqlite.c: New. * kbx/Makefile.am (keyboxd_SOURCES): Add it. (keyboxd_CFLAGS, keyboxd_LDADD): Add SQLite flags. * kbx/backend.h (enum database_types): Add DB_TYPE_SQLITE. (be_sqlite_local_t): New typedef. (struct db_request_part_s): Add field besqlite. * kbx/backend-support.c (strdbtype): Add string for DB_TYPE_SQLITE. (be_generic_release_backend): Support SQLite. (be_release_request): Ditto. (be_find_request_part): Ditto. (is_x509_blob): Rename to ... (be_is_x509_blob): this and make global. * kbx/frontend.c (kbxd_set_database): Detect ".db" suffix and use that for SQLite. (kbxd_search): Support SQLite (kbxd_store): Ditto. (kbxd_delete): Ditto. * kbx/frontend.h (kbxd_store_modes): Move to ... * kbx/keyboxd.h (enum kbxd_store_modes): here. * kbx/keyboxd.c (main): USe pubring.db for now. This is a temporary hack. * kbx/backend-kbx.c (be_kbx_delete): Remove unused var cert. -- Take care: This is not finished and in particular filling the database takes quite long.

* kbx: Change keyboxd to work only with one database.Werner Koch2019-12-231-2/+2
| | | | | | | | | | | | | | | | | | * kbx/frontend.c (the_database): New var. (db_desc_t): Remove. (kbxd_add_resource): Renamed to ... (kbxd_set_database): this. Simplify. (kbxd_search): Change to use only one database. (kbxd_store): Ditto. (kbxd_delete): Ditto. -- The original implementation was way to complicated and would have only brought back the problems deciding which database to use for each key. The new scheme used one configured database and only that. That database needs to be set right at the start. Signed-off-by: Werner Koch <[email protected]>

* kbx: Redefine the UBID which is now the primary fingerprint.Werner Koch2019-11-281-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * common/util.h (UBID_LEN): New. Use it at all places. * kbx/keybox-blob.c (create_blob_finish): Do not write the UBID item. * kbx/keybox-dump.c (print_ubib): Remove. (_keybox_dump_blob): Do not print the now removed ubid flag. * kbx/keybox-search-desc.h (struct keydb_search_desc): Use constants for the size of the ubid and grip. * kbx/keybox-search.c (blob_cmp_ubid): New. (has_ubid): Make it a simple wrapper around blob_cmp_ubid. (keybox_get_data): Add arg 'r_ubid'. * kbx/frontend.h (enum kbxd_store_modes): New. * kbx/kbxserver.c (cmd_store): Add new option --insert. * kbx/backend-cache.c (be_cache_initialize): New. (be_cache_add_resource): Call it here. * kbx/backend-kbx.c (be_kbx_seek): Remove args 'fpr' and 'fprlen'. (be_kbx_search): Get the UBID from keybox_get_data. * kbx/backend-support.c (be_fingerprint_from_blob): Replace by ... (be_ubid_from_blob): new. Change all callers. * kbx/frontend.c (kbxd_add_resource): Temporary disable the cache but use the new cache init function. (kbxd_store): Replace arg 'only_update' by 'mode'. Seek using the ubid. Take care of the mode. -- It turned out that using the hash of the entire blob was not helpful. Thus we redefine the Unique-Blob-ID (UBID) as the primary fingerprint of the blob. In case this is a v5 OpenPGP key a left truncated version of the SHA-256 hash is used; in all other cases the full SHA-1 hash. Using a SHA-256 hash does not make sense because v4 keys are and will for some time be the majority of keys and thus padding them with zeroes won't make any difference. Even if fingerprint collisions can eventually be created we will assume that the keys are bogus and that it does not make sense to store its twin also in our key storage. We can also easily extend the update code to detect a collision and reject the update. Signed-off-by: Werner Koch <[email protected]>
