2019-09-06gpg: expand GPG groups when resolving a keyStephan Mueller5-52/+99
* g10/expand-group.c: New * g10/pkclist.c: Extract expand_group and expand_id into expand-group.c. * g10/keydb.h: Add prototypes of expand_id and expand_group. * g10/getkey.c: Use expand_group before resolving key references. * g10/Makefile.am: Compile expand-group.c. -- When searching a key by its name, try to expand the provided name in case it is a GPG group reference. This GPG group resolution is performed before the individual keys are verified. This allows key listing using a GPG group reference. In particular, this modification fixes the encryption to group support in KDE's Kmail which is broken since version 18.04. Signed-off-by: Stephan Mueller <[email protected]> - Changed new filename to use a dash instead of an underscore. - Indendation changes. Signed-off-by: Werner Koch <[email protected]>

2019-09-05gpg: Prepare parser for the new attestation certificates.Werner Koch3-14/+57
* common/openpgpdefs.h (SIGSUBPKT_ATTST_SIGS): New. * g10/keydb.h (IS_ATTST_SIGS): New. (IS_CERT): Include the new one. * g10/sign.c (mk_notation_policy_etc): Do not put notations into attestation key signatures. * g10/parse-packet.c (dump_sig_subpkt): Add new arg digest_algo. Print the attestation sigs. (parse_one_sig_subpkt): Support SIGSUBPKT_ATTST_SIGS. (can_handle_critical): Ditto. (enum_sig_subpkt): Pass digest algo to dump_sig_subpkt. -- This change allows to list the new subpacket with --list-packets. Example output: :signature packet: algo 22, keyid C694723A1370EAB1 version 4, created 1567097576, md5len 0, sigclass 0x16 digest algo 8, begin of digest ff 0c hashed subpkt 2 len 4 (sig created 2019-08-29) hashed subpkt 37 len 32 (attst-sigs: 1 A794C6E9CCFE2F34C67E07[...]) hashed subpkt 33 len 21 (issuer fpr v4 156A3872[...]) subpkt 16 len 8 (issuer key ID C694723A1370EAB1) data: [256 bits] data: [256 bits] GnuPG-bug-id: 4694 Signed-off-by: Werner Koch <[email protected]>
2019-09-05gpg: Rework the signature subpacket iteration function.Werner Koch12-114/+114
* g10/parse-packet.c (enum_sig_subpkt): Replace first arg by two args so that the entire signature packet is available. Change all callers. (parse_sig_subpkt): Ditto. -- This patch is a prerequisite to support the new attestation key signatures. Signed-off-by: Werner Koch <[email protected]>
2019-08-23gpg,sm: Implement keybox compression run and release lock in gpgsmWerner Koch1-2/+15
* g10/keydb.c (keydb_add_resource): Call keybox_compress. * sm/keydb.c (keydb_add_resource): Release the lock after a compress. -- Note that in gpgsm we already did the compress run but we didn't released the lock on the file. This might have been a reason for some strange hangs. GnuPG-bug-id: 4644 Signed-off-by: Werner Koch <[email protected]>
2019-08-23gpg: Allow --locate-external-key even with --no-auto-key-locate.Werner Koch3-1/+35
* g10/getkey.c (akl_empty_or_only_local): New. * g10/gpg.c (DEFAULT_AKL_LIST): New. (main): Use it here. (main) <aLocateExtKeys>: Set default AKL if none is set. -- This better matches the expectations of the user. The used list in this case is the default list ("local,wkd") with local ignored by the command anyway. GnuPG-bug-id: 4662 Signed-off-by: Werner Koch <[email protected]>
2019-08-23gpg: Silence some warning messages during -Kv.Werner Koch3-10/+17
* g10/options.h (glo_ctrl): Add flag silence_parse_warnings. * g10/keylist.c (list_all): Set that during secret key listsings. * g10/parse-packet.c (unknown_pubkey_warning): If new flag is set do not print info message normally emitted inh verbose mode. (can_handle_critical_notation, enum_sig_subpkt): Ditto. (parse_signature, parse_key, parse_attribute_subpkts): Ditto. -- Those messages are annoying because they might be emitted due to parsing public keys which are latter not shows because the secret part is missing. No functional regressions are expected because --verbose should not change anything. Note that this suppression is only done if no arguments are given to the command; that is if a listing of the entire keyring is requested. Thus to see the earnings anyway, a listing of a single or group of keys can be requested. GnuPG-bug-id: 4627 Signed-off-by: Werner Koch <[email protected]>
2019-08-23gpg: Do not show two informational diagnostics with quiet.Werner Koch2-2/+7
* g10/trustdb.c (verify_own_keys): Silence informational diagnostic. -- This silences these notes with --quiet gpg: Note: RFC4880bis features are enabled. gpg: key EE65E8C75D41FD1D marked as ultimately trusted GnuPG-bug-id: 4634 Signed-off-by: Werner Koch <[email protected]>
2019-08-22gpg: Extend --quick-gen-key for creating keys from a card.Werner Koch1-58/+261
* g10/keygen.c (parse_key_parameter_part): Add arg R_KEYGRIP and support the special algo "card". (parse_key_parameter_string): Add args R_KEYGRIP and R_SUBKEYGRIP. Handle the "card" algo. Adjust callers. (parse_algo_usage_expire): Add arg R_KEYGRIP. (quickgen_set_para): Add arg KEYGRIP and put it into the parameter list. (quick_generate_keypair): Handle algo "card". (generate_keypair): Also handle the keygrips as returned by parse_key_parameter_string. (ask_algo): Support ed25519 from a card. -- Note that this allows to create a new OpenPGP key from an initialized OpenPGP card or from any other supported cards. It has been tested with the TCOS Netkey card. Right now a stub file for the cards might be needed; this can be achieved by running "gpgsm --learn" with the card plugged in.

This option allows to revert this in case of use use cases which expected the former behaviour. Signed-off-by: Werner Koch <[email protected]> (cherry picked from commit c185f6dfbd1bfd809369da789239a371e9d1610e) This was first added to the 2.2 branch.

* g10/mainproc.c (check_sig_and_print): Print a hint on how to make use of the preferred keyserver. Remove keyserver lookup just by the keyid.

When c->dek == NULL, put GPG_ERR_NO_SECKEY only when not set. * g10/pubkey-enc.c (get_session_key): Set k->result by the result of get_it.

2019-07-04gpg: Add "self-sigs-only" and "import-clean" to the keyserver options.Werner Koch1-1/+3
* g10/gpg.c (main): Change default. -- Due to the DoS attack on the keyeservers we do not anymore default to import key signatures. That makes the keyserver unsuable for getting keys for the WoT but it still allows to retriev keys - even if that takes long to download the large keyblocks.

Pass on to get_best_pubkey_byname. -- This new command is a shortcut for --auto-key-locate nodefault,clear,wkd,... --locate-key and uses the default or configured AKL list but does so without local.

* g10/options.h (IMPORT_SELF_SIGS_ONLY): New. * g10/import.c (parse_import_options): Add option "self-sigs-only". (read_block): Handle that option. -- This option is intended to help against importing keys with many bogus key-signatures. It has obvious drawbacks and is not a bullet-proof solution because a self-signature can also be faked and would be detected only later.

The translator may not understand them correctly and the use support can't immediately locate the problem because it needs to be reverse translated.

2019-05-17gpg: Improve the photo image viewer selection.Werner Koch2-27/+99
* g10/exec.c (w32_system): Add "!ShellExecute" special. * g10/photoid.c (get_default_photo_command): Use the new ShellExecute under Windows and fallbac to 'display' and 'xdg-open' in the Unix case. (show_photos): Flush stdout so that the output is shown before the image pops up. -- For Unix this basically syncs the code with what we have in gpg 1.4. Note that xdg-open may not be used when running as root which we support here. For Windows we now use ShellExecute as this seems to be preferred over "cmd /c start"; however this does not solve the actual problem we had in the bug report. To solve that problem we resort to a wait parameter which defaults to 400ms. This works on my Windows-10 virtualized test box. If we can figure out which simple viewers are commonly installed on Windows we should enhance this patch to test for them. GnuPG-bug-id: 4334 Signed-off-by: Werner Koch <[email protected]>
