| | | | | | | | | | | | | | * agent/call-daemon.c (daemon_start): Decision of connection/reuse of CTX and assignment to ->ctx should be done with the lock. -- When scdaemon is exiting and agent tries to spawn/connect/reconnect, there is a race condition between detecting finish of scd and spawn/connect/reconnect.

| | | | | | | | | | * agent/command.c (cmd_get_passphrase): Allow use in restricted mode but ignore the cacheid. -- The use case is symmetric encryption via the extra-socket. To avoid that the gpg running on the server has access to the cache we set the cache id to NULL so that the cache is not used at all.

(nvc_delete): Set flag. (nvc_set): Set flag unless value did not change. (nve_set): Add arg PK. Change the caller. * agent/findkey.c (agent_write_private_key): Update only if modified. -- This helps software which uses a file system watcher to track changes to private keys. In particular smartcard triggered changes are a problem for such software because this may at worst trigger another smartcard read. GnuPG-bug-id: 6829
* scd:openpgp: Return better error codes for the Reset Code.Werner Koch2023-10-061-6/+9

* agent: Do not overwrite a key file by a shadow key file.Werner Koch2023-05-261-90/+64
| | | | | | | | | | | | * agent/findkey.c (agent_write_private_key): Partly rewrite to align with 2.2 code and to make sure that we don't overwrite a real key. (is_shadowed_key): New. -- This change is now also needed in 2.4 due to the the former change "Create and use Token entries to track the display s/n". GnuPG-bug-id: 6386
* agent: Update key files by first writing to a temp file.Werner Koch2023-05-261-66/+97
| | | | | | | * agent/findkey.c (fname_from_keygrip): New. (agent_write_private_key): Use here. Use temp file for updating. (agent_update_private_key): Use fname_from_keygrip and use gnupg rename function instead of a vanilla rename.

* gpg: Fix writing ECDH keys to OpenPGP smartcards.Werner Koch2023-04-211-8/+59
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * agent/command.c (cmd_keytocard): Add new arg for ECDH params. * scd/app-openpgp.c (ecc_writekey): Use provided ECDH params to compute the fingerprint. * g10/call-agent.c (agent_keytocard): Add arg ecdh_param_str. * g10/keyid.c (ecdh_param_str_from_pk): New. * g10/card-util.c (card_store_subkey): Pass ECDH params to writekey. * g10/keygen.c (card_store_key_with_backup): Ditto. * scd/app-openpgp.c (store_fpr): Add arg update. (rsa_read_pubkey, ecc_read_pubkey): Add arg meta_update and avoid writing the fingerprint back to the card if not set. (read_public_key): Also add arg meta_update. (get_public_key): Do not pass it as true here... (do_genkey): ... but here. (rsa_write_key, ecc_writekey): Force string the fingerprint. -- The problem showed up because in 2.4 we changed the standard ECDH parameter some years ago. Now when trying to write an ECDH key created by 2.2 with 2.4 to an openpgp card, scdaemon computes a wrong fingerprint and thus gpg was not able to find the key again by fingerprint. The patch also avoids updating the stored fingerprint in certain situations. This fix is somewhat related to GnuPG-bug-id: 6378
* ssh: Allow to prefer on-disk keys over active card keys.Werner Koch2023-04-182-6/+20
| | | | | | | | * agent/command-ssh.c (ssh_send_available_keys): Redefine the order of keys. -- GnuPG-bug-id: 6212

(istrusted_internal): Emit TRUSTLISTFLAG status line. * sm/gpgsm.h (struct rootca_flags_s): Add field de_vs. * sm/call-agent.c (istrusted_status_cb): Detect the flags. * sm/sign.c (write_detached_signature): Remove unused vars. -- Right now this flag has no effect; we first need to specify the exact behaviour. GnuPG-bug-id: 5079
* agent: New option --restricted for PRESET_PASSPHRASE.Werner Koch2023-03-272-3/+19
| | | | | | | | | | | | | | | | | | | * agent/command.c (cmd_preset_passphrase): Add option. * agent/preset-passphrase.c (oRestricted): New. (opts): Add option --restricted. (main): Set option. (preset_passphrase): Use option. -- We use a different cache for connections from the extra-socket. However, with gpg-preset-passphrase is only able to preset a passphrase into the regular cache. Further, a restricted connection may not use PRESET_PASSPHRASE. To solve this we add an new option to preset the passphrase into the "restricted" cache. For the gpg-preset-passphrase tool we also add the option --restricted. Note that this does not yet work with gpg-preset-passphrase --forget.
* agent: Make --disable-extended-key-format a dummy option.Werner Koch2023-03-1310-276/+152
| | | | | | | | | | | | | | | | | | | | | * agent/agent.h (opt): Remove enable_extended_key_format. * agent/gpg-agent.c (enum cmd_and_opt_values): Turn oDisableExtendedKeyFormat and oEnableExtendedKeyFormat into dummy options. * agent/protect.c (do_encryption): Remove arg use_ocb and corresponding code. (agent_protect): Ditto. Change all callers. * agent/findkey.c (agent_write_private_key): Simplify due to the removal of disable-extended-key-format. (write_extended_private_key): Fold into agent_write_private_key. -- This change is related to GnuPG-bug-id: 6386 but should have no visible effect except for the removal of option --disable-extended-key-format.

| | | | | | | | | | | | | | | * agent/findkey.c (agent_key_from_file): Check the error of read_key_file again. * agent/pkdecrypt.c (agent_pkdecrypt): Restore error if no card was found. Also remove useless condition. -- The first patch fixes a likely merge error. The second is about the actual return code: If we have no smardcard but simply try to decrypt with the current smartcard we should return the originla error code. GnuPG-bug-id: 5170 Fixes-commit: eda3c688fc2e85c7cd63029cb9caf06552d203b4
* ssh: Allow to define the order in which keys are returned.Werner Koch2023-02-014-63/+185

(free_key_array): New. (compare_key_collection_items): New. (ssh_send_available_keys): Rewrite to return the keys in the user given order. -- GnuPG-bug-id: 6212 We now first return the keys from active cards, followed by keys listed in sshcontrol, finally from those with the "Use-for-ssh" key attribute. Keys from active cards are returned sorted by their S/N. Keys from sshcontrol are returned in the order they are given in that file. Use-for-ssh keys are ordered by the value assigned to that key attribute. The values for the latter are clamped at 99999.
* common: Slight redefinition of nvc_get_boolean.Werner Koch2023-01-241-1/+2
| | | | | | | | | | * common/name-value.c (nvc_get_boolean): Rewrite. -- The function may now return a positive or negative number instead of just 1 for true. All callers were already prepared for this. GnuPG-bug-id: 6212
* agent: Allow arguments to "scd serialno" in restricted mode.Werner Koch2022-12-121-1/+1
| | | | | | | * agent/command.c (cmd_scd): Allow it. -- This is important because Scute uses "SCD SERIALNO --all".

(command_has_option): Ditto. * g10/build-packet.c (do_key): Implement mode 1003. * g10/parse-packet.c (parse_key): Ditto. * g10/options.h (EXPORT_MODE1003): New.o * g10/call-agent.c (agent_export_key): Add arg mode1003. * g10/export.c (parse_export_options): Add "mode1003" (secret_key_to_mode1003): New. (receive_seckey_from_agent): Add arg mode1003. (do_export_one_keyblock): Pass option down. -- This option allows to export a secret key in GnuPG's native format. Thus no re-encryption is required and further the public key parameters are also authenticated if a protection passphrase has been used. Note that --import is not yet able to handle this new mode. Although old version of GnuPG will bail out with "invalid packet" if a mode1003 exported secret key is seen.

* agent: Avoid blanks in the ssh key's comment.Werner Koch2022-11-021-0/+5
| | | | | | | | | | | | | | | | | | * agent/command-ssh.c (card_key_available): Replace blanks. -- For managing the authorized_key file of ssh it is convenient if the comment does not have any spaces. Thus we now return cardno:FFFE_50FF3D01 instead of cardno:FFFE 50FF3D01 Note that gpg --export-ssh-key uses the keyid as comment because it does not known the S/N of the card. Gpg-agent however does not know about OpenPGP and uses the s/n.
