| | | | | | | | | | | | | | | | | | | | | * g10/import.c (get_revocation_reason): New. (list_standalone_revocation): Extend function. -- Note that this function extends the "rvs" field signature-class (field 11) with the revocation reason. GPGME does not yet parse this but it can be expected that the comma delimiter does not break other parsers.

Hopefully all parsers meanwhile learned the lesson from other new fields and don't bail out on more fields than they know about.

* gpg: Fix import's repair-key duplicate signature detection.Werner Koch2018-06-072-5/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * g10/packet.h (PKG_siganture): Add field 'help_counter'. * g10/key-check.c (sig_comparison): Take care of HELP_COUNTER. (key_check_all_keysigs): De-duplicate on a per-block base. -- The key_check_all_keysigs first does a detection of duplicate signature. This is done over all signatures at once. The problem here is for example: key uid_1 sig_uid_1.1 sig_uid_1.2 subkey_1 sig_sub_1.1 subkey_2 sig_sub_2.1 sig_sub_2.2 (duplicate of sig_sub_1.1) Now the de-duplication deletes the first signature and keeps the second. That works in most cases for foreign signature on userids but in the above constellation the code simply removes sig_sub_1.1 so that subkey_1 has no binding signature anymore. In a later step during import the missing binding is detected and subkey_1 is removed because it is not anymore valid. The sig_sub_2.2 will also be removed later because it does not check out for subkey_2 (that is as expected). The fix is to let the de-duplication work only on blocks (ie. within the signatures of a user id or a subkey). This will not detect all duplicates but that does not harm because later steps will detect and remove them. In the above case (with this patch applied) the second phase of key_check_all_keysigs will reorder key signatures and move the duplicate sig_sub_2.2 directly after sig_sub_1.1. This duplicates the signature and for cleanness we should kick the de-duplication process again. This will be done with a followup patch.

* gpg: Fix trustdb updates without lock held.Werner Koch2018-03-261-10/+29
| | | | | | | | | | | | | | | | | | | | | | | * g10/tdbio.c (is_locked): Turn into a counter. (take_write_lock, release_write_lock): Implement recursive locks. -- On trustdb creation we have this call sequence: init_trustdb -> takes lock tdbio_set_dbname create_version_record tdbio_write_record put_record_into_cache -> takes lock put_record_into_cache -> releases lock init_trustdb -> releases lock The second take lock does noting but the first release lock has already released the lock and the second release lock is a thus a NOP. This is likely the cause for the corrupted trustdb as reported in GnuPG-bug-id: 3839 Signed-off-by: Werner Koch <[email protected]>
