* g10/pkclist.c (find_and_check_key): Call get_validity on a specific
keyblock.
--
When we have multiple keyrings, get_validity after
get_best_pubkey_byname should access same keyring. Or else, the
situation of an expired key in keyring A but valid key in keyring B
causes SEGV.
Thanks to Guido Günther for the use case and the log.

* g10/keydb.c (keydb_handle): New field 'keep_lock'.

(keydb_lock): New function.
(unlock_all): Skip if KEEP_LOCK is set.
* g10/getkey.c (get_keyblock_byfprint_fast): Call keep_lock if
requested.
--
That change is straightforward. It helps to avoid the race condition
that another gpg process inserts a key while the first process is
between the search and the insert.
A similar change is due for gpgsm.
Note that the key edit operations may still suffer from a race.

(get_keyblock_byfprint_fast): .. new function.
* g10/import.c (revocation_present): s/int rc/gpg_error_t err/.

handle. Remove the now surplus keyblock fetch in the merge branch.

* g10/import.c (import_keys_internal): Return gpg_error_t instead of
int. Change var names.
(import_keys_es_stream): Ditto.
(import_one): Ditto. Use a single keydb_new and simplify the use of
of keydb_release.
--
Note that this opens a keydb handle before we call
get_pubkey_byfprint_fast which internally uses another key db handle.
A further patch will cleanup this double use. Note that we also
disable the keydb caching for the insert case.
The s/int/gpg_error_t/ has been done while checking the call chains of
the import functions and making sure that gpg_err_code is always used.

This new option can be used to detect ROCA affected keys. To scan an

gpg -k --with-key-screening --with-colons | gawk -F: \
'$1~/pub|sub|sec|ssb|crt/ && $18~/\<6001\>/ {found=1;next};
$1=="fpr" && found {print $10}; {found=0}'
The same works for gpgsm. Note that we need gawk due to the "\<" in
the r.e.

This problem is fallout from

which fixes
GnuPG-bug-id: 1206
The same could happen with other options taking keyids but we won't
change that because a trailing '#' does not indicate a comment. So
this is really only a workaround and eventually we will
deprecate --trusted-key anyway or require a fingerprint as a value.

The compliance checker needs to be initialize so that it won't let

Because there is no option to change the compliance mode in gpgv we
will always be in the default (CO_GNUPG) mode. It also does not make
much sense to have it here because gpgv expects a "curated" keyring.

It's 2017, and pretty much everyone has AES-256 available. Symmetric
crypto is also rarely the bottleneck (asymmetric crypto is much more
expensive). AES-256 provides some level of protection against
large-scale decryption efforts, and longer key lengths provide a hedge
against unforseen cryptanalysis.
