* g10/ecdh.c (derive_kek): Use GCRY_KDF_ONESTEP_KDF.
--
This change is not yet enabled. We will be able to use the code when
we update NEED_LIBGCRYPT_VERSION to 1.11.0. Before the update, gpg
compiled with libgcrypt 1.11.0 can't work with older libgcrypt
runtime.

Before 8402815d, original code was with iobuf_open_fd_or_name, which
used gnupg_fd_t for the file descriptor (FD2INT was relevant at that
time). After the change, because it's not gnupg_fd_t but int, use of
FD2INT is irrelevant.

I have seen to many of these diagnostics and in particular the first

sense to show them in standard verbose mode.
The ISO timestamp is much easier to read than than the localized

--
The original check was too strong because it is in fact compliant to
encrypt with a symmetric key and and public key. Thus decryption
should issue a compliance status.
In addition we now check that the cipher algorithms used to
symmetrically encrypt the session key are all compliant. This is
similar to our check for all public key encrypted session key packets.

* g10/mainproc.c (proc_symkey_enc): Issue new error code.
(proc_encrypted): Ditto.
--
This allows GPGME to return a better error message than "bad session
key" to the user. Technically we could get run into these errors also
in other cases but this more unlikley. For the command line use we
don't do anything to not change the expected output of the command
line interface.
GnuPG-bug-id: 5943
* g10/keyedit.c (menu_adduid): Move linefeed character to the format
string.

This fixes a literal '\n' in the error message and a missing line feed
after the error message.

* sm/gpgsm.c (main): Ditto.
* tools/gpg-connect-agent.c (main): Ditto.
* tools/gpgconf.c (main): Ditto.
(show_other_registry_entries): Print "DefaultLogFile".
--
The intention of this mostly forgotten registry entry was to allow for
easy debugging of the tools. However, with the global config file
common.conf things are anyway better. We disable the use for the
commonly used tools so that it does not look like calling gpg on the
command line seems to block with no output if the log
server (e.g. tcp://1.2.3.4:11111) is not reachable.
* g10/keygen.c (ask_user_id): Allow for the name to start with a
digit. Allow names shorter than 5.
--
The reason for this change is that we don't enforce these constraints
in the --quick-gen-key interface. I added the constraints right in the
beginning of gnupg to make sure that we have a uniform style for
user-ids. However, this is all problematic with non-Latin names
and we prefer to use mail addresses anyway.
* g10/gpg.c (main): Remove note about rfc4880bis.
* g10/keygen.c (keygen_set_std_prefs): Use only OCB in the AEAD
preference list.
--
It is more than unlikely that EAX will ever be used in practice and
thus we remove it from the preference list.
* g10/misc.c (openpgp_cipher_algo_mode_name): New.
* g10/decrypt-data.c (decrypt_data): Use function here.
--
Note that openpgp_cipher_algo_mode_name is different from the version
2.2 becuase we append ".CFB" here.
Without this change we would see
gpg: cipher algorithm 'AES256' may not be used in
--compliance=de-vs mode
This is confusing because AES256 is compliant. Now we see
gpg: cipher algorithm 'AES256.OCB' may not be used in
--compliance=de-vs mode
which gives a hint on the problem.
* g10/decrypt-data.c (decrypt_data): Add arg compliance_error. Adjust
all callers. Fail on compliance error only in --require-compliance
mode. Make sure to return an error if the buffer is missing; actually
that should be an assert.
* g10/mainproc.c (proc_encrypted): Delay printing of the compliance
mode status. Consult the compliance error now returned by
decrypt_data.
--
The actual case here is that we fail hard if a message has been AEAD
encrypted with one AEAD capable key and also with one passphrase. In
general the preference system takes care of not using AEAD if one
recipient's key does not support it. However, if the sender uses her
own AEAD-capable key _and_ a passphrase the message will be AEAD
encrypted. This change allows to decrypt that anyway along with a
warning message.
Note that this does currently not work in 2.3 due to a non-compliant
libgcrypt. We will however, backport this to 2.2.
* g10/sign.c (sign_symencrypt_file): Insert correct version and AEAD
information into symkey packet.

Remove "(src_len == 0)" check in filter_flush which was

flush from iobuf_close. However this check broke enarmoring

flush problem in compress filters.

When encrypting with AES256.OCB on AMD Ryzen 5800X, memcpy shows as
taking largest portion of computation time. Patch adds fast path for
AEAD encryption which largely eliminates need for memcpying when

to 4.2GB/s on said system (1.9x faster).
