* g10/cpr.c (write_status_text_and_buffer): Fix off-by-one
--
Depending on the escaping and line wrapping the computed remaining
buffer length could be wrong. Fixed by always using a break to
terminate the escape detection loop. Might have happened for all
status lines which may wrap.
GnuPG-bug-id: T6027
* g10/keygen.c (keygen_set_std_prefs): Use the right variable when
reading AEAD preference string

GnuPG-bug-id: 6019
Signed-off-by: Jakub Jelen <jjelen@redhat.com>
* g10/export.c (do_export_stream): Merge the key to get the properties
ready.
--
This makes
gpg --export --export-filter 'drop-subkey=usage=~a'
(Export all subkeys but those with the auth usage)
work without using the workaound of adding
--export-options export-clean
* g10/keyedit.c (find_userid_by_namehash, find_userid): New.
(keyedit_quick_revuid): Use find_userid() instead of iterating over the
nodes of the keyblock.
* tests/openpgp/quick-key-manipulation.scm: Add test for revoking a
user ID specified by its hash.
--
This makes it possible to specify the user ID to revoke as UID hash when
calling --quick-revoke-uid.
GnuPG-bug-id: 5936
* 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.
* g10/gpg.c (main): Set LOG_NO_REGISTRY.
* 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.

Note that in the --encrypt and --verify cased other checks may kick in
earlier than this new --require-compliance controlled one.
* common/iobuf.c (filter_flush): Remove "src_len == 0" check.
* g10/compress-bz2.c (do_compress): Exit early if flush not
forced and input length is zero.
* g10/compress.c (do_compress): Likewise.
--
Remove "(src_len == 0)" check in filter_flush which was
introduced to fix compress failure caused by zero length
flush from iobuf_close. However this check broke enarmoring
file with length of zero. Patch instead fixes zero length
flush problem in compress filters.

* g10/cipher-aead.c (do_hash): Add faster path for encrypting directly
from input buffer instead of memcpying then encrypting inplace.
--
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
doing AEAD encryption. AES256.OCB throughput increases from 2.2GB/s
to 4.2GB/s on said system (1.9x faster).

* g10/decrypt-data.c (decrypt_data): Disable estream buffering for

Here estream is filled with iobuf_copy which already uses large buffers

* g10/plaintext.c (handle_plaintext): Disable estream buffering in

Since in binary mode, large buffers are passed from source iobuf to
target estream, extra buffering in estream only causes extra memory
copying and overhead.

As iobuf will have zerocopy operation for read/write, it is better to

* g10/mainproc.c (proc_tree): Call ask_for_detached_datafile
with MD2=NULL.
--
Here, c->mfx.md2 is always NULL, in fact. But, text-wise
(when searching the use of "mfx.md2"), before the change, it used
mfx.md2, which is irrelevant in the handling of PKT_ONEPASS_SIG.
Note that: One-Pass Signature is not available in PGP2.
This fix removes (text-wise) unmatch of the calls of functions
hash_datafile_by_fd hash_datafiles, and ask_for_detached_datafile.

Avoiding extra hash contexts speeds up CFB/MDC decryption quite
a lot. For example, decrypting symmetric-key AES-256 encrypted
4 GiB file from RAM to /dev/null sees ~3.4x speed increase on
AMD Ryzen 5800X:
AES256.CFB encryption: 783 MB/s
AES256.CFB decryption: 386 MB/s (before)
AES256.CFB encryption: 1.3 GB/s (after patch)
Note, AEAD is still significantly faster:
AES256.OCB encryption: 2.2 GB/s
AES256.OCB decryption: 3.0 GB/s
