* scd/app-openpgp.c (ecc_writekey): Remove the useless check and print
a diagnostic if the default params are used.
--
Note that here in 2.2 we use different default ECDH parameters than in
2.4 (AES192 instead of AES256 for 384 bit curves).
GnuPG-bug-id: 6378
* agent/findkey.c (read_key_file): Add optional arg r_orig_key_value
to return the old Key value. Change all callers.
(agent_write_private_key): Detect whether the Key entry was really
changed.
--
GnuPG-bug-id: 6829
* common/name-value.c (struct name_value_container): Add flag
"modified".
(nvc_modified): New.
(nvc_new): Set flag.
(_nvc_add): Set flag.
(nvc_delete): Set flag.
(nve_set): Add arg PK. Change the caller. Check whether to change at
all.
* 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
* g10/call-agent.c (agent_get_passphrase): Call
assuan_begin_confidential and assuan_end_confidential.
* sm/call-agent.c (gpgsm_agent_ask_passphrase): Ditto.
--
GnuPG-bug-id: 6654
The drawback of this solution is that we don't see any IPC lines from
the assuan_transact. Everything else would require larger changes to
libassuan.
* sm/encrypt.c (gpgsm_encrypt): Unify use of RC and ERR.
* sm/sign.c (gpgsm_sign): ditto.
--
Initially we didn't used the gpg_error_t thingy and while migrating
we sometimes used RC and ERR for tracking the error. This is pretty
error prone and thus we better remove it (after 20 years).
* 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.
--
Backported from 2.4 - here the gpg part.

This is related to
GnuPG-bug-id: 6378
* agent/command.c (KEYTOCARD_TIMESTAMP_FORMAT): Remove and use format
string direct.
(cmd_keytocard): Change timestamp to an u64 and use the new u64 parser
functions. Use split_fields. Add ecdh parameter stuff. Take the
default timestamp from the keyfile.
* agent/findkey.c (agent_key_from_file): Add arg timestamp and set it.
Adjust all callers.
--
This is backport from 2.4 but only the agent part. We consider it
more relibale if we also pass the ECDH parameters along in 2.2.
Adding the timestamp stuff should not harm either. Because we now
have the u64 time string parser, we use them here.

This patch is somewhat related to:
GnuPG-bug-id: 6378, 5538
* common/mischelp.c (timegm): Move to ...
* common/gettime.c (timegm): here. On Windows use timegm_u32.
(timegm_u32): New.
(isotime2epoch): Factor code out to ...
(isotime_make_tm): new helper.
(isotime2epoch_u64): New.
(_win32_timegm): Remove duplicated code.
(parse_timestamp): Use of timegm.
(scan_isodatestr): Fallback to isotime2epoch_u64.

This mainly helps on 32 bit Windows. For Unix we assume everyone is
using 64 bit or shall wait until the libc hackers finally provide a
time64_t.
GnuPG-bug-id: 6736
* sm/minip12.c (struct tlv_ctx_s): Add origbuffer and origbufsize.
Remove pop_count. Rename offset to length.
(dump_tag_info, _dump_tag_info): Rewrite.
(dump_tlv_ctx, _dump_tlv_ctx): Rewrite.
(tlv_new): Init origbuffer.
(_tlv_peek): Add arg ti.
(tlv_peek): New.
(tlv_peek_null): New.
(_tlv_push): Rewrite.
(_tlv_pop): Rewrite.
(tlv_next): New macro. Move old code to ...
(_tlv_next): this. Add arg lno. Pop remaining end tags.
(tlv_popped): Remove.
(tlv_expect_object): Handle ndef.
(tlv_expect_octet_string): Ditto.
(parse_bag_encrypted_data): Use nesting level to control the inner
loop.
(parse_shrouded_key_bag): Likewise.
(parse_bag_data): Handle surplus octet strings.
(p12_parse): Ditto.
* sm/minip12.c (decrypt_block): Strip the padding.
(tlv_expect_top_sequence): Remove. Replace callers by
tlv_expect_sequence.
* tests/samplekeys/t6752-ov-user-ff.p12: New sample key.
* tests/samplekeys/Description-p12: Add its description
--
This patch improves the BER parser by simplifying it. Now tlv_next
pops off and thus closes all containers regardless on whether they are
length bounded or ndef. tlv_set_pending is now always used to undo
the effect of a tlv_next in a loop condition which was terminated by a
nesting level change.
Instead of using the length as seen in the decrypted container we now
remove the padding and let the BER parser do its work. This might
have a negative effect on pkcs#12 objects which are not correctly
padded but we don't have any example of such broken objects.
GnuPG-bug-id: 6752
* sm/t-minip12.c (run_one_test): Don't hash if we have no parameters
at all.
--
This fix handles the case that an empty result array is returned by
minip12.c
* sm/import.c (parse_p12): Support ECC import.
--
Although I extended the parser and its test the actual import
missed the required code.

* m4/autobuild.m4 (AB_INIT): Add username.
--
The old autobuild diagnostics show up in build logs. What they are
missing is an information on the user who triggered a build. EMAIL is
a common thing to denote the actual user using a service account.
* g10/keygen.c (parse_expire_string_with_ct): Use new function
scan_secondsstr.
(parse_creation_string): Ditto.
--
Noet that we cap the seconds at the year 2106.
GnuPG-bug-id: 6736
* scd/app-openpgp.c (check_keyidstr): Ignore the card version and also
compare case insensitive.
(do_learn_status): Add mssing error handling.
--
This is required because we changed what we emit as serialno of
OpenPGP cards but existing keys still use the old form of the serial
number (i.e. with a firmware version). This is so that existing stub
keys of gpg-agent will continue to work.
GnuPG-bug-id: 5100
* scd/app-openpgp.c (do_readkey): Allow the keygrip for the keyid.
Use case insensitive match forthe keyid.
(do_readcert): Allow the keygrip for the keyid.
--
This patch is only to sync ths up with master.
* scd/app-openpgp.c (retrieve_fprtime_from_card): New.
(send_keypair_info): Add more to KEYPAIRINFO.
--
This is mainly needed to sync this version with master.
* scd/app-openpgp.c (wipe_and_free): New.
(wipe_and_free_string): New.
(get_disp_serialno): Remove. Replace callers by function
app_get_dispserialno.
(get_usage_string): New.
(send_keypair_info): Use new function.
--
The new function has the same behaviour. The wipe functions are
not yet used.
* cd/app-openpgp.c (data_objects): Add 0x00FA.
(do_getattr): Add KEY-ATTR-INFO.
--
See the section 4.4.3.11 Algorithm Information in the OpenPGP card
functional specification version 3.4.1.

(parse_algorithm_attribute): Set ecc.algo field from card.
Add checking for Ed25519 for ECC_FLAG_DJB_TWEAK flag.
--
There used to be a possible support of Ed25519 with ECDSA, (instead of
EdDSA). To distinguish key for Ed25519 for EdDSA, we use the
flag: (flags eddsa). Ed448 has no support for ECDSA and defaults to
EdDSA even if no such flag.

Also included the relevant part from
commit 0240345728a84d8f235ce05889e83963e52742eb

support the UIF.
* scd/app-openpgp.c (struct app_local_s): Add new flag.
(get_cached_data): Force chace use if flag is set.
(app_select_openpgp): Avoid reading DO 6E multiple times.
--
The do not cache property of 6E was introduced so that we can change
for example key attributes without getting into with the cache.
However, for initial reading the cache makes a lot of sense and thus we
now use this hack to only temporary cache. A better strategy would be
to clear the cache when we change card data but that is more error
prone.
