* scd/app-openpgp.c (do_change_pin): Fix PIN length check. Add "R"
flag to the reset code prompt.
--
When using the reset code it was not possible to set a PIN of length
6. The "R" flags fixes a funny prompt.
Fixes-commit: efe325ffdf
* scd/app-openpgp.c (do_change_pin): Make sure new PIN length
is longer than MINLEN.

(cherry picked from commit 2376cdff13)
* scd/app-openpgp.c (wipe_and_free_string, wipe_and_free): Enable
functions.
(pin2hash_if_kdf): Change interface. The input PIN is not anymore
changed. Further there are no more assumptions about the length of
the provided buffer.
(verify_a_chv): Adjust for changed pin2hash_if_kdf.
(verify_chv2): Ditto
(verify_chv3): Ditto.
(do_change_pin): Ditto.
(do_sign): Ditto.
--
Note that this a part of the patch
63bda3aad8 which we used in 2.4 to
implement a PIN cache. For easier backporting we need to add this
here.
* agent/command.c (cmd_learn): Add option --reallyforce.
* agent/findkey.c (agent_write_private_key): Implement reallyforce.
Also add arg reallyforce and pass it along the call chain.
* g10/call-agent.c (agent_scd_learn): Pass --reallyforce with a
special force value.
* g10/keygen.c (card_store_key_with_backup): Use that force value.
--
This was a regression in 2.2.42. We took the easy path to fix it by
getting the behaviour back to what we did prior to 2.2.42. With GnuPG
2.4.4 we use an entire different and safer approach by introducing an
ephemeral private key store.
GnuPG-bug-id: 6944
* g10/sign.c (do_sign): Skip compliance check for revocation certs.
--
It just does not make sense to inhibit the creation of revocations
depending on the compliance mode. We do this only for key revocation
but not for another kind of revocation because the rationale for uid
or subkey revocation is more complicated to explain.
* common/homedir.c (copy_dir_with_fixup) [W32]: Fold double
backslashes.
--
This is in general no problem but when we hash or compare the directory
to test whether tit is the standard home directory, we may use a
different socket file and thus a second instance of a daemon.
GnuPG-bug-id: 6833
* 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.
See-commit: c03ba92576
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.
GnuPG-bug-id: 6253
Backported-from-master: 8dfef5197a
* 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.
