* g10/ecdh.c (pk_ecdh_decrypt): Allocate just the right size of memory
for the session key, simplifying the decrypt process.

This avoids extra build dependencies. Note that bzip2 is not
necessary statically linked but an existing bzip2 SO might be used.
We would need to fix the bzip2 SO building and also provide a gnupg
configure option to build statically against bzip2.
* agent/agent.h (struct ephemeral_private_key_s): New.
(struct server_control_s): Add ephemeral_mode and ephemeral_keys.
(GENKEY_FLAG_NO_PROTECTION, GENKEY_FLAG_PRESET): New.
* agent/genkey.c (clear_ephemeral_keys): New.
(store_key): Add arg ctrl and implement ephemeral_mode. Change all
callers.
(agent_genkey): Replace args no_protection and preset by a generic new
flags arg.
* agent/findkey.c (wipe_and_fclose): New.
(agent_write_private_key): Add arg ctrl and implement ephemeral_mode.
Change all callers.
(agent_update_private_key): Ditto
(read_key_file): Ditto.
(agent_key_available): Ditto.
* agent/command-ssh.c (card_key_available): Do not update display s/n
in ephemeral mode. This is however enver triggred.
* agent/gpg-agent.c (agent_deinit_default_ctrl): Cleanup ephemeral
keys.
* agent/command.c (cmd_genkey): Use the new flags instead of separate
vars.
(cmd_readkey): Create a shadow key only in non-ephemeral_mode.
(cmd_getinfo): Add sub-command "ephemeral".
(option_handler): Add option "ephemeral".
--
The idea here that a session can be switched in an ephemeral mode
which does not store or read keys from disk but keeps them local to
the session.
GnuPG-bug-id: 6944
* g10/keygen.c (struct common_gen_cb_parm_s): New.
(common_gen): Add args common_gen_cb and common_gen_cb_parm. Adjust
all callers.
(do_generate_keypair): Clarify the code by using a better var name.
--
We may eventually also replace the long arg list with that object.
The immediate reason for this change is the followup commit.
* g10/keygen.c (curve_is_448): New.
(do_create_from_keygrip): Pass arg keygen_flags byref so that it can
be updated. Set v5 flag for X448.
(gen_ecc): Ditto.
(do_create): Change keygen_flags as above. For robustness change
checking for Ed448.
(do_generate_keypair): Change keygen_flags as above
(generate_subkeypair): Ditto.
(gen_card_key): Ditto. Support v5 keys.

* g10/keygen.c (proc_parameter_file): Don't include RENC in the
default usage.

Testplan:
$ gpg --gen-key --batch <<EOF

and check that the R flag does not show up in the usage.

Jakub provided the translation in October but at this time it did
cleanly apply anymore due to string changes. Thus only parts of his
changes are here. -wk
* sm/minip12.c (struct p12_parse_ctx_s): Add privatekey2.
(parse_shrouded_key_bag): Handle a second private key.
(p12_parse_free_kparms): New.
* sm/import.c (parse_p12): Factor some code out to ...
(p12_to_skey): this.
(parse_p12): Use p12_parse_free_kparms.
--
Take care: We allow parsing of a second private key but we are not yet
able to import the second private key.
The whole things is required to at least import the certificates of
current pkcs#12 files as created by the German Elster tax system. No
test data, sorry.
* g10/keygen.c (parse_revocation_key): Actually allow for v4
fingerprints.
--
Note that the use of the parameter file is deprecated.
GnuPG-bug-id: 6923
* 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.
* scd/app-p15.c (do_sign): Add code for Starcos 3.2 and the CVISION
product.
--
The code for the Starcos cards has been implemented according to the
3.52 manual However, this does not work with my test cards. Protocol
analysis shows that decryption can be used for the cryptovision
product. Thus we do it the same for now.
* g13/g13.c (oNoMount): New.
(opts): Add --no-mount.
(main): Implement this.
* g13/g13-common.h (opt): Add field no_mount.
* common/status.h (STATUS_PLAINDEV): New.
* g13/sh-cmd.c (has_option): Uncomment.
(cmd_mount): Add option --no-mount and pass down.
* g13/sh-dmcrypt.c (sh_dmcrypt_mount_container): Add arg nomount and
emit PLAINDEV status line.
(sh_dmcrypt_umount_container): Rund findmnt before umount.
--
This option can be used to decrypt a device but not to mount it. For
example to run fsck first. A command or option to run fsck before a
mount will eventually be added.
The use of findmnt is needed so that we can easily remove a device
which has not been mounted.
* g10/parse-packet.c (parse_key): Detect the SKI algo 253.
--
As long as we have not yet implemented this we should at least be
able to detect this case.
* scd/app-p15.c (CARD_PRODUCT_CVISION): New.
(IS_STARCOS_3): New.
(read_p15_info): Detect this product.
(prepare_verify_pin): Add special handling for this product.
(do_decipher): Use dedicated MSE for Starcos 3 cards.
--
To check the verification run
gpg-card verify User_PIN
For our test cards the "Benutzer-PIN" must be given. For decryption
tests gpgsm can be used; --always-trust helps to avoid chain issues.
* 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-common.h (CARDTYPE_SCE7): New.
* scd/app.c (strcardtype): Support it.
(atr_to_cardtype): New.
(app_new_register): Try to get the cardtype from atr_to_cardtype.
* scd/app-piv.c (app_select_piv): Tweak for SCE7. Add general method
to construct a S/N from the Card UUID.
--
The test cards I have are rsa2048 with X.509 certificates. I don't
have the entire chain but loading the certificates work. For testing
I created an OpenPGP key from the keys and tested signing and
decryption.
GnuPG-bug-id: 6919
* g10/call-agent.c (agent_probe_secret_key): Do not return an error
but 0.
* g10/getkey.c (finish_lookup): Improve the selection of secret keys.
