* scd/command.c (cmd_readkey): avoid double-free of cert
--
When ksba_cert_new() fails, cert will be double-freed.
Debian-Bug-Id: 773471
Original patch changed by wk to do the free only at leave.
* scd/app-common.h (APP_DECIPHER_INFO_NOPAD): New.
* scd/app-openpgp.c (do_decipher): Add arg R_INFO.
* scd/app-nks.c (do_decipher): Add arg R_INFO as a dummy.
* scd/app.c (app_decipher): Add arg R_INFO.
* scd/command.c (cmd_pkdecrypt): Print status line "PADDING".
* agent/call-scd.c (padding_info_cb): New.
(agent_card_pkdecrypt): Add arg R_PADDING.
* agent/divert-scd.c (divert_pkdecrypt): Ditto.
* agent/pkdecrypt.c (agent_pkdecrypt): Ditto.
* agent/command.c (cmd_pkdecrypt): Print status line "PADDING".
* g10/call-agent.c (padding_info_cb): New.
(agent_pkdecrypt): Add arg R_PADDING.
* g10/pubkey-enc.c (get_it): Use padding info.
--
Decryption using a card never worked in gpg 2.1 because the
information whether the pkcs#1 padding needs to be removed was not
available. Gpg < 2.1 too this info from the secret sub key but that
has gone in 2.1.

* scd/command.c (update_reader_status_file): Add condition
vr->status == 0.
--
To reproduce the bug: (1) insert card,
(2) run "gpg2 --card-status",
(3) remove card, (4) invoke "gpg2 --card-edit",
(5) invoke some command like "verify"
The last step fails (but with no error message to user).
* scd/iso7816.h (struct pininfo_s): Rename from iso7816_pininfo_s.
Change meaning of MODE.

* scd/scdaemon.c, scd/command.c: Likewise.

* scd/app.c: Include "apdu.h" after "iso7816.h".
* scd/iso7816.c (iso7816_check_keypad, iso7816_verify_kp)

* scd/apdu.c (struct reader_table_s): Change API of CHECK_KEYPAD,
KEYPAD_VERIFY, KEYPAD_MODIFY to have arg of PININFO_T.
(check_pcsc_keypad, check_ccid_keypad): Likewise.
(apdu_check_keypad, apdu_keypad_verify, apdu_keypad_modify): Likewise.
(pcsc_keypad_verify, pcsc_keypad_modify, ct_send_apdu)
(pcsc_send_apdu_direct, pcsc_send_apdu_wrapped, pcsc_send_apdu)

(send_le): Follow the change of API.
* scd/apdu.h (apdu_check_keypad, apdu_keypad_verify)
(apdu_keypad_modify): Change the API.
* scd/app-dinsig.c, scd/app-nks.c, scd/app-openpgp.c: Follow the
change.

(open_card, cmd_serialno, scd_command_handler): Remove reader_disabled
support.
* scd/sc-copykeys.c (main): Follow the change of R_NO_SERVICE.
--
Daemon should handle all possible cases. Even if such a difficult
case like reader_disabled, it should not exit.
* scd/command.c (update_reader_status_file): Don't call
get_current_reader.
--
This fix has a impact that the insertion of a card reader will not be
detected upon the insertion, but will be deferred until user tries to
access his card.
* scd/command.c (MAXLEN_SETDATA): New.
(cmd_setdata): Add option --append.
* agent/call-scd.c (agent_card_pkdecrypt): Use new option for long
data.
* scd/app-openpgp.c (struct app_local_s): Add field manufacturer.
(app_select_openpgp): Store manufacturer.
(do_decipher): Print a note for broken cards.
--
Please note that I was not able to run a full test because I only have
broken cards (S/N < 346) available.
The asymmetric quotes used by GNU in the past (`...') don't render
nicely on modern systems. We now use two \x27 characters ('...').
The proper solution would be to use the correct Unicode symmetric
quotes here. However this has the disadvantage that the system
requires Unicode support. We don't want that today. If Unicode is
available a generated po file can be used to output proper quotes. A
simple sed script like the one used for en@quote is sufficient to
change them.
The changes have been done by applying
sed -i "s/\`\([^'\`]*\)'/'\1'/g"
to most files and fixing obvious problems by hand. The msgid strings in
the po files were fixed with a similar command.
* scd/command.c (update_card_removed): Do no act on an invalid VRDR.
(do_reset): Ignore apdu_reset error codes for no and inactive card.
Close the reader before setting the slot to -1.
(update_reader_status_file): Notify the application before closing the
reader.
--
With this change the scd now works as it did in the past. In
particular there is no more endless loop trying to open the reader by
the update_reader_status_file ticker function. That bug basically
blocked all card operations until the scdaemon was killed.
The vreader table makes the code more clear by explicitly talking
about APDU slots and reader indices. It also accommodates for future
extensions.
* scd/scdaemon.h (server_control_s): Remove READER_SLOT.
* scd/scdaemon.c (scd_init_default_ctrl): Do not init READER_SLOT.
* scd/app.c (check_application_conflict): Add arg SLOT.
* scd/command.c (slot_status_s): Rename to vreader_s.
(server_local_s): Add field VREADER_IDX as replacement for
the READER_SLOT in server_control_s. Change all users.
(slot_table): Rename to vreader_table. Change all users.
(vreader_slot): New.
(do_reset, cmd_apdu): Map vreader to apdu slot.
(get_reader_slot): Rename to get_current_reader. Return -1 on error.
(open_card): Map vreader toapdu slot. Pass slot to
check_application_conflict.
(scd_command_handler): Init VREADER_IDX.
(update_reader_status_file): Reset SLOT field on error.
* scd/apdu.c (apdu_connect): Return status codes for no card available
and inactive card.
* scd/command.c (TEST_CARD_REMOVAL): Also test for GPG_ERR_CARD_RESET.
(open_card): Map apdu_connect status to GPG_ERR_CARD_RESET.
This patch implementes a chunk mode to pass the key parameters from
scdaemon to gpg. This allows to pass arbitrary long key paremeters;
it is used for keys larger than 3072 bit.
Note: the card key generation in gpg is currently broken. The keys
are generated but it is not possible to create the self-signature
because at that time the gpg-agent does not yet know about the new
keys and thus can't divert the sign request to the card. We either
need to run the learn command right after calling agent_scd_genkey or
implement a way to sign using the currently inserted card. Another
option would be to get rid of agent_scd_genkey and implement the
feature directly in agent_genkey.
We better do this once and for all instead of cluttering all future
commits with diffs of trailing white spaces. In the majority of cases
blank or single lines are affected and thus this change won't disturb
a git blame too much. For future commits the pre-commit scripts
checks that this won't happen again.
From Grant Olsons's mail to gnupg-devel@:
This is three-quarters NIIBE and one-quarter me, but I though it would
be easier to have a single complete patch that applies to
STABLE-BRANCH-2-0 than two patches floating around.
This is basically NIIBE Yatuka's patch here:
http://lists.gnupg.org/pipermail/gnupg-devel/2010-November/025828.html
Plus another check that closes down the reader explicitly if we get a
SW_HOST_NO_READER error, so that an unplugged reader doesn't hold onto
the first slot, preventing us from getting to the active plugged reader.
