* common/utf8conv.c [HAVE_ANDROID_SYSTEM]: Do not include iconv.h.
(iconv_open, iconv_close, load_libiconv) [HAVE_ANDROID_SYSTEM]: New
dummy functions.
(set_native_charset) [HAVE_ANDROID_SYSTEM]: Force use of "utf-8".

(struct ssh_key_type_spec): Add fields CURVE_NAME and HASH_ALGO.
(ssh_key_types): Add types ecdsa-sha2-nistp{256,384,521}.
(ssh_signature_encoder_t): Add arg spec and adjust all callers.
(ssh_signature_encoder_ecdsa): New.
(sexp_key_construct, sexp_key_extract, ssh_receive_key)
(ssh_convert_key_to_blob): Support ecdsa.
(ssh_identifier_from_curve_name): New.
(ssh_send_key_public): Retrieve and pass the curve_name.
(key_secret_to_public): Ditto.
(data_sign): Add arg SPEC and change callers to pass it.
(ssh_handler_sign_request): Get the hash algo from SPEC.
* common/ssh-utils.c (get_fingerprint): Support ecdsa.
* agent/protect.c (protect_info): Add flag ECC_HACK.
(agent_protect): Allow the use of the "curve" parameter.
* agent/t-protect.c (test_agent_protect): Add a test case for ecdsa.
* agent/command-ssh.c (ssh_key_grip): Print a better error code.
--
The 3 standard curves are now supported in gpg-agent's ssh-agent
protocol implementation. I tested this with all 3 curves and keys
generated by OpenSSH 5.9p1.
Using existing non-ssh generated keys will likely fail for now. To fix
this, the code should first undergo some more cleanup; then the fixes
are pretty straightforward. And yes, the data structures are way too
complicated.
* agent/command-ssh.c: Remove dirent.h.
(control_file_s): Add struct item.
(rewind_control_file): New.
(search_control_file): Factor code out to ...
(read_control_file_item): New.
(ssh_handler_request_identities): Change to iterate over entries in
sshcontrol.
--
Formerly we scanned the private key directory for matches of entries
in sshcontrol. This patch changes it to scan the sshcontrol file and
thus considers only keys configured there. The rationale for this is
that it is common to have only a few ssh keys but many private keys.
Even if that assumption does not hold true, the scanning of the
sshcontrol file is faster than reading the directory and only then
scanning the ssh control for each directory entry.
* agent/command-ssh.c (SSH_CONTROL_FILE_NAME): New macro to replace
the direct use of the string.
(struct control_file_s, control_file_t): New.
(open_control_file, close_control_file): New. Use them instead of
using fopen/fclose directly.
* agent/gpg-agent.c (main): Pass new envar gnupg_SSH_AUTH_SOCK_by to
an invoked process.
--
This environment variable is useful for debugging if
--use-standard-socket is used (which is the default since 2.1).
Commonly you should have this in your init script (e.g. ~/.bashrc):
unset GPG_AGENT_INFO
unset SSH_AGENT_PID
SSH_AUTH_SOCK="${HOME}/.gnupg/S.gpg-agent.ssh"
export SSH_AUTH_SOCK
The problem is that gpg-agent won't be able to override the
SSH_AUTH_SOCK envvar if gpg-agent has been invoked as
gpg-agent --enable-ssh-support --daemon /bin/bash
To fix this you should instead use this code in the init script:
unset GPG_AGENT_INFO
unset SSH_AGENT_PID
if [ ${gnupg_SSH_AUTH_SOCK_by:-0} -ne $$ ]; then
export SSH_AUTH_SOCK="${HOME}/.gnupg/S.gpg-agent.ssh"
fi
This will work in all cases and thus allows to start gpg-agent for
testing purposes with a different homedir and use this gpg-agent as an
ssh-agent. Example:
GNUPGHOME=$(pwd) gpg-agent --enable-ssh-support --daemon /bin/bash
gnupg_SSH_AUTH_SOCK_by is set to the PID of the exec-ed process and
thus will work safely if called recursively.
* scd/apdu.c (pcsc_no_service): Remove.
(open_pcsc_reader_direct, open_pcsc_reader_wrapped): Remove
pcsc_no_service support.
(apdu_open_reader): Remove R_NO_SERVICE.
* scd/apdu.h (apdu_open_reader): Remove R_NO_SERVICE.
* scd/command.c (reader_disabled): Remove.
(get_current_reader): Follow the change of R_NO_SERVICE.
(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.
* keyserver.c (print_keyrec): Honor --keyid-format when getting back
full fingerprints from the keyserver (the comment in the code was
correct, the code was not).
* configure.ac (HAVE_BROKEN_TTYNAME): New ac_define set for Android
systems.
* common/util.h (gnupg_ttyname): New macro. Change all callers of
ttyname to use this macro instead.
(ttyname) [W32]: Rename to _gnupg_ttyname and use also if
HAVE_BROKEN_TTYNAME is defined.
* common/simple-pwquery.c (agent_send_all_options): Keep on using
ttyname unless HAVE_BROKEN_TTYNAME is set. This is because this file
may be used standalone.
* 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.
* findkey.c (agent_public_key_from_file): Fix use of
gcry_sexp_build_array.
--
A test case leading to a segv in Libgcrypt is
gpg-connect-agent \
"READKEY 9277C5875C8AFFCB727661C18BE4E0A0DEED9260" /bye
The keygrip was created by "monkeysphere s", which has a comment.
gcry_sexp_build_array expects pointers to the arguments which is quite
surprising. Probably ARG_NEXT was accidentally implemented wrongly.
Anyway, we can't do anything about it and thus need to fix the check
the users of this function.

* configure.ac (HAVE_ANDROID_SYSTEM, RUN_TESTS): New.
(AH_BOTTOM) [__ANDROID__]: Do not re-define ttyname.
* Makefile.am: Depend tests on new RUN_TESTS conditional.
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.
* configure.ac: Add all the require m4 magic.
--
This also removes the hack to allow custom version numbers which are
not considered a development version. A custom version number can be
done anyway by simply setting the version to it and tag the release
with it.
* g10/keygen.c (keygen_set_std_prefs): Include IDEA only in PGP2
compatibility mode.
* g10/misc.c (idea_cipher_warn): Remove. Also remove all callers.
* common/status.h (STATUS_RSA_OR_IDEA): Remove. Do not emit this
status anymore.
--
To keep the number of actually used algorithms low, we want to support
IDEA only in a basically read-only way (unless --pgp2 is used during
key generation). It does not make sense to suggest the use of this
old 64 bit blocksize algorithm. However, there is old data available
where it might be helpful to have IDEA available.
* common/Makefile.am (CLEANFILES): Rename to MAINTAINERCLEANFILES.
--
In general this is not required because automake does this for files
in BUILT_SOURCES anyway. However, having them in CLEANFILES is wrong.
This is bug#1398.
* agent/trustlist.c (clear_trusttable): New.
(agent_reload_trustlist): Use new function.
(read_trustfiles): Require to be called with lock held.
(agent_istrusted): Factor all code out to ...
(istrusted_internal): new. Add ALREADY_LOCKED arg. Make sure the
table islocked. Do not print TRUSTLISTFLAG stati if called internally.
(agent_marktrusted): Replace calls to agent_reload_trustlist by
explicit code.
--
In contrast to pth, npth does not use recursive mutexes by default.
However, the code in trustlist.c assumed recursive locks and thus we
had to rework it.
When the KILLSCD command had been sent a race condition would occur
causing PID -1 getting killed, which on Linux seems to terminate all
applications for the current user.
