* g10/keyserver.c (ks_retrieval_filter_arg_s): new.
(keyserver_retrieval_filter): Use new struct and check all
descriptions.
(keyserver_spawn): Pass filter arg suing the new struct.

This is a fix for commit 5e933008.
The old code did only work for a single key. It failed as soon as
several keys are specified ("gpg --refresh-keys" or "gpg --recv-key A
B C").
* g10/main.h (import_filter_t): New.
* g10/import.c (import): Add filter callbacks to param list.
(import_one): Ditto.
(import_secret_one): Ditto.
(import_keys_internal): Ditto.
(import_keys_stream): Ditto.
* g10/keyserver.c (keyserver_retrieval_filter): New.
(keyserver_spawn): Pass filter to import_keys_stream()
--
These changes introduces import functions that apply a constraining
filter to imported keys. These filters can verify the fingerprints of
the keys returned before importing them into the keyring, ensuring that
the keys fetched from the keyserver are in fact those selected by the
user beforehand.

g10/import.c

* g10/misc.c (openpgp_pk_algo_name): New. Replace all calls in g10/
to gcry_pk_algo_name by a call to this function.
(map_pk_openpgp_to_gcry): Map algo PUBKEY_ALGO_ELGAMAL_E to GCRY_PK_ELG.
(openpgp_pk_test_algo): Use PUBKEY_ALGO_ELGAMAL_E instead of
GCRY_PK_ELG_E. Return an error for ECC algos.
(openpgp_pk_test_algo2): Return an error for ECC algos.
* g10/gpg.c (build_list): Avoid printing ECC two times.
* include/cipher.h: Do not use GCRY_PK_* macros for PUBKEY_ALGO_*.

Due to recent changes to adjust for use with Libgcrypt 1.6, "gpg
--version" printed two question marks. This patches fixes that and
also make sure that gpg does advertise any ECC features. The patch in
build_list is not really needed.

* g10/options.h (IMPORT_NO_SECKEY): New.
* g10/keyserver.c (keyserver_spawn, keyserver_import_cert): Set new
flag.
* g10/import.c (import_secret_one): Deny import if flag is set.

By modifying a keyserver or a DNS record to send a secret key, an
attacker could trick a user into signing using a different key and
user id. The trust model should protect against such rogue keys but
we better make sure that secret keys are never received from remote
sources.

* 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).
* g10/misc.c (map_pk_openpgp_to_gcry): New.
* g10/keyserver.c (print_keyrec): Map OpenPGP algorithm ids.

Although we don't have support for ECC, we want to print a proper
algorithm name in keyserver listings. This will only work while using
a ECC enabled Libgcrypt. Problem reported by Kristian Fiskerstrand.
* keyserver.c: Windows Vista doesn't grok X_OK and so fails access()
tests. Previous versions interpreted X_OK as F_OK anyway, so we'll
just use F_OK directly.
to libgcrypt functions, using shared error codes from libgpg-error,
replacing the old functions we used to have in ../util by those in
../jnlib and ../common, renaming the malloc functions and a couple of
types. Note, that not all changes are listed below becuause they are
too similar and done at far too many places. As of today the code
builds using the current libgcrypt from CVS but it is very unlikely
that it actually works.
show_prompt, keyserver_search_prompt, keyserver_spawn): Go to version 1 of
the keyserver protocol. This is a better design, similar to
--with-colons, that allows for keys with multiple user IDs rather than
using multiple keys. It also matches the machine readable pksd format.
Also use a prettier --search-keys listing format that can fill different
size windows (currently set at 24 lines).
* export.c (do_export_stream): Fix noop bug in exporting sensitive
revocation keys.
* pkclist.c (do_edit_ownertrust): Comment out the option for showing trust
paths until it can be implemented.
decryption failed error if a MDC does not verify. Warn if a MDC is not
present (can disable via --no-mdc-warning).
* exec.c (exec_write), g10.c (main), keyserver.c (keyserver_spawn): Use
new DISABLE_KEYSERVER_PATH rather than FIXED_EXEC_PATH.
delete_inv_parts), g10.c (main): New import-option
"repair-hkp-subkey-bug", which repairs as much as possible the HKP
mangling multiple subkeys bug. It is on by default for keyserver
receives, and off by default for regular --import.
* main.h, import.c (import, import_one, delete_inv_parts), hkp.c
(hkp_ask_import), keyserver.c (keyserver_spawn): Use keyserver import
options when doing keyserver receives.
keyserver.c (keyserver_spawn): If the user does not use "exec-path",
completely replace $PATH with GNUPG_LIBEXECDIR before calling the
keyserver helper. If the user does use "exec-path", append
GNUPG_LIBEXECDIR after the specified path.
delete_inv_parts), keyserver.c (parse_keyserver_options): add new
--import-options option. The only current flag is "allow-local-sigs".
* g10.c (main): Don't disable MDC in pgp7 mode.
* options.h, g10.c (main), keyserver.c (parse_keyserver_options): Remove
old keyserver-option include-attributes now that there is an export-option
for the same thing.
g10.c (main): add new --export-options option. Current flags are
"include-non-rfc", "include-local-sigs", "include-attributes", and
"include-sensitive-revkeys".
* options.h, hkp.c (hkp_export), keyserver.c (parse_keyserver_options,
keyserver_spawn): try passing unknown keyserver options to export options,
and if successful, use them when doing a keyserver --send-key.
* build-packet.c (build_sig_subpkt): We do not generate
SIGSUBPKT_PRIV_VERIFY_CACHE anymore.
sensitive revkeys along with the revocation sig itself.
* keyserver.c (parse_keyserver_options): Simpler implementation that can
skip one pass over the options.
designated revoker means "sensitive", not "local". It's exportable under
the right circumstances.
* main.h, options.h, export.c (do_export_stream), g10.c (main), hkp.c
(hkp_export), keyserver.c (keyserver_spawn: Add a flag to skip attribute
packets and their signatures while exporting. This is to accomodate
keyservers (pksd again) that choke on attributes. Use keyserver-option
"include-attributes" to control it. This defaults to ON (i.e. don't
skip).
keyserver_work), hkp.c (hkp_ask_import, hkp_export, hkp_search): Use a
much more strict reading of RFC-2396 for the keyserver URIs. Specifically,
don't try and be smart about checking the value of ":port" so long as it
is all digits, and properly handle opaque data (those scheme specific
parts that do not start with "//").
