* common/http.c (http_session_t): Add field "refcount".
(_my_socket_new, _my_socket_ref, _my_socket_unref): Add debug code.
(send_request, my_npth_read, my_npth_write): Use SOCK object for the
transport ptr.
(http_session_release): Factor all code out to ...
(session_unref): here. Deref SOCK.
(http_session_new): Init refcount and transport ptr.
(http_session_ref): New. Ref and unref all assignments.
--
Having the reference counted session objects makes it easier for the
application to pass around only an estream. Without that the
application would need to implement an es_onclose machinery for the
session object.
* configure.ac (HAVE_NPTH): New ac_define.
* common/estream.c: Use USE_NPTH instead of HAVE_NPTH.
* common/http.c: Ditto. Replace remaining calls to pth by npth calls.
(connect_server): Remove useless _().
* common/exechelp-posix.c, common/exechelp-w32.c
* common/exechelp-w32ce.c: Use HAVE_PTH to include npth.h.
* common/init.c (_init_common_subsystems): Remove call to pth_init.
* common/sysutils.c (gnupg_sleep): Use npth_sleep.
* scd/ccid-driver.c (my_sleep): Ditto.
--
USE_NPTH is used in case were we may build with and without nPth. The
missing definition HAVE_NPTH didn't allowed us to build outher sources
with nPTh support.
* src/estream.c (estream_internal): Add field SAMETHREAD.
(init_stream_lock, lock_stream, trylock_stream, unlock_stream): Use it.
(parse_mode): Add arg SAMETHREAD and parse that keyword.
(es_initialize): Rename to ...
(init_stream_obj): this. Add arg SAMETHREAD.
(es_create): Add arg SAMETHREAD. Call init_stream_lock after
init_stream_obj.
(doreadline): Call es_create with samethread flag.
(es_fopen, es_mopen, es_fopenmem, es_fopencookie, do_fdopen)
(do_fpopen, do_w32open): Implement "samethread" keyword.
(es_freopen): Take samthread flag from old stream.
(es_tmpfile): Call es)_create w/o samethread.
--
Note: Unfortunately es_tmpfile has no mode arg so that we can't use
samethread.
* agent/cvt-openpgp.c (get_keygrip, convert_secret_key)
(convert_transfer_key): Follow newer (>= 1.6) libgcrypt API, which
does not distinguish the detail.
(do_unprotect, convert_from_openpgp_main): Don't call
map_pk_openpgp_to_gcry, as it's the value of libgcrypt API already and
not the value defined by OpenPGP.
(convert_to_openpgp): It's "ecc".
* agent/gpg-agent.c (map_pk_openpgp_to_gcry): Remove.
* g10/call-agent.c (agent_pkdecrypt): Fix off-by-one error.
* g10/pubkey-enc.c (get_it): Fix swapping the fields error.
* agent/gpg-agent.c (main): Make sure homedir is absolute.
* common/asshelp.c (lock_spawning): Create lock file with an absolute
name.
(start_new_gpg_agent): Use an absolute name for the socket and pass
option --homedir to the agent.
(start_new_dirmngr): Use an absolute name for the --homedir.
--
This patch makes gpg's --homedir option behave again like in older
versions. This is done by starting a new agent for each different
home directory. Note that this assumes --use-standard-socket is used
which is the default for 2.1.
* g10/call-agent.c (check_hijacking): New.
(start_agent): Call it.
(membuf_data_cb, default_inq_cb): Move more to the top.
--
Note that GUIs may use the gpg status line
[GNUPG:] ERROR check_hijacking 33554509
to detect this and print an appropriate warning.
* g10/photoid.c (show_photos): Set namehash.
* g10/misc.c (pct_expando): Add "%U" expando.
--
This makes is possible to extract all photos ids from a key to
different files.
* common/estream.c (es_freopen): Remove useless check for STREAM.
* kbx/keybox-blob.c (_keybox_create_x509_blob): Remove useless check
for BLOB.
* tools/sockprox.c (run_proxy): Do not fclose(NULL).
--
Found by Hans-Christoph Steiner with cppcheck.
* agent/cvt-openpgp.c (convert_to_openpgp): Fix use
gcry_sexp_extract_param.
* g10/export.c (do_export_stream): Provide a proper prompt to the
agent.
--
NB: The export needs more work, in particular the ECC algorithms.
* g10/passphrase.c (gpg_format_keydesc): Add mode 2. Change strings.
* g10/keydb.h (FORMAT_KEYDESC_NORMAL, FORMAT_KEYDESC_IMPORT)
(FORMAT_KEYDESC_EXPORT): New. Use them for clarity.
--
The use of the term "certificate" was more confusing than helpful.
* scd/app-openpgp.c (KEY_TYPE_EDDSA, CURVE_ED25519): New.
(struct app_local_s): Add eddsa.
(get_algo_byte, store_fpr): Support KEY_TYPE_EDDSA.
(get_ecc_key_parameters, get_curve_name): Support CURVE_ED25519.
(send_key_attr, get_public_key): Support KEY_TYPE_EDDSA.
(build_ecc_privkey_template): Rename as it supports both of
ECDSA and EdDSA.
(ecc_writekey): Rename. Support CURVE_ED25519, too.
(do_writekey): Follow the change of ecc_writekey.
(do_auth): Support KEY_TYPE_EDDSA.
(parse_ecc_curve): Support CURVE_ED25519. Bug fix for other curves.
(parse_algorithm_attribute): Bug fix for ECDH. Support EdDSA.
* common/mischelp.h (JNLIB_GCC_HAVE_PUSH_PRAGMA): New.
* dirmngr/dirmngr.c (handle_tick): Factor time check out to ...
(time_for_housekeeping_p): new.
--
I am not sure whether that y2038 hack is really useful but it might
make me smile in my retirement.
* agent/command-ssh.c (ssh_read_key_public_from_blob): Use
es_fopenmem.
(ssh_handler_request_identities): Ditto.
(ssh_request_process): Ditto.
--
es_fopenmem is easier to understand than the more general function
es_mopen. Thus we better use the former for clarity.
* agent/command-ssh.c (ssh_key_type_spec): Add field name.
(ssh_key_types): Add human readable names.
(add_control_entry): Add arg SPEC and print key type as comment.
(ssh_identity_register): Add arg SPEC.
(ssh_handler_add_identity): Add var SPEC and pass ssh_receive_key.
* agent/command-ssh.c (SPEC_FLAG_IS_EdDSA): New.
(ssh_key_types): Add entry for ssh-ed25519.
(ssh_identifier_from_curve_name): Move to the top.
(stream_read_skip): New.
(stream_read_blob): New.
(ssh_signature_encoder_rsa): Replace MPIS array by an s-exp and move
the s-exp parsing to here.
(ssh_signature_encoder_dsa): Ditto.
(ssh_signature_encoder_ecdsa): Ditto.
(ssh_signature_encoder_eddsa): New.
(sexp_key_construct): Rewrite.
(ssh_key_extract): Rename to ...
(ssh_key_to_blob): .. this and rewrite most of it.
(ssh_receive_key): Add case for EdDSA.
(ssh_convert_key_to_blob, key_secret_to_public): Remove.
(ssh_send_key_public): Rewrite.
(ssh_handler_request_identities): Simplify.
(data_sign): Add rename args. Add new args HASH and HASHLEN. Make
use of es_fopenmen and es_fclose_snatch. Remove parsing into MPIs
which is now doe in the sgnature encoder functions.
(ssh_handler_sign_request): Take care of Ed25519.
(ssh_key_extract_comment): Rewrite using gcry_sexp_nth_string.
--
To make the code easier readable most of the Ed25591 work has been
done using a new explicit code path. Warning: Libgcrypt 1.6.1 uses a
non optimized implementation for Ed25519 and timing attacks might be
possible.
While working on the code I realized that it could need more rework;
it is at some places quite baroque and more complicated than needed.
Given that we require Libgcrypt 1.6 anyway, we should make more use of
modern Libgcrypt functions.
* dirmngr/dirmngr.c (HOUSEKEEPING_INTERVAL): New.
(housekeeping_thread): New.
(handle_tick): Call new function.
* dirmngr/ks-engine-hkp.c (RESURRECT_INTERVAL): New.
(struct hostinfo_s): Add field died_at and set it along with the dead
flag.
(ks_hkp_print_hosttable): Print that info.
(ks_hkp_housekeeping): New.
--
The resurrection gives the host a chance to get back to life the next
time a new host is selected.
* dirmngr/ks-engine-hkp.c (ks_hkp_get): Allow exact search mode.
* g10/keyserver.c (keyserver_import_name): Implement.
(keyserver_get): Use exact mode for name based import.
(keyserver_get): Add args R_FPR and R_FPRLEN. Change all callers.
* dirmngr/ks-engine-hkp.c (ks_hkp_search, ks_hkp_get): Print SOURCE
status lines.
* g10/call-dirmngr.c (ks_status_parm_s): New.
(ks_search_parm_s): Add field stparm.
(ks_status_cb): New.
(ks_search_data_cb): Send source to the data callback.
(gpg_dirmngr_ks_search): Change callback prototope to include the
SPECIAL arg. Adjust all users. Use ks_status_cb.
(gpg_dirmngr_ks_get): Add arg r_source and use ks_status_cb.
* g10/keyserver.c (search_line_handler): Adjust callback and print
"data source" disgnostic.
(keyserver_get): Print data source diagnostic.
--
It has often been requested that the actually used IP of a keyservers
is shown in with gpg --recv-key and --search-key. This is helpful if
the keyserver is actually a pool of keyservers. This patch does this.
