the token string from the wrong field 14 to 15.
--

This option is useful for key managers which need to know whether a
key has a secret key.  This change allows to collect this information
in one pass.

Werner Koch 958e5f292f gpg: Avoid NULL-deref in default key listing.
* g10/keyid.c (hash_public_key): Take care of NULL keys.
* g10/misc.c (pubkey_nbits): Ditto.
--

This problem was mainly due to our ECC code while checking for opaque
MPIs with the curve name.

Werner Koch d9cde7ba7d gpg: Graceful skip reading of corrupt MPIs.
* g10/parse-packet.c (mpi_read): Change error message on overflow.
--

This gets gpg 2.x in sync to what gpg 1.4 does.  No need to die for a
broken MPI.

Resolved conflicts:
	g10/parse-packet.c - whitespaces fixes.

Werner Koch 715285bcbc gpgsm: Handle re-issued CA certificates in a better way.
* sm/certchain.c (find_up_search_by_keyid): Consider all matching
certificates.
(find_up): Add some debug messages.
--

The DFN-Verein recently re-issued its CA certificates without
generating new keys.  Thus looking up the chain using the authority
keyids works but may use still existing old certificates.  This may
break the CRL lookup in the Dirmngr.  The hack to fix this is by using
the latest issued certificate with the same subject key identifier.

As usual Peter Gutman's X.509 style guide has some comments on that
re-issuing.

Werner Koch 42c043a8ad gpgsm: Add a way to save a found state.
* kbx/keybox-defs.h (keybox_found_s): New.
(keybox_handle): Factor FOUND out to above.  Add saved_found.
* kbx/keybox-init.c (keybox_release): Release saved_found.
(keybox_push_found_state, keybox_pop_found_state): New.

* sm/keydb.c (keydb_handle): Add field saved_found.
(keydb_new): Init it.
(keydb_push_found_state, keydb_pop_found_state): New.

Werner Koch 99972bd6e9 gpg: Fix bug parsing a zero length user id.
* g10/getkey.c (get_user_id): Do not call xmalloc with 0.

* common/xmalloc.c (xmalloc, xcalloc): Take extra precaution not to
pass 0 to the arguments.
--

The problem did not occur in 1.x because over there the xmalloc makes
sure to allocate at least one byte.  With 2.x for most calls the
xmalloc of Libgcrypt is used and Libgcrypt returns an error insteead
of silent allocating a byte.  Thus gpg 2.x bailed out with an
"Fatal: out of core while allocating 0 bytes".

The extra code in xmalloc.c is for more robustness for the other
xmalloc calls.

Werner Koch 9e1c99f800 dirmngr: Print certificates on failed TLS verification.
* dirmngr/ks-engine-hkp.c (cert_log_cb): New.
(send_request): Set callback.
--

We use the KSBA functions here because we have them anyway in Dirmngr.
2014-05-19 09:48:42 +02:00
Werner Koch 45f15b2d76 http: Add callback to help logging of server certificates.
* common/http.c (http_session_s): Add field cert_log_cb.
(http_session_set_log_cb): New.
(http_verify_server_credentials): Call callback.
2014-05-19 09:47:18 +02:00
Werner Koch d2d9d4fb60 keyserver: Improve support for hkps pools.
* dirmngr/ks-engine-hkp.c (hostinfo_s): Add fields cname, v4addr, and
v6addr.
(create_new_hostinfo): Clear them.
(my_getnameinfo): Add args numeric and r_isnumeric.
(is_ip_address): New.
(map_host): Add arg r_host.  Rewrite the code to handle pools in a
special way.
(ks_hkp_print_hosttable): Change format of help info output.
(make_host_part): Add arg optional r_httphost.
(send_request): Add arg httphost.
(ks_hkp_search, ks_hkp_get, ks_hkp_put): Get httphost and pass it to
send_request.
--

This changes quite some things on how the hostinfo is maintained.
However, it might be better to rework the data structures and have one
entry per IP address instead of this clumsy patch.
2014-05-16 21:15:40 +02:00
Werner Koch 8b90d79818 http: Allow overriding of the Host header.
* common/http.c (http_open): Add arg httphost.
(http_open_document): Pass NULL for httphost.
(send_request): Add arg httphost.  If given, use HTTPHOST instead of
SERVER.  Use https with a proxy if requested.
(http_verify_server_credentials): Do not stop at the first error
message.
* dirmngr/ocsp.c (do_ocsp_request): Adjust call to http_open.
* keyserver/curl-shim.c (curl_easy_perform): Ditto.
* dirmngr/ks-engine-http.c (ks_http_fetch): Ditto.
* dirmngr/ks-engine-hkp.c (ks_hkp_help): Ditto.
2014-05-16 21:01:08 +02:00
Werner Koch 25036ec6ab gpg: Fix uninitialized access to search descindex with gpg keyboxes.
* kbx/keybox-search.c (keybox_search): Add arg  R_DESCINDEX.  Chnage
both callers.
* g10/keydb.c (keydb_search): Always set DESCINDEX.
--

This only affects the new keybox for OpenPGP keys in 2.1.  The bug
exhibited itself by running GPA's backup command on Windows.
2014-05-14 18:13:11 +02:00
Werner Koch 71fa6a3510 w32: Make make_absfilename work with drive letters.
* common/stringhelp.c (do_make_filename) [HAVE_DRIVE_LETTERS]: Fix.
2014-05-14 18:13:07 +02:00
Werner Koch 455a4a2212 gpg: Remove useless diagnostic in MDC verification.
* g10/decrypt-data.c (decrypt_data): Do not distinguish between a bad
MDC packer header and a bad MDC.
--

The separate diagnostic was introduced for debugging a problems.  For
explaining an MDC error a single error message is easier to
understand.
2014-05-14 08:56:39 +02:00
Werner Koch b2945c451d gpg: Fix glitch entering a full expiration time.
* g10/keygen.c (ask_expire_interval): Get the current time after the
prompt.
--

This almost avoid that an entered full ISO timestamp is not used as
given but off by the time the user required to enter the timestamp.

non-protected keys.
(convert_from_openpgp_main): Do not call agent_askpin for a
non-protected key.

(convert_from_openpgp_main): Ditto.
(convert_to_openpgp):  Simplify.
* g10/import.c (one_mpi_from_pkey): Remove.

* kbx/keybox-openpgp.c (parse_key): Use algo constants and add
experimental support for EdDSA.
2014-05-07 12:39:43 +02:00
Werner Koch a63ed98758 agent: Remove greeting message.
* agent/gpg-agent.c (main): Remove greeting.  Make --no-greeting a
dummy.
2014-05-07 08:51:11 +02:00
Werner Koch 6477e51919 Use "samethread" mode keyword for some es_fopenmem.
* dirmngr/ks-engine-hkp.c (armor_data): Add mode keyword.

* dirmngr/dirmngr.c: Include gnutls.h.
(opts): Add --gnutls-debug and --hkp-cacert.
(opt_gnutls_debug, my_gnutls_log): New.
(set_debug): Set gnutls log level.
(parse_rereadable_options): Register a CA file.
(main): Init GNUTLS.
* dirmngr/ks-engine-hkp.c (ks_hkp_help): Support hkps.
(send_request): Ditto.
2014-05-05 16:23:37 +02:00
Werner Koch ea0f5481f0 http: Add reference counting to the session object.
* 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.
2014-05-05 16:06:42 +02:00
Werner Koch 0e59195642 http: Add HTTP_FLAG_FORCE_TLS and http_get_tls_info.

* common/t-http.c (main): Add several command line options.
2014-05-02 17:28:02 +02:00
Werner Koch 2def230231 common: Fix test for openpgp_oid_is_ed25519.
* common/t-openpgp-oid.c (test_openpgp_oid_is_ed25519): Add correct
value.
2014-05-02 14:07:03 +02:00
Werner Koch 8412a5825c http: Revamp TLS API.

(libcommontls_a_SOURCES): New.
(libcommontlsnpth_a_SOURCES): New.
(EXTRA_DIST): Add tls-ca.pem
(module_maint_tests): Add t-http.
(t_http_SOURCES, t_http_CFLAGS, t_http_LDADD): New.

* dirmngr/Makefile.am (dirmngr_LDADD): Add libcommontlsnpth.
--

This new TLS API for http.c is much more flexible than the crude old
hack.
2014-05-02 11:19:25 +02:00
Werner Koch 84289e85c7 common: Cleanup the use of USE_NPTH and HAVE_NPTH macros.
* 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.
2014-05-02 08:22:38 +02:00
Werner Koch 8416c875a7 estream: Implement "samethread" mode keyword.
* 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.
2014-04-30 21:14:28 +02:00
Werner Koch ecea94461e estream: Fix deadlock in es_fileno.
* src/estream.c (es_fileno_unlocked): Call the unlocked functions.

Werner Koch aeb81727c7 estream: Add debug code to the lock functions.
* common/estream.c (dbg_lock_0, dbg_lock_1, dbg_lock_1): New.
2014-04-30 21:14:28 +02:00
Werner Koch 39e91a5f0a estream: Replace locking macros by functions.
* common/estream.c: Replace most macros.
--

The macros were too hard to read and actually blew up the source.
2014-04-30 21:14:28 +02:00
Werner Koch 7296ccf3d5 estream: Migrate from Pth to nPth.
--

Actually the mutex stuff was never used since we switched to nPth.

Werner Koch 7adeae3ba3 gpg: Minor doc enhancement
--
2014-04-30 21:14:28 +02:00
NIIBE Yutaka 21dab64030 ECC Fixes.
* 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.
2014-04-28 10:36:16 +09:00
Werner Koch fdd938a5bb gpg: Pass --homedir to gpg-agent.
* 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.
2014-04-22 16:59:06 +02:00
Werner Koch 71a54313ad common: Add functions make_absfilename and make_absfilename_try.

(make_absfilename_try): New.
2014-04-22 15:58:33 +02:00
Werner Koch 1a87edab66 common: Add function gnupg_getcwd.
* tools/gpg-connect-agent.c (gnu_getcwd): Move to ...
* common/sysutils.c (gnupg_getcwd): .. here.
* tools/gpg-connect-agent.c (get_var_ext): Use gnupg_getcwd.
2014-04-22 15:02:05 +02:00
Werner Koch ffa39be5eb gpg: Print a warning if GKR has hijacked gpg-agent.
* 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.
