* src/engine-spawn.c (add_data): Fix malloc
--
Bummer. Why did I subtracted one from the size? Did I assume a
dynamically allocated structure with a string field which was not
going to be used? Very strange.
Not a real problem though because malloc will anyway round up the
allocation to at least the next word size.
Detected by Stack 0.3.
* src/context.h (OPDATA_EXPORT): New.
* src/export.c (op_data_t): New.
(release_op_data): New.
(parse_error): New.
(export_status_handler): New.
(export_start, export_ext_start): Prepare op_data.
(gpgme_op_export_ext, gpgme_op_export_keys): Return an error from the
status handler.
--
To support an error return also for the async functions we need to
extend the API. Until we have done that this new features helps at
least in some cases; in particular for --send-keys.
* src/sign.c (gpgme_op_sign_result): Reformat and take care of failed
malloc.
--
Although _gpgme_debug_trace() is current always true, the code should
be run always and not just in trace mode. Also added error checking
to malloc and strdup. And while at replace some while by for loop for
easier readability.
* src/sign.c (gpgme_op_sign_result): Test that invalid and valid
signatures add up to gpgme_signers_count().
--
When invalid and valid signatures do not equal gpgme_signers_count() it
means that there was a bad passphrase during signing after the first
signer. This leaves the result.signatures from previous signers intact
which isn't correct since gpg will report:
gpg: number of one-pass packets does not match number of signature
packets
gpg: can't handle this ambiguous signature data
during verify. So when this happens append the valid signatures to the
.invalid_signers list with .reason set to GPG_ERR_GENERAL.
--
The --no-sk-comments flag is (or should be) a no-op in modern versions
of gnupg, but gpgme should still use its full form rather than the
(slightly) abbreviated --no-sk-comment
* src/engine-gpgsm.c (status_handler):
* src/engine-uiserver.c (status_handler):
--
After a realloc (realloc is also used for initial alloc) the allocated
size if the buffer is not correctly recorded. Thus an overflow can be
introduced by receiving data with different line lengths in a specific
order. This is not easy exploitable because libassuan constructs the
line. However a crash has been reported and thus it might be possible
to constructs an exploit.
CVE-id: CVE-2014-3564
Reported-by: Tomáš Trnka
* src/gpgme.h.in (GPGME_KEYLIST_MODE_WITH_SECRET): New.
* src/engine-gpg.c (gpg_keylist_build_options): Handle new mode.
* src/engine-gpgsm.c (gpgsm_keylist, gpgsm_keylist_ext): Ditto.
* src/keylist.c (parse_sec_field15): Add arg key and take care of
--with-secret output.
* src/gpgme-tool.c (gt_get_keylist_mode, cmd_keylist_mode): Add
"with_secret". Print card info and and secret flag for subkeys.
--
Note: This mode may only be used with GnuPG >= 2.1.
* src/gpgme.h.in (struct _gpgme_subkey): Add field CURVE.
* src/key.c (gpgme_key_unref): Free CURVE.
* src/keylist.c (keylist_colon_handler): Set CURVE.
* src/gpgme.c (gpgme_release): For failsafe reasons reset engine and
engine info after freeing.
--
The engine hack is useful in case the other release functions
accidently call engine release.
* src/engine-spawn.c (engspawn_start): Allocate space for list
terminator.
* src/posix-util.c (walk_path): Fix trailing slash detection.
--
Kudos to Valgrind for pointing out these two problems.
The first is a plain allocation bug in a code pattern I have written
thousands of times - this time it went wrong. The allocation is not
user controlled thus not directly exploitable.
The second is missed to do what it intended to do. Found due to the
access of malloced but not initialized memory. Not using calloc
again proved to be helpful to detect logical error.
* src/w32-io.c (create_writer): Free CTX in cased of bad FD.
* src/w32-util.c (_gpgme_mkstemp): Free TMPNAME in case of a failed
mkstemp.
--
Found by Hans-Christoph Steiner with cppcheck.
* src/spawn.c (gpgme_op_spawn_start, gpgme_op_spawn): Pass FLAGS dow
to spawn_start and add FLAGS args along the call path.
* src/engine-spawn.c (engspawn_start): Hack to automagically provide
argv[0].
* src/posix-io.c (_gpgme_io_spawn): dup /dev/null also to unsued
stdout.
--
Better be sure that stdout of a spawned process is connected to stdout
so that the process does not run into a write error if it writes to
stdout. AFAICS we always use a connected stdout; thus this is only
for correctness.
* configure.ac: Add option --enable-fixed-path.
(FIXED_SEARCH_PATH): New ac_define.
* src/posix-util.c (walk_path): Make use of the option. Remove
current directory from fallback PATH.
--
Note that using this option PATH is entirely ignored by GPGME and only
the given value is used instead to locate the GnuPG binaries.
On Android the use of PATH is not desirable. Instead the GnuPG tools
are expected in a fixed directory. By using
./configure --enable-fixed-path="/foo/bar"
gpg et al are expected to be installed as /foo/bar/gpg. With
./configure --enable-fixed-path="/foo/bar:/bin"
gpg is expected as /foo/bar/gpg or /bin/gpg.
* src/dirinfo.c (WANT_GPG_ONE_MODE): New.
(struct dirinfo): Add field "gpg_one_mode".
(get_gpgconf_item): Set that field and return it if requested.
(_gpgme_in_gpg_one_mode): New.

* src/engine-gpgsm.c (gpgsm_new): Ditto.
* src/engine-gpg.c (build_argv): Ditto. Add arg PGMNAME.
(start): Pass PGMNAME to buildargv.
* src/gpgme.c (gpgme_set_global_flag): Add names "disable-gpgconf",
"gpgconf-name", and "gpg-name".
* src/dirinfo.c (_gpgme_dirinfo_disable_gpgconf): New.
(get_gpgconf_item): Minor debug info change.
* src/posix-util.c (default_gpg_name, default_gpgconf_name): Add vars.
(_gpgme_set_default_gpg_name): New.
(_gpgme_set_default_gpgconf_name): New.
(_gpgme_get_gpg_path, _gpgme_get_gpgconf_path): Use new vars.

options.
--
Note that the Windows part has not been tested.
* configure.ac (NEED_GPG_VERSION, NEED_GPGSM_VERSION)
(NEED_G13_VERSION, NEED_GPGCONF_VERSION): Remove vars and all related
checks. Do not check for any engine version.
(HAVE_ASSUAN): Remove AM conditional.
* src/Makefile.am: Remove separate component vars and always build all
engines but uiserver.
* src/dirinfo.c (WANT_GPGCONF_NAME): New.
(struct dirinfo): Add field gpgconf_name.
(_gpgme_get_default_gpgconf_name): Use WANT_GPGCONF_NAME.
(get_gpgconf_item): Set gpgconf name and adjust for _gpgme_get_*_path
now returning a malloced string.
* src/engine.c (engine_ops): Always init all engines except for
uiserver.
* src/posix-util.c (_gpgme_get_gpgsm_path, _gpgme_get_g13_path):
Remove unused functions.
(walk_path): New.
(_gpgme_get_gpg_path, _gpgme_get_gpgconf_path ): Re-implement using
walk_path.
* src/w32-util.c (_gpgme_get_gpgsm_path, _gpgme_get_g13_path): Remove
unused functions.
(_gpgme_get_gpg_path, _gpgme_get_gpgconf_path): Return a malloced
string.
* src/engine-g13.c (g13_get_req_version): Use a hardwired string with
the required version. This info belongs into this file.
* src/engine-gpg.c (gpg_get_req_version): Ditto.
* src/engine-gpgconf.c (gpgconf_get_req_version): Ditto.
* src/engine-gpgsm.c (gpgsm_get_req_version): Ditto.
* tests/t-engine-info.c: Replace now useless test by an info output.
* tests/gpg/Makefile.am (GPG, GPG_AGENT): Hardwire gpg and gpg-agent.
* tests/gpgsm/Makefile.am (GPGSM): Hardwire gpgsm.

* src/libgpgme.vers, src/gpgme.def: Add gpgme_data_identify.
* src/gpgme-tool.c (status): Add STATUS_IDENTIFY_RESULT.
(gt_identify): New.

(hlp_passwd): Move close to cmd_passwd.
--
It is often useful to have a way to identify the data which needs
processing. This is such a common task that it makes sense to
implement this in gpgme to avoid diverging implementations.
* src/util.h: Move some prototypes to ...
* src/sys-util.h: New.
* src/Makefile.am (main_sources): Add sys-util.h.
* configure.ac (AH_VERBATIM): Add DIRSEP_C and DIRSEP_S.
* src/dirinfo.c: Include sys-util.h.
(WANT_GPG_NAME, WANT_GPGSM_NAME, WANT_G13_NAME)
(WANT_UISRV_SOCKET): New.
(dirinfo): Add corresponding fields.
(parse_output): Add arg COMPONENTS and set new fields.
(read_gpgconf_dirs): Add arg components and act upon it.
(get_gpgconf_item): Call read_gpgconf_dirs two times. Add debug
output.

(_gpgme_get_default_g13_name): New.
(_gpgme_get_default_gpgconf_name): New.
(_gpgme_get_default_uisrv_socket): New.
* src/engine-gpg.c, src/engine-g13.c, src/engine-gpgconf.c
* src/engine-gpgsm.c, src/engine-uiserver.c: Change to use
_gpgme_get_default_ instead of those from sys-util.h.
* src/posix-util.c (_gpgme_get_gpg_path): Include sys-util.h.
(_gpgme_get_uiserver_socket_path): Remove.
* src/w32-util.c (_gpgme_get_gpg_path): Include sys-util.h.
(_gpgme_get_uiserver_socket_path): Remove.
--
The default engines names are now taken from the output of gpgconf.
If gpgconf is not installed gpg 1 is assumed and locate the same was
as gpgconf.
* src/gpgme.h.in: Move gpgme_sssize_t and gpgme_off_t typedefs into
the extern "C" scope.
--
Frankly, this does not help very much because g++ still does not
interpret gpgme_data_seek_cb_t as compatible with the C++ ssize_t. I
am sorry for that API change but C and C++ are too different to always
get both of them under one umbrella. However, the ABI should now be
identical to older gpgme versions.
* configure.ac (NEED__FILE_OFFSET_BITS): Change to define gpgme_off_t
and gpgme_ssize_t.
(API__OFF_T, API__SSIZE_T): New ac_subst.
* src/gpgme.h.in: Replace all ssize_t and off_t by ac_subst macros.
* src/assuan-support.c, src/ath-pthread.c, src/ath.c, src/ath.h
* src/data-compat.c, src/data-fd.c, src/data-mem.c, src/data-stream.c
* src/data-user.c, src/data.c, src/data.h, src/engine-gpgsm.c
* src/engine-uiserver.c, src/gpgme-tool.c, src/gpgme.c: Replace off_t
by gpgme_off_t and sszie_t by gpgme_ssize_t.
* src/ath-pthread.c, src/ath.h: Include gpgme.h.
--
For a detailed description, see the gpgme.texi diff.
* src/w32-io.c (reader_context_s, create_reader)
(writer_context_s, create_writer): Rename STOPPED to CLOSE_EV.
(reader, writer): Remove setting of STOPPED. Wait for CLOSE_EV and
then release the context.
(destroy_reader, destroy_writer): Do not wait but set the CLOSE_EV.
(kill_reader, kill_writer): Remove.
(_gpgme_io_close): Add code from kill_reader and kill_writer.
--
The old code was prone to deadlocks which were actually exhibited at
Kleopatra startup. The new code is much more straightforward and
easier to understand. The reason for the complex old code was
probably due to our former idea to allow re-use of the I/O threads.
However we have long given up on this.
* configure.ac (INSERT__TYPEDEFS_FOR_GPGME_H): Add hacks for 32 bit
mingw64.
* src/util.h [W32]: Include winsock2.h before windows to make mingw64
happy.
* src/w32-util.c (_WIN32_IE): Need to use 5.1 for mingw64.
--
It is not clear to me what mingw64 wants to achieve with their POSIX
hacks. In particular the off64_t stuff looks quite strange given that
Windows has a pretty stable API for close to 2 decades. Thus I can't
say whether it will really work when build with that toolchain.
* configure.ac: Rename my_foo variables to mym4_foo variables to make
clear that they are processed by m4.
(VERSION_NUMBER): New ac_subst.
(AH_BOTTOM): Add CRIGHTBLURB macro.
(BUILD_REVISION, BUILD_FILEVERSION, BUILD_TIMESTAMP): Change them to
work similar to libgpg-error et al.
* src/versioninfo.rc.in: Remove use of BUILD_NUMBER and get it in line
with gpg-error et al.
* src/version.c (cright_blurb): New.
(gpgme_check_version_internal): Add magic to display the above
information.
* tests/t-version.c (main): Add option --verbose.
* src/gpgme.c (gpgme_set_pinentry_mode): New.
* src/gpgme.h.in (gpgme_pinentry_t): New.
(gpgme_set_pinentry_mode): New.
* src/context.h (struct gpgme_context): Add field pinentry_mode.
* src/engine-backend.h (struct engine_ops): Add field
set_pinentry_mode.
* src/engine-gpg.c (struct engine_gpg): Add field pinentry_mode.
(build_argv): Implement pinentry_mode.
(gpg_set_pinentry_mode): New.
(_gpgme_engine_ops_gpg): Register gpg_set_pinentry_mode.
--
Note that this new fucntion may only be used with gpg 2.1.
* src/gpgme.c (gpgme_io_read): New.
--
This is a writen style variant for gpgme_io_write. It is often easier
to use this one in passphrase and edit callbacks.
* src/conversion.c (D_gpgme_encode_percent_string): Remove stray
semicolon. Reported by Xi Wang.
--
Obviously this function is not used with a supplied LEN argument != 0.
* configure.ac: Define macro and conditional HAVE_ANDROID_SYSTEM.
* m4/gnupg-ttyname.m4: Force use of replacement on Android.
* src/ttyname_r.c: Ditto.
--
Android's bionic lib has no working ttyname_r() nor ttyname(). Using
them anyway will print
FIX ME! implement ttyname_r() bionic/libc/bionic/stubs.c:466
Thus we force the use of our replacement code which simply return
"/dev/tty".
* src/debug.h: Include "gpgme.h"
(_gpgme_trace_gpgme_error): New.
(trace_gpg_error): New macro. Use it in all files where we return
GPG_ERR_INV_ENGINE; also "include debug.h" as needed.
--
This is a pretty common error code but often it is hard to figure out
the actual cause. With debug level 4 we now print the file name and
line number where this error code is generated by gpgme. Along with
the git revision printed in the first log lines, this should give us
an easier way to track down the problems related to this error code.
* src/gpgme-tool.c (clear_membuf, init_membuf, put_membuf)
(put_membuf_str, get_membuf, peek_membuf): Add membuf functions.
Take from GnuPG master's common/membuf.[ch] and patch for our use.
(result_xml_escape): Rewrite using new functions.
--
First counting, then allocating, and finally copying data is prone to
errors. We better use the membuf functions which make it much easier.
* src/gpgme-tool.c: Change license notice.
--
gpgme-tool.c is a standalone program, thus it makes no sense to keep
it under the LGPL. We already had the manual under GPLv3+.
[[PGP Signed Part:Undecided]]
src/gpgme-tool.c (result_xml_escape_replacement, result_xml_escape):
New.
(result_xml_tag_data): Use result_xml_escape() to escape data.
(result_add_error): Use unescaped < and >.
--
This is a general solution for generating valid XML, but the specific
output that inspired the change was from the KEYLIST command:
<uid>William Trevor King <wking@tremily.us></uid>

(result_add_protocol, result_add_validity): New functions for

(result_add_string): Treat NULL strings as "".
(result_xml_tag_data): Make 'data' a 'const char' so we can use the

(_cmd_decrypt_verify, _cmd_sign_encrypt, cmd_verify, cmd_import)
(cmd_export, cmd_genkey, cmd_getauditlog): Use SERVER object instead
of assuan_get_*_fd functions.
--
Although we used our own handlers for INPUT and OUTPUT, we still used
assuan_get_input_fd, assuan_get_output_fd and their close functions.
That clearly can't work because libassuan does not have any values for
them.
* src/gpgme.c (gpgme_set_global_flag): New.
* src/gpgme.h.in (gpgme_set_global_flag): New.
* src/gpgme.def, src/libgpgme.vers: Add new public function.
* src/debug.c (envvar_override): New.:
(_gpgme_debug_set_debug_envvar): New.
(debug_init): Take ENVVAR_OVERRIDE in account.
--
On Android envvars can't be used, thus we need another way to enable
GPGME debugging. The new function allows this and may be used in the
future to implement similar things.
* src/engine-uiserver.c: Remove status-table.h which is not anymore
built. Fixes bug#1412.
--
The file was actually removed from the code by 885243e0 but for
unknown reasons the missing file was not reported by "make distcheck".
* src/engine-gpgconf.c (arg_to_data): Allow for NULL as value.string.
--
I was not able to replicate the problem. However this patch makes the
code more robust and tolerates errors by the user. IT should fix the
problem at hand.
* src/verify.c (gpgme_op_verify_result): Update summary field.
--
This is actually a hack to solve the problem that GPGME currently does
not emit ERRSIG for a missing public key.
* m4/gnupg-ttyname.m4: New. Based on ttyname_r from gnulib.
* src/ttyname_r.c (_gpgme_ttyname_r): Rename from ttyname_r.
Implement hacks required for Solaris and possible other non-fully
Posix systems.
* src/util.h: Include unistd.h. Redefine ttyname_r depending on
REPLACE_TTYNAME_R and put it into the gpgme name space.
--
Unfortunately we cant not use the ttyname_r replacement from gnulib
because we want to keep GPGME LGPLv2+.
We would need to use a shortened commit id so that it fits into an 16
bit Windows variable. Further it is a random number and not something
increasing. Thus a build number made up from the day of the year and
the hour is much more useful to describe a build number for a specific
revision.
* configure.ac [W32]: Replace BUILD_REVISION by BUILD_NUMBER.
* src/versioninfo.rc.in: Ditto.
* build-aux/gitlog-to-changelog: New script. Taken from gnulib.

* autogen.sh: Install commit-msg hook for git.
Rename all ChangeLog files to ChangeLog-2011.
gpgme-config.in: Add option --host. Change options --cflags and
--libs to collapse duplicate include and lib dirs. Try to put extra
libs at the end.
Note that gpgme.m4 has not yet been extended.
