Given that libgpg-error is a dependency of all GnuPG related libraries

macros, though.

--

Static strings in gpg-agent need to be translated according to the
locale set by the caller.  This is required so that a gpg-agent can be
started in one locale and a gpg can be run in another.  If we don't do
this the static strings (prompt, buttons) are not or in the wrong
locale translated while dynamic strings (e.g. key description) uses
the locale of gpg.

This is only the first part of the change the actual local switching
still needs to be implemented.

common: Minor change of hex2str to allow for embedded nul.
* common/convert.c (hex2str): Set ERRNO.  Return adjusted COUNT.
--

hex2str is only used at one place for in-place converting an hex
encoded passphrase.  This change does not affect this use.  The change
is however useful to use the function for in-place conversion of
arbitrary hex encoded strings.

Take care for in-place conversion of a hex string encoding binary data
you need to use it this way:

  if (hex2str (string, string, strlen (string) + 1, &length)
     oops ("probably out of memory but see ERRNO");
  for (i=0; i < length; i++)
     foo (string[i));

Note that strlen() + 1.

--

Note that although PKA is now always build, it will only work if
support for looking up via DNS has not been disabled.

The new PKA only works with the IPGP DNS certtype and shall be used
only to retrieve the fingerprint and optional the key for the first
time.  Due to the security problems with DNSSEC the former assumption
to validate the key using DNSSEC is not anymore justified.  Instead an
additional layer (e.g. Trust-On-First-Use) needs to be implemented to
track change to the key.  Having a solid way of getting a key matching
a mail address is however a must have.

More work needs to go into a redefinition of the --verify-options
pka-lookups and pka-trust-increase.  The auto-key-locate mechanism
should also be able to continue key fetching with another methods once
the fingerprint has been retrieved with PKA.

The idea with this change is that under Windows we can install a

version may then later install pinentry-gtk etc which would then
automatically be used.

Unfortunately installing another pinentry from a different package
would clobber the GnuPG core directory which is not nice.  To fix that
we would need to agree on standard installation directories for GUIs
to also look there.

367b073ab5 avoid future chance of using uninitialized memory
* common/iobuf.c: (iobuf_open): initialize len

--

In iobuf_open, IOBUFCTRL_DESC and IOBUFCTRL_INIT commands are invoked
(via file_filter()) on fcx, passing in a pointer to an uninitialized
len.

With these two commands, file_filter doesn't actually do anything with
the value of len, so there's no actual risk of use of uninitialized
memory in the code as it stands.

However, some static analysis tools might flag this situation with a
warning, and initializing the value doesn't hurt anything, so i think
this trivial cleanup is warranted.

628b111fa6 avoid double-close in unusual dotlock situations
* common/dotlock.c: (dotlock_create_unix) avoid double-close()
 in unusual situations.

--

close(2) says:

 close() should not be retried after an EINTR since this  may
       cause a reused descriptor from another thread to be closed.

Before this patch was applied, if close(fd) failed with EINTR, it
would be closed again in the write_failed: block.

It could also have been closed a second time in the case that
(use_hardlinks_p (h->tname)) evaluated to something other than 0 or 1.

This patch avoids both of those scenarios.

Note that close() could still be called twice on the same file
descriptor if the first close(fd) fails but errno is not EINTR.  I'm
not sure the right thing to do in that scenario.  An alternate
resolution could be to unequivocally set fd to -1 after the first
failed close(fd), avoiding the errno == EINTR test.

A remote connection is and should not be able to setup the local

The code has an obvious error by not considering invalid encoding for
arc-2.  A first byte of 0x80 can be used to make a value of less then
80 and we then subtract 80 from that value as required by the OID
encoding rules.  Due to the unsigned integer this results in a pretty
long value which won't fit anymore into the allocated buffer.

The fix is obvious.  Also added a few simple test cases.  Note that we
keep on using sprintf instead of snprintf because managing the
remaining length of the buffer would probably be more error prone than
assuring that the buffer is large enough.  Getting rid of sprintf
altogether by using direct conversion along with membuf_t like code
might be possible.

gnulib has always been a cause of trouble in GnuPG because we used
only a very few functions and the complex include machinery of gnulib
is quite complex and the cause for many build problems for example on
OS X.  This is not gnulib's fault but due to our limited use of gnulib
and that we only rarely update the gnulib code to avoid regressions.

In part two we will address the functions

 mkdtemp
 setenv
 unsetenv
 strpbrk

which may bot be implemented on all platforms.  They are not required

f2361e6d58 First changes for future use of NTBTLS.
* configure.ac (NEED_NTBTLS_ABI, NEED_NTBTLS_VERSION): New.
(HTTP_USE_NTBTLS): New.  Prefer over GNUTLS.
* m4/ntbtls.m4: New.
* m4/Makefile.am (EXTRA_DIST): Add new file.
* common/http.c: Add conditionals to eventually use NTBTLS.
--

This is only the configure stuff.  If you have NTBTLS installed GNUTLS
will not be used but there won't be any https support either :-(.
This patch is used to have a real world test bench for the forthcoming
library.

927db789c1 common: Do not build maintainer modules in non-maintainer mode.

cad181b5ec common: Remove superfluous statements.
* common/exechelp-posix.c: Remove weak pragmas.
* common/sexputil.c (make_canon_sexp_from_rsa_pk): Remove double

--

We do not use Pth anymore and thus there is no more need for the weak
pragmas.

83c2d2396c gpg: Use algorithm id 22 for EdDSA.
* common/openpgpdefs.h (PUBKEY_ALGO_EDDSA): Change to 22.
* g10/keygen.c (ask_curve): Reword the Curve25519 warning note.
--

In the hope that the IETF will eventually assign 22 for EdDSA using
the draft-koch-eddsa-for-openpgp-01 specs we start using this number.

3b20cc21de dirmngr: Fix the ks_fetch command for the http scheme.
* common/http.c (http_session_ref): Allow for NULL arg.
--

We always test for a an existing session and thus passing NULL as
session object should be allowed.

bf2fc12b83 gpg: Fix export of NIST ECC keys.
* common/openpgp-oid.c (struct oidtable): New.
(openpgp_curve_to_oid): Rewrite and allow OID as input.
(openpgp_oid_to_curve): Make use of the new table.
--

Due to the previous change we now usually store the OID with the
private key and not the name.  Thus during import we do not anymore
need to map the name to an oid but can use the oid directly.  We fix
that by extending openpgp_curve_to_oid to allow an oidstr as input.

519305feb8 Switch to the libgpg-error provided estream.

* m4/estream.m4: Remove.
* common/estream-printf.c, common/estream-printf.h: Remove.
* common/estream.c, common/estream.h: Remove.
* common/init.c (_init_common_subsystems): Call gpgrt initialization.

af1196512f estream: Change license from GPL to LPGL.
* common/estream-printf.c, common/estream-printf.h: Change license.
* common/estream.c, common/estream.h: Ditto.
--

g10 Code is the sole copyright holder of Libestream and thus as CEO I
have the rights to to change the license.  This copy here in GnuPG is
currently the most current one thus the change is recorded in this
repository.  This change is also deemed valid for all older versions.

* 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.

(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

* 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.

(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.

samethread.

This patch makes gpg's --homedir option behave again like in older

Our printf supports most of the GNU features and thus we can silence
the warnings from mingw.

The gpg server mode is not actual working and thus we can avoid the
warnings by explicitly disabling the mode.  We keep it working under
Unix, though.

Warning: estream.c still uses pth_mutex_* which is definitely wrong.

This patch enables support for Putty.  It has been tested with Putty
0.62 using an Unix created ssh key copied to the private-keys-v1.d
directory on Windows and with a manually crafted sshcontrol file.  It
also works with a smartcard key.

May thanks to gniibe who implemented a proxy in Python to test the
putty/gpg-agent communication.

In addition to the ignore-invalid-option (commit 41d56433) it is often
useful to mark options in a configuration which as NOP.  For example
options which have no more function at all but can be expected to be
found in existing conf files.  Such an option (or command) may now be
given as

  ARGPARSE_ignore (300, "obsolete-option")

The 300 is merely used as a non-valid single option name much like
group names or the 500+n values used for long options.
