6cbc75e712 mpi: Avoid data-dependent timing variations in mpi_powm.
* include/mpi.h, mpi/mpiutils.c (mpi_set_cond): New.
* mpi/mpi-pow.c (SIZE_PRECOMP): Rename from SIZE_B_2I3.
(mpi_powm): Access all data in the table and use mpi_set_cond.

--

Access to the precomputed table was indexed by a portion of EXPO,
which could be mounted by a side channel attack.  This change fixes
this particular data-dependent access pattern.

Use inline functions to convert buffer data to scalars.
* include/host2net.h (buf16_to_ulong, buf16_to_uint): New.
(buf16_to_ushort, buf16_to_u16): New.
(buf32_to_size_t, buf32_to_ulong, buf32_to_uint, buf32_to_u32): New.
--

This fixes sign extension on shift problems.  Hanno Böck found a case
with an invalid read due to this problem.  To fix that almost all uses
of "<< 24" and "<< 8" are changed by this patch to use an inline
function from host2net.h.

b89f57fe5d mpi: Suppress set-but-unused-variables warnings.
* include/types.h (GNUPG_GCC_ATTR_UNUSED): Define for gcc >= 3.5.
* mpi/mpih-div.c (mpihelp_divmod_1, mpihelp_mod_1): Mark dummy as
 unused.
* mpi/mpi-internal.h (UDIV_QRNND_PREINV): Mark _ql as unused.
--

Due to the use of macros and longlong.h, we use variables which are
only used by some architectures.  At least gcc 4.7.2 prints new
warnings about set but not used variables.  This patch silences them.

27d0f32f77 gpg: Distinguish between missing and cleared key flags.
* include/cipher.h (PUBKEY_USAGE_NONE): New.
* g10/getkey.c (parse_key_usage): Set new flag.
--

We do not want to use the default capabilities (derived from the
algorithm) if any key flags are given in a signature.  Thus if key
flags are used in any way, the default key capabilities are never
used.

This allows to create a key with key flags set to all zero so it can't
be used.  This better reflects common sense.

* include/cipher.h (PUBKEY_ALGO_ECC): New.
* g10/keyid.c (pubkey_letter): Add letter 'C'.

ID 22 will be used for generic ECC, i.e. one which can be used for
ECDSA and ECDH.  The only support in 1.4 will pretty printing the
algorithm id.

212a325d42 gpg: signal handling fix
* include/dotlock.h (dotlock_remove_lockfiles_reclaim): New.
  (dotlock_destroy, dotlock_remove_lockfiles): Add a flag to reclaim
  memory or not.
* util/dotlock.c (dotlock_create): Use
  dotlock_remove_lockfiles_reclaim for atexit.
  (dotlock_destroy_unix, dotlock_destroy)
  (dotlock_remove_lockfiles): Add a reclaim flag.
  (dotlock_remove_lockfiles_reclaim): New.
* g10/signal.c (got_fatal_signal): Disable flag of reclaim memory to
  avoid non-async-face call.
* g10/keydb.c (maybe_create_keyring): Follow the API change.
* g10/gpgv.c: Follow the API change.

--

signal handler got_fatal_signal should not call non-async-signal-safe
functions.  When malloc is interrupted by a signal, it screws up.

f2f12f41ef Fix issue 1446: honor ports given in SRV responses.
* common/http.c (send_request, connect_server, http_open): Use a
  struct srv instead of a single srvtag so we can pass the chosen host
  and port back to the caller.
  (connect_server): Use the proper port in the HAVE_GETADDRINFO case.

* keyserver/curl-shim.c (curl_easy_perform): Use struct srv and log
  chosen host and port.

* keyserver/gpgkeys_hkp.c (main): Properly take the port given by SRV.

8044a5acea Add meta option ignore-invalid-option.
* util/argparse.c (iio_item_def_s, IIO_ITEM_DEF): New.
(initialize): Init field IIO_LIST.
(ignore_invalid_option_p): New.
(ignore_invalid_option_add): New.
(ignore_invalid_option_clear): New.
(optfile_parse): Implement meta option.
--

This option is currently of no use.  However, as soon as it has been
deployed in all stable versions of GnuPG, it will allow the use of the
same configuration file with an old and a new version of GnuPG.  For
example: If a new version implements the option "foobar", and a user
uses it in gpg.conf, an old version of gpg would bail out with the
error "invalid option".  To avoid that the following line can be put
above that option in gpg.conf

  ignore-invalid-option foobar

This meta option may be given several times or several option names
may be given as arguments (space delimited).  Note that this option is
not available on the command line.

e33e74e3a4 Fix potential heap corruption in "gpg -v --version"
* g10/gpg.c (build_list): Rewrite to cope with buffer overflow in
certain locales.
* util/membuf.c (put_membuf_str): New.
(get_membuf): Make LEN optional.
--

This fixes an obvious bug in locales where the translated string is
longer than the original.  The bug could be exhibited by using
LANG=ru_RU.utf8 gpg -v --version.

En passant we also removed the trailing white space on continued
lines.

6a41f385c4 Handle systems which have uint64_t but not the UINT64_C macro.
* include/types.h (U64_C) [!UINT64_C]: Add simple replacement.

--
This could happen with UNIX98-type systems, such as the code on
the netbsd-1-5 branch, and would prevent this package from building
on such systems.

functions.  Define HAVE_POSIX_SYSTEM.  Rearrange some functions.

04b0b050ff Add pubkey letters e and E for ECC.
This does not mean we have any kind of ECC support now.  It is merely
to avoid printing a question mark for the algorithm.

Trailing white space changes as usual.

3459c6b015 First set of changes to backport the new card code from 2.0.
For compatibility reasons a few new files had to be added.
Also added estream-printf as this is now used in app-openpgp.c and provides
a better and generic asprintf implementation than the hack we used for the
W32 code in ttyio.c.  Card code is not yet finished.

(obviously), and it's a great way to lose your data.  Just don't do
it.

copy of libcompat.a so we only need to link to one of them.
