c8c88bdd98 gpg: Emit status line NEWSIG before signature verification starts.
* g10/mainproc.c (check_sig_and_print): Emit STATUS_NEWSIG.
--

gpgsm does this for a long time but somehow it never made it into gpg.

a5ca45e616 gpg: Make the use of "--verify FILE" for detached sigs harder.
* g10/openfile.c (open_sigfile): Factor some code out to ...
(get_matching_datafile): new function.
* g10/plaintext.c (hash_datafiles): Do not try to find matching file
in batch mode.
* g10/mainproc.c (check_sig_and_print): Print a warning if a possibly
matching data file is not used by a standard signatures.
--

Allowing to use the abbreviated form for detached signatures is a long
standing bug which has only been noticed by the public with the
release of 2.1.0.  :-(

What we do is to remove the ability to check detached signature in
--batch using the one file abbreviated mode.  This should exhibit
problems in scripts which use this insecure practice.  We also print a
warning if a matching data file exists but was not considered because
the detached signature was actually a standard signature:

  gpgv: Good signature from "Werner Koch (dist sig)"
  gpgv: WARNING: not a detached signature; \
  file 'gnupg-2.1.0.tar.bz2' was NOT verified!

We can only print a warning because it is possible that a standard
signature is indeed to be verified but by coincidence a file with a
matching name is stored alongside the standard signature.

ce989354fb gpg: Simplify default key listing.
* g10/mainproc.c (list_node): Rework.
--

The old code still merged the first user id into the key packet line
which resulted in all kind of complexity.  --fixed-list-mode is
meanwhile the default and thus we also change this part of the code.

3ae90ff28c gpg: Change --show-session-key to print the session key earlier.
* g10/cpr.c (write_status_strings): New.
(write_status_text): Replace code by a call to write_status_strings.
* g10/mainproc.c (proc_encrypted): Remove show_session_key code.
* g10/decrypt-data.c (decrypt_data): Add new show_session_key code.
--

This feature can be used to return the session key for just a part of
a file.  For example to downloading just the first 32k of a huge file,
decrypting that incomplete part and while ignoring all the errors
break out the session key.  The session key may then be used on the
server to decrypt the entire file without the need to have the private
key on the server.

6286d01ba3 gpg: Fix --version output and explicitly disable ECC.
* g10/misc.c (openpgp_pk_algo_name): New.  Replace all calls in g10/
to gcry_pk_algo_name by a call to this function.
(map_pk_openpgp_to_gcry): Map algo PUBKEY_ALGO_ELGAMAL_E to GCRY_PK_ELG.
(openpgp_pk_test_algo): Use PUBKEY_ALGO_ELGAMAL_E instead of
GCRY_PK_ELG_E.  Return an error for ECC algos.
(openpgp_pk_test_algo2):  Return an error for ECC algos.
* g10/gpg.c (build_list): Avoid printing ECC two times.
* include/cipher.h: Do not use GCRY_PK_* macros for PUBKEY_ALGO_*.
--

Due to recent changes to adjust for use with Libgcrypt 1.6, "gpg
--version" printed two question marks.  This patches fixes that and
also make sure that gpg does advertise any ECC features.  The patch in
build_list is not really needed.

35e40e2d51 gpg: Limit the nesting level of I/O filters.
* common/iobuf.c (MAX_NESTING_FILTER): New.
(iobuf_push_filter2): Limit the nesting level.

* g10/mainproc.c (mainproc_context): New field ANY.  Change HAVE_DATA
and ANY_SIG_SIGN to bit fields of ANY.  Add bit field
UNCOMPRESS_FAILED.
(proc_compressed): Avoid printing multiple Bad Data messages.
(check_nesting): Return GPG_ERR_BAD_DATA instead of UNEXPECTED_DATA.
--

This is a more general fix for the nested compression packet bug.  In
particular this helps g10/import.c:read_block to stop pushing
compression filters onto an iobuf stream.  This patch also reduces the
number of error messages for the non-import case.

Libgcrypt 1.6 will have some minor API changes.  In particular some
deprecated macros and functions will be removed.  PTH will also be
dropped in favor of a thread model neutral locking method.

Werner Koch
c0c2c58054 Finished the bulk of changes for gnupg 1.9. This included switching
to libgcrypt functions, using shared error codes from libgpg-error,
replacing the old functions we used to have in ../util by those in
../jnlib and ../common, renaming the malloc functions and a couple of
types.  Note, that not all changes are listed below becuause they are
too similar and done at far too many places.  As of today the code
builds using the current libgcrypt from CVS but it is very unlikely
that it actually works.
