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.

This option is in particular useful to convert from a pubring.gpg to
the new pubring.kbx in GnuPG 2.1 or vice versa:

MD5 is considered broken for a long time now. To make it easier for

This is a cherry-pick of 534e2876ac from
STABLE-BRANCH-1-4 against STABLE-BRANCH-2-0
Some older implementations built and used RSA keys up to 16Kib, but
the larger secret keys now fail when used by more recent GnuPG, due to
secure memory limitations.
Building with ./configure --enable-large-secmem will make gpg
capable of working with those secret keys, as well as permitting the
use of a new gpg option --enable-large-rsa, which let gpg generate RSA
keys up to 8Kib when used with --batch --gen-key.

* g10/gpg.c: Cleanup argument parsing.
--
c76117f8b0 mistakenly marked
compress-sigs and compress-keys as no-ops on the 2.0.x branch.
These options still have an effect on the 2.0.x branch, and the
duplicate declaration also causes the gpg argument parser to fail when
shortened versions of the option are present, like:
gpg: option "--compress-k" is ambiguous
* g10/gpg.c: Cleanup argument parsing.
--
With c76117f8b0, the GnuPG 2.0.x branch
accidentally introduced a second (identical) argument parser for both
--sk-comments, and for --no-sk-comments.
This caused short versions (e.g. omitting the trailing "s", as gpgme
does) of either command to fail with:
gpg: option "--sk-comment" is ambiguous
* g10/main.h (DEFAULT_DIGEST_ALGO): Use SHA256 in --gnupg and SHA1 in
strict RFC or PGP modes.
* g10/sign.c (make_keysig_packet): Use DEFAULT_DIGEST_ALGO also for
RSA key signatures.
--
(Backported from commit d332467005)
* g10/gpg.c: Add config options that should belong in scdaemon.conf
* g10/main.h, g10/misc.c (obsolete_scdaemon_option): New.
--
In gpg2, the following options are only relevant for scdaemon:
reader-port
ctapi-driver
pcsc-driver
disable-ccid
but in gpg1, they are options for gpg itself.
Some users of gpg1 might have these options in their
~/.gnupg/gpg.conf, which causes gpg2 to fail hard if it reads that
config file.
gpg2 should not fail hard, though giving a warning (and suggesting a
move to scdaemon.conf) seems OK.
This patch does *not* reintroduce any documentation for these options
in gpg.texi, even to indicate that they are "dummy" options, since
scdaemon.texi contains the appropriate documentation.

Program names factored out from obsolete_scdaemon_option to make

* g10/trustdb.c (clear_ownertrusts): Init trustdb.
--
This was fixed in 1.4 branch in commit
23191d7851 but was not applied to the
2.0 branch that exhibits the same problem. This is actually a hack
to fix a bug introduced with commit 2528178.

* g10/passphrase.c (passphrase_get): Replace sprintf by xasprintf.
--
Without that at least the French translation does not always work
because it requires positional parameters. Windows for example does
not support them as they are not defined by C99 but by POSIX.
* sm/gpgsm.h (opt): Add field "no_homedir_creation".
* sm/gpgsm.c (main): Set it if --no-options is used.
* sm/keydb.c: Include fcntl.h.
(try_make_homedir): New. Similar to the one from g10/openfile.c
(maybe_create_keybox): New. Similar to the one from g10/keydb.c.
(keydb_add_resource): Replace some code by maybe_create_keybox.
* g10/parse-packet.c (parse_attribute): Avoid xmalloc failure and cap
size of packet.
--
Tavis Ormandy reported a fatal error for attribute packets with a zero
length payload. This is due to a check in Libgcrypt's xmalloc which
rejects a malloc(0) instead of silently allocating 1 byte. The fix is
obvious.
In addition we cap the size of attribute packets similar to what we do
with user id packets. OpenPGP keys are not the proper way to store
movies.
Resolved conflicts:
g10/parse-packet.c - indentation. Use plain fprintf.

It was possible to create 16k RSA keys in batch mode. In addition to the
silliness of such keys, they have the major drawback that under GnuPG
and Libgcrypt, with their limited amount of specially secured memory
areas, the use of such keys may lead to an "out of secure memory"
condition.

This is a fix for commit 5e933008.
The old code did only work for a single key. It failed as soon as
several keys are specified ("gpg --refresh-keys" or "gpg --recv-key A
B C").

libgcrypt >= 1.6.

This is not anymore needed but kept for compatibility with Libgcrypt <
1.6.

Note that this is not a complete solution. The libgpg-error include
directory has now a higher preference but ld may not pick up the right
library if another one is installed. The problem is that the -L
option and the -l options are not emitted separately by
gpg-error-config.

INV_RECP.

(import_secret_one): Ditto.

(import_keys_stream): Ditto.
* g10/keyserver.c (keyserver_retrieval_filter): New.
(keyserver_spawn): Pass filter to import_keys_stream()
--
These changes introduces import functions that apply a constraining
filter to imported keys. These filters can verify the fingerprints of
the keys returned before importing them into the keyring, ensuring that
the keys fetched from the keyserver are in fact those selected by the
user beforehand.
