What we do here is to keep track of key searches by long keyids (as

again after we already found that this keyid will result in
not-found. As soon as we change gpg to run as a co-process we should
store this table per session because other instances of gpg may have
updated the keybox without us knowing.

Note that although PKA is now always build, it will only work if

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.

Reported-by: Guilhem Moulin <guilhem@fripost.org>
Needed for unattended key edits with --status-fd, because since 2.1
status prompts are preceded by es_fflush (in cpr.c:do_get_from_fd)
not fflush(3), so the standard output may not be flushed before each
prompt. (Which breaks scripts using select(2) to multiplex between
the standard and status outputs.)
His patch only affected print_and_check_one_sig_colon() but there are
many more places where stdio and estream are mixed. This patch now
replaces most of them in g10/. At some places stdio is still used,
but that is local to a function and should not have side effects.

* g10/keyring.c (keyring_get_keyblock): Whitelist allowed packet

* g10/keydb.c (parse_keyblock_image): Ditto.
--
The keyring DB code did not reject packets which don't belong into a
keyring. If for example the keyblock contains a literal data packet
it is expected that the processing code stops at the data packet and
reads from the input stream which is referenced from the data packets.
Obviously the keyring processing code does not and cannot do that.
However, when exporting this messes up the IOBUF and leads to an
invalid read of sizeof (int).
We now skip all packets which are not allowed in a keyring.

Without that it is possible to force gpg to allocate large amounts of
memory by using a bad encoded MPI. This would be an too easy DoS.
Another way to mitigate would be to change the MPI read function to
allocate memory dynamically while reading the MPI. However, that
complicates and possibly slows down the code. A too large key packet
is in any case a sign for broken data and thus gpg should not use it.

This bug can't be exploited: Only if the announced length of the

and thus it is highly likely that not even read of unallocated memory

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.

gnulib has always been a cause of trouble in GnuPG because we used

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.

v3 keys are deprecated for about 15 years and due the severe
weaknesses of MD5 it does not make any sense to keep code around to
use these old and broken keys. Users who need to decrypt old messages
should use gpg 1.4 and best re-encrypt them to modern standards.
verification of old (i.e. PGP2) created signatures is thus also not
anymore possible but such signatures have no values anyway - MD5 is
just too broken.
We have also kept support for v3 signatures until now. With the
removal of support for v3 keys it is questionable whether it makes any
sense to keep support for v3-signatures. What we do now is to keep
support for verification of v3-signatures but we force the use of
v4-signatures. The latter makes the --pgp6 and --pgp7 switch a bit
obsolete because those PGP versions require v3-signatures for
messages. These versions of PGP are also really old and not anymore
maintained so they have not received any bug fixes and should not be
used anyway.

This is a cherry-pick of 534e2876acc05f9f8d9b54c18511fe768d77dfb5 from
STABLE-BRANCH-1-4 against master
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.

The problem was reported by dkg on gnupg-devel (2014-10-07):
I just discovered a new problem, though, which will affect people on
systems that have gpg and gpg2 coinstalled:
0) create a new keyring with gpg2, and use it exclusively with gpg2
for a while.
1) somehow (accidentally?) use gpg (1.4.x) again -- this creates
~/.gnupg/pubring.gpg
2) future runs of gpg2 now only look at pubring.gpg and ignore
pubring.kbx -- the keys you had accumulated in the keybox are no
longer listed in the output of gpg2 --list-keys
Note that gpgsm has always used pubring.kbx and thus this file might
already be there but without gpg ever inserted a key. The new flag in
the KBX header gives us an indication whether a KBX file has ever been
written by gpg >= 2.1. If that is the case we will use it instead of
the default pubring.gpg.

In the course of building GnuPG 2.1.0 beta864 on debian, i found that
several of the installed executables were linked to libraries that
they did not need to be linked to, which would cause unnecessary
package dependencies at runtime.
The changeset here removes these unnecessary libraries from linking.
Something similar could possibly also be done by passing --as-needed
to the linker, but trimming the depenencies seems more parsimonious.

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.

This patch adds two features:
1. The key for the last passphrase successfully used for unprotecting
a key is stored away. On a cache miss the stored away passphrase is
tried as well. This helps for the common GPG use case of having a
signing and encryption (sub)key with the same passphrase. See the
code for more comments.
2. The now auto-generated revocation certificate does not anymore
popup a passphrase prompt. Thus for standard key generation the
passphrase needs to be given only once (well, two with the
confirmation).

These changes introduces import functions that apply a constraining

A packet like (a3 01 5b ff) leads to an infinite loop. Using

Actually it would be sufficient to stuff just one extra 0xff byte.
Given that this problem popped up only after 15 years, I feel safer to
allow for a very few FF bytes.

we better make sure that secret keys are never received from remote

For ECC it seems to be better to show the name of the curve and not
just the size of the prime field. The curve name does not anymore fit
into the "<size><letter>" descriptor (e.g. "2048R") and a fixed length
format does not work either. Thus the new format uses
"rsa2048" - RSA with 2048 bit
"elg1024" - Elgamal with 1024 bit
"ed25519" - ECC using the curve Ed25519.
"E_1.2.3.4" - ECC using the unsupported curve with OID "1.2.3.4".
unless --legacy-list-mode is given. In does not anymore line up
nicely in columns thus I expect further changes to this new format.

This patch separates Libgcrypt and OpenPGP public key algorithms ids
and in most cases completely removes the Libgcrypt ones. This is
useful because for Libgcrypt we specify the algorithm in the
S-expressions and the public key ids are not anymore needed.
This patch also adds some support for PUBKEY_ALGO_EDDSA which will
eventually be used instead of merging EdDSA with ECDSA. As of now an
experimental algorithm id is used but the plan is to write an I-D so
that we can get a new id from the IETF. Note that EdDSA (Ed25519)
does not yet work and that more changes are required.
The ECC support is still broken right now. Needs to be fixed.

--
With the gpg-agent taking care of the secret keys, the user needs to
migrate existing keys from secring.gpg to the agent. This and also
the standard import of secret keys required the user to unprotect the
secret keys first, so that gpg-agent was able to re-protected them
using its own scheme. With many secret keys this is quite some
usability hurdle. In particular if a passphrase is not instantly
available.
To make this migration smoother, this patch implements an unattended
key import/migration which delays the conversion to the gpg-agent
format until the key is actually used. For example:
gpg2 --batch --import mysecretkey.gpg
works without any user interaction due to the use of --batch. Now if
a key is used (e.g. "gpg2 -su USERID_FROM_MYSECRETKEY foo"), gpg-agent
has to ask for the passphrase anyway, converts the key from the
openpgp format to the internal format, signs, re-encrypts the key and
tries to store it in the gpg-agent format to the disk. The next time,
the internal format of the key is used.
This patch has only been tested with the old demo keys, more tests
with other protection formats and no protection are needed.

(passphrase_to_dek_ext): Factor some code out to ...
(emit_status_need_passphrase): new.
* g10/call-agent.c (start_agent): Send the pinentry mode.
(default_inq_cb): Take care of the PASSPHRASE inquiry. Return a
proper error code.
(agent_pksign): Add args keyid, mainkeyid and pubkey_algo.
(agent_pkdecrypt): Ditto.
* g10/pubkey-enc.c (get_it): Pass new args.
* g10/sign.c (do_sign): Pass new args.
* g10/call-agent.c (struct default_inq_parm_s): New. Change all
similar structs to reference this one. Change all users and inquire
callback to use this struct, instead of NULL or some undefined but not
used structs. This change will help to eventually get rid of global
variables.

This new features allows to use gpg without a Pinentry. As a
prerequisite the agent must be configured to allow the loopback
pinentry mode (option --allow-loopback-pinentry). For example
gpg2 --pinentry-mode=loopback FILE.gpg
may be used to decrypt FILE.gpg while entering the passphrase on the
tty. If batch is used, --passphrase et al. may be used, if
--command-fd is used, the passphrase may be provided by another
process. Note that there are no try-again prompts in case of a bad
passphrase.
* common/iobuf.c (iobuf_seek): Fix for temp streams.
* g10/pubkey-enc.c (get_session_key, get_it): Add some log_clock calls.
* g10/keydb.c (dump_search_desc): New.
(enum_keyblock_states, struct keyblock_cache): New.
(keyblock_cache_clear): New.
(keydb_get_keyblock, keydb_search): Implement a keyblock cache.
(keydb_update_keyblock, keydb_insert_keyblock, keydb_delete_keyblock)
(keydb_rebuild_caches, keydb_search_reset): Clear the cache.

Gpg uses the key database at several places without a central
coordination. This leads to several scans of the keybox for the same
key. To improve that we now use a simple cache to store a retrieved
keyblock in certain cases. In theory this caching could also be done
for old keyrings, but it is a bit more work and questionable whether
it is needed; the keybox scheme is anyway much faster than keyrings.
Using a keybox with 20000 384 bit ECDSA/ECHD keypairs and a 252 byte
sample text we get these values for encrypt and decrypt operations on
an Core i5 4*3.33Ghz system. The option --trust-model=always is used.
Times are given in milliseconds wall time.
| | enc | dec | dec,q |
|-----------+-----+-----+-------|
| key 1 | 48 | 96 | 70 |
| key 10000 | 60 | 98 | 80 |
| key 20000 | 69 | 106 | 88 |
| 10 keys | 540 | 290 | 70 |
The 10 keys test uses a mix of keys, the first one is used for
decryption but all keys are looked up so that information about are
printed. The last column gives decryption results w/o information
printing (--quiet).
The keybox is always scanned sequentially without using any index. By
adding an index to the keybox it will be possible to further reduce
the time required for keys stored to the end of the file.
