Daniel Kahn Gillmor 381c46818f agent: unknown flags on ssh signing requests cause an error.
* agent/command-ssh.c (ssh_handler_sign_request): if a flag is passed
during an signature request that we do not know how to apply, return
GPG_ERR_UNKNOWN_OPTION.

--

https://tools.ietf.org/html/draft-miller-ssh-agent-02#section-4.5 says:

    If the agent does not support the requested flags, or is otherwise
    unable or unwilling to generate the signature (e.g. because it
    doesn't have the specified key, or the user refused confirmation of a
    constrained key), it must reply with a SSH_AGENT_FAILURE message.

gpg,w32: Fix empty homedir when only a drive letter is used.
* common/homedir.c (copy_dir_with_fixup): New.
(default_homedir): Use here.
(gnupg_set_homedir): And here .
--

This actually fixes a couple of cases for Windows.  Both --home-dir
and GNUPGHOME.  The interpretation of "c:" -> "c:/" might not be the
correct one but because we need an absolute dir anyway it is the less
surprising one.  Note that this does not include a full syntax check
and fixup and thus it is very well possible that the result is not an
absolute directory.

When gpg-agent detects homedir removal, it will automatically exit.
Then, call of 'gpgconf --kill all' will fail.  So, stop-agent should
be called before the removal of homedir.

NIIBE Yutaka 2969271876 scd: Support changing key attribute back to RSA.
* scd/app-openpgp.c (change_rsa_keyattr): Try usual RSA.

--

In the OpenPGP card specification, there are multiple options to
support RSA (having P and Q or not, etc.), and it is implementation
dependent.  Since GnuPG doesn't have knowledge which card
implementation support which option and there is no way (yet) for card
to express itself which key attributes are supported, we haven't
supported key attribute change back to RSA.  But, many card
implementation uses P and Q, try this option.  If other cases,
factory-reset would be easier option.

Changing key attribute resets PIN authentication status.  So, CHECKPIN

* g10/tdbio.c (is_locked): Turn into a counter.
(take_write_lock, release_write_lock): Implement recursive locks.
--

On trustdb creation we have this call sequence:

  init_trustdb                 -> takes lock
    tdbio_set_dbname
      create_version_record
       tdbio_write_record
         put_record_into_cache -> takes lock
         put_record_into_cache -> releases lock
  init_trustdb                 -> releases lock

The second take lock does noting but the first release lock has
already released the lock and the second release lock is a thus a NOP.
This is likely the cause for the corrupted trustdb as reported in

If the final subpacket has only a length header evaluating to zero and

Valgrind detected this.  Fix is obvious.  Note that the further
parsing of the subpacket is still okay because it always checks the
length.  Note further that --list-packets uses a different code path
and already reported an error.

NIIBE Yutaka 71e5282c25 scd: Fix for GNU/Linux suspend/resume.
* configure.ac (require_pipe_to_unblock_pselect): Default is "yes".
* scd/scdaemon.c (scd_kick_the_loop): Minor clean up.

Normally SIGCONT or SIGUSR2 works for unblocking pselect.  But on my
machine with GNU/Linux, when a machine is suspend/resume-ed, pselect
keeps blocked, while signal itself is delivered.

It's better to use pipe.
