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.

NIIBE Yutaka f8b8b6aac2 scd: Fix status check when using PC/SC.
* scd/apdu.c (struct reader_table_s): Add field of current_state.

(pcsc_get_status): Keep the status in READER_TABLE array.

* scd/scdaemon.c (handle_connections): Silence a warning.

--

To detect some change of card status, including suspend/resume
possibly, SCardGetStatusChange should be used keeping the
dwCurrentState field.

This change could improve situation for suspend/resume with Yubikey on
Windows.  Even not, this is doing the Right Thing.

* scd/command.c (send_status_info): Bump up N.
--

This fixes a potential overflow if LFs are passed to the status
string functions.  This is actually not the case and would be wrong
because neither the truncating in libassuan or our escaping is not the
Right Thing.  In any case the functions need to be more robust and
comply to the promised interface.  Thus the code has been factored out
to a helper function and N has been bumped up correctly and checked in
all cases.

For some uses this changes the behaviour in the error case (i.e. CR or
LF passed): It will now always be C-escaped and not passed to
libassuan which would truncate the line at the first LF.

When GET_DATA returns no data with success (90 00), this routine

--

We can use the interrupt transfer to be notified about card status
change.  In this case, we don't need to issue PC_to_RDR_GetSlotStatus
command.  This change improve the setup the notification; it should be
done after registration of APP.

When the setup is done just after opening the USB connection (before
issuing PC_to_RDR_IccPowerOn), a reader might notifies about no card
availability (because of not yet powered on), even though the card is
ready to be powered on.

Co-authored-by: Arnaud Fontaine <arnaud.fontaine@ssi.gouv.fr>

Arnaud wrote:

  Actually, when the incorrect expected response length (i.e. Le
  field) is transmitted to the card, the card's answer is missing a
  byte (i.e. ...  6101) so an additional command has to be sent to the
  card to retrieve the last byte. Using the correct length avoids to
  send the additional command to retrieve the missing byte, when the
  computed length is wrong.

Note that an value of 65537 for E is pretty standard and thus we can
avoid the 6101 return code inmost cases.

This bug is difficult to reproduce because the probability is 1/256,

Reproducible scenario: Invoke gpg --card-edit session from a terminal.
Invoke another gpg --card-edit session from another.  Remove a token.
Insert a token again.  Type RET on both terminals.  One of terminal
answers "Conflicting usage".

Perhaps, having NO_REUSE field was to avoid race conditions.  Now,
APP can be safely deallocated by application_notify_card_reset.

NIIBE Yutaka 01a2a61bc4 scd: PC/SC reader selection by partial string match.
* scd/apdu.c (open_pcsc_reader_direct): Partial string match.

--

The card reader name by PC/SC service might include USB bus,
which varies (on some platform like GNU/Linux).  Thus, it's
better to match partial string.

Original patch was submitted by anstein.  I changed it to fallback to
the first reader if no match found.

Note that we need to change pcsc-wrapper.c in 2.0 backport.

gnulib has always been a cause of trouble in GnuPG because we used
only a very few functions and the complex include machinery of gnulib
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.

In part two we will address the functions

 mkdtemp
 setenv
 unsetenv
 strpbrk

which may bot be implemented on all platforms.  They are not required
on a libc based system.
