This is not yet finished but a make check works. gpg has the most
complex and oldest option handling and thus this is the first
migration target. SE-Linux checks and version-ed config files are
missing and will be added later.

This cache speeds up processing of commands like "gpg -K" because
scdaemon does not need to be asked for each key as long as nothing
changed with the card.
We should have a better notification service from scdaemon to make
sure that we get only the relevant events. What we do right now is a

This change does away with encrypting and decrypting the cached PIN in
the agent. There is no need for this we can simply cache the
cryptogram and let scdaemon decrypt after retrieving it from the
agent. This way we do not need to share a key between gpg-agent and
scdaemon and further the cached content is invalid after the scdaemon
process has been replaced.

powerpc64, and sparc64 platforms.
There may well be other failures with %b on those platforms in the
codebase, and it probably needs an audit.
Once you have a key in private-keys-v1.d/$KEYGRIP.key with a comment

tested with:

A Label entry in the keyfile is always set manually and thus we can

--
If in the extended key format an item
Label: This is my key
is found, "This is my key" will be displayed instead of the comment
intially recorded in the s-expression. This is pretty useful for the
ssh keys because often there is only the original file name recorded
in the comment.
If no Label is found or it is empty the S-expression comment is used.
To show more than one line, the standard name-value syntax can be
used, for example:
Label: The Ssh key

<space>I registered on fencepost.

This has been tested with gpgsm and RSA keys. For ECC keys only
partly tested using the sample OpenPGP nistp256 and nistp384 keys
because gpgsm does not yet support ECC certificates and thus we can't
write the certificates to the cert object after a writekey. Note that
they nevertheless show up in "gpgcard list" because gpg-card searches
for them in gpg and gpgsm. However, this does not work completely.

* agent/call-pinentry.c (agent_popup_message_stop): Just kill it.
--
By checking if it's alive or not, we can lower a risk of sending

That's true, however, since it's alive usually, simply sending SIGINT
is enough here.
Note that here is a race condition for detecting if process is active
or not; A process can die just after being detected alive.
Moreover, when the process of pinentry accidentally died already, it
should have caused return of assuan_transact and the thread of
popup_message_thread likely already set popup_finished=1.

This fixes a potential overflow if LFs are passed to the status

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.

* dirmngr/dirmngr.c: Likewise.

* agent/gpg-agent.c (initialize_modules): Add hook again.
(main): Remove setting of the system houk but add scoket system hook
setting after assuan initialization.
--
Thread initialization is better to be deferred after fork (in case of
UNIX). assuan_sock_init should be earlier. Thus, we need to change
system hooks for assuan_sock_* interface. Or else, on Windows, it may
cause hang on server.

* agent/gpg-agent.c (initialize_modules): Move assuan_set_system_hooks.
(main): ... here, just before assuan_sock_init.
--
In Assuan, global variable SOCK_CTX is used internally, which is
initialized by assuan_sock_init. When initialized, system hooks
are copied into SOCK_CTX structure. Thus, system hooks should
be set, before the call of assuan_sock_init.

* common/logging.c: Do not build any code if we can use the gpgrt_log
functions.
(log_logv_with_prefix): Rename to log_logv_prefix and change order of
args so that this function matches its printf like counterpart
gpgrt_logv_prefix. Change all callers.
(log_debug_with_string): Rename to log_debug_string. Change all
callers.
(log_printhex): Move first arg to end so that this function matches
its printf like counterpart gpgrt_log_printhex. Change all callers.
* common/logging.h: Divert to gpgrt/libgpg-error if we can use the
gpgrt_log functions.
(bug_at): Add inline versions if we can use the gpgrt_log functions.
* configure.ac (GPGRT_ENABLE_LOG_MACROS): Add to AH_BOTTOM.
(mycflags): Add -Wno-format-zero-length.
--
This patch enables the use of the log function from libgpgrt (aka
libgpg-error). Instead of checking a version number, we enable them
depending on macros set by recent gpg-error versions. Eventually the
whole divert stuff can be removed.
The -Wno-format-zero-length is required because log_printhex can be
called with an empty format string. Note that this is fully specified
standard C behaviour.

* agent/gpg-agent.c (oAutoExpandSecmem): New enum value.
(opts): New option --auto-expand-secmem.
(main): Implement that option.
--
Note that this option has an effect only if Libgcrypt >= 1.8.2 is
used.

* agent/gpg-agent.c (handle_connections): Always check inotify fds.
--
I noticed a gpg-agent processed, probably in shutdown_pending state,
which was selecting on only these two inotify fds. The select
returned immediately but because we did not handle the fds in
shutdown_pending state they were not read and the next select call
returned one of them immediately again. Actually that should not
hanppen because the
if (active_connections == 0)
break; /* ready */
should have terminated the loop. For unknown reasons (maybe be just a
connection thread terminated in a gdb session) that did not happen.
By moving the check outside of the shutdown_pending condition and
closing the fd after they have been triggered the code should be more
robust.
