The --suspend command can be used before a hibernate operation to make
the encrypted partition inaccessible and wipe the key from the memory.
Before --suspend is called a sync(1) should be run to make sure that
their are no dirty buffers (dmsetup, as called by g13, actually does
this for you but it does not harm to do it anyway. After the
partition has been suspended a
echo 3 >proc/sys/vm/drop_caches
required to flush all caches which may still have content from the
encrypted partition.
The --resume command reverses the effect of the suspend but to do this
it needs to decrypt again. Now, if the .gnupg directory lives on the
encrypted partition this will be problematic because due to the
suspend all processes accessing data on the encrypted partition will
be put into an uninterruptible sleep (ps(1) shows a state of 'D').
This needs to be avoided. A workaround is to have a separate GnuPG
home directory (say, "~/.gnupg-fallback") with only the public keys
required to decrypt the partition along with a properly setup
conf files. A
GNUPGHOME=$(pwd)/.gnupg-fallback g13 --resume
should then be able to resume the encrypted partition using the
private key stored on a smartcard.
The implementation is pretty basic right now but useful to me.

Before accessing pk->keyid, it is necessary to call keyid_from_pk (pk,
NULL) to ensure that pk->keyid is valid. Because it is easy to forget
to do this, these accessor functions take care of it.
* tools/gpgparsemail.c: Add and check info->signing_protocol_2.
--
Some mailers in the wild will generate messages that have the a weird
structure where they use the x- prefix in one part and drop it in
another.
For example, the main MIME part as a whole has:
Content-Type: multipart/signed;
protocol="application/x-pkcs7-signature"
but the signature sub-part has:
Content-Type: application/pkcs7-signature
(or vice versa, where the x- prefix is in the sub-part but not the
protocol= section on the main MIME object)
This change also avoids allocating strings for these comparisons,
since the const strings in question are already available in the built
executable, and no dynamic labels are needed.

* g10/keydb.h: Remove agent_open, agent_close declarations/
* g10/migrate.c: #include <unistd.h> for access()
--
agent_open() is only defined statically in common/simple-pw-query.c,
it is neither used nor referenced anywhere else. agent_close doesn't
exist anywhere. The removal of these declarations removes an
unecessary inclusion of libassuan.h.
migrate.c was relying on keydb.h -> libassuan.h -> unistd.h for the
declaration of access(), so we now handle that explicitly instead.
