* dirmngr/ks-engine-hkp.c (handle_send_request_error): Handle two more
error codes.
--
Handle the two possible connect failures related to missing IPv6 support
gracefully by marking the host dead and retrying with another one.
If IPv6 is disabled via procfs, connect() will return EADDRNOTAVAIL.
If IPv6 is not compiled into the kernel, it will return EAFNOSUPPORT.
This makes it possible to use dual-stack hkp servers on hosts not having
IPv6 without random connection failures.

The above description seems to be for Linux, so it is possible that
other systems might behave different. However, it is worth to try
this patch.

log_error for skipped packets.

log_info should be sufficient and makes this more robust. Some
tools (e.g. Enigmail) are too picky on return codes from gpg.

This can be used to build GnuPG with static versions of the core
gnupg libraries. For example:
make -f build-aux/speedo.mk STATIC=1 SELFCHECK=0 \
INSTALL_PREFIX=/somewhere/gnupg22 native
The SELFCHECK=0 is only needed to build from a non-released version.
You don't need it with a released tarball.

On most 32 bit systems size_t is 32 bit and thus the check
size_t cert_off = get32 (buffer+8);
size_t cert_len = get32 (buffer+12);
if (cert_off+cert_len > length)
return gpg_error (GPG_ERR_TOO_SHORT);
does not work as intended for all supplied values. The simplest
solution here is to cast them to 64 bit.
In general it will be better to avoid size_t at all and work with
uint64_t. We did not do this in the past because uint64_t was not
universally available.

This bug is not serious but makes some consistency checks fail.
For example, 'openssl rsa -check' reports the following error:
$ gpgsm --out my.key --export-secret-key-raw 0xXXXXXXXX

RSA key error: dmq1 not congruent to d

Let me(wk) add this:
This bug was introduced with
Fixes-commit: 91056b1976
right at the start of GnuPG 2.1 in July 2010. Before that (in 2.0) we
used gpg-protect-tool which got it right. We probably never noticed
this because gpgsm, and maybe other tools too, fix things up during
import.

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.

* scd/app-openpgp.c (get_cached_data): Return NULL for Data Object
with no data.
--
When GET_DATA returns no data with success (90 00), this routine
firstly returned buffer with length zero, and secondly (with cache)
returned NULL, which is inconsistent. Now, it returns NULL for both
cases.

I did some test to see whether this has an effect. A test program
piped 100 million random bytes to gpg to symmetric encryption only w/0
compression. Single read means the old behaviour, multi read the new
behaviour which fills up the buffer when the read(2) returned only 4k
in once call.
