* kbx/keybox-search.c (blob_get_keyid): Rename to
blob_get_first_keyid. Check number of keys and remove blob type check.
--
There is no need to check the blob type. We already know that it is a
key blob type and keyids are used for X.509 and OpenPGP. Also added
check for number of keys because the other parser functions do it as
well.

* kbx/keybox-search.c (blob_get_keyid): New.
(keybox-search): Call skipfnc callback function.
--
This patch (tentatively) fixes
GnuPG-bug-id: 1794
The keybox_search function in kbx/keybox-search.c currently ignores
the skipfnc callback, but the validate_key_list function in
g10/trustdb.c uses such a callback to exclude ultimately trusted keys.
* scd/pcsc-wrapper.c (handle_transmit): Enlarge buffer to 4096 too
allow for larger certificates.

* dirmngr/ks-engine-hkp.c (map_host): Fix error return.
--
In ks-engine-hkp.c on line 509 'reftbl' is freed, but it is then
used on line 511. I'm guessing this is a missing return;.

incorrectly closed using fclose.

* scd/command.c (cmd_readkey): avoid double-free of cert
--
When ksba_cert_new() fails, cert will be double-freed.
Debian-Bug-Id: 773471
Original patch changed by wk to do the free only at leave.
* common/iobuf.c: (iobuf_open): initialize len
--
In iobuf_open, IOBUFCTRL_DESC and IOBUFCTRL_INIT commands are invoked
(via file_filter()) on fcx, passing in a pointer to an uninitialized
len.
With these two commands, file_filter doesn't actually do anything with
the value of len, so there's no actual risk of use of uninitialized
memory in the code as it stands.
However, some static analysis tools might flag this situation with a
warning, and initializing the value doesn't hurt anything, so i think
this trivial cleanup is warranted.

* common/dotlock.c: (dotlock_create_unix) avoid double-close()
in unusual situations.
--
close(2) says:
close() should not be retried after an EINTR since this may
cause a reused descriptor from another thread to be closed.
Before this patch was applied, if close(fd) failed with EINTR, it
would be closed again in the write_failed: block.
It could also have been closed a second time in the case that
(use_hardlinks_p (h->tname)) evaluated to something other than 0 or 1.
This patch avoids both of those scenarios.
Note that close() could still be called twice on the same file
descriptor if the first close(fd) fails but errno is not EINTR. I'm
not sure the right thing to do in that scenario. An alternate
resolution could be to unequivocally set fd to -1 after the first
failed close(fd), avoiding the errno == EINTR test.

"Remove un-needed check. If 'url' were not to be true,

A remote connection is and should not be able to setup the local

fix is the same as used for ssh-agent connection: We use the default
environment as used at the startup of the agent.

Thanks.
This bug can't be exploited: Only if the announced length of the
notation is 21 or 32 a memcmp against fixed strings using that length
would be done. The compared data is followed by the actual signature
and thus it is highly likely that not even read of unallocated memory
will happen. Nevertheless such a bug needs to be fixed.
