The only time the PIN should fail is when we initialize the TLS
connection, so it doesn't really make sense to get rid of the PIN just
because some other part of the handshake failed.
This is a followup to commit fd4fb28179
('OpenSSL: Try to ensure we don't throw away the PIN unnecessarily').

with ubsan functinality from the recent gcc/clang compiler versions.

The IPv4 header after the Ethernet header is not 32-bit aligned and the
previous version ended up accessing 32-bit members at misaligned
addresses.

The IPv6 address in the frame buffer may not be 32-bit aligned, so use a
local copy to align this before reading the address with 32-bit reads
(s6_addr32[]).

64-bit builds with CONFIG_WPA_TRACE=y resulted in the wpabuf pointers
getting misaligned (only 32-bit aligned) and that would result in reads
and writes of unaligned size_t values. Avoid this by indicating explicit
alignment requirement for wpabuf_trace to 8 octets (i.e., there will be
extra four octets of padding in case of 64-bit builds).
Similarly, struct os_alloc_trace resulted in some potential misalignment
cases, e.g., when CONFIG_ACS=y uses a 'long double' variable within
struct hostapd_channel_data. Avoid misalignment issues with explicit
alignment indication.

src/utils/list.h ended up defining a local version of offsetof() due to
stddef.h not getting included. This resulted in unnecessary warnings
from ubsan related to "dereferencing" of a NULL pointer.

The input parameter ended up being converted to long int instead of int,
so use an explicit typecase to get rid of the compiler warning.

Use explicit typecasting to avoid implicit conversion warnings in cases
where enum eap_erp_type is used in functions taking an EapType argument.

Commit 38279bdb35 ('D-Bus: Coding style
cleanup') handled the dbus_new_handlers.c change properly, but misplaced
the second 'const' in dbus_old_handlers.c in a way that resulted in
duplicated const rather than marking the actual value const.

The FT-specific check for valid group cipher in wpa_ft_gen_req_ies() was
not up-to-date with the current list of supported ciphers. Fix this by
using a generic function to determine validity of the cipher. In
practice, this adds support for using CCMP-256 and GCMP-256 as the group
cipher with FT.

The new TEST_FAIL and GET_FAIL control interface commands can be used
similarly to the earlier TEST_ALLOC_FAIL/GET_ALLOC_FAIL design. The new
version is more generic framework allowing any function to be annotated
for failure testing with the TEST_FAIL() macro. This mechanism is only
available in builds with CONFIG_WPA_TRACE_BFD=y and
CONFIG_TESTING_OPTIONS=y. For other builds, the TEST_FAIL() macro is
defined to return 0 to allow the compiler to remove the test code from
normal production builds.
As the first test site, allow os_get_random() to be marked for failing
based on call backtrace.

Do not allow 40 MHz co-ex PRI/SEC switch to force us to change our PRI
channel if we have an existing connection on the selected PRI channel
since doing multi-channel concurrency is likely to cause more harm than
using different PRI/SEC selection in environment with multiple BSSes on
these two channels with mixed 20 MHz or PRI channel selection.

Fix a condition when Advertised Service Info Attribute is added to
a probe response in p2p_buf_add_service_instance(). The issue is
that a 'found' value is increased even if 'test' and 'adv->hash' hashes
are different. As result 'found' may have a non-zero value when an
attribute data length is 0. In this cause an empty attribute is about to
be added. Fixing it by eliminating 'found' and checking 'total_len'
containing a real number of bytes added to Advertised Service Info
Attribute.
This fixes an issue from commit 50a9efe713
('P2PS: Fix Probe Response frame building in error cases').

In p2p_find command line processing a loop searching for multiple
'seek=' parameters modifies cmd buffer adding '\0' terminators.
The 'freq=' parameter is handled after that and can be
lost if a 'freq=' follows 'seek=' in a command line.
Fix it by moving a handling of 'freq=' parameter to be processed
before 'seek=' handling loop.

The current P802.11 description of SAE uses "1 < element < p" as the
required range. However, this is not correct and does not match the
Dragonfly description of "1 < element < p-1". SAE definition will need
to change here. Update the implementation to reject p-1 based on the
correct rule here.
