the allocated bit buffer in case the first zero bit was not within
size-1 first octets.

This makes it somewhat easier to use CONFIG_WPA_TRACE=y build with

requirement, e.g., when linking wpa_ctrl.c with a program that does not
use the os_*() wrappers.

If addition of a peer issuer certificate fails, the certs pointer would
be NULL when being passed to sk_X509_push() for peer issuer's issuer.
Fix this by skipping addition of issuer's issue if issuer addition
fails.

data.function needs to be set for the return value to be of any use and

In many applications it is useful not just to enumerate a group of well
known access points, but to use a address/mask notation to match an
entire set of addresses (ca:ff:ee:00:00:00/ff:ff:ff:00:00:00).
This change expands the data structures used by MAC lists to include a
mask indicating the significant (non-masked) portions of an address and
extends the list parser to recognize mask suffixes.

The new control interface command TEST_ALLOC_FAIL and GET_ALLOC_FAIL can
now be used to trigger memory allocation failures for testing purposes.
TEST_ALLOC_FAIL sets a failure conditions with
<count>:func[;func][;func]... string and GET_ALLOC_FAIL returns the
current state using the same format. Whenever an allocation is made with
a matching backtrace of calling functions, the count is decremented by
one and once zero is reached, the allocation is forced to fail.
Function names can be prefixed with either '=' or '?' to get different
matching behavior. '=' requires this specific function to be the next
one in the backtrace (i.e., do not skip any other functions in the list
which is the default behavior). '?' allows the function to be optionally
present in the backtrace.

With CONFIG_WPA_TRACE_BFD, the type cast from void* to integer was
generating a compiler warning due to the target integer being larger in
size in case of 32-bit builds. Type case to bfd_hostptr_t instead of
directly to bfd_vma to avoid this.

Shift right on unsigned char limits the value to 0..63 which is within

This allows the URL to be passed as a single argument to the program
instead of getting split into multiple by os_exec(). This makes the
operation more robust for cases where the URL could have been received
from an external source and could potentially add extra arguments to the
command line.
In addition, fix the /system/bin/input execution by using system() for
it instead of execv() through os_exec(). /system/bin/input is a script
that execv() won't be able to run. Since the full command line is
specified, system() can be used for this. The keycode is also changed
from 3 to KEYCODE_HOME to make this work with current Android version.
