Previously, during RSN preauthentication, ap_sta_bind_vlan() was called,
which fails for non-zero sta->vlan_id as the station is not known to the
kernel driver.
Fix this by binding the station only if it is associated. If it is not
associated, ap_sta_bind_vlan() will be done later during association.
In addition, reject Access-Accept if the returned VLAN ID is not valid
in the current hostapd configuration.

The dbus interface documentation says the following about the
WPS property of the fi.w1.wpa_supplicant1.BSS interface:
==
WPS information of the BSS. Empty dictionary indicates no WPS support.
Dictionary entries are:
Type s "pbc", "pin", ""
==
However the implementation returns "type" => "" for BSSes
that do not support WPS.
Fix the implementation to match the documentation.
Return empty dictionary if there is no WPS support.
And "type" => "" if WPS is supported, but is not in progress
right now.

Both Android's libc and glibc support _FORTIFY_SOURCE, a compiler
and libc feature which inserts automatic bounds checking into
common C functions such as memcpy() and strcpy(). If a buffer
overflow occurs when calling a hardened libc function, the
automatic bounds checking will safely shutdown the program and
prevent memory corruption.
Android is experimenting with _FORTIFY_SOURCE=3, a new fortify
level which enhances memcpy() to prevent overflowing an element
of a struct. Under the enhancements, code such as
struct foo {
char empty[0];
char one[1];
char a[10];
char b[10];
};
int main() {
foo myfoo;
int n = atoi("11");
memcpy(myfoo.a, "01234567890123456789", n);
return 0;
}
will cleanly crash when the memcpy() call is made.
Fixup hostap code to support the new level. Specifically:
* Fixup sha1_transform so it works with the enhanced bounds checking.
The old memcpy() code was attempting to write to context.h0, but that
structure element is too small and the write was extending (by design)
into h1, h2, h3, and h4. Use explicit assignments instead of
overflowing the struct element.
* Modify most of the structures in ieee802_11_defs.h to use ISO C99
flexible array members (https://gcc.gnu.org/onlinedocs/gcc/Zero-Length.html)
instead of a zero length array. Zero length arrays have zero length,
and any attempt to call memcpy() on such elements will always overflow.
Flexible array members have no such limitation. The only element not
adjusted is probe_req, since doing so will generate a compile time error,
and it's not obvious to me how to fix it.

It has been noticed that the band steering/load balancing of some
multi-AP networks will lead to an ever-growing list of blacklisted
BSSIDs. This eventually leads to a connection drop when the connection
is pushed to a distant AP.
Fix this issue by clearing the blacklist upon successful connect.

This function exposes internal state of the TLS negotiated parameters
for the sole purpose of being able to implement PRF for EAP-FAST. Since

cases, it is cleaner to keep this detail internal to each tls_*.c
wrapper implementation.

This is not needed anymore with the tls_connection_prf() being used to

tls_openssl.c is the only remaining TLS/crypto wrapper that needs the
internal PRF implementation for EAP-FAST (since
SSL_export_keying_material() is not available in older versions and does
not support server-random-before-client case). As such, it is cleaner to
assume that TLS libraries support tls_connection_prf() and move the
additional support code for the otherwise unsupported cases into
tls_openssl.c.

While that used to be the common case ten years ago, it is less common

The new network profile parameter mem_only_psk=1 can be used to specify
that the PSK/passphrase for that network is requested over the control
interface (ctrl_iface or D-Bus) similarly to the EAP network parameter
requests. The PSK/passphrase can then be configured temporarily in a way
that prevents it from getting stored to the configuration file.
For example:
Event:
CTRL-REQ-PSK_PASSPHRASE-0:PSK or passphrase needed for SSID test-wpa2-psk
Response:
CTRL-RSP-PSK_PASSPHRASE-0:"qwertyuiop"
Note: The response value uses the same encoding as the psk network
profile parameter, i.e., passphrase is within double quotation marks.
