The error reply needs to be sent out as a response. The "out" label was
in incorrect place to allow that to happen; instead, it ended up leaking
memory for the generated reply message.

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.

The per-BSS configuration information needs to be freed if hostapd fails

If hostapd_alloc_bss_data() failed to allocate the struct hostapd_data
instance, dynamic interface addition path ended up trying to dereference
freed memory due to incorrect cleanup steps. Fix this by decrementing
the interface count when the newly added interface is removed. In
addition, make the setup more robust by clearing all changes within
hostapd_data_alloc() if any of the allocations fails.

Unfortunately, libnl 3.0 has changed the API in a way that is not
backwards compatible by renaming nlmsg_len() to nlmsg_datalen() without
leaving the older nlmsg_len() defined. As such, there does not seem to
be any clean way of using this function without breaking the build with
some libnl versions. For now, replace this call with direct calculation
of the data length since it can be done with a simple one-liner that
compiles with all libnl versions.

These are practically unreachable code since cfg80211 fills in the
required attributes or does not send the event. Keep the checks in
place, but minimize the extra code in wpa_supplicant/hostapd.

cfg80211 dropped support for tracking BSS authentication state and
setting NL80211_BSS_STATUS_AUTHENTICATED in 'cfg80211: stop tracking
authenticated state' three years ago (starting in Linux 3.4). As such,
this workaround code in wpa_supplicant cannot be reached anymore. There
is no real need for maintaining it for older kernels either, since there
are other ways of detecting and working around state mismatches with the
actual authentication operations failing.

While there is no explicit driver capability advertisement for this in
nl80211, the EOPNOTSUPP response can be interpreted as a clear
indication of NL80211_CMD_SET_REKEY_OFFLOAD not being supported. Check
for that and don't try to offload keys again if the driver has not use
for them.

The supplicant code does not try to control the actual channel of the
radio at any point. It simply passes the target peer and channel

periodically initiate TDLS channel-switch operations when TDLS
channel-switching is enabled.
