68a866974b D-Bus (old): Fix wpsReg error message
This was supposed to return WpsRegError, not WpsPbcError.

f0614bc6c6 D-Bus (old): Fix message handler error paths
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.

3d2e2d5d63 trace: Fix compiler warning on 32-bit builds with bfd support
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.

e10422c025 Fix memory leak on hostapd BSS addition error path

2801659268 Fix hostapd initialization error path on allocation failure
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.

d58ade2121 nl80211: Fix compilation with libnl 1.1 and 2.0
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.

38751d8bd5 nl80211: Remove cfg80211 state mismatch workaround for authentication
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.

730a0d16bf nl80211: Always register management frames handler
If registering WMM-AC ADDTS response action frame or WMM-AC DELTS
action frame fails, the management frame handler is not being
registered. This results with a segmentation fault when trying to
unsubscribe the handler when the interface is removed.
Fix it by always registering the handler and just returning a negative
value to note that the action frame could not be registered.

This fixes an issue introduced in the commit
dfa8787833 ('nl80211: Implement
add_ts/del_ts ops').
