5f65e9f717 nl80211: Abstract handling of sockets on eloop
Abstract the handling of sockets on the eloop to avoid
destroying sockets still on the eloop and also to allow
the next patch to mark the socket non-blocking.

e8d1168b73 nl80211: Register for IBSS auth frames before eloop
The IBSS code registers the bss nl_mgmt socket for auth
frames when the join event happens, but that is too late
as then the socket is already on the eloop, which could
cause problems when other events are received at the
same time as the registration is done.

Move the auth frame registration to the initial setup
before the socket is put onto the eloop.

03610ad28d Clean up get_seqnum() use for IPN
Some driver wrappers may implement this by writing eight octets even
though IPN is only six octets. Use a separate WPA_KEY_RSC_LEN (8) octet
buffer in the call to make sure there is enough buffer room available
for the full returned value and then copy it to IPN field.

The previous implementation used the following igtk field as the extra
buffer and then initialized that field afterwards, so this change does
not fix any real issue in behavior, but it is cleaner to use an explicit
buffer of the maximum length for get_seqnum().

f5eb9da304 nl80211: Clean up if_add() for hostapd use
The allocation of new_bss and its use was separated by a lot of code in
this function. This can be cleaned up by moving the allocation next to
the use, so that this all can be within a single #ifdef HOSTAPD block.
The i802_check_bridge() call was outside type == WPA_IF_AP_BSS case, but
in practice, it is only used for WPA_IF_AP_BSS (and if used for
something else, this would have resulted in NULL pointer dereference
anyway).

47d986e6ff P2P: Check Action frame payload match before accepted TX status
It is possible for there to be two pending off-channel TX frames, e.g.,
when two devices initiate GO Negotiation at more or less the same time.
This could result in the TX status report for the first frame clearing
wpa_s->pending_action_tx that included the newer frame that has not yet
been transmitted (i.e., is waiting to be sent out). Avoid losing that
frame by confirming that the TX status payload matches the pending frame
before clearing the pending frame and reporting the TX status callback.

d259249762 Fix ENABLE_NETWORK not to reconnect in disconnected state
DISCONNECT followed by ENABLE_NETWORK ended up starting a scan for a new
connection due to wpa_supplicant_enable_one_network() setting
wpa_s->reassociate = 1. This was done regardless of wpa_s->disconnected
being 1 which should imply that wpa_supplicant should not try to connect
before asked explicitly with REASSOCIATE or RECONNECT.

Fix this by making ENABLE_NETWORK setting of reassociate = 1 and
starting of scans for connection conditional on wpa_s->disconnected ==
0. This will make ENABLE_NETWORK trigger a connection only if
wpa_supplicant is already in a state where it would try to connect if
there are any enabled networks.
