The previous roam() and roam_over_ds() checks would have ignored failing
association rejection if a consecutive attempt to connect succeeds
within the initial time limit. This can miss incorrect behavior, so
check explicitly for association rejection.

During P2PS PD Request processing wpa_supplicant removes stale
persistent groups, but it did not notify D-Bus to unregister object.
This can result in leaving behind objects pointing to freed memory and
memory leaks. Sometime it can cause a crash in wpa_config_get_all()
function and DBUS_ERROR_OBJECT_PATH_IN_USE errors.
Fix this by adding the missed notification to D-Bus code to unregister
the object.

RSN initialization should work together with mesh join when it's used.
Since mesh join could be called at a different stage if DFS channel is
used, relocate the RSN initialization call to mesh join. It is still the
same call flow of mesh join before this if non-DFS channels are used,
hence no significant side effect will occur.

Mesh join function consists of two parts which are preparing
configurations and sending join event to the driver. Since physical mesh
join event could happen either right after mesh configuration is done or
after CAC is done in case of DFS channel is used, factor out the

The documentation in the hostapd.conf file says that the dynamic_vlan
variable is used to control whether VLAN assignments are accepted from a
RADIUS server. The implication seems to be that a static VLAN assignment
will come from the accept_mac_file if dynamic_vlan is set to 0, and a
dynamic assignment will come from the RADIUS server if dynamic_vlan is
set to 1. Instead, I'm seeing that the static settings from the
accept_mac_file are ignored if dynamic_vlan is set to 0, but used if
dynamic_vlan is set to 1. If dynamic_vlan is set to 1 and the RADIUS
server does not provide a VLAN, then the accept_mac_file assignment is
overridden and the STA is assigned to the default non-VLANed interface.
If my understanding of the expected behavior is correct, then I believe
the problem is in ap_sta_set_vlan(). That routine checks the
dynamic_vlan setting, but has no way of determining whether the incoming
vlan_desc is static (i.e., from accept_mac_file) or dynamic (i.e., from
a RADIUS server).
I've attached a patch that gets hostapd working as I believe it's meant
to, and updates the documentation to make the implicit behavior
explicit.
The functional changes are:
- hostapd_allowed_address() will always extract the vlan_id from the
accept_macs file. It will not update the vlan_id from the RADIUS cache
if dynamic_vlan is DISABLED.
- hostapd_acl_recv_radius() will not update the cached vlan_id if
dynamic_vlan is DISABLED.
- ieee802_1x_receive_auth() will not update the vlan_id if dynamic_vlan
is DISABLED.
More cosmetic:
Most of the delta is just moving code out of ieee802_1x_receive_auth()
into a new ieee802_1x_update_vlan() routine. While I initially did this
because the new DISABLED check introduced excessive indentation, it has
the added advantage of eliminating the vlan_description allocation and
os_memset() call for all DYNAMIC_VLAN_DISABLED configs.
I've done a couple rounds of review offline with Michael Braun (who has
done much of the work in this part of the code) and incorporated his
feedback.
If dynamic_vlan=0 (disabled), vlan assignments will be managed using the
local accept_mac_file ACL file, even if a RADIUS server is being used
for user authentication. This allows us to manage users and devices
independently.

When the frame body subelement would cause the measurement report
element to exceed the maximum element size, the frame body subelement
used to be truncated. In addition, some elements were always truncated
in order to keep the reported frame body short (e.g. RSN IE).
Alternatively, IEEE P802.11-REVmd/D2.0, 9.4.2.21.7 extension to Beacon
reporting can be used: The frame body subelement is fragmented across
multiple beacon report elements, and the reported frame body fragment ID
subelement is added.
Use beacon report fragmentation instead of truncating the frame body
as this method gives the AP a more complete information about the
reported APs.

According to random(4) manual, /dev/random is essentially deprecated on
Linux for quite some time:
"The /dev/random interface is considered a legacy interface, and
/dev/urandom is preferred and sufficient in all use cases, with the
exception of applications which require randomness during early boot
time; for these applications, getrandom(2) must be used instead, because
it will block until the entropy pool is initialized."
An attempt to use it would cause unnecessary blocking on machines
without a good hwrng even when it shouldn't be needed. Since Linux 3.17,
a getrandom(2) call is available that will block only until the
randomness pool has been seeded.
It is probably not a good default yet as it requires a fairly recent
kernel and glibc (3.17 and 2.25 respectively).
