e55f98f4b8 Disable AP PIN on all interfaces controlled by the same process

disable AP PIN on all interfaces if an attack is detected on any
interface.

9290cc1800 Apply hostapd WPS commands to all interfaces on concurrent APs
When the same hostapd process is controlling multiple interfaces,

interfaces that are configured to use WPS.

01cf713e51 Fix .gitignore files to not ignore subdirectory matches
The previous used .gitignore files were mathing some files that
were actually already in the repository (e.g.,
hostapd/logwatch/hostapd). Avoid this by listing the conflicting
entries in the root directory .gitignore with full path.

bf0ed63f3f Allow a postfix to be defined for the version number
A separate build number (etc.) version number postfix can now be
added to the build without having to modify source code files by
defining VERSION_STR_POSTFIX. This can be done, e.g., by adding
following line to .config:

CFLAGS += -DVERSION_STR_POSTFIX=\"-foo\"

0314e26a61 Fix wpa_supplicant AP mode with WPS not to crash
Commit 3379a3a795 added a direct
iface->for_each_interface use without verification whether the
function is available. This works with hostapd, but not
wpa_supplicant (which crashes on segfault).

416192628d Fix AP mode 40 MHz pri/sec channel parsing in overlap determination
The previous implementation ended up incorrectly assuming that all
40 MHz use cases have secondary channel above the primary one. Fix this
by properly masking the secondary channel offset field and checking its
value.

32f4e7b124 wext: Fix scan result signal levels when driver reports in dBm
wpa_supplicant showed signal levels incorrectly with some drivers:
Jun  6 16:29:36 rupert wpa_supplicant[18945]: Current BSS: 00:0d:97:11:40:d6
level=190
Jun  6 16:29:36 rupert wpa_supplicant[18945]: Selected BSS: 00:0d:97:11:50:09
level=192

Judging from output from other tools (iwlist) and the min_diff block
at the end of wpa_supplicant_need_to_roam, it seems these values
should actually be negative. Specifically, if one treats that number
as a signed char instead of unsigned, everything matches up.

To be honest, I've little to no understanding of wireless, but looking
at the source code for wireless-tools (iw_print_stats in iwlib.c), it
seems that the fields of the iw_quality struct need to be decoded
differently depending on various flags. I guess
src/drivers/driver_wext.c should have similar logic in
wext_get_scan_qual.

I wrote a patch that attempts to replicate some of that logic,
although it may be more complicated than is necessary; I think some of
the complexity is for backwards-compatibility, which might not be
necessary depending on wpa_supplicant's dependencies? In any case, it
is attached. Again, I don't know how any of this works, so it's likely
the patch is a bit off. But I think at least the logic to determine
min_diff in wpa_supplicant_need_to_roam would be more accurate if
level were determined correctly.

a9d69254e3 WPS ER: Make sure PIN timeout does not interrupt PBC operation
We need to clear the selected registrar timeout from wps_er_learn
when stopping the protocol run at M7 (previously, this was done only
when WSC_Done was being processed). In addition, we need to cancel
the timeout when a new PBC operation is started.

fa37511fa7 WPS: Fix hostapd reconfig to update WPS UPnP string pointers
This is needed to update the pointers maintained within WPS code
to use the new configuration data instead of maintaining pointers
to the old configuration which will be freed. This fixes strings in
UPnP discovery after reconfig (they used to be random freed memory..).

70153d385c hostapd: Add virt/phy flag for Display/PushButton if needed (WPS 2.0)
This seems to be the easiest way of making sure the Config Methods
value is compliant with the WSC 2.0 specification without having
to modify the configuration file. However, this will only add the
virtual flag, so the configuration files should really be updated
to specify values that match the AP design.

0e2e565a44 WPS 2.0: Provide (Re)Association Response WPS IE to driver
WPS 2.0 mandates the AP to include WPS IE in (Re)Association Response
if the matching (Re)Association Request included WPS IE. Provide the
needed WPS IE information to the driver_ops API for drivers that
process association frames internally.

Note: This modifies the driver_ops API by adding a new argument to
set_ap_wps_ie().

b4e34f2fdf WPS: Make testing operations configurable at runtime
Instead of build time options (CONFIG_WPS_TESTING_EXTRA_CRED and
CONFIG_WPS_EXTENSIBILITY_TESTING), use a single build option
(CONFIG_WPS_TESTING) and runtime configuration of which testing
operations are enabled. This allows a single binary to be used
for various tests.

The runtime configuration can be done through control interface
with wpa_cli/hostapd_cli commands:
Enable extensibility tests:
set wps_version_number 0x57
Disable extensibility tests (WPS2 build):
set wps_version_number 0x20
Enable extra credential tests:
set wps_testing_dummy_cred 1
Disable extra credential tests:
set wps_testing_dummy_cred 0

ea184114ca Allow auto-connect to request scan in associating state
Disconnection event may be received while in associating state.
Previously, wpa_supplicant could get stuck not trying to reconnect
in that case at least with nl80211. Allow scan request in this
state to avoid the issue. This helps especially with APs that do
load balancing by sending Deauthentication frame as a response to
Reassociation Request frame after successful Authentication frame
exchange.
