hostapd: Respect obss_interval on 40 MHz intolerant disconnect
When an AP is configured for HT operation on 40 MHz but has overlapping
BSS on the secondary channel, it will fall back to 20 MHz only. Also a
40 MHz AP will downgrade to 20 MHz while at least one 40 MHz intolerant
STA is connected.
However, in the current code, on such an AP, we do not check the
obss_interval parameter to be set on the last 40 MHz intolerant STA
disconnect and instead, start a timer that will unconditionnaly and
immediately bring the AP to 40 MHz operation even if it had overlapping
BSS.
A similar case was addressed for the 20/40 MHz co-ex report earlier in
commit d027c7b118fe ("Fix 20/40 MHz co-ex report processing with
obss_interval=0"), but this other case that gets called whenever a STA
entry is removed needs to have similar constraint on starting the timer.

ext_password_file: Do not use wpa_config_get_line()
The file-based backed of the ext_password framework uses
wpa_config_get_line() to read the passwords line-by-line from a file.
This function is meant to parse a single line from the
wpa_supplicant.conf file, so it handles whitespace, quotes and other
characters specially.
Its behavior, however, it's not compatible with the rest of the
ext_password framework implementation. For example, if a passphrase
contains a `#` character it must be quoted to prevent parsing the
remaining characters as an inline comment, but the code handling the
external password in wpa_supplicant_get_psk() does not handle quotes.
The result is that either it will hash the enclosing quotes, producing a
wrong PSK, or if the passphrase is long enough, fail the length check.
As a consequence, some passphrases are impossible to input correctly.
To solve this and other issues, this patch changes the behaviour of the
ext_password_file_get() function (which was not documented in details,

literally: including trailing whitespaces (except CR and LF), `#` for

nl80211: Use nl80211_bss_msg() helper wherever BSS is accessible
With single drv changes, the drv structure is no longer tightly coupled
with a single radio. Currently, many nl80211 commands assume this
coupling and send commands to drv->first_bss or drv->ifindex, which may
not be the intended BSS. Consequently, the kernel rejects these
commands.
To resolve this issue, use the provided BSS or bss->ifindex to construct
the message, ensuring it is sent to the correct radio's interface.
hostapd: Maintain single wpa_driver_nl80211_data (drv) object across interfaces
Currently, the first BSS of each hostapd interface (struct hostapd_iface)
creates a new driver data object (struct wpa_driver_nl80211_data, referred
to as drv). When a non-first BSS of an interface initializes, it copies the
drv_priv and thus uses the first BSS’s drv object. This can lead to
situations where multiple drv objects are maintained for the same
underlying hardware in hostapd.
Some of such situations are:
1. Two different configs for two different wlanX interface but on the
same underlying radio. In this case, two drv objects will be
maintained.
2. MLO case - 5 GHz config having two BSS. 6 GHz config having one BSS.
5 GHz's second BSS is partnering with 6 GHz's BSS and forming MLD.
And 6 GHz config is enabled first and then 5 GHz. In this case, two
different driver instance will be maintained - one having 5 GHz BSS
and other having 5 GHz + 6 GHz MLO BSS. To visualize this:
Assumption: Only 1 phy (say phy0 exist on system). On this phy, the driver
has grouped both 5 GHz and 6 GHz underlying radio as a single
radio.
Config:
+--------------------+ +------------------+
| 5 GHz config | | 6 GHz config |
| | | |
| | | |
| +----------------+ | | |
| | BSS 1 | | | |
| | ssid: guest_ap | | | |
| +----------------+ | | |
| | | |
+------------------------------------------------------------------+
| | +----------------+ | | +--------------+ | |
| | | BSS 2 | | | | BSS 1 | | |

| | +----------------+ | | +--------------+ | |
| +--------------------+ +------------------+ |
+------------------------------------------------------------------+
With this change, it will behave as per the expectation.
3. Three different underlying hardwares - 2.4 GHz, 5 GHz, 6 GHz, capable
of three different bands and they are grouped together and advertised
as single hardware supporting all bands to upper layer. In this case,
if one interface (wlanX) is enabled in each hardware (three
independent configs) three different drv will be maintained.
Because of this, at times during de-initialization, proper
deinitialization will not happen and WPA_TRACE could be seen:
Also, for situation #3, during handling of incoming NL commands, the
above is causing issue in routing the events. This is because since all
underlying hardwares are part of same phy, phy index is same in all the
drv objects. Hence when the event comes, it will be given to the first
drv which might not be having the intended BSS. For example, 5 GHz DFS
events (which does not have if_idx). The event can be passed to driver
having 2.4 GHz's BSS or 6 GHz's depending upon which was enabled first.
Hence to avoid these situations, try to maintain single drv object as
much as possible.

Add a vendor attribute to disable DFS owner capability
Add a u8 attribute QCA_WLAN_VENDOR_ATTR_CONFIG_DFS_OWNER_DISABLE to
disable DFS owner capability dynamically:
1: disable DFS owner capability in the driver.
0: reset DFS owner capability to the default DFS owner capability of
the driver.
If DFS owner capability is disabled, the driver will not start AP mode
operations on DFS channels, and all the features depending on DFS owner
functionality will not be supported.
