Merge the practically copy-pasted implementations in wpa_supplicant and

configurator and boostrapping information. This avoid unnecessary code
duplication and provides a convenient location for adding new global DPP

The offset update for copying KEK2 from the extended PTK was overriding
the offset instead of incrementing it (a likely copy-paste error from
the first offset assignment based on KCK). This resulted in KEK2 being
set to incorrect segment of PTK. Fix this by updating the offset
properly so that KEK2 is copied from the correct place at the end of the
PTK.

Use Diffie-Hellman key exchange to derivate additional material for
PMK-to-PTK derivation to get PFS. The Diffie-Hellman Parameter element
(defined in OWE RFC 8110) is used in association frames to exchange the
DH public keys. For backwards compatibility, ignore missing
request/response DH parameter and fall back to no PFS in such cases.

DPP allows Diffie-Hellman exchange to be used for PFS in PTK derivation.
This requires an additional Z.x (x coordinate of the DH shared secret)
to be passed to wpa_pmk_to_ptk(). This commit adds that to the function
and updates all the callers to pass NULL,0 for that part in preparation
of the DPP specific changes to start using this.

The current/default behavior of set blacklist BSSID QCA vendor command
is a mandate to the driver - do not consider this BSSID for connect/roam
till reset.
There are use cases where this need not be a mandate and thus could
provide the flexibility for the driver to consider this BSSID if there
are no better ones. Such use cases can use this new flag attribute to
only hint the blacklist of a BSSID to the driver.

Do not start SAE authentication from scratch when the AP requests
anti-clogging token to be used. Instead, use the previously generated
PWE as-is if the retry is for the same AP and the same group. This saves
unnecessary processing on the station side in case the AP is under heavy
SAE authentiation load.

According to IEEE Std 802.11-2016, 9.4.2.25 when fields of an RSNE are
not included, the default values are used. The cipher suite defaults
were hardcoded to CCMP in the previous implementation, but the default
is actually different for DMG: GCMP (per 9.4.2.25.2).
It is not possible to find out from the RSNE if the network is non-DMG
or DMG, so callers of wpa_parse_wpa_ie_rsn() need to handle this case
based on context, which can be different for each caller.
In order to fix this issue, add flags to the wpa_ie_data indicating
whether pairwise/group ciphers were included in the RSNE. Callers can
check these flags and fill in the appropriate ciphers. The
wpa_parse_wpa_ie_rsn() function still initializes the ciphers to CCMP by
default so existing callers will not break. This change also fixes some
callers which need to handle the DMG network case.

Rather than always iterating elements from frames with pure
u8 pointers, add a type "struct element" that encapsulates
the id/datalen/data format of them.
Then, add the element iteration macros
* for_each_element
* for_each_element_id
* for_each_element_extid
which take, as their first 'argument', such a structure and
iterate through a given u8 array interpreting it as elements.
While at it also add
* for_each_subelement
* for_each_subelement_id
* for_each_subelement_extid
which instead of taking data/length just take an outer element
and use its data/datalen.
Also add for_each_element_completed() to determine if any of
the loops above completed, i.e., it was able to parse all of
the elements successfully and no data remained.

The vendor command QCA_NL80211_VENDOR_SUBCMD_AVOID_FREQUENCY was defined
to carry the list of avoid frequencies that aim to avoid any
interference with other coexistencies. This recommendation was followed
strictly by trying to prevent WLAN traffic on the impacted channels.
This commit refines the expectation of the interface by defining this
avoid channel list to allow minimal traffic but not heavier one. For
example, P2P may still be able to use avoid list frequencies for P2P
discovery and GO negotiation if the actual group can be set up on a not
impact channel.

These are not allowed in ISO C++ (and well, not really in ISO C either,
but that does not result in compiler warning without pedantic
compilation).
Since ieee802_11_common.h may end up getting pulled into C++ code for
some external interfaces, it is more convenient to keep it free of these
cases. Pull in ieee802_11_defs.h to get enum phy_type defined and move
enum chan_width to common/defs.h (which was already pulled in into
src/drivers/driver.h and src/common/ieee802_11_common.h).

While the AP is configured to enable both FT-PSK and WPA-PSK, an HP
printer request both AKMs (copied from AP?) in Association Request
frame, but don't add MDIE and don't use FT. This results in the
connection failing.
Next in logs we see:
RSN: Trying to use FT, but MDIE not included
IE - hexdump(len=26): 30 18 01 00 00 0f ac 04 01 00 00 0f ac 04

This is seen with some HP and Epson printers. Work around this by
stripping FT AKM(s) when MDE is not present and there is still a non-FT
AKM available.

The Android-specific chmod and chown operations on the client socket
(for communication with wpa_supplicant) did not protect against file
replacement between the bind() and chmod()/chown() calls. If the
directory in which the client socket is created (depends a bit on the
version and platform, but /data/misc/wifi/sockets is commonly used)
allows write access to processes that are different (less privileged)
compared to the process calling wpa_ctrl_open2(), it might be possible
to delete the socket file and replace it with something else (mainly, a
symlink) before the chmod/chown operations occur. This could have
resulted in the owner or permissions of the target of that symlink being
modified.
In general, it would be safest to use a directory which has more limited
write privileges (/data/misc/wifi/sockets normally has 'wifi' group
(AID_WIFI) with write access), but if that cannot be easily changed due
to other constraints, it is better to make wpa_ctrl_open2() less likely
to enable this type of race condition between the operations.
Replace chown() with lchown() (i.e., a version that does not dereference
symlinks) and chmod() with fchmod() on the socket before the bind() call
which is also not going to dereference a symlink (whereas chmod()
would). lchown() is a standard operation, but the fchmod() on the socket
is less so (unspecified behavior in some systems). However, it seems to
work on Linux and in particular, on Android, where this code is
executed.

This adds checks to common code to verify supported bandwidth options
for each channel using nl80211-provided info. No support of additional
modes is added, just additional checks. Such checks are needed because
driver/hardware can declare more strict limitations than declared in the
IEEE 802.11 standard. Without this patch hostapd might select
unsupported channel and that will fail because Linux kernel does check
channel bandwidth limitations.

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.

An AP might refuse to connect a STA if it has a low RSSI. In such case,
the AP informs the STA with the desired RSSI delta and a retry timeout.
Any subsequent association attempt with that AP (BSS) should be avoided,

expired.

This new QCA vendor command is used to query the supported AKM suite
selectors from the driver. There has been no such capability indication
from the driver and thus the current user space has to assume the driver
to support all the AKMs. This may be the case with some drivers (e.g.,
mac80211-based ones) but there are cfg80211-based drivers that implement
SME and have constraints on which AKMs can be supported (e.g., such
drivers may need an update to support SAE AKM using
NL80211_CMD_EXTERNAL_AUTH). Allow such drivers to specify the exact set
of supported AKMs so that user space tools can determine what network
profile options should be allowed to be configured. This command returns
the list of supported AKM suite selectors in the attribute
NL80211_ATTR_AKM_SUITES.
