Johannes Berg 31b5a54762 wifi: ieee80211: fix erroneous NSTR bitmap size checks
The complete profile bit together with the NSTR link pair
present bit indicate whether or not the NSTR bitmap is,
the NSTR bitmap size just indicates how big it is.

Make the data access a bit nicer overall by using structs. There is a
small change here to also accept a TBTT information length of eight

This also fixes a bug reading the short SSID on big endian machines.

Kees Cook 1a30a6b25f wifi: brcmfmac: p2p: Introduce generic flexible array frame member
Silence run-time memcpy() false positive warning when processing

Due to this (soon to be fixed) GCC bug[1], FORTIFY_SOURCE (via
__builtin_dynamic_object_size) doesn't recognize that the union may end
with a flexible array, and returns "26" (the fixed size of the union),
rather than the remaining size of the allocation. Add an explicit
flexible array member and set it as the destination here, so that we
get the correct coverage for the memcpy().

When building with -Wstringop-overflow, GCC's KASAN implementation does
not correctly perform bounds checking within some complex structures
when faced with literal offsets, and can get very confused. For example,
this warning is seen due to literal offsets into sturct ieee80211_hdr
that may or may not be large enough:

drivers/net/wireless/intel/iwlwifi/mvm/rxmq.c: In function 'iwl_mvm_rx_mpdu_mq':

Refactor ieee80211_get_qos_ctl() to avoid using literal offsets,
requiring the creation of the actual structure that is described in the
comments. Explicitly choose the desired offset, making the code more
human-readable too. This is one of the last remaining warning to fix
before enabling -Wstringop-overflow globally.

As the Multi-Link element might be fragmented, add support for
reassembling a fragmented element. To simplify memory management
logic, extend 'struct ieee802_11_elems' to hold a scratch buffer,
which is used for the defragmentation. Once an element is
reconstructed in the scratch area, point the corresponding element
pointer to it. Currently only defragmentation of Multi-Link element
and the contained per-STA profile subelement is supported.

Johannes Berg 7b0a0e3c3a wifi: cfg80211: do some rework towards MLO link APIs
In order to support multi-link operation with multiple links,
start adding some APIs. The notable addition here is to have
the link ID in a new nl80211 attribute, that will be used to
differentiate the links in many nl80211 operations.

So far, this patch adds the netlink NL80211_ATTR_MLO_LINK_ID
attribute (as well as the NL80211_ATTR_MLO_LINKS attribute)
and plugs it through the system in some places, checking the
validity etc. along with other infrastructure needed for it.

For now, I've decided to include only the over-the-air link
ID in the API. I know we discussed that we eventually need to
have to have other ways of identifying a link, but for local
AP mode and auth/assoc commands as well as set_key etc. we'll
use the OTA ID.

Also included in this patch is some refactoring of the data
structures in struct wireless_dev, splitting for the first
time the data into type dependent pieces, to make reasoning
about these things easier.

Miri Korenblit 091296d309 iwlwifi: mvm: refactor setting PPE thresholds in STA_HE_CTXT_CMD
We are setting the PPE Thresholds in STA_HE_CTXT_CMD according
to HE PHY Capabilities IE. As EHT is introduced, we will have to
set this thresholds according to EHT PHY Capabilities IE if we're
in an EHT connection. Some parts of the code can be used for both
HE and EHT. Put this parts in functions which will be used in the
patch which adds support for EHT PPE.

Kees Cook 47c662486c treewide: Replace 0-element memcpy() destinations with flexible arrays
The 0-element arrays that are used as memcpy() destinations are actually
flexible arrays. Adjust their structures accordingly so that memcpy()
can better reason able their destination size (i.e. they need to be seen
as "unknown" length rather than "zero").

In some cases, use of the DECLARE_FLEX_ARRAY() helper is needed when a
flexible array is alone in a struct.

Wen Gong 405fca8a94 ieee80211: add power type definition for 6 GHz
6 GHz regulatory domains introduces different modes for 6 GHz AP
operations: Low Power Indoor (LPI), Standard Power (SP) and Very
Low Power (VLP). 6 GHz STAs could be operated as either Regular or
Subordinate clients. Define the flags for power type
of AP and STATION mode.
