2023-06-19wifi: ieee80211: use default for medium synchronization delayBenjamin Berg
Default values are defined for the information included in the Medium Synchronization Delay Information subfield. The spec says to initialize the values to these defaults and only change them when included. Return the default value instead of zero so that the defaults are used when the field is not included in the association response.

Add an explicit flexible array member and set it as the destination here, so that we get the correct coverage for the memcpy().

2022-12-01wifi: ieee80211: Do not open-code qos address offsetsKees Cook
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': drivers/net/wireless/intel/iwlwifi/mvm/rxmq.c:2022:29: warning: writing 1 byte into a region of size 0 [-Wstringop-overflow=] 2022 | *qc &= ~IEEE80211_QOS_CTL_A_MSDU_PRESENT; In file included from drivers/net/wireless/intel/iwlwifi/mvm/fw-api.h:32, from drivers/net/wireless/intel/iwlwifi/mvm/sta.h:15, from drivers/net/wireless/intel/iwlwifi/mvm/mvm.h:27, from drivers/net/wireless/intel/iwlwifi/mvm/rxmq.c:10: drivers/net/wireless/intel/iwlwifi/mvm/../fw/api/rx.h:559:16: note: at offset [78, 166] into destination object 'mpdu_len' of size 2 559 | __le16 mpdu_len; | ^~~~~~~~ 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.

2022-10-07wifi: fix multi-link element subelement iterationJohannes Berg
The subelements obviously start after the common data, including the common multi-link element structure definition itself. This bug was possibly just hidden by the higher bits of the control being set to 0, so the iteration just found one bogus element and most of the code could continue anyway.

2022-10-07wifi: mac80211: Parse station profile from association responseIlan Peer
When processing an association response frame for a Multi-Link connection, extract the per station profile for each additional link, and use it for parsing the link elements. 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.

2022-06-20wifi: cfg80211: do some rework towards MLO link APIsJohannes Berg
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.

2021-10-18treewide: Replace 0-element memcpy() destinations with flexible arraysKees Cook
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. Cc: "Gustavo A. R.
