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.

For non-MLO, the station directory will be used directly rather than creating a corresponding subdirectory. As such, non-MLO drivers can simply continue to create the data from sta_debugfs_add.

Different wireless events may have different payload structure and size, so kernel uses **len** and **cmd** field in struct __compat_iw_event as wireless event common LCP part, uses **pointer** as a label to mark the position of remaining different part. Yet the problem is that, **pointer** is a compat_caddr_t type, which may be smaller than the relative structure at the same position. So during wireless_send_event() tries to parse the wireless events payload, it may trigger the memcpy() run-time destination buffer bounds checking when the relative structure's data is copied to the position marked by **pointer**. This patch solves it by introducing flexible-array field **ptr_bytes**, to mark the position of the wireless events remaining part next to LCP part. What's more, this patch also adds **ptr_len** variable in wireless_send_event() to improve its maintainability.

2022-10-07wifi: mac80211: netdev compatible TX stop for iTXQ driversAlexander Wetzel
Properly handle TX stop for internal queues (iTXQs) within mac80211. mac80211 must not stop netdev queues when using mac80211 iTXQs. For these drivers the netdev interface is created with IFF_NO_QUEUE. While netdev still drops frames for IFF_NO_QUEUE interfaces when we stop the netdev queues, it also prints a warning when this happens: Assuming the mac80211 interface is called wlan0 we would get "Virtual device wlan0 asks to queue packet!" when netdev has to drop a frame.

2022-10-07wifi: mac80211: remove/avoid misleading printsJames Prestwood
At some point a few kernel debug prints started appearing which indicated something was sending invalid IEs: "bad VHT capabilities, disabling VHT" "Invalid HE elem, Disable HE" Turns out these were being printed because the local hardware supported HE/VHT but the peer/AP did not. Bad/invalid indicates, to me at least, that the IE is in some way malformed, not missing. For the HE print (ieee80211_verify_peer_he_mcs_support) it will now silently fail if the HE capability element is missing (still prints if the element size is wrong). For the VHT print, it has been removed completely and will silently set the DISABLE_VHT flag which is consistent with how DISABLE_HT is set.

2022-10-05wifi: atmel: Avoid clashing function prototypesKees Cook
When built with Control Flow Integrity, function prototypes between caller and function declaration must match. These mismatches are visible at compile time with the new -Wcast-function-type-strict in Clang[1]. Of the 1549 warnings found, 188 come from the atmel driver. For example: drivers/net/wireless/atmel/atmel.c:2518:2: warning: cast from 'int (*)(struct net_device *, struct iw_request_info *, void *, char *)' to 'iw_handler' (aka 'int (*)(struct net_device *, struct iw_request_info *, union iwreq_data *, char *)') converts to incompatible function type [-Wcast-function-type-strict] (iw_handler) atmel_config_commit, /* SIOCSIWCOMMIT */ ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The atmel Wireless Extension handler callbacks (iw_handler) use a union for the data argument. Actually use the union and perform explicit member selection in the function body instead of having a function prototype mismatch. There are no resulting binary differences. This patch is a cleanup based on Brad Spengler/PaX Team's modifications to the atmel driver in their last public patch of grsecurity/PaX based on my understanding of the code. Changes or omissions from the original code are mine and don't reflect the original grsecurity/PaX code.

Expose crash_kexec() to allow BPF to trigger a kernel dump. Use CAP_SYS_BOOT check on the loading process to judge permissions. - Enable BPF to collect custom hierarchical cgroup stats efficiently by integrating with the rstat framework. - Support struct arguments for trampoline based programs. Only structs with size <= 16B and x86 are supported. - Invoke cgroup/connect{4,6} programs for unprivileged ICMP ping sockets (instead of just TCP and UDP sockets). - Add a helper for accessing CLOCK_TAI for time sensitive network related programs. - Support accessing network tunnel metadata's flags. - Make TCP SYN ACK RTO tunable by BPF programs with TCP Fast Open. - Add support for writing to Netfilter's nf_conn:mark.

This allows us to cache the information and improve performance slightly. - Use the time_after() macro to do time comparisons instead of doing it directly and potentially causing ourselves problems when the timer wraps. - Convert an audit_context state comparison from a relative enum comparison, e.g. (x < y), to a not-equal comparison to ensure that we are not caught out at some unknown point in the future by an enum shuffle. - A handful of small cleanups such as tidying up comments and removing unused declarations" * tag 'audit-pr-20221003' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit: audit: remove selinux_audit_rule_update() declaration audit: use time_after to compare time audit: free audit_proctitle only on task exit audit: explicitly check audit_context->context enum value audit: audit_context pid unused, context enum comment fix audit: fix repeated words in comments

2022-10-04brcmfmac: return error when getting invalid max_flowrings from dongleWright Feng
When firmware hit trap at initialization, host will read abnormal max_flowrings number from dongle, and it will cause kernel panic when doing iowrite to initialize dongle ring. To detect this error at early stage, we directly return error when getting invalid max_flowrings(>256).

2022-10-04brcmfmac: Fix authentication latency caused by OBSS stats surveyRamesh Rangavittal
Auto Channel Select feature of HostAP uses dump_survey to fetch OBSS statistics. When the device is in the middle of an authentication sequence or just at the end of authentication completion, running dump_survey would trigger a channel change. The channel change in-turn can cause packet loss, resulting in authentication delay. With this change, dump_survey won't be run when authentication or association is in progress, hence resolving the issue.
