This code is dead, even old FW versions don't use it. The IWL_D0I3_RESET_REQUIRE flag will be sent by the FW via a notification, instead of command, the notification handler will be introduced later in the series.

2022-09-18wifi: iwlwifi: mvm: rxmq: refactor mac80211 rx_status settingJohannes Berg1-191/+165
There's a bunch of duplicated code in the normal data RX and the no-data RX paths, refactor that. Note that we're evidently not implementing the 6 GHz band in the no-data path correctly, need to fix that in firmware first. Also, we were setting the NSS differently, keep doing that, but just override the previous values. Note also that we used to drop frames with bad rate data, to simplify that just report rate 0 and continue.

2022-09-12wifi: iwlwifi: Mark IWLMEI as brokenToke Høiland-Jørgensen1-0/+1
The iwlmei driver breaks iwlwifi when returning from suspend. The interface ends up in the 'down' state after coming back from suspend. And iwd doesn't touch the interface state, but wpa_supplicant does, so the bug only happens on iwd. The bug report[0] has been open for four months now, and no fix seems to be forthcoming. Since just disabling the iwlmei driver works as a workaround, let's mark the config option as broken until it can be fixed properly.

2022-09-07wifi: iwlwifi: calib: Refactor iwl_calib_result usage for clarityKees Cook3-15/+17
In preparation for FORTIFY_SOURCE performing run-time destination buffer bounds checking for memcpy(), refactor the use of struct iwl_calib_result: - Have struct iwl_calib_result contain struct iwl_calib_cmd since functions expect to operate on the "data" flex array in "cmd", which follows the "hdr" member. - Switch argument passing around to use struct iwl_calib_cmd instead of struct iwl_calib_hdr to prepare functions to see the "data" member. - Change iwl_calib_set()'s "len" argument to a size_t since it is always unsigned and is normally receiving the output of sizeof(). - Add an explicit length sanity check in iwl_calib_set(). - Adjust the memcpy() to avoid copying across the now visible composite flex array structure. This avoids the future run-time warning: memcpy: detected field-spanning write (size 8) of single field "&res->hdr" (size 4) Cc: Luca Coelho <luciano.coelho@intel.com> Cc: Kalle Valo <kvalo@codeaurora.org> Cc: "David S.

2022-09-06wifi: mac80211: keep A-MSDU data in sta and per-linkBenjamin Berg5-21/+24
The A-MSDU data needs to be stored per-link and aggregated into a single value for the station. Add a new struct ieee_80211_sta_aggregates in order to store this data and a new function ieee80211_sta_recalc_aggregates to update the current data for the STA. Note that in the non MLO case the pointer in ieee80211_sta will directly reference the data in deflink.agg, which means that recalculation may be skipped in that case.

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing updates from Steven Rostedt: - Runtime verification infrastructure This is the biggest change here. It introduces the runtime verification that is necessary for running Linux on safety critical systems. It allows for deterministic automata models to be inserted into the kernel that will attach to tracepoints, where the information on these tracepoints will move the model from state to state. If a state is encountered that does not belong to the model, it will then activate a given reactor, that could just inform the user or even panic the kernel (for which safety critical systems will detect and can recover from). - Two monitor models are also added: Wakeup In Preemptive (WIP - not to be confused with "work in progress"), and Wakeup While Not Running (WWNR). - Added __vstring() helper to the TRACE_EVENT() macro to replace several vsnprintf() usages that were all doing it wrong. - eprobes now can have their event autogenerated when the event name is left off. - The rest is various cleanups and fixes. * tag 'trace-v6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: (50 commits) rv: Unlock on error path in rv_unregister_reactor() tracing: Use alignof__(struct {type b;}) instead of offsetof() tracing/eprobe: Show syntax error logs in error_log file scripts/tracing: Fix typo 'the the' in comment tracepoints: It is CONFIG_TRACEPOINTS not CONFIG_TRACEPOINT tracing: Use free_trace_buffer() in allocate_trace_buffers() tracing: Use a struct alignof to determine trace event field alignment rv/reactor: Add the panic reactor rv/reactor: Add the printk reactor rv/monitor: Add the wwnr monitor rv/monitor: Add the wip monitor rv/monitor: Add the wip monitor skeleton created by dot2k Documentation/rv: Add deterministic automata instrumentation documentation Documentation/rv: Add deterministic automata monitor synthesis documentation tools/rv: Add dot2k Documentation/rv: Add deterministic automaton documentation tools/rv: Add dot2c Documentation/rv: Add a basic documentation rv/include: Add instrumentation helper functions rv/include: Add deterministic automata monitor definition via C macros ...

Variadic functions (printf-like) undergo default argument promotion. Documentation/core-api/printk-formats.rst specifically recommends using the promoted-to-type's format flag. As per C11 6.3.1.1: (https://www.open-std.org/jtc1/sc22/wg14/www/docs/n1548.pdf) `If an int can represent all values of the original type ..., the value is converted to an int; otherwise, it is converted to an unsigned int. These are called the integer promotions.` Thus it makes sense to change `%hhu` to `%d` for both instances of the warning.

Instead of open coding a __dynamic_array() with a fixed length (which defeats the purpose of the dynamic array in the first place). Use the new __vstring() helper that will use a va_list and only write enough of the string into the ring buffer that is needed.

il4965_rs_fill_link_cmd() As a result of the execution of the inner while loop, the value of 'idx' can be equal to LINK_QUAL_MAX_RETRY_NUM. However, this is not checked after the loop and 'idx' is used to write the LINK_QUAL_MAX_RETRY_NUM size array 'lq_cmd->rs_table[idx]' below in the outer loop. The fix is to check the new value of 'idx' inside the nested loop, and break both loops if index equals the size. Checking it at the start is now pointless, so let's remove it.
