2020-07-31nl80211: support 4-way handshake offloading for WPA/WPA2-PSK in AP modeChung-Hsien Hsu
Let drivers advertise support for AP-mode WPA/WPA2-PSK 4-way handshake offloading with a new NL80211_EXT_FEATURE_4WAY_HANDSHAKE_AP_PSK flag. Extend use of NL80211_ATTR_PMK attribute indicating it might be passed as part of NL80211_CMD_START_AP command, and contain the PSK (which is the PMK, hence the name). The driver is assumed to handle the 4-way handshake by itself in this case, instead of relying on userspace.

2020-07-31cfg80211: invert HE BSS color 'disabled' to 'enabled'Johannes Berg
This is in fact 'disabled' in the spec, but there it's in a place where that actually makes sense. In our internal data structures, it doesn't really make sense, and in fact the previous commit just fixed a bug in that area. Make this safer by inverting the polarity from 'disabled' to 'enabled'.

2020-07-31mac80211: parse radiotap header when selecting Tx queueMathy Vanhoef
Already parse the radiotap header in ieee80211_monitor_select_queue. In a subsequent commit this will allow us to add a radiotap flag that influences the queue on which injected packets will be sent. This also fixes the incomplete validation of the injected frame in ieee80211_monitor_select_queue: currently an out of bounds memory access may occur in in the called function ieee80211_select_queue_80211 if the 802.11 header is too small. Note that in ieee80211_monitor_start_xmit the radiotap header is parsed again, which is necessairy because ieee80211_monitor_select_queue is not always called beforehand.

2020-07-31cfg80211/mac80211: add mesh_param "mesh_nolearn" to skip path discoveryLinus Lüssing
Currently, before being able to forward a packet between two 802.11s nodes, both a PLINK handshake is performed upon receiving a beacon and then later a PREQ/PREP exchange for path discovery is performed on demand upon receiving a data frame to forward. When running a mesh protocol on top of an 802.11s interface, like batman-adv, we do not need the multi-hop mesh routing capabilities of 802.11s and usually set mesh_fwding=0. However, even with mesh_fwding=0 the PREQ/PREP path discovery is still performed on demand. Even though in this scenario the next hop PREQ/PREP will determine is always the direct 11s neighbor node. The new mesh_nolearn parameter allows to skip the PREQ/PREP exchange in this scenario, leading to a reduced delay, reduced packet buffering and simplifies HWMP in general. mesh_nolearn is still rather conservative in that if the packet destination is not a direct 11s neighbor, it will fall back to PREQ/PREP path discovery. For normal, multi-hop 802.11s mesh routing it is usually not advisable to enable mesh_nolearn as a transmission to a direct but distant neighbor might be worse than reaching that same node via a more robust / higher throughput etc. multi-hop path.

2020-07-31cfg80211: allow the low level driver to flush the BSS tableEmmanuel Grumbach
The low level driver adds its own opaque information in the BSS table in the cfg80211_bss structure. The low level driver may need to signal that this information is no longer relevant and needs to be recreated. Add an API to allow the low level driver to do that. iwlwifi needs this because it keeps there an information about the firmware's internal clock. This is kept in mac80211's struct ieee80211_bss::sync_device_ts. This information is populated while we scan, we add the internal firmware's clock to each beacon which allows us to program the firmware correctly after association so that it'll know when (in terms of its internal clock) the DTIM and TBTT will happen. When the firmware is reset this internal clock is reset as well and ieee80211_bss::sync_device_ts is no longer accurate. iwlwifi will call this new API any time the firmware is started.

2020-07-30mm: pgtable: Make generic pgprot_* macros available for no-MMUPekka Enberg
The <linux/pgtable.h> header defines some generic pgprot_* implementations, but they are only available when CONFIG_MMU is enabled. The RISC-V architecture, for example, therefore defines some of these pgprot_* macros for !NOMMU. Let's make the pgprot_* generic available even for !NOMMU so we can remove the RISC-V specific definitions. Compile-tested with x86 defconfig, and riscv defconfig and !MMU defconfig.

2020-07-30tasklet: Introduce new initialization APIRomain Perier
Nowadays, modern kernel subsystems that use callbacks pass the data structure associated with a given callback as argument to the callback. The tasklet subsystem remains one which passes an arbitrary unsigned long to the callback function. This has several problems: - This keeps an extra field for storing the argument in each tasklet data structure, it bloats the tasklet_struct structure with a redundant .data field - No type checking can be performed on this argument. Instead of using container_of() like other callback subsystems, it forces callbacks to do explicit type cast of the unsigned long argument into the required object type. - Buffer overflows can overwrite the .func and the .data field, so an attacker can easily overwrite the function and its first argument to whatever it wants. Add a new tasklet initialization API, via DECLARE_TASKLET() and tasklet_setup(), which will replace the existing ones. This work is greatly inspired by the timer_struct conversion series, see commit e99e88a9d2b0 ("treewide: setup_timer() -> timer_setup()") To avoid problems with both -Wcast-function-type (which is enabled in the kernel via -Wextra is several subsystems), and with mismatched function prototypes when build with Control Flow Integrity enabled, this adds the "use_callback" member to let the tasklet caller choose which union member to call through. Once all old API uses are removed, this and the .data member will be removed as well. (On 64-bit this does not grow the struct size as the new member fills the hole after atomic_t, which is also "int" sized.)

2020-07-30treewide: Replace DECLARE_TASKLET() with DECLARE_TASKLET_OLD()Kees Cook
This converts all the existing DECLARE_TASKLET() (and ...DISABLED) macros with DECLARE_TASKLET_OLD() in preparation for refactoring the tasklet callback type. All existing DECLARE_TASKLET() users had a "0" data argument, it has been removed here as well.
