2021-09-28Revert "brcmfmac: use ISO3166 country code and 0 rev as fallback"Soeren Moch
This reverts commit b0b524f079a23e440dd22b04e369368dde847533. Commit b0b524f079a2 ("brcmfmac: use ISO3166 country code and 0 rev as fallback") changes country setup to directly use ISO3166 country codes if no more specific code is configured. This was done under the assumption that brcmfmac firmwares can handle such simple direct mapping from country codes to firmware ccode values. Unfortunately this is not true for all chipset/firmware combinations. E.g. BCM4359/9 devices stop working as access point with this change, so revert the offending commit to avoid the regression.

2021-09-24ath11k: monitor mode clean up to use separate APIsSeevalamuthu Mariappan
If monitor interface is enabled in co-exist mode, only local traffic are captured. It's caused by missing monitor vdev in co-exist mode. So, monitor mode clean up is done with separate Monitor APIs. For this, introduce flags monitor_started and monitor_vdev_created.

2021-09-24brcmfmac: Replace zero-length array with flexible array memberLen Baker
There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use "flexible array members"[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. Also, make use of the struct_size() helper in devm_kzalloc().

2021-09-23mac80211-hwsim: fix late beacon hrtimer handlingJohannes Berg
Thomas explained in https://lore.kernel.org/r/87mtoeb4hb.ffs@tglx that our handling of the hrtimer here is wrong: If the timer fires late (e.g. due to vCPU scheduling, as reported by Dmitry/syzbot) then it tries to actually rearm the timer at the next deadline, which might be in the past already: 1 2 3 N N+1 | | | ... | | ^ intended to fire here (1) ^ next deadline here (2) ^ actually fired here The next time it fires, it's later, but will still try to schedule for the next deadline (now 3), etc. until it catches up with N, but that might take a long time, causing stalls etc. Now, all of this is simulation, so we just have to fix it, but note that the behaviour is wrong even per spec, since there's no value then in sending all those beacons unaligned - they should be aligned to the TBTT (1, 2, 3, ... in the picture), and if we're a bit (or a lot) late, then just resume at that point. Therefore, change the code to use hrtimer_forward_now() which will ensure that the next firing of the timer would be at N+1 (in the picture), i.e. the next interval point after the current time.

2021-09-21rsi: Fix module dev_oper_mode parameter descriptionMarek Vasut
The module parameters are missing dev_oper_mode 12, BT classic alone, add it. Moreover, the parameters encode newlines, which ends up being printed malformed e.g. by modinfo, so fix that too. However, the module parameter string is duplicated in both USB and SDIO modules and the dev_oper_mode mode enumeration in those module parameters is a duplicate of macros used by the driver. Furthermore, the enumeration is confusing. So, deduplicate the module parameter string and use __stringify() to encode the correct mode enumeration values into the module parameter string. Finally, replace 'Wi-Fi' with 'Wi-Fi alone' and 'BT' with 'BT classic alone' to clarify what those modes really mean.

When creating a new virtual interface in mwifiex_add_virtual_intf(), we update our internal driver states like bss_type, bss_priority, bss_role and bss_mode to reflect the mode the firmware will be set to. When switching virtual interface mode using mwifiex_init_new_priv_params() though, we currently only update bss_mode and bss_role. In order for the interface mode switch to actually work, we also need to update bss_type to its proper value, so do that.

So allow type changes between P2P_CLIENT and P2P_GO and simply call into mwifiex_change_vif_to_p2p(), which handles this just fine.

2021-09-21mwifiex: Update virtual interface counters right after setting bss_typeJonas Dreßler
In mwifiex_init_new_priv_params() we update our private driver state to reflect the currently selected virtual interface type. Most notably we set the bss_mode to the mode we're going to put the firmware in. Now after we updated the driver state we actually start talking to the firmware and instruct it to set up the new mode. Those commands can and will sometimes fail, in which case we return with an error from mwifiex_change_vif_to_*. We currently update our virtual interface type counters after this return, which means the code is never reached when a firmware error happens and we never update the counters. Since we have updated our bss_mode earlier though, the counters now no longer reflect the actual state of the driver. This will break things on the next virtual interface change, because the virtual interface type we're switching away from didn't get its counter incremented, and we end up decrementing a 0-counter. To fix this, simply update the virtual interface type counters right after updating our driver structures, so that they are always in sync.

We currently handle changing from the P2P to the STATION virtual interface type slightly different than changing from P2P to ADHOC: When changing to STATION, we don't send the SET_BSS_MODE command. We do send that command on all other type-changes though, and it probably makes sense to send the command since after all we just changed our BSS_MODE. Looking at prior changes to this part of the code, it seems that this is simply a leftover from old refactorings. Since sending the SET_BSS_MODE command is the only difference between mwifiex_change_vif_to_sta_adhoc() and the current code, we can now use mwifiex_change_vif_to_sta_adhoc() for both switching to ADHOC and STATION interface type. This does not fix any particular bug and just "looked right", so there's a small chance it might be a regression.

2021-09-21mwifiex: Small cleanup for handling virtual interface type changesJonas Dreßler
Handle the obvious invalid virtual interface type changes with a general check instead of looking at the individual change. For type changes from P2P_CLIENT to P2P_GO and the other way round, this changes the behavior slightly: We now still do nothing, but return -EOPNOTSUPP instead of 0. Now that behavior was incorrect before and still is, because type changes between these two types are actually possible and supported, which we'll fix in a following commit.

2021-09-21rtw88: move adaptivity mechanism to firmwareChin-Yen Lee
Current adaptivity mechanism is achieved in driver, by periodically referencing the IGI value and then updating related registers. But we find that this way may halt TX activity too long if huge and temporary energy is detected frequently. So we move the mechanism to firmware for immediately reacting this case to recover TX rapidly.

2021-09-21rtw88: support adaptivity for ETSI/JP DFS regionZong-Zhe Yang
Add Energy Detected CCA (EDCCA) mechanism to detect energy on the channel. And EDCCA support adaptivity mode now. From MIC Ordinance Regulating Radio Equipment article 49.20, ETSI EN-300-328 and EN-301-893, the device should be able to dynamically pause TX activity when energy detected on the air. According to ETSI/JP DFS region, driver will set corresponding threshold and stop TX activity if the detected energy exceeds the threshold. For now, we support it on 8822b and 8822c first. By default, EDCCA mechanism is turned on. For ETSI/JP DFS region, it will turn to adaptivity mode. However, with adaptivity, if environment is too noisy, TX may often be halted. So, a debugfs for EDCCA is added. It can show what EDCCA mode is used currently. And EDCCA mechanism can be turned on/off through the debugfs while debugging.

2021-09-21rtw88: add regulatory strategy by chip typeZong-Zhe Yang
Realtek chips can program a specific country domain on efuse to indicate what is the expected rtw_regulatory. For chips with a programmed country domain, we set REGULATORY_STRICT_REG to tell stack to consider follow-up regulatory_hint() as the superset of our regulatory rule. Besides, on driver side, only the request via NL80211_REGDOM_SET_BY_DRIVER, which matches programmed country domain, will be handled to keep rtw_regulatory unchanged. For worldwide roaming chips, i.e. ones without a specific programmed country domain, system of distro can set expected regulatory via NL80211_REGDOM_SET_BY_USER. With setting from it, rtw_regulatory will handle the requests only via NL80211_REGDOM_SET_BY_USER to follow setting from system of distro. REGULATORY_COUNTRY_IE_IGNORE will then be set to tell stack to ignore country IE for us. The restrictions mentioned above will remain until 00, i.e. worldwide, is set via NL80211_REGDOM_SET_BY_USER. On the other hand, for worldwide roamin chips, if there is no specific regulatory set via NL80211_REGDOM_SET_BY_USER, requests from all regulatory notifications will be handled by rtw_regulatory. And REGULATORY_COUNTRY_IE_IGNORE won't be set.

2021-09-21rtw88: upgrade rtw_regulatory mechanism and mappingZong-Zhe Yang
Mapping table from country code to rtw_regulatory, which manages tx power limit according to countries, is updated. And mapping architecture is also upgraded. For more precise control on tx power limit, it allows different rtw_regulatory for different bands logically. Besides, a helper function to query rtw_regulatory for current band under current country is provided. For older chips, some newly added rtw_regulatory may not be configured. To avoid that those chips have no limit on some countries mapping to a newer rtw_regulatory after table update, a backward selection mechanism of rtw_regulatory is introduced. It can help chips use a rtw_regulatory which has been configured as an alternative of a newer one which is not configured. In addition, rtw88 actually doesn't manage channel plans by itself. Instead, it follows them from stack. So, correct some naming about chplan with regd, and remove the unnecessary channel control for now.

2021-09-21wcn36xx: Implement Idle Mode Power SaveBryan O'Donoghue
Idle Mode Power Save (IMPS) is a power saving mechanism which when called by wcn36xx will cause the radio hardware to enter power collapse. This particular call maps nicely to a simple conjunction/disjunction around IEEE80211_CONF_CHANGE_IDLE and IEEE80211_CONF_IDLE. Here we enter idle when we are not associated with an AP. The kernel will incrementally toggle idle on/off in the process of trying to establish a connection, thus saving power until we are connected to the AP again, at which point we give way to BMPS if power_save is on. We've validated that with IMPS an apq8039 device which has the wcn36xx module loaded but, has not authenticated with an AP will get to VMIN on suspend and will not without IMPS.

2021-09-21wcn36xx: Fix Antenna Diversity SwitchingBryan O'Donoghue
We have been tracking a strange bug with Antenna Diversity Switching (ADS) on wcn3680b for a while. ADS is configured like this: A. Via a firmware configuration table baked into the NV area. 1. Defines if ADS is enabled. 2. Defines which GPIOs are connected to which antenna enable pin. 3. Defines which antenna/GPIO is primary and which is secondary. B. WCN36XX_CFG_VAL(ANTENNA_DIVERSITY, N) N is a bitmask of available antenna. Setting N to 3 indicates a bitmask of enabled antenna (1 | 2). Obviously then we can set N to 1 or N to 2 to fix to a particular antenna and disable antenna diversity. C. WCN36XX_CFG_VAL(ASD_PROBE_INTERVAL, XX) XX is the number of beacons between each antenna RSSI check. Setting this value to 50 means, every 50 received beacons, run the ADS algorithm. D. WCN36XX_CFG_VAL(ASD_TRIGGER_THRESHOLD, YY) YY is a two's complement integer which specifies the RSSI decibel threshold below which ADS will run. We default to -60db here, meaning a measured RSSI <= -60db will trigger an ADS probe. E. WCN36XX_CFG_VAL(ASD_RTT_RSSI_HYST_THRESHOLD, Z) Z is a hysteresis value, indicating a delta which the RSSI must exceed for the antenna switch to be valid. For example if HYST_THRESHOLD == 3 AntennaId1-RSSI == -60db and AntennaId-2-RSSI == -58db then firmware will not switch antenna. The threshold needs to be -57db or better to satisfy the criteria. F. A firmware feature bit also exists ANTENNA_DIVERSITY_SELECTION. This feature bit is used by the firmware to report if ANTENNA_DIVERSITY_SELECTION is supported. The host is not required to toggle this bit to enable or disable ADS. ADS works like this: A. Every XX beacons the firmware switches to or remains on the primary antenna. B. The firmware then sends a Request-To-Send (RTS) packet to the AP. C. The firmware waits for a Clear-To-Send (CTS) response from the AP. D. The firmware then notes the received RSSI on the CTS packet. E. The firmware then repeats steps A-D on the secondary antenna. F. Subsequently if the RSSI on the measured antenna is better than ASD_TRIGGER_THRESHOLD + the active antenna's RSSI then the measured antenna becomes the active antenna. G. If RSSI rises past ASD_TRIGGER_THRESHOLD then ADS doesn't run at all even if there is a substantially better RSSI on the alternative antenna. What we have been observing is that the RTS packet is being sent but the MAC address is a byte-swapped version of the target MAC. The ADS/RTS MAC is corrupted only when the link is encrypted, if the AP is open the RTS MAC is correct. Similarly if we configure the firmware to an RTS/CTS sequence for regular data - the transmitted RTS MAC is correctly formatted. Internally the wcn36xx firmware uses the indexes in the SMD commands to populate and extract data from specific entries in an STA lookup table. The AP's MAC appears a number of times in different indexes within this lookup table, so the MAC address extracted for the data-transmit RTS and the MAC address extracted for the ADS/RTS packet are not the same STA table index. Our analysis indicates the relevant firmware STA table index is "bssSelfStaIdx". There is an STA populate function responsible for formatting the MAC address of the bssSelfStaIdx including byte-swapping the MAC address. Its clear then that the required STA populate command did not run for bssSelfStaIdx. So taking a look at the sequence of SMD commands sent to the firmware we see the following downstream when moving from an unencrypted to encrypted BSS setup. - WLAN_HAL_CONFIG_BSS_REQ - WLAN_HAL_CONFIG_STA_REQ - WLAN_HAL_SET_STAKEY_REQ Upstream in wcn36xx we have - WLAN_HAL_CONFIG_BSS_REQ - WLAN_HAL_SET_STAKEY_REQ The solution then is to add the missing WLAN_HAL_CONFIG_STA_REQ between WLAN_HAL_CONFIG_BSS_REQ and WLAN_HAL_SET_STAKEY_REQ. No surprise WLAN_HAL_CONFIG_STA_REQ is the routine responsible for populating the STA lookup table in the firmware and once done the MAC sent by the ADS routine is in the correct byte-order. This bug is apparent with ADS but it is also the case that any other firmware routine that depends on the "bssSelfStaIdx" would retrieve malformed data on an encrypted link.

2021-09-21rsi: fix rate mask set leading to P2P failureMartin Fuzzey
P2P client mode was only working the first time. On subsequent connection attempts the group was successfully created but no data was sent (no transmitted data packets were seen with a sniffer). The reason for this was that the hardware was being configured in fixed rate mode with rate RSI_RATE_1 (1Mbps) which is not valid in the 5GHz band. In P2P mode wpa_supplicant uses NL80211_CMD_SET_TX_BITRATE_MASK to disallow the 11b rates in the 2.4GHz band which updated common->fixedrate_mask. rsi_set_min_rate() then used the fixedrate_mask to calculate the minimum allowed rate, or 0xffff = auto if none was found. However that calculation did not account for the different rate sets allowed in the different bands leading to the error. Fixing set_min_rate() would result in 6Mb/s being used all the time which is not what we want either. The reason the problem did not occur on the first connection is that rsi_mac80211_set_rate_mask() only updated the fixedrate_mask for the *current* band. When it was called that was still 2.4GHz as the switch is done later. So the when set_min_rate() was subsequently called after the switch to 5GHz it still had a mask of zero, leading to defaulting to auto mode. Fix this by differentiating the case of a single rate being requested, in which case the hardware will be used in fixed rate mode with just that rate, and multiple rates being requested, in which case we remain in auto mode but the firmware rate selection algorithm is configured with a restricted set of rates.

2021-09-21rsi: fix key enabled check causing unwanted encryption for vap_id > 0Martin Fuzzey
My previous patch checked if encryption should be enabled by directly checking info->control.hw_key (like the downstream driver). However that missed that the control and driver_info members of struct ieee80211_tx_info are union fields. Due to this when rsi_core_xmit() updates fields in "tx_params" (driver_info) it can overwrite the control.hw_key, causing the result of the later test to be incorrect. With the current structure layout the first byte of control.hw_key is overlayed with the vap_id so, since we only test if control.hw_key is NULL / non NULL, a non zero vap_id will incorrectly enable encryption. In basic STA and AP modes the vap_id is always zero so it works but in P2P client mode a second VIF is created causing vap_id to be non zero and hence encryption to be enabled before keys have been set. Fix this by extracting the key presence flag to a new field in the driver private tx_params structure and populating it first.

Running a userspace loop that resets the hardware via a GPIO shows the problem occurring ~5/100 resets. The problem does not occur in oper mode 1 (wifi only). Adding logs shows that the initialisation state machine requests a MAC reset via rsi_send_reset_mac() but the firmware does not reply, leading to the initialisation sequence being incomplete. Fix this by delaying attaching the BT adapter until the wifi initialisation has completed. With this applied I have done > 300 reset loops with no errors.
