We were hardcoding the SnJ and So IDs already at the trans_cfg selection, instead of doing it in a more generic way. Use the generic trans_cfg selection for these devices and move the hardcoded IDs to the new table. Signed-off-by:

The "supp" variable doesn't need to be unsigned long, only "tmp" is used with for_each_set_bit(). "supp" should just be a u16, since that's how it's sent to the firmware. Signed-off-by:

In struct iwl_tx_cmd, there's no risk (as Arnd implied) that we might access this as an array, as it's really not an array and cannot be - there's only a single 802.11 header per frame. The only reason for this member is for being able to access it a bit more nicely. On the other hand, this structure is used as a sub-struct in a few places, and then some compilers (e.g. clang with certain options) complain as you shouldn't have structs with variable- length fields embedded in other structs.

If the firmware has support, then advertise it to the stack and send the key down. Since we re-check the protection in the host anyway, we don't really need to do anything on RX except that we should drop frames that the firmware _knows_ are replay errors, since beacon filtering might otherwise result in replays being possible.

On devices starting from 9000 series, always allow maximum A-MSDU sizes regardless of the amsdu_size module parameter, which really hasn't meant that for a long time but just controls the receive buffer size. Signed-off-by:

When we check the length, we only check that the advertised data length fits into the data we have, but currently not that it actually matches correctly. This should be harmless, but if the first two bytes are zero, then the iwl_rx_packet_payload_len() ends up negative, and that might later cause issues if unsigned variables are used, as this is not something that's normally expected. Change the validation here to precisely validate the lengths match, to avoid such issues. Signed-off-by:

Handling host commands in a sync way is not directly related to PCIe transport, and can serve as common logic for any transport, so move it to trans layer. Signed-off-by:

In roaming flows and during reassociation, its possible that data frames such as EAPOLs for 4 way handshake/ 802.1x authentication are initially set to higher MCS rate. Though these are pruned down to a lower legacy rate before sending to the FW, driver also emits a kernel warning - intended for non-data frames. Add checks to avoid such warnings for data frames, while also enhancing the debug data printed. Signed-off-by:

While disconnecting from the AP due to bad channel switch params (e.g. too long Tx block), do not send the firmware 'CSA abort' before disconnecting. That causes canceling the immediate quiet and can cause transmitting data before the disconnection happens. Signed-off-by:

D3_CONFIG_CMD and D0I3_END_CMD should be the last\first command upon suspend\resume correspondingly, otherwise, FW will raise an assert (0x342). There are firmware notifications that cause the driver to send a command back to the firmware. If such a notification is sent to the driver while the the driver prepares the firmware for D3, operation, what is likely to happen is that the handling of the notification will try to get the mutex and will wait unil the driver finished configuring the firmware for D3. Then the handling notification will get the mutex and handle the notification which will lead to the aforementioned ASSERT 342. To avoid this, we need to prevent any command to be sent to the firmware between the D3_CONFIG_CMD and the D0I3_END_CMD. Check this in the utility layer that sends the host commands and in the transport layer as well. Flag the D3_CONFIG_CMD and the D0I3_END_CMD commands as commands that must be sent even if the firmware has already been configured for D3 operation. Signed-off-by:

When we want to stop TX'ing because we are suspending, we have two options: either we check system_pm_mode or we check the mvm's status that has a bit for the suspend flow. The latter is better because test_bit is atomic. Also add a call to synchronize_net after we set the bit to make sure that all the new Tx see the bit before we actually complete the suspend flow.

In the new api all the flush in the FW is done before we get the response and in the response we only get the updated read pointer and all queued packets don't get anymore rx_tx per packet to free the queued packet, so driver needs to free all queued packets on flushed queue at once after flush response.

If there are frequent CCA delays due to the extension channel as detected by the firmware, and we're on 2.4 GHz, then handle this by disconnecting (with a reconnect hint). When we disconnect, we'll also update our capabilities to use only 20 MHz on the next connection (if it's on 2.4 GHz) as to avoid the use of the extension channel that has too much noise.

When restarting firmware with an ongoing scheduled scan, we don't (and shouldn't) mark it as aborted as mac80211 will be restarting it, and so no event should go out to userspace. The appropriate comment regarding this wasn't moved to this place, so add it. However, we _do_ need to clean up our internal state, since mac80211 will restart the scan, and we'll otherwise get to the WARN_ON() a few lines below for no reason whatsoever. Signed-off-by:

Some notifications aren't handled by the general RX handler code, due to multi-queue. Add size checks for them explicitly. Signed-off-by:
-
Johannes Berg authored
We shouldn't trust the firmware with the sizes (or contents) of notifications, accessing too much data could cause page faults if the data doesn't fit into the allocated space. This applies more on older NICs where multiple notifications can be in a single RX buffer. Add a general framework for checking a minimum size of any notification in the RX handlers and use it for most. Some RX handlers were already checking and I've moved the checks, some more complex checks I left and made them _NO_SIZE for the RX handlers. Signed-off-by:

We have already WARN_ON(!qc) for non-QOS frame on txq->sched_retry path, but we continue to process, what makes no sense since tid is not initialized. Non QOS frame should never happen when aggregation is enabled on queue, so do not process that. Patch should fix smatch warning: drivers/net/wireless/intel/iwlegacy/4965-mac.c:2822 il4965_hdl_tx() error: uninitialized symbol 'tid'. Reported-by:

We can currently get a "command execute failure 19" error on beacon loss if the signal is weak: wlcore: Beacon loss detected. roles:0xff wlcore: Connection loss work (role_id: 0). ... wlcore: ERROR command execute failure 19 ... WARNING: CPU: 0 PID: 1552 at drivers/net/wireless/ti/wlcore/main.c:803 ... (wl12xx_queue_recovery_work.part.0 [wlcore]) (wl12xx_cmd_role_start_sta [wlcore]) (wl1271_op_bss_info_changed [wlcore]) (ieee80211_prep_connection [mac80211]) Error 19 is defined as CMD_STATUS_WRONG_NESTING from the wlcore firmware, and seems to mean that the firmware no longer wants to see the quirk handling for WLCORE_QUIRK_START_STA_FAILS done. This quirk got added with commit 18eab430 ("wlcore: workaround start_sta problem in wl12xx fw"), and it seems that this already got fixed in the firmware long time ago back in 2012 as wl18xx never had this quirk in place to start with. As we no longer even support firmware that early, to me it seems that it's safe to just drop WLCORE_QUIRK_START_STA_FAILS to fix the error. Looks like earlier firmware got disabled back in 2013 with commit 0e284c07 ("wl12xx: increase minimum singlerole firmware version required"). If it turns out we still need WLCORE_QUIRK_START_STA_FAILS with any firmware that the driver works with, we can simply revert this patch and add extra checks for firmware version used. With this fix wlcore reconnects properly after a beacon loss. Cc: Raz Bouganim <r-bouganim@ti.com> Signed-off-by:

The LTR mechanism enables PCIE Endpoints to report the service latency requirements and CPU will enter appropriate sleep state to save power based on the LTR value. 8723de provides two registers to config the LTR, and the original setting is too short for CPU to ente sleep state.

This ensure that previous association attempts do not leave stale statuses on subsequent attempts. This fixes the WARN_ON(!cr->bss)) from __cfg80211_connect_result() when connecting to an AP after a previous connection failure (e.g. where EAP fails due to incorrect psk but association succeeded). In some scenarios, indeed, brcmf_is_linkup() was reporting a link up event too early due to stale BRCMF_VIF_STATUS_ASSOC_SUCCESS bit, thus reporting to cfg80211 a connection result with a zeroed bssid (vif->profile.bssid is still empty), causing the WARN_ON due to the call to cfg80211_get_bss() with the empty bssid.
