2021-12-07iwlwifi: pcie: retake ownership after resetJohannes Berg4-22/+33
In most cases, unless shutting down the NIC, we really need to retake ownership after doing a software reset of the NIC.

2021-12-07iwlwifi: support 4-bits in MAC step valueMike Golant9-29/+22
We have a MAC component (which is inside the SoC) and it has several different HW steps. 3 bits used to be enough but now we need 4-bits to represent all the different steps. Properly support 4-bits in the MAC step value by refactoring all the current handling of the MAC step/dash. Already from family 8000 and up the dash (bits 0-1) no longer exists and the step (until 8000 bits 2-3) consists of the dash bits as well. To do this remove the CSR_HW_REV_STEP and the CSR_HW_REV_DASH macros, replace them with CSR_HW_REV_STEP_DASH and add hw_rev_step into the trans struct. In addition remove the CSR_HW_IF_CONFIG_REG_MSK_MAC_STEP and CSR_HW_IF_CONFIG_REG_MSK_MAC_DASH macros and create a new macro combining the 2 (this way we don't need shifting or anything else.)

2021-12-07iwlwifi: mvm: synchronize with FW after multicast commandsJohannes Berg1-0/+17
If userspace installs a lot of multicast groups very quickly, then we may run out of command queue space as we send the updates in an asynchronous fashion (due to locking concerns), and the CPU can create them faster than the firmware can process them. This is true even when mac80211 has a work struct that gets scheduled. Fix this by synchronizing with the firmware after sending all those commands - outside of the iteration we can send a synchronous echo command that just has the effect of the CPU waiting for the prior asynchronous commands to finish. This also will cause fewer of the commands to be sent to the firmware overall, because the work will only run once when rescheduled multiple times while it's running.

2021-12-07iwlwifi: mvm: fix delBA vs. NSSN queue sync raceJohannes Berg2-1/+14
If we happen to decide an NSSN queue sync (IWL_MVM_RXQ_NSSN_SYNC) for some remaining packets that are still on the queue, but just after we've decided to do a delBA (which causes its own queues sync with IWL_MVM_RXQ_NOTIF_DEL_BA) we can end up with a sequence of events like this: CPU 1 CPU 2 remove BA session with baid N send IWL_MVM_RXQ_NOTIF_DEL_BA send IWL_MVM_RXQ_NSSN_SYNC get IWL_MVM_RXQ_NOTIF_DEL_BA get IWL_MVM_RXQ_NOTIF_DEL_BA get IWL_MVM_RXQ_NSSN_SYNC complete IWL_MVM_RXQ_NOTIF_DEL_BA remove N from baid_map[] get IWL_MVM_RXQ_NSSN_SYNC WARN_ON(!baid_map[N]) Thus, there's a race that leads in hitting the WARN_ON, but more importantly, it's a race that potentially even results in a new aggregation session getting assigned to baid N. To fix this, remove the WARN_ON() in the NSSN_SYNC case, we can't completely protect against hitting this case, so we shouldn't be warning. However, guard ourselves against BAID reuse by doing yet another round of queue synchronization after the entry is removed from the baid_map, so that it cannot be reused with any in-flight IWL_MVM_RXQ_NSSN_SYNC messages.

2021-11-26iwlwifi: mei: add debugfs hooksEmmanuel Grumbach1-2/+83
Add three debugfs hooks: * status: Check if we have a connection with the CSME firwmare. This hook is a read only. * req_ownership: Send a SAP command to request ownership. This flow should be triggered by iwlwifi (from user space through vendor commands really), but being able to trigger an ownership request from debugfs allows us to request ownership without connecting afterwards. This is an "error" flow that the CSME firmware is designed to handle this way: + Grant ownership since the host asked for it + Wait 3 seconds to let the host connect + If the host didn't connect, take the device back (forcefully). + Don't grant any new ownership request in the following 30 seconds. This debugfs hook allows us to test this flow. * send_start_message: Restart the communication with the CSME firmware from the very beginning. At the very beginning (upon iwlwifi start), iwlmei send a special message: SAP_ME_MSG_START. This hook allows to send it again and this will retrigger the whole flow. It is important to test this restart in the middle of normal operation since it can happen (in case the CSME firmware decided to reset for example).

2021-11-26iwlwifi: mei: add the driver to allow cooperation with CSMEEmmanuel Grumbach11-0/+3749
CSME in two words ----------------- CSME stands for Converged Security and Management Engine. It is a CPU on the chipset and runs a dedicated firmware. AMT (Active Management Technology) is one of the applications that run on that CPU. AMT allows to control the platform remotely. Here is a partial list of the use cases: * View the screen of the plaform, with keyboard and mouse (KVM) * Attach a remote IDE device * Have a serial console to the device * Query the state of the platform * Reset / shut down / boot the platform Networking in CSME ------------------ For those uses cases, CSME's firmware has an embedded network stack and is able to use the network devices of the system: LAN and WLAN. This is thanks to the CSME's firmware WLAN driver. One can add a profile (SSID / key / certificate) to the CSME's OS and CSME will connect to that profile. Then, one can use the WLAN link to access the applications that run on CSME (AMT is one of them). Note that CSME is active during power state and power state transitions. For example, it is possible to have a KVM session open to the system while the system is rebooting and actually configure the BIOS remotely over WLAN thanks to AMT. How all this is related to Linux -------------------------------- In Linux, there is a driver that allows the OS to talk to the CSME firmware, this driver is drivers/misc/mei. This driver advertises a bus that allows other kernel drivers or even user space) to talk to components inside the CSME firmware. In practice, the system advertises a PCI device that allows to send / receive data to / from the CSME firmware. The mei bus drivers in drivers/misc/mei is an abstration on top of this PCI device. The driver being added here is called iwlmei and talks to the WLAN driver inside the CSME firmware through the mei bus driver. Note that the mei bus driver only gives bus services, it doesn't define the content of the communication. Why do we need this driver? -------------------------- CSME uses the same WLAN device that the OS is expecting to see hence we need an arbitration mechanism. This is what iwlmei is in charge of. iwlmei maintains the communication with the CSME firmware's WLAN driver. The language / protocol that is used between the CSME's firmware WLAN driver and iwlmei is OS agnostic and is called SAP which stands for Software Abritration Protocol. With SAP, iwlmei will be able to tell the CSME firmware's WLAN driver: 1) Please give me the device. 2) Please note that the SW/HW rfkill state change. 3) Please note that I am now associated to X. 4) Please note that I received this packet. etc... There are messages that go the opposite direction as well: 1) Please note that AMT is en/disable. 2) Please note that I believe the OS is broken and hence I'll take the device *now*, whether you like it or not, to make sure that connectivity is preserved. 3) Please note that I am willing to give the device if the OS needs it. 4) Please give me any packet that is sent on UDP / TCP on IP address XX.XX.XX.XX and an port ZZ. 5) Please send this packet. etc... Please check drivers/net/wireless/intel/iwlwifi/mei/sap.h for the full protocol specification. Arbitration is not the only purpose of iwlmei and SAP. SAP also allows to maintain the AMT's functionality even when the OS owns the device. To connect to AMT, one needs to initiate an HTTP connection to port 16992. iwlmei will listen to the Rx path and forward (through SAP) to the CSME firmware the data it got. Then, the embedded HTTP server in the chipset will reply to the request and send a SAP notification to ask iwlmei to send the reply. This way, AMT running on the CSME can still work. In practice this means that all the use cases quoted above (KVM, remote IDE device, etc...) will work even when the OS uses the WLAN device. How to disable all this? --------------------------- iwlmei won't be able to do anything if the CSME's networking stack is not enabled. By default, CSME's networking stack is disabled (this is a BIOS setting). In case the CSME's networking stack is disabled, iwlwifi will just get access to the device because there is no contention with any other actor and, hence, no arbitration is needed. In this patch, I only add the iwlmei driver. Integration with iwlwifi will be implemented in the next one.

This was suggested by Arend v7: * fix a locking issue in case of CSME firmware reset: When the CSME firmware resets, we need to unregister the netdev, first take the mutex, and only then, rely on it being taken. * Add a comment to explain why it is ok to have static variables (iwlmei can't have more than a single instance). * Add a define for 26 + 8 + 8 * Add a define SEND_SAP_MAX_WAIT_ITERATION * make struct const * Reword a bit the Kconfig help message * Ayala added her Signed-off * fixed an RCU annotation v8: do not require ownership upfront, use NIC_OWNER instead.

In some very rare cases the init flow may fail. In many cases, this is recoverable, so we can retry. Implement a loop to retry two more times after the first attempt failed. This can happen in two different situations, namely during probe and during mac80211 start. For the first case, a simple loop is enough. For the second case, we need to add a flag to prevent mac80211 from trying to restart it as well, leaving full control with the driver.
