2021-10-12Remove misleading uvm reference counting that isn't actually used.Mark Kettenis
Make sure uvm_obj_init() is only called once. Call uvm_obj_destroy() when we release the GEM object that wraps an uvm object for which we called uvm_obj_init(). ok mpi@, jsg@

2021-10-12Make our old BSSID available to iwx_newstate_task() when roaming.Stefan Sperling
ic_bss->ni_bssid has already been overwritten once we enter iwx_newstate_task() to perform the state transitions necessary for roaming to our new access point (RUN->AUTH->ASSOC->RUN). We do however use the BSSID in commands sent to firmware. Cache our BSSID in struct iwx_node such that firmware commands keep using the old BSSID while we are still tearing things down. Switch to the new BSSID only once we start back up in iwx_auth(). This should be consistent from the firmware's point of view. Same fix as committed for iwm(4) recently.
2021-10-12Explicitly stop iwx(4) Rx block ack when roaming between access points.Stefan Sperling
This is similar to a recent fix committed to iwm(4). Unlike iwm(4) we do not need to disable Tx aggregation queues in iwx(4). Attempting to do so would cause fatal firmware errors. Tested by jmc@ and myself.
2021-10-12Remove code which was needed to support old firmware images from iwx(4).Stefan Sperling
Tested with cc-a0-63 and QuZ-a0-hr-b0-63 firmware by myself. Tested with Qu-c0-hr-b0-63 firmware by Fredrik Engberg.
2021-10-11Add support for 802.11n 40MHz channels to the iwm(4) driver.Stefan Sperling
According to 11n MCS index tables our maximum data rate is now 300 Mbit/s at MCS 15, excluding protocol overhead. I have measured up to 200Mbit/s of effective throughput on clean 5GHz channels. The driver enables use of 40MHz channels automatically as long as the access point announces support for such channels in its beacons. In case 40MHz transmissions fail we ask firmware to retry with a 20MHz transmission. There is no integration with ifconfig yet, so use of 40MHz is not yet displayed there. In the meantime, tcpdump(8) can be used to check if the current access point supports 40MHz: tcpdump -n -i iwm0 -v -y IEEE802_11_RADIO -s 4096 type mgt and subtype beacon Channel width is displayed in the HT operation information element, where a 40MHz channels looks like this: htop=<40MHz chan X:Y ...> Tested: 7260: florian, bcallah 7265: landry 8260: bket 8265: stsp, abieber, Matthias Schmidt, Josh Rickmar, empee on mastodon 9560: stsp
2021-10-11Add support for 40MHz channels to net80211 RA.Stefan Sperling
For the moment we use either the 40MHz rate set or the 20 MHz one, depending on whether our peer supports 40MHz channels. If this turns out to be suboptimal we could probe the 40MHz and 20MHz rate sets separately to detect which one works better. The same applies to use of the short guard interval (SGI), which is either always on or off at the moment. Again, probing for this could be added later if needed.
2021-10-10Apparently it is possible for firmware to indicate that SMCCC_VERSION isMark Kettenis
implemented but have that call return NOT_SUPPORTED. Makes no sense, but the SMCCC standard documents this and tells us to treat this as v1.0. Change the code accordingly. Turn a few checks that should always be true into KASSERTs to keep the control flow simple. ok patrick@

2021-10-06Allow AUTH->AUTH state transitions in the iwm(4) and iwx(4) drivers again.Stefan Sperling
AUTH->AUTH state transitions happen if the access point uses band-steering. This was originally implemented to fix interop with some Aruba APs, and was probably broken by my recent CVS commit XeKkqPoaUCklmgtC ("prevent attempts to transition towards the same state"). ok mpi@
2021-10-06Make sure iwm(4) uses the HT frame format only for data frames.Stefan Sperling
Non-data frames are not supposed to use HT. This change is for code correctness and does not fix any known issue. And it applies only if the Tx rate has been fixed for testing purposes with a command such as 'ifconfig iwm0 media HT-MCS13 mode 11n'. ok mpi@
2021-10-05Fix iwm(4) performance drop after roaming between APs in 11n mode.Stefan Sperling
Stop BA sessions directly in iwm_run_stop() and disable Tx agg queues when leaving RUN state. Otherwise Tx agg queues do not work properly after switching APs and Tx performance drops to about 2 Mbit/s with excessive retries being reported to RA.

2021-10-04Allegedly a "Marvell Armada 3700 Functional Errata, Guidelines, andMark Kettenis
Restrictions" document exists that discusses an errata #251 in section "3.12 PCIe Completion Timeout" and suggests that setting the DIS_ORD_CHK flag in the Debug Mux Control register is necessary as a workaround: https://lore.kernel.org/linux-pci/20210624222621.4776-6-pali@kernel.org This workaround is still being discussed by the Linux developers, but it does fix an issue I am seeing with athn(4), where an external abort happens under load. So apply this workaround since its potential side effects seem to be significantly less severe than provoking an external abort that hangs the machine. ok patrick@
2021-10-04Build firmware for rsu(4), rtwn(4), and urtwn(4).Kevin Lo
We have to install the files with new filenames (removal of "fw" from each of the filenames) and change the driver to use the new filenames, such that the package becomes irrelevant. Discussed with deraadt@ and sthen@ ok deraadt@
2021-10-04Permission from Realtek to include wireless firmwaresKevin Lo
After deraadt@ explained why the Realtek firmware cannot be put into our tree, I reached out to Realtek to explain the situation. According to the LICENCE.rtlwifi_firmware.txt [1], the rules permitted adding their non-open-source firmware into open source operating systems but such an addition (ironically) makes that open source operating system not entirely open source. Realtek understood the irony, and change the license. Thanks to Realtek for this change which lets us put the firmware .h file into our tree, this means Realtek wireless will work without requiring a firmware download (which is difficult over a non-working Realtek network :) [1] https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/LICENCE.rtlwifi_firmware.txt?id=0f863ff1b388ad5b0f7d25decdbb642#n22 ok deraadt@
2021-10-03Apparently some athn(4) variants are buggy and may hand us corrupt framesMark Kettenis
that are marked "ok". Linux has some workarounds for this and checks whether the status word has error bits set in it regardless of the bit that marks the frame as "ok". Adapt this workaround to our driver and drop the frame after setting input errors. This doesn't filter out all corrupted frames, but it does keep things down to a level where it doesn't fill up the node cache anymore when athn(4) is used in hostap mode. Seen with: athn0 at pci1 dev 0 function 0 "Atheros AR9281" rev 0x01: intx athn0: AR9280 rev 2 (2T2R), ROM rev 16, address xx:xx:xx:xx:xx:xx ok stsp@

2021-09-30In iwm(4) and iwx(4), prevent attemps to transition towards the same stateStefan Sperling
in cases where this would result in a redundant or illegal state transition. jmc@ observed ASSOC -> ASSOC transitions which would result in a hang. Such transitions are invalid and never intentionally triggered by net80211. They imply a race between the Rx interrupt handler and the newstate task. Tested by jmc@ on AX200 for a week and several known issues seem to be fixed.
