2020-06-22The interface if_ioctl routine must be called with the NET_LOCK() held.Claudio Jeker
For example the bridge_ioctl() function calls NET_UNLOCK() unconditionally and so calling if_ioctl() without netlock will trigger an assert because of not holding the netlock. Make sure the ioctl handlers are called with the netlock held and drop the lock for the wg(4) specific ioctls in the wg_ioctl handler. This fixes a panic in bridge_ioctl() triggered by ifconfig(8) issuing a SIOCGWG ioctl against bridge(4). This is just a workaround this needs more cleanup but at least this way the panic can not be triggered anymore. OK stsp@, tested by semarie@

2020-06-22Fix two iwx(4) TX_CMD_OFFLD macros.Stefan Sperling
The IP_HDR and MH_SIZE fields represent byte offsets into the frame, rather than flags. Make these macros require a parameter to prevent them from being misunderstood as flag bits. In iwlwifi these are defined via an enum, with most values being used as parameters to BIT(). Yet these IP and MH ones are actually used to shift length values to particular positions within the offloading parameters of the Tx command. Fortunately, these macros aren't used yet in our version of the driver.
2020-06-22Prepare for newer iwx(4) firmware scan command versions.Stefan Sperling
Add declarations of "version 2" scan flags from iwlwifi and prepare the iwx_scan_channel_cfg_umac struct for life beyond version 1. None of this is needed yet. But we will need this at some point and I've already written the diff, hoping it would prevent firmware errors (which of course it didn't).
2020-06-22Update definition of the iwx_ac_to_tx_fifo map.Stefan Sperling
Compared to iwm(4) devices the BE and BK fifo numbers have been swapped in iwx(4) hardware. This has no real consequences for us since we send all frames at the same access category, but I'm fixing the mapping anyway.
2020-06-22Enable critical temperature detection in iwx(4) firmware.Stefan Sperling
The driver will turn the device off and print a message to dmesg if the firmware signals critical temperature. It looks like the firmware will also make use of a Tx-backoff mechanism to regulate device temperature.
2020-06-22Do not copy an SSID into the iwx(4) probe request template.Stefan Sperling
Firmware will add SSIDs specified via the scan command to its probe requests. There is no need to copy an SSID into the template. This code path is not used yet because active scanning mode is still disabled in this driver.
2020-06-22Fix unconditional write to v1.scan_priority in iwx(4) scan command.Stefan Sperling
The data structure for the scan command contains a union which represents various versions of the scan command. The driver wrote to the scan_priority field in version 1 data regardless of the scan command version actually expected by firmware. Perform that write only for scan command version 1, as intended. Testing suggests that this prevents occasional firmware errors during scans.

2020-06-22a first cut at requesting and parsing vpd info.David Gwynne
reading vpd stuff is useful when you're trying to get support information about a pci device, eg, if you want a serial number, or firmware versions, or specific part name or number, it's likely available via vpd. also, im sick of having the diff in my tree. this relies on the new PCIOCGETVPD ioctl i just committed to the kernel. it's a very quick and dirty implementation, hopefully someone will pick it up and polish it a bit. tested by hrvoje popovski on a variety of cards ok jmatthew@

2020-06-22let userland read vpd info from a pci device.David Gwynne
reading vpd stuff is useful when you're trying to get support information about a pci device, eg, if you want a serial number, or firmware versions, or specific part name or number, it's likely available via vpd. also, im sick of having the diff in my tree. the vpd info is not accessed as bytes read from a capability, but is read via a register in the capability. the same register also supports updating or writing vpd info, which sounds like a bad idea to let userland have raw access to. this adds an ioctl so that userland can ask the kernel to read via the vpd register on its behalf. this ensures that the only access is read access, and it's sanity checked. tested by hrvoje popovski on many devices. ok jmatthew@
2020-06-22deprecate network livelock detection using the softclock.David Gwynne
livelock detection used to rely on code running at softnet blocking the softclock handling at a lower interrupt priority level. if the hard clock interrupt count diverged from one kept by a timeout, we assumed the network stack was doing too much work and we should apply backpressure to the receptions of packets. the network stack doesnt really block timeouts from firing anymore though. this is especially true on MP systems, because timeouts fire on cpu0 and the nettq thread could be somewhere else entirely. this means network activity doesn't make the softclock lose ticks, which means we aren't scaling rx ring activity like we think we are. the alternative way to detect livelock is when a driver queues packets for the stack to process, if there's too many packets built up then the input routine return value tells the driver to slow down. this enables finer grained livelock detection too. the rx ring accounting is done per rx ring, and each rx ring is tied to a specific nettq. if one of them is going too fast it shouldn't affect the others. the tick based detection was done system wide and punished all the drivers. ive converted all the drivers to the new mechanism. let's see how we go with it. jmatthew@ confirms rings still shrink, so some backpressure is being applied.

2020-06-21vmd(8): fix ns8250 lockup due to race conditionpd
Inject a pending interrupt even if the rcv_pending flag is set to avoid the endless EV_READ loop where a byte lingers read to be read but the vcpu never gets the interrupt to read it. (e.g. the result of spamming RETURN via the serial console) Also, protect com ratelimit handler with mutexes to avoid corruption of the device state. These changes help preventing linux vm crashes when the return key is held on boot. Discovered by and patch from Dave Voutila <dave@sisu.io> ok tb@
