* deprecate interface input handler lists, just use one input function.dlg2020-07-221-12/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | the interface input handler lists were originally set up to help us during the intial mpsafe network stack work. at the time not all the virtual ethernet interfaces (vlan, svlan, bridge, trunk, etc) were mpsafe, so we wanted a way to avoid them by default, and only take the kernel lock hit when they were specifically enabled on the interface. since then, they have been fixed up to be mpsafe. i could leave the list in place, but it has some semantic problems. because virtual interfaces filter packets based on the order they were attached to the parent interface, you can get packets taken away in surprising ways, especially when you reboot and netstart does something different to what you did by hand. by hardcoding the order that things like vlan and bridge get to look at packets, we can document the behaviour and get consistency. it also means we can get rid of a use of SRPs which were difficult to replace with SMRs. the interface input handler list is an SRPL, which we would like to deprecate. it turns out that you can sleep during stack processing, which you're not supposed to do with SRPs or SMRs, but SRPs are a lot more forgiving and it worked. lastly, it turns out that this code is faster than the input list handling, so lots of winning all around. special thanks to hrvoje popovski and aaron bieber for testing. this has been in snaps as part of a larger diff for over a week.

* uvideo_querycap(): Set the 'device_caps' field of struct v4l2_capability like done in utvfu(4)landry2020-07-051-2/+3
| | | | | | | | | | | | | | | | | | Fixes webcam detection in firefox 78, where code was added to check for V4L2_CAP_VIDEO_CAPTURE capability on 'device_caps', whereas we only set it in the 'capabilities' field. According to https://www.kernel.org/doc/html/v4.14/media/uapi/v4l/vidioc-querycap.html#description those distinct fields are here for drivers that provide several devices, but firefox decided to check for 'device_caps' field instead of 'capability' (cf https://hg.mozilla.org/integration/autoland/rev/33facf191f23) - so fill the field for compatibility reasons, while https://bugzilla.mozilla.org/show_bug.cgi?id=1650572 discusses with upstream what's the right way. ok mglocker@

* kernel: use gettime(9)/getuptime(9) in lieu of time_second(9)/time_uptime(9)cheloha2020-06-241-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | time_second(9) and time_uptime(9) are widely used in the kernel to quickly get the system UTC or system uptime as a time_t. However, time_t is 64-bit everywhere, so it is not generally safe to use them on 32-bit platforms: you have a split-read problem if your hardware cannot perform atomic 64-bit reads. This patch replaces time_second(9) with gettime(9), a safer successor interface, throughout the kernel. Similarly, time_uptime(9) is replaced with getuptime(9). There is a performance cost on 32-bit platforms in exchange for eliminating the split-read problem: instead of two register reads you now have a lockless read loop to pull the values from the timehands. This is really not *too* bad in the grand scheme of things, but compared to what we were doing before it is several times slower. There is no performance cost on 64-bit (__LP64__) platforms. With input from visa@, dlg@, and tedu@. Several bugs squashed by visa@. ok kettenis@
* Acknowledge xhci(4) interrupts before calling usb_schedsoftintr().patrick2020-06-241-5/+5
| | | | | | | | | | | | | | | | | On powerdown (halt -p), sd(4)'s suspend function tries to powerdown a USB mass storage using a STOP command. In that case we are already cold and splhigh(), so that the xhci is supposed to run in polling- mode. usb_schedsoftintr() behaves differently when running in polling-mode. Instead of scheduling a soft interrupt, it immediately dequeues from the event queue. But dequeueing means touching the xhci registers. Apparently we need to acknowledge the interrupts before touching those registers, the hardware doesn't like it otherwise and we will never get an interrupt status for the second transfer. ok gerhard@
* Apply sc->sc_xfer_flags to control transfers as well. These are usedpatrick2020-06-241-5/+5
| | | | | | | | | | so that in polled-mode the USB transfers are marked synchronous. In case that sending commands to the USB mass storage fails, the control transfers are used to reset the device. Without the synchronous flag, the STOP command sent by sd(4) on powerdown would wait for completion indefinitely, possibly hanging the machine. ok gerhard@

* Release the rx node if we were unable to allocate a new rx buffer.jmatthew2020-06-161-2/+2

| | | | | | | There's no reliable way to decide whether a control must belong to "inputs" or to "record". In other words both classes were used for the same thing. Furthermore we've no "play" class which tends to make things more confusing.

* Offload CCMP (WPA2) encryption and decryption to athn(4) hardware.stsp2020-04-272-6/+59
| | | | | | | | | | | | | | | | This reduces CPU load during traffic bursts, which is especially noticeable on boards with relatively slow CPUs such as Alix and APU. For reference, my rcc-ve boards (Intel Atom C2558) now forward ~2000pps between Ethernet and wifi with <= 1% CPU interrupt time according to systat. Beforehand, these boards became noticeably less responsive with fairly high interrupt and spin %. CCMP offload is used on both PCI and USB devices (thanks kevlo@ for catching my omission of USB devices in the first iteration of this change!) Tested by (at least) Kevin Chadwick, tracey@, kevlo@, kili@, Ted Patterson, David Dahlberg, and Scott Bennett. ok tracey@ kevlo@
