this is a step toward deprecating softclock based livelock detection.

2020-06-11Make use of hardware crypto for CCMP. The tricky bits had been lyingjmatthew2-5/+23
dormant in the driver for years, we just needed to insert the IV before transmission and do packet number checks on received frames. tested by kevlo@ solene@ benno@ and me on a variety of hardware ok kevlo@ stsp@
2020-06-08update drm to linux 5.7jsg5-90/+104
adds kernel support for amdgpu: vega20, raven2, renoir, navi10, navi14 inteldrm: icelake, tigerlake Thanks to the OpenBSD Foundation for sponsoring this work, kettenis@ for helping, patrick@ for helping adapt rockchip drm and many developers for testing.
2020-05-29dev/rndvar.h no longer has statistical interfaces (removed during variousderaadt1-3/+1
conversion steps). it only contains kernel prototypes for 4 interfaces, all of which legitimately belong in sys/systm.h, which are already included by all enqueue_randomness() users.
2020-05-25change wsdisplay attribute type from long to uint32_tjsg4-34/+34
miod explained it was initially a long as it was thought drivers may need to allocate storage but in practice they don't need more than 32 bits for an attribute. suggested and reviewed by miod@
2020-05-25rename wsdisplay alloc_attr() to pack_attr()jsg2-12/+12
Suggested by John Carmack. miod agrees a rename would make sense and explained it was initially thought drivers may need to allocate storage but in practice they don't need more than 32 bits for an attribute. ok mpi@
2020-05-23Fix typo in a comment that originated in wpi(4) and has spread elsewhere.stsp1-2/+2
2020-05-17restore VGA fonts on VT switchjsg1-1/+2
Avoids an unusable screen when switching to a VT with a custom VGA font from X. While it is possible to modify the xserver to invoke an ioctl for this kettenis@ points out the xserver may have crashed so doing it in the kernel is preferred. Problem reported by and patch from John Carmack. Changed slightly to do the vga_restore_fonts() (write to video memory) call before vga_setfont() (pointing the character generator at it) at the suggestion of kettenis@. ok kettenis@
2020-05-16Don't attempt to reset the state of the flip-flop associated with thejsg1-7/+1
vga attribute controller index or set the enable/'palette address source' bit when saving and restoring 256 colour vga palette with 0x3c6-0x3c9 as this does not touch the attribute registers. When this code was ported from FreeBSD in vga.c rev 1.48 the flip-flop reset parts were mistakenly made to read 0x3ca instead of 0x3da. Fixes a problem with VirtualBox where the text mode background was a dim red colour instead of black after VT switch. Problem reported by and patch from John Carmack. ok matthieu@ who notes this also fixes a similiar problem with a KVM / virt-manager virtual machine.
2020-05-15Fix CCMP replay check with 11n Rx aggregation and CCMP hardware offloading.stsp1-55/+9
So far, drivers using hardware CCMP decryption were expected to keep the most recently seen CCMP packet number (PN) up-to-date, and to discard frames with lower PNs as replays. A-MPDU subframes may legitimately arrive out of order, and the drivers skipped CCMP replay checking for such frames. Re-ordering happens in ieee80211_inputm(), after the driver is done with a frame. Drivers cannot tell replayed frames apart from legitimate out-of-order retransmissions. To fix this, update the PN value in ieee80211_inputm() after subframes have been reordered into their proper sequence. Drivers still perform replay checks but they no longer have to worry about updating the last seen PN value. The 802.11 spec confirms that replay checking is supposed to happen after A-MPDU re-ordering. Tested by jmc@, benno@, solene@, and myself with the following drivers: athn(4), iwn(4), iwm(4), wpi(4), urtwn(4) ok solene@
2020-05-15Some newer bwfm(4) chips from Cypress hold their regulatorypatrick3-3/+67
constraints in a separate blob, instead of in the firmware. This .clm_blob needs to be loaded as well.
2020-04-30Fix use of uninitialized 'wh' variable in error path of ar5008_rx_process().stsp1-6/+4
This fix simplifies HW decrytion error checking: Frame header contents aren't relevant because we are going to drop frames that had errors in any case. I made a mistake by trying to add an exception for multicast frames at this point. Frame header contents might not even be valid. This problem was introduced with CCMP hardware offload support and detected by Coverity (CID 1492755). ok mestre@ kevlo@
2020-04-29Add the 'nomimo' nwflag which disables MIMO in 11n mode.stsp1-38/+51
This flag restricts a wireless driver to MCS0 - MCS7 for both transmission and reception. It can be set to work around packet loss in 11n mode caused by unused antenna connectors on a MIMO-capable wireless network device. man page tweak from tracey@ ok deraadt@

ok kevlo@ mpi@
2020-04-27Offload CCMP (WPA2) encryption and decryption to athn(4) hardware.stsp3-91/+234
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@

Yet another straightforward ticks-to-milliseconds conversion. I am honestly unsure what particular driver this file belongs to. It seems to be related to pcic(4) and/or pcmcia(4) so I've marked this diff with pcic(4) in the summary line. No complaints on tech@ after six weeks.
