2020-05-17restore VGA fonts on VT switchJonathan Gray
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@

2020-05-16Fix PHY_CONTEXT commands sent to iwx(4) firmware.Stefan Sperling
iwx(4) firmware understands two different variants of these commands. Both variants are documented with the same command API version number, but they use different sizes for an embedded struct which contains information about channels. Which variant to use depends on whether the firmware advertises support for the "ULTRA_HB_CHANNELS" feature. The code I wrote to handle both cases had a bug in case this feature is not supported: The channel info size difference was only accounted for while computing the command's length, but not while writing command data. This bug does not affect devices presently matched by iwx(4). But it is possible that other devices may need this fix in the future. So, for now, fix the buggy code path instead of removing it. ok mpi@
2020-05-16Don't attempt to reset the state of the flip-flop associated with theJonathan Gray
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.Stefan Sperling
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@

2020-05-15Explain enqueue_randomness() better. It is the supply-entropy function,Theo de Raadt
and change wording from 'entropy queue', what we have is a ring which collects 'damage' from successive calls until drawn down
2020-05-15The long explanation for CRC stirring isn't helping. If anythingTheo de Raadt
it suggests we should reconsider this mechanism and do something simpler... delete the explanation for now.
2020-05-15The main comment block from 1996 has become highly inaccurate andTheo de Raadt
misleading, so rewrite it. The interesting parts are bootblock-seeding from file + hwrng, arc4random() being available incredibly early, and seperate timeouts to pull entropy data forward into a stir of the chacha state (one for entropy ring crc whitening into a buffer, the 2nd for buffer folding into the chacha) Now that it is better documented, I can try to improve each component.

block ack notifications sent by iwn(4) firmware"). This effectively reverts changes in how the driver interacts with firmware and fixes connections getting stuck for unknown reasons, in two known cases: One with an Airport Extreme 6th gen AP and another with a b-box 3V+ modem using a Sagemcom MAC address for its built-in AP. The Sagemcom case was observed by myself. The Airport case was reported by Jeremy O'Brien via abieber@.

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.

2020-04-30Fix use of uninitialized 'wh' variable in error path of ar5008_rx_process().Stefan Sperling
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@
