2016-01-04Record the modified mbuf chain after transmit checksum setup codeMike Belopuhov
Keep the modified chain pointer and pass it back to the calling code so that it will get properly accounted for. Change it to m_pullup since m_pulldown with a zero offset is just as good. Tested by yasuoka@, myself and mxb at alumni ! chalmers ! se, thanks! ok yasuoka, mpi

2016-01-04Add initial support for 11n mode to the iwn(4) driver.Stefan Sperling
Only MCS 0 to 7 are supported for now. Tested by many. There might still be outstanding issues but they now appear to be rare. I'm putting this in so that additional fixes can be developed and tested more easily if required. This diff is already quite large for one commit. ok deraadt
2016-01-04Replace magic shifts and bitmasks used for ADDBA parametersStefan Sperling

2016-01-04ADDBA frames have a parameter set which we check against our own capabilitiesStefan Sperling
but we were checking bits in these parameters with the wrong set of bitmasks. Negotiating A-MPDUs with some APs failed because of this bug. ok kettenis@

2016-01-04Don't return 11n mode from ieee80211_chan2mode() so we can switch intoStefan Sperling
11a and 11b/g mode correctly when the driver supports 11n. And make sure the result of this funtion is only used to index ic_sup_rates. Its stated purpose is to help select a legacy rate. ok sthen jasper kettenis deraadt mpi

2016-01-04Do proper termination of VMs by doing proper VCPU run state management.Mike Larkin
This should fix some of the odd termination errors people have been seeing (vmctl status showing running VMs after they have exited/crashed, and invalid instruction panics on vmptrld during certain races) This diff also implements dropping the biglock when running a VCPU, and reacquiring the lock as needed based on the type of exit (normal vs. external interrupt) diff supplied by Stefan Kempf <sn.kempf at t-online.de>, many thanks!

2016-01-02Take the PHY of iec(4) out of reset before attaching the interface.Visa Hankala
Otherwise the PHY goes undetected on the slave node of a dual-node Origin 200. The PHY gets enabled by diagnostic checks but only on the master node. As the attach code will now do the enabling, the checks can be disabled on reboot, making reboots faster especially on IP27. Tested on Origin 200 (IP27), Fuel (IP35 with iec), and Origin 350 (IP35 without iec). Diff from miod@, ok krw@
2016-01-02mmcc noticed that nd.ni_pledge was uninitialized in doopenat() for theTheo de Raadt
oflags & 3 == 3 case. Therefore this depends on vn_open() blocking the operation later. Probably this meant the ni_pledge request would be too high, causing transient operation failure, rather than transient operation passage). Instead of initializing based on the oflags value use the result of FFLAGS(). I should have done this from the start. ok semarie [oflags & 3 == 3 is major dejavu for me]
2016-01-01The pointer buf is a user space string which was directly passedAlexander Bluhm
to tputchar() and could crash the kernel. Better use cnwrite() in sendsyslog2() for writing to console. It takes a struct uio which does the copyin() automatically. In addition cnwrite() outputs to the real console or to a redirected one, whichever is appropriate. One drawback is that the syslog priority cannot be stripped off easily. OK deraadt@
2016-01-01Sync formatting and a few comments with upstream. No functional change.Ingo Feinerer
2016-01-01Reimplement vga_put() such that it compiles on i386 as well.Mark Kettenis
2016-01-01Sync V4L2 header file with upstream (i.e., recent Linux kernel) headers.Ingo Feinerer
This syncs our videoio.h with upstream videodev2.h and inlines their v4l2-controls.h (which was split off from videodev2.h). Another header, v4l2-common.h, is currently not imported as it is GPL2 licensed. There will be a second commit just addressing whitespace and formatting. The current version has only real changes whereas the second commit will bring videoio.h in line with videodev2.h formatting so that potential syncs in the future are easier to implement.

kernel lock in the rx and tx path anymore. While there seems to be a small decrease in forwarding performance with our default network stack settings, Performance whiel receiving manymore packets than we can handle is better.

2015-12-31Add pchtemp(4) a driver for the thermal sensor on recent Intel PCHs.Mark Kettenis
2015-12-31Provide a minimal implementation of the Linux vga_get/vga_put API and use itMark Kettenis
in inteldrm(4). The Intel integrated graphics device has a major design flaw where it needs legacy VGA io access to disable VGA mode completely. This only works if legacy VGA io routing is setup such that it actually reaches the IGD. This typically isn't the case if the primary VGA device is a discrete graphics device. To make sure we don't whack that device we have to temporarily route legacy VGA io access to the IGD. Fixes the "black screen" issue reported by Timo Myrra and others.

2015-12-29Set UltraDMA transfer mode. Some (early?) SATA drives, such as the MaxtorMark Kettenis
7Y250M0, refuse to do DMA unless the transfer mode has been set. This causes reads (and presumably writes) to time out. Unlike the wdc code, this only sets the UltraDMA transfer mode. If we ever want to support ancient PATA drivers through the atascsi layer, we probably need to set the PIO and/or MWDMA transfer modes as well. ok jmatthew@, dlg@)
