2016-02-05Fix iwn(4) CCMP replay detection so it does not drop out-of-order A-MPDUStefan Sperling
subframes. Helps 11n mode with WPA. tested by me, tb@, and krw@
2016-02-05Count A-MPDU subframes with sequence number below the current BA window asStefan Sperling
duplicates rather than input errors. These subframes have either already been received, or the window was moved by the gap timeout which should only happen with buggy APs. Neither condition indicates a severe problem. Perhaps we will introduce a separate counter for this later.
2016-02-05Guard against integer overflow when checking whetherStefan Kempf
writing to a file on msdosfs stays within the max. file size. ok kettenis@, krw@
2016-02-05Define EDCA tables for 11n mode. Per 802.11-2012 they are the same asStefan Sperling
the tables for 11a/11g modes. Add a function to append a Microsoft WME parameter element to a frame, using EDCA tables to construct the parameter records. Some 11n AP's I have observed provide this element. None of this code is used yet, so no functional change. I wrote this while debugging BlockAck and then realized it was only needed for hostap mode. Once we support 11n in hostap mode and send A-MPDUs, this code will be needed.
2016-02-05In iwn(4), set max A-MPDU length to 64k instead of 4k and tell the firmwareStefan Sperling
about A-MPDU spacing. Makes BlockAck happy. tested by me, tb@, krw@, sthen@, and Henrik Friedrichsen
2016-02-05In iwm(4), set max A-MPDU length to 64k instead of 4k and tell the firmwareStefan Sperling
about A-MPDU spacing. Makes BlockAck happy. tested by myself and abieber@
2016-02-05Store ADDBA request and response parameters in the block ack record ofStefan Sperling
ieee80211_node. This way, we can keep track of the ACK policy and echo it back to the AP as required by the standard. And use the correct bit flag for the policy -- this code was confused between BlockAck and ADDBA, both of which have a policy bit but in different places. Fixes apple airport APs. tested by tb@, krw@, sthen@, abieber@, and Henrik Friedrichsen

2016-02-04Some (buggy) UEFI implementations don't report the correct framebufferMark Kettenis
parameters unless SetMode() has been called, even if we don't actually change the mode. Other (equally buggy) UEFI implementations report an error if we call SetMode() but don't actually change the mode. Work around these issues by always calling SetMode() (like we did before rev 1.10), but don't report an error if the current mode is the same as the desired mode. ok yasuoka@
2016-02-04If the ROM size is 0, we won't be able to read the video BIOS from it.Mark Kettenis
Bail out early to prevent a panic from calling bus_space_map(9) with size 0.
2016-02-03Do not access the scsi link of the disk at the beginning of sdopen()Alexander Bluhm
and sdminphys() if the scsi disk is dying. The memory of the link may have been freed already. OK krw@
2016-02-03When accessing the scsi link of a scsi disk, use a variable "sc_link"Alexander Bluhm
everywhere. This is the first step to fix a use after free of the sc_link when the disk detaches. If a function gets a scsi transfer, the scsi link is always valid. Call this variable "link" consistently. OK krw@
2016-02-03Increase the RPC buffer once more to 4096 bytes. The guestinfo.ovfEnvReyk Floeter
mechanism is used to configure VMs in the VMware vSphere world: instead of using individual key-value guestinfo.* properties, it uses the guestinfo.ovfEnv value to pass an enterprise-compliant XML file that includes key-value properties. This file can be rather large, especially with comments, but 4k ought to be enough for anybody. Also change a stack buffer to malloc'ed memory in the ioctl path. OK mikeb@
2016-02-03Prevent efifb(4) from attaching if we're the console.Mark Kettenis
Unfortunately, making this decision in radeondrm_attachhook() is too late because at that point efifb(4) would have already been attached. This means that if we decide to bail in radeondrm_attachhook() we may end up without a glass console. That may happen for example if the firmware package has not been installed. I'm still looking for a solution for that problem. ok jsg@

2016-02-02A few reliability improvements in the power management interfaceMike Belopuhov
Nathanael Rensen <nathanael at list ! polymorpheus ! com> came up with a few improvements to the event watcher and power management interface, namely: o Make sure to put our watcher on a list before issuing an XS_WATCH command since Xen will raise the event right after it's been set up. o The first time xen_control is called the "control/shutdown" node may not exist, so skip printing the error message in this case. o Acknowledge requests by writing back an empty string. o log(9) reboot and halt requests like vmt(4) does. Huge thanks!

2016-02-01move to -release modeJonathan Gray
requested by deraadt@
2016-02-01Stop requiring a BlockAck session timeout. We still honour the timeout ifStefan Sperling
the AP requests it, though I don't think I've ever seen one that does. Per the 802.11-2012 spec a value of zero disables the timeout and some APs seem to have trouble with timeouts forced onto them. Our behaviour now matches Linux in this regard. This gets Apple Airport APs somewhat working in 11n mode but there is still a remaining issue with receiving frames from them. Doesn't seem to hurt any other APs I've tried. ok sthen@ mpi@ millert@

2016-01-31Don't use sxitimer on Allwinner sun7i/A20.Jonathan Gray
sxitimer isn't generating hardclock ticks on Allwinner A20. Fortunately the Cortex A7 based Allwinner A20 has the ARM Generic Timer (agtimer) available so use that. To allow this to work sxirtc gets it's own mapping instead of using a subregion of sxitimer. From Patrick Wildt.
2016-01-31Leonardo Guardati discovered a u-boot built with "Enable workarounds forJonathan Gray
booting old kernels" was required to boot sunxi kernels with newer versions of u-boot. Unless built with OLD_SUNXI_KERNEL_COMPAT u-boot now uses the top four bits of the board id for a 'compatibility revision'. This was supposedly for different handling of the pll5 dram clock, but we don't touch that currently. Mask these bits away so the kernel will boot from a u-boot that doesn't have the option set. Tested by Patrick Wildt on a Banana Pi R1 with current u-boot sources.
