the assembly code in libcrypto assumes unaligned access is allowed for ARMv7. Make these paths conditional on __STRICT_ALIGNMENT not being defined and define __STRICT_ALIGNMENT in arm_arch.h for OpenBSD. ok tom@

This extern variable appears not to be used. And it is overridden by local variable in doConnection(). This causes MSVC warning C4459 "declaration of 'verify_error' hides global declaration". OK millert@

2018-01-06Fix an interrupt storm condition in vldcp(8) (sparc64).stsp1-1/+9
If the Rx channel goes down with pending data on the ring, toss the pending data to ensure that the firmware's rx ring head index matches the rx ring tail index. Otherwise we trigger an interrupt storm since vldcpread() never consumes pending data while the channel is down, and the firmware keeps triggering the interrupt until all data on the ring is consumed. Interrupt storm observed and fix tested on a T5220 (which can now run ldom guests; without this fix starting ldomd would trigger the problem). ok kettenis@

2018-01-06pckbd: don't change translation mode if controller is in table 2jcs1-5/+13
This was changed a decade ago to forcibly try table 3 first in order to make some now-long-gone hardware work. Newer Lenovo machines seem to have trouble being asked to change modes which manifests as a long boot delay as it waits for each request to timeout, or by causing the keyboard to generate junk when typing. Assume table 2 by default and just leave it alone if it's already there. This is how Linux has operated for quite a while and seems to help on these Lenovo machines. Tested by a few with these machines and has been in snaps for a bit.

2018-01-06rework the transmit and receive paths to address reliability issues.dlg2-341/+266
phessler@ has been having trouble with msk on overdrive 1000s. some of the issues relate to the driver not coping with exhaustion of mbufs for the rx ring, the other issues are corruption of the mcl9k pool that msk uses. this diff adds a timeout that the rx refill code uses when the rx ring is empty and cannot be filled. it'll periodically retry the ring refill until it can get some mbufs in the air again. the current code made hunting for the mcl9k issue too hard, so this rewrites it to be simpler and more like other drivers. there's now just arrays of mbuf pointers and dmamaps to shadow the hardware ring entries, and producer and consumer indexes. what was there before had linkes lists of something to hold mbuf pointers and dmamaps, and some way to go from the ring to go back to that. i think, it was hard to tell what was happening. this also copies the ADDR64 handling on the tx ring to the rx ring. this potentially makes more rx descriptors available, but that can happen later. in hindsight the mcl9k problem could have been from letting if_rxr allocate the entier ring. if every descriptor was filled, the chip may have run around the ring when it shouldnt have. giving rxr one less descriptor than there is on the ring may have fixed the problem too. this work also makes it easier to make msk mpsafe. tested by an ok phessler@ ok kettenis@ deraadt@
2018-01-05To send out packets we need to create a flowring. Acting as station,patrick3-17/+189
we typically have about four flowrings per priority. As access point we apparently need one, or four considering the priorities, flowrings per client. For now let's start with a single TX flowring. To setup a flowring we need to send a create request and can only start sending packets as soon as we are told that the ring is created. With this we can now do actual network traffic.
2018-01-05Drop incoming network packets as long as we are not in RUN state. Thispatrick1-2/+11
happens when we successfully associate and the AP tries to initiate the WPA2 handshake but we haven't received the asynchronous ASSOC event yet. Dropping the packet will make the AP retry, and at that point we should have successfully associated. While there, don't feed the event packets to our network stack. It's been helpful for debugging but now it's time to let go.

2018-01-05When we receive an AUTH or ASSOC event even though we have alreadypatrick1-3/+11
reached the RUN state, this probably means that we have roamed to a different AP. In that case throw us back into SCAN mode and let the stack look for a new AP to connect to. In the future it might be worthwhile to use the ROAM event information to read the new AP information to adjust our stack, but that is further down the road.
