* When killing a process, the signal is handled by any thread thatbluhm2019-05-138-41/+59
| | | | | | | | | | does not block the signal. If all threads block the signal, we delivered it to the main thread. This does not conform to POSIX. If any thread unblocks the signal, it should be delivered immediately to this thread. Mark such signals pending at the process instead of a single thread. Then any thread can handle it later. OK kettenis@ guenther@
* Do not check for IFF_RUNNING inside bstp_initialization().mpi2019-05-131-3/+2
| | | | | | | This allows to set such flag after completing the initialization of a bridge and still have bstp_tick() be scheduled from the begining. Fix a regression reported by and ok markus@
* Deal with the case where bridge_getbif() can return NULL.mpi2019-05-131-3/+4
| | | | | | | | Since `bif' are removed from the interface list before calling smr_barrier() and the hash queue is cleaned up afterward, it is possible to find an ifidx with bridge_rtlookup() that won't match to any `bif'. Fix a panic reported by Hrvoje Popovski, ok visa@

| | | | | | | | | | Add a first cut of x86 page table walker to vmd(8) and vmm(4). This function is not used right now but is a building block for future features like HPET, OUTSB and INSB emulation, nested virtualisation support, etc. With help from Mike Larkin ok mlarkin@

* Switch the list of span interfaces and interfaces to SMR.mpi2019-05-123-86/+123
| | | | | | | | | | | | This removes the KERNEL_LOCK() around the list iteration in bridge_enqueue(). Since the NET_LOCK() isn't protecting any data structure, release it early in all the code paths coming from the Network Stack to prevent possible deadlock situations with smr_barrier(). bridge_input() is still KERNEL_LOCK()ed as well as bridge_filterrule(). ok visa@

* Fix 'ifconfig nwflags; These flags ended up overlapping with other flagsstsp2019-05-126-27/+35
| | | | | | | | | | | | in ieee80211com's ic_flags because we haven't been paying attention to them (they're not in the same place in the code and hence easy to miss). Move them to a dedicated variable to avoid this problem in the future. Add a new 'stayauth' nwflag which can be set to let net80211 ignore deauth frames. This can be useful when deauth frames are being persistently spoofed by an attacker. Idea from beck@ ok beck@ phessler@

* Between the broken GIC-500 on the RK3399 and differences in the secure modekettenis2019-05-121-44/+52
| | | | | | | | | | | | | configuration done by TF-A between boards we have to shift the priorities that we use for both the architected ICC_PMR_EL1 register and the memory mapped priority registers on the GIC in different ways. Make this explicit in the code and try to handle all the cases we care about. This includes QEMU and RK3399 boards that still use the TF-A version provided by Rockchip. Seems to make the rockpro64 run stable with a GENERIC kernel. ok drahn@, patrick@

* A trunk(4) usually stays up when the link state of one of its membersflorian2019-05-111-1/+3
| | | | | | | | | changes. While we do get RTM_IFINFO messages for the (physical) member interfaces there is no indication that something changed from the trunk(4) interface. It is helpful to get this information in userland from the trunk so that userland daemons do not need to track interface membership by themselves. OK phessler

While RTF_MPLS is part of RTF_FMASK it should be excluded from the flags and mask when they are applied to the route since toggling it requires a call to rt_mpls_set().

* Add fusbtc(4) to support the Fairchild FUSB302 USB Type-C controller.patrick2019-05-114-3/+699
| | | | | | | | | | | | | | | | A Type-C controller has multiple tasks. Even though the orientation of the plug doesn't matter for the user, it matters for the hardware. To be able to know how to route the SuperSpeed pins you need to know which way the plug is connected. Also you need to know if you're a sink/source or device/host. To get the first connection, you toggle between the modes until you find a connection. In case you see that a sink is connected, you can turn on USB Vbus to power the sink. This driver explicitly does not implement USB's Type-C state machine, but if we get more and more of these controllers it might be worth doing. Also there's no support for Power Delivery messages yet. ok kettenis@
