* Ensure that link-local addresses are correctly configured on loopbackmpi2015-01-274-88/+42
| | | | | | | | | | | | | | | | | | | | interfaces. When the kernel automagically configures IPv6 addresses on loopback interfaces, start by assigning a link-local address and then try to assign "::1". Only the first configured loopback interface per rdomain can have the "::1" address. But even if other loopback interfaces failed to get this address, because it is already taken, give them a chance to have a link-local address. While here change in6_ifattach() to return an error value and remove duplicated code. Fix a regression introduced by the NOINET6 flag removal. ok henning@, stsp@, florian@, benno@

* remove the second void * argument on tasks.dlg2015-01-2751-269/+257
| | | | | | | | | | | | | | | | | | | | | when workqs were introduced, we provided a second argument so you could pass a thing and some context to work on it in. there were very few things that took advantage of the second argument, so when i introduced pools i suggested removing it. since tasks were meant to replace workqs, it was requested that we keep the second argument to make porting from workqs to tasks easier. now that workqs are gone, i had a look at the use of the second argument again and found only one good use of it (vdsp(4) on sparc64 if you're interested) and a tiny handful of questionable uses. the vast majority of tasks only used a single argument. i have since modified all tasks that used two args to only use one, so now we can remove the second argument. so this is a mechanical change. all tasks only passed NULL as their second argument, so we can just remove it. ok krw@

This breaks compatibility with initial static pie binaries and requires a recent user-land prior to upgrading. In addition, more fine grained errors can be returned from execve(2) when errors occur while attempting to execute ELF objects. okay guenther@, kettenis@, deraadt@

| | | | | | | devino into a pseudo-sysino, directly use the devino as the ihandle. The devhandle is stored in the cbus softc, and accessed through the bus space tag. This allows us to have more than 256 interrupts on a single cbus, and avoids relying on the lower bits of the devhandle being zero.

* refactor loading of dmamaps.dlg2015-01-251-173/+77
| | | | | | | | | | | | | | | | | | | | | | | | | | bus_dmama_load and bus_dmamap_load mbuf figure out the physical addresses of the memory theyre given and then hand it to _bus_dmamap_load_paddr to store in the dmamaps sg lists. unfortunately bus_dmamap_load_mbuf assumes it is only given memory from the kernels direct mapped region, and blindly translates anything its given into phys addresses to hand to _load_paddr. i recently committed change to pool asking them to allocate large pages, which meant uvm allocated mbufs outside the direct map, which meant bus_dmamap_load_mbuf was handing out bogus physical addresses. the pool change got backed out until i could debug this. now _load and _load_mbuf now call _bus_dmamap_load_vaddr for every buffer theyve been given, which properly determines if the addresses are in the direct map or via the tlb. _load_vaddr then feeds the physical addresses into _bus_dmamap_load_paddr to store them in the dmamap. tldr; _load_mbuf doesnt make naive assumptions about its addresses now. ok miod@ kettenis@

* move from deferring vd requests with a task per message to a ringdlg2015-01-231-39/+59
| | | | | | | | | | | | | | of pointers to vd requests, and a single task to notify the taskq that there's work on the ring. the ring is modelled on what you usually get with network cards, which is an array with a producer and consumer index. the interrupt handler fills an entry in the ring at the producers index and increments it. the task reads entries at the consumer index and increments it until it reaches the same value as the producer. tested and slightly tweaked by kettenis@ ok kettenis@
