2012-03-20Add ioctl to write to hypervisor memory.Mark Kettenis
2012-03-19On sgi, use CKSEG0 addresses whenever possible for pmap_map_direct and u areaMiod Vallat
pages. This will allow R5000-based systems with physical memory fitting in CKSEG0 to use 16KB pages and direct maps (since only XKPHYS accesses trigger the XKPHYS coherency errata on these processors). Tested on IP32, IP30 and IP27 (and loongson too as well).
2012-03-19Recent uvm code (and maybe not-so-recent, but it did not explode^WKASSERT atMiod Vallat
my face then...) depends upon PMAP_PREFER_ALIGN to be a power of two, minus one. On mips64 with 4KB pages, the runtime variable used to compute PMAP_PREFER_ALIGN had the low PAGE_SHIFT bits zeroed (for no good reason I'd say). Don't bother zeroing them anymore.
2012-03-19Use uncached addresses for all exception vectors, when copying our code (orMiod Vallat
trampolines) to them; this makes sure there is no risk of pending writes being lost when we clear the caches. Of course, this would be a bug in the cache handling routines, but having our vectors correctly set will help debugging the issue. Tested on sgi and loongson.
2012-03-19Change the page size computation logic to default to 16KB pages, and onlyMiod Vallat
restrict to 4KB if the kernel is configured with R5000 or RM7000 family support. Allow the kernel configuration to override this if it knows better (e.g. an upcoming kernel configuration with support for R5000, but where physical memory on R5000 systems fits within the first 512MB).
2012-03-19Prevent the Ethernet driver to be opened twice when using a bootp() path;Miod Vallat
some ARCBios don't like this.
2012-03-19Teach the bootblocks how to load kernel from tftp (i.e. when OSLoadPartitionMiod Vallat
is bootp() instead of a disk). Kind of ugly because of the usual `can't seek' problem causing kernels with symbols to be read from the network twice. While there, add a 32 bit ECOFF boot block, not hooked to the build yet, to be used shortly.
2012-03-19Only change the default boot device to a bootable softraid volume, if weJoel Sing
are able to handle the given discipline. At this stage amd64 boot(8) is limited to RAID 1. This makes life easier for users who are booting from a softraid crypto volume, but are loading a kernel from hd0a:/bsd. Tested by jrick@devio.us - thanks!

2012-03-15Fix vmmap SMALL_KERNEL introduced bug.Ariane van der Steldt
The if (min < VMMAP_MIN_ADDR) min = VMMAP_MIN_ADDR; code should have moved across when the small_kernel diff moved the initialization from uvm_map_setup() to uvm_map_setup_md(). Prevents a nasty panic on hppa, sparc64 (and possibly other archs). kettenis: the diff make some sense to me
2012-03-15Take cd9660 support off the "obviously a floppy" install media, to findTheo de Raadt
new space. The same cannot be done yet with some other architectures which share the RAMDISK kernel amongst media types too tightly. I am investigating the horrific src/distrib cleanups required to fix that.
2012-03-15uncached_base was introduced early in IP27 support, since these designs useMiod Vallat
subspaces in the CCA_NC uncached memory space. However, being coherent, there was never a need for bus_dma to use uncached addresses. This means that, on the only systems where uncached_base was not set to PHYS_TO_XKPHYS(0, CCA_NC), it was never used. Remove the variable, and replace PHYS_TO_UNCACHED() with PHYS_TO_XKPHYS(, CCA_NC). No functional change.
2012-03-15No longer allow bus_space_barrier() to be a NULL pointer on a givenMiod Vallat
bus_space_tag on sgi, but rather always provide at least a dummy asm("sync") flavour. Saves a function pointer test at runtime.
2012-03-15Allow multiple backslashes at the start of a namespace path. It is prettyMark Kettenis
clear this is not supposed to happen, but unfortunately the description of the ECDT table in the standard document has a path that starts with two backslashes so that's what some vendors used. From Christophe Staiesse. ok deraadt@
2012-03-15Reduce installmedia pressure from new vmmap.Ariane van der Steldt
Has less special allocators on install media (where they aren't required anyway). Bonus: makes the vmmap initialization code easier to read.
2012-03-15improve IPsec/ENC interaction:Markus Friedl
- ipip_input() recalculate the IP header checksum if the tos bits are changed after decapsulation. Otherwise these packets are dropped later in the stack. - ip_ecn_egress(): do not drop packets for IPsec if the outter packet of a Tunnel has the ECN-CE bit set (Congestion Experienced) and the inner packet does not indicate support ECN. - remove unused ip6_ecn_ingress(), ip6_ecn_egress() code ok mikeb@

2012-03-14Close a race that would corrupt a sockbuf because the code that externalizesMark Kettenis
an SCM_RIGHTS message may sleep. Bits and pieces from NetBSD with some simplifications by yours truly. Fixes the "receive 1" panic seen by many. ok guenther@, claudio@
2012-03-14ubsec gets stuck after receiving a packet of a particular lengthMike Belopuhov
and stops processing any further packets. this is believed to be a result of the inconsistency of the destination mbuf chain as a a copy acquired via m_copym2 works fine. so far only one problem was discovered with the optimized inline version of m_copym2: a cluster has to be allocated if source chain had one. unfortunately, this solves the problem only for some packet sizes so apply a larger hammer and call m_copym2 for now. the problem was reported and diffs were patiently tested by Joosep <joosepm-at-gmail-dot-com>, thanks! deraadt agrees to this temporary measure.

2012-03-09New vmmap implementation.Ariane van der Steldt
no oks (it is really a pain to review properly) extensively tested, I'm confident it'll be stable 'now is the time' from several icb inhabitants Diff provides: - ability to specify different allocators for different regions/maps - a simpler implementation of the current allocator - currently in compatibility mode: it will generate similar addresses as the old allocator
