2014-04-20emc on my cx500 works as well as rdac on all my rebadged engenio kit.David Gwynne
2014-04-18Have each thread keeps its own (counted!) reference to the process's ucredsPhilip Guenther
to avoid possible use-after-free references when swapping ids in threaded processes. "Do I have the right creds?" checks are always made with the threads creds. Inspired by FreeBSD and NetBSD "right time" deraadt@

2014-04-04If the PDC_COPROC call fails, and we are running on a PA 1.1 system, assumeMiod Vallat
the usual 1.1 coprocessor mask, instead of using zero and having every userland process dying with signal 4. The circumstances under which this call fails are unclear and could be tied to specific PROM version (I have tried overzealous stack alignment and other tricks, to no avail). Interestingly enough, the 715/75 system which hits this problem, only triggers it when booting from disk, and never when booting from network. This diff is an ugly bandaid until the problem is better understood. Or maybe it is not worth investigating, seeing that Linux hardcodes the coprocessor mask and never issues PDC_COPROC calls; I wonder what HP/UX does. In my tree for over 18 months; "Looks like a nice hack" deraadt@ 715/75 system provided by Sebastiaan Indesteege, thanks!

2014-03-29It's been a quarter century: we can assume volatile is present with that name.Philip Guenther
ok dlg@ mpi@ deraadt@
2014-03-28enable mpath plus sym and rdac on some archs so we can learn about whatDavid Gwynne
the effects will be. sgi will follow after i fix some known fallout first.
2014-03-26Move p_emul and p_sigcode from proc to process.Philip Guenther
Tweak the handling of ktrace EMUL when changing ktracing: only generate one per process (not one per thread) and pass the correct proc pointer down to the VFS layer. Permit generating of NAMI and CSW records inside ktrace(2) itself. ok deraadt@ millert@

2014-03-19It's safe to assumed 'signed' existsPhilip Guenther
2014-03-16DDB supports ELF symbols are all archs, and it's always the same as thePhilip Guenther
native size, so eliminate the #defines. ok miod@
2014-03-13get rid of the assumption that the head of the alldevs list is theDavid Gwynne
"mainbus" device. this breaks when mpath is enabled because it attaches before mainbus and therefore takes the head position. have autoconf provide device_mainbus() which looks up mainbus_cd, and use that instead. discussed with deraadt who just wants mpath stuff to move forward despite there being many ways to shine this particular turd.
2014-03-12enable qla(4) and qle(4) in GENERIC configs where isp(4) is alreadyJonathan Matthew
2014-03-11lint is gone, and the 'lint' conditional was never in the implementationPhilip Guenther
namespace, so stop changing behavior when it's #defined ok beck@ krw@
2014-03-08No reason to leave hppa behind.Mark Kettenis
2014-02-19add qla and qle everywhere we currently have isp, commented out except forJonathan Matthew
qle in GENERIC on i386, amd64 and sparc64, where it's reasonably well tested and likely to be useful. requested by deraadt@ and kettenis@, ok dlg@
2014-02-08Use extent_alloc_with_descr(9) and add a mutex to protect the extent.Mark Kettenis
This should make bus_dmamap_load(9) and bus_dmamap_unload(9) "mpsafe".
2014-01-30Move declaration of struct vm_page_md from <machine/vmparam.h> toMiod Vallat
<machine/pmap.h> where it belongs, and compensate in <uvm/uvm_extern.h> by including <uvm/uvm_pmap.h> before <uvm/uvm_page.h>. Tested on all MACHINE_ARCH but amd64 and i386 (and hppa64).
2014-01-30To prevent lock ordering problems with the kernel lock, we need to make sureMark Kettenis
we block all interrupts that can grab the kernel lock. The simplest way to achieve this is to make sure mutexes always raise the ipl to the highest level that has interrupts that grab the kernel lock. This will allow us to have "mpsafe" interrupt handlers at lower priority levels. No change for non-MULTIPROCESSOR kernels. Tested by juanfra@
2014-01-24Do not protect struct vm_page_md with defined(_KERNEL), for userland uvmMiod Vallat
grovellers need to know it to be able to get the right size for struct vm_page.

use a MD-supplied random function. Then, insert this into the ELF openbsd.randomdata of the kernel, so that it has entropy right from the start. Some help from jsing for the softraid aspects. Also tested by phessler

2013-10-19Use daddr_t * instead of int * for the partoffp parameter toKenneth R Westerback
readdoslabel(). Ditto all the MD variables whose addresses are passed to readdoslabel() via partoffp. Fix some 512-byte block vs disk sector confusion in hppa and sgi. All the DL_GETxxxxx() defines return disk sector values. All DL_SETxxxx() take disk sector values. These changes should be no-ops until a drive using non-512-byte-sectors is encountered. ok deraadt@
2013-10-17Remove support for a.out and ecoff. We only do elf now.Theo de Raadt
ok miod
2013-10-15We do not produce "core" files, so they do not need to be deleted. theyTheo de Raadt
have been *.core files for a very long time. That's a lot of unlink() calls saved.
2013-10-15Rewrite the awk script that generates the data for option DDB_STRUCT:Philip Guenther
- switch to perl for better data structures and (thus) speed - fix a couple glitches in the interpretation of the stabs output - compress the strings by putting them in one big array and overlaying suffixes - all sizes and offsets are <64k, so use u_short for them This results in ~60% reduction in the resulting text size and it now takes less than a second to create on fast platforms. ok miod@
