2011-07-19Warn about but don't prevent installboot from installing /boot whenKenneth R Westerback
the OpenBSD partition starts at >128G. This restores previous behaviour but adds the warning. ok deraadt@ guenther@

2011-07-08When reading dos labels use DOS_LABELSECTOR and don't use LABELOFFSET. For ↵Kenneth R Westerback
all these arch's LABELSECTOR == DOS_LABELSECTOR == 1, and LABELOFFSET == 0. Thus, to quote bob, "This is a no-op". Makes the expression used when writing label the same as the one used in readdoslabel().

2011-07-07The drahn memorial bad kernel build fix: prevent blood pressurePhilip Guenthe
spikes in other developers by making it so that removal of a .d file without removing the corresponding object will result in the latter being treated as out of date. ok beck@ art@ drahn@
2011-07-07There is a bunch of places in the kernel entry points where we don'tArtur Grabowski
hold the kernel lock, but still need call one function that needs it. Instead of grabbing the lock all over the place, move the locks into the affected functions: trapsignal, scdebug*, ktrsyscall, ktrsysret, systrace_redirect and ADDUPROF. In the cases we already hold the biglock we'll just recurse. kettenis@, beck@ ok
2011-07-07Replace the cruddy old sys/net/zlib.[ch]. We now use the sys/lib/libzTheo de Raadt
code. Missing chunks of the API are imported from the libc version, with a few #ifdef's to port it into the kernel environment. The bootblocks already used the newer code, and should encounter no surprises since there are so few changes to the existing files. In the kernel, ipcomp and kernel ppp are changed to the new API. ipcomp has been tested. ok tedu the brave

delete.
2011-07-05Don't write /boot to sector 0 on non-floppy devices. Non-floppyKenneth R Westerback
devices must have an OpenBSD MBR partition to install /boot into. But search anything except floppy devices (e.g. vnd) for such a partition. Feedback & ok deraadt@
2011-07-05More non-512-byte sector groundwork. Don't let disklabel hint thatKenneth R Westerback
a ffs frag size can be less than the d_secsize of the disk. Make sure amd64 writedisklabel() puts the disklabel where readdoslabel() will read it. Tweak i386/amd64 installboot/biosboot so sectors are indeed used where sectors are claimed. Lets me fdisk, newfs, mount and installboot onto 2048 and 4096 byte sector devices. Other filesystem utilites will still hold surprises. Note that actually booting from such devices will await BIOSen that acknowledge such devices as bootable. ok guenther@
2011-07-05N: Thou shalt not call hardclock() with biglock held.Owain Ainsworth
i386 disobeys the Nth commandment. Fix this. While here, make i386 and amd64 definitions of iplclock and statclock match. ok art@, kettenis@

2011-07-05Recommit the reverted sigacts change now that the NFS use-after-freePhilip Guenthe
problem has been tracked down. This fixes the sharing of the signal handling state: shared bits go in sigacts, per-rthread bits goes in struct proc. ok deraadt@

2011-07-04Force the sigreturn syscall to return to userspace via iretq by settingPhilip Guenthe
the MDP_IRET flag in md_proc, then switch sigcode to enter the kernel via syscall instead of int$80. Rearrange the return paths in both the sysretq and iretq paths to reduce how long interrupts are blocked and shave instructions. ok kettenis@, extra testing krw@

2011-07-04Let custom nlist.c check ELF, but use the i386 values EM_I386 andKenneth R Westerback
ELFCLASS32 since we are building a 32-bit executable. Which is why we have a custom nlist.c here. Suggested by drahn@. ok drahn@ "looks good" deraadt@

2011-06-27Ensure we don't re-issue a failed buf without clearing B_ERROR andKenneth R Westerback
b_error. Otherwise a good i/o will appear to have failed. Fixes problem with dkcsum.c being unable to read data to checksum from subsequent devices after an i/o fails. And thus failing to find correct root in some cases. Introduced at k2k11 with buf flags rectification. Scan of all biowait() calls finds no other obvious re-use of a buf that could have error'ed out. Just re-use of bufs that worked. So quick fix pending closer review of all uses. Problem noted by Jens A. Griepen. ok matthew@ deraadt@

From Brad.
2011-06-16Raise the number of interrupt sources per CPU from 32 to 64. This effectivelyMark Kettenis
triples the number of interrupt vectors that can be handled by the primary CPU. Important for MSI, but could also fix some issues with large machines loaded with a lot of devices. tested by many; ok deraadt@, marco@
2011-06-05Move the bufcachepercent setting code to MI locations -- set it to 42%Theo de Raadt
for now; that is unlikely to hit some of the remaining starvation bugs. Repair the bufpages calculation too; i386 was doing it ahead of time (incorrectly) and then re-calculating it. ok thib

2011-05-30Remove the freelist member from vm_physsegOwain Ainsworth
The new world order of pmemrange makes this data completely redundant (being dealt with by the pmemrange constraints instead). Remove all code that messes with the freelist. While touching every caller of uvm_page_physload() anyway, add the flags argument to all callers (all but one is 0 and that one already used PHYSLOAD_DEVICE) and remove the macro magic to allow callers to continue without it. Should shrink the code a bit, as well. matthew@ pointed out some mistakes i'd made. ``freelist death, I like. Ok.' ariane@ `I agree with the general direction, go ahead and i'll fix any fallout shortly'' miod@ (68k 88k and vax i could not check would build)
