remaining instances of them with appropriate copy(9) usage.
ok art@, tested on all arches unless my memory is non-ECC
|
|
Instead of allocating a static amount of memory for the data
structures via valloc() in allocsys(), allocate things dynamically
using pool(9) when possible and malloc(9) when not. The various
members of struct seminfo and struct shminfo are in kern.seminfo
and kern.shminfo respectively (not all members of kern.seminfo are
changable).
The data structures used still leave something to be desired but
things are not made worse in that respect by this commit.

produce typo fixes, but the typo pool is infinite.

altq is merged into pf and handled through pf.

In sys_sigreturn - don't uvm_useracc the context address and then copyin
it afterwards. The copyin deals better with finding if the user address is
correct and it's faster.

breaks i386:setup_buffers() because of this.

instead of the pa. Most callers already had it handy and those who didn't
only called it for managed pages and were outside time-critical code.
This will allow us to make those functions clean and fast on sparc and
sparc64 letting us to avoid unnecessary cache flushes.
deraadt@ miod@ drahn@ ok.

to allow access to VGA card's memory by mmapping /dev/xf86.
The macdep.allowaperture does also control /dev/pci access.
Ok miod@, deraadt@

Instead of using FOE for just emulating references, we also keep track
of a pages executability and don't remove the FOE bit if the page
is not executable.
This is implmented with horrible hacks. Maybe when I have time, I'll
reimplment the whole pmap to allow this without ugly hacks (read: probably
not this decade).
The stack on alpha is now non-exec.

an uvm aobj, copy out the signal trampoline into it and share that page
among all processes for the same emulation.
This also requires us to actually be able to tell signal code where the
trampoline is located, so introduce a new field in struct proc - p_sigcode
that is a pointer to sigcode. This allows us to remove all the ugly
calculations of the signal trampoline address done in every sendsig
function in the tree (that's why so many files are changed).
Tested by various people. ok deraadt@

Added to floppy31 still fits.

We kept too much of the old code in trap handling.
This should fix floppies and bsd.rd on some machines.
|
|
squashed already.
|
|
usage of cdev_decl() in the driver code is more tricky since i have
kqueue mods here and there and will fix that on that way through.
|
|
|
|
wrong than using cdev_decl_random for the same purpose
|
|
|

|
|
And yes, they are different macros with different results.
|
|
In most cases we'll have either DDB or /dev/ksyms and if someone
really needs the memory they'll strip the kernel.
Fixes alpha/2705.

to treat the 'addr' the same way on all archs. This means that alpha can't do anything with the
addr because we need a complete trap frame to be able to print a trace.

that specifies which printf funciton it should use. Implement
db_stack_trace_cmd in MI code.
Thanks to miod@ for all the tests.
|

Tested by various people on various platforms, I'm willing to fix any
breakage this causes.
ok niels@ deraadt@ and mickey@ (after his comments were applied)

we'll use for printing the information.
miod@ ok

Without this, n_type in struct nlist ends up as N_UNDF for those
symbols which makes vmstat -i unhappy.
mido@ OK
|
|
A few local changes and tweaks remain.
This bring DEC 3000 machines back in the game, but framebuffers are still
not supported at the moment.
Thanks to ericj@ and nate@ for supplying me a DEC 3000 for testing.

FP_C (Floating Point Control Quadword).
From ross@NetBSD. Added a way to disable it with option NO_IEEE,
which appears on the ramdisks to save space. This affects only
programs compiled with -mieee, and what it essentially does is
enabling infinities and NaNs, instead of generating SIGFPE on
division by zero, overflow, etc.

your kernel configuration file.
By default, GENERIC will enable this.
When PTRACE is not enabled, several ptrace-like features of the procfs
filesystem will be disabled as well (namely, the ability to read and write
any process' registers, as well as attching, single stepping and detaching
to/from processes).
This should help paranoid people build better sandboxens, and us to build
smaller ramdisks.

More or less directly from FreeBSD.

The patch allows you to change the value of NMBCLUSTERS, BUFCACHEPERCENT
and NKMEMPAGES using the config command, instead of recompiling the kernel.
This is the kernel part of the patch. I have compiled it on i386, sparc64,
alpha and macppc. -moj ok art@ maja@
