'RELENG_0_4_0_RELEASE'.

tag

Due to insufficient permission checks in the virtual memory system, a
tracing process (such as a debugger) may be able to modify portions of
the traced process's address space to which the traced process itself
does not have write access.

This error can be exploited to allow unauthorized modification of an
arbitrary file to which the attacker has read access, but not write
access.  Depending on the file and the nature of the modifications,
this can result in privilege escalation.

To exploit this vulnerability, an attacker must be able to run
arbitrary code with user privileges on the target system.

Remove idt because it hasn't been useful since at least 0.3-CURRENT.

Add new ipfw_nat module and prepare for kernel lock manager for nfs w/ rpc.

Also connect uslcom module which we added to the kernel recently.

Major feature merge from FreeBSD 7.1

Introduce FIB (Forward Routing Base) aka multiple routing tables to MidnightBSD.  This is the kernel piece with userland to follow later.

As part of this work, changes had to be made to the vm subsystem, rwlocks introduced, changes to sleep queues, and modifications to the pf firewall.

Effectively this gives us most of the functionality of the FreeBSD 7.1 network stack including tcp offload.

correctly get the number of HPET devices on AMD hardware

Add partial support for Intel Turbo Boost technology on newer i5/i7 and Xeons.

ACPI may report extra level with frequency 1MHz above the nominal to
control Intel Turbo Boost operation. It is not a bug, but feature:
dev.cpu.0.freq_levels: 2934/106000 2933/95000 2800/82000 ...
In this case value 2933 means 2.93GHz, but 2934 means 3.2-3.6GHz.

based on patch by mav @ freebsd

st_atimespec, st_mtimespec, st_birthtimespec etc have been renamed to follow POSIX 2008 specification.

fix null define for GCC

introduce cpuctl interface.  Allows microcode updates or toggling registers on x86 cpus. (amd and intel only)

tag

drop GIANT lock from syslog interface

add sensordev lock to witness list

remove ia64 crap

Sigh... syscons_isa uses these right now

revert previous change and make 4BSD the default sechuler on amd64. This is temporary while we investigate some stability issues

bump MidnightBSD version for support for preinit, init and fini arrays and related chapges to csu and rtld-elf

add missing spin locks.  witness has to know about them

add resize code

deal with various apple partition types

handle the resize case here too.

start work on resize()

add definitions for GRUB2, NetBSD and Apple/Mac OS X

shorten the names of the partition types.  there's a hard limit of 16 characters by convention

partedit makes the assumption that arg0 defines G_PART_PARM_GEOM and G_PART_PARM_PROVIDER).  make that so

rework the pcm lock/unlock logic

drop hfa here too

add sysctl lock protection around register and unregister routines

add some assertions around the sensordev_lock.

Fix botched merge.

add ioctl for 32bit compatibility.

Refactor linux elf/note logic

Get rid of GIANT lock in sensors framework.

I've created a new sensorsdev_lock to protect list operations.  More work might be required in the individual sensor drivers (lm, it, amdtemp, etc).

improve description

mpsafe sysctl

MPSAFE sysctl's.  These happen to be used frequently, especially during make operations.

make sysctl's MPSAFE

make sysctl's mpsafe

Add giant lock around vrele and make all the sysctl's MPSAFE where possible.

Bump for raid5, geom sector changes, new kern.features.inet and kern.features.inet6

expose stripesize and offset

import raid 5 module for geom

add support for midnightbsd slices as well.

Increment MidnightBSD version for libdialog changeover.

use MidnightBSD partition types when possible.

use midnightbsd name

create MidnightBSD GPT partition types rather than FreeBSD on i386/amd64.  Our sparc port isn't much of anything now, and we're still using the FreeBSD VTOC entries as their hack won't work for us as we don't have an ELFOSABI number.

use atomic_store rather than set

Merge rl(4) and re(4) from 7-stable freebsd.

Bring in several improvements to GEOM from FreeBSD 7-stable.

Drop PC98 support from GEOM in MidnightBSD.  We don't support that architecture and it's not worth the effort to maintain.

raid3, label, journal, eli vinum, and part GEOM classes include several bug fixes related to sanity checking, stripe size, disabling debug printing (label), ...

Add sbuf_new_auto macro and clean up some whitespace problems.

Include the parent Makefile.inc

add memmove and initcpu hacks related to vm_guest/virutalization detection.

turn on the new mii stuff in the base kernel

part 2 of the virtualization piece.

Merge several changes from FreeBSD 7-stable.

Introduce virtualization detection.  The kernel knows if it's running with VMWar
e, VirtualBox, Parallels, etc and changes the hz level as well as disables MSI a
s appropriate.  We will need to drop the loader support for part of this once it
's tested further. This is more general and allows us to make more changes for s
pecail hardware emulation.

Update alc(4), bge(4), mii(4) and cardbus as well as pci.  This fixes several pr
oblems with various devices, particularly alc(4) which often had difficulty dete
cting cables were plugged in and DHCP. bge(4) gains support for several newer ch
ips and disables UDP offloading for stability reasons.

We also had to hack zfs so that the kernel memmove can be used now rather than t
he macro bcopy hack.

Introduce some aliases for media types and use them in alc(4).

handle wake on lan link negotiation reset case.

Fix headphone pin config on Lenovo B450 Laptop.

rename several intel chips with the proper family names and add a few missing ones

Add Intel Pather Point support.

Add support for Intel Cougar Point

Hide version in VERBOSE

redo the locking and get rid of the task queue.

Revert zfs related file changes from several days ago. This was a bad idea.

*** empty log message ***

set ssp flags to nothing

Catch up conf/files and conf/files.[i386|amd64]

tweak our build environment for gnu99/c99.

Add the stack protector from FreeBSD.  This relies on a random number generator which is seeded at startup of the kernel (kern/init_main.c, kern/stack_protector.c and sys/kernel.h)

Also introduce qpi which supports workstation chipsets using qpi.   It connects to the nexus and then has pci buses under it.

this directory doesn't exist

sync libalias with FreeBSD 7-stable

Back this change out for now.  I need to turn on c99 for sys first.

Obtained from: FreeBSD 7.3

add atheros ar5416 wireless and amdtemp sensor to NOTES

forgot to commit these

Add driver from DragonFly for Agere gigabit and fast ethernet NICs.

Introduce sysctls for exposing kernel features like PAE, AIO or freebsd 4,5,6 compatibility.

Fix a definition that I missed on a previous commit that was breaking sparc.

Start work on interrupt system.  This code will let one assign an interrupt to a core.

add logic to handle the linux gs register and some additional changes related to cpu affinity.

add gptboot

$MidnightBSD$

Introduce constants for SMAP TYPES. This beats 0x01 randomly in code.

Minor bugfixes to cd9660

perform cleanup on error case.

Supply unique st_dev, st_ino value pair for fstat(2) on pipes.  This is required with sus4 and fixes compatibility problems with several linux centric daemons. This is a port from FreeBSD 10-CURRENT.

Filter out some bad traffic with ipv6 /ipfw.

get rid of invalid use of atomic(9)

don't use stale ip/tcp header pointers

fix typos (from upstream)

add several new device quirks for umass.

Fix module name in zyd, modernize ural

clean this up

change the ati ixp sb600 identifier

Improve error handling.

Add new sound card RDC M3010

revert the detection change on sparc for now.

oops.. i shouldn't have committed this.

GEOM_GPT was renamed GEOM_PART_GPT... forgot to fix it here.

Bump version or cpufreq changes.

td_osd is at the end of struct thread to avoid breaking the ABI
as a side effect it is outside of the td_startzero-td_endzero range,
requiring it to be separately zeroed

cpufreq: allocate long-lived buffer for handling of sysctl
requests.  This stops crazy alloc/free cycle when powerd
is running aggresively.
