Hi,
we have developed a driver tpm(4) for various TPMs for OpenBSD 4.7 and
FreeBSD 8.0 and have ported and updated several third party packages to
enable use of TPMs on Open- and FreeBSD. This enables applications like
OpenSSH to generate and store private keys inside a TPM.
The supported TPMs are:
- Atmel 97SC3203
- Broadcom BCM0102
- Infineon SLB 9635 TT 1.2
- Intel INTC0102
- Sinosun SNS SSX35
- STM ST19WP18
- Winbond WEC WPCT200
The supported third party packages are:
- openCryptoki 2.3.1: An PKCS#11 implementation, including support
for TPMs. OpenSSH can use this library to generate and store private
RSA keys inside a TPM.
- openssl_tpm_engine 0.4.1: An openssl engine supporting TPMs.
- tpm-emulator 0.7.0: An emulator providing the functionality of a TPM.
Used for development purposes.
- tpm-tools 1.3.5: Various tools for managing a TPM, including key
generation.
- trousers 0.3.5: An implementation of the Trusted Software Stack.
This is the backend libary for the afore mentioned packages.
- trousers testsuite 0.2: A testsuite for trousers.
- TrustedGRUB 1.1.4: An TPM enabled version of grub, including support
for natively booting OpenBSD.
A patch including the driver tpm(4) is attached, more information,
full source code and patches for third party packages can be found at
http://bsssd.sourceforge.net.

My goal is to switch the processor to SMM by triggering SMI from userland.

Re-enabling ACPI module.
Hi, I looked in the new APIC code you commit. The thing that prevent ACPI subsystem from moduler is the way we aquire ACPI root pointer, I think. Right? If so, we can took this in way. 1. Move u_long i386_acpi_root; to machdep.c and madt.c use i386_acpi_root variable, instead of calling AcpiOsGetRootPointer. If Boot loader failed to detect ACPI root pointer, the MADT table is not used, even if the OS can detect it. 2. Re-imprement AcpiOsGetRootPointer so that it does not use AcpiFindRootPointer().

Does anyone work on making ATA moduler?
Hi,There is a problem when PCMCIA related stuff
is used as module, ATA CF is not recognized.
This is because PCMCIA atachment is not compiled
when pccard(4) is not compiled in.
To fix it, we have to supply PCMCIA attachment
in any form.
One way is to make a kernel module that contains only
ATA/PCMCIA attachment with this Makefile
==
.PATH: ${.CURDIR}/../../dev/ata
KMOD= atacard
SRCS= ata-card.c
SRCS+= bus_if.h device_if.h card_if.h power_if.h

Then two question.
1. May I commit this workaround?
2. Are there any people working on ATA for making it fully

unionfs and getcwd problem.
Hi, I had trouble with unionfs when it calles getcwd(3) when I mount some directory on the directry in same file system,like mount -t union /usr/home/foo/bar /usr/src/sys/ . I investigate the problem by inserting debug print in getcwd.c. Then I found issuing __getcwd(2) in getcwd(3) failed, and climb up filesystem tree as the next way. But it failed when it reaches to mount point. It seems that st_dev and st_ino member returns the same number as the underlying filesystem so it failed to recognize mount point. So I tried the patch as follows taken from nullfs. Are there any problem with this patch?

How can I stop HDD or LCD Display ?
Hi, My laptop seems to be transition to S1 sleep. But HDD and LCD did not suspend I think driver or userland program should catch suspend request and send power off request to the devices.

PEACE - Portable Executable win32 API Compatible Environment.
Hi,
I ported kernel part of PEACE from NetBSD.(That is in sys/compat/pecoff/*).
What is PEACE
PEACE is Win32 API Compatible environment for (Originally) NetBSD.
It consist of three parts:
Kernel part to load PE format executable onto process memory space.
Dynamic Linker to link with PE format DLL.
Libraries to translate Win32 API call to NetBSD native system call.
Yes, this scheme is more like BSD/OS's LAP than FreeBSD Linux ABI module.
For more infomation:
http://chiharu.hauN.ORG/peace/
Status:
FreeBSD Specific:
- I ported executable loader moudule to FreeBSD.
- FreeBSD native libraries is not yet available,so I wrote a module to
add(or replace) system call so that the libraries can be run.
- It requires following changes to sys/imgact.h and kern/kern_exec.c to
be able to change size of memory area to hold dynamic linker argument
from executable image loader.

New(bus|pnp)-ifyed joy(4)
Hi, I write patch for joy.c so that it recognize CS4235 Game port by PnP.
API do work,but hardware seems to be uninitialized.
(Read returns only 0x8000)
Are there any person who review this?
To use PnP Interface,
write simply
device joy0
and add your GAME port ID to
joy_ids[];

Re: ISA LM78 driver help

I have an application where I require access to an LM78 health monitor chip on a certain type of industrial PC motherboard we use. Unfortunately, the LM78 is tied to ISA and not I2C/SMBus. Can anyone recommend a good framework to start writing a driver for this beastie? I've never actually written a driver before (*gulp*), so please treat me gently ;-) In essense, the chip sits at 0x290 with an address line at 0x290+5 and a data line at 0x290+6. I'd be happy writing a program that merely peeks and pokes in that address area, rather than a fully-fledged driver... TIA. I have two imprementation about it. One is userland imprementation based on code by Shimizu-san. It is available at http://www.planet.sci.kobe-u.ac.jp/~takawata/smbus/examples/xmbmon104.new.tar.gz And I wrote experimental kernel driver for LM78. http://www.planet.sci.kobe-u.ac.jp/~takawata/smbus/sys/lm-dist.tar.gz Regards, Takanori Watanabe a href=http://www.planet.kobe-u.ac.jp/~takawata/key.html; Public Key/a Key fingerprint = 2C 51 E2 78 2C E1 C5 2D 0F F1 20 A3 11 3A 62 2A To Unsubscribe: send mail to majord...@freebsd.org with unsubscribe freebsd-hackers in the body of the message
