Re: Bad crash with if_bge when loaded as module in loader.conf

 This is 4.7 STABLE from today. It panics when I try to ifconfig
 the bge0 interface.

Wild guess: You have miibus compiled into the kernel and it gets
pulled in a second time when kldloading if_bge?

 In the meantime, is there an easy way to switch over my existing CVS 
 tree to a mirror? (And is there a mirror?)

If you're talking about a working copy, then it's really easy:

find $wcdir -type d -name CVS | while read d; do
sed -i '' s/$oldhost/$newhost/ $d/Root
done

Correct ! I'll look if that solves the crash.

sis 900 10/100BaseTX

2003-02-13 Thread freebsd
I have a laptop (i-buddy) that I have put FreeBSD on.  Everything works great except 
for the NIC.  I think the problem is that freebsd does not have any support for this 
sis card because it is too new.  Anyone know what to do ?  I have included the 
description of the NIC from the web site that I bought the laptop, and the chunk of 
dmesg that has information about the sis card.

(sis discription)
Communications:
Onboard full duplex 10/100 Base-T ethernet, MAC: SiS? 961 built-in
56K / V.90 Conexant PCI software data/fax modem
Built-in SIR transceiver module, IrDA 1.3 standard compliant up to 4.0Mbps

(chunk of dmesg)

 that logs commands may do what they want, but personally I
 think that if you are going to log things then you really want to
 PROPERLY do it, and log the EXEC commands along with the arguments.
 (sadmin et al. doesn't give arguments, and neither does ktrace)

From a security perspective, this is usually referred to as ``indi-
vidual user accountability''; i.e. the ability to hold users compl-
etely accountable for any actions performed under their account.

The notion of ``auditing'' typically goes hand-in-hand with accoun-
tability in this sense.  These are recognised terms in security pu-
blications such as the Information Technology Security Evaluation 
Criteria (ITSEC) [1].

I've been involved in generating a security solution that allowed
the software engineers in the US to remotely connect to a live, op-
erational, safety-related control system in London for the purposes
of fault finding and software deployment.

Before our Independent Safety and Technical Assessors would even
consider looking at such a proposal, we had to provide assurance
that every action by any user logged in remotely would always be
traceable and could be reviewed for audit purposes.

We could only permit remote access to the systems running Tru64 
UNIX as it was the only OS that provided a fully-featured auditing
sub-system that met ITSEC requirements.  Tru64 UNIX will allow you
to log just about any interaction with the system you fancy, from
device access to system calls to command line interaction.

Take a look at Section 10 of Tru64 UNIX Security [2] for more info-
rmation.  If acountability and auditing was to be done properly, I
believe *this* is how it should be done.

I've CC'd [EMAIL PROTECTED] to this post 'cause I
think this would be right up their ally.

Trent.

sis0: MII withour any PHY!


the SiS900 driver has been around for a while. According to the code
if_sis.c's sis_miibus_readreg (redirected from mii.c:^mii_phy_probe)
returns if the phy number is not zero and the SiS900 revision is 
revision 635. I'm going to guess that this might be incorrect for your
chip. Why? Duno.. You could try removing the sc-sis_rev  SIS_REV_635
to see if a phy is on a higher level than zero.
Another option is to check the PCI values. SiS7016 is similar to the 
SiS900, but,
has no internal PHY. Maybe FreeBSD is incorrectly seeing the chip as a 900
when its a 7016? Sometimes that happens if you have an OEM fscking the
PCIDID.

Filesystem Experimentation Question

2003-02-13 Thread Justin Wojdacki

Okay, so I've got an odd ball filesystem idea that I'd like to
experiment with on FreeBSD. 

Looking at it, I can probably best implement it as a layer on top of
FFS at the start, rather than adding a new filesystem driver. 

Does anybody have any recommendations on references to look at for
implementing this? Something like CFS seems like a good starting point
to me, but I'm willing to consider other options (especially ones that
don't break NFS).

NetBSD has overlay filesystems for stackable FS layers. I'm not sure about
FreeBSD, but, its a starting point.

kevent kernel expert.

2003-02-13 Thread Alfred Perlstein
I have come across several (major imo) problems with the kevent(2)
and need to have contact with someone that understands the
implementation, specifically how kqueues are attached to filedesc
structures.

This has to deal with security as well as SMP lock down issues.

Please respond privately.

thank you,
