Proposal: MAC_BIBA and real-world usage
Hello,
Are there many people actually using the MAC subsystem in the real
world? I have been working to set up a shared hosting webserver and
I've stumbled against some limitations with the BIBA policy.
In short, it's an excellent model, and can be used succesfully if
applications are aware of its existance, but I find it incompatible
with the real-world needs in Unix, and,

MAC problems
FreeBSD version: 5.1-RELEASE
Hi,
I'm quite new to FreeBSD. I've check list archives and
read a handbook, but I didn't find solution to my problem
and I hope this is not off-topic.
I've installed 5.1-RELEASE, enabled ACLs on the filesystems
and I wanted to test MAC features. I'm also new to MAC, so
perhaps this is some my mistake.
When I enable mac_biba or mac_lomac (in

mac_bsdextended log information
Hey everyone,
I'm hoping someone can point me in the right direction. I'm running a 6.1 box with mac_bsdextended compiled. I've created my ugidfw rules, and all seems well in the universe.
I've got rules set up so the web process uid 80 and gid 80 can only read uid 1010 and gid 1010 owned files. When the web server tries to do something else, it throws an error such as:

Errors in the FreeBSD handbook (MAC framework)
(crossposted to freebsd-security just in case someone has to slap me) :)
Hello,
I'm doing some work with the MAC subsystem in FreeBSD, and I have
spotted some errors in the MAC documentation in the handbook.
1- Section 15.14.4. Error in the example dropping users "nagios" and
"www" into the insecure class. The example uses the command "pw

Questions about MAC
FreeBSD 5.1-RELEASE
Hi,
I'm examining Biba and MLS MAC policies and something is
not clear for me. Unless I'm doing something wrong,
it seems policies are enforced only for reading, but
not writing.
1) Biba
I've created test file with biba/127 label:
$ echo "Message" > file_biba_127.txt
$ setfmac biba/127 file_biba_127.txt
$ getfmac file_biba_127.txt

Trusted Path Execution
I would like to know that there is or is not a way to prevent users from
executing binaries that are not owned by root or that the user is in a
particular group. Is this something I can achieve with TrustedBSD's MAC
framework?

Starting X11 with kernel secure level greater than -1/0.
Hi, is there any chance (if yes, how to do this?) to use the xf86
driver which "provides access to the memory and I/O ports of a
VGA board and to the PCI configuration registers for use by
the X servers when running with a kernel security level greater
than 0" in FreeBSD*?
Then it will be possible to start X environment with a kernel
secure level > 0, right? Normally it is impossible

mac questions: stopping root from reading /home && mac_biba stops clean shutdown
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
I just try to understand the concepts and possiblities behind the mac
framework. After days of puzzling I found one puzzling behaviour and
still have one immediate question (this is on 5-stable)
- - when I enable mac_biba, set root to biba/equal (or any value,
actually), and do a setfmac -R biba/equal / I expect biba to be

Cluster analysis

I have no idea if this question is to easy to be answered, but I?m starting
with R. So, here we go.
I have a large dataset with a lot of steps a judicial case. A sample is

I?d like to do a cluster analysis to try to understand with one is the most
usual path followed by this legal cases.
After that, I?d like to plot a cluster tree.

5.1-R-p2 crashes on SMP with AMI RAID and Intel 1000/Pro
Dear Sirs.
It seems to me a never ending story. We run a box with a TYAN Thunder
2500 Dual SMP mainboard, 2GB ECC Tyan certified memory, AMI Enterprise
1600 RAID adapter and additional Intel 1000/Pro server type (64 bit)
GBit LAN NIC. With FreeBSD 4.8 this was stable, but to achive this
state was really hard! It is a story similar to that what happend when
we changed towards FreeBSD

[LLVMdev] Issue with Machine Verifier and earlyclobber
Hello Jakob,
I'm still getting the error, I can give you any other debug info you need.
I haven't pasted the regalloc debug info here because it is quite huge, but
if you tell me what specific details you need I will include them.
Thanks for your help!

stub actions that depend on the parameter
Hi,
I''m pretty new to all related to bdd and rspec and I have the following
question. Is it possible to stub actions that return different objects
depending on the parameteres they were called with? Something like this:
MyClass.stub!(:method).with(1).and_return(@mock_object_1)
MyClass.stub!(:method).with(2).and_return(@mock_object_2)

Jakob, one more hint, I've placed some asserts around the code you added
and noticed that the InlineSpiller::insertReload() function is not being
called.

It's not likely I'll have time to look at this in the near future. I'd recommend you do it yourself.

[LLVMdev] LLVM ERROR: ran out of registers during register allocation
Ok, I've found that marking tiny live intervals as not spillable inside
VirtRegAuxInfo::CalculateWeightAndHint is not playing nicely with very
constrained regclasses, in my case a regclass composed of only one
register.
As a workaround, instead of marking them as not spillable, I've marked them
with a very high spill cost and the regalloc is able to compile the
function with good code

[LLVMdev] Original data type after DAG legalization
Hello,
Is there a way to determine before register allocation if a virtual reg is
mapped to the lo or hi part of a piece of a value? Basically i need to tell
the register allocator to use a certain set of registers for the lo part and
others for the hi part, so in order to do this i would have to know if the
data value was expanded into smaller pieces and which piece is each one.
Additionally,
