Permissive devices in Xen
Hello, is there any reason why even permissive devices cannot write some areas in the PCI config space? The PCI_COMMAND is handled in special way so that the device is enabled/disabled properly, am I right? Why is PCI_INTERRUPT_LINE read from dev->irq and not from the config space? Why the PCI address bars are handled in very different way? And it seems that writing these bars is never

InfiniBand device in Xen
Hello, I''m trying to get working infiniband device in Xen. I have Xen v3 with 2.6.18 kernel. I export PCI device from Dom0 into DomU. I''ve enabled permisive device in Dom0. However, inserting infiniband module results in the following messages (with little more verbosity which I have added): pcifront pci-0: Installing PCI frontend pcifront pci-0: Creating PCI Frontend Bus

Re: NUMA issues on virtualized hosts
Hello, ok, I found that cpu pinning was wrong, so I corrected it to be 1:1. The issue with iozone remains the same. The spec is running, however, it runs slower than 1-NUMA case. The corrected XML looks like follows: <cpu mode='host-passthrough'><topology sockets='8' cores='4' threads='1'/><numa><cell cpus='0-3'

PCI device export
Hello, I''m trying to get to work InfiniBand card in DomU via exporting PCI device. How does the export works internally? I guess that pci frontend forwards stuff like pci_read_config_dword and pci_write_config_dword to pci backend that actually does it. Am I right? So if the driver of InfiniBand writes some config values to PCI config space and these values are not applied actually,

ipportfw - security
Hi Are there any known security holes or necessary precautions in using port forwarding with ipportfw? I'm planning on forwarding ports from an outer firewall/router (connected to the Internet) to a host in the DMZ, then on from the DMZ host to the inner firewall, and finally from the inner firewall to some host on the inside. Thanks, Jens jph@strengur.is From mail@mail.redhat.com Wed

OpenSSH and Heimdal KRB5
Has anyone have patches to allow OpenSSH to use Heimdal Kerberos? I suspect the patches <http://www.ics.muni.cz/scb/devel/heimdal.html> against SSH 1.2 could likely be easily adapted for use with OpenSSH. Has anyone already done this? I'm willing to test and may, if time permits, even do the port of the above patches. Kurt

SSHD does not cleanup kerberos ticket while root logins
Hi all, It looks like a bug for me, but I'd like to ask if someone has the same problem. We are using OpenSSH 4.3p2 from Debian 4.0 (stable), but the same problem is with original OpenSSH 4.3p2. When root logins with his kerberos ticket and then logout, his ticket remains on the machine. I found in source (sshd.c) in privsep_postauth function, that if root logins then use_privsep is set to 0

SSH security hole found
>From http://lwn.net/#security A vulnerability present in the SSH software package can allow an attacker to execute arbitrary commands on the SSH server. To protect against this, immediately upgrade to ssh 1.2.25. Red Hat ssh-1.2.25 RPMs are available, as is the Debian ssh-1.1.25 package for hamm (Debian 2.0-to-be). There are SSH 1.2.25 RPMs here:

variance?,...
hi I'm learning R and making some examples. One of them is that for given distribution I show density function, distribution function expected value and variance(?). I know EX <- function(xval,xprob) sum( (xval*xprob) ); where xval is vector of values and xprob vector of probabalities, but DX <- function(xval,xprob) EX((xval^2),xprob) - (EX(xval,xprob))^2; doesn't work as I

openssh (fwd)
Some people on the OpenSSH list have expressed an interest in Kerberos version 5 support. Below is a (non-US) URL recently posted for a patch to OpenSSH to work with Heimdal, the international K5 implementation. I haven't checked to see if the patch would work with MIT or MIT-derived K5 libraries. -- Mike Fisk, RADIANT Team, Network Engineering Group, Los Alamos National Lab See
