Let in a program a variable 'x' is tainted. There is an assignment 'y=x' where y is untainted. How to check the taintflow in the output or data flow graph ? Any suggestions? Thank you. Have a great day. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20190912/5bb3655c/attachment.html>

Hello, Some time ago, I noticed that whilst I had upgraded to Xen 3.1 (kernel 2.6.18-xen), I''d forgot to upgrade the paravirt DomU .cfg kernels from 2.6.16-xen to reflect this. So, I upgraded the DomU kernels & ran into issues with mounting devices, and the ext3 module not being available. After a bit of faffing about, I managed to sort this out and load the ext3 module.

CentOS Community, Would someone who is familiar with reading boot messages and kernel errors be able to assist with advising me on what the following errors might mean in dmesg. It seems to come up randomly towards the end of the logfile. ------------[ cut here ]------------ WARNING: at arch/x86/kernel/cpu/mtrr/generic.c:467 generic_get_mtrr+0x11e/0x140() (Not tainted) Hardware name: empty

I have a machine with a recent install of centos (2.6.32-220.2.1.el6.x86_64 kernel). It crashed 3 times this week, and sent emails like the one below complaining about kernel taint. I've gone back to a previous kernel to see if that helps, but otherwise I don't know how to investigate this. What should I do? Here's stuff from the log and one of the emails:

Hi all, I am having problems to get the SeaLevel IO card to work with CentOS distro. Basically the card is being recognised and shown by lspci BUT /proc/devices file is not updated with the new devices does anyone know why. ? Could someone tell me what/where infos are needed to get /proc/devices to be updated. The reason I require the /proc/devices infos is because I want to run a mknod

I used the xensource install script for RHEL4 and after trying to boot on the new kernel the system just continually rebooted. I appended a noreboot to the xen line and now i''m seeing the following...

hi all, I am searching the taint analysis tool on Xen, which can taint the memory at byte level. Is there any tools on Xen? or any patches? Thanks.

Hi I hope this is the right mailing list to ask some questions related to the llvm. I am new to llvm and I decided to use llvm to conduct static analysis of the linux kernel( mostly on the TCP/IP stack). One thing is that whether llvm support static taint analysis. Could you please give me some examples if you have or do I have to implement it by myself. If so, any suggestions available? My

CentOS Experts, I am receiving the following in /var/spool/mail/root. I cleaned out the file and then rebooted and the same errors came back. Is it possible to analyze the data and advise if there is an issue with my system? This is a completely fresh install.

Hi, The klee library directory is determined at compile time and cannot be changed afterwards. Have a look at tools/klee/main.cpp to see how it is computed. I usually use Klee without any install step, right from the build directory. This has never given me the error you see. Hope this helps, Jonas On Wed, Jun 5, 2013 at 5:26 PM, Alexandru Ionut Diaconescu < alexandruionutdiaconescu at
