A security vulnerability in the Linux kernels 2.4.22 - 2.4.25 and 2.6.1 - 2.6.3 has been announced. It was found around 6 months ago, and has been fixed in the 2.4.26 and 2.6.4 kernels. Anyone using the affected versions are advised to upgrade to newer kernels.

About the vulnerability: The vulnerable code is in net/ipv4/ip_sockglue.c:ip_setsockopt(), an integer overflow bug. The MCAST_MSFILTER option can trigger this vulnerability.

We've been trying to use bigmem versions of kernel on our RH 7.2 systems (running only apache), but under high level of traffic kscand hogs the CPU. We've upgraded to bigmem version of 2.4.30-9 and we're still seeing this issue. When we start httpd with moderate load (200-400 simutaneous connections) kscand/HighMem would eat up all the CPU every few seconds. The system load averags from 5 to 10. If we stop httpd the load would go back down. For the same amount of traffic, the non-bigmem kernel has the average load of 0.5.

Hi,

I am trying to install RH9 on a HP ze4115; everything seems to work fine except X won't work. The error is "No screens" while XF86config appears ok. I know others have run into this and some claim to have solved it (which gives hope). However, I don't know HOW this was solved or worked around and haven't got a clue where to start. Please help.

I'm looking to buy a relatively inexpensive laptop to run Linux on. My budget is USD $1000. I'm curious if anyone has recommendations as to what makes a good choice for use with Linux. I plan to use the 2.6 kernel, and am looking for something light with a decent battery life.

Centrino technology sounds nice, with its small size and such. Linux support is more or less there, however it sounds like Intel's not sharing the needed specs with the free and open source communities.

HI,
does anybody know if there is a possibility to use the cool n quiet mode of the AMD 64 CPU's on Linux?

LocalAreaSecurity.com has released a new version of their live-CD Linux distribution for information security professionals. It contains over 200 security tools including all the usual suspects (Nmap, Nessus, etc.) as well as many other great tools less well known. The ISO images are meant to be burned on 185MB and 210MB miniCDs which they update around twice a month. L.A.S. also publishes many papers on how to use the tools as well as research docs on *nix security. Their latest papers include:

I have modified a USB device driver into a character devcie driver, so that it doesn't use the usb interface any longer , as in, usb_register(), usb_findinterface, usb_probe et al.,aren't used ...
The driver now just has ioctl calls for device specific functions which it does with some structs defined already for the device file.
Here's the problem:
Though I am not using the usb device driver, I need to register the char dev driver for usb devices, so when I use a major number of 180 and a minor no of 192, i get the following error:

Hello...

I have some jobs that I wish to run in the background. I don't really care how long they take to run, so I don't want my general system performance to be affected (well, not too much, at any rate :-)

I've tried nice'ing the processes, but that doesn't quite achieve what I had in mind.

Here are two example situations for you to ponder:
* converting a directory of .WAV files into .OGGs (a purely CPU intensive task)

ok, I'm running a stock RedHat 9 system. I found multiple documents on how to upgrade it to 2.6 I followed them very closely. I am having a Kernel Panic when it tries to boot. I have (2) 1.2 gig drives mirrored as the boot partition /dev/md0. I have the swap partition ad /dev/md1 I then have a large data partition on 2 other drives as /dev/md2. Kernel sees the md drives and creates the raids. I can see on the screen that it created md0. it also says that Personality 3 is not loaded. then it stops the raid? then it unbinds to the raid. then it says autorun done.

Hi guys,

One time I compiled and install the a new kernel 2.6.5 image, I received this message on boot:

...
loading kernel/fs/reiserfs/reiserfs.o
No module found in object
insmod: error inserting '/lib/modules/2.4.21-199-default/kernel/fs/reiserfs/reiserfs.0': invalid module format
kernel panic: VFS: unable to mount root fs on hda7

I know that there is a module problem. I don't know why try to use a module from the previous kernel. In the /usr/src the folder linux is a simbolic link to the new kernel. It seems like they use references to the previous modules, but I don't know when he looks for this modules and how I can solve it.

I'm very interest in it.maybe redhat advance server 3?debian unstable? gentoo?suse?

more and details appreciate

I'm writing a simple USB driver for the "Delcom USB Numeric Display"
http://www.delcom-eng.com/products_USBNDisplay.asp Why would I create
additional files for user-space "input" under the sysfs tree? Instead,
wouldn't it be better to create files off of proc (virtual file system in
ram) verses the disk based sysfs tree? It's the 2.6 kernel which now has
entries under " /sys/bus/usb/drivers.."

Hi guys,

I have some little doubts concerning the 2.6.X compilation...

I know the first orders:
1- make xconfig
2- make bzImage && make modules && make modules_install
3- cp arch/i386/boot/bzImage /boot/vmlinuz-2.6.4
4 cp System.map /boot/System.map-2.6.4

But from there, there is some different versions..
I have to copy System map to the /boot folder. how Linux recognise the relation with each kenel image and his System.map? with the surname?
