Debian :: Security Update 'broke' Kernel / Recompile It?
May 25, 2011
I installed the latest security update for squeeze. It entailed an update of the kernel. Now when it boots, it give continuous kernel error messages about "can't enumerate usb .... " I have a custom kernel compiled from source (not sure about the patch level) from the same kernel 2.6.32. It seems to work OK. Should I worry about the security of this custom kernel or should I try to recompile it? I don't really know how to do any patching of the kernel source.

Firstly my gdesklets have gone, and if I try to run gdesklets then I get a blank window in the top left corner, followed by another blank window in the centre which disappears, then the first one fades to gray.
Secondly, clicking the 'running man' to exit just closes both gnome panels.
Ubuntu 8.04 (2.6.24-25)I know 8.04 is pretty old now, and I should probably start over, but it was all fine until this latest update.

Posting from my Windows 7 system. Once again an Ubuntu kernel update has broken X. Once again I cannot get into Grub2, despite putting in the hacks to lengthen the time it listens. I don't need instructions on how to fix it from Live CD. I'm going to try Gentoo or something, anything, different. I need a Linux distro that can survive regular updates and boot to desktop reliably.

I am running Ubuntu 10.04 and ran the normal weekly updates last night. There were kernal updates listed but they have run alright before so I went ahead and let everything update.
On restart my Nvidia drivers would not load, so I restarted in low graphics mode. I uninstalled the Nvidia driver (with the intent of reinstalling them) but decided to restart before I reinstalled the driver (windows habit). upon restart I was told (in a very small box) that Ubuntu was running in low graphics mode.
I clicked ok and it proceeded to load, but it loaded it in regular mode and only the right half of the desktop is visible! It is like it is cut totally in half! And I can't get to the important side with Admin and Preferences. I tried boot options but that just gets me a very small colored box. There are no options when it boots just 3/4 of a box that says it is running in low graphics mode because "unable to load module "fglrx" module does not exist". I can not try and reinstall the Nvidia drivers because I can't see the part of the desktop that has Admin on it. I have used Ubuntu for several years now but have not used the terminal very often.

My GMA500 (poulsbo) driver is not working any more because of the latest update I made using Software Update.
The update was a new kernel:
[omass@omass ~]$ uname -a
Linux omass 2.6.30.10-105.fc11.i586 #1 SMP Thu Dec 24 16:26:26 UTC 2009 i686 i686 i386 GNU/Linux
Now, after this update, when I reboot I get the following error code...

From the securing-debian-howto [URL] ...
"4.2.2 Security update of the kernel
First, make sure your kernel is being managed through the packaging system."
which suggests...
Code: Select all$ dpkg -S ‘readlink -f /vmlinuz‘
When I try to confirm by running the above, I get a lot of characters of output but the last line reads...
Code: Select alldpkg-query: no path found matching pattern /vmlinuz‘
How do I make sure my kernel is being managed through a packaging system?

Latest kernel update on 10.04 desktop broke my bluetooth. The icon in the tray has now faded and pushing 'turn bluetooth on' does absolutely nothing. I'm on a Lenovo S10-2 laptop, everything was working perfectly before today's update.

I just updated my kernel from 2.6.32-21 to 2.6.32-22 today. Now I am getting no sound. I have checked my mixer levels with both kmix and alsamixer. Nothing appears to be amiss. I tried rebooting with the old kernel and still no sound.

I managed to get my Linksys AE1000 USB wireless adapter to work on Unbuntu 10.04 LTS.but recently I updated the kernel to 2.6.32-26 and when i rebooted I logged on to see my wireless connection was not working.even worse, I can't fn the links i had that showed me how to install it in the first place, its about the fact that the new kernel uses a different usb setup(probably incorrect, let me know it its incorrect). its an issue that the hacked driver isnt compatible with the new kernel release, how can i revert to the older version that it did work on? i'm using a RALinkTech driver [URL]

I have recompiled a few kernels, but all on 32bit systems so not sure if that has anything to do with it.
Running Arch Linux 64bit, most recent version.
Kernel Output:
Code:
My first thoughts was that it might be my grub bootloader configuration, so had a big play around with that but it didn't fix it. Also made sure support was built for filesystems. However almost all that Fstab mounts are ext3 anyway, and certainly the root and /boot are. Now thinking it may be a memory error so will run a check when I shutdown.

Yesterday, I ran a security update that upgraded my Squeeze kernel from 2.6.32-48squeeze8 to 2.6.32-48squeeze9.
Ever since then, my suspend to ram (STR) function is broken.
The machine will suspend normally, but will not resume. When I try to awaken the machine, I can hear the fan in the tower start up (the subject machine is a desktop computer, please see below for specifics), but the machine seems to be otherwise dead (e.g. the monitor stays blank, pressing the "caps lock" key on my keyboard does not activate said keyboard's "caps lock" led, Ctrl-Alt-F[x] has no effect, etc). My only recourse at that point is a hardware reset (ouch!).
I tried running Code: Select allpm-suspend from a terminal, with no joy. Same result running Code: Select allecho -n "mem" > /sys/power/state from a terminal.
I checked the /var/log/pm-suspend.log file and noticed that each Code: Select all...performing suspend line used to (before said kernel upgrade) be directly followed by a Code: Select all...Awake. line, but, now, all said Code: Select all...performing suspend lines are followed by an Code: Select allInitial commandline parameters... line.
Before this, STR has worked well ever since I first loaded Squeeze on this machine back in 2012.
Code: Select allSqueeze 6.0.10; 2.6.32-5-amd64
Intel i7-980 Gulftown CPU
Asus P6X58D Premium Motherboard
EVGA GeForce GTS-450 Graphics Card

I just performed the newest kernel update to version 2.6.37.6-0.7 (desktop). Unfortunately, there is no update for the compat-wireless package available. It's still the version for kernel 2.6.37.6-0.5. Hence, my wireless is currently not working and I had to pull a cable through my apartment to write these lines. I actually thought due to the change of the very last digit in the kernel version that this should be a rather safe update. But I also had to recompile the modules of the NVidia driver and of Virtualbox. Does anyone has an idea when new compat-wireless modules will be available? Or do I have to re-compile them myself (I never had to do that before and I really hope that I don't have to)? Or is there a trick to make the old modules work?

I have a asus M51 Se that not work with 4GB of memory ram, due to a bug of bios. Only work with one slot of 2GB. I find this link https://bugs.launchpad.net/ubuntu/+s...ux/+bug/316079 that help to solve my problem. But for that I have to change a file.
My question is I need to recompile the kernel that I have? if yes, how can i make that without installing other kernel.

I tried to run some virtual machine using Virtual Machine Manager but the guest OS (windows server 2003) was not able to "see" the rest of my network. I believe VMM did some NAT-ing (192.168.122.x subnet) so i'm not able to "see" my network. I tried various network setting in VMM but couldnt get it to pull my network IP (192.168.1.x subnet).So i installed VirtualBox as a work around because i know VB work when i tried it on my windows machine. I ran into some issue getting VB to run, i think it was that i need to compile the kernel to "optimize" it for VB. I am fairly new to linux so that the impression that i get when i research for the fix to get VB working. In some of the forum post people suggest few things and it seem to me like it to compile the kernel. After a few hours of working i finally got it to compile but the computer crashed during compilation.
I am guess what happened is that i was trying to optimize the kernel for VB but the version of kernel i was using (2.6.18-164.6.1.el5xen) is already optimized for xen (VMM) so it crashed. I am looking to restore or recompile the 2.6.18-164.6.1.el5xen kernel. I am not sure if this is the right thing to do to fix it. With my limited knowledge of linux that all i can think of.

I am working with OpenCL (note that is different from OpenGL) and recently upgraded from nvidia driver 190.29 to 195.36.15 . After a bit of experimentation i decided to downgrade back to 190.29
However after i did this X complains that i have nvidia kernel module 190.42 and it does not match with nvidia drive 190.29 . Could some one tell me how to recompile the kernel module for 190.29??

I wish to recompile serial_core module to make a change in the way ioctl works. I don't wish to rebuild the whole kernel package. Can someone point me to the proper method?? I know I will need to download the kernel headers etc. But I would like to avoid the unneeded compiles of things I don't need to recompile.

I need to recompile a kernel and I am wondering why I have a /usr/srckernels directory instead of a /usr/src/linux directory?
I installed all the packages I thought I needed.... kernek-devel, gcc, make...
What am I missing to do this "correctly"?

This has got me stumped. I expected to do /etc/init.d/vboxdrv setup after the upgrade from 11.3 to 11.4 but the command fails. The log is (it seems to repeat so I only quote the final bits to make it fit into the wordcount limit):
Code:
make KBUILD_VERBOSE=1 -C /lib/modules/2.6.37.1-1.2-desktop/build SUBDIRS=/tmp/vbox.0 SRCROOT=/tmp/vbox.0 modules

I've been playing around in attempt to see how small a usable kernel I can build. The theory is that it should mainly be useful for preparing a recovery disk or some such thing; disk drivers and a few network drivers are what goes in.
I built the kernel with the attached config. It boots, reaches the hdd (if I specify root as /dev/sda5 manually), then dies when it tries to start Plymouth (something about catching a SEGV signal). What needs to be enabled to run Plymouth? Alternatively, has anyone managed to remove plymouth from boot on Maverick?
(That would require a modified mountall version, I know.) I'm using the mainstream kernel 2.6.32.27 sources on Maverick (yes, I know Maverick uses 2.6.35; but this does boot).
Hardware: Wireless-RTL8192SE b/g/n, uses an out-of-tree driver (r8192se_pci, from Realtek; Ubuntu builds in an older version of this driver); r8169 works for ethernet; ATI Radeon Mobility 3200 graphics, AMD Neo X2 cpu; SATA hd in AHCI mode.

The update that broke things contained some 400 packages.The problem is NOT hardware related. There are 2 other linux installs on the laptop that work the way they should.This is all related to using a wired network connection.The update removed the package network-config and did not replace it. Not sure that is the problem because that package is related to the gui and I can not get an ip in cli.
I am stuck at cli because the new kernel broke nvidia (pretty normal). There was also a new xserver, which tends to break nvidia, and as I recall a new kde. Anyway I am unable to rebuild the nvidia driver because I can not establish a network connection to my network to get the packages needed to fix it.

I have a very strange problem; when trying to apt-get update or aptitude update I get time out errors. At first it was resolving ipv6 adresses:
Cannot initiate the connection to ftp.litnet.lt:80 (2001:778::87). - connect (101: Network is unreachable) [IP: 2001:778::87 80] Err [URL] Cannot initiate the connection to security.debian.org:80 (2001:a78:5:1:216:35ff:fe7f:6ceb). - connect (101: Network is
unreachable) [IP: 2001:a78:5:1:216:35ff:fe7f:6ceb 80] As my host does not have normal ipv6 support, i just tried to disable ipv6: echo net.ipv6.conf.all.disable_ipv6=1 > /etc/sysctl.d/disableipv6.conf

I would like to recompile the openssh-server with a different version string. I download and compile the source, but so far I have only been able to compile and run the client. Not the server.
Steps taken:
Is there a flag or option I need to specify to insure that it creates the sshd?

I'm running Ultimate Edition 2.4 on an Acer Aspire 3500 lappy, yesterday I allowed my system to upgrade the kernel (from 9.10 kernel 2.6.31-17 to 2.6.31-18 generic) as per usual but when it rebooted I had no WiFi. The network manager didn't even have a wireless section, only wired, and I couldn't setup a wireless network either. If I reboot into the earlier 2.6.31-17 kernel everything is OK.
Another problem is that even tho I have no screensaver enabled and no power saving options enabled, (ie screen never disabled) after a short time of no use the screen goes blank. If within a few minutes I touch the pad or hit a key the screen returns but if it's been an hour or so nothing I do will wake it up,even tho there is still disk activity etc, and the only way to recover is with a hard reset, hold power key to reboot.

I am having an issue with phpMyAdmin on my Xubuntu machine. I installed a few updates today and now my phpMyAdmin web interface site is not loading on the server. This is a local server running in my office. It appears that the page tries to load, but no output is delivered to the screen.
Taking a closer look at my updates, it looks like the following changes were made (along with some upgrades to Firefox):
When I use the 'Force Version....' command, I am given only two options the '4.8' version that I have now (the broken one) and a flat '4' version with no .7. Also, the force version didn't seem to do anything. I tried to Force a version and then mark a package for reinstall. When I did this Synaptic informed me that it was simply going to reinstall the 4.8 version.
What I would like to do is to revert to the 5.3.2-1ubuntu4.7 version of all of these files and then lock the version using Synaptic, to prevent this issue from recurring.
I am not afraid of heading to the command line either.
System Information:
32-Bit Xubuntu 10.04 LTS install
Athlon 3800+
