Hello, when i compiled latest linux 2.6.4 kernel source with gcc 3.3.2 on Linux/x86, i got a few warnings about varaibles beeing compared against constants where the range of the variable is so that the expression is always constant. The explicit comparison has to do with the code for high-uid and gid sheme. attached you will find a diff which does eliminate this error message by introducing an

Hi, ? I'm using the procedure described in building customer kenrels centOS5.0. ? Except for one step where spec file to comment 25 lines from 638, I did every thing. I got rpm files in ~/rpmbuild/RPMS. After installing kernel-firmeware, kernel, kernel-headers, kernel-devel packages it creates OS entry in /boot/grub/menu.lst?following "defaults 0" directi...

Hi! Attached patch makes xen-tools and stubdom-dm going independent from hardcoded pathes. It is no possible to install into /usr/local or any other non-default directory and use it out-of-the box. This allows us to have different Xen versions in different directories, simplifies packaging for distributions. It also finds ''hvmloader'' and

Hi, Even though I am not running a centos.plus kernel yum wants to install the kernel-debuginfo for it. # yum install --disablerepo=\* --enablerepo=base-debuginfo kernel-debuginfo Loaded plugins: fastestmirror, refresh-packagekit Setting up Install Process Loading mirror speeds from cached hostfile Resolving Dependencies --> Running transaction check ---> Package kernel-debuginfo.x86_64

The original commit adding that check tried to protect the kenrel against a potential invalid NULL pointer access. However we call nouveau_connector_detect_depth once without a native_mode set on purpose for non LVDS connectors and this broke DP support in a few cases.

If we do rsync with an nfsv4-style transport, then ACLs will be transported as attributes of a file, abstracted into a POSIX/NT common format. For them to be transported successfully, both machines would have to support ACLs either in the kenrel or through some kind of vfs that stores them in a database. Also, ACLs are defined in terms of usernames so they'll have to have a common username database or a way of mapping from one to the other. Since ACLs are transferred into the native filesystem scheme on the destination, data that c...

Hello: I am using kvm on a CentOS 5.4 server. I am trying to install the TunkeyLinux Core appliance found here: http://www.turnkeylinux.org/core I downloaded the ISO file from the web site. Then, I used this command to intall it: virt-install -n tkl-core -r 512 --vcpus=1 --check-cpu --os-type=linux --os-variant=ubuntuhardy -v --accelerate -c /tmp/turnkey-core-2009.10-hardy-x86.iso -f

...ely bogus, since allowing > normal kernel code to issue random syscalls had never been an intention. Well, AFAICT kernels have pretty much always done direct syscalls in some places.
