Hack web-enables Linux config/build process

Kirk Murrin of Linux Guru Consulting has published a clever looking demo hack that adds a web interface to mconfig. The hack aims to let users configure and build Linux kernels remotely, access kernel and driver documentation, and even use browser forms to add and edit source files.

Compression & Decompression at Kernel Level

I want to modify the linux kernel 2.4 to treat the compressed files as the directory & allow all the directory operations to be performed on them.
This modification will obsolate all the Compression & Decompression tools avilable today,like GUNzip etc.

I want to do this as my semester project.
I have around 3 months with me.
Please tell me about its feasibility.

Can't Comment on "Linux: Documenting Memory Barriers"

I can't seem to add a comment to the story on the main page about the documentation to the Linux memory barrier API. There is simply no "add new comment button" like there is on all the other main page postings.

Could this be because it was posted by Amit instead of Jermey?

Thannks!

Process exit notification to kernel module

Submitted by hnagalla
on February 14, 2006 - 5:27pm
KernelTrap

Is there a mechanism for a kernel module to register for a specified process exit notification. In our example the kernel module allocates certain resources for the process and in the event of abnormal termination of the process, we would like to clear the resources allocated by the kernel module.. Any suggestions on how process exit notification can be propagated to the kernel module?

Trying to find out EXACTLY what a system call is doing with respect to kernel mode...

Hello everyone!

I have a particularly vexing problem. For part of my research, I would like to know what 'kernel-mode calls' a particular system call is making. I am aware that strace allows us to see what low level system calls are made at the kernel-mode, user-mode interface. The problem with strace is that it stops at the lowest possible level of user mode. For my purposes, I need to know what those particular low-level user mode system calls are actually doing with regard to the kernel.

Asynchronous signals to user space

Submitted by kb88

Hello,

Is it possible for Kernel to "write" to userspace asynchronously to a program which does not "sleep" on read()?

The userspace opens my device, registrants itself and provides the address where the mydev will write a value when something changes.

ioctl (MYEVENT_ID, &value);

I do not want to keep the userspace in sleep on device, it is not essential to notify it when exactly the value is being changed, I just like mydev to "write" to userspace asynchronously like to shared memory.
