Re: stdout to console

Dude, It is more of implementation dependent. Where you want your output to display. pty is a method of sending data between two end points of communications but acts with concept of master and slave. It is written on tty driver. In case of ssh it is implementation dependent. I will leave it to

Netlabel

Hi all, is anyone here familiar with Netlabel ? I am trying to label network packets using CIPSO tags from a LSM module. Rather than using the Netlink interface to configure Netlabel from userspace, I try to setup everything from kernelspace. The way I initialize netlabel is similar to what smack

freelance kernel work

I'm not looking for work, nor do I have any work for others. I'm just curious if there is a central location where freelance kernel developers hang out. I've never seen any email on mailing lists like "I have some hardware and want somebody to write a kernel module for it". I thought that sort of r

Profiling my Modules

Hi All, I have a kernel module which has functions which take a lot of time in execution. I am curious to know how can I profile it, and find out the functions taking most of the time. I saw Oprofile, but it seems that I will have to build the whole kernel, and also that it will be difficult to p
