GCM Cipher Specs

The GCM cipher mode is now included in the mainline kernel. It is, at least in theory, a very viable alternative to less secure modes as far as speed is concerned, but also offers some degree of authentication.

Just one problem- I can't figure out how to get the thing working under LUKS with cryptsetup.

I've tried various permutations of:

(cipher)-gcm-essiv:(hash)

Hi, I am running a network server and a very large sql database and have noticed some wierd stats in top. I am new to the top output so this may be really simple... I see in some instances where the total %cpu time goes over 100 between updates. Is this normal, more so how do I interpret this?

Hi,

what's the common practice for describing the authors and the copyright of kernel code released under the GPL2?

Let's make an example:

the developer A releases a code.c for the linux kernel and specifies himself and other contributors as Authors.

Some time later the developer B

- refactors the same piece of code (due to massive core changes)
- adds new functionalities

Hello all,

Apologies in advance if it's a stupid question, but I can't find its solution anywhere else. I am trying to shape network traffic on an interface (100Mbps) which should only permit 1.5Mbps bandwidth and has sfq filter attached to it. I have used the following tc qdiscs.

Question about swap

I have a question about swap. Will swap be used if the process is active and using all of the physical ram?

It was my understanding that swap will _not_ be used if the process is active. We have an application that uses all of the physical ram then gets an OOM error and crashes but we have 4 gb of swap and i just wanted to be sure i am understanding it right or not understanding it right.

I am using a bus adapter to allow access from a VME system to a user shared memory segment. The driver for the adapter can not handle physical addresses above 4GB. Unfortunately, I have 16GB in my system. I would like to force the physical memory addresses returned by shmget() to be below the 4GB boundary.

Having an issue with CentOS 5.1 - after install there is a process called nash-hotplug that is running and consuming 100% of one of my CPU cores (QuadCore Xeon CPU). Seems to be a 'nice' process as it steps out of my way when other apps need all the CPU, but I am struggling to understand what it is.
