Linux, politics, and other interesting things
In regard to my post yesterday about Planet Debian I received the following response:
James Purser said I’m betting that your feed is an atom feed. We had the same problem on PLOA with Jeff and Pias feeds when they switched to atom. Planet needs to be upgraded.
Well I am using an atom feed, so this probably explains it. Sorry for the inconvenience to the Planet Debian readers, I guess that things will stay the way they are until it is upgraded.
Also when viewing my blog entry in Planet Debian I realised that much of a spam message had got pasted in to the URL field for the Planet Debian link. Oh the irony that I only found this embarassing error because of a bug in the Planet software.
This brings me to another issue, Security Enhanced X. With SE-X (before you ask, I didn’t invent the acronym) you can use SE Linux to control communication between windows on an X desktop. With a modification to the clipboard manager (klipper in the case of KDE) every piece of data that’s copied from an application will have a security context assigned to it and this context will be checked against the context of an application that is to be the target of a paste operation. Klipper will also have to support relabeling clipboard data. Therefore if I want to cut text from my email client (Kmail) and paste it into Firefox then I would have to relabel it with the appropriate MCS categories. This would permit me to paste text from an email into a web form with a few extra mouse clicks, but would prevent me from accidentally pasting the wrong text. Keeping in mind the fact that there are many more embarassing things that could be accidentally pasted into a blog entry than the contents of a spam this doesn’t seem overly difficult.
PS Before anyone jumps to conclusions. When I receive GPG encrypted email or other material that should be kept confidential I try and avoid cutting it, and if I have to do so I clear the clipboard buffer afterwards. Keeping spam a secret is not really a priority to me so I didn’t take adequate precautions in this case.
