Exploiting Recursion in the Linux Kernel

Filed under
Linux

On Linux, userland processes typically have a stack that is around 8 MB long. If a program overflows the stack, e.g. using infinite recursion, this is normally caught by a guard page below the stack.

Linux kernel stacks, which are e.g. used when handling system calls, are very different. They are relatively short: 4096 bytes on 32-bit x86, 16384 bytes on x86-64. (The kernel stack size is specified by THREAD_SIZE_ORDER and THREAD_SIZE.) They are allocated using the kernel's buddy allocator, which is the kernel's normal allocator for page-sized allocations (and power-of-two numbers of pages) and doesn't create guard pages. This means that if kernel stacks overflow, they overlap with normal data. For this reason, kernel code must be (and usually is) very careful to not make big allocations on the stack and has to prevent excessive recursion.

Fedora 24: Comparing Gnome, KDE Plasma, Cinnamon, MATE, Xfce, LXDE

Filed under
Linux
Red Hat

It is interesting to look at the gaps in this table - for example, the KDE spin doesn't include digiKam, which seems very odd, and please don't try to tell me that Gwenview should count as a photo management application! Why does the Cinnamon spin not have a music player? Perhaps I overlooked it... but I don't think so. Also, even though LXDE is expected to be a lightweight distribution, the lack of any kind of PDF viewer seems rather extreme.

So that's the whole family -- six different desktops, ranging from the most fully equipped to the most leanly stripped. They will all be available starting Tuesday, 21 July from the Fedora Downloads page. Get it while it's hot!

  • Canonical, Snappy and the marketing value of collaboration
    Canonical implies it is collaborating with nearly every major Linux distro for its Snappy project. It is not. And what could have been a marketing win for it is now a loss.
  • How to install MongoDB community edition on Ubuntu Linux
    MongoDB is a NoSQL database that avoids the traditional structure of relational databases in favor of document-oriented JSON-like objects. What this translates to is the integration between application and data is faster and easier. If that's not enough, consider this: MongoDB is one the databases preferred by big data and large enterprise companies, including Adobe, Craigslist, eBay, FIFA, Foursquare, and LinkedIn.
  • No WhatsApp, but fixes set to come for Ubuntu Phone

  • Ubuntu Developers Discuss Again About Dropping Support For 32-bit x86
    Ubuntu developers are once again pondering the possibility of dropping support for i386 (32-bit x86) as installation media for their Linux distribution. The matter of dropping Ubuntu i386 ISOs has been brought up many times the past few years, but ultimately it's kept getting pushed back for users still running Ubuntu Linux on old hardware and other reasons. Dropping Ubuntu for i386 keeps getting brought up namely for the installer media rather than the i386 package archive itself.

Android Apps Turn Chromebooks Into Macbook Killers

  • Android Apps Turn Chromebooks Into Macbook Killers
    When Chromebooks launched in the summer of 2011, they seemed destined to fail, much like the underpowered, internet-dependent netbooks that came before them. But in the five years since, Chromebooks have defied expectations, becoming the most used device in US classrooms and even outselling Macs for the first time this year. Still, people complain about their inability to run useful software, but that’s all about to change.
