kernel: excessive in kernel CPU consumption when creating large nested epoll structures

The epoll implementation in the Linux kernel 2.6.37.2 and earlier does not properly traverse a tree of epoll file descriptors, which allows local users to cause a denial of service CPU consumption via a crafted application that makes epollcreate and epollctl system calls...

[SECURITY] Fedora 15 Update: python-tornado-2.2.1-1.fc15

Tornado is an open source version of the scalable, non-blocking web server and tools. The framework is distinct from most mainstream web server frameworks and certainly most Python frameworks because it is non-blocking and reasonably fast. Because it is non-blocking and uses epoll, it can handle...
