File descriptor handling changes in 2.6.27File descriptor handling changes in 2.6.27
[Kernel] Posted Aug 4, 2008 15:31 UTC (Mon) by corbet
One of the changes merged for 2.6.27 is a set of system call extensions designed to get around some longstanding security issues with POSIX file descriptors; LWN covered these extensions back in May. Now the author of that work (Ulrich Drepper) has posted a description of these changes, why they are important, and how they will be used in the C library. Worth a look, especially for developers working on threaded applications.
