Move existing project definitions from projects/gsoc_2011/ to
The goal for this reorganization is to remove any knowledge of the projects
classification from the file hierarchy: the classification goes into tags,
and projects indexes automatically list projects based on such tags.
Also, the current gsoc_2011 name was wrong anyway, because GSoC 2011 has
already concluded and projects would have had to move to a gsoc_2012 directory
Lastly, yes, "projects/project/*" is slightly redundant. But I want to keep
the project lists from the projects "database" clearly separated.
This is as proposed in www@.
title="Secure-PLT - supporting new PLT formats on alpha"
Currently kernels with options PAX_MPROTECT can not execute dynamically linked binaries on most RISC architectures, because the PLT format defined by the ABI of these architectures uses self-modifying code.
New binutils versions have introduced a different PLT format (enabled with --secureplt) for alpha and powerpc.
This project (for alpha) is to add support for the new PLT formats introduced in binutils 2.17 and gcc4.1 This will require changes to the dynamic loader (ld.elf_so), various assembly headers, and library files.
Support for both the old and new formats in the same invocation will be required.
For all architectures we can improve security by implementing [relro](http://tk-blog.blogspot.com/2009/02/relro-not-so-well-known-memory.html).
