I have just added ÂImplement Missing Interfaces for GNU HurdÂ,
<https://sourceware.org/glibc/wiki/GSoC#Implement_Missing_Interfaces_for_GNU_Hurd>:

| == Implement Missing Interfaces for GNU Hurd ==
| 
| In glibc's Linux kernel port, most simple POSIX interfaces are in fact just forwarded to (implemented by) Linux kernel system calls.
| In contrast, in the [[http://www.gnu.org/software/hurd/glibc.html|GNU Hurd port]], the POSIX (and other) interfaces are actually implemented in glibc on top of the [[http://www.gnu.org/software/hurd/hurd/rpc.html|Hurd RPC protocols]].
| A few examples:
| [[https://sourceware.org/git/?p=glibc.git;a=blob;f=sysdeps/mach/hurd/getuid.c|getuid]],
| [[https://sourceware.org/git/?p=glibc.git;a=blob;f=sysdeps/mach/hurd/open.c|open]],
| [[https://sourceware.org/git/?p=glibc.git;a=blob;f=sysdeps/mach/hurd/rmdir.c|rmdir]],
| [[https://sourceware.org/git/?p=glibc.git;a=blob;f=sysdeps/mach/hurd/setresuid.c|setresuid]],
| [[https://sourceware.org/git/?p=glibc.git;a=blob;f=sysdeps/mach/hurd/socketpair.c|socketpair]].
| 
| When new interfaces are added to glibc (new editions of POSIX and similar standards, support for new editions of C/C++ standards, new GNU-specific extensions), generally [[https://sourceware.org/git/?p=glibc.git;a=blob;f=posix/execve.c|ENOSYS stubs]] are added, which are then used as long as there is no real implementation, and often these real implementations are only done for the Linux kernel port, but not GNU Hurd.
| (This is because most of the contributors are primarily interested in using glibc on Linux-based systems.)
| Also, there is quite a backlog of [[http://darnassus.sceen.net/~hurd-web/open_issues/glibc/#missing|missing implementations]] for GNU Hurd.
| 
| In coordination with the [[mailto:bug-hurd@gnu.org|GNU Hurd developers]], you'd work on implementing such missing interfaces.

Please review/edit/amend/polish this (please shout if you need to be
added to <https://sourceware.org/glibc/wiki/EditorGroup>), and then I'll
soon ask Josà to also include it on
<http://www.gnu.org/software/soc-projects/ideas-2014.html> as well as put
it on/link to it from
<http://www.gnu.org/software/hurd/community/gsoc/project_ideas.html>.


GrÃÃe,
 Thomas
