This change refactors the Unix socket / pipe backend to have a ring buffer containing segments, where each segment has an optional leading ancillary buffer containing control messages followed by a normal data buffer. The SCM_RIGHTS control message has been implemented which transfers file descriptors to the receiving process. File descriptors are reference counted and cycles are prevented using the following restrictions: 1) Unix sockets cannot be sent on themselves (on either end). 2) Unix sockets themselves being sent cannot be sent on. 3) Unix sockets cannot send a Unix socket being sent on. This is a compatible ABI change. |

The Sortix Operating System =========================== Sortix is a small self-hosting operating-system aiming to be a clean and modern POSIX implementation. It is a hobbyist operating system written from scratch with its own base system, including kernel and standard library, as well as ports of third party software. It has a straightforward installer and can be developed under itself. Releases come with the source code in /src, ready for tinkering. It has been in development since 2011 by a single developer and contributors. Though the system is stable and capable right now, it is still early in development, and a number of crucial features haven't been made yet. Releases are made yearly and future releases will add features such as networking, SMP, and USB that were skipped in favor of becoming self-hosting now. Documentation ------------- The system is documented as manual pages. Introductory system usage is covered in the user-guide(7) manual page. Links ----- For more information, please visit the official website: https://sortix.org/ Building Sortix --------------- Development of Sortix under itself is covered in development(7). Development from another operating system is covered in cross-development(7). You can view the cross-development(7) manual page with this command: man share/man/man7/cross-development.7 License ------- Copyright 2011-2016 Jonas 'Sortie' Termansen and contributors.
