Tracking issue for libredox migration

redox_syscall is used in lots of places in userspace, and should, except for low-level userspace components, be replaced by libredox.

Such crates can be found both by searching for reverse-dependencies on crates.io, and directly checking redox repositories.

Libredox isn't 100% feature-complete yet, but this can be done incrementally.

Recipes using redox_syscall directly

• zerod - zerod!5 (merged)
• userutils - userutils!43 (merged)
• redoxfs - redoxfs!71 (merged) (except unstable mremap)
• ramfs - ramfs!5 (merged)
• ptyd - ptyd!8 (merged)
• randd - randd!12 (merged)
• orbterm - orbterm!21 (merged)
• orbital - orbital!54 (merged) orbital!55 (merged)
• orbutils - orbutils!62 (merged)
• nulld - zerod!5 (merged)
• netutils - netutils!46 (merged)
• netstack - netstack!46 (merged)
• logd - logd!4 (merged)
• ipcd - ipcd!6 (merged)
• init - init!10 (merged)
• installer - just needs pkgar update, but broken anyway: installer#18
• extrautils - extrautils!55 (merged)
• coreutils - coreutils!209 (merged)
• audiod - audiod!2 (merged)

Exceptions

• relibc - currently the very library providing the libredox symbols
• bootstrap - relibc isn't available when bootstrap runs
• escalated - uses relibc internals directly
• kernel - obviously allowed to use redox_syscall
• bootloader - only uses definitions and for error handling
• drivers - drivers!150 (merged), drivers!151 (merged) (except virttophys and iopl)
• contain - not really used yet

Notable crates depending on redox_syscall

• redox_users
• redox_termios
• redox_event
• termion
  • redox_liner
• tempfile - only uses error::ENOSYS
• filetime - https://github.com/alexcrichton/filetime/pull/103 (not yet released, but Redox's fork works for now)
• parking_lot_core - currently shortcuts to common unix code, but should be changed to add futex, see #3
• winit - backported so calculator can use it, TODO needs upstream
• softbuffer - backported so calculator can use it, TODO needs upstream
• orbclient
• datetime - used by eza, but looks unmaintained
• tokio-tar
• redoxfs
• redoxer
• redox-daemon
• ...
