Augustin Cavalier d9694912a7 kernel: Have wait_for_thread fail with EDEADLK when the current thread is specified.
This behavior is not required by POSIX (for pthread_join), but it
is recommended and other OSes seem to implement it.

This constitutes a behavioral change from BeOS, which just deadlocked
as we do before this commit (I checked.) Preserving this behavior does
not seem very useful, though if in the future we need to, adding a check
to libroot is easy enough.

This fixes a deadlock encountered when the usb_rndis driver is unplugged;
the network stack has a removal path that invokes wait_for_thread on
the receive thread, but the function can itself be called from the
receive thread.

Haiku

Homepage | Mailing Lists | IRC Channels | Issue Tracker | API docs

Haiku is an open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.

Goals

  • Sensible defaults with minimal configuration required.
  • Clean, clear, concise code.
  • Unified desktop environment.

Trying Haiku

Haiku provides pre-built nightly images and release images. Haiku is compatible with a large variety of hardware, but in case you don't want to "take the plunge" and install Haiku on bare metal, you can install it on a virtual machine (VM) instead. If you've never used a VM before, you can follow one of the "Emulating Haiku" guides.

Compiling Haiku

See ReadMe.Compiling.

Contributing

Haiku is a meritocratic open source project with a large variety of tasks. Even if you can't write code, you can still help! Haiku needs designers, (technical) writers, translators, testers... Get involved and help out!
