Augustin Cavalier eeec7ed477 USB: Change from an instant to an unlimited timeout in ControlPipe::SendRequest.
Otherwise we have a race (or worse): in the case where the transfer
has completed or is in the process of completion between CancelQueued
and here, the callback can still be invoked after we returned and
cause corruption.

Discovered while working on USB support in the FreeBSD compatibility
layer: a lock inversion problem meant these timeouts always occurred
but then the callback would be invoked later and corrupt stack.

With this change, such problems will instead cause deadlocks.
That's not an ideal situation to be in, but we should detect
such problems elsewhere and make them into asserts; deadlocks
are assuredly better than random memory corruption.

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!

Contributing code
