Various functions would return an error if trying to use them on the last page of userspace, as they tested the permissions for the first byte out of the requested range. Also, the code was duplicated in several places - Rename validate_user_range to validate_memory_range. The "user" in the name was to mean that the range is provided by the user calling the syscall, but it is a bit confusing, as the function accepts any range that is either in kernel or in user memory. - Add a new function validate_user_memory_range that only accepts userspace memory, and use this one where appropriate.

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.
