Description

This patch adds support for the for BSD-style xattrs interface (which is almost identical to Linux's attr/xattr.h, except in regard of symlink traversing options)

It allows building Haiku on Mac OS X with --use-xattr from a ZFS volume (HFS+ does not work though).

How does the symlink behavior differ? Are symlinks always or never followed by the functions? In the former case the semantics of the mapped attribute API would differ.

Replying to bonefish:

Like in Linux you can choose to follow symlinks or not, but instead of choosing between two functions (getxattr/lgetxattr), you add the flag XATTR_NOFOLLOW to the options.
