As far as I can tell only opendir should be using the O_DIRECTORY flag in open.
From the man page: "If pathname is not a directory, cause the open to
fail. This flag is Linux-specific,
and was added in kernel version 2.1.126, to avoid denial-of-service
problems if opendir(3) is called on
a FIFO or tape device, but should not be used outside of the
implementation of opendir."
Does this race exist in BSD opendir?
If ant is using this, is it through opendir?
Only reason I can see to introduce this in the base is if this problem
also exists on dragonflybsd.
