Bug ID: 246412
Summary: Return EISDIR when reading a directory
Product: Base System
Version: CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: kern
Assignee: b...@freebsd.org
Reporter: delp...@freebsd.org
FreeBSD have shipped with readdir() and allowing read() on directories is not
very useful.
Other POSIX compliant operating systems like macOS returns EISDIR when
read()ing a directory too, it is allowed in the specification:
Quote https://pubs.opengroup.org/onlinepubs/009695399/functions/read.html :
EISDIR
[XSI] The fildes argument refers to a directory and the implementation does not
allow the directory to be read using read() or pread(). The readdir() function
should be used instead.
