What steps will reproduce the bug?
Input:
const net = require('net')
let server = net.createServer()
server.listen('/tmp/nonexistent/ipc.sock')Output (when run as script):
events.js:304
throw er; // Unhandled 'error' event
^
Error: listen EACCES: permission denied /tmp/nonexistent/ipc.sock

Emitted 'error' event on Server instance at:

at processTicksAndRejections (internal/process/task_queues.js:80:21) {
code: 'EACCES',
errno: -13,
syscall: 'listen',
address: '/tmp/nonexistent/ipc.sock',
port: -1
}
When run directly in the node prompt, the output is different, but the difference is not relevant here.
How often does it reproduce? Is there a required condition?
Always reproducible, no conditions
What is the expected behavior?
The error message tells something like "ENOENT: no such file or directory", code and errno show 'ENOENT' and 2 (or maybe -2) respectively.
What do you see instead?
The error message claims that there was a permission denied error (EACCES), which is not the case.
Additional information
Relevant excerpt from strace:
socket(AF_UNIX, SOCK_STREAM|SOCK_CLOEXEC|SOCK_NONBLOCK, 0) = 18
bind(18, {sa_family=AF_UNIX, sun_path="/tmp/nonexistent/ipc.sock"}, 110) = -1 ENOENT (No such file or directory)
close(18)
This clearly shows that the OS actually does report ENOENT correctly, but somehow that gets mangled into EACCES.
