Treat address strings containing slashes as AF_UNIX paths and do not

Do not attempt to calculate a dynamic length for AF_UNIX socket addresses
but return the total size of `struct sockaddr_un`, like we do it for the
structures of other address families as well.
Fixes incorrect domain socket path truncation.

Optimize the poll() function implementation to re-use passed in socket/flag
tuple arrays as-is in the return value array, which simplifies attaching
state to sockets for user code through subsequent fields in the tuple array.

If a non-string value which cannot be interpreted as socket address
structure is passed to connect(), the function will leak the internal
address vector when returning the error.

Actually pass NULL to getaddrinfo() when the service argument is omitted,

Add the required infrastructure to support Linux AF_PACKET sockets:
- Add related constants
- Add struct definitions for SOL_PACKET socket options
- Add AF_PACKET family support to sockaddr routines

When uloop has been integrated with eloop (in hostapd/wpa_supplicant),
uloop_cancelling will return false, since uloop_run is not being called.
This leads to ubus.defer() calling uloop_run in a context where it can
prevent the other event loop from running.
Fix this by detecting event loop integration via uloop_fd_set_cb being set

Introduce a new socket module which provides bindings for the BSD sockets
API to ucode scripts.
Example usage:
import * as socket from 'socket';
let sk = socket.create(socket.AF_INET, socket.SOCK_STREAM);
sk.connect("192.168.1.1", 80);
sk.send("GET / HTTP/1.0\r\n\r\n");
print(sk.recv(4096));
sk.close();

This is needed when asynchronously processing requests via uloop, e.g.
using uclient.
Example script:
let libubus = require("ubus");
let uloop = require("uloop");
uloop.init();
let ubus = libubus.connect();
ubus.publish("test", {
test: {
call: function(req) {
req.defer();
uloop.timer(1000, () => {
req.reply({ msg: "Hello, world!" }, 0);
});
},
args: {}
},
});
uloop.run();
uloop.done();

Use the same RX buffer size which iproute2 uses as default, in order to
avoid (or rather, delay as much as possible) ENOBUFS conditions when
receiving a large burst of netlink notifications.
Signed-off-by: Jo-Philipp Wich <jo@mein.io>

Once we're notified about pending data on the netlink event socket,
try to receive as much messages as possible in order to empty the socket
buffer. In contrast to the previous implementation which received one
message per epoll read notification, this avoids some premature ENOBUFS
situations when a huge burst of messages arrives, e.g. due to kernel
side GC runs on the neighbor table.
Since libnl's nl_recvmsgs*() functions do not expose the underlying
-1 error returned by the recvmsg() calls, we need to indirectly check
for errors through errno variable, so clear it out both before the
recvmsgs() call and after successfully completing a message reception
callback invocation.

Only store the callback reference in the registry once the listener
context was successfully initialized, to avoid keeping a lingering

When the VM instance loading the uloop module has signal dispatching
enabled, implicitly register the signal pipe as file descriptor in the
global uloop and dispatch received signals to the VM instance.
This ensures that the respective managed ucode signal handlers are
invoked immediately and not just after `uloop_run()` returns.
Also end the uloop in case any invoked signal handler threw an
exception, to match the expected behaviour with other kinds of
callbacks.
