979535 - Cannot open unix domain sockets in abstract namespace

Status: RESOLVED DUPLICATE of bug 1462019

(Core :: Networking, defect, P5)

Description

[Christoph Grenz]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:27.0) Gecko/20100101 Firefox/27.0 (Beta/Release)
Build ID: 20140218140359

Steps to reproduce:

There is currently no way to open an abstract unix domain socket on Linux from Javascript extension code, as neither nsFile doesn't accept a path starting with a nul-byte and nsSocketTransportService.createUnixDomainTransport offers no flag to specify opening in the abstract namespace.

const FileFromPath = CC("@mozilla.org/file/local;1", "nsILocalFile", "initWithPath");
var file = FileFromPath('\0/tmp/socket');
var socket = socketTransportService.createUnixDomainTransport(file);




Actual results:

I get an error on FileFromPath('\0/tmp/socket'):
NS_ERROR_FILE_UNRECOGNIZED_PATH: Component returned failure code: 0x80520001 (NS_ERROR_FILE_UNRECOGNIZED_PATH) [nsILocalFile.initWithPath]

[Christoph Grenz]

The problem still exists.

My reason for this is a DBus implementation I wrote in Javascript ( https://gitlab.com/cg909/xpi-dbus ). The DBus session bus on Linux uses abstract domain sockets by default, so I had to work around this bug by executing socat to proxy the bus connection.
