>From 3bdb494aa2be26ed2b8ba9115994fd5f4939d5fa Mon Sep 17 00:00:00 2001 From: Sung-Jin Park <[email protected]>
Date: Mon, 11 Jan 2016 18:51:21 +0900 Subject: [PATCH] server: Add an API to get the socket fd for a client This adds an API to get the socket fd for a client. The client socket fd can be used for a wayland compositor to validate a request from a client. For instance, this will be helpful in some linux distributions, in which SELinux or SMACK is enabled. In those environments, each file (including socket) will have each security context in its inode as xattr member variable. A wayland compositor can validate a client request by getting socket fd of the client and by checking the security context associated with the socket fd.
