From e55ec845e6ed889a43c14c72ddb9183e0b87c60b Mon Sep 17 00:00:00 2001 From: Michael Brown Date: Tue, 26 Jan 2016 16:16:13 +0000 Subject: [uri] Apply URI decoding for all parsed URIs The various early-exit paths in parse_uri() accidentally bypass the URI field decoding. The result is that opaque or relative URIs do not undergo URI field decoding, resulting in double-encoding when the URIs are subsequently used. For example: #!ipxe set mac ${macstring} imgfetch /boot/by-mac/${mac:uristring} would result in an HTTP GET such as GET /boot/by-mac/00%253A0c%253A29%253Ac5%253A39%253Aa1 HTTP/1.1 rather than the expected GET /boot/by-mac/00%3A0c%3A29%3Ac5%3A39%3Aa1 HTTP/1.1 Fix by ensuring that URI decoding is always applied regardless of the URI format.
