Subject: [PATCH] efi/http: Enclose literal IPv6 addresses in square brackets
|
|
|
|
According to RFC 2732 (https://www.ietf.org/rfc/rfc2732.txt), literal IPv6
|
|
addresses must be enclosed in square brackets. But GRUB currently does not
|
|
do this and is causing HTTP servers to send Bad Request (400) responses.
|
|
|
|
For example, the following is the HTTP stream when fetching a config file:
|
|
|
|
HEAD /EFI/BOOT/grub.cfg HTTP/1.1
|
|
Host: 2000:dead:beef:a::1
|
|
Accept: */*
|
|
User-Agent: UefiHttpBoot/1.0
|
|
|
|
HTTP/1.1 400 Bad Request
|
|
Date: Thu, 05 Mar 2020 14:46:02 GMT
|
|
Server: Apache/2.4.41 (Fedora) OpenSSL/1.1.1d
|
|
Connection: close
|
|
Content-Type: text/html; charset=iso-8859-1
|
|
|
|
and after enclosing the IPv6 address the HTTP request is successful:
|
|
|
|
HEAD /EFI/BOOT/grub.cfg HTTP/1.1
|
|
Host: [2000:dead:beef:a::1]
|
|
Accept: */*
|
|
User-Agent: UefiHttpBoot/1.0
|
|
|
|
HTTP/1.1 200 OK
|
|
Date: Thu, 05 Mar 2020 14:48:04 GMT
|
|
Server: Apache/2.4.41 (Fedora) OpenSSL/1.1.1d
