Subject: [PATCH] efi/http: Export {fw,http}_path variables to make them global
|
|
|
|
The fw_path environment variable is used by http_configure() function to
|
|
determine the HTTP path that should be used as prefix when using relative
|
|
HTTP paths. And this is stored in the http_path environment variable.
|
|
|
|
Later, that variable is looked up by grub_efihttp_open() to generate the
|
|
complete path to be used in the HTTP request.
|
|
|
|
But these variables are not exported, which means that are not global and
|
|
so are only found in the initial context.
|
|
|
|
This can cause commands like configfile that create a new context to fail
|
|
because the fw_path and http_path variables will not be found.
|
|
