[bitbake-devel] [PATCH 1/1] bitbake: toaster: settings set ALLOWED_HOSTS to * in debug mode

[brian avery]

This is a backport of 7c3a47ed8965c3a3eb90a9a4678d5caedbba6337

>From the commit to master:
As of Django 1.8.16, Django is rejecting any HTTP_HOST header that is
not on the ALLOWED_HOST list.  We often need to reference the toaster
server via a fqdn, if we start it via webport=0.0.0.0:8000 for instance,
and are hitting the server from a laptop. This change does reduce  the
protection from a DNS rebinding attack, however, if you are running the
toaster server outside a protected network, you should be using the
production instance.

+# Update as of django 1.8.16 release, the '*' is needed to allow us to connect while running
+# on hosts without explicitly setting the fqdn for the toaster server.
+# See https://docs.djangoproject.com/en/dev/ref/settings/ for info on ALLOWED_HOSTS
+# Previously this setting was not enforced if DEBUG was set but it is now.
+# The previous behavior was such that ALLOWED_HOSTS defaulted to ['localhost','127.0.0.1','::1']
+# and if you bound to 0.0.0.0:<port #> then accessing toaster as localhost or fqdn would both work.
+# To have that same behavior, with a fqdn explicitly enabled you would set
+# ALLOWED_HOSTS= ['localhost','127.0.0.1','::1','myserver.mycompany.com'] for
+# Django >= 1.8.16. By default, we are not enforcing this restriction in
+# DEBUG mode.
+if DEBUG is True:
+    # this will allow connection via localhost,hostname, or fqdn
+    ALLOWED_HOSTS = ['*']
