@@ -22,6 +22,18 @@ Recipe changes
recipes now need to use ``;protocol=https`` at the end of GitHub
URLs. The same script as above can be used to convert the recipes.
- Network access from tasks is now disabled by default on kernels which support
this feature (on most recent distros such as CentOS 8 and Debian 11 onwards).
This means that tasks accessing the network need to be marked as such with the ``network``
flag. For example::
do_mytask[network] = "1"
This is allowed by default from ``do_fetch`` but not from any of our other standard
tasks. Recipes shouldn't be accessing the network outside of ``do_fetch`` as it
usually undermines fetcher source mirroring, image and licence manifests, software
auditing and supply chain security.
- The :term:`TOPDIR` variable and the current working directory are no longer modified
when parsing recipes. Any code depending on that behaviour will no longer work.
