- In order to get all three LinuxRT variants to have ALL of the features functional the following needs to be done:
- Ensure that BusyBox is configured such that telnet is disabled entirely (neither set nor enabled)
- Ensure that BusyBox is configured such that SUID is enabled (set and enabled)
- The starting point of the BusyBox config file comes from site/config/bb-1.25.x.config, which you need copy from the .config you construct from running
make busybox-menuconfig . For 2019-08 it's site/config/bb-1.29.x.config. This file is set in the BR2_PACKAGE_BUSYBOX_CONFIG which is in the br-2016.11.1-common.config file (for 2019-08, it's in site/br2-external/configs/br-common.config). - Ensure that BuildRoot is configured such that the password method is sha-256 instead of md5:
- The way you do this is via
make menuconfig . It's part of the "System Configuration" changes – you switch from either MD5 or SHA-256 via the menu it provides. - Once that is complete, the top-level .config file is changed with that change. You can then diff this with .config.old.
- Once you know the specific differences, you add those changes to the bottom of the common.config file – in 2016-11.1, this is in the site/config directory; in 2019-08, this in the site/br2-external/configs directory.
- Although Eric didn't check them in yet, the rest of the changes in his site directory (which are essentially all of the changes that go into the RFS itself) work as expected (these are the changes for all of the user/groups and the /etc/SLACproperties file).
- Note: I checked in changes to both the br-2019-08-dev and br-2016-11-dev buildroot-site branches that contain the base changes for an RC4 build.
To test the chrt changes, you can do something along the lines of this:
