start: remove procfs pidfd support · 01602949

authored Dec 25, 2019

We'll only rely on proper anon-inode based pidfd support in the future.
There's no good reason to use the procfs fallback. All the fancy features we
might want to use are only available with anon-inode pidfds.

Adaptation to latest busybox · 3daa49d8

authored Dec 27, 2019

In busybox 1.30, the help of udhcpc for "-s" option changed:
--> busybox v1.27.2: -s,--script PROG	Run PROG at DHCP events (default /usr/share/udhcpc/default.script)
--> busybox v1.30.1: -s PROG		Run PROG at DHCP events (default /etc/udhcpc/default.script)
So, I changed the command line which extracts the script name to make it work for both versions

cgroups/cgfsng: do not prematurely close file descriptors · 5d562424

authored Dec 12, 2019

When adding the new improved cgroup setup logic I didn't account for the fact
that we need the hierarchy fds up until chown. Add a dedicated cleanup method
to fix this:
