Bug#920552: procps: Enable regular file and FIFO protection

Show all headers | View raw

Package: procps
Version: 2:3.3.15-2
Severity: normal

In analogy with bug #889098, procps should by default enabling the regular file
and FIFO protection added in 4.19 by setting:

fs.protected_regular = 1
fs.protected_fifos = 1

This will be done by default in systemd 241, but as Debian does not use
Systemd's sysctl settings, it should be made in procps.
