Subject[PATCH v1 0/2]: Documentation/admin-guide: introduce perf-security.rst file and extend perf_event_paranoid documentation
Date

To facilitate informed decision making by system administrators [1]
to permit and manage access to PCL/Perf [2],[3] performance monitoring
for multiple users perf-security.rst document suggested by Thomas Gleixner
is introduced [4] that:

a) states PCL/Perf access security concerns for multi user environment
b) refers to base Linux access control and management principles
c) extends documentation of possible perf_event_paranoid knob settings

The file serves as single knowledge source for PCL/Perf security and
access control related matter according to decisions, discussion and
PoC prototype previously made here [5],[6].

The file can later be extended with information describing:

a) PCL/Perf usage models and its security implications
b) PCL/Perf user interface, its changes and related security implications
c) security related implications of monitoring by a specific PCL PMU [2]
