Subject: [PATCH v2 0/2] Documentation/admin-guide: introduce perf-security.rst
file and extend perf_event_paranoid documentation
To facilitate informed decision making by system administrators [1]
to permit and manage access to Perf Events (perf_events) / Perf tool (Perf) [2],[3]
performance monitoring for multiple users perf-security.rst document
suggested by Thomas Gleixner is introduced [4] that:
a) states perf_events/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 perf_events/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) perf_events/Perf usage models and its security implications
b) perf_events/Perf user interface, its changes and related security implications
c) security related implications of monitoring by a specific perf_events PMU [2]
