Subject: [GIT PULL] x86/misc changes for v5.9
Date: Mon, 3 Aug 2020 20:47:20 +0200 [thread overview]
Message-ID: <20200803184720.GA1230231@gmail.com> (raw)
Linus,
Please pull the latest x86/misc git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86-misc-2020-08-03
# HEAD: a7e1f67ed29f0c339e2aa7483d13b085127566ab x86/msr: Filter MSR writes
Filter MSR writes from user-space by default, and print a syslog entry if
they happen outside the allowed set of MSRs, which is a single one for now,
MSR_IA32_ENERGY_PERF_BIAS.
The plan is to eventually disable MSR writes by default (they can still be
enabled via allow_writes=on).
Signed-off-by: Ingo Molnar <mingo@kernel.org>
Thanks,
Ingo
