mentioned repeatedly as a non-MP-safe driver that is hard to maintain,
and no one is taking care of it.
LMC was removed from OpenBSD three years ago, and from FreeBSD a few
months ago.
It works by tainting memory sources with marker values, letting the data
travel through the kernel, and scanning the kernel<->user frontier for
these marker values. Combined with compiler instrumentation and rotation
of the markers, it is able to yield relevant results with little effort.
We taint the pools and the stack, and scan copyout/copyoutstr. KLEAK is
supported on amd64 only for now, but it is not complicated to add more
architectures (just a matter of having the address of .text, and a stack
unwinder).
A userland tool is provided, that allows to execute a command in rounds
and monitor the leaks generated all the while.
KLEAK already detected directly 12 kernel info leaks, and prompted changes
that in total fixed 25+ leaks.
Based on an idea developed jointly with Thomas Barabosch (of Fraunhofer
FKIE).
when multiplying by 128 (in 32 bits, 128 * GIG == 0)
Should fix i386 build )and other 32 bit ports).
An alternative would be to use ULL rather than UL for the numbers,
but that would mean needlessly doing 64 bit arith for data that is
resticted to 32 bit results anyway.
- publish per-cpu data
- publish a whole bunch of info in struct aarch64_sysctl_cpu_id
instead of various individual nodes (there are 16 total.)
- add MIDR extractor bits
- define ARMv8.2-A id_aa64mmfr2_el1 and id_aa64zfr0_el1 regs,
but avoid using them until we make sure they exist. (these
members are added to aarch64_sysctl_cpu_id to avoid future
compat issues.)
the arm32 and aarch32 version of these need to be adjusted as
well (and aarch32 data published at all.) still trying to
work out how to make the same userland binary running on a
real arm32 or an aarch32 system can work sanely here.
ok ryo@.
Skip CDs when looking for install targets (we do not support installing
onto a blueray with UDF).
Fix search for the default CDROM device and the CD we booted from
for ports with nonstandard CDROM device names.
