e05ec5c85f feat(variant1): detect vanilla mitigation 
Implement detection of mitigation for Variant 1 that is
being pushed on vanilla kernel.
Current name of the patch:
"spectre variant1 mitigations for tip/x86/pti" (v6)
Also detect some distros that already backported this
patch without modifying the vulnerabilities sysfs hierarchy.
This detection is more reliable than the LFENCE one, trust
it and skip the LFENCE heuristic if a match is found.

Move all the CPU checks to their own section,

RDCL_NO and IBRS_ALL. We also show whether the
system CPU is vulnerable to the three variants,
regardless of the fact that mitigations are in
place or not, which is determined in each vuln-
specific section.

have the sysfs vulnerability hierarchy and our heuristic to

for retpoline-aware compiler detection from UNKNOWN to NO.
When CONFIG_RETPOLINE is not set, a retpoline-aware compiler
won't produce different asm than a standard one anyway.

ff5c92fa6f feat(sysfs): print details even with sysfs 
Before, when the /sys kernel vulnerability interface
was available, we would bypass all our tests and just
print the output of the vulnerability interface. Now,
we still rely on it when available, but we run our
checks anyway, except for variant 1 where the current
method of mitigation detection doesn't add much value
to the bare /sys check
 2018-01-24 09:04:25 +01:00
Stéphane Lesimple
443d9a2ae9 feat(ibpb): now also check for IBPB on variant 2 
In addition to IBRS (and microcode support), IBPB
must be used to mitigate variant 2, if retpoline
support is not available. The vulnerability status
of a system will be defined as "non vulnerable"
if IBRS and IBPB are both enabled, or if IBPB
is enabled with a value of 2 for RedHat kernels,

40381349ab fix(dmesg): detect when dmesg is truncated 
To avoid false negatives when looking for a message
in dmesg, we were previously also grepping in known
on-disk archives of dmesg (dmesg.log, kern.log).
This in turn caused false positives because we have no
guarantee that we're grepping the dmesg of the current
running kernel. Hence we now only look in the live
`dmesg`, detect if it has been truncated, and report
it to the user.

4a2d051285 minor is_cpu_vulnerable() changes (#71) 
* correct is_cpu_vulnerable() comment

As far as I can tell, the function and usage are correct for the comment
to be inverted.

Add a clarifying note as to why the value choice makes sense.

* exit on invalid varient

If this happens, it's a bug in the script. None of the calling code
checks for status 255, so don't let a scripting bug cause a false
negative.

* no need to set vulnerable CPUs

According to comment above this code:
'by default, everything is vulnerable, we work in a "whitelist" logic here.'

bc4e39038a fix(opcodes): fix regression introduced in previous commit 
We were saying unknown instead of vulnerable when the count of lfence opcodes was low
This was not impacting batch mode or the final decision, just the human-readable output of the script.

52a8f78885 send warning to stderr. (#53) 
With --batch json there must not be any other output on stdout, so redirect warnings to stderr will show the warning on the console and only the json output is on stdout.
