* It relies on some hardware clock mechanism that may not available on all the

|
|
* time in the past; it is not correlated in any way to
|
|
* the time of day, and thus is not subject to resetting or
|
|
* drifting by way of adjtime or settimeofday. The hi-res
|
|
* timer is ideally suited to performance measurement
|
|
* tasks, where cheap, accurate interval timing is required.

* <b>IMPORTANT</b><br />
|
|
* The method to read the hard real-time clock on some architecture rely on
|
|
* calling the assembler-instruction "rdtsc". This has several drawbacks when
|
|
* used in a multi-core machine with scalable frequency or power management
|
|
* that may put one core to sleep (or slow down the clock).

|
* TRUST-756: Helper macro to prevent a pointer value from being speculated.
|
|
* It addresses the Spectre Variant 1 vulnerability in a platform independent
|
|
* way. The technique that we employ here is called Speculative Load Hardening.
|
|
*
|
|
* The events contributing to speculative execution in coverity typically start
|
|
* with an if/else/for/while block.
|
|
* Use this macro inside the block if the true branch is taken otherwise
|
|
* use it just outside the block by passing the condition by prepending it with
|
|
* !.
|
|
*
|
|
* For reference coverity will report something like this as the first
|
|
* contributing event for the issue:
|
|
* compare_value: Comparing <condition>
|
|
* Condition <condition>, taking true/false branch
|
|
* If the true branch is taken you would pass <condition> to this macro while
|
|
* using it inside the block.
|
|
* If the false branch is taken you would pass !<condition> to this macro while
|
|
* using it outside the block.
|
|
*
|
|
* @brief
|
|
* The basic idea to avoid speculative execution of an if/else/for/while block
|
|
* is to force the entry condition execution using a ternary operator. A ternary
|
|
* operator (or a conditional update) based assignment is guaranteed to be
|
|
* implemented in a branchless way on most modern architectures:
|
|
* https://llvm.org/docs/SpeculativeLoadHardening.html#high-level-mitigation-approach
|
|
*
|
|
* @details
|
|
* The AUDIT.SPECULATIVE_EXECUTION_DATA_LEAK checker from Coverity detects
|
|
* Spectre Variant 1 vulnerabilities. This is detailed in this blog post:
|
|
* https://www.synopsys.com/blogs/software-security/detecting-spectre-vulnerability-exploits-with-static-analysis.html
|
|
*
|
|
* This macro adopts the mitigation approach detailed in this post for Variant
|
|
* 1:
|
|
* https://llvm.org/docs/SpeculativeLoadHardening.html#high-level-mitigation-approach

|
* For more information about Spectre and Speculative Execution you can also
|
|
* read the paper: https://spectreattack.com/spectre.pdf
|
|
*
|
|
*
|
|
* @param pointer__
|
|
* The pointer to harden against speculative execution.
|
|
* This is typically reported by coverity under the second event contributing to
|
|
* the issue. It should be shown as 'compared_memory_access'.
|
|
*
|
|
* @param pointerType__
|
|
* The type used to cast the result from the ternary operator (conditional
|
|
* update).
|
|
*
|
|
* @param speculatedCondition__
|
|
* The condition that may be bypassed by speculation. For an if/else
|
|
* if/for/while block copy the same condition as is. For the else block copy the
|
|
* if condition by prefixing it with a !. This is typically reported by coverity
|
|
* as the first event contributing to the issue. It should be shown as
|
|
* 'compare_value'.
