Summary

The LinearBoostController::getBoostAmount function may return zero due to integer division truncation when the product of _amount, maxBoost, and _lockingDuration is less than maxLockingDuration.

This can occur when staking with small amounts or for short locking durations, which should still result in a staker getting credited a non-zero boost.

Impact

Stakers will not be credited for a boost when they should be.

Recommendations

Consider implementing a minimum staking amount and/or lockDuration so it is not possible for a user to "lock" tokens and not receive a boost in rewards.
