dnsdist: Prevent a crash with DynBPF objects in client mode #10095

merged 1 commit into from Feb 17, 2021


Copy link

Short description

Since we return a nullptr object in client mode, we need to check that the object is valid in all methods and we forgot to do that in addBPFFilterDynBlocks, excludeRange() and includeRange().

Fixes #10090.
