Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Memory Corruption: Misalignment between Rust's standard library representation of SocketAddr and C layouts led to potential memory corruption and undefined behavior when calling from_raw_parts. Developers must avoid assuming layout equivalence between std structures and C system structures.

Memory Corruption: Constructing Socket references from invalid raw descriptors can lead to undefined behavior due to Rust's niche optimization assumptions. Strong assertions on descriptor validity must be enforced during raw conversion boundaries.
