["Manuel Bouyer" <bouyer%netbsd.org@localhost>]

Module Name:    src
Committed By:   bouyer
Date:           Sun May 24 17:43:18 UTC 2026

Modified Files:
        src/sys/external/bsd/ipf/netinet: ip_fil_netbsd.c

Log Message:
Explicitely check a pointer against NULL before computing a member address,
to avoid undefined behavior. Avoids the same NULL pointer check being
"optimised" later, leading to NULL pointer dereference.
It is expected that -fno-delete-null-pointer-checks would avoid this but
it does not.
