src/sys/netinet6: scope6.c
Log Message:
Decorate in6_clearscope() with __noubsan
sys/netinet6/scope6.c:480:6,
member access within misaligned address 0xffff9457bc441286 for type
'struct in6_addr' which requires 4 byte alignment
This issue is caused by accessing non-__packed struct in __packed.
This is a[always?] false-positive reported by the sanitizer and there is no
clear non-invasive approach to handle this, without changing ABI of long
term existing code.
