--- Comment #9 from Arnd Bergmann <arnd at linaro dot org> ---
One more instance got added to the kernel today:
In file included from /git/arm-soc/include/trace/perf.h:90,
from /git/arm-soc/include/trace/define_trace.h:97,
from /git/arm-soc/include/trace/events/fscache.h:537,
from /git/arm-soc/fs/fscache/internal.h:32,
from /git/arm-soc/fs/fscache/main.c:20:
/git/arm-soc/include/trace/events/fscache.h: In function
'perf_trace_fscache_netfs':
/git/arm-soc/include/trace/events/fscache.h:200:1261: warning: 'strncpy'
specified bound 8 equals destination size [-Wstringop-truncation]
TRACE_EVENT(fscache_netfs,
Same as the one from comment #5, this one happen for -fsanitize=kernel-address
and is based on simple code that we don't warn for without sanitizer:
strncpy(__entry->name, netfs->name, 8);
__entry->name[7] = 0;
I can probably work around that by turning off -Wstringop-truncation whenever
sanitizers enabled in the kernel configuration (we already do that for
-Wmaybe-uninitialized), if this one is unlikely to get fixed before the gcc-8
release.
