perf: Fix strncpy() use, always make sure it's NUL terminated For NUL terminated string, always make sure that there's '\0' at the end. In our case we need a return value, so still use strncpy() and fix up the tail explicitly. (strlcpy() returns the size, not the pointer) Signed-off-by: Chen Gang <gang.c...@asianux.com> Cc: a.p.zijls...@chello.nl <a.p.zijls...@chello.nl> Cc: pau...@samba.org <pau...@samba.org> Cc: a...@ghostprotocols.net <a...@ghostprotocols.net> Link: http://lkml.kernel.org/r/51623e0b.7070...@asianux.com Signed-off-by: Ingo Molnar <mi...@kernel.org> --- kernel/events/core.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/kernel/events/core.c b/kernel/events/core.c index 59412d0..7f0d67e 100644 --- a/kernel/events/core.c +++ b/kernel/events/core.c @@ -4737,7 +4737,8 @@ static void perf_event_mmap_event(struct perf_mmap_event *mmap_event) } else { if (arch_vma_name(mmap_event->vma)) { name = strncpy(tmp, arch_vma_name(mmap_event->vma), - sizeof(tmp)); + sizeof(tmp) - 1); + tmp[sizeof(tmp) - 1] = '\0'; goto got_name; } -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
