Hi Bernhard,
Following your "statfs: support f_frsize" commit a couple of days ago,
statvfs is broken. Here's a little poc:
#include <sys/statvfs.h>
int main() {
struct statvfs mystat;
statvfs("/usr/portage/distfiles", &mystat);
return 0;
}
which dies with
*** stack smashing detected ***: ./poc terminated
Killed
Looks like buf->__f_spare is not getting properly zeroed at line 48 of
libc/misc/statfs/internal_statvfs.c. Reverting to 6 ints fixes it:
- memset (buf->__f_spare, '\0', sizeof(fsbuf.f_spare));
+ memset (buf->__f_spare, '\0', 6 * sizeof(int));
