Just checked the source code of setcap and found that it does not support large
files.
Consider the following code in cap_file.c/cap_set_file:
...
struct stat buf;
if (lstat(filename, &buf) != 0) {
_cap_debug("unable to stat file [%s]", filename);
return -1;
}
...
If it is built on 32-bit linux, this code will not work for files large than
2Gb, because lstat() uses stat structure which represents size of file as off_t
type.
As a workaround I suppose _LARGEFILE64_SOURCE and _FILE_OFFSET_BITS=64 can be
defined during compilation.
