The BUGS note simply means that a pipe has a unique inode number, which is what we want. So that's not indicating any problem. Oh, I see the problem now. For a socket or pipe, macOS fstat returns the full 64-bit inode number, whereas macOS stat returns only the low order 32 bits. In your example, 3009428657538693161 % (2**32) == 1568241705. This is a kernel bug in macOS. Can you report it or otherwise arrange to have the kernel bug fixed? I expect that you have better connections with Apple than I do. A proposed patch (relative to xnu-10063.101.15) is attached; I have not tested it as I don't use macOS. Thanks. Also, I am documenting this macOS bug in Gnulib by installing the second attached patch to Gnulib, and am cc'ing this email to bug-gnulib. --------------RxIpgs5yJQ7Ef9ZqNxCm10Nt Content-Type: text/x-patch;

How is a macOS program supposed to tell whether a file has been changed between stat and open? Is it impossible?

I disagree. I think coreutils should not try to work on broken systems;
especially when the checks are done for security reasons. Let the
system die.

I debugged it a bit more locally and it looks like it's a known
limitation of fstat()/stat() mismatch on FIFOs on Darwin. Example
program:
$ cat simple.c
#include <sys/stat.h>
#include <assert.h>
#include <sys/fcntl.h>
#include <unistd.h>
#include <stdio.h>
int main() {
struct stat s;
int fd;
int r;
fd =3D open("/dev/fd/0", O_RDONLY);
assert(fd > 0);
r =3D fstat(fd, &s);
assert(r =3D=3D 0);
fprintf(stderr, "1: ino=3D%llu\n", s.st_ino);
close(fd);
fd =3D open("/dev/fd/0", O_RDONLY);
assert(fd > 0);
r =3D fstat(fd, &s);
assert(r =3D=3D 0);
fprintf(stderr, "2: ino=3D%llu\n", s.st_ino);
close(fd);
r =3D stat("/dev/fd/0", &s);
assert(r =3D=3D 0);
fprintf(stderr, "3: ino=3D%llu\n", s.st_ino);
close(fd);
}
Running:
$ clang simple.c -o simple && echo 42 | ./simple
1: ino=3D3009428657538693161
2: ino=3D3009428657538693161
3: ino=3D1568241705
Note how stat() and fstat() don't agree on inode.
Apparently it's documented in
https://developer.apple.com/library/archive/documentation/System/Conceptual=
/ManPages_iPhoneOS/man2/fstat.2.html
as
BUGS
Applying fstat to a socket (and thus to a pipe) returns a zero'd buffe=
r,
except for the blocksize field, and a unique device and inode number.
Perhaps coreutils should avoid inode checks on FIFOs and sockets. They
are already volatile by nature.

I see that merit too, as when 'install' reads from stdin it needn't do=20 the inode check. However, POSIX requires 'cp - X' to copy a file named=20 '-' to X; cp cannot copy from stdin. Although POSIX doesn't specify=20 'install', there is some value to having 'install' behave like 'cp'. I suppose we could have install special-case "/dev/stdin", on platforms=20 where /dev/stdin is known to mean standard input. Seems like a bit much=20 to work around a Darwin kernel bug, though.

I think /dev/stdin is a good name for stdin. It should work everywhere, and if not the system is broken, in which case, I'd rather fix the system than adding a slightly different special case for - in every program. Of course there are systems one can't fix, like Solaris... Commands that special-case - I always need to remember, and check the docs. But it's a personal opinion, and I don't feel too strongly about it. Have a lovely night!

It'd have to be pretty old. As near as I can see from xnu/bsd/kern/sys_pipe.c, the st_ino field was zero (i.e., not random) even in xnu-792 dated 2005. I'd be leery of changing this part of coreutils/src/copy.c without knowing more about exactly why bug occurs on (older?) Darwin, as weakening the check would make GNU 'install' easier to attack.

The version I tested on is 3 years old now though, so I'm not sure whether the issue is on newer or older. Note we had similar issue on Solaris, where we used an fstat() wrapper to adjust things: https://bugs.gnu.org/35713 A related suggestion was from Marc Chantreux (CC'd) to support '-' to imply stdin, which would be more portable. There is some merit to that suggestion too. cheers, Pádraig

I don't know. The reporter didn't tell. I see you also asked on the
Github original report.

Hmmmm. Since you couldn't reprodude it in a recent Darwin, maybe it's
just a bug in an old Darwin. And since noone else seems to have met
this Darwin's bug, maybe we can just ignore it. (And if it were a
regression in a more recent Darwin, hopefully they should fix their
kernel.)
I'm not happy relaxing a security check, without making sure that there
are no implications at all.
I vote for claiming only limited support to such a Darwin system. I
already workarounded it in the Linux man-pages, by not piping to
install(1) in a common task; and nobody else seems to be affected.
Unless you feel confident that it's perfectly fine to do it. But I have
no sympathy for workarounding Darwin bugs here.
Have a lovely day!

Note that check originally came from:
https://github.com/coreutils/coreutils/commit/dea4262fa
I suppose we could relax the check as follows, for files of apparent size 0
which would cater for this, and others that may also have unstable inodes.

I can't repro on Darwin 21.6.0 (MacOSX 12.6). The issue seems to be that /dev/stdin returns a varying inode which install(1) doesn't like currently cheers, Pádraig

I don't own a Darwin system, so I can't help much reproduce. However, I've received a bug report to the Linux man-pages, that our build system (GNUmakefile-based), which ends up calling ... | install /dev/stdin $@ doesn't work on Darwin. Here's the original bug report: <https://github.com/NixOS/nixpkgs/pull/300797>. Here are the reported error messages: =2E.. INSTALL /nix/store/3s28l9ijlkmsq8256zdxjvl173gkn37c-man-pages-6.7/s= hare/man/man3/addseverity.3 INSTALL /nix/store/3s28l9ijlkmsq8256zdxjvl173gkn37c-man-pages-6.7/s= hare/man/man3/adjtime.3 install: skipping file '/dev/stdin', as it was replaced while being copied make: *** [share/mk/install/man.mk:54: /nix/store/3s28l9ijlkmsq8256zdxjvl17= 3gkn37c-man-pages-6.7/share/man/man3/addmntent.3] Error 1 make: *** Waiting for unfinished jobs.... install: skipping file '/dev/stdin', as it was replaced while being copied make: *** [share/mk/install/man.mk:54: /nix/store/3s28l9ijlkmsq8256zdxjvl17= 3gkn37c-man-pages-6.7/share/man/man3/acosh.3] Error 1 install: skipping file '/dev/stdin', as it was replaced while being copied install: skipping file '/dev/stdin', as it was replaced while being copied install: skipping file '/dev/stdin', as it was replaced while being copied =2E.. I don't see why install(1) should fail to read /dev/stdin under any POSIX system.
