This PR:

  • Adds support for POSIX O_CLOFORK (close-on-fork) flag.
  • Extends the concept to close_range()

This one looks perhaps deceptively simple to implement but it's passing all 667 tests (except dup3) from a suite adapted from Illumos not included yet.

This may be useful for Golang & Rust:

This interface was called stupid by opinionated Linux folks and perhaps they're right, so I want an informed opinion before going any further. I had my fun anyway. Here are the relevant links with discussion:

DONE

  • Add the adapted CDDL-licensed oclo tests. All 791 PASSED, 0 failed or skipped.
  • Support it in dup3
  • Add it in libsysdecode
  • Update manpages.

NOT NEEDED

  • "f" in fopen. It's not POSIX and not even Solaris/Illumos implement it.

NOTES

  • Except for manpages, this patch applies cleanly on FreeBSD 14

To test:

cd /usr/src/tests/oclo
make
sudo make install
/usr/tests/cddl/oclo/oclo
/usr/tests/cddl/oclo/oclo_errors

Thank you for taking the time to contribute to FreeBSD!
There is an issue that needs to be fixed:

This interface was called stupid by opinionated Linux folks and I want an informed opinion before going any further.

Skimming the thread, the main objection seems to be that the feature adds extra memory accesses to certain hot paths. I think this is not so true in our case, we already pay some of these overheads. We have 7 bits available for per-fd flags (struct filedescent is pretty fat anyway since it stores capsicum rights), and we already have to iterate over fds upon fork since kqueue descriptors implicitly have O_CLOFORK set.

XNU seems to implement this flag as well. I don't have strong feelings on whether it's very useful or not, but at a glance the implementation doesn't look too complex.

I do share the sentiment that the feature is silly. But the implementation should be straighforward, since the main pain point is fdcopy() where we already do the pass over all fds in the parent.

IMO it should be finished if only to have a checkpoint for POSIX compliance.

CDDL-licensed code from illumos should be placed under cddl/contrib/opensolaris. It's ok for the build outputs to be installed under /usr/tests, but the code should be excluded from the build if WITHOUT_CDDL= is defined in src.conf.

The build is not done automatically. To test:

make
sudo make install
/usr/tests/bin/oclo

The oclo_errors test shows some failures in socket because we don't check type in kern_socket:

CDDL-licensed code from illumos should be placed under cddl/contrib/opensolaris. It's ok for the build outputs to be installed under /usr/tests, but the code should be excluded from the build if WITHOUT_CDDL= is defined in src.conf.

The build is not done automatically. To test:

cd /usr/src/cddl/contrib/opensolaris/tests/oclo
make
sudo make install
/usr/tests/bin/oclo

Why not build it automatically? If it's not connected to the build, we won't catch regressions easily.

It now builds but doesn't run automatically because oclo_errors fails for the reason stated above.

It's ok to modify the test code to add or exclude checks, typically with #ifdef __FreeBSD__.

I just used #if 0 since the adaptation to FreeBSD was done on a separate commit and people can quickly check the changes.

I see the checkworld target uses kyua but this test is different. What do you suggest here?

This is basically the thing that I very much hate about dup3(), you get 2^n ops when you start adding flags. I do not think this part is sustainable. Some scalable design is needed there.

A possible solution is to define some new fcntl op with a code, say F_DUP3 23. Then, if none of the direct comparision of fcntl op with existing ops succeeds, we mask out top 16 bits from ops and see if result is eq to F_DUP3. If it is, then top 16 bits are interpreted as flags, and we put there CLOEXEC, your new CLOFORK, and have 14 more bits to tweak fd flags if any are grown.

I implemented your proposal, which is better than using CLOBOTH. All the tests are passing.

The only downside is that the semantics of F_DUP3FD are not fully compatible with Illumos' since we have to do fcntl(old, F_DUP3FD, | (flags << 16), new) instead of fcntl(old, F_DUP3FD, new, flags). But this flag is not POSIX anyway.

Why do we still need this command?

To have the close-on-fork equivalent of F_DUP2FD_CLOEXEC, as Illumos does.

You did not even responded to my note about F_DUP2DF_CLOFORK. I think everything but this is fine.

Rebased to take uexterr_gettext into account. Can we merge?

You did not even responded to my note about F_DUP2DF_CLOFORK. I think everything but this is fine.

I did above:
#1698 (comment)

To have the close-on-fork equivalent of F_DUP2FD_CLOEXEC, as Illumos does.

And you you ignored the later feedback where I said that this should not be done this way.

Where is it? Your feedback was about dup3() and I made the changes.

The rationale for F_DUP2FD_CLOFORK is the same for F_DUP2FD_CLOEXEC: compatibility with Solaris & Aix.
