Subject: [RFC] FUSE: support for file_flags and birthtime (FreeBSD use case)
Date: Fri, 20 Mar 2026 14:36:40 +0530	[thread overview]
Message-ID: <CABR4S-vSW7qpvBfUrARtfgc91iF=PZPQNHvd0Xc=iiK=mx79vQ@mail.gmail.com> (raw)

Hi all,

I’m a new contributor working on improving fusefs in FreeBSD, and I'm
bringing up an issue in FUSEFS.

FreeBSD supports file flags modification with chflags(2) and file
creation time (st_birthtime) at the VFS level. But, these are not
currently supported by the FUSE protocol.
As a result, fusefs on FreeBSD cannot expose or preserve these attributes.

I think we need to append struct fuse_attr with:
uint32_t file_flags;
uint64_t birthtime;
uint32_t birthtimensec;
Handling them in a backward compatible way.

Is extending fuse_attr in this way acceptable? If so, I’d be happy to
make the changes and follow up with a patch.


Thanks
- Raghav
