My smb.conf is pretty standard, except I have vfs enabled and samba was working until today when I upgraded my system

#### VFS ####
   vfs objects = catia fruit streams_xattr
   fruit:resource = stream
   fruit:metadata = stream

Looks like streams_xattr is broken, any thoughts ?

Samba 4.15.0, has completely rewritten vfs, so I figured something had to give.

There are no specific breaking changes mentioned in the release notes, but man vfs_fruit still mentions fruit:resource = stream as experimental and not recommened with streams_xattr

I've changed my vfs smb.conf to

#### VFS ####
min protocol = SMB2
vfs objects = fruit streams_xattr
fruit:aapl = yes
# fruit:resource = stream
fruit:metadata = stream

Tried deleting, viewing and adding files to a folder from my Mac and it seems to be working fine.

I'll keep an eye on things
