smbd: remove itime and file_id logic and code

2022-03-31T23:01:37+00:00

This bases File-Ids on the inode numbers again. The whole stuff was
added because at that time Apple clients

1. would be upset by inode number reusage and

2. had a client side bug in their fallback implemetentation that
assigns File-Ids on the client side in case the server provides
File-Ids of 0.

After discussion with folks at Apple it should be safe these days to
rely on the Mac to generate its own File-Ids and let Samba return 0
File-Ids.

s3:lib: round itime to NTTIME resolution in make_file_id_from_itime()

2019-09-10T19:05:29+00:00

The rounding is needed because when a file is created via eg an SMB2 CREATE
request, we need to calculate the correct File-ID for the QFID Create-Context or
for a subsequent GETINFO SMB request on the same file-handle.

Any later metadata request that received the File-ID will do so by going through
dos_mode() -> ... -> parse_dos_attribute_blob(), where the File-ID will be
calculated from the on-disk itime which has NTTIME resolution.

As long as that is the only available itime backend, I'm rounding itime inside
make_file_id_from_itime(), not in the callers.
