[Samba] Samba 413 and 416 fail to receive/write 17TB file with NT_STATUS_INVALID_PARAMETER error

[Dave Baukus]

On FreeBSD stable 13.1 and 13.2 with samba 413 and 416, I consistently get this error when attempting to write a 17TB file to the samba server:

It consistently happens at offset 16TiB - 1MiB:
16 * (1024**4) = 17,592,186,044,416
Failed Offset from above: 17,592,184,995,840
17,592,186,044,416 - 17,592,184,995,840 = 1,048,576

I cannot find any useful references to any such issue.
Any clues or references that might help be track this down would be appreciated.
