With the latest Samba 4.11.1 in Debian testing, writing one of these older files with a resource fork larger than 64K results in the resource fork portion getting truncated to 65454 bytes on the server end. This corrupts old Mac files with resource forks larger than 64K-- executables are the most affected by this, but graphic files such as PICT are too.

I don't have any MacOS systems anywhere around to test this.

Is this still an issue with current samba -- 4.13 in bullseye or
4.16 in bookworm and bullseye-backports?
