Subject: torture: add smb2 FSCTL_[GET/SET]_COMPRESSION test
X-Git-Url: http://git.samba.org/?p=metze%2Fsamba%2Fwip.git;a=commitdiff_plain;h=d944841211a407c3587ccabd3615df55fba72aaf

torture: add smb2 FSCTL_[GET/SET]_COMPRESSION test

This test simply creates a file and checks the compression state before
and after FSCTL_SET_COMPRESSION(COMPRESSION_FORMAT_DEFAULT).

The test expects the compression state to be COMPRESSION_FORMAT_LZNT1
after set, conforming to Windows Server behaviour.

If the server responds to the first FSCTL_GET_COMPRESSION request with
NT_STATUS_NOT_SUPPORTED or NT_STATUS_INVALID_DEVICE_REQUEST, then the
test is skipped. This allows it to run during selftest.
