r17541: When returning a trans2 request, if the "max data
bytes returned" is less than the amount we want
to send, return what we can and set STATUS_BUFFER_OVERFLOW
(doserror ERRDOS,ERRbufferoverflow). Required by
OS/2 to handle EA's that are too large. It's hard
to test this in Samba4 smbtorture as the max data
bytes returned is hard coded at 0xffff (as it is
in the Samba3 client libraries also). I used a
custom version of Samba4 smbtorture to test this
out. Might add a "max data bytes" param to make
this testable in the build farm. Confirmed by
"Guenter Kukkukk (sambaos2)" <sambaos2@kukkukk.com>
and Andreas Taegener <atsamba11@eideltown.de>
that this fixes the issue.
