smbd/vfs.c:
Added fchmod and fchown to VFS (sorry Gerald - but we needed them anyway).
smbd/dosmode.c:
smbd/files.c:
printing/printfsp.c:
smbd/close.c:
smbd/open.c:
Fixed "dos filemode" correctly so there are no race conditions. Forces test
of open of file O_WRONLY before allowing fchmod as root. Afterwards, calls
standard close function that preserves POSIX locks due to POSIX-me-harder
braindamage. :-). Andrew please review this code.
Also - in removing the tmpdir param in smbrun an extra NULL parameter
was missed in each print_run_command() call (which is a varargs fn.).
Now fixed.
Jeremy.
