The closefrom() call, available in Solaris, is present in NetBSD since version 3.0. It is implemented with the F_CLOSEM fcntl() available since version 2.0.
These 2 fcntl would be cool to have in FreeBSD: F_CLOSEM Close all file descriptors greater than or equal to fd. F_MAXFD Return the maximum file descriptor number currently open by the process. I know that by using kern.file sysctl I could implement both, but it'd be nice if the whole closefrom() is done in kernel space. Another problem with using kern.file is that "struct xfile" may change... By checking http://fxr.watson.org/fxr/ident?v=NETBSD4;i=F_MAXFD I see that it's fairly straightforward to add the F_MAXFD bit. For the F_CLOSEM fcntl, which call is the best to replace the fdrelease() used by NetBSD in kern/kern_descrip.c ? Can someone add these to FreeBSD ?
