What do people think about having a range of bits in oid_kind that are
not used by FreeBSD but are only to be used by ``private'' sysctl handlers?
e.g.
#define CTLFLAG_PRIVATE 0x000ffff0
The idea is so you can do this:
#define SYSCTL_IPF(parent, nbr, name, access, ptr, val, descr) \
SYSCTL_OID(parent, nbr, name, CTLTYPE_INT|access, \
ptr, val, sysctl_ipf_int, "I", descr);
SYSCTL_IPF(_net_inet_ipf, OID_AUTO, fr_tcpidletimeout, CTLFLAG_RW|CTL_PRIV,
&fr_tcpidletimeout, 0, "");
and have CTL_PRIV be a bit which sysctl_ipf_int understands and not
have to worry about the value of CTL_PRIV ever being afflicted with
double-use by a FreeBSD flag because CTL_PRIV is part of CTLFLAG_PRIVATE.
Any objections to committing it to -current in the next week or so ?
Darren
