There is an equivalent structure, struct ipoption in ip_var.h
which is actually used in various parts of the kernel, and also referenced
in Stevens.
Bill Fenner also says:
... if you want the trivia, struct ip_opts was introduced
in in.h SCCS revision 7.9, on 6/28/1990, by Mike Karels.
struct ipoption was introduced in ip_var.h SCCS revision 6.5,
on 9/16/1985, by... Mike Karels.

bug in lib/libc/gen/basename.c rev 1.1. There is no way for us to test
what revision of basename() we have in libc, thus this change.

PRISON_ROOT to the suser_xxx() check. Since securelevels may now
be raised in specific jails, use of system flags can still be
restricted in jail(), but in a more configurable way.
o Users of jail() expecting system flags (such as schg) to restrict
jail()'s should be sure to set the securelevel appropriately in
jail()'s.
o This fixes activities involving automated system flag removal in
jail(), including installkernel and friends.

securelevel_gt(), determine first if a local securelevel exists --
if so, perform the check based on imax(local, global). Otherwise,
simply use the global value.
o Note: even though local securelevels might lag below the global one,
if the global value is updated to higher than local values, maximum
will still be used, making the global dominant even if there is local
lag.

one is present in the current jail, otherwise, to return the global
securelevel.
o If the securelevel is being updated, require that it be greater than
the maximum of local and global, if a local securelevel exists,
otherwise, just maximum of the global. If there is a local
securelevel, update the local one instead of the global one.
o Note: this does allow local securelevels to lag behind the global one
as long as the local one is not updated following a global increase.

a time change, and callers so that they provide td->td_proc.
o Modify settime() to use securevel_gt() for securelevel checking.

Restore the code that avoided closing and reopening
stdin. This is also required by POSIX. As a bonus,
enable multiple stdin reads with the -benstv flags,
by resetting the EOF condition on stdin.
