Date: Thu, 9 Jul 1998 23:26:44 -0500 (CDT) From: "Brent J. Nordquist" <bjn@visi.com> To: freebsd-alpha@FreeBSD.ORG Subject: Alpha S/Key fixed/verified Message-ID: <199807100426.XAA27506@thumper.visi.com>
index | next in thread | raw e-mail
I have fixed/verified the following:
lib/libmd ? [MD4 and MD5 seem to work]
lib/libskey Green
usr.bin/key Green
usr.bin/keyinfo Green [bright green--it's a perl script :-)]
usr.bin/keyinit Green
I've tested the S/Key tools, verified that they're interoperable with the
i386 ones (see below), and verified that S/Key authentication works in su.
(I expect login and ftpd to work also; on the list for tomorrow.)
Enclosed are the following:
(1) A patch to lib/libskey/skeysubr.c -- u_long was used to select a
32-bit quantity, which breaks on the Alpha. I'm sure we're going to
see a lot of these. Do we have an agreed-on method of handling them?
(Is there a type that's mapped to 32 bits on all systems, or are we just
going to use unsigned int as that type?) If there's a type that should
be used, then this patch should change.
(2) A patch to usr.bin/keyinit/skeyinit.c -- FreeBSD's gethostname()
will give you as many characters as it can, given the limit of the
passed buffer. NetBSD's gethostname() returns -1 if the full name
won't fit. This patch solves the problem, and seems like a good idea
in general, apart from the Alpha effort (it's much more consistent with
how gethostname() is handled in su, login, etc.).
(3) A patch to usr.bin/su/Makefile -- was missing -lmd after -lskey
(non-Alpha-specific, but tripped us up:)
(4) A patch to lib/libskey/Makefile -- is the comment below because
of the MD4 unresolved links, above? MD5 was probably being found in
-lcrypt, and that's why it worked whereas MD4 needed -lmd.
revision 1.12
date: 1998/05/11 09:15:03; author: jb; state: Exp; lines: +6 -1
[...]
And for some reason, alpha needs MD5. Find that out later!
I changed the Makefile back to use MD4 like i386 does, and ended up with
a set of key* tools that are interoperable with my i386 box. I think
this is a desirable goal.
