similar to: uid transition and post-auth privsep (WAS Re: possible fundamental problem with tru64 patch) (fwd)

A while back, I sent in a patch that added Digital Unix SIA authentication to OpenSSH. Well, I just figured out that it didn't handle everything correctly (locked accounts could still log in). I thought I had checked that, but I guess I missed it. Anyway, here is a patch against OpenSSH 2.2.0p1 that fixes this. -- Chris Adams <cmadams at hiwaay.net> Systems and Network Administrator

Is anyone maintaining the OSF_SIA support in openssh? This seems to be an obvious bug triggered if you try to connect as a non-existant user. >From auth1.c line 459 #elif defined(HAVE_OSF_SIA) (sia_validate_user(NULL, saved_argc, saved_argv, get_canonical_hostname(), pw->pw_name, NULL, 0, NULL, "") == SIASUCCESS)) { #else /*

Here is a long-overdue (sorry about that) patch for Tru64. It is pretty minor mostly (minor formatting and removal of a couple of unneeded calls), and it disables post-auth privsep (so that OpenSSH will work "out of the box" on Tru64, avoiding the many questions). I'm also looking at getting setproctitle working. For Tru64 4.x, it isn't a big deal (normal PS_USE_CLOBBER_ARGV

I have found the following patches to be desirable for using sshd on a Tru64 UNIX system with the Kerberos 5 SIA module (libsia_krb5.so) from Heimdal. These patches do the following: 1) preserve context between the password authentication and the session setup phases. This is necessary because the Heimdal SIA module stores Kerberos context information as mechanism-specific data in

Ok.. I need wider testing for this. I'm getting reports back it works mostly. 'ssh site ls' fails, but they can login with Privsep enbled. Can I get those who are using Tru64 or OSF/1 that have SIA enabled to test? This should apple to either -cvs or the current snapshot (I would perfer not to use 3.4p1 due to bugs). I'm going on a trip next week and will be around very spotty

This privsepifies OSF/1 SIA, but I'm still being told the same error occurs. I'm stumped. Without an OSF/1 box near me I can't do too much more help unless someone can either tell me what is wrong or show me why SIA is failing in their logs. (And tell me if it's different w/ or w/out this patch) - Ben Index: auth-sia.c

It still is not right, but thanks to Steve we have gotten this far.. The issue seems to be here: debug3: entering: type 26 debug3: entering debug1: session_new: init debug1: session_new: session 0 debug3: entering: type 26 : sendmsg(12): Invalid argument debug1: Calling cleanup 0x1200365c0(0x14000d9d8) debug1: session_pty_cleanup: session 0 release /dev/ttyp4 debug1: Calling cleanup

The recent patch posted by Steve VanDevender <stevev at darkwing.uoregon.edu> for fixing the session code on Tru64 isn't quite right -- it still fails in the case of NO tty being allocated. The problem is that s->tty is a char[TTYSZ] rather than a char *, and hence can't hold a NULL. Calling sia_ses_init() with the tty being an empty string doesn't signify no tty, and

Okay, here is a fixed version of the patch I sent before for fixing the problems I know about with Digital Unix SIA: displaying too much info (MOTD, last login, etc.) when access is denied, and the loss of the error message sometimes when access is denied. It does break some code out of do_login into a couple of separate functions. I did this to avoid duplicating the code in a couple of places.

Either this never made it to the list or no one cares about Tru64. This is the last time I'll send this patch to the list. If no one steps up and finishes it or provides me with enough information to fix any remaining bugs (one being complaint that 'ssh site cmd' does not work right). If there is no activity on this for a week. I'll post it to bugzilla and will ignore any

Hello. The following is a patch against OpenSSH 3.0.2p1 to fix OpenSSH's handling of Tru64 SIA authentication. The main changes are to make the SIAENTITY a global variable (so that it remains persistent across function calls), initialization only happens once, the session is only released once. This makes SIA modules that require authentication in order to perform certain actions during the

BSD/OS 4.2 comes with OpenSSH 2.1.1p4, patched to support BSDI's authentication library. However, BSDI's patches have several problems: 1. They don't run the approval phase, so they can allow users to login who aren't supposed to be able to. 2. They don't patch configure to automatically detect the BSDI auth system, so they're not ready to use in a general portable

Hi- Under privsep, I experimented with moving the session_setup_sia() out of do_child() and into do_setusercontext(), which is where the uids/gids are set to the final execution user. The call is made with a NULL tty, and this is functional provided that any later pty allocation uses grantpty() to set the device permissions. Logging in with this method shows that a utmp entry does get made for

Hi all, among other things, we provide shell access to various unix based platforms for our students and university staff. Recently, there has been increasing number of root login attacks on one particular Tru64 machine running OpenSSH. The host is configured with "PermitRootLogin no" but every once in a while SIA auth with TCB enhanced security locks the root account. I suppose

The following are patches against openssh 2.1.1p4 to add support for the BSD_AUTH authentication mechanisms. It allows the use of non-challenge/response style mechanisms (which styles are allowed my be limited by appropriate auth-ssh entries in login.conf). The patches also add support for calling setusercontext for the appropriate class when called with a command (so that the PATH, limits,

Hi- Since the tru64 patch was designed for -current, I thought I would try to build it with a recent snapshot before backporting to 3.4p1. So I downloaded openssh-SNAP-20020826.tar.gz frpm the portable snapshots, but it does not contain the 'configure' script. I tried copying the 'configure' from 3.4p1, but that does not create a Makefile from the Makefile.in. Where are the

cvs code from this morning (about 9am PST) breaks on slackware 7.1 w/ gcc 2.95.2.1 with an undefined reference to session_setup_sia in session.o. this seems to be the culprit here: #ifdef HAVE_OSF_SIA #else /* HAVE_OSF_SIA */ session_setup_sia(pw->pw_name, ttyname); since i have no idea what that's trying to accomplish (and seems to be a bit backwards to me from looking

http://bugzilla.mindrot.org/show_bug.cgi?id=445 ------- Additional Comments From simon at sxw.org.uk 2003-05-21 00:49 ------- The existing code only handles the situation where Kerberos credentials are created by the OpenSSH's krb5 code. What would appear to be happening under OSF/1 is that one of the calls used to verify the users login is, as a by-product, creating the credentials

Hello, I'm trying to implement setting of user limits (ulimit) in sshd. I'm not using PAM so I need it in the sshd itself. The task is very simple - just to put one line calling setup_limits(pw); and link with -lshadow. But the problem is, where to put this line. I did it in session.c, in do_child(), like this: #ifdef HAVE_OSF_SIA session_setup_sia(pw, s->ttyfd == -1 ? NULL
