Summary: sshd dies by non-root account session
Product: Portable OpenSSH
Version: 3.7.1p1
Platform: MIPS
OS/Version: IRIX
Status: NEW
Severity: normal
Priority: P3
Component: sshd
AssignedTo: openssh-bugs@mindrot.org
ReportedBy: yuki@sse.co.jp
CC: yuki@sse.co.jp

A sshd built by IRIX v6.5.19m with c99 (MIPSPro v7.4) dies when non-root
user account establishes a session with openssh client. This does not
occurs when root establishes a session.

I found a problem in uidswap.c, and made a patch to fix this problem.

Created an attachment (id=430)
--> (http://bugzilla.mindrot.org/attachment.cgi?id=430&action=view)
patch for sshd v3.7.1p1 under IRIX Audit environment

Apply this patch as follows;

% gzcat openssh-3.7.1p1.tar.gz | tar xf -
% cd openssh-3.7.1p1
% patch < somewhere/patch.withIRIXAudit

Maybe some code cleaning up would be required, but this can correct
the problem temporally.

Do the #defines in bug #659 solve it without this patch?

I could fix my problem without appling the patch for bug #659.
(Sorry, I didnot refer bug #659 report during fixing this problem.)

I found sshd's UID is changed by setsatid() in openbsd-compat/port-irix.c,
the stored old UID must be changed by setsatid() again.

So, my answer is "Yes, but I know nothing about bug #659".

Please try tomorrow's snapshot. The patch from bug #659 has been applied, so if
the snapshot works as-is, please close the bug.
