1. Feature Overview:
Feature Id: 
a. Name of Feature: Provide a utmp format that is compatible between 32 and 64 bit.
b. Feature Description
The utmp definition for the 64 bit version of the C-runtime on Linux for System z needs to be the
same as the utmp definition for the 32 bit version. That way 32 bit applications running in the 64
bit compatability layer can access the records. This change breaks a number of interfaces in the 64
bit C-runtime . which need to be versioned and a compat function for old executables using the 64
bit version of the struct utmp is required. The list of affected interfaces include: login,
updwtmp, getutent, getutid, getutline, pututline, getutent_r, getutid_r, getutline_r, getutxent,
getutxid, getutxline, pututxline, updwtmpx, getutmp, getutmpx. and some more which have not been
2. Feature Details:
Arch Specificity: Purely Arch Specific Code
Affects Toolchain: Yes
Delivery Mechanism: Direct from community
Request Type: Toolchain - Enhancement from IBM
d. Upstream Acceptance: Accepted
Sponsor Priority 1
f. Severity: High
IBM Confidential: no
Code Contribution: IBM code
g. Component Version Target: glibc 2.9
3. Business Case
The 32/64 bit compatible utmp format is a requirement for the LSB 4.0 certification.

Has this work been submitted upstream yet?
Switching Severity from Urgent to High. Urgent should be reserved for problems that need to be fixed asynch.
(In reply to comment #4)
> Has this work been submitted upstream yet?
Yes, this is in glibc upstream.
OK - setting to MODIFIED.
The feature requested has already been accepted into the upstream code base
planned for the next major release of Red Hat Enterprise Linux.
When the next milestone release of Red Hat Enterprise Linux 6 is available,
please verify that the feature requested is present and functioning as
Fixed in 'glibc-2.10.90-26', included in compose 'RHEL6.0-20091028.0'.
Moving to ON_QA.

This is verified included in RHEL6 with upstream glibc 2.10
Set feature request to verified. Thx
Red Hat Enterprise Linux 6.0 is now available and should resolve
the problem described in this bug report. This report is therefore being closed
with a resolution of CURRENTRELEASE. You may reopen this bug report if the
solution does not work for you.
