The NEWS update should include a pointer to this page or something like
it, so that users can get an understanding of what application updates are
needed (and what already exist) to use alternative interfaces for the
database of user login sessions.
Hi, I want to come back to this patch. I haven't seen any feedback or actions anymore after Josephs comment, that the link to my blog should be added to the news section. At SUSE/openSUSE all new products don't have /run/utmp nor /var/log/wtmp anymore. But applications checking return code of the utmp/wtmp functions report an error, if this files don't exist. So it would be really nice if we could make this functions a NOP at compile time. Thanks, Thorsten On Thu, Nov 09, Adhemerval Zanella <adhemerval.zanella@linaro.org> wrote: > > The user accounting database functions are now deprecated and do not > access or update the database files.

For example, does GNU coreutils 9.5 work correctly without SUSE needing to patch it? I'm asking because Gnulib attempts to work around the problems with glibc and those files being removed.

I haven't seen any problems with Gnulib based programs, coreutils has no open issues and I don't see any patches in this area. sshd is for example an application which creates a lot of messages around utmp/wtmp.

On 2.40 we changed the way utmp/utmpx to handle the seconds-since-epoch types as unsigned 32-bit type (commit 5361ad3910c257bc327567be76fde532ed238e42); so at least it is not a y2038 issue anymore. It still does not solve other bad designs from the API and/or implementation (like BZ #24492); but this also does not seem to be an urgent issue for other distros like Fedora.

How should that solve the Y2038 issue? I'm not aware of any application which interprets the int32 time value as unsigned value. And since this interpretation is done in the application and not inside glibc, you need to touch every single line of code handling utmp entries. With how many projects did you already spoke that they adjust their code? And how do applications find out, if the value was written as int or as uint? For me this is not a solution for the Y2038, that issue still exists.

It is not and it is explicit stated in the NEWS entry: * Architectures which use a 32-bit seconds-since-epoch field in struct lastlog, struct utmp, struct utmpx (such as i386, powerpc64le, rv32, rv64, x86-64) switched from a signed to an unsigned type for that field. This allows these fields to store timestamps beyond the year 2038, until the year 2106. Please note that applications are still expected to migrate off the interfaces declared in <utmp.h> and <utmpx.h> (except for login_tty) due to locking and session management problems. And the patch make is explicit that the intent is to give distributions more time to switch to improved interfaces that also avoid locking/data corruption issues. The long-term solution is still moving away from current implementation.

It does move the goalposts from 2038 to 2106. I agree that it's not ideal, and that we should instead fix the API.

I think to really fixing the API would require to move the utmp/utmpx handling out of the process, otherwise we will need quite complex solution to proper BZ#24492. And these issues exist for a long time, without much traction to fix on glibc. The unsigned trick is a rubber band, but the implementation is still clunky in some parts. That's why I still think best course of action is just to deprecate this API on glibc side and move to what Thorsten has suggested some years ago.
