raise glibc requirements

You need to
before you can comment on or make changes to this bug.
At some point we should consider raising our requirements on glibc so that we
can make use of newer features.
For the server this is probably not a big issue as our requirements on other
things forces a new glibc anyway.
The big problem is the terminals which might be based on ancient distributions.
I did an inventory and raising the requirement to 2.11.3 will still handle all
interesting terminals. This unfortunately doesn't get us the memcpy()
performance improvement (2.14), but it does mean we can have the same glibc for
all our build environments. It will probably also solve various minor
For reference, it is Wyse SUSE Linux 11 that has the oldest glibc. However RHEL
6 has 2.12 so we couldn't go much further even without Wyse. Third oldest is
RHEL 7 with 2.17.
The old Wyse SUSE Linux 11 is on its way out anyway as we'll start looking at
it's replacement soon (bug 6199). Dell still claims these devices aren't EOL,
but they haven't been sold in years.
Let's not let these devices hold us back and we'll use RHEL 6 as a base for
The upstream SLES 11 is also affected by this. Support for it ends in March
2019. That is not long after our next release is out, so it's not really a
problem dropping support for it.
Should be all done. I cannot find any more references to wyse or glibc that
I also tested the autotest by putting some Fedora binaries in
I verified the code changes and couldn't find any more places that mention
glibc or wyse that needs to be updated. The documentation and release notes
looks good as well.
