Doc Type: Bug Fix
Doc Text:
.Improvements to the encoding and decoding of messages on storage clusters When deploying a {storage-product} cluster containing a heterogeneous architecture, such as x86_64 and s390, could cause system crashes. Also, under certain workloads for CephFS, Ceph Monitors on s390x nodes could crash unexpectedly. With this release, properly decoding `entity_addrvec_t` with a marker of `1`, properly decoding the `enum` types on big-endian systems by using an intermediate integer variable type, and fixed encoding and decoding `float` types on big-endian systems. As a result, heterogeneous storage clusters, and Ceph Monitors on s390x nodes no longer crash.

Comment 2 Christina Meno 2020-11-10 22:10:27 UTC 
To git.redhat.com:ceph/ceph.git
   d3de268..2e68222  ceph-4.1-rhel-patches -> ceph-4.1-rhel-patches

I checked the PRs and this appears to contain all the required code.
Eduard please double check me when you're back from PTO

Yes, all 3 patches are backported. Looks good for me.
