Thank you for the responce, but of course I'd tried this before asking. It has no effect. Selinux still prevents to open authorized_keys. I suppose there is something wrong with file contexts at my cephfs. For instance, 'ls -Z' shows just a '?' as a context, and chcon fails with "Operation not supported" message. Where should I look for error?
You can setup a custom SELinux module to enable access. We use the following snippet to allow sshd to access authorized keys in home directories on CephFS:
module local-ceph-ssh-auth 1.0;
require { type cephfs_t; type sshd_t; class file { read getattr open }; }
#============= sshd_t ============== allow sshd_t cephfs_t:file { read getattr open };
Compiling and persistently installing such a module is covered by various documentation, such as: https://wiki.centos.org/HowTos/SELinux#head-aa437f65e1c7873cddbafd9e9a73bbf9... (7.1. Manually Customizing Policy Modules). Also covered there is using audit2allow to create your own module from SELinux audit logs.
thanks, Ben

Hi all,
I would like to have my home dir at cephfs and to keep selinux enabled at the same time.
The trouble is selinux prevents sshd to access ~/.ssh/authorized_keys file. Any ideas how to fix it? _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-leave@ceph.io
