No, SELinux does nothing to NFS over the wire at this stage. You can specify the security context of an NFS mount locally with the context= option to mount. This is something the kernel only sees locally, the remote server is not aware of anything. e.g. # mount -t nfs -o context=system_u:object_r:tmp_t server:/some/path /mnt/wherever All of the files on the mount will appear to have the context system_u:object_r:tmp_t to SELinux.

*** Bug 119719 has been marked as a duplicate of this bug. ***
This is to capture the question from 119719 that is related to this bug; 119719 has been reopened to keep the first question there alive, which is not related to this question. ## begin copy from 119719 Opened by George Moody (george@mit.edu) on 2004-04-01 14:42 Private Comment Here are two questions likely to be frequently asked, missing from the FAQ. They belong right after "Q: I installed Fedora Core on a system with an existing /home partition, and now I can't log in." Q: If I relabel my existing /home partition after upgrading to FC2, will I still be able to read it if I need to revert to FC1? (In other words, am I burning my bridges when I run setfiles or fixfiles?) Q: Can an NFS-mountable /home partition be shared by FC1 and FC2 installations? ------- Additional Comment #1 From Karsten Wade (kwade@redhat.com) on 2004-04-01 17:52 ------- Private Comment Adding blocking (back?) against 118757 for tracking purposes. Research on answers currently occuring on fedora-selinux-list: http://www.redhat.com/archives/fedora-selinux-list/2004-April/msg00012.html ## 30
Here are the revised two questions. Cc:'d are the two developers who have answered these questions on list; please review the accuracy of these comments. I'm going to roll these into the FAQ in the next few hours because I believe they are primarily accurate, and are timely and useful. Please reply to this bug report with any changes. ## begin Q:. After relabeling my /home using setfiles or fixfiles, will I still be able to read the partition with a Fedora Core 1 system? A:. You can read the files from a non-SELinux distribution such as Fedora Core 1 or Red Hat Linux. However, files created by the non-SELinux using systems will not have a security context, nor will any files you remove and recreate. This could be a challenge with files such as ~/.bashrc. You may have to relabel your /home when you return to Fedora Core 2 test2. Q:. How do I share directories using NFS between Fedora Core 2 test2 and non-SELinux systems? A:. Just as NFS transparently supports many file system types, it can be used to share directories between SELinux and non-SELinux systems. When mounting a non-SELinux file system via NFS, by default SELinux will treat all the files in the share as having a context of nfs_t. You can override the default context by setting it manually using the context= option. For example, this would make the files in the NFS mounted directory appear to have a context of system_u:object_r:tmp_t to SELinux: mount -t nfs -o context=system_u:object_r:tmp_t server:/shared/foo /mnt/foo When SELinux exports a file sytem via NFS, files created will have the context of the directory they were created in. In other words, the presence of SELinux on the remote mounting system has no effect on the local file contexts. ## 30
