Hi,
In the nfsd_selinux man page it mentions:
nfsd_ro_t nfsd_rw_t
...which might give you the impression that those are the labels you might
use for your shares. I tried them and the client could mount the shares
read-write (regardless of the label on the server). Clearly they don't work
or perhaps I'm using them in an unintended way.
After searching the mailing list I found out that, since nfs mainly runs as
a kernel module, SELinux can't control it. Apparently that's also the
reason the read-only and read-write booleans were removed. I'm now
wondering:
Did NFS used to run as a daemon in the past?
Since NFS is practically unconfined, what are the nfsd_ro_t and rw_t
labels for?
Thanks!
They should be removed, they are not used and make no sense since nfs is built
into the kernel. I believe the idea years ago was to allow an admin to
specify which files could be shared via NFS read only and which could be
shared read/write.
