List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: Lustre Development List MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Errors-To: lustre-devel-bounces@lists.lustre.org Sender: "lustre-devel" From: Sebastien Buisson Add a dumb encryption context on OST objects being created, when the LUSTRE_ENCRYPT_FL flag gets set in the LMA, for ldiskfs backend targets. This leads ldiskfs to internally set the LDISKFS_ENCRYPT_FL flag on the on-disk inode. Also, it makes e2fsprogs happy to see an enc ctx for an inode that has the LDISKFS_ENCRYPT_FL flag. Add a dumb encryption context on OST objects being opened, if there is not already one, for ldiskfs backend targets. This is done by adding the LUSTRE_ENCRYPT_FL flag if necessary, at the same time as atime gets updated. It is some sort of live self-check that fixes OST objects created with an older Lustre version.
