From e9554f7792d893f0ea8afe368829f9944ef52bdf Mon Sep 17 00:00:00 2001 From: Santosh Kumar Pradhan Date: Thu, 19 Sep 2013 12:01:38 +0530 Subject: gNFS: Incorrect NFS ACL encoding for XFS Problem: Incorrect NFS ACL encoding causes "system.posix_acl_default" setxattr failure on bricks on XFS file system. XFS (potentially others?) doesn't understand when the 0x10 prefix is added to the ACL type field for default ACLs (which the Linux NFS client adds) which causes setfacl()->setxattr() to fail silently. NFS client adds NFS_ACL_DEFAULT(0x1000) for default ACL. FIX: Mask the prefix (added by NFS client) OFF, so the setfacl is not rejected when it hits the FS.
