| revalidate data present in inode entries for chown | |

Description: sys_stat() does a do_revalidate() after user_path_walk() but sys_chown() does not. This causes sys_chown() to use incorrect attribute information on distributed file systems. The sys_stat does do_revalidate() to revalidate the inodes for proper NFS attibute caching. But when sys_chown calls chown_common after the user_path_walk, no checks are being done regarding the dentry values, which contain cached inode values. On Distributed File system environments there may be a likelyhood that these values may not be current and there is a likelihood of stale values being read. Hence doing a do_revalidate before the chown calls will help address this issue. |
