Properly evaluate edge cases where user credential may grant capability to override DAC in various situations. Switch to using ns-aware checks rather than capable(). Expand optimization allow bypass of zfs_zaccess() in case of trivial ACL if MAY_OPEN is included in requested mask. This will be evaluated in generic_permission() check, which is RCU walk safe. This means that in most cases evaluating permissions on boot volume with NFSv4 ACLs will follow the fast path on checking inode permissions. Additionally, CAP_SYS_ADMIN is granted to nfsd process, and so override for this capability in access2 policy check is removed in favor of a simple check for fsid == 0. Checks for CAP_DAC_OVERRIDE and other override capabilities are kept as-is. Signed-off-by: Andrew Walker <awalker@ixsystems.com> |
