Passthrough X Deferred Update - Oracle ZFS Storage Appliance Service Manual

Passthrough x Deferred Update

both 2011.1.4.2 and 2013.1 but the 2013.1 update is unavailable because you first need to
upgrade to at least 2011.1.4.2.
Deferred updates:
The following incompatible updates are available. Applying these updates will
enable new software features as described below, but will prevent older
versions of the software from accessing the underlying resources. You should
apply deferred updates once you have verified that the current software update
is functioning and a rollback is not required. Applying deferred updates in a
cluster will also update any resources on the cluster peer.
1. Support for the "passthrough-x" aclinherit property for shares.

Passthrough x Deferred Update
For filesystems, ACLs are inherited according to the "aclinherit" property on the filesystem (or
inherited from the project). Previous versions of software allowed four options for this setting:
"discard", "noallow", "restricted", and "passthrough". The 2009.Q2.0.0 release introduces
a new option, "passthrough-x", with slightly different semantics as described in the product
documentation:
Same as "passthrough", except that the owner, group, and everyone ACL entries inherit the
execute permission only if the file creation mode also requests the execute bit.
The "passthrough" mode is typically used to cause all "data" files to be created with an identical
mode in a directory tree. An administrator sets up ACL inheritance so that all files are created
with a mode, such as 0664 or 0666. This all works as expected for data files, but you might
want to optionally include the execute bit from the file creation mode into the inherited ACL.
One example is an output file that is generated from tools, such as "cc" or "gcc". If the inherited
ACL does not include the execute bit, then the output executable from the compiler is not
executable until you use chmod(1) to change the permissions for the file.
