- ZFS will now reject read(2) of a dirfd with EISDIR.
+r361238, r361798, r361799:
+ ZFS will now unconditionally reject read(2) of a directory with EISDIR.
+ Additionally, read(2) of a directory is now rejected with EISDIR by
+ default and may be re-enabled for non-ZFS filesystems that allow it with
+ the sysctl(8) MIB 'security.bsd.allow_read_dir'.
+ Aliases for grep to default to '-d skip' may be desired if commonly
+ non-recursively grepping a list that includes directories and the
+ possibility of EISDIR errors in stderr is not tolerable. Example
+ aliases, commented out, have been installed in /root/.cshrc and
+ /root/.shrc.
Add exec.prepare and exec.release hooks for jail(8) and jail.conf(5).
