Dirent events (create/delete/move) are only reported on watched directory inodes, but in fanotify as well as in legacy inotify, it was always allowed to set them on non-dir inode, which does not result in any meaningful outcome. Until kernel v5.17, dirent events in fanotify also differed from events "on child" (e.g. FAN_OPEN) in the information provided in the event. For example, FAN_OPEN could be set in the mask of a non-dir or the mask of its parent and event would report the fid of the child regardless of the marked object. By contrast, FAN_DELETE is not reported if the child is marked and the child fid was not reported in the events. Since kernel v5.17, with fanotify group flag FAN_REPORT_TARGET_FID, the fid of the child is reported with dirent events, like events "on child", which may create confusion for users expecting the same behavior as events "on child" when setting events in the mask on a child. The desired semantics of setting dirent events in the mask of a child are not clear, so for now, deny this action for a group initialized with flag FAN_REPORT_TARGET_FID and for the new event FAN_RENAME. We may relax this restriction in the future if we decide on the semantics and implement them. Fixes: |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
