Description eric gerbier 2017-08-11 11:30:12 CEST 
Description of problem:
On mageia 6 (and 5), try to use fanotify api to monitor files events.
I first try with the c code example from man 7 fanotify
but the program always exit with the errno message : fanotify_mark: Invalid argument.
the same code works without any problem on other recent linux distributions : fedora 26, ubuntu 17.04

 
Version-Release number of selected component (if applicable):
tested with kernel 4.9.90-desktop-1, 4.9.35-server-1

How reproducible:
every time 

Steps to Reproduce:
1. take the c code example from man 7 fanotify : test_fanotify.c 
2. compile it with : gcc -o test_fanotify test_fanotify.c
3. run it under root : sudo ./test_fanotify  /tmp

Comment 2 eric gerbier 2017-09-12 16:36:13 CEST 
The test code does not work because CONFIG_FANOTIFY_ACCESS_PERMISSIONS is not set
in the kernel.

$ grep FANOTIFY /boot/config-4.9.35-server-1.mga6 
CONFIG_FANOTIFY=y
# CONFIG_FANOTIFY_ACCESS_PERMISSIONS is not set
