Description

This issue was created by maloo for S Buisson <[e-mail]>

This issue relates to the following test suite run: https://testing.whamcloud.com/test_sets/759a0bee-28af-4ea7-8e73-4d6253abbf7c

test_5 failed with the following error:

sec context seen from 1st mount point is not correct

In fact, the way the test retrieves SELinux security context is broken.
On CentOS 7, output of ls -lZ is made of 5 fields, and sec context is the 4th one, like in this example:

-rw-r--r--. root root unconfined_u:object_r:user_tmp_t:s0 /tmp/sanity-selinux.log

However, on CentOS 8, output of ls -lZ is made of 10 fields, and sec context is the 5th one:

-rw-r--r--. 1 root root unconfined_u:object_r:nfs_t:s0 0 May 16 03:36 /mnt/lustre/df5

Not only test_5 is impacted, but also test_10 and test_20a.
