Using Vagrant with fedora/28-cloud-base image, SELinux logins are
configured this way:
# semanage login -l
Login Name SELinux User MLS/MCS Range Service
__default__ unconfined_u s0-s0:c0.c1023 *
root unconfined_u s0-s0:c0.c1023 *
vagrant unconfined_u s0-s0:c0.c1023 *
Using "chcat -l +c42 vagrant" successfully adds the category to user
vagrant, but "chcat -l -- -c42 vagrant" fails to remove it.
semanage login -l returns:
vagrant unconfined_u s0-s0:c0.c1023,c42 *
This issue is caused by expandCats(), which refuses to return a list of
more than 25 categories. This causes chcat_user_remove() to work with
cats=['c0.c1023,c42'] instead of cats=['c0.c102','c42'], which leads to
it not been able to remove 'c42' from the list.
Fix this issue by splitting the list of categories before calling
expandCats().
