Description Mikhail 2023-04-25 07:05:28 UTC
Description of problem:
SELinux is preventing systemd from 'map' accesses on the file /etc/selinux/targeted/policy/policy.33.

*****  Plugin catchall_boolean (89.3 confidence) suggests   ******************

If you want to allow domain to can mmap files
Then you must tell SELinux about this by enabling the 'domain_can_mmap_files' boolean.

Do
setsebool -P domain_can_mmap_files 1

*****  Plugin catchall (11.6 confidence) suggests   **************************

If you believe that systemd should be allowed map access on the policy.33 file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'systemd' --raw | audit2allow -M my-systemd
# semodule -X 300 -i my-systemd.pp

Comment 3 Zdenek Pytela 2023-04-28 15:09:31 UTC
As discussed with Michal today, this is a result of a change in systemd:

f36# ps w 1
    PID TTY      STAT   TIME COMMAND
      1 ?        Ss     0:09 /usr/lib/systemd/systemd --switched-root --system --deserialize 31
f38# ps w 1
    PID TTY      STAT   TIME COMMAND
      1 ?        Ss     0:27 /usr/lib/systemd/systemd --system --deserialize=45

which requires a code change not to use streq() for "deserialize" which has already been accepted upstream so should appear in rawhide soon and backported to F38.
