logrotate_selinux(8) SELinux Policy logrotate logrotate_selinux(8)NAMElogrotate_selinux - Security Enhanced Linux Policy for the logrotate
processes
DESCRIPTION
Security-Enhanced Linux secures the logrotate processes via flexible
mandatory access control.
The logrotate processes execute with the logrotate_t SELinux type. You
can check if you have these processes running by executing the ps com‐
mand with the -Z qualifier.
For example:
ps -eZ | grep logrotate_t
ENTRYPOINTS
The logrotate_t SELinux type can be entered via the logrotate_exec_t
file type.
The default entrypoint paths for the logrotate_t domain are the follow‐
ing:
/etc/cron.(daily|weekly)/sysklogd, /usr/sbin/logrotate
PROCESS TYPES
SELinux defines process types (domains) for each process running on the
system
You can see the context of a process using the -Z option to ps
Policy governs the access confined processes have to files. SELinux
logrotate policy is very flexible allowing users to setup their logro‐
tate processes in as secure a method as possible.
The following process types are defined for logrotate:
logrotate_t, logrotate_mail_t
Note: semanage permissive -a logrotate_t can be used to make the
process type logrotate_t permissive. SELinux does not deny access to
permissive process types, but the AVC (SELinux denials) messages are
still generated.
BOOLEANS
SELinux policy is customizable based on least access required. logro‐
tate policy is extremely flexible and has several booleans that allow
you to manipulate the policy and run logrotate with the tightest access
possible.
If you want to allow logrotate to manage nfs files, you must turn on
the logrotate_use_nfs boolean. Disabled by default.
setsebool -P logrotate_use_nfs 1
If you want to allow users to resolve user passwd entries directly from
ldap rather then using a sssd server, you must turn on the authlo‐
gin_nsswitch_use_ldap boolean. Disabled by default.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to deny any process from ptracing or debugging any other
processes, you must turn on the deny_ptrace boolean. Enabled by
default.
setsebool -P deny_ptrace 1
If you want to allow all domains to use other domains file descriptors,
you must turn on the domain_fd_use boolean. Enabled by default.
setsebool -P domain_fd_use 1
If you want to allow all domains to have the kernel load modules, you
must turn on the domain_kernel_load_modules boolean. Disabled by
default.
setsebool -P domain_kernel_load_modules 1
If you want to allow all domains to execute in fips_mode, you must turn
on the fips_mode boolean. Enabled by default.
setsebool -P fips_mode 1
If you want to enable reading of urandom for all domains, you must turn
on the global_ssp boolean. Disabled by default.
setsebool -P global_ssp 1
If you want to allow confined applications to run with kerberos, you
must turn on the kerberos_enabled boolean. Enabled by default.
setsebool -P kerberos_enabled 1
If you want to allow system to run with NIS, you must turn on the
nis_enabled boolean. Disabled by default.
setsebool -P nis_enabled 1
If you want to allow confined applications to use nscd shared memory,
you must turn on the nscd_use_shm boolean. Disabled by default.
setsebool -P nscd_use_shm 1
If you want to support NFS home directories, you must turn on the
use_nfs_home_dirs boolean. Disabled by default.
setsebool -P use_nfs_home_dirs 1
If you want to support SAMBA home directories, you must turn on the
use_samba_home_dirs boolean. Disabled by default.
setsebool -P use_samba_home_dirs 1
NSSWITCH DOMAIN
If you want to allow users to resolve user passwd entries directly from
ldap rather then using a sssd server for the logrotate_t, logro‐
tate_mail_t, you must turn on the authlogin_nsswitch_use_ldap boolean.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow confined applications to run with kerberos for the
logrotate_t, logrotate_mail_t, you must turn on the kerberos_enabled
boolean.
setsebool -P kerberos_enabled 1
MANAGED FILES
The SELinux process type logrotate_t can manage files labeled with the
following file types. The paths listed are the default paths for these
file types. Note the processes UID still need to have DAC permissions.

FILE CONTEXTS
SELinux requires files to have an extended attribute to define the file
type.
You can see the context of a file using the -Z option to ls
Policy governs the access confined processes have to these files.
SELinux logrotate policy is very flexible allowing users to setup their
logrotate processes in as secure a method as possible.
STANDARD FILE CONTEXT
SELinux defines the file context types for the logrotate, if you wanted
to store files with these types in a diffent paths, you need to execute
the semanage command to sepecify alternate labeling and then use
restorecon to put the labels on disk.
semanage fcontext -a -t logrotate_exec_t '/srv/logrotate/content(/.*)?'
restorecon -R -v /srv/mylogrotate_content
Note: SELinux often uses regular expressions to specify labels that
match multiple files.
The following file types are defined for logrotate:
logrotate_exec_t
- Set files with the logrotate_exec_t type, if you want to transition
an executable to the logrotate_t domain.
Paths:
/etc/cron.(daily|weekly)/sysklogd, /usr/sbin/logrotate
logrotate_lock_t
- Set files with the logrotate_lock_t type, if you want to treat the
files as logrotate lock data, stored under the /var/lock directory
logrotate_mail_tmp_t
- Set files with the logrotate_mail_tmp_t type, if you want to store
logrotate mail temporary files in the /tmp directories.
logrotate_tmp_t
- Set files with the logrotate_tmp_t type, if you want to store logro‐
tate temporary files in the /tmp directories.
logrotate_var_lib_t
- Set files with the logrotate_var_lib_t type, if you want to store the
logrotate files under the /var/lib directory.
Note: File context can be temporarily modified with the chcon command.
If you want to permanently change the file context you need to use the
semanage fcontext command. This will modify the SELinux labeling data‐
base. You will need to use restorecon to apply the labels.
COMMANDS
semanage fcontext can also be used to manipulate default file context
mappings.
semanage permissive can also be used to manipulate whether or not a
process type is permissive.
semanage module can also be used to enable/disable/install/remove pol‐
icy modules.
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux pol‐
icy settings.
