logrotate_selinux — Security Enhanced Linux Policy for the logrotate processes
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 command with the -Z qualifier.
ps -eZ | grep logrotate_t
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 following:
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 psbP
Policy governs the access confined processes have to files. SELinux logrotate policy is very flexible allowing users to setup their logrotate processes in as secure a method as possible.
The following process types are defined for logrotate:
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.
SELinux policy is customizable based on least access required. logrotate 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 read logs inside, you must turn on the logrotate_read_inside_containers boolean. Disabled by default.
setsebool -P logrotate_read_inside_containers 1
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 authlogin_nsswitch_use_ldap boolean. Disabled by default.
setsebool -P authlogin_nsswitch_use_ldap 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 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
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.
all log files
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 lsbP
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.
logrotate policy stores data with multiple different file context types under the /var/lib/logrotate directory. If you would like to store the data in a different directory you can use the semanage command to create an equivalence mapping. If you wanted to store this data under the /srv dirctory you would execute the following command:
semanage fcontext -a -e /var/lib/logrotate /srv/logrotate
restorecon -R -v /srv/logrotate
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_mail_tmp_t '/srv/mylogrotate_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:
- Set files with the logrotate_exec_t type, if you want to transition an executable to the logrotate_t domain.
- 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
- Set files with the logrotate_mail_tmp_t type, if you want to store logrotate mail temporary files in the /tmp directories.
- Set files with the logrotate_tmp_t type, if you want to store logrotate temporary files in the /tmp directories.
- 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 database. You will need to use restorecon to apply the labels.
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 policy modules.
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux policy settings.
