NAME¶

logrotate_mail_selinux - Security Enhanced Linux Policy for the logrotate_mail processes

DESCRIPTION¶

Security-Enhanced Linux secures the logrotate_mail processes via flexible mandatory access control.

The logrotate_mail processes execute with the logrotate_mail_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.

For example:

ps -eZ | grep logrotate_mail_t

ENTRYPOINTS¶

The logrotate_mail_t SELinux type can be entered via the mta_exec_type, sendmail_exec_t file types.

The default entrypoint paths for the logrotate_mail_t domain are the following:

/usr/lib(64)?/sendmail, /bin/mail(x)?, /usr/sbin/sendmail(.sendmail)?, /usr/bin/esmtp, /usr/sbin/ssmtp, /usr/sbin/rmail, /var/qmail/bin/sendmail, /usr/sbin/sendmail.postfix

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_mail policy is very flexible allowing users to setup their logrotate_mail processes in as secure a method as possible.

The following process types are defined for logrotate_mail:

logrotate_mail_t

Note: semanage permissive -a logrotate_mail_t can be used to make the process type logrotate_mail_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. logrotate_mail policy is extremely flexible and has several booleans that allow you to manipulate the policy and run logrotate_mail with the tightest access possible.

If you want to allow all domains to use other domains file descriptors, you must turn on the allow_domain_fd_use boolean. Enabled by default.

setsebool -P allow_domain_fd_use 1

If you want to allow confined applications to run with kerberos, you must turn on the allow_kerberos boolean. Enabled by default.

setsebool -P allow_kerberos 1

If you want to allow sysadm to debug or ptrace all processes, you must turn on the allow_ptrace boolean. Disabled by default.

setsebool -P allow_ptrace 1

If you want to allow system to run with NIS, you must turn on the allow_ypbind boolean. Disabled by default.

setsebool -P allow_ypbind 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 use nscd shared memory, you must turn on the nscd_use_shm boolean. Enabled by default.

setsebool -P nscd_use_shm 1

MANAGED FILES¶

The SELinux process type logrotate_mail_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.

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 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.
