spamc_selinux(8) SELinux Policy spamc spamc_selinux(8)
NAME
spamc_selinux - Security Enhanced Linux Policy for the spamc processes
DESCRIPTION
Security-Enhanced Linux secures the spamc processes via flexible mandatory access control.
The spamc processes execute with the spamc_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 spamc_t
ENTRYPOINTS
The spamc_t SELinux type can be entered via the spamc_exec_t file type.
The default entrypoint paths for the spamc_t domain are the following:
/usr/bin/razor.*, /usr/bin/spamc, /usr/bin/pyzor, /usr/bin/sa-learn, /usr/bin/spamassassin
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 spamc policy is very flexible allowing users to setup their spamc pro-
cesses in as secure a method as possible.
The following process types are defined for spamc:
spamc_t
Note: semanage permissive -a spamc_t can be used to make the process type spamc_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. spamc policy is extremely flexible and has several booleans that allow you
to manipulate the policy and run spamc with the tightest access possible.
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.

default.

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 http daemon to check spam, you must turn on the httpd_can_check_spam boolean. Disabled by default.

setsebool -P nis_enabled 1

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 spamc_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 spamc_t, you must turn on the kerberos_enabled boolean.
setsebool -P kerberos_enabled 1
MANAGED FILES
The SELinux process type spamc_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 spamc policy is very flexible allowing users to setup their
spamc processes in as secure a method as possible.
STANDARD FILE CONTEXT
SELinux defines the file context types for the spamc, 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 spamc_exec_t '/srv/spamc/content(/.*)?'
restorecon -R -v /srv/myspamc_content
Note: SELinux often uses regular expressions to specify labels that match multiple files.
The following file types are defined for spamc:
spamc_exec_t
- Set files with the spamc_exec_t type, if you want to transition an executable to the spamc_t domain.
Paths:
/usr/bin/razor.*, /usr/bin/spamc, /usr/bin/pyzor, /usr/bin/sa-learn, /usr/bin/spamassassin
spamc_home_t
- Set files with the spamc_home_t type, if you want to store spamc files in the users home directory.
Paths:
/root/.pyzor(/.*)?, /root/.razor(/.*)?, /root/.spamd(/.*)?, /root/.spamassassin(/.*)?, /home/[^/]*/.pyzor(/.*)?,
/home/[^/]*/.razor(/.*)?, /home/[^/]*/.spamd(/.*)?, /home/[^/]*/.spamassassin(/.*)?
spamc_tmp_t
- Set files with the spamc_tmp_t type, if you want to store spamc temporary files in the /tmp directories.
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.
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.
