innd_selinux(8)

🎀 NAME 🎀

innd_selinux(8) — Security Enhanced Linux Policy for the innd processes. Bestie, this is the manual-name moment: innd_selinux is the SELinux policy page for innd, and we are about to unfold it like a very useful group chat. 💅

🦋 DESCRIPTION 🦋

Security-Enhanced Linux secures the innd processes via flexible mandatory access control. No cap, that is the whole security vibe.

The innd processes execute with the innd_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 innd_t

✨ ENTRYPOINTS ✨

The innd_t SELinux type can be entered via the innd_exec_t file type.

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

/usr/bin/innd.*, /usr/libexec/news/rc.news, /usr/bin/suck,
/etc/news/boot, /usr/bin/inews, /usr/bin/rnews, /usr/bin/rpost,

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

The following process types are defined for innd:

• innd_t

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

• daemons_dontaudit_scheduling — if you want to dontaudit all daemons scheduling requests (setsched, sys_nice), you must turn on the daemons_dontaudit_scheduling boolean. Enabled by default. setsebool -P daemons_dontaudit_scheduling 1
• fips_mode — 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
• nis_enabled — 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

🌈 PORT TYPES 🌈

SELinux defines port types to represent TCP and UDP ports.

You can see the types associated with a port by using the following command:

semanage port -l

Policy governs the access confined processes have to these ports. SELinux innd policy is very flexible allowing users to setup their innd processes in as secure a method as possible.

The following port types are defined for innd:

• innd_port_t

Default Defined Ports:

tcp 119

💾 MANAGED FILES 💾

The SELinux process type innd_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 innd policy is very flexible allowing users to setup their innd processes in as secure a method as possible.

💖 STANDARD FILE CONTEXT 💖

SELinux defines the file context types for the innd, if you wanted to store files with these types in a different paths, you need to execute the semanage command to specify alternate labeling and then use restorecon to put the labels on disk.

semanage fcontext -a -t innd_exec_t '/srv/innd/content(/.*)?'
restorecon -R -v /srv/myinnd_content

Note: SELinux often uses regular expressions to specify labels that match multiple files.

The following file types are defined for innd:

🫶 innd_etc_t 🫶

• Set files with the innd_etc_t type, if you want to store innd files in the /etc directories.

🫶 innd_exec_t 🫶

• Set files with the innd_exec_t type, if you want to transition an executable to the innd_t domain.

Paths:

/usr/bin/innd.*, /usr/libexec/news/rc.news, /usr/bin/suck,
/etc/news/boot, /usr/bin/inews, /usr/bin/rnews, /usr/bin/rpost,
/usr/bin/in.nnrpd, /usr/libexec/news/sm, /usr/libexec/news/innd,

/usr/libexec/news/prunehistory, /usr/libexec/news/startinnfeed

🫶 innd_initrc_exec_t 🫶

• Set files with the innd_initrc_exec_t type, if you want to transition an executable to the innd_initrc_t domain.

🫶 innd_log_t 🫶

• Set files with the innd_log_t type, if you want to treat the data as innd log data, usually stored under the /var/log directory.

🫶 innd_unit_file_t 🫶

• Set files with the innd_unit_file_t type, if you want to treat the files as innd unit content.

🫶 innd_var_lib_t 🫶

• Set files with the innd_var_lib_t type, if you want to store the innd files under the /var/lib directory.

🫶 innd_var_run_t 🫶

• Set files with the innd_var_run_t type, if you want to store the innd files under the /run or /var/run directory.

Paths:

/run/innd(/.*)?, /run/news(/.*)?, /run/innd.pid, /run/news.pid

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 port can also be used to manipulate the port definitions
• semanage boolean can also be used to manipulate the booleans
• system-config-selinux is a GUI tool available to customize SELinux policy settings.
