💖 jabberd_router_selinux — the SELinux glow-up for jabberd_router processes ✨

okay bestie, so this is the jabberd_router_selinux(8) manual page from the SELinux Policy collection, and it's literally all about keeping your jabberd_router processes safe and iconic. no cap, let's get into it 💅

---

🌸 NAME 🌸

jabberd_router_selinux — Security Enhanced Linux Policy for the jabberd_router processes 🫶

---

✨ DESCRIPTION ✨

Security-Enhanced Linux secures the jabberd_router processes via flexible mandatory access control. it's giving strict-but-fair parent energy, fr fr 🔥

The jabberd_router processes execute with the jabberd_router_t SELinux type. you can check if you have these processes running by executing the ps command with the -Z qualifier — that -Z is the main character flag, don't forget it 💀

For example:

ps -eZ | grep jabberd_router_t

---

🚪 ENTRYPOINTS 🚪

The jabberd_router_t SELinux type can be entered via the jabberd_router_exec_t file type. that's the VIP pass into the domain, iykyk 🎀

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

/usr/bin/c2s, /usr/bin/router

---

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system. it's a whole taxonomy situation, obsessed 🌈

You can see the context of a process using the -Z option to ps. yes, -Z again — it's the moment ✨

Policy governs the access confined processes have to files. the SELinux jabberd_router policy is very flexible allowing users to setup their jabberd_router processes in as secure a method as possible. flexible AND secure? we love a multitasking icon 🦋

The following process types are defined for jabberd_router:

jabberd_router_t

Note: semanage permissive -a jabberd_router_t can be used to make the process type jabberd_router_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. so it's like, chill mode but the receipts are still printing 😭

---

🔘 BOOLEANS 🔘

SELinux policy is customizable based on least access required. the jabberd_router policy is extremely flexible and has several booleans that allow you to manipulate the policy and run jabberd_router with the tightest access possible. tightest access = the lewk we're going for 💅

• 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

• 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

periodt, those are your booleans 🫶

📁 MANAGED FILES 📁

The SELinux process type jabberd_router_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 — SELinux isn't doing ALL the work, bestie 😌

• cluster_conf_t

/etc/cluster(/.*)?

• cluster_var_lib_t

/var/lib/pcsd(/.*)?
/var/lib/cluster(/.*)?
/var/lib/openais(/.*)?
/var/lib/pengine(/.*)?
/var/lib/corosync(/.*)?
/usr/lib/heartbeat(/.*)?
/var/lib/heartbeat(/.*)?
/var/lib/pacemaker(/.*)?

• cluster_var_run_t

/run/crm(/.*)?
/run/cman_.*
/run/rsctmp(/.*)?
/run/aisexec.*
/run/heartbeat(/.*)?
/run/pcsd-ruby.socket
/run/corosync-qnetd(/.*)?
/run/corosync-qdevice(/.*)?
/run/pcsd.socket
/run/corosync.pid
/run/cpglockd.pid
/run/rgmanager.pid
/run/cluster/rgmanager.sk

• jabberd_var_lib_t

/var/lib/jabberd(/.*)?

• root_t

/sysroot/.aleph-version.json
/sysroot/ostree/deploy/.*-atomic/deploy(/.*)?
/
/initrd
/var/lib/ntp

🏷️ FILE CONTEXTS 🏷️

SELinux requires files to have an extended attribute to define the file type. it's literally the file's whole identity, no cap 💖

You can see the context of a file using the -Z option to ls — yes, -Z stays booked and busy 🔥

Policy governs the access confined processes have to these files. the SELinux jabberd_router policy is very flexible allowing users to setup their jabberd_router processes in as secure a method as possible. again with the flexible + secure combo, we stan 😭

💫 STANDARD FILE CONTEXT 💫

SELinux defines the file context types for the jabberd_router, 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. relabeling glow-up, let's go ✨

semanage fcontext -a -t jabberd_router_exec_t '/srv/jabberd_router/content(/.*)?'
restorecon -R -v /srv/myjabberd_router_content

Note: SELinux often uses regular expressions to specify labels that match multiple files. regex girlies rise 🧚

The following file types are defined for jabberd_router:

• jabberd_router_exec_t — Set files with the jabberd_router_exec_t type, if you want to transition an executable to the jabberd_router_t domain.

Paths:

/usr/bin/c2s, /usr/bin/router

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. temporary vs permanent — choose wisely bestie 💀

---

🧰 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. GUI for the visual girlies 🎀
