💅 srvsvcd_selinux(8) — the girl's guide to the SELinux policy for srvsvcd

okay so bestie, buckle up, this is the manual page for srvsvcd_selinux from section 8 of the manual, and it's literally all about how SELinux keeps the srvsvcd processes on a leash 💖

---

🌸 NAME 🌸

srvsvcd_selinux — the Security Enhanced Linux Policy for the srvsvcd processes. she's the vibe check for those daemons, no cap ✨

---

🦋 DESCRIPTION 🦋

Security-Enhanced Linux secures the srvsvcd processes via flexible mandatory access control. it's giving "we love a boundaries queen" 💅

The srvsvcd processes execute with the srvsvcd_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 srvsvcd_t

see? iconic. 🎀

---

🧚 ENTRYPOINTS 🧚

The srvsvcd_t SELinux type can be entered via the srvsvcd_exec_t file type.

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

/usr/bin/srvsvcd, /opt/likewise/sbin/srvsvcd

those two are the doors into the domain, bestie 🚪✨

---

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

The following process types are defined for srvsvcd:

srvsvcd_t

Note: semanage permissive -a srvsvcd_t can be used to make the process type srvsvcd_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. so like, she stops yelling at you but she's still journaling about it in the AVCs 😭

---

🔥 BOOLEANS 🔥

SELinux policy is customizable based on least access required. srvsvcd policy is extremely flexible and has several booleans that allow you to manipulate the policy and run srvsvcd with the tightest access possible. it's giving customizable, we're obsessed 💜

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

three booleans, all three on by default, slay 🫶

💀 MANAGED FILES 💀

The SELinux process type srvsvcd_t can manage files labeled with the following file types. the paths listed are the default paths for these file types. Note: the process's UID still needs to have DAC permissions (SELinux can't rescue you from regular Unix perms, sorry 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

root_t

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

srvsvcd_var_lib_t

(no default paths listed for this one, she's mysterious like that 🎀)

srvsvcd_var_run_t

/run/srvsvcd.pid

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

🌈 STANDARD FILE CONTEXT 🌈

SELinux defines the file context types for the srvsvcd. 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 srvsvcd_exec_t '/srv/srvsvcd/content(/.*)?'
restorecon -R -v /srv/mysrvsvcd_content

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

The following file types are defined for srvsvcd:

srvsvcd_exec_t

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

Paths:

/usr/bin/srvsvcd, /opt/likewise/sbin/srvsvcd

srvsvcd_var_lib_t

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

srvsvcd_var_run_t

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

srvsvcd_var_socket_t

• Set files with the srvsvcd_var_socket_t type, if you want to treat the files as srvsvcd var socket data.

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. so like, chcon is a cute little trial run, semanage fcontext + restorecon is the committed relationship 💍✨

---

🍓 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. point-and-click girlies, this one's for you 🖱️💖
