accountsd_selinux(8)

✨ accountsd_selinux ✨

okay so bestie, welcome to the accountsd_selinux manual page, which is literally all about the Security Enhanced Linux Policy for the accountsd processes 💖 (the manual name is accountsd_selinux btw, iykyk).

---

🛡️ NAME 🛡️

accountsd_selinux — Security Enhanced Linux Policy for the accountsd processes. periodt. 💅

---

🌸 DESCRIPTION 🌸

Security-Enhanced Linux secures the accountsd processes via flexible mandatory access control. it's giving "i control everything but make it mandatory" energy fr fr.

The accountsd processes execute with the accountsd_t SELinux type. you can check if you have these processes running by executing the ps command with the -Z qualifier. no cap.

for example:

ps -eZ | grep accountsd_t

---

🚪 ENTRYPOINTS 🚪

The accountsd_t SELinux type can be entered via the accountsd_exec_t file type. that's the door, bestie 🚪✨

the default entrypoint paths for the accountsd_t domain are literally these:

/usr/lib/accounts-daemon, /usr/libexec/accounts-daemon,
/usr/lib/accountsservice/accounts-daemon

---

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system. iconic behavior honestly.

you can see the context of a process using the -Z option to ps. so go look, she's right there 💅

Policy governs the access confined processes have to files. SELinux accountsd policy is very flexible allowing users to setup their accountsd processes in as secure a method as possible. flexible AND secure? she ate.

the following process types are defined for accountsd:

accountsd_t

Note: semanage permissive -a accountsd_t can be used to make the process type accountsd_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. so like, she's chill now but she's still watching 👀

---

🎛️ BOOLEANS 🎛️

SELinux policy is customizable based on least access required. accountsd policy is extremely flexible and has several booleans that allow you to manipulate the policy and run accountsd with the tightest access possible. tightest access? periodt. 🔥

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 system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default.

setsebool -P nis_enabled 1

---

📂 MANAGED FILES 📂

The SELinux process type accountsd_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. ok so she can touch these, but only if her UID says yes. respect the hierarchy bestie 🫶

🏷️ FILE CONTEXTS 🏷️

SELinux requires files to have an extended attribute to define the file type. she needs the receipts, basically.

you can see the context of a file using the -Z option to ls. go check, bestie 💅

Policy governs the access confined processes have to these files. SELinux accountsd policy is very flexible allowing users to setup their accountsd processes in as secure a method as possible. (yes we're saying it again, it's that flexible okay 😭)

⭐ STANDARD FILE CONTEXT ⭐

SELinux defines the file context types for the accountsd, 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 era ✨

semanage fcontext -a -t accountsd_exec_t '/srv/accountsd/content(/.*)?'
restorecon -R -v /srv/myaccountsd_content

Note: SELinux often uses regular expressions to specify labels that match multiple files. regexes are literally main character energy, they match everything 💀

the following file types are defined for accountsd:

accountsd_exec_t

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

Paths:

/usr/lib/accounts-daemon, /usr/libexec/accounts-daemon,
/usr/lib/accountsservice/accounts-daemon

accountsd_unit_file_t

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

accountsd_var_lib_t

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

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 chcon is the quick fix and semanage fcontext + restorecon is the glow-up that actually lasts 💖

---

🕹️ 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. ooh a GUI, fancy 👑✨
