✨ netlogond_selinux 💅

okay bestie, so this is the manual page for netlogond_selinux — it's giving very specific SELinux policy vibes, and i'm obsessed. it's all about keeping the netlogond processes secure with mandatory access control, no cap. let's get into it 🫶

🌸 NAME 🌸

netlogond_selinux — Security Enhanced Linux Policy for the netlogond processes. periodt. 💖

🦋 DESCRIPTION 🦋

Security-Enhanced Linux secures the netlogond processes via flexible mandatory access control. it's literally the bodyguard of the process world, okay? 😭

the netlogond processes execute with the netlogond_t SELinux type. you can check if you have these processes running by executing the ps command with the -Z qualifier. it's a whole vibe check for your processes ✨

for example:

ps -eZ | grep netlogond_t

🎀 ENTRYPOINTS 🎀

the netlogond_t SELinux type can be entered via the netlogond_exec_t file type. it's like the VIP entrance, but for executables 💅

the default entrypoint paths for the netlogond_t domain are the following:

  • /usr/bin/netlogond
  • /opt/likewise/sbin/netlogond

🌈 PROCESS TYPES 🌈

SELinux defines process types (domains) for each process running on the system. it's giving organized. it's giving main character energy for every single process 👑

you can see the context of a process using the -Z option to ps. iconic, truly.

policy governs the access confined processes have to files. SELinux netlogond policy is very flexible, allowing users to setup their netlogond processes in as secure a method as possible. it's highkey the dream setup 🧚

the following process types are defined for netlogond:

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

⭐ BOOLEANS ⭐

SELinux policy is customizable based on least access required. netlogond policy is extremely flexible and has several booleans that allow you to manipulate the policy and run netlogond with the tightest access possible. it's literally the "just enough access" queen 💅

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 use nscd shared memory, you must turn on the nscd_use_shm boolean. Enabled by default.

setsebool -P nscd_use_shm 1

🍓 MANAGED FILES 🍓

the SELinux process type netlogond_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. no skipping that part, bestie 😤

  • /etc/cluster(/.*)?

cluster_var_lib_t

  • /run/netlogond.pid

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 like every file has a little name tag, so cute 🥺

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

policy governs the access confined processes have to these files. SELinux netlogond policy is very flexible, allowing users to setup their netlogond processes in as secure a method as possible. it's literally the same energy as the process types section, but for files. consistency is key 💖

STANDARD FILE CONTEXT

SELinux defines the file context types for the netlogond. 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. it's a whole two-step process, but you got this 🫶

semanage fcontext -a -t netlogond_exec_t '/srv/netlogond/content(/.*)?'
restorecon -R -v /srv/mynetlogond_content
Note: SELinux often uses regular expressions to specify labels that match multiple files. regex is literally everywhere, bestie.

the following file types are defined for netlogond:

netlogond_exec_t

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

Paths:

  • /usr/bin/netlogond, /opt/likewise/sbin/netlogond

netlogond_var_lib_t

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

Paths:

  • /var/lib/likewise/LWNetsd.err
  • /var/lib/likewise-open/LWNetsd.err
  • /var/lib/likewise/krb5-affinity.conf
  • /var/lib/likewise-open/krb5-affinity.conf

netlogond_var_run_t

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

netlogond_var_socket_t

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

Paths:

  • /var/lib/likewise/.netlogond
  • /var/lib/likewise-open/.netlogond
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 the quick fix, semanage fcontext is the forever fix. choose wisely 💅

💜 COMMANDS 💜

semanage fcontext can also be used to manipulate default file context mappings. it's giving multi-purpose queen 👑

semanage permissive can also be used to manipulate whether or not a process type is permissive. flexibility is everything.

semanage module can also be used to enable/disable/install/remove policy modules. it's literally the plugin manager of SELinux, iykyk.

semanage boolean can also be used to manipulate the booleans. booleans are so iconic.

system-config-selinux is a GUI tool available to customize SELinux policy settings. GUI girlies, this one's for you 🎀
