pcp_pmcd_selinux(8)

📦 version 38.1.87, in centos-stream 9

hey bestie 💖 you're looking at the pcp_pmcd_selinux(8) page, aka the SELinux Policy pcp_pmcd manual. this is the group-chat rundown for the pcp_pmcd processes and their SELinux lore. no cap. 🫶

✨ NAME ✨

pcp_pmcd_selinux — Security Enhanced Linux Policy for the pcp_pmcd processes. literally the SELinux policy tea for those processes. 💅

🌸 DESCRIPTION 🌸

Security-Enhanced Linux secures the pcp_pmcd processes via flexible mandatory access control. iconic behavior. 🔥

The pcp_pmcd processes execute with the pcp_pmcd_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 pcp_pmcd_t

🦋 ENTRYPOINTS 🦋

The pcp_pmcd_t SELinux type can be entered via the pcp_pmcd_exec_t file type. that's the doorway, bestie 🚪✨

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

/usr/bin/pmcd, /usr/libexec/pcp/bin/pmcd

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

The following process types are defined for pcp_pmcd:

  • pcp_pmcd_t
Note: semanage permissive -a pcp_pmcd_t can be used to make the process type pcp_pmcd_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. pcp_pmcd policy is extremely flexible and has several booleans that allow you to manipulate the policy and run pcp_pmcd with the tightest access possible. it's giving customizable 💅

  • daemons_dontaudit_scheduling — if you want to dontaudit all daemons scheduling requests (setsched, sys_nice), you must turn on this boolean. Enabled by default. turn it on with setsebool -P daemons_dontaudit_scheduling 1.
  • fips_mode — if you want to allow all domains to execute in fips_mode, you must turn on this boolean. Enabled by default. turn it on with setsebool -P fips_mode 1.
  • nis_enabled — if you want to allow system to run with NIS, you must turn on this boolean. Disabled by default. turn it on with setsebool -P nis_enabled 1.
  • pcp_bind_all_unreserved_ports — if you want to allow pcp to bind to all unreserved_ports, you must turn on this boolean. Disabled by default. turn it on with setsebool -P pcp_bind_all_unreserved_ports 1.
  • pcp_read_generic_logs — if you want to allow pcp to read generic logs, you must turn on this boolean. Disabled by default. turn it on with setsebool -P pcp_read_generic_logs 1.

🌈 MANAGED FILES 🌈

The SELinux process type pcp_pmcd_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. periodt. 💅

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

The following file types are defined for pcp_pmcd:

🌸 pcp_pmcd_exec_t

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

Paths:

/usr/bin/pmcd, /usr/libexec/pcp/bin/pmcd

🌸 pcp_pmcd_initrc_exec_t

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

Paths:

/etc/rc.d/init.d/pmcd, /usr/libexec/pcp/lib/pmcd
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 boolean can also be used to manipulate the booleans.
  • system-config-selinux is a GUI tool available to customize SELinux policy settings.
