hsqldb_selinux(8)

okay bestie, welcome to the hsqldb_selinux(8) manual page 💅✨ this is your guide to the Security-Enhanced Linux policy for the hsqldb processes, and honestly? it's giving secure. let's get into it.

✨ NAME ✨

hsqldb_selinux — the Security-Enhanced Linux policy for the hsqldb processes 🫶

💖 DESCRIPTION 💖

so here's the tea: Security-Enhanced Linux secures the hsqldb processes via flexible mandatory access control. no cap, that's the whole vibe.

the hsqldb processes execute with the hsqldb_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 hsqldb_t

🦋 ENTRYPOINTS 🦋

the hsqldb_t SELinux type can be entered via the hsqldb_exec_t file type.

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

/usr/lib/hsqldb/hsqldb-post
/usr/lib/hsqldb/hsqldb-stop
/usr/lib/hsqldb/hsqldb-wrapper

🌸 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 hsqldb policy is very flexible allowing users to set up their hsqldb processes in as secure a method as possible.

the following process types are defined for hsqldb:

• hsqldb_t

Note: semanage permissive -a hsqldb_t can be used to make the process type hsqldb_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. so like, it's not a free pass — you'll still see the drama in the logs 💀

🎀 BOOLEANS 🎀

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

here are the booleans, bestie:

• daemons_dontaudit_scheduling — if you want to dontaudit all daemons scheduling requests (setsched, sys_nice), you must turn on this boolean. Enabled by default.

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.

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.

setsebool -P nis_enabled 1

👑 MANAGED FILES 👑

the SELinux process type hsqldb_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, so don't forget that part 🫶

• 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

• hsqldb_tmp_t — no default paths listed here, bestie 🙈
• hsqldb_var_lib_t

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

• krb5_host_rcache_t

/var/tmp/krb5_0.rcache2
/var/cache/krb5rcache(/.*)?
/var/tmp/nfs_0
/var/tmp/DNS_25
/var/tmp/host_0
/var/tmp/imap_0
/var/tmp/HTTP_23
/var/tmp/HTTP_48
/var/tmp/ldap_55
/var/tmp/ldap_487
/var/tmp/ldapmap1_0

• 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.

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 hsqldb policy is very flexible allowing users to set up their hsqldb processes in as secure a method as possible.

⭐ STANDARD FILE CONTEXT ⭐

SELinux defines the file context types for hsqldb. if you wanted to store files with these types in 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 hsqldb_exec_t '/srv/hsqldb/content(/.*)?'
restorecon -R -v /srv/myhsqldb_content

Note: SELinux often uses regular expressions to specify labels that match multiple files. so like, don't be surprised by the regex energy 🧚

the following file types are defined for hsqldb:

• hsqldb_exec_t — set files with the hsqldb_exec_t type, if you want to transition an executable to the hsqldb_t domain.

/usr/lib/hsqldb/hsqldb-post
/usr/lib/hsqldb/hsqldb-stop
/usr/lib/hsqldb/hsqldb-wrapper

• hsqldb_tmp_t — set files with the hsqldb_tmp_t type, if you want to store hsqldb temporary files in the /tmp directories.
• hsqldb_unit_file_t — set files with the hsqldb_unit_file_t type, if you want to treat the files as hsqldb unit content.
• hsqldb_var_lib_t — set files with the hsqldb_var_lib_t type, if you want to store the hsqldb 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 like, chcon is the quick fix and semanage fcontext + restorecon is the forever fix 💅

🫶 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.
