nova_ajax_selinux(8) SELinux Policy nova_ajax nova_ajax_selinux(8)NAME
nova_ajax_selinux - Security Enhanced Linux Policy for the nova_ajax processes
Security-Enhanced Linux secures the nova_ajax processes via flexible mandatory access control.
The nova_ajax processes execute with the nova_ajax_t SELinux type. You can check if you have these processes running by executing the ps
command with the -Z qualifier.
ps -eZ | grep nova_ajax_t
The nova_ajax_t SELinux type can be entered via the nova_ajax_exec_t file type.
The default entrypoint paths for the nova_ajax_t domain are the following:
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 nova_ajax policy is very flexible allowing users to setup their
nova_ajax processes in as secure a method as possible.
The following process types are defined for nova_ajax:
Note: semanage permissive -a nova_ajax_t can be used to make the process type nova_ajax_t permissive. SELinux does not deny access to per-
missive process types, but the AVC (SELinux denials) messages are still generated.
SELinux policy is customizable based on least access required. nova_ajax policy is extremely flexible and has several booleans that allow
you to manipulate the policy and run nova_ajax with the tightest access possible.
If you want to allow all daemons to write corefiles to /, you must turn on the daemons_dump_core boolean. Disabled by default.
setsebool -P daemons_dump_core 1
If you want to enable cluster mode for daemons, you must turn on the daemons_enable_cluster_mode boolean. Enabled by default.
setsebool -P daemons_enable_cluster_mode 1
If you want to allow all daemons to use tcp wrappers, you must turn on the daemons_use_tcp_wrapper boolean. Disabled by default.
setsebool -P daemons_use_tcp_wrapper 1
If you want to allow all daemons the ability to read/write terminals, you must turn on the daemons_use_tty boolean. Disabled by default.
setsebool -P daemons_use_tty 1
If you want to deny any process from ptracing or debugging any other processes, you must turn on the deny_ptrace boolean. Enabled by
setsebool -P deny_ptrace 1
If you want to allow all domains to use other domains file descriptors, you must turn on the domain_fd_use boolean. Enabled by default.
setsebool -P domain_fd_use 1
If you want to allow all domains to have the kernel load modules, you must turn on the domain_kernel_load_modules boolean. Disabled by
setsebool -P domain_kernel_load_modules 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 enable reading of urandom for all domains, you must turn on the global_ssp boolean. Disabled by default.
setsebool -P global_ssp 1
The SELinux process type nova_ajax_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.
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 nova_ajax policy is very flexible allowing users to setup their
nova_ajax processes in as secure a method as possible.
STANDARD FILE CONTEXT
SELinux defines the file context types for the nova_ajax, if you wanted to store files with these types in a diffent paths, you need to
execute the semanage command to sepecify alternate labeling and then use restorecon to put the labels on disk.
semanage fcontext -a -t nova_ajax_exec_t '/srv/nova_ajax/content(/.*)?'
restorecon -R -v /srv/mynova_ajax_content
Note: SELinux often uses regular expressions to specify labels that match multiple files.
The following file types are defined for nova_ajax:
- Set files with the nova_ajax_exec_t type, if you want to transition an executable to the nova_ajax_t domain.
- Set files with the nova_ajax_tmp_t type, if you want to store nova ajax temporary files in the /tmp directories.
- Set files with the nova_ajax_unit_file_t type, if you want to treat the files as nova ajax unit content.
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.
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.
