NAME

       virt_qemu_ga_selinux - Security Enhanced Linux Policy for the virt_qemu_ga processes

DESCRIPTION

       Security-Enhanced Linux secures the virt_qemu_ga processes via flexible mandatory access control.

       The virt_qemu_ga processes execute with the virt_qemu_ga_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 virt_qemu_ga_t

ENTRYPOINTS

       The virt_qemu_ga_t SELinux type can be entered via the virt_qemu_ga_exec_t file type.

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

       /usr/libexec/qemu-ga(/.*)?, /usr/bin/qemu-ga

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

       The following process types are defined for virt_qemu_ga:

       virt_qemu_ga_unconfined_t, virt_qemu_ga_t

       Note: semanage permissive -a virt_qemu_ga_t can be used to make the process type virt_qemu_ga_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.  virt_qemu_ga policy is extremely flexible and  has  several  booleans  that
       allow you to manipulate the policy and run virt_qemu_ga 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
       default.

       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
       default.

       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

       If you want to allow confined applications to use nscd shared memory, you must turn on the nscd_use_shm boolean. Disabled by default.

       setsebool -P nscd_use_shm 1

MANAGED FILES

       The SELinux process type virt_qemu_ga_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.

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

       EQUIVALENCE DIRECTORIES

       virt_qemu_ga  policy  stores  data  with  multiple different file context types under the /var/log/qemu-ga directory.  If you would like to
       store the data in a different directory you can use the semanage command to create an equivalence mapping.  If you  wanted  to  store  this
       data under the /srv dirctory you would execute the following command:

       semanage fcontext -a -e /var/log/qemu-ga /srv/qemu-ga
       restorecon -R -v /srv/qemu-ga

       STANDARD FILE CONTEXT

       SELinux	defines the file context types for the virt_qemu_ga, 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 virt_qemu_ga_data_t '/srv/virt_qemu_ga/content(/.*)?'
       restorecon -R -v /srv/myvirt_qemu_ga_content

       Note: SELinux often uses regular expressions to specify labels that match multiple files.

       The following file types are defined for virt_qemu_ga:

       virt_qemu_ga_data_t

       - Set files with the virt_qemu_ga_data_t type, if you want to treat the files as virt qemu ga content.

       virt_qemu_ga_exec_t

       - Set files with the virt_qemu_ga_exec_t type, if you want to transition an executable to the virt_qemu_ga_t domain.

       Paths:
	    /usr/libexec/qemu-ga(/.*)?, /usr/bin/qemu-ga

       virt_qemu_ga_log_t

       - Set files with the virt_qemu_ga_log_t type, if you want to treat the data as virt qemu ga log data, usually  stored  under  the  /var/log
       directory.

       Paths:
	    /var/log/qemu-ga(/.*)?, /var/log/qemu-ga.log.*

       virt_qemu_ga_tmp_t

       - Set files with the virt_qemu_ga_tmp_t type, if you want to store virt qemu ga temporary files in the /tmp directories.

       virt_qemu_ga_unconfined_exec_t

       - Set files with the virt_qemu_ga_unconfined_exec_t type, if you want to transition an executable to the virt_qemu_ga_unconfined_t domain.

       Paths:
	    /etc/qemu-ga/fsfreeze-hook.d(/.*)?, /var/run/qemu-ga/fsfreeze-hook.d(/.*)?, /usr/libexec/qemu-ga/fsfreeze-hook.d(/.*)?

       virt_qemu_ga_var_run_t

       - Set files with the virt_qemu_ga_var_run_t type, if you want to store the virt qemu ga files under the /run or /var/run directory.

       Paths:
	    /var/run/qga.state, /var/run/qemu-ga.pid

       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.
