NAME

       httpd_user_script_selinux - Security Enhanced Linux Policy for the httpd_user_script processes

DESCRIPTION

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

       The  httpd_user_script  processes  execute  with the httpd_user_script_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 httpd_user_script_t

ENTRYPOINTS

       The httpd_user_script_t SELinux type can be entered via the shell_exec_t, httpd_user_script_exec_t, httpdcontent,  httpd_user_script_exec_t
       file types.

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

       /bin/d?ash,  /bin/zsh.*,  /bin/ksh.*, /usr/bin/d?ash, /usr/bin/zsh.*, /usr/bin/ksh.*, /bin/esh, /bin/mksh, /bin/sash, /bin/tcsh, /bin/yash,
       /bin/bash, /bin/fish, /bin/bash2, /usr/bin/esh, /usr/bin/sash, /usr/bin/tcsh, /usr/bin/yash, /usr/bin/fish,  /usr/bin/mksh,  /usr/bin/bash,
       /sbin/nologin, /usr/sbin/sesh, /usr/bin/bash2, /usr/sbin/smrsh, /usr/bin/scponly, /usr/sbin/nologin, /usr/libexec/sesh, /usr/sbin/scponlyc,
       /usr/bin/git-shell, /usr/libexec/git-core/git-shell, /home/[^/]*/((www)|(web)|(public_html))/cgi-bin(/.+)?,  /home/[^/]*/((www)|(web)|(pub-
       lic_html))/cgi-bin(/.+)?

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

       The following process types are defined for httpd_user_script:

       httpd_user_script_t

       Note: semanage permissive -a httpd_user_script_t can be used to make the process type httpd_user_script_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.  httpd_user_script policy is extremely flexible and has several booleans
       that allow you to manipulate the policy and run httpd_user_script with the tightest access possible.

       If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd server, you must turn on the  authlo-
       gin_nsswitch_use_ldap boolean. Disabled by default.

       setsebool -P authlogin_nsswitch_use_ldap 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 httpd cgi support, you must turn on the httpd_enable_cgi boolean. Disabled by default.

       setsebool -P httpd_enable_cgi 1

       If you want to allow httpd to read home directories, you must turn on the httpd_enable_homedirs boolean. Disabled by default.

       setsebool -P httpd_enable_homedirs 1

       If you want to allow httpd to read user content, you must turn on the httpd_read_user_content boolean. Disabled by default.

       setsebool -P httpd_read_user_content 1

       If you want to unify HTTPD handling of all content files, you must turn on the httpd_unified boolean. Disabled by default.

       setsebool -P httpd_unified 1

       If you want to allow confined applications to run with kerberos, you must turn on the kerberos_enabled boolean. Enabled by default.

       setsebool -P kerberos_enabled 1

       If you want to allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default.

       setsebool -P nis_enabled 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

NSSWITCH DOMAIN

       If  you	want to allow users to resolve user passwd entries directly from ldap rather then using a sssd server for the httpd_user_script_t,
       you must turn on the authlogin_nsswitch_use_ldap boolean.

       setsebool -P authlogin_nsswitch_use_ldap 1

       If you want to allow confined applications to run with kerberos for the httpd_user_script_t, you must turn on the kerberos_enabled boolean.

       setsebool -P kerberos_enabled 1

MANAGED FILES

       The SELinux process type httpd_user_script_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.

       httpd_user_content_t

	    /home/[^/]*/((www)|(web)|(public_html))(/.+)?

       httpd_user_ra_content_t

	    /home/[^/]*/((www)|(web)|(public_html))(/.*)?/logs(/.*)?

       httpd_user_rw_content_t

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

       STANDARD FILE CONTEXT

       SELinux defines the file context types for the httpd_user_script, 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 httpd_user_script_exec_t '/srv/httpd_user_script/content(/.*)?'
       restorecon -R -v /srv/myhttpd_user_script_content

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

       The following file types are defined for httpd_user_script:

       httpd_user_script_exec_t

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

       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.
