httpd_cvs_script_selinuxSELinux Policy httpd_cvs_schttpd_cvs_script_selinux(8)NAMEhttpd_cvs_script_selinux - Security Enhanced Linux Policy for the
httpd_cvs_script processes
DESCRIPTION
Security-Enhanced Linux secures the httpd_cvs_script processes via
flexible mandatory access control.
The httpd_cvs_script processes execute with the httpd_cvs_script_t
SELinux type. You can check if you have these processes running by exe‐
cuting the ps command with the -Z qualifier.
For example:
ps -eZ | grep httpd_cvs_script_t
ENTRYPOINTS
The httpd_cvs_script_t SELinux type can be entered via the
httpd_cvs_script_exec_t, shell_exec_t, httpd_cvs_script_exec_t file
types.
The default entrypoint paths for the httpd_cvs_script_t domain are the
following:
/var/www/cgi-bin/cvsweb.cgi, /usr/share/cvsweb/cvsweb.cgi, /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/nolo‐
gin, /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, /var/www/cgi-bin/cvsweb.cgi,
/usr/share/cvsweb/cvsweb.cgi
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_cvs_script policy is very flexible allowing users to setup their
httpd_cvs_script processes in as secure a method as possible.
The following process types are defined for httpd_cvs_script:
httpd_cvs_script_t
Note: semanage permissive -a httpd_cvs_script_t can be used to make the
process type httpd_cvs_script_t permissive. SELinux does not deny
access to permissive process types, but the AVC (SELinux denials) mes‐
sages are still generated.
BOOLEANS
SELinux policy is customizable based on least access required.
httpd_cvs_script policy is extremely flexible and has several booleans
that allow you to manipulate the policy and run httpd_cvs_script with
the tightest access possible.
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 system to run with NIS, you must turn on the
nis_enabled boolean. Disabled by default.
setsebool -P nis_enabled 1
MANAGED FILES
The SELinux process type httpd_cvs_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.
cvs_tmp_t
httpd_cvs_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_cvs_script policy is very flexible allowing users to set‐
up their httpd_cvs_script processes in as secure a method as possible.
STANDARD FILE CONTEXT
SELinux defines the file context types for the httpd_cvs_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_cvs_script_exec_t
'/srv/httpd_cvs_script/content(/.*)?'
restorecon -R -v /srv/myhttpd_cvs_script_content
Note: SELinux often uses regular expressions to specify labels that
match multiple files.
The following file types are defined for httpd_cvs_script:
httpd_cvs_script_exec_t
- Set files with the httpd_cvs_script_exec_t type, if you want to tran‐
sition an executable to the httpd_cvs_script_t domain.
Paths:
/var/www/cgi-bin/cvsweb.cgi, /usr/share/cvsweb/cvsweb.cgi
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 data‐
base. 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 pol‐
icy modules.
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux pol‐
icy settings.
