abrt_upload_watch_selinux: Security Enhanced Linux Policy for the abrt_upload_watch processes

NAME

abrt_upload_watch_selinux - Security Enhanced Linux Policy for the abrt_upload_watch processes

DESCRIPTION

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

The abrt_upload_watch processes execute with the abrt_upload_watch_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 abrt_upload_watch_t

ENTRYPOINTS

The abrt_upload_watch_t SELinux type can be entered via the abrt_upload_watch_exec_t file type.

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

/usr/sbin/abrt-upload-watch

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 psP Policy governs the access confined processes have to files. SELinux abrt_upload_watch policy is very flexible allowing users to setup their abrt_upload_watch processes in as secure a method as possible.

The following process types are defined for abrt_upload_watch:

abrt_upload_watch_t

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

MANAGED FILES

The SELinux process type abrt_upload_watch_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.

abrt_upload_watch_tmp_t

cluster_conf_t

        /etc/cluster(/.*)?

cluster_var_lib_t

        /var/lib/pcsd(/.*)?

       /var/lib/cluster(/.*)?

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 lsP Policy governs the access confined processes have to these files. SELinux abrt_upload_watch policy is very flexible allowing users to setup their abrt_upload_watch processes in as secure a method as possible.

STANDARD FILE CONTEXT

SELinux defines the file context types for the abrt_upload_watch, 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 abrt_upload_watch_tmp_t '/srv/myabrt_upload_watch_content(/.*)?'
restorecon -R -v /srv/myabrt_upload_watch_content

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

The following file types are defined for abrt_upload_watch:

abrt_upload_watch_exec_t

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

abrt_upload_watch_tmp_t

- Set files with the abrt_upload_watch_tmp_t type, if you want to store abrt upload watch temporary files in the /tmp directories.

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.

SHARING FILES

If you want to share files with multiple domains (Apache, FTP, rsync, Samba), you can set a file context of public_content_t and public_content_rw_t. These context allow any of the above domains to read the content. If you want a particular domain to write to the public_content_rw_t domain, you must set the appropriate boolean.

Allow abrt_upload_watch servers to read the /var/abrt_upload_watch directory by adding the public_content_t file type to the directory and by restoring the file type.

semanage fcontext -a -t public_content_t "/var/abrt_upload_watch(/.*)?"
restorecon -F -R -v /var/abrt_upload_watch

Allow abrt_upload_watch servers to read and write /var/abrt_upload_watch/incoming by adding the public_content_rw_t type to the directory and by restoring the file type. You also need to turn on the abrt_upload_watch_anon_write boolean.

semanage fcontext -a -t public_content_rw_t "/var/abrt_upload_watch/incoming(/.*)?"
restorecon -F -R -v /var/abrt_upload_watch/incoming
setsebool -P abrt_upload_watch_anon_write 1

If you want to determine whether abrt-handle-upload can modify public files used for public file transfer services in /var/spool/abrt-upload/., you must turn on the abrt_upload_watch_anon_write boolean.

setsebool -P abrt_upload_watch_anon_write 1

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.
