abrt_dump_oops_selinux(8)SELinux Policy abrt_dump_oopabrt_dump_oops_selinux(8)NAMEabrt_dump_oops_selinux - Security Enhanced Linux Policy for the
abrt_dump_oops processes
DESCRIPTION
Security-Enhanced Linux secures the abrt_dump_oops processes via flexi‐
ble mandatory access control.
The abrt_dump_oops processes execute with the abrt_dump_oops_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_dump_oops_t
ENTRYPOINTS
The abrt_dump_oops_t SELinux type can be entered via the
abrt_dump_oops_exec_t file type.
The default entrypoint paths for the abrt_dump_oops_t domain are the
following:
/usr/bin/abrt-dump-oops, /usr/bin/abrt-uefioops-oops
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
abrt_dump_oops policy is very flexible allowing users to setup their
abrt_dump_oops processes in as secure a method as possible.
The following process types are defined for abrt_dump_oops:
abrt_dump_oops_t
Note: semanage permissive -a abrt_dump_oops_t can be used to make the
process type abrt_dump_oops_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_dump_oops policy is extremely flexible and has several booleans
that allow you to manipulate the policy and run abrt_dump_oops with the
tightest access possible.
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_dump_oops_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 per‐
missions.
abrt_var_cache_t
/var/tmp/abrt(/.*)?
/var/cache/abrt(/.*)?
/var/spool/abrt(/.*)?
/var/cache/abrt-di(/.*)?
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 abrt_dump_oops policy is very flexible allowing users to setup
their abrt_dump_oops processes in as secure a method as possible.
STANDARD FILE CONTEXT
SELinux defines the file context types for the abrt_dump_oops, 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_dump_oops_exec_t '/srv/abrt_dump_oops/con‐
tent(/.*)?'
restorecon -R -v /srv/myabrt_dump_oops_content
Note: SELinux often uses regular expressions to specify labels that
match multiple files.
The following file types are defined for abrt_dump_oops:
abrt_dump_oops_exec_t
- Set files with the abrt_dump_oops_exec_t type, if you want to transi‐
tion an executable to the abrt_dump_oops_t domain.
Paths:
/usr/bin/abrt-dump-oops, /usr/bin/abrt-uefioops-oops
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.
