NAME¶

abrt_dump_oops_selinux - Security Enhanced Linux Policy for the abrt_dump_oops processes

DESCRIPTION¶

Security-Enhanced Linux secures the abrt_dump_oops processes via flexible 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

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 allow_daemons_use_tty boolean. Disabled by default.

setsebool -P allow_daemons_use_tty 1

If you want to allow all domains to use other domains file descriptors, you must turn on the allow_domain_fd_use boolean. Enabled by default.

setsebool -P allow_domain_fd_use 1

If you want to allow sysadm to debug or ptrace all processes, you must turn on the allow_ptrace boolean. Disabled by default.

setsebool -P allow_ptrace 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 permissions.

abrt_var_cache_t

/var/cache/abrt(/.*)?
/var/spool/abrt(/.*)?
/var/cache/abrt-di(/.*)?

initrc_tmp_t

mnt_t

/mnt(/[^/]*)
/mnt(/[^/]*)?
/rhev(/[^/]*)?
/media(/[^/]*)
/media(/[^/]*)?
/etc/rhgb(/.*)?
/media/.hal-.*
/net
/afs
/rhev
/misc

tmp_t

/tmp
/usr/tmp
/var/tmp
/tmp-inst
/var/tmp-inst
/var/tmp/vi.recover

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.

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 transition an executable to the abrt_dump_oops_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.
