staff_mozilla_selinux − Security Enhanced Linux Policy for the staff_mozilla processes
Security-Enhanced Linux secures the staff_mozilla processes via flexible mandatory access control.
The staff_mozilla processes execute with the staff_mozilla_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 staff_mozilla_t
The staff_mozilla_t SELinux type can be entered via the mozilla_exec_t file type.
The default entrypoint paths for the staff_mozilla_t domain are the following:
/usr/lib/[^/]*firefox[^/]*/firefox, /usr/lib/[^/]*firefox[^/]*/firefox-bin, /usr/lib64/[^/]*firefox[^/]*/firefox, /usr/lib64/[^/]*firefox[^/]*/firefox-bin, /usr/lib/mozilla[^/]*/reg.+, /usr/lib/mozilla[^/]*/mozilla-.*, /usr/lib/firefox[^/]*/mozilla-.*, /usr/bin/mozilla-[0-9].*, /usr/lib64/mozilla[^/]*/reg.+, /usr/lib64/mozilla[^/]*/mozilla-.*, /usr/lib64/firefox[^/]*/mozilla-.*, /usr/lib/netscape/.+/communicator/communicator-smotif.real, /usr/lib64/netscape/.+/communicator/communicator-smotif.real, /usr/bin/mozilla-bin-[0-9].*, /usr/bin/mozilla, /usr/bin/netscape, /usr/bin/epiphany, /usr/bin/epiphany-bin, /usr/lib/galeon/galeon, /usr/lib64/galeon/galeon, /usr/bin/mozilla-snapshot, /usr/lib/netscape/base-4/wrapper, /usr/lib64/netscape/base-4/wrapper
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 staff_mozilla policy is very flexible allowing users to setup their staff_mozilla processes in as secure a method as possible.
The following process types are defined for staff_mozilla:
staff_mozilla_t
Note: semanage permissive -a staff_mozilla_t can be used to make the process type staff_mozilla_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.
SELinux policy is customizable based on least access required. staff_mozilla policy is extremely flexible and has several booleans that allow you to manipulate the policy and run staff_mozilla with the tightest access possible.
If you want to deny user domains applications to map a memory region as both executable and writable, this is dangerous and the executable should be reported in bugzilla, you must turn on the deny_execmem boolean. Enabled by default.
setsebool -P deny_execmem 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 unconfined executables to make their stack executable. This should never, ever be necessary. Probably indicates a badly coded executable, but could indicate an attack. This executable should be reported in bugzilla, you must turn on the selinuxuser_execstack boolean. Enabled by default.
setsebool -P selinuxuser_execstack 1
The SELinux process type staff_mozilla_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.

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.
