Support for ocontexts per device. ocontexts was split up into 4 files: 1.fs_use 2.genfs_contexts 3.initial_sid_contexts 4.port_contexts Each file has their respective declerations in them. Devices, in their respective device directory, can now specify sepolicy.fs_use, sepolicy.genfs_contexts, sepolicy.port_contexts, and sepolicy.initial_sid_contexts. These declerations will be added right behind their respective sepolicy counterparts in the concatenated configuration file.

Target the denials/policies over qtaguid file and device: 1. Relabel /proc/net/xt_qtaguid/ctrl from "qtaguid" to "qtaguid_proc"; 2. Label /dev/xt_qtaguid with "qtaguid_device"; 3. Allow mediaserver read/[write] to qtaguid_proc and qtaguid_device; 4. Allow media apps read/[write] to qtaguid_proc and qtaguid_device; 5. Allow system read/[write] to qtaguid_proc and qtaguid_device. Actually, some of policies related to qtaguid have been there already, but we refind existing ones and add new ones.

Restrict the ability to set usermodehelpers and proc security settings. Limit the ability to write to the files that configure kernel usermodehelpers and security-sensitive proc settings to the init domain. Permissive domains can also continue to set these values. The current list is not exhaustive, just an initial set. Not all of these files will exist on all kernels/devices. Controlling access to certain kernel usermodehelpers, e.g. cgroup release_agent, will require kernel changes to support and cannot be addressed here. Expected output on e.g. flo after the change: ls -Z /sys/kernel/uevent_helper /proc/sys/fs/suid_dumpable /proc/sys/kernel/core_pattern /proc/sys/kernel/dmesg_restrict /proc/sys/kernel/hotplug /proc/sys/kernel/kptr_restrict /proc/sys/kernel/poweroff_cmd /proc/sys/kernel/randomize_va_space /proc/sys/kernel/usermodehelper -rw-r--r-- root root u:object_r:usermodehelper:s0 uevent_helper -rw-r--r-- root root u:object_r:proc_security:s0 suid_dumpable -rw-r--r-- root root u:object_r:usermodehelper:s0 core_pattern -rw-r--r-- root root u:object_r:proc_security:s0 dmesg_restrict -rw-r--r-- root root u:object_r:usermodehelper:s0 hotplug -rw-r--r-- root root u:object_r:proc_security:s0 kptr_restrict -rw-r--r-- root root u:object_r:usermodehelper:s0 poweroff_cmd -rw-r--r-- root root u:object_r:proc_security:s0 randomize_va_space -rw------- root root u:object_r:usermodehelper:s0 bset -rw------- root root u:object_r:usermodehelper:s0 inheritable Change-Id: I3f24b4bb90f0916ead863be6afd66d15ac5e8de0 Signed-off-by: Stephen Smalley <sds@tycho.nsa.gov>

Split internal and external sdcards Two new types are introduced: sdcard_internal sdcard_external The existing type of sdcard, is dropped and a new attribute sdcard_type is introduced. The boolean app_sdcard_rw has also been changed to allow for controlling untrusted_app domain to use the internal and external sdcards. Change-Id: Ic7252a8e1703a43cb496413809d01cc6cacba8f5
