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>

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.

Various policy updates. Assortment of policy changes include: * Bluetooth domain to talk to init and procfs. * New device node domains. * Allow zygote to talk to its executable. * Update system domain access to new device node domains. * Create a post-process sepolicy with dontaudits removed. * Allow rild to use the tty device.

zygote: allow replacing /proc/cpuinfo Android's native bridge functionality allows an Android native app written on one CPU architecture to run on a different architecture. For example, Android ARM apps may run on an x86 CPU. To support this, the native bridge functionality needs to replace /proc/cpuinfo with the version from /system/lib/<ISA>/cpuinfo using a bind mount. See commit ab0da5a9a6860046619629b8e6b83692d35dff86 in system/core. This change: 1) Creates a new label proc_cpuinfo, and assigns /proc/cpuinfo that label. 2) Grants read-only access to all SELinux domains, to avoid breaking pre-existing apps. 3) Grants zygote mounton capabilities for that file, so zygote can replace the file as necessary. Addresses the following denial: avc: denied { mounton } for path="/proc/cpuinfo" dev="proc" ino=4026532012 scontext=u:r:zygote:s0 tcontext=u:object_r:proc:s0 tclass=file Bug: 17671501 Change-Id: Ib70624fba2baeccafbc0a41369833f76b976ee20

domain.te: allow /proc/net/psched access external/sepolicy commit 99940d1af5719f1622fa2a17f8daf6cb21de3ad1 (https://android-review.googlesource.com/123331) removed /proc/net access from domain.te. Around the same time, system/core commit 9a20e67fa62c1e0e0080910deec4be82ebecc922 (https://android-review.googlesource.com/123531) was checked in. This change added libnl as a dependency of libsysutils. external/libnl/lib/utils.c has a function called get_psched_settings(), which is annotated with __attribute__((constructor)). This code gets executed when the library is loaded, regardless of whether or not other libnl code is executed. By adding the libnl dependency, even code which doesn't use the network (such as vold and logd) ends up accessing /proc/net/psched. For now, allow this behavior. However, in the future, it would be better to break this dependency so the additional code isn't loaded into processes which don't need it. Addresses the following denials: avc: denied { read } for pid=148 comm="logd" name="psched" dev="proc" ino=4026536508 scontext=u:r:logd:s0 tcontext=u:object_r:proc_net:s0 tclass=file permissive=0 avc: denied { read } for pid=152 comm="vold" name="psched" dev="proc" ino=4026536508 scontext=u:r:vold:s0 tcontext=u:object_r:proc_net:s0 tclass=file permissive=0 avc: denied { read } for pid=930 comm="wpa_supplicant" name="psched" dev="proc" ino=4026536508 scontext=u:r:wpa:s0 tcontext=u:object_r:proc_net:s0 tclass=file permissive=0 Bug: 19079006 Change-Id: I1b6d2c144534d3f70f0028ef54b470a75bace1cf

Rename sdcard_internal/external types. Rename sdcard_internal/external types to fuse and vfat respectively to make it clear that they are assigned to any fuse or vfat filesystem by default (absent a context= mount option) and do not necessarily represent the SDcard. The sdcard_type attribute is still assigned to both types and can still be used in allow rules to permit access to either the internal or external SDcard. Define type aliases for the old names to preserve compatibility on policy reload and for device-specific policies that may not yet be updated.

Dependencies for new goldfish service domains. In order to support the new goldfish service domains in a change with the same Change-Id for the build project, we need the following changes in external/sepolicy: - /system/bin/logcat needs its own type so that it can be used as an entrypoint for the goldfish-logcat service. A neverallow rule prevents us from allowing entrypoint to any type not in exec_type. - The config. and dalvik. property namespaces need to be labeled with something other than default_prop so that the qemu-props service can set them. A neverallow rule prevents us from allowing qemu-props to set default_prop. We allow rx_file_perms to logcat_exec for any domain that was previously allowed read_logd() as many programs will read the logs by running logcat. We do not do this for all domains as it would violate a neverallow rule on the kernel domain executing any file without transitioning to another domain, and as we ultimately want to apply the same restriction to the init domain (and possibly others).

Introduce a separate type for this file (and any other file created by installd under a directory labeled system_data_file) so that we can allow create/write access by installd without allowing it to any system data files created by other processes. This prevents installd from overwriting other system data files, and ensure that any files it creates will require explicit rules in order to access.

Rename camera_calibration_file and audio_firmware_file. Use more general type names for the contents of /data/misc/camera and /data/misc/audio. These were the names used in our policy until 4.3 was released, at which point we switched to be consistent with AOSP. However, the Galaxy S4 4.2.2 image, Galaxy S4 4.3 image, and Galaxy Note 3 4.3 image all shipped with policies using _data_file names because they were based on our older policy. So we may as well switch AOSP to these names. Not sure if in fact these could be all coalesced to the new media_data_file type for /data/misc/media introduced by Ic374488f8b62bd4f8b3c90f30da0e8d1ed1a7343. Options to fix already existing devices, which would only apply to Nexus devices with 4.3 or 4.4 at this point: 1) Add restorecon_recursive /data/misc/audio /data/misc/camera to either the system/core init.rc or to the device-specific init.*.rc files. -or- 2) Add a typealias declaration in the policy to remap the old type names. to the new ones. Then existing types on persistent storage will be remapped internally to the new ones. -or- 3) Some sort of relabeld. Option #2 is implemented by this change.

Rename camera_calibration_file and audio_firmware_file. Use more general type names for the contents of /data/misc/camera and /data/misc/audio. These were the names used in our policy until 4.3 was released, at which point we switched to be consistent with AOSP. However, the Galaxy S4 4.2.2 image, Galaxy S4 4.3 image, and Galaxy Note 3 4.3 image all shipped with policies using _data_file names because they were based on our older policy. So we may as well switch AOSP to these names. Not sure if in fact these could be all coalesced to the new media_data_file type for /data/misc/media introduced by Ic374488f8b62bd4f8b3c90f30da0e8d1ed1a7343. Options to fix already existing devices, which would only apply to Nexus devices with 4.3 or 4.4 at this point: 1) Add restorecon_recursive /data/misc/audio /data/misc/camera to either the system/core init.rc or to the device-specific init.*.rc files. -or- 2) Add a typealias declaration in the policy to remap the old type names. to the new ones. Then existing types on persistent storage will be remapped internally to the new ones. -or- 3) Some sort of relabeld. Option #2 is implemented by this change.

type app_data_file, file_type, data_file_type;
Label app data directories for system UID apps with a different type. We were using system_data_file for the /data/data directories of system UID apps to match the DAC ownership of system UID shared with other system files. However, we are seeing cases where files created in these directories must be writable by other apps, and we would like to avoid allowing write to system data files outside of these directories. So introduce a separate system_app_data_file type and assign it. This should also help protect against arbitrary writes by system UID apps to other system data directories. This resolves the following denial when cropping or taking a user photo for secondary users: avc: denied { write } for path="/data/data/com.android.settings/cache/TakeEditUserPhoto2.jpg" dev="mmcblk0p28" ino=82120 scontext=u:r:untrusted_app:s0 tcontext=u:object_r:system_data_file:s0 tclass=file avc: denied { write } for path="/data/data/com.android.settings/cache/CropEditUserPhoto.jpg" dev="mmcblk0p30" ino=602905 scontext=u:r:untrusted_app:s0 tcontext=u:object_r:system_data_file:s0 tclass=file Bug: 14604553 Change-Id: Ifa10e3283b07f6bd6ecc16eceeb663edfd756cea Signed-off-by: Stephen Smalley <sds@tycho.nsa.gov>

Get rid of separate platform_app_data_file type. The original concept was to allow separation between /data/data/<pkgdir> files of "platform" apps (signed by one of the four build keys) and untrusted apps. But we had to allow read/write to support passing of open files via Binder or local socket for compatibilty, and it seems that direct open by pathname is in fact used in Android as well, only passing the pathname via Binder or local socket. So there is no real benefit to keeping it as a separate type. Retain a type alias for platform_app_data_file to app_data_file until restorecon /data/data support is in place to provide compatibility.

Don't allow types which are both file_type and fs_type It's a bug to have a type with both the file_type and fs_type attribute. A type should be declared with either file_type, or fs_type, but not both. Create a neverallow rule which detects this situation. This works because we have the following allow rule: allow fs_type self:filesystem associate; If a type is a file_type and an fs_type, the associate allow rule will conflict with this neverallow rule.

# Should be:
# type apk_data_file, file_type, data_file_type;
Fix neverallow rules to eliminate CTS SELinuxTest warnings. Fix two neverallow rules that yield Invalid SELinux context warnings from the CTS SELinuxTest. For transitions from app domains, we only need to check { domain -appdomain } (i.e. domains other than app domains), not ~appdomain (i.e. all types other than app domains). Otherwise SELinuxTest tries to generate contexts with the r role and non-domain types for testing since the target class is process, and such contexts are invalid. For keeping file_type and fs_type exclusive, we only need to check associate permission, not all filesystem permissions, as only associate takes a file type as the source context. Otherwise SELinuxTest tries to generate contexts with the r role and non-domain types for testing filesystem permissions other than associate, since the source of such checks is normally a process context.
