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.

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.

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.

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.

Policy covers: * backup_data_file type for labeling all files/dirs under /data dealing with backup mechanism. * cache_backup_file type for labeling all files/dirs under /cache dealing with backup mechanism. This also covers the the use of LocalTransport for local archive and restore testing. * the use of 'adb shell bmgr' to initiate backup mechanism from shell. * the use of 'adb backup/restore' to archive and restore the device's data.

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. Not sure if this is the cleanest way to accomplish this, but it seems to work. Change-Id: Ida387b1df260efca15de38ae7a66ed25e353acaa

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.
