Raw Normal View History

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.

restrict access to timing information in /proc These APIs expose sensitive information via timing side channels. This leaves access via the adb shell intact along with the current uses by dumpstate, init and system_server. The /proc/interrupts and /proc/stat files were covered in this paper: https://www.lightbluetouchpaper.org/2016/07/29/yet-another-android-side-channel/ The /proc/softirqs, /proc/timer_list and /proc/timer_stats files are also relevant. Access to /proc has been greatly restricted since then, with untrusted apps no longer having direct access to these, but stricter restrictions beyond that would be quite useful.

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.

restrict access to timing information in /proc These APIs expose sensitive information via timing side channels. This leaves access via the adb shell intact along with the current uses by dumpstate, init and system_server. The /proc/interrupts and /proc/stat files were covered in this paper: https://www.lightbluetouchpaper.org/2016/07/29/yet-another-android-side-channel/ The /proc/softirqs, /proc/timer_list and /proc/timer_stats files are also relevant. Access to /proc has been greatly restricted since then, with untrusted apps no longer having direct access to these, but stricter restrictions beyond that would be quite useful.

untrusted_app: allow access to /proc/tty/drivers /proc/tty/drivers is read by applications to figure out if they are running in an emulated environment. Specifically, they look for the string "goldfish" within that file. Arguably this is not an Android API, and really shouldn't be exposed to applications, but: 1) A largish number of applications break if they can't read this file; 2) The information here isn't particularly sensitive While we could spend a bunch of time trying to get applications fixed, there are bigger fish to fry. It's not worth the battle. Test: "ls -laZ /proc/tty/drivers" is labeled properly.

sepolicy: add support for new tracefs Since kernel 4.1 ftrace is supported as a new separate filesystem. It gets automatically mounted by the kernel under the old path /sys/kernel/debug/tracing. Because it lives now on a separate device some sepolicy rules need to be updated. This patch is doing that. Most of the rules are created based on a conversation happened on the SELinux Android mailing list: http://comments.gmane.org/gmane.comp.security.seandroid/2799 Note, that this also needs 3a343a1 from the 4.4 branch in kernel/common. Also note that when tracefs is auto mounted by the kernel, the kernel does not use the "mode" parameter specified to mount debugfs for tracefs. So an extra line like chmod 0755 /sys/kernel/debug/tracing is necessary in init.${ro.hardware}.rc after debugfs was mounted.
