* Remove old fork-and-specialize APIDave Platt2014-02-211-18/+1
| | | | | | | | | As promised, this is the cleanup patch-set which removes the old native "fork and specialize" API, which has been replaced by a slightly-enhanced one which can close the Zygote socket descriptors in the Zygote child. Change-Id: I33f504afd242e268863270139b4e421d4b0728f2
* Finish fixing Zygote descriptor leakage problemDave Platt2014-02-211-3/+76
| | | | | | | | | | | | | | | | | | In order to prevent Zygote descriptors from leaking into the child environment, they should be closed by the forked-off child process before the child switches to the application UID. These changes close the descriptors via dup2(), substituting a descriptor open to /dev/null in their place; this allows the Zygote Java code to close the FileDescriptor objects cleanly. This is a multi-project change: dalvik, art, libcore, frameworks/base, and external/sepolicy are affected. The CLs need to be approved together, lest the build break or the software fail to boot.

* | Zygote: Restrict slave mountspace so Dalvik apps can mount system-wide volumesMike Kasick2013-07-241-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Android 4.2 implements multi-user storage using per-process mount namespaces. Originally, everything under "/" (the entire filesystem hierarchy) is marked as a recursive-slave mountspace for all zygote instances. This is done so that user-storage sandbox mounts under /storage/emulated are hidden from other apps and users. Unfortunately this means that any Dalvik app (actually, any program whose clone/fork ancestry includes a Dalvik zygote, which is everything except services spawned directly from init) cannot mount system-wide volumes. Thus, apps like CifsManager are effectively broken in Android 4.2, since its cifs mounts are only visible to the CifsManager app itself. All other apps see empty mountpoints instead of the mounted volume. Furthermore, Linux provides no provision for a process to "escape" a recursive-slave mountspace in versions prior to Linux 3.8 (setns syscall). Here, we restrict the slave mountspace to /storage (and, due to a possible kernel bug, /mnt/shell/emulated) so that Dalvik apps can mount system-wide volumes elsewhere (with appropriate permission, as in earlier versions of Android), while retaining full multi-user storage compatibility. This change requires that a tmpfs volume is mounted as /storage in init.rc. If this volume is unavailable, then Zygote falls back to the previous behavior of marking the entire filesystem hierarchy as slave. It also implicitly requires that EMULATED_STORAGE_TARGET is path-prefixed by (part of the subhierarchy of) ANDROID_STORAGE, which is the typical case.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Be sure to add '#define MADV_MERGEABLE 12' to bionic/libc/include/sys/mman.h so we can have a central place for this parse the process memory map and inform madvise common HEAP/Stack regions on fork from zygote These then can be used by the kernel KSM module to re-join (copy on write) pages between the various dalvik processes. As is on a fully loaded system you can expect ~12MB to be indicated to be scanned by KSM.. of this 10-15% will be saved; as such a recommend a very slow scan until as any logic to stop scanning while sleeping will require another process and remove all memory savings provided by this logic. To activate on a KSM kernel (2min for full scan of ~16m and 1%CPU): echo 4000 > /sys/kernel/mm/ksm/sleep_millisecs echo 128 > /sys/kernel/mm/ksm/pages_to_scan echo 1 > /sys/kernel/mm/ksm/run Newer kernels only require the last line. In future additional memory regions and kernel logic may improve this. Change-Id: I271cbee74a1f02a89c34c6ee9006a4ea81360154

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prevent a zygote spawned application from acquiring capabilities other than CAP_NET_RAW. The only Zygote accessible program on Android which grants capabilities is /system/bin/ping (CAP_NET_RAW), so we don't need to keep the other capabilities in our bounding set. If the kernel doesn't support file capabilities, we end up printing approx 30 lines of warning messages. Hopefully this will encourage kernel developers to upgrade. In a future change, we can turn a prctl(PR_CAPBSET_DROP) failure into a fatal error. Change-Id: I8560fa5ad125bf31f0d13be513431697bc7d22bb
