* Allow debugging only for apps forked from zygoteSebastien Hertz2015-08-101-2/+2
| | | | | | | | | | When starting the runtime from app_process, we only pass JDWP options if starting zygote. It prevents from opening a JDWP connection in non-zygote programs while Android apps (forked from zygote) remain debuggable. Bug: 23050463 Change-Id: If8ea719063a65db4cdeed69a838b52e87b078b08
* Add libwilhelm to app_process.Christopher Ferris2015-06-171-2/+11
| | | | | | | | | | | | | | | If an app exposes new/delete from a shared library, the libwilhelm shared library can wind up using the new from the app shared library, and the delete from libc++. It is completely legal for the app to export new/delete in this way, so in order to avoid this situation, preload libwilhelm in the zygote. This forces libwilhelm to always resolve the new/delete from libc++. This library cannot be added to android_runtime since libwilhelm has a shared library which depends on android_runtime.

* Better systrace slices for application startup.Narayan Kamath2015-06-161-3/+0
| | | | | | | | | | | | | | | | | | | | | | | This change adds three new timeslices : - PostFork : As soon as possible after the app forks from the zygote. Can be used in conjunction with the system_server "Start proc:" event to derive an upper bound on fork() and zygote overhead. - RuntimeInit & ActivityThreadMain for ZygoteInit#runtimeInit and ActivityThread#main. ActivityThread#handleBindApplication and higher level functions are already well instrumented in systrace. handleBindApplication should occur immediately after ActivityThread#main. Note that we use the Activity manager tag to make it easier to correlate these new events with surrounding events (Start proc and handleBindApplication) that are already using the AM tag. bug: 21632700 Change-Id: Ibc01f1721f962c913f3c02a51763b6feb1eb6a4d

* app_main missing include for sys/stat.hMark Salyzyn2015-04-011-5/+6
| | | | | | | | | | | | app_main.c gets sys/stat.h inherited from private/android_filesystem_config.h it should not rely on this in the future. The intent is to move fs_config function into libcutils and thus deprecate any need for sys/stat.h in this include file. Bug: 19908228 Change-Id: I477b825e582742113f849aaa1df50c41e496b6f6

* | Clean entire arg block when setting process name.Jeff Brown2014-09-111-9/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When Android processes fork from Zygote, we rewrite the command line with a new name, eg. "system_server". When we do this, we should fill the entire block with zeros to remove corrupted argument information that may otherwise remain in the /proc/<pid>/cmdline buffer and be seen in tools and stack dumps. Fixed an issue where VM options could be overwritten after setting the nice name if the name was too long. Bug: 17474152 Change-Id: Ie6cf9ed7752a04300a340e26cd6812bb35c59e1b

* app_process: change app_process a symlink of primary versionYongqin Liu2014-05-141-2/+5
| | | | | | | | | | | | | Change app_process to be a symlink to the primary version and have app_process32/app_process64 be the 32-bit/64-bit versions respectively. This will make it possible to use the primary zygote for am/pm commands and other scripts that use app_process and don't need a specific zygote.

* Create arch specific cache dirs during zygote startup.Narayan Kamath2014-05-011-0/+42
| | | | | | | | | | The runtime expects them to exist before it's launched. The boot image / art files are created during the first zygote launch. (cherry picked from commit da738713e4e2120a324e8ab6fd11aa0e54a3c66e) Change-Id: I7472aa25c16a1cf95791af2bdf80ed0d73123872
* Set NO_NEW_PRIVS on zygote initNick Kralevich2014-04-291-0/+10
| | | | | | | | | | | | When app_process/zygote starts, make sure PR_SET_NO_NEW_PRIVS is set. This prevents zygote spawned apps from acquiring new privileges on exec. In particular, this allows the CTS test android.os.cts.SecurityFeaturesTest#testNoNewPrivs() to pass if ART is set as the default runtime. Change-Id: I81139cda999c7b1430242561aad28f566e9b6da0

* Don't compare String8s to NULL.Narayan Kamath2014-04-121-1/+1
| | | | | | | | Use String8::isEmpty instead. Note that this code path is hit only if the zygote calls ::exit, and that never happens unless the VM invocation fails. Change-Id: I0e7d3a86a79b12b2174ca3bf0dbe1904e33c041a

* Clean up argc / argv processing for runtime args.Narayan Kamath2014-04-091-40/+59
| | | | | | | | | | | | - Make copies of argc, argv before argv is potentially overwritten with the process name. - Allow multiple command line arguments to be passed to ZygoteInit (this is required for some of the 64 bit zygote work). - Add an explanatory comment about how these argments are processed.

Process:setArgV0 was being called by android.util.Process, but that functionality can be moved directly into the implementation of that class. bug: 13647418 Change-Id: I216c8f8a4c065f0cf3a61f19f9e32decd26f93f6
* app_process: use LOCAL_MULTILIB := bothColin Cross2014-03-271-22/+3
| | | | | | | | | | | Use LOCAL_MULTILIB := both to build app_process64 instead of duplicating the build rule. Also causes PRODUCT_PACKAGES := app_process to install both versions on 64-bit platforms, as the module names for both app_process and app_process64 are now app_process.

* revert ADDR_COMPAT_LAYOUT workaround.Nick Kralevich2013-09-181-29/+0
| | | | | | | | | | | | | Stop working around bad applications by setting ADDR_COMPAT_LAYOUT. ADDR_COMPAT_LAYOUT is undesirable because it reduces the amount of address space available to an application. The Android emulator, in both 4.3 and 4.4, does not set ADDR_COMPAT_LAYOUT. Anyone needing to test their application on a version of Android without ADDR_COMPAT_LAYOUT can use the emulator and reproduce the failures. Change-Id: I8f753acc205798bd7f031026c7ece12d26de562c

| | | | | | | | | | | | | | | | | | This change disables all atrace tracing in Zygote immediately after it is initialized. This is necessary because Zygote has no way to receive notifications that the enabled trace tags have been changed. Tracing is re-enabled when other processes fork from Zygote.

* Never call app_main more than onceNick Kralevich2013-03-151-4/+3
| | | | | | | | | | | | Different kernels seem to handle ADDR_COMPAT_LAYOUT differently, sometimes passing it to its children, sometimes not. If it's not passed to its child successfully, we can end up in a restart loop. Instead of testing for the presence of ADDR_COMPAT_LAYOUT, use an environment variable instead, which is handled more predictably. Bug: 8392487 Change-Id: Ia531dd2abb4e1cd46f3430d844e644f53581f530
* Don't use ADDR_COMPAT_LAYOUT on the emulatorNick Kralevich2013-03-141-5/+10
| | | | | | | | | | | | | For the emulator, we want people to see memory as it actually is, not how we're hacking around buggy apps. Don't set ADDR_COMPAT_LAYOUT on the emulator. For reasons that I don't understand, personality(ADDR_COMPAT_LAYOUT) does not persist across an exec on the emulator. app_main gets into a tight loop restarting itself because of this. This change also works around that bug. Change-Id: Ia73a7d2d623c25cf39d248145d97307945d554da
