Steven Moreland ee22384c54 libutils: check vsnprintf error
For encoding errors, this function will return a negative value which
causes problems down the line. Check for an error and return. Also,
integer overflows are guarded.

Christopher Ferris 4d14303653 Fail explicitly on length overflow.
Instead of aborting when FileMap::create detects an overflow, detect the
overflow directly and fail the call.

Bug: 156997193

Test: Ran unit tests, including new unit test that aborted before.

Adam Vartanian 47efc676c8 Fix integer overflow in utf{16,32}_to_utf8_length
Without an explicit check, the return value can wrap around and return
a value that is far too small to hold the data from the resulting
conversion.

No CTS test is provided because it would need to allocate at least
SSIZE_MAX / 2 bytes of UTF-16 data, which is unreasonable on 64-bit
devices.

Justin Yun aeb68e86e4 Mark the modules as VNDK-SP in Android.bp
As a VNDK-SP module, Android.bp must have 'vndk' tag as well as
'vendor_available: true'.

The 'vndk' tag for VNDK-SP formated as follows:
vndk: {
    enabled: true,
    support_system_process: true,
},

VNDK-SP modules will be installed both in system/lib(64) as normal
and in system/lib(64)/vndk-sp as a vendor variant.

Jiyong Park 0b3c24bd4f fix: ATRACE does not work for libs loaded in sphal namespace
From O, libutils.so is loaded twice. Once in the default namespace and
once in the sphal namespace for vendor libs. However, since the
framework only communicates with the instance loaded in the default
namespace, report_sysprop_change() event is not notified to the instance
in sphal namespace. This causes ATRACE to not work for vendor libs
loaded in sphal namespace.

So, the instance loaded in default namespace now explicitly redirects
the event to the other instance.

Test: start an app, run 'adb shell atrace gfx --stream'. atrace from the

Renaud Paquay b7a4f0b9e2 Fix uninitialized member variable
The default constructor of FileMap was missing an initializer for the
mFileMapping variables. This results in CloseHandle being called with
a "random" value, which can cause havoc in Win32 process over time (e.g.
in the case of libaapt2_jni.dll, which is loaded in a JVM process).

Also, update the code to use "NULL" for invalid file map handle
and "INVALID_HANDLE_VALUE" for invalid file handle.

Also added some items into windows-deprecated.h. This file is supposed

including libsystem_headers adds system headers before libnativewindow

Steven Moreland 91527edec8 libutils: mark as vendor_available
By setting vendor_available, the following may become true:

* a prebuilt library from this release may be used at runtime by
  in a later releasse (by vendor code compiled against this release).
  so this library shouldn't depend on runtime state that may change
  in the future.
* this library may be loaded twice into a single process (potentially
  an old version and a newer version). The symbols will be isolated
  using linker namespaces, but this may break assumptions about 1
  library in 1 process (your singletons will run twice).

Background:

This means that these modules may be built and installed twice --
once for the system partition and once for the vendor partition. The
system version will build just like today, and will be used by the
framework components on /system. The vendor version will build
against a reduced set of exports and libraries -- similar to, but
separate from, the NDK. This means that all your dependencies must
also mark vendor_available.

At runtime, /system binaries will load libraries from /system/lib*,
while /vendor binaries will load libraries from /vendor/lib*. There
are some exceptions in both directions -- bionic(libc,etc) and liblog
are always loaded from /system. And SP-HALs (OpenGL, etc) may load
/vendor code into /system processes, but the dependencies of those
libraries will load from /vendor until it reaches a library that's
always on /system. In the SP-HAL case, if both framework and vendor
libraries depend on a library of the same name, both versions will be
loaded, but they will be isolated from each other.

It's possible to compile differently -- reducing your source files,
exporting different include directories, etc. For details see:

https://android-review.googlesource.com/368372

None of this is enabled unless the device opts into the system/vendor
split with BOARD_VNDK_VERSION := current.

Mark Salyzyn 0484b3b575 logd: ASAN cleansing
A mixture of fixes and cleanup for LogKlog.cpp and friends.

- sscanf calls strlen.  Check if the string is missing a nul
  terminator, if it is, do not call sscanf.
- replace NULL with nullptr for stronger typechecking.
- pass by reference for simpler code.
- Use ssize_t where possible to check for negative values.
- fix FastCmp to add some validity checking since ASAN reports that
  callers are not making sure pre-conditions are met.
- add fasticmp templates for completeness.
- if the buffer is too small to contain a meaningful time, do not
  call down to log_time::strptime() because it does not limit its
  accesses to the buffer boundaries, instead stopping at a
  terminating nul or invalid match.
- move strnstr to LogUtils.h, drop size checking of needle and
  clearly report the list of needles used with android::strnstr
- replace 'sizeof(static const char[]) - 1' with strlen.

Test: gTest liblog-unit-test, logd-unit-tests & logcat-unit-tests
