+## fdtrack
+
+fdtrack consists of two parts: a set of hooks in bionic to register a callback
+that's invoked on file descriptor operations, and a library that implements a
+hook to perform and store backtraces for file descriptor creation.
+
+### bionic hooks
+bionic provides a header in the `bionic_libc_platform_headers` header_lib at <[bionic/fdtrack.h](https://android.googlesource.com/platform/bionic/+/refs/heads/master/libc/platform/bionic/fdtrack.h)>.
+Register a callback with `android_fdtrack_compare_exchange_hook` to receive
+callbacks upon file descriptor creation and destruction. This function can be
+called at any point in order to start capturing events, but be sure to properly
+handle unbalanced closes. This callback may be called from an async signal safe
+context, but not vfork (bionic tracks whether a thread is vforked, and chooses
+not to call callbacks when this is the case).
+
+### libfdtrack
+[libfdtrack](https://android.googlesource.com/platform/bionic/+/refs/heads/master/libfdtrack)
+implements a library that uses libunwindstack to unwind and store fd creation backtraces.
+
+
+#### Using libfdtrack
+libfdtrack registers its hook upon being loaded, so to start capturing
+backtraces, `dlopen("libfdtrack.so", RTLD_GLOBAL)` is all that's needed. To dump
+its output to logcat, either use `fdtrack_dump`, or send the signal
+`BIONIC_SIGNAL_FDTRACK` (available from `<bionic/reserved_signals.h>`) to the
+process. If you wish to iterate through the results programmatically,
+`fdtrack_iterate` can be used (warning: this interface is currently unstable,
+don't use it in code that can be used on multiple platform versions.)
+
+libfdtrack adds a significant amount of overhead, so for processes that are
+latency-critical like system_server, it's not feasible to always capture
+backtraces. Instead, if you can detect that an fd leak is ongoing, turning on
+backtraces for a while and then triggering a dump can be sufficient.
+system_server [implements this approach](https://android.googlesource.com/platform/frameworks/base/+/679f3e4242b8e018eb7df90ef433f81088a64fff%5E%21/),
+spawning a thread that regularly checks the count of fds in the process, turns
+on fdtrack when it hits a threshold, and then aborts after another threshold.
+This dumps the output to logcat, which will be available in both the tombstone
+and logcat from bugreports.
+
+#### Implementation details
+There are multiple methods to unwind in Android:
+
+ * libunwindstack
+ * Pros
+ * Primary method on the platform
+ * Able to unwind through ART
+ * Cons
+ * Uses malloc internally: unsafe unless a separate allocator is
+ statically-linked and steps are taken to prevent the unwind from being
+ interrupted by a signal
+ * Slow - infeasible to be used always in latency-sensitive processes
+ * `android_unsafe_frame_pointer_chase`
+ * Pros
+ * Definitely async signal safe
+ * Fast
+ * Cons
+ * Unable to unwind through ART because it doesn't maintain the frame pointer
+ * Requires -fno-omit-frame-pointer to be used on all code being unwound
+ through, which currently isn't the case on Android
+ * Frame layout is a mess on 32-bit ARM: the ARM standard, clang, and GCC
+ [all disagree](https://gcc.gnu.org/bugzilla/show_bug.cgi?id=92172)
+ * Chasing the frame pointer will often result in multiple frames inside the
+ same function
+
+libfdtrack chooses to use libunwindstack for now, since unwinding through ART
+is critical to being useful for the initial user, system_server.

+ * `__ANDROID_API__` is the [API
+ * level](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
+ * this code is being built for. The resulting binaries are only guaranteed to
+ * be compatible with devices which have an API level greater than or equal to
+ * `__ANDROID_API__`.
+ *
+ * For NDK and APEX builds, this macro will always be defined. It is set
+ * automatically by Clang using the version suffix that is a part of the target
+ * name. For example, `__ANDROID_API__` will be 24 when Clang is given the
+ * argument `-target aarch64-linux-android24`.
+ *
+ * For non-APEX OS code, this defaults to __ANDROID_API_FUTURE__.
+ *
+ * The value of `__ANDROID_API__` can be compared to the named constants in
+ * `<android/api-level.h>`.
+ *
+ * The interpretation of `__ANDROID_API__` is similar to the AndroidManifest.xml
+ * `minSdkVersion`. In most cases `__ANDROID_API__` will be identical to
+ * `minSdkVersion`, but as it is a build time constant it is possible for
+ * library code to use a different value than the app it will be included in.
+ * When libraries and applications build for different API levels, the
+ * `minSdkVersion` of the application must be at least as high as the highest
+ * API level used by any of its libraries which are loaded unconditionally.
+ *
+ * Note that in some cases the resulting binaries may load successfully on
+ * devices with an older API level. That behavior should not be relied upon,
+ * even if you are careful to avoid using new APIs, as the toolchain may make
+ * use of new features by default. For example, additional FORTIFY features may
+ * implicitly make use of new APIs, SysV hashes may be omitted in favor of GNU
+ * hashes to improve library load times, or relocation packing may be enabled to
+ * reduce binary size.
