fdsan crashes in Android 30 Apr 13, 2022 12:13:08 GMT

I have been plagued by many fdsan crashes during the Rhoconnect sync operation since upgrading to Android 30 SDK. I'm using the latest Rhodes 7.4 on the 7-4-stable branch.

The problem seems to be with blob (image files) and Rhoconnect.

I found the following in the fdsan documentation that may be relevant:

fdsan is a file descriptor sanitizer added to Android in API level 29. In API level 29, fdsan warns when it finds a bug. In API level 30, fdsan aborts when it finds a bug.

android.googlesource.com/platform/bionic/+/master/docs/fdsan.md

This may explain why the app is crashing with Android SDK 30 and was fine with Android SDK 29.

It is not possible to revert to Android SDK 29, because the minimum required targetSDK is 30.

Try this branch: github.com/rhomobile/rhodes/tree/android12_sdk31_ndk24
Update your SDK to latest, get platform 31, build tools 32.0.0, NDK v24, dont forget to set it in rhobuild.yml ( with rhodes-setup or manually )
We've checked rhoconnect sync with our test suite, no crashes/fdsan issues

config is

minSDK: 23
targetSDK: 31

Java 1.8 should work.

See your manifest, I suppose you use custom one. For default manifests changes were done, please refer
github.com/rhomobile/rhodes/commit/5811060654b3690ffe3d77b7c591e76c17698292#diff-782204668ea785d1a2df449749ead216caaf0d12a7d3238487b2b3d911e1a89aR50

How do I add the android:exported to com.rhomobile.rhodes.fcm.FCMIntentService?

I'm still experiencing the same crash. fdsan behavior can be reverted back to Android SDK 29 behavior with:

if (android_fdsan_set_error_level) {
android_fdsan_set_error_level(ANDROID_FDSAN_ERROR_LEVEL_WARN_ONCE);
}

stackoverflow.com/questions/69267194/android-11-jni-disable-fdsan

Where should I put this code in Rhodes source code to try to test if it helps my case?

I'd try to put it somewhere here:

github.com/rhomobile/rhodes/blob/master/platform/android/Rhodes/jni/src/fileapi.cpp#L616

Had no time to check it yet. Would appreciate if you can validate it on your end and make a PR if it works.

It is certainly more stable by disabling fdsan. The new warnings might help locate the true source of the issue:

It's difficult to reproduce and there are no exact steps:

1) Must use device. I cannot reproduce on emulator.

2) Use sync with a model with blobs (images 12+MP).

3) Sync many blobs from server (Download blobs from server seems to be the problem).

4) It seems that when a blob download fails, the sync retry has this fdsan error.

5) It also seems like performing an async net request during sync can trigger this problem.

6) Sometimes the crash is easy to reproduce, sometimes you have to try to sync a few times.

In my case was easy to reproduce;
while updating my VPN app (from Android v7 to Android v13),
I noticed that the VpnService's "fd" should NOT be closed manually,
and simply fixed it like:

```
int fd = ...;

#ifdef ANDROID
// For Android, closing VPN's TUN-device-fd causes:
// ```
// fdsan: attempted to close file descriptor 1,
// expected to be unowned, actually owned by unique_fd ...
// ```
#else
close(fd);
#endif
```
