Phones reboot with Syncthing 1.30 under LineageOS 16 on HTC m8

kisenberg · October 2, 2019, 6:51am

I did a clear install of LineageOS 16 on an HTC m8 and Syncthing 1.2.2. Everythings run fine. Yesterday, Google Play Store updates Syncthing to 1.30. After few minutes later my phone reboots by itself. After it came up again and maybe 30 seconds later, the phone did reboot again. This happend until I managed to disable Syncthing. Also the phone got hot.

I have another HTC m8 to install and did also a clear install of LineageOs 16. I also installed Syncthing 1.30 from Play Store. A few seconds after starting Syncthing and granted all necessary rights, Syncthing began to create its key and the phone rebooted by itself.

Maybe with release of version 1.30, there seems to be somethong wrong. Two working and clean installed phones get in boot loop after Syncthing 1.3 was installed. Version 1.2.2 works fine on it.

No app should be able to force a phone to reboot. Sure, syncthing probably does some scanning which uses a lot of cpu which makes the phone hot, but that should not be enough to force the phone to reboot.

Sadly nothing important changed in syncthing for this to happen, best I can suggest is to see if the logs (both phone and syncthing) have any hints.

I am having the same issue on my OnePlus One running custom DirtyUnicorns 12 ROM based on Android Oreo. Opening the Syncthing app reboots the phone to bootlogo. I can confirm that it was working well before the last update. Is it somehow related to this: https://github.com/syncthing/syncthing-android/issues/1001 ? Unfortunately I don’t have access to my phone now. Will post the logs as soon as I get my phone back.

After putting one of the phones into the fridge for an hour, I tried to start Syncthing with deleted data and cache. There seems to be no overheating, cause the phone rebooted after nearly the same time. A resart of Syncthing leads me directly to the log. The syncthing log is empty. The Android log shows: --------- beginning of main 10-02 20:34:30.287 E/libEGL ( 7525): error mmaping cache file: Invalid argument (22) 10-02 20:34:30.309 I/SyncthingService( 7525): shouldRun decision changed to true according to configured run conditions. 10-02 20:34:30.310 I/SyncthingService( 7525): Shutting down background service 10-02 20:34:30.334 W/ConfigXml( 7525): Cannot read ‘/data/user/0/com.nutomic.syncthingandroid/files/config.xml’ 10-02 20:34:30.334 W/ConfigXml( 7525): org.xml.sax.SAXParseException: Unexpected end of document 10-02 20:34:30.334 W/ConfigXml( 7525): at org.apache.harmony.xml.parsers.DocumentBuilderImpl.parse(DocumentBuilderImpl.java:125) 10-02 20:34:30.334 W/ConfigXml( 7525): at javax.xml.parsers.DocumentBuilder.parse(DocumentBuilder.java:183) 10-02 20:34:30.334 W/ConfigXml( 7525): at com.nutomic.syncthingandroid.util.ConfigXml.readConfig(ConfigXml.java:100) 10-02 20:34:30.334 W/ConfigXml( 7525): at com.nutomic.syncthingandroid.util.ConfigXml.(ConfigXml.java:72) 10-02 20:34:30.334 W/ConfigXml( 7525): at com.nutomic.syncthingandroid.service.SyncthingService$StartupTask.doInBackground(SyncthingService.java:354) 10-02 20:34:30.334 W/ConfigXml( 7525): at com.nutomic.syncthingandroid.service.SyncthingService$StartupTask.doInBackground(SyncthingService.java:339) 10-02 20:34:30.334 W/ConfigXml( 7525): at android.os.AsyncTask$2.call(AsyncTask.java:333) 10-02 20:34:30.334 W/ConfigXml( 7525): at java.util.concurrent.FutureTask.run(FutureTask.java:266) 10-02 20:34:30.334 W/ConfigXml( 7525): at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1167) 10-02 20:34:30.334 W/ConfigXml( 7525): at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:641) 10-02 20:34:30.334 W/ConfigXml( 7525): at java.lang.Thread.run(Thread.java:764) 10-02 20:34:30.365 I/Adreno-EGL( 7525): <qeglDrvAPI_eglInitialize:379>: EGL 1.4 QUALCOMM build: Nondeterministic_AU_msm8974_LA.BF.1.1.3_RB1__release_AU (I741a3d36ca) 10-02 20:34:30.365 I/Adreno-EGL( 7525): OpenGL ES Shader Compiler Version: E031.29.00.00 10-02 20:34:30.365 I/Adreno-EGL( 7525): Build Date: 04/04/16 Mon 10-02 20:34:30.365 I/Adreno-EGL( 7525): Local Branch: mybranch19053788 10-02 20:34:30.365 I/Adreno-EGL( 7525): Remote Branch: quic/LA.BF.1.1.3_rb1.12 10-02 20:34:30.365 I/Adreno-EGL( 7525): Local Patches: NONE 10-02 20:34:30.365 I/Adreno-EGL( 7525): Reconstruct Branch: NOTHING 10-02 20:34:30.373 I/ConfigStore( 7525): android::hardware::configstore::V1_0::ISurfaceFlingerConfigs::hasWideColorDisplay retrieved: 0 10-02 20:34:30.373 I/ConfigStore( 7525): android::hardware::configstore::V1_0::ISurfaceFlingerConfigs::hasHDRDisplay retrieved: 0 10-02 20:34:30.373 I/OpenGLRenderer( 7525): Initialized EGL, version 1.4 10-02 20:34:30.380 W/Adreno-EGL( 7525): <qeglDrvAPI_eglGetConfigAttrib:607>: EGL_BAD_ATTRIBUTE 10-02 20:34:30.389 W/Adreno-EGL( 7525): <qeglDrvAPI_eglGetConfigAttrib:607>: EGL_BAD_ATTRIBUTE 10-02 20:34:30.476 E/libEGL ( 7525): error mmaping cache file: Invalid argument (22) 10-02 20:34:38.842 W/ActivityThread( 7525): handleWindowVisibility: no activity for token android.os.BinderProxy@1c384a1 10-02 20:34:38.926 W/Adreno-EGL( 7525): <qeglDrvAPI_eglGetConfigAttrib:607>: EGL_BAD_ATTRIBUTE 10-02 20:34:40.992 W/Adreno-EGL( 7525): <qeglDrvAPI_eglGetConfigAttrib:607>: EGL_BAD_ATTRIBUTE

AudriusButkevicius · October 2, 2019, 7:25pm

That still shouldn’t reboot the phone.

Catfriend1 · October 2, 2019, 9:08pm

I am also clueless what causes a reboot here … :-/

kisenberg · October 3, 2019, 6:52am

Clean install of LineageOS 16, several clean install of Syncthing 1.30 (also with cleared data and cache), also update from running 1.2.2 or clean install of Syncthing 1.3 with imported config; all the same behavior: both phones(!) reboot. No problem with 1.2.2. Was there a change in libraries or version of software components from 1.2.2 to 1.30? I’m clueless.

It’s a great work from the maintainer. I love the tool. It would be a pain not to use it anymore.

AudriusButkevicius · October 5, 2019, 2:18pm

Nothing has changed in that area. We are building with new go that could cause this I guess.

AudriusButkevicius · October 5, 2019, 3:25pm

that’s the changes. You can try doing a git bisect, to figure out which commit causes it.

AudriusButkevicius · October 5, 2019, 5:10pm

Quic was there before 1.3

khumarahn · October 7, 2019, 9:41pm

Just to say, I have the same with Zuk Z1 on Lineageos 16.0. I opened an issue on github, but Audrius closed it and pointed me here.

How do you downgrade? An attempt to downgrade with f-droid gives “unknown error”.

Don’t want to reinstall the app, because then I need to configure everything again.

khumarahn · October 8, 2019, 10:47am

How do I disable the nat checkbox? I start syncthing and the phone reboots, I can’t do anything.

neden · October 8, 2019, 2:04pm

@Catfriend1 Is there a way to disable NAT, without running the synchronization?

kisenberg · October 8, 2019, 3:47pm

I didn’t downgrade. Fortunately one day before, I did a clean install of one of the phones. So I made a backup of the settings, installed the phone, installed Synchting 1.2.2 and all went well. The next day, I wanted to hand over the new installed phone and I saw an information about an update to syncthing 1.30. After the update, well, you know the story.

So I uninstalled 1.30, installed 1.2.2.4 from F-Droid and was able to restore my backup. If you rooted your phone, you may try to get your config from /data/data/com.nutomic.syncthingandroid/

kisenberg · October 8, 2019, 3:55pm

With root access to your phone you can edit /data/data/com.nutomic.syncthingandroid/files/config.xml. Under you will find true. Replace true with false, save the config.xml and restart syncthing or better reboot your phone.

I think it is caused by a kernel bug:

The flash storage in my ageing HTC One M7 was quite badly worn and sometimes, when Syncthing’ing or copying a lot of data, the phone would spontaneously reboot. After setting the rate limits to 4.5MBps (incl. on LAN) the reboots ceased. I figured this was a hardware watchdog of some sort. It was reliably only happening when I synced / copied 200MB+ of data continuously. Just thought I’d chime in with a data point.
