A couple bugs were mentioned on IRC that might have affected this: https://bugzil.la/1291424 — FIXED, esawin@mozilla.com — Consider removing on-demand decompression linker https://bugzil.la/1298090 — FIXED, esawin@mozilla.com — Extract shared libraries on APK update I'm marking this critical because it affects preload distributions.

Looks like esawin is actually the one I should ni?

Yeah, those are the likely bugs. I see one interesting thing: 05-12 01:17:20.421 2217 2217 W Gecko : type=1400 audit(0.0:30): avc: denied { execute } for path="/data/data/org.mozilla.fennec_aurora/cache/libnss3.so" dev="mmcblk0p28" ino=81590 scontext=u:r:platform_app:s0:c512,c768 tcontext=u:object_r:app_data_file:s0:c512,c768 tclass=file permissive=0 It looks like selinux is preventing us from mapping the library as executable. Before, we would've been doing this with anonymous memory and not a specific file. I don't see this message when launching Fennec with a normal install, so I think this may be where things are going south. Fabrice, maybe see about tweaking the selinux config? 09-06 00:41:21.975 2202 2217 E GeckoLinker: /system/app/B2G/B2G.apk!/assets/armeabi-v7a/libnss3.so: Failed to mmap The path there is wrong, but I think that's just a busted error message? The message above indicates that we probably tried to open the right path.
Fabrice, I'm looking at the platform_app policy here[0] and it seems pretty restrictive compared to what I think is the 'normal' app policy at [1]. Maybe you can try launching Fennec differently? How are you starting it now? [0] http://androidxref.com/7.0.0_r1/xref/system/sepolicy/platform_app.te [1] http://androidxref.com/7.0.0_r1/xref/system/sepolicy/app.te
Flags: needinfo?(snorp) → needinfo?(fabrice)
I'm starting it with |am start org.mozilla.xxx| You're right about the selinux configuration. I tested by changing the LOCAL_CERTIFICATE in the build config to "shared" instead of "platform" and that let us start. Obviously I'll have to check what the consequences are, but for my own experiment it's good enough!

The relevant change happened in bug 1291424. > 09-06 00:41:21.868 2202 2202 W System : ClassLoader referenced unknown > path: /system/app/B2G/lib/arm > 09-06 00:41:21.975 2202 2217 E GeckoLinker: > /system/app/B2G/B2G.apk!/assets/armeabi-v7a/libnss3.so: Failed to mmap These logs are worrying. Does changing the selinux config fix the package path? The package path is passed down to the linker from here: https://dxr.mozilla.org/mozilla-central/source/mobile/android/geckoview/src/main/java/org/mozilla/gecko/GeckoThread.java#395

Using a releasekey fixes the issue too. I would be surprised if partners needed anything else, so if no one objects I think we can close this bug.
