Firebase phone auth doesn't work on lineageos

Asked 2021-Jun-02 at 06:14

I'm working on a capacitor app that uses capacitor-firebase-auth for phone auth using firebase. The app now has thousands of users and for the vast majority everything works fine. However, a few users per day are not able to login with phone number, and most of them are using a custom ROM like lineageos.

In order to debug the problem, I installed lineageos on one of my devices. Logcat of login with phone number looks like this:

Answered 2021-Jun-02 at 06:14

ok, I found the solution: for some reason, google-services.json did not include my play store signing SHA1 key, despite it being present in firebase admin console. Solution: I removed the SHA1 key and added it again... Afterwards, google-services.json included my release SHA1 and phone auth works even on lineageos.

Apparently SHA256 is required for phone verification using safetynet which works on standard androids, and SHA1 is only required for the recaptcha flow which is required on non-standard androids. This explains why it worked for the vast majority of users.

Two things:

You must do a POST request (currently you are doing a get request)

You are not including the body of the request. For example, the curl call includes url encoded data like this: data-urlencode 'q=Hallo'. You must include this parameters in your post request too, the provided link shows you how. This are key values that will go inside a dictionary, for example {q: 'Hallo', ...}

PS: I'm 90% sure that you should also convert to a dictionary the query params you currently have inside tuples. So, you'd have post with headers, params and data.

USB: why USB devices the modules automatically loaded

As you can see in the dmesg output:

[ 5.379690] usb 1-1: New USB device found, idVendor=10c4, idProduct=ea60

Looking that up, e.g. here: https://www.google.com/search?q=usb%20vendor%20id%2010c4

Tells you that it's a "Silicon Labs" USB device, who also make the CP2102.

The log does not identify other devices (ignore the linux kernel root hub). So either you have also a CP2102 attached (and the FTDI is not properly connected) or the device you think is a FTDI based device, is not.

In addition you can identify currently enumerated devices using the lsusb command.

The automatic loading is usually done by udev or a similar user space daemon/mechanism. A decent explanation can be found e.g. here: https://lwn.net/Articles/740455/

QUESTION

Access point doesn't start with Raspberry Pi 3 built-in Wi-Fi

Asked 2019-Nov-03 at 18:17

I have Raspberry Pi 3 and I use it as a Wi-Fi access point. I use Raspberry Pi 3 built-in Wi-Fi adapter for this.

Until today, the access point worked.

Today it stopped working. I think that Raspberry Pi crashed and I then turn the power off without shutting it down. Since then, it doesn't work.

If I run it as service, the status will show running (exited).

When I run it with sudo /usr/sbin/hostapd -dd /etc/hostapd/hostapd.conf, I get the following errors and it doesn't work:

Answered 2019-Feb-22 at 20:06

Access point started working now, but I didn't change anything. Maybe there were some corrupted files, but the system repaired them after a few reboots.

I also got answers on Raspberry Pi Forums by epoch1970. I don't know if they would fix the problem, but they are mostly about corrupted files, so they probably fix the problems.

g++ link library x.so.2 without absolute path

Asked 2019-Jul-23 at 13:01

This is an old qustion, but i still can not find the solution.

i have library: /usr/lib/x86_64-linux-gnu/libqca.so.2 (it is installed by package libqca2, and packager did not provide libqca.so link, nor I want to do that because i am looking for answer on all similar situations, not for qca example only)

so how can i include it without providing lib full-path-name:

g++ -L/usr/lib/x86_64-linux-gnu -lqca will not work because of .2 extension
g++ -L/usr/lib/x86_64-linux-gnu -lqca.so.2 is not allowed
g++ -L/usr/lib/x86_64-linux-gnu qca.so.2 not working too.

so seems as simple question, what is the answer.

"NO IT CAN NOT" can be the correct answer if someone with gcc/g++ knowledge can say it 100% and describe something about it... but isn't it strange that gcc has both infomations (paths to look for, and correct lib name) and can not just combine it (like it does with -l param for libs with standard naming).

Ok, I found the ANSWER my self,

it is about COLON character,

-l:libqca.so.2

answer found here on linux manuals: -l namespec ... If namespec is of the form :filename, ld will search the library path for a file called filename, otherwise it will search the library path for a file called libnamespec.a
