Broken seteuid() call in official OOS13 due to missing kernel commits

[aviraxp]

When debugging system, I found that seteuid() call is completely broken. After some search, I found that it is kernel issue. This issue influences official ColorOS and OOS 13 with sm8250/sm8350.

Take sm8350_t_13.0.0_op9rt branch as an example. In the big commit Synchronize codes for OnePlus 9RT 5G MT2110_11_F.07/MT2111_11_F.07, upstream patch "binder: use euid from cred instead of using task" is picked, but the subsequent fix commit "binder: fix test regression due to sender_euidchange" is not. This causes caused some Android system test regressions, as described in the fix commit itself. This makes CTS like CredentialsTest#CaptureLayersTest test fail, and will cause more problems for end users. Same issue exists in SM8250 kernel too.

Solution is simple: pick "binder: fix test regression due to sender_euidchange" .

@OnePlusOSSAdmin Please deliver the issue to kernel developers. They know what I mean. Thx!

Thanks for your feedback. We’ll synchronize code with the latest version and this fix would be patched.
