Hi Greg,

Hi Nathan,

I am so sorry I didn't catch this in my initial report but this commit along with ba7aaf93ef2f ("netlink: Don't shift with UB on nlk-

...

ngroups")

breaks mobile data on both the Pixel 2 XL and OnePlus 6. There is signal but it just never connects to 3G/LTE. Reverting those two commits fixes the issue.

Sorry for breaking your use-case,

Nothing stands out to me in dmesg unfortunately and iven neither device is running a vanilla kernel, I cannot say if this is a problem in mainline or not but I just wanted to make you aware of it.

Could you provide the dmesg output for the attached debug diff?
