2023-07-14Properly handle unsetting of overrideFlorian Mayer
When the override went from force_on -> default, we would keep the memtag setting on, even if the user hadn't manually turned it on. Bug: 291106070 Test: atest mtectrl_test Change-Id: I67e357d20e1c8ce2608b92a55e7b3d295b9ea87d

2023-05-01[MTE] Bootloader override enables permissive mode.Evgenii Stepanov
Move droidfood/dogfood users on the mte bootloader override experiment to permissive MTE mode to reduce the reliability impact while still collecting crash reports and perf/power data.

2022-11-04Initialize arm64.memtag.bootctl in early-initFlorian Mayer
Now it actually runs before adbd starts. Also no longer sync back the force override into the property. That ended up causing more trouble than it's worth, it's okay to wait for next reboot for that to happen. Any UI needs to check the override separately anyway to properly display to the user. Test: multiple runs of `atest mtectrl_end_to_end_test` from https://r.android.com/2272571 Change-Id: I179ac0ef5540e183aa1ddd59d2d6b2fe84b5c591

2022-10-28[mtectrl] resolve race with rebootFlorian Mayer
without this change, setprop "arm64.memtag.bootctl" [...] && reboot was racy, because it was not guaranteed that the change was applied before rebooting. we still immediately apply the changes as well, just in case there is a thermal shutdown, which does not run triggers.
