2021-11-17Add empty static user-mode helper pathTodd Frederick
To pass CtsSecurityHostTestCases, the static user-mode helper must be enabled, and it must be set to an approved path. The default path, /sbin/usermode-helper, is not approved and does not exist on this platform. A blank string disables user-mode helpers entirely when static user-mode helper support is enabled, which is also acceptable.

2021-06-14Increase kernel log buffer sizeTim Kryger
Under the v4.9 kernel, the log size was set this to 2^20 = 1 MiB but, as part of the upgrade to v4.19, it was reduced to the 2^17 = 128 KiB default. Increase it back up to 2^19 = 512 KiB so the entire boot up log can be captured and saved into the persistent logcat section of bugreports. Change-Id: Id3f6a03c8dda3c1a51ac08b208c4a9fe0886a7af

2021-03-03Enable CPUSETS to fix systraceTim Kryger
Android expects CPUSETS to be supported by the kernel and will attempt to mount its virtual filesystem at /dev/cpusets and then configure it. If the kernel doesn't support CPUSETS then Android ends up writing to the /dev tmpfs which means only files explicitly written are present which confuses systrace as it expects certain files to always exist in each cpusets subdirectory.
