2021-03-30Allow /postinstall files to have custom contextsAlex Light
We were mounting /postinstall with a 'context=...' option. This forces all files within /postinstall to have a single selinux context, limiting the possible granularity of our policies. Here we change it to simply default to the 'postinstall_file' context for the 'system' partition but allow individual files to have their own custom contexts defined by /system/sepolicy. Other partitions retain the single 'postinstall_file' context. The sample_images were updated to manually add a selinux label for testing FS contexts.

2021-03-16Pass in source slot to ctor of dynamic controlKelvin Zhang
When DynamicPartitionControlAndroid is constructed, it initializes both source and target slot to -1. These values get updated during PreparePartitionsForUpdate call. And we only PreparePartitionsForUpdate() when applying an OTA or applocating space for an OTA(not when verifying OTA metadata). Which means if VerifyPayloadApplicable() is called before any call two other APIs, we could be using an "Uninitialiazed" dynamic partition control. To mitigate this problem, we pass in source_slot at ctor of DynamicPartitionControl, also make IsDynamicPartition() api take in a slot number to avoid reading uninitialized member fields. Bug: 181643302 Test: apply an OTA, abort, restart update_engine, verify a payload Change-Id: I9a8a0fe8a9aca48e91241e15bdec33a1c1228553
