2021-04-21android_system_image that generates linker.config.pbJiyong Park
android_system_image module type is a specialization of the android_filesystem module type. Currently, it adds a build rule for creating linker.config.pb from the information about all the other files in the filesystem and includes linker.config.pb to the filesystem as well. To do so, the filesystem module now provides a function pointer which subtype modules like android_system_image can implement to pass extra files that they want to package in the filesystem. In addition, the linkerconfig package is revised to make it possible to build linker.config.pb file outside of the package. Bug: 185391776 Test: m microdroid and inspect etc/linker.config.pb in it.

2021-03-17Fix PackagingBase.CopyDepsToZipJooyung Han
CopyDepsToZip() zips direct dependencies with tags implementing PackagingItem interface. Previously, it relied on InstallNeededDependencyTag which has a different meaning. - InstallNeededDependencyTag tells whether a dependency is required to be installed together. - PackagingItem tells whether a dependency (of PackagingBase) is required to be packaged. With the separation of InstallNeededDependencyTag and PackagingItem, PackagingBase module can distinguish cases which were not available before.(I = InstallNeededDependencyTag, P = PackagingItem) a (PackagingBase module) | |`--(I)--> b | |`--(P)--> c --(I)--> d | `--(I/P)--> e a's CopyDepsToZip(): [c, d, e] Test: m nothing (packaging_test) Change-Id: I71fce29b19b0f00dc394981bcf4240e9c1041c7a
2021-03-16Add vbmeta module typeJiyong Park
The module type is to create vbmeta image out of other partitions. Bug: 180676957 Test: m microdroid_vbmeta microdroid_vbmeta_system Inspect the built image using `avbtool info_image --image <image>` Change-Id: Iac92e9ab1640dcd488af69842e09850a91262bf1
2021-03-16bootimg signs image using verity_utilsJiyong Park
Previously, bootimg signed the image using avbtool. This didn't work because avbtool always requires that the partition size is given via '--partition_size' parameter. The partition size is hard to estimate especially when the image is not for a real physical partition, but for a logical partition in a composite image. With this change, the signing of bootimg is done by verity_utils.py which internally uses avbtool. The python script is capable of calculating the minimum required partition size when the partition size is not given. In addition, this change adds 'partition_name' property to the `android_filesystem` module type so that we can customize the partition name field in the vbmeta descriptor.

2020-12-01Clients of PackagingBase can customize dependency tag to useJiyong Park
Previously, the dep tag used by PackagingBase was fixed, which prevented some of its clients (e.g. cvd-host-package) from opting in to android.InstallAlwaysNeededDependencyTag. Now, PackagingBase.AddDeps accepts the dependency tag to use. Also, dependencies toward rust dylib, rlib, and proc_macro are configured to return true on InstallDepNeeded. This is required to install shared_lib dependencies of the rust modules when they are depended on by a rust binary. Exempt-From-Owner-Approval: a trivial change after +2 from the owner. This has to land ASAP as many users are affected by acloud being unavailable. Bug: N/A Test: m Test: acloud create --local-instance --local-image Change-Id: If22aee7c6f314fcb03b9d4fe6901a2557f1e899c
2020-11-19add android_filesystemJiyong Park
android_filesystem is a module type that can be used to create filesystem images out of binaries built for Android. Its initial use will be for creating an Android-like OS image to run on virtual machines, but the use is not limited to it. The module type currently lacks a lot of features like the support for other filesystem types, and the ability to do something like signing the image using avbtool, etc. Those will be added in follow-up CLs as we have actual demands. Bug: 172414391 Test: m Change-Id: I4b779d4586e04d9a960688e73b711166708558ab
