2022-05-02fastboot: Fallback to "raw" partition type if fastboot hal isn't presentLuK1337
Fastboot format fails to wipe any partition that doesn't at least return "raw" partition type. Also both android.hardware.fastboot@1.0-impl.pixel and android.hardware.fastboot@1.1-impl-mock return FileSystemType::RAW so I assume this is fine. Change-Id: I5707bddb1ba32edb6359858853d7b1afbf138b9f

2019-11-10fastbootd: Disallow certain operations during snapshot updates.David Anderson
When a snapshot is applied or is merging, requests to erase or flash userdata, metadata, or misc must be protected. In addition, the set_active command must be restricted when a merge is in progress. In addition, introduce a "snapshot-update merge" command for assisting with erase requests when a merge is in progress. As in recovery, this will force a merge to complete. Bug: 139154945 Test: apply update fastboot erase userdata fastboot erase metadata fastboot erase misc fastboot set_active Change-Id: I152446464335c62c39ffb4cc6366be9de19eac30
2019-10-31fastboot: Implement helper commands for Virtual A/B.David Anderson
This introduces two new commands to the fastboot protocol: - getvar snapshot-update-status - Return "none", "snapshotted", or "merging" depending on the current status set by the boot control HAL. - snapshot-update [cancel] - Cancel any pending snapshot-based updates via the boot control HAL. After this, the HAL should return MergeStatus::CANCELLED and "update-merge-status" should be "none". If no argument is specified, the snapshot-update-status is returned via an INFO response. Bootloaders are expected to implement this in a manner consistent with the boot control HAL. Fastboot-based tooling should expect wipes of userdata to fail when update-merge-status returns "merging". Thus, the force flag now cancel any pending snapshots. Bug: 139154945 Test: fastboot getvar snapshot-update-status fastboot snapshot-update cancel fastboot snapshot-update Change-Id: Idc423fe7656b212e929e64eb0e6b85b453e0e8dc
2018-11-20fastbootd: Support two super partitions for retrofit devices.David Anderson
Retrofit devices will have two super partitions, spanning the A and B slots separately. By design an OTA will never cause "A" or "B" partitions to be assigned to the wrong super. However, the same is not true of fastbootd, where it is possible to flash the inactive slot. We do not want, for example, logical "system_a" flashing to super_b. When interacting with partitions, fastbootd now extracts the slot suffix from a GetSuperSlotSuffix() helper. On retrofit devices, if the partition name has a slot, that slot will override FastbootDevice::GetCurrentSlot. This forces partitions in the inactive slot to be assigned to the correct super. There are two consequences of this. First, partitions with no slot suffix will default to the current slot. That means it is possible to wind up with two "scratch" partitions, if "adb remount" is used on both the "A" and "B" slots. However, only the active slot's "scratch" will be visible to the user (either through adb or fastboot). Second, if one slot does not have dynamic partitions, flashing will default to fixed partitions. For example, if the A slot is logical and B is not, flashing "system_a" will be logical and "system_b" will be fixed. This works no matter which slot is active. We do not try to upgrade the inactive slot to dynamic partitions. Bug: 116802789 Test: fastboot set_active a fastboot flashall # dynamic partitions fastboot getvar is-logical:system_a # true fastboot getvar is-logical:system_b # false fastboot set_active b fastboot flashall --skip-secondary fastboot getvar is-logical:system_a # true fastboot getvar is-logical:system_b # true Booting both slots works.

2018-11-06fastboot: Query the name of the super partition.David Anderson
This patch adds a new variable, "super-partition-name", to query the name of the super partition (with a slot suffix if it has one). The fastboot flashing tool has been updated to query this variable. Since the super partition name can no longer be determined without fastbootd, the presence of super_empty.img is used to test for dynamic partition support rather than the presence of a super partition.

2018-08-31fastbootd: Implement getvar all.David Anderson
This implements getvar all by invoking each callback and writing an INFO status for each result.

2018-08-09fastbootd: Add support for flashing logical partitions.David Anderson
When flashing logical partitions, we read the "super" partition metadata corresponding to the current slot. We then temporarily create a device-mapper device for that partition, and immediately destroy the device after all operations are complete. We do not mount partitions ahead of time, or keep them mounted, because a fastboot operation may change the layout of the logical partition table (or change which slot is current).
