From 69ffa15338503376c2dad1e33d23ebb42fba60d1 Mon Sep 17 00:00:00 2001 From: Tianjie Xu Date: Wed, 1 Aug 2018 16:40:00 -0700 Subject: Add an updater function to compute hash tree The new command is part of the transfer.list and allows us to compute the hash tree on non-ab devices. The required arguments for the hash_tree computation are: hash_tree_ranges source_ranges hash_algorithm salt_hex root_hash Bug: 25170618 Test: unit tests pass; run simulator with compute_hash_tree Change-Id: I8ff0d582cc8adabb8a060db7845f38b35b28e62c --- updater/include/private/commands.h | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'updater/include') diff --git a/updater/include/private/commands.h b/updater/include/private/commands.h index 087d7cfbf..7f9dc79f4 100644 --- a/updater/include/private/commands.h +++ b/updater/include/private/commands.h @@ -213,6 +213,10 @@ class PatchInfo { // - Free the given stash data. // - Meaningful args: StashInfo // +// compute_hash_tree +// - Computes the hash_tree bytes and writes the result to the specified range on the +// block_device. +// // abort // - Abort the current update.
