* sideload without holding the whole package in RAMDoug Zongker2014-07-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement a new method of sideloading over ADB that does not require the entire package to be held in RAM (useful for low-RAM devices and devices using block OTA where we'd rather have more RAM available for binary patching). We communicate with the host using a new adb service called "sideload-host", which makes the host act as a server, sending us different parts of the package file on request. We create a FUSE filesystem that creates a virtual file "/sideload/package.zip" that is backed by the ADB connection -- users see a normal file, but when they read from the file we're actually fetching the data from the adb host. This file is then passed to the verification and installation systems like any other. To prevent a malicious adb host implementation from serving different data to the verification and installation phases of sideloading, the FUSE filesystem verifies that the contents of the file don't change between reads -- every time we fetch a block from the host we compare its hash to the previous hash for that block (if it was read before) and cause the read to fail if it changes. One necessary change is that the minadbd started by recovery in sideload mode no longer drops its root privileges (they're needed to mount the FUSE filesystem). We rely on SELinux enforcement to restrict the set of things that can be accessed. Change-Id: Ida7dbd3b04c1d4e27a2779d88c1da0c7c81fb114
* add simple text to recovery UIDoug Zongker2012-08-231-1/+1
| | | | | | | | | | | | | | | - recovery takes a --locale argument, which will be passed by the main system - the locale is saved in cache, in case the --locale argument is missing (eg, when recovery is started from fastboot) - we include images that have prerendered text for many locales - we split the background states into four (installing update, erasing, no command, error) so that appropriate text can be shown.

* allow recovery packages to wipe cacheDoug Zongker2011-10-191-1/+5
| | | | | | | | | | updater now has a function "wipe_cache();" which causes recovery to wipe the cache partition after the successful installation of the package. Move log copying around a bit so logs and the last_install flag file are copied to cache after it's wiped. Bug: 5314244 Change-Id: Id35a9eb6dcd626c8f3a3a0076074f462ed3d44bd
