* do sdcard sideloading through the fuse filesystemDoug Zongker2014-07-101-1/+2
| | | | | | | | | Make a fuse filesystem that sits on top of the selected package file on the sdcard, so we can verify that the file contents don't change while being read and avoid copying the file to /tmp (that is, RAM) before verifying and installing it.

* refactor fuse sideloading codeDoug Zongker2014-07-101-0/+13
| | | | | | | | | Split the adb-specific portions (fetching a block from the adb host and closing the connections) out from the rest of the FUSE filesystem code, so that we can reuse the fuse stuff for installing off sdcards as well. Change-Id: I0ba385fd35999c5f5cad27842bc82024a264dd14

* | remove pixelflinger from recoveryDoug Zongker2014-03-111-1/+0
|/ | | | | | | | | | | | | | | | Recovery now draws directly to the framebuffer by rolling its own graphics code, rather than depending on libpixelflinger. The recovery UI is modified slightly to eliminate operations that are slow with the software implementation: when the text display / menu is turned on, it now appears on a black background instead of a dimmed version of the recovery icon. There's probably substantial room for optimization of the graphics operations. Bug: 12131110 Change-Id: Iab6520e0a7aaec39e2ce39377c10aef82ae0c595

* program to store unencrypted files in an encrypted filesystemDoug Zongker2014-01-161-0/+1
| | | | | | | | | | | | | | | uncrypt can read a file on an encrypted filesystem and rewrite it to the same blocks on the underlying (unencrypted) block device. This destroys the contents of the file as far as the encrypted filesystem is concerned, but allows the data to be read without the encryption key if you know which blocks of the raw device to access. uncrypt produces a "block map" file which lists the blocks that contain the file. For unencrypted filesystem, uncrypt will produce the block map without touching the data. Bug: 12188746 Change-Id: Ib7259b9e14dac8af406796b429d58378a00c7c63
* do verification and extraction on memory, not filesDoug Zongker2014-01-161-0/+1
| | | | | | | | | | | | | | | | Changes minzip and recovery's file signature verification to work on memory regions, rather than files. For packages which are regular files, install.cpp now mmap()s them into memory and then passes the mapped memory to the verifier and to the minzip library. Support for files which are raw block maps (which will be used when we have packages written to encrypted data partitions) is present but largely untested so far.

* | support "sideload over ADB" modeDoug Zongker2012-01-101-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rather than depending on the existence of some place to store a file that is accessible to users on an an unbootable device (eg, a physical sdcard, external USB drive, etc.), add support for sideloading packages sent to the device with adb. This change adds a "minimal adbd" which supports nothing but receiving a package over adb (with the "adb sideload" command) and storing it to a fixed filename in the /tmp ramdisk, from where it can be verified and sideloaded in the usual way. This should be leave available even on locked user-build devices. The user can select "apply package from ADB" from the recovery menu, which starts minimal-adb mode (shutting down any real adbd that may be running). Once minimal-adb has received a package it exits (restarting real adbd if appropriate) and then verification and installation of the received package proceeds.

Fix up the key handling so there is less crosstalk between the immediate keys and the queued keys (an increasing annoyance on button-limited devices).

* | refactor ui functions into a classDoug Zongker2011-10-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | Move all the functions in ui.c to be members of a ScreenRecoveryUI class, which is a subclass of an abstract RecoveryUI class. Recovery then creates a global singleton instance of this class and then invoke the methods to drive the UI. We use this to allow substitution of a different RecoveryUI implementation for devices with radically different form factors (eg, that don't have a screen).

* relocate applypatch; add type system and new functions to edifyDoug Zongker2010-02-181-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | - Move applypatch to this package (from build). - Add a rudimentary type system to edify: instead of just returning a char*, functions now return a Value*, which is a struct that can carry different types of value (currently just STRING and BLOB). Convert all functions to this new scheme. - Change the one-argument form of package_extract_file to return a Value of the new BLOB type. - Add read_file() to load a local file and return a blob, and sha1_check() to test a blob (or string) against a set of possible sha1s. read_file() uses the file-loading code from applypatch so it can read MTD partitions as well. This is the start of better integration between applypatch and the rest of edify. b/2361316 - VZW Issue PP628: Continuous reset to Droid logo: framework-res.apk update failed (CR LIBtt59130) Change-Id: Ibd038074749a4d515de1f115c498c6c589ee91e5
