2017-05-11Don't write to /sys/class/android_usb/android0/enable with configfs.Tao Bao1-7/+16
USB configfs doesn't use /s/c/a/a/enable. Trying to set that gives confusing message on screen when sideloading. Bug: 37713851 Test: adb sideload on device using with configfs. Test: adb sideload on marlin. Change-Id: Ifa55f90c2a5fe6bf9e7cee95882de9f6de686d73
2017-05-01adb_install: Stop passing RecoveryUI as a parameter.Tao Bao1-96/+93
It's already a global declared in common.h which is included by adb_install.cpp. Remove '#include "minadbd/fuse_adb_provider.h"' that's not needed by adb_install.cpp (minadbd takes care of that). Test: mmma bootable/recovery Change-Id: I6d08b7abc706b4b05de2ef46a57ced2204ad297e
2017-02-03Replace _exit(-1) with _exit(EXIT_FAILURE).Tao Bao1-1/+1
-1 is not a valid exit status. Also replace a few exit(1) with exit(EXIT_FAILURE). Test: mmma bootable/recovery Change-Id: I4596c8328b770bf95acccc06a4401bd5cabd4bfd

2016-05-20Allow recovery to return error codesTianjie Xu1-1/+1
Write error code, cause code, and retry count into last_install. So we can have more information about the reason of a failed OTA. Example of new last_install: @/cache/recovery/block.map package name 0 install result retry: 1 retry count (new) error: 30 error code (new) cause: 12 error cause (new) Details in: go/android-ota-errorcode Bug: 28471955 Change-Id: I00e7153c821e7355c1be81a86c7f228108f3dc37

2015-04-09Enable printf format argument checking.Elliott Hughes1-1/+1
The original attempt missed the fact that Print is a member function, so the first argument is the implicit 'this'. Change-Id: I963b668c5432804c767f0a2e3ef7dea5978a1218
2015-04-08Rotate logs only when there are actual operationsTao Bao1-0/+2
Currently it rotates the log files every time it boots into the recovery mode. We lose useful logs after ten times. This CL changes the rotation condition so that it will rotate only if it performs some actual operations that modify the flash (installs, wipes, sideloads and etc).

2015-02-10recovery: Properly detect userdebug or eng buildsElliott Hughes1-3/+1
The recovery system behaves a little bit differently on userdebug or eng builds by presenting error reports to the user in the ui. This is controlled by checking the build fingerprint for the string :userdebug/ or :eng/. But with AOSP version numbers most AOSP builds blows the 92 char limit of ro.build.fingerprint and therefore the property is not set, so this condition will always be evaluated to false, for most builds. Instead of depending on the flaky ro.build.fingerprint this change uses ro.debuggable. Change-Id: I74bc00c655ac596aaf4b488ecea58f0a8de9c26b
2014-07-10refactor fuse sideloading codeDoug Zongker1-5/+6
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
2014-07-02sideload without holding the whole package in RAMDoug Zongker1-16/+51
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
2012-01-18support "sideload over ADB" modeDoug Zongker1-0/+110
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. always initialize usb product, vendor, etc. for adb in recovery Set these values even on non-debuggable builds, so that the mini-adb now in recovery can work.
