2014-11-07Fix up old libminui to compileEthan Yonker1-1/+1
Implement some needed updates to libminui to make it compile for healthd. Note that res_create_multi_display_surface is not fully implemented so healthd may still have issues with displaying some graphics. Will update later when we are able to test these changes.

2014-10-07ADB sideload command not workDa Zhou3-11/+358
In kernel(3.10) USB ADB gadget driver is removed. Using Functionfs for USB adb gadget. Android recovery uses a stripped down version of adb command for sideload only. It's missing the ffs function support, so add the ffs support to allow sideload command to work b/12608946 Change-Id: I4ad024723dfc5bdb544548391f99637c390b171e Signed-off-by: Pierre Couillaud <pierre@broadcom.com>
2014-07-10refactor fuse sideloading codeDoug Zongker6-522/+76
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 Zongker6-48/+557
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

2014-02-06recovery: fix building with pointer-to-int errors turned onColin Cross1-2/+2
Use intptr_t/uintptr_t to cast between pointer and int to allow building with -Werror=pointer-to-int-cast and Werror=int-to-pointer-cast turned on. Cast to char* instead of unsigned int for pointer arithmetic. Change-Id: Ia862306fdcca53866b330e8cf726f3d62f2248a0

2013-01-09exit instead of return if sideload file creation failsEthan Yonker1-1/+1
A return here leaves adb sideload in a permanent loop. An exit is more appropriate for this error. Change-Id: I80fb8abae4f6378833aa75f9eaf7ec1acd44b274 Signed-off-by: Ethan Yonker <ethanayonker@gmail.com>

2012-03-20run minadbd as shell user, remove unused codeDoug Zongker8-1171/+37
Make minadbd drop its root privileges after initializing. We need to make the /tmp directory writable by the shell group so that it can drop the sideloaded file there.

2012-01-18support "sideload over ADB" modeDoug Zongker16-0/+5529
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.
