* minadbd: Support `adb reboot` under sideload/rescue modes.Tao Bao2019-04-243-8/+54
| | | | | | | | | | | | Bug: 128415917 Test: Run the following commands under sideload and rescue modes respectively. $ adb reboot $ adb reboot bootloader $ adb reboot recovery $ adb reboot rescue $ adb reboot invalid Change-Id: I84daf63e3360b7b4a0af5e055149a4f54e10ba90
* Add test for minadbdxunchang2019-04-234-1/+226
| | | | | | | | | | | Ass some unit tests to check if the minadbd service exit correctly in the failure case. Also start the fuse and verify the socket communication between minadbd with adb host, and minadbd with recovery. Bug: 131037235 Test: run unit tests repeatedly, injects some errors and test fails without dangling process. Change-Id: I2f073b701b25d7f1aafc59868a7a91a8cbefaf49

| | | | | | | | | | Bug: 128415917 Test: Enter rescue mode on taimen. Send the following commands: `adb rescue getprop ro.build.fingerprint` `adb rescue getprop ro.build.date.utc` `adb rescue install /path/to/package.zip` Test: Sideload on taimen w/ `adb sideload /path/to/package.zip`.

* Add socket communication between recovery and minadbdxunchang2019-04-115-25/+187
| | | | | | | | | | | | | This cl adds a socket pair to support the communication between recovery and minadbd. Therefore, minadbd will be able to issue multiple commands to recovery and get back the status of each command. This cl also switches the adb sideload from the recovery menu to use this protocol; and moves minadbd to a separate binary.

| | | | | | | | | It's no longer needed with the newly added FuseDataProvider class. Also cleans up the parameters for run_fuse_sideload. Bug: 127071893 Test: unit tests pass, run a sideload Change-Id: I1ccd6798d187cfc6ac9f559ffb3f3edf08dad55c
* Create a FuseDataProvider base classxunchang2019-03-195-39/+45
| | | | | | | | | | | | The fuse data provider for adb/sdcard shares common code and structures. This cl creates a FuseDataProvider base class and provides implementations for adb and sdcard. In the follow cls, we can kill the provider_vtab struct; and also add another implementation to parse a block map file and provides data. Test: unit tests pass, sideload a package, apply a package from sdcard Change-Id: If8311666a52a2e3c0fbae0ee9688fa6d01e4ad09
* minadbd: daemon_service_to_fd takes std::string_view.Tao Bao2019-01-022-7/+9
| | | | | | | | | | | | The caller of daemon_service_to_fd() in core adb has switched to std::string_view in [1]. The mismatch breaks the sideload service, as it picks up the wrong daemon_service_to_fd() when serving sideload.

* Allow OTA package size larger than 2GiB(2147483647 bytes) on sideload.katao2018-09-271-10/+11
| | | | | | | | | | | | | | At present, multiple partitions such as vendor have been added, which reduces the coupling between mobile phone manufacturers and Android systems. However, it may increase the generated package size substantially (e.g. from ~200MB to ~800MB). Causes the package size to exceed the int limit (2147483647 bytes). Change the int length parameters to long. Bug: http://b/112003354 Test: adb sideload ota.zip (ota.zip bigger than 2147483647 bytes) Change-Id: Ifb656431f7b961ac0e91754107578dc8b89ff14e Signed-off-by: katao <katao@xiaomi.com>
* Reland "Build and use minadbd as a shared library."Tao Bao2018-08-131-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | This relands the previously reverted CL in commit c70446ce7b4db79f296833b16ce38eb8a01d83df ("Build and use minadbd as a shared library."). `recovery` has been built with Soong, so the previous concern (unintentionally installing `libminadbd_services.so` to normal system image) no longer holds. Note that `reocvery` can't use `libminadbd_services.a`, as functions like `daemon_service_to_fd()` (needed by `libadbd.so`) won't be linked into `recovery`. This CL moves the dependency of `libminadbd_services` from `librecovery` into `recovery`, as only the latter actually relies on it (via `recovery_main.cpp`). Note that we no longer need to list the transitive dependency on `libadbd` or `libasyncio`. Bug: 112494634 Test: `mmma -j bootable/recovery` Test: Build and boot into recovery with aosp_taimen-userdebug. Verify that sideloading keeps working.

* Revert "Build and use minadbd as a shared library."Tao Bao2018-08-081-9/+7
| | | | | | | | | | | | | | | | | | | This reverts commit 4fd4f89591fe826cf26167bccaeb2802f14fbdc8. The reverted CL has a side effect that unintentionally installs a copy of libminadbd_services.so to the system image. This breaks the check with `build/soong/build_test.bash --dist` which detects and prevents vendor modules from installing files to the system image. Prior to fully converting `recovery` to be built with Soong, we have to statically link recovery-specific modules into `recovery`. Bug: 110380063 Test: `m -j bootimage` with aosp_marlin-userdebug Test: Run minadbd_test on marlin. Test: Boot into recovery and verify that sideloading still works.

* Build and use minadbd as a shared library.Tao Bao2018-08-071-7/+9
| | | | | | | | | | | | | | | | | The former `minadbd` module is now built as a shared library (`libminadbd_services.so`) that serves sideloading under recovery, with a dynamic dependency on `libadbd.so`. This allows sharing and reusing libadbd code on device (both of `adbd` and `recovery` now uses `libadbd.so`). As a result, it reduces the size of `recovery` binary from 1407360-byte to (1272880 + 33032)-byte (aosp_marlin-userdebug). Bug: 78793464 Test: `m -j bootimage` with aosp_marlin-userdebug Test: Run minadbd_test on marlin. Test: Boot into recovery and verify that sideloading still works.

* minadbd: avoid overrriding services_to_fd.Josh Gao2018-07-271-22/+8
| | | | | | | | | | | | Previously, we were relying on linker ordering pulling in minadbd's copy of services_to_fd instead of libadbd's, which breaks when we switch to dynamically linking. Separate out libadbd's services into a separate function that's in a file that isn't built into libadbd, so that we can provide our own here.

| * Switch to bionic gtest in bootable/recoveryTianjie Xu2017-11-031-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We encountered segfaults in Imgdiff host tests due to the failure to reset states of getopt. The problem can be solved by switching to use bionic's gtest where a new process is forked for each test. Also modify the recovery_component_test to make sure it runs in parallel. Changes include: 1. Merge the writes to misc partition into one single test. 2. Change the hard coded location "/cache/saved.file" into a configurable variable.

* | adbd: Support for new f_fs descriptor formatBadhri Jagan Sridharan2015-01-261-54/+107
|/ | | | | | | | | | | | | | | | | | | | | The patch "[RFC] usb: gadget: f_fs: Add flags to descriptors block" marks the current usb_functionfs_descs_head format deprecated and introduces support for sending SuperSpeed descriptors. This CL makes adbd to send Descriptors in the new format. Adbd would fall back to the old format, if kernel is not able to recognize the new format. This is done to prevent adbd from breaking in the older versions of the kernel.

* | sideload without holding the whole package in RAMDoug Zongker2014-07-026-48/+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

* support "sideload over ADB" modeDoug Zongker2012-01-1016-0/+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.
