* Log a copy of recovery log to kernel logsKelvin Zhang2022-04-201-5/+5
| | | | | | | | | | Currently, recovery logs are only saved to /tmp/recovery.log . That's bad, because /tmp/recovery.log would not be available after reboot. To help debugging recovery issues, log a copy to kernel log, which will be saved in pstore after device reboots. Bug: 228893064 Change-Id: I0f97b402726ecabe644f3ff5182f71bd16d0b111
* Add EthernetDevice to manage ethernet connection.Hongguang Chen2020-05-161-0/+5
| | | | | | | | | | | | | | | | | | | | The current fastbootd only supports USB protocol. But some Android TV devices are built without USB port. The fastbootd cannot be used on those ATV devices due to it. aosp/1295566 enables fastbootd over ethernet. This change adds an EthernetDevice to manage ethernet connection and set fastbootd protcol property fastbootd.protocol to enable fastbootd over ethernet in recovery mode. It uses IPv6 link-local address to not expose the devices out of the network segment. The devices who want to use this EthernetDevice should add “TARGET_RECOVERY_UI_LIB := librecovery_ui_ethernet” into BoardConfig.mk. BUG: 152544169 Test: Enter and exit fastboot mode and check eth0 IPv6 link-local address on screen UI. Change-Id: I73fe44be3790bdba5a6059fbba3f7264b21eed99
* Start adbd in user mode if bootloader is unlockedTianjie Xu2019-10-301-1/+7
| | | | | | | | | | | | | | | During automatic tests, we sometimes want to reboot the device out of the rescue party remotely. And per http://go/recovery-adb-access, one option is to start adbd in user build if the device has an unlocked bootloader. This should not add more surface of attack. Because verified boot is off with the unlocked bootloader, and the user can always flash a custom recovery image that always starts adbd. Bug: 141247819 Test: check adbd doesn't start in user build, unlock bootloader, and check adbd starts. Change-Id: I851746245f862cb4dfb01e6c3ad035f2c9f9ccec
* otautil: Factor out the utils that're private to recovery.Tao Bao2019-10-021-2/+2
| | | | | | | | | | | A number of utility functions are intended for serving recovery's own use. Exposing them via libotautil (which is a static lib) would pass the dependencies onto libotautil's users (e.g. recovery image, updater, host simulator, device-specific recovery UI/updater extensions etc). This CL finds a new home for the utils that are private to recovery. Test: mmma bootable/recovery Change-Id: I575e97ad099b85fe1c1c8c7c9458a5a43d4e11e1
* recovery: Don't report unrecognized option in recovery_main.Tao Bao2019-09-191-0/+7
| | | | | | | | | | | | | | | | | | recovery_main is only interested in a subset of options. Suppress the warning for unrecognized options (which are likely intended for recovery). Fixes: 141239600 Test: On Pixel 3a, write `--security` flag into /misc and reboot recovery. Check that recovery_main no longer reports "unrecognized option" warning. # echo "recovery\n--security\n" | \ dd of=/dev/block/by-name/misc conv=notrunc bs=1 seek=64 # killall -9 recovery # cat /tmp/recovery.log Test: Write `--show_text=foo` instead, and check that recovery reports "option `--show_text' doesn't allow an argument".

* Remove common.hTianjie Xu2019-08-151-4/+15
| | | | | | | | | | | Additionally kill the global variable: reason, stage; move them to a separate BootState class instead. Vendor specific recovery code will need to call getters from Device() class to access these variables. Bug: 137705917 Test: unit tests pass, boot sailfish into recovery, code search and no code includes common.h in vendor specific recovery. Change-Id: Ia50a5ea951212c25548562f29cc9cf78505b5e34
* Clean up some global variables in common.hTianjie Xu2019-07-241-13/+11

* Parse BCB command to enter rescue mode.Tao Bao2019-04-251-4/+28
| | | | | | | | | | | | | | | | | bootloader will set `boot-rescue` in BCB command field to indicate booting into rescue mode. This CL adds the matching parsing code. This CL changes the on-screen UI to display the default image while waiting for each sideload / rescue command. It also changes the minadbd reboot handlers to use REBOOT_ instead of the previous ENTER_ actions. This ensures a reboot going through bootloader, which may load a newly installed bootloader/recovery. Bug: 128505466 Test: Boot into rescue mode. Run `adb rescue getprop` and `adb rescue install`. Check the UI. Then run `adb reboot rescue`. Change-Id: I5b7de9dfd898ed8e14bea0d4ad7385a9bae26e94

* Fall back to en-US if localized bitmap is missing for a localexunchang2019-04-221-1/+0
| | | | | | | | | | | We used to show the image for the last locale or an empty image, if the localized image is missing for a specific locale. As the default english one is more meaningful to users, we should just error out and fall back to use the default locale when the image loading fails.

* Move load & restore logs to logging.cppxunchang2019-04-161-1/+1
| | | | | | | | | | We perform these steps to perserve the recovery logs when wiping /cache partition. Move them to logging.cpp to keep the actually EraseVolume function concise. Bug: 130166585 Test: unit tests pass, mount cache and check last log after cache Change-Id: Idc52833817a446f3a0148a3dd2112f911c9ef48d
* Move wipe cache|data to libinstallxunchang2019-04-151-1/+4
| | | | | | | | | | | | | | | Therefore, libinstall becomes the sole owner to handle the request from minadbd service. The change also includes 1. move logging.cpp out of librecovery 2. drop the dependency on common.h 3. now it's more sensible to move the wipe_cache as part of install_package. move the wipe_cache to the end of the function.

* Add socket communication between recovery and minadbdxunchang2019-04-111-11/+0
| | | | | | | | | | | | | 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.

* Add a logo to the fastbootd screen.David Anderson2019-02-121-0/+2
| | | | | | | | | | | | | fastbootd looks too much like recovery, even if you're carefully reading the menu. It's not obvious the device is in a flashing mode, and it's too tempting to reboot or unplug the device in this state. As a first step, this patch adds a big red "fastbootd" logo so it's less obviously in recovery mode. Bug: 120429730 Test: manual test Change-Id: I73359f1fdfdc0b1694993f760fe7f35c5713b24e

* | recovery: Fix mounting /system with dynamic partitions.David Anderson2018-10-301-2/+7
|/ | | | | | | | | | | | | | | When using dynamic partitions, the blk_device field in fstab_rec must be translated to a /dev/block/dm-N node with fs_mgr_update_logical_partition. However, init will not have created these nodes to begin with since CreateLogicalPartitions is not called in recovery. This patch addresses both issues. Note that flashing system through fastbootd will not work while /system is mounted. Bug: 118634720 Test: manual test Change-Id: I06c83309d09eab6b65245b1ed10c51d05398f23e

* recovery: Add "boot-fastboot" command to BCB.David Anderson2018-08-221-1/+12
| | | | | | | | | | | This change adds a new "boot-fastboot" command in order to boot into fastboot without overwriting recovery tasks. This also allows bootloaders to boot directly into userspace fastboot from the bootloader menu, or via bootloader fastboot.

* Dynamically load device-specific recovery UI lib.Tao Bao2018-08-061-1/+27
| | | | | | | | | | | | | | | | | | | | | We used to statically link the device-specific recovery UI extension (`TARGET_RECOVERY_UI_LIB`) into `recovery`. Such a logic can't be easily migrated to Soong, as modules specified by `TARGET_RECOVERY_UI_LIB` may not be built with Soong. Instead of porting all the device-specific codes over, this CL builds and installs the UI lib as a shared library with Android.mk. `recovery` dlopen(3)'s and dlsym(3)'s `make_device` to invoke the device-specific UI lib on start. Note that in order to make dlopen(3) actually working, we have to switch `recovery` to be dynamically linked (we will make the move later anyway). Bug: 110380063 Test: Build and boot into marlin recovery image. Check that device-specific recovery UI is successfully loaded. Change-Id: Ia9861c7559a95f3f50676534540c0cb87cae4574
* Fix the arguments passed to getopt_long(3).Tao Bao2018-07-171-5/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | The getopt_long(3) implementation in Android (upstream freebsd) expects a null-terminated array while parsing long options with required args. if (long_options[match].has_arg == required_argument) { optarg = nargv[optind++]; } ... if (long_options[match].has_arg == required_argument && optarg == NULL) { return (BADARG); } This seems to make sense in practice, as getopt(3) takes the first two arguments of argc and argv that are "as passed to the main() function on program invocation", and both of C and C++ spec say "the value of argv[argc] shall be 0". Prior to the CL, we may run into undefined behavior on malformed input command line (e.g. missing arg for an option that requires one). This CL fixes the issue by always appending a nullptr to the argument list (but without counting that into argc). Test: Build and boot into recovery with commands.
