* Replace _exit(-1) with _exit(EXIT_FAILURE).Tao Bao2017-02-031-1/+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
* Avoid to call UI functions in child processTianjie Xu2017-02-031-1/+5
| | | | | | | | | | | ui_print uses a mutex to protect the critical section. And a forked child process may intialize the mutex inappropriatly, which leads to a hanging child process. So we shall avoid to call the UI functions in child process. Bug: 34769056 Test: fake ota on fugu failed as expected due to updater format mismatch.

* Print with newline for ui_print.Tao Bao2017-01-221-5/+1
| | | | | | | | | | | | | | | | | | | Currently the ui_print command between the recovery and updater doesn't append newline. Updater has to send an extra "ui_print" command without any argument to get the line break. This looks unnecessary. And not all the callers (including the ones in bootable/recovery) are following this protocol when sending the ui_print command. This CL simplifies the protocol to always print with a newline for ui_print command. When updating from an old recovery with the new updater, all the ui_print'd strings would appear in one line as a side effect. But a) it would only affect the text-mode UI, which won't be shown to users; b) log files won't be affected. Bug: 32305035 Test: Apply an update with the new updater on top of an old and new recovery image respectively. Change-Id: I305a0ffc6f180daf60919cf99d24d1495d68749b

The "stage" and "reason" variables are now declared as global by dropping the static qualifier, because they may be used by vendor recovery libraries.

| * Use BoringSSL instead of mincrypt to speed up package verification.Elliott Hughes2016-04-141-8/+9
| | | | | | | | | | | | | | | | | | | | | | | | This changes the verification code in bootable/recovery to use BoringSSL instead of mincrypt. Cherry-pick of 452df6d99c81c4eeee3d2c7b2171901e8b7bc54a, with merge conflict resolution, extra logging in verifier.cpp, and an increase in the hash chunk size from 4KiB to 1MiB.

* Log update outputs in orderTao Bao2015-06-031-2/+2
| | | | | | | | | | | | | | Although stdout and stderr are both redirected to log file with no buffering, we are seeing some outputs are mixed in random order. This is because ui_print commands from the updater are passed to the recovery binary via a pipe, which may interleave with other outputs that go to stderr directly. In recovery, adding ui::PrintOnScreenOnly() function to handle ui_print command, which skips printing to stdout. Meanwhile, updater prints the contents to stderr in addition to piping them to recovery. Change-Id: Idda93ea940d2e23a0276bb8ead4aa70a3cb97700

* Rotate logs only when there are actual operationsTao Bao2015-04-081-0/+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).

* sideload without holding the whole package in RAMDoug Zongker2014-07-021-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* disable async reboot during package installationDoug Zongker2014-05-231-0/+7
| | | | | | | | | | The default recovery UI will reboot the device when the power key is pressed 7 times in a row, regardless of what recovery is doing. Disable this feature during package installation, to minimize the chance of corrupting the device due to a mid-install reboot. (Debug packages can explicitly request that the feature be reenabled.)

* do verification and extraction on memory, not filesDoug Zongker2014-01-161-7/+23
| | | | | | | | | | | | | | | | 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.

* Restore default umask after forking for update-binary.Alistair Strachan2013-11-181-0/+1
| | | | | | | | | | | | | | | | | | | | | | A system/core change made in Mar 26 2012 6ebf12f "init: Change umask of forked processes to 077" changed the default umask of services forked from init. Because recovery is forked from init, it has a umask of 077. Therefore when update-binary is forked from recovery, it too has a umask of 077. This umask is overly restrictive and can cause problems for scripts relying on minzip to extract binaries directly into the target filesystem. Any directories updated by minzip will have their permissions reset to r-x------ and created files will have similarly restrictive permissions. As it seems unlikely this security measure was intended to have this side effect on legacy sideloads that do not have chmods to repair the damage done by minzip, this change reverts the umask to 022 in the fork made for update-binary.

* recovery: install packages in a known mount environmentDoug Zongker2013-08-211-5/+10
| | | | | | | | | | | When installing a package, we should have /tmp and /cache mounted and nothing else. Ensure this is true by explicitly mounting them and unmounting everything else as the first step of every install. Also fix an error in the progress bar that crops up when you do multiple package installs in one instance of recovery. Change-Id: I4837ed707cb419ddd3d9f6188b6355ba1bcfe2b2
* recovery: move log output to stdoutDoug Zongker2013-07-091-0/+1

* add simple text to recovery UIDoug Zongker2012-08-231-1/+1
| | | | | | | | | | | | | | | - recovery takes a --locale argument, which will be passed by the main system - the locale is saved in cache, in case the --locale argument is missing (eg, when recovery is started from fastboot) - we include images that have prerendered text for many locales - we split the background states into four (installing update, erasing, no command, error) so that appropriate text can be shown.

| | | | | | | | | | | | - add the --just_exit option to make recovery exit normally without doing anything - make it possible to build updater extensions in C++ - add the clear_display command so that the updater binary can request recovery switch to the NONE background UI These are all used to support the notion of using OTA as a factory reflash mechanism.

* refactor ui functions into a classDoug Zongker2011-10-291-14/+20
| | | | | | | | | | | 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).
