2017-04-13Verify the package compatibility with libvintf.Tao Bao1-0/+73
verify_package_compatibility() is added to parse the compatibility entry (compatibility.zip) in a given OTA package. If entry is present, the information is sent to libvintf to check the compatibility. This CL doesn't actually call libvintf, since the API there is not available yet. Bug: 36597505 Test: Doesn't break the install with existing packages (i.e. w/o the compatibility entry).

Log the maximum temperature as well as the start/end temperature of an update to last_install. Check the temperature at the end of each block_image_update(verify). To get the maximum temp, we iterate through /sys/class/thermal/thermal_zone*/temp and find the maximum value present.

2017-03-17Drop the dependency on 'ui' in verify_file().Tao Bao1-19/+21
verify_file() has a dependency on the global variable of 'ui' for posting the verification progress, which requires the users of libverifier to provide a UI instance. This CL adds an optional argument to verify_file() so that it can post the progress through the provided callback function. As a result, we can drop the MockUI class in verifier_test.cpp. Test: recovery_component_test passes. Test: verify_file() posts progress update when installing an OTA.

2017-02-03Avoid to call UI functions in child processTianjie Xu1-1/+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. Change-Id: I81bc942a796878fac19cf712512092c2b0d807c9
2017-01-22Print with newline for ui_print.Tao Bao1-5/+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

2015-06-03Log update outputs in orderTao Bao1-2/+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

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).

2014-07-02sideload without holding the whole package in RAMDoug Zongker1-4/+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
2014-05-23disable async reboot during package installationDoug Zongker1-0/+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.)

2014-01-16do verification and extraction on memory, not filesDoug Zongker1-7/+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.

2013-11-18Restore default umask after forking for update-binary.Alistair Strachan1-0/+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.

2013-08-21recovery: install packages in a known mount environmentDoug Zongker1-5/+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

2012-08-23add simple text to recovery UIDoug Zongker1-1/+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.

2011-10-31refactor ui functions into a classDoug Zongker1-14/+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).

2011-10-19allow recovery packages to wipe cacheDoug Zongker1-11/+12
updater now has a function "wipe_cache();" which causes recovery to wipe the cache partition after the successful installation of the package. Move log copying around a bit so logs and the last_install flag file are copied to cache after it's wiped. Bug: 5314244 Change-Id: Id35a9eb6dcd626c8f3a3a0076074f462ed3d44bd
2011-04-12save a last_install file with the result of the last package install attemptDoug Zongker1-2/+24
When installing a package, create /cache/recovery/last_install, which contains the filename of the package and a 1 or 0 for success or failure. Also, don't mount ext4 and vfat filesystems as read-only (on devices where /cache is ext4, we need it to be read-write). Change-Id: I0cf2a1921bbd65e06343aa74e2006577fac77c2c

Remove the wacky notion of "roots" and "root paths" (those things that look like "FOO:some/path" instead of just "/foo/some/path"). Let each device specify its own table of available partitions and how to mount them (needed for devices that use both MTD/yaffs2 and EMMC/ext4 partitions).

2010-09-15close update package before installing; allow remountDoug Zongker1-1/+3
Close the update package before invoking the binary, to allow the installer to unmount /cache if it wants to. Add a function to allow remounting of a mount as read-only. Change-Id: Idfcc96c3da66083295177f729263560be58034e4

2009-07-15remove amendDoug Zongker1-103/+2
Yank all the code to install OTA packages out of the recovery binary itself. Now packages are installed by a binary included in the package (run as a child of recovery), so we can make improvements in the installation process without waiting for a new release to use them.
2009-06-24improve updater progress barDoug Zongker1-1/+13
Let recovery accept set_progress commands to control progress over the 'current segment' of the bar. Add a set_progress() builtin to the updater binary.
2009-06-18let the "firmware" command take the file straight from the packageDoug Zongker1-22/+44
To do a firmware-install-on-reboot, the update binary tells recovery what file to install before rebooting. Let this file be specified as "PACKAGE:<foo>" to indicate taking the file out of the OTA package, avoiding an extra copy to /tmp. Bump the API version number to reflect this change.
2009-06-12fixes to edify and updater scriptDoug Zongker1-0/+10
A few more changes to edify: - fix write_raw_image(); my last change neglected to close the write context, so the written image was corrupt. - each expression tracks the span of the source code from which it was compiled, so that assert()'s error message can include the source of the expression that failed. - the 'cookie' argument to each Function is replaced with a State object, which contains the cookie, the source script (for use with the above spans), and the current error message (replacing the global variables that were used for this purpose). - in the recovery image, a new command "ui_print" can be sent back through the command pipe to cause text to appear on the screen. Add a new ui_print() function to print things from scripts. Rename existing "print" function to "stdout".
2009-06-12edify extensions for OTA package installation, part 2Doug Zongker1-1/+2
Adds more edify functions for OTAs: is_mounted getprop apply_patch apply_patch_check apply_patch_space write_raw_image write_firmware_image package_extract_file This allows us to install radios, hboots, boot images, and install incremental OTA packages. Fixes a couple of dumb bugs in edify itself: - we were doubling the size of the function table each time it was *not* full, rather than each time it was full - "no such function" errors weren't visible to the parser, so they didn't prevent execution of the script.
2009-06-12edify extensions for OTA package installation, part 1Doug Zongker1-1/+1
Adds the following edify functions: mount unmount format show_progress delete delete_recursive package_extract symlink set_perm set_perm_recursive This set is enough to extract and install the system part of a (full) OTA package. Adds the updater binary that extracts an edify script from the OTA package and then executes it. Minor changes to the edify core (adds a sleep() builtin for debugging, adds "." to the set of characters that can appear in an unquoted string).
2009-06-05allow OTA package to provide binary instead of scriptDoug Zongker1-1/+169
Allow installation of OTA packages which do not contain an update-script, but instead contain an update-binary.
2009-05-29don't say "install complete" when it really isn'tDoug Zongker1-1/+1
Change the recovery UI so that when there is a hboot or radio update pending (which the user most do a home+back reboot to actually install), the UI tells them so, instead of saying "Install from sdcard complete."
