2016-01-07updater: Add a function to check first blockTianjie Xu2-0/+58
Add and register a function to check if the device has been remounted since last update during incremental OTA. This function reads block 0 and executes before partition recovery for version >= 4.

2015-10-19Error correction: Use libfec in blockimg.cpp for recoverySami Tolvanen2-1/+78
Add block_image_recover function to rewrite corrupted blocks on the partition. This can be attempted if block_image_verify fails. Note that we cannot use libfec during block_image_update as it may overwrite blocks required for error correction. A separate recovery pass in case the image is corrupted is the only viable option.

2015-06-03Log update outputs in orderTao Bao1-0/+6
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

2015-04-17Don't remove existing explicitly stashed blocksSami Tolvanen1-10/+28
When automatically stashing overlapping blocks, should the stash file already exist due to an explicit stash command, it's not safe to remove the stash file after the command has completed. Note that it is safe to assume that the stash file will remain in place during the execution of the next command, so we don't have take other measures to preserve overlapping blocks. The stash file itself will be removed by a free command when it's no longer needed. Bug: 20297065 Change-Id: I8ff1a798b94086adff183c5aac03260eb947ae2c

2015-01-30Support resuming block based OTAsSami Tolvanen1-346/+1460
Add support for transfer list version 3, which allows us to verify the status of each command and resume an interrupted block based OTA update. Notes on the changes: - Move the previous BlockImageUpdateFn to a shorter and reusable PerformBlockImageUpdate, which can be used also in BlockImageVerifyFn for verification. - Split individual transfer list commands into separate functions with unified parameters for clarity, and use a hash table to locate them during execution. - Move common block reading and writing to ReadBlocks and WriteBlocks to reduce code duplication, and rename the readblock and writeblock to less confusing read_all and write_all. The coding style of the new functions follows the existing style in the updater/edify code.

The recovery image doesn't actually care... but if we are not explicit in this, the makefiles will ask for the 64bit binaries but the Android.mk for the binaries will supply the 32bit images (causing the build to fail).

2014-10-24unconditionally apply SELinux labels to symlinksNick Kralevich1-10/+9
At the end of the OTA script, we walk through /system, updating all the permissions on the filesystem, including the UID, GID, standard UNIX permissions, capabilities, and SELinux labels. In the case of a symbolic link, however, we want to skip most of those operations. The UID, GID, UNIX permissions, and capabilities don't meaningfully apply to symbolic links. However, that's not true with SELinux labels. The SELinux label on a symbolic link is important. We need to make sure the label on the symbolic link is always updated, even if none of the other attributes are updated. This change unconditionally updates the SELinux label on the symbolic link itself. lsetfilecon() is used, so that the link itself is updated, not what it's pointing to. In addition, drop the ENOTSUP special case. SELinux has been a requirement since Android 4.4. Running without filesystem extended attributes is no longer supported, and we shouldn't even try to handle non-SELinux updates anymore. (Note: this could be problematic if these scripts are ever used to produce OTA images for 4.2 devices) Bug: 18079773 Change-Id: I87f99a1c88fe02bb2914f1884cac23ce1b385f91

2014-09-26support for version 2 of block image diffsDoug Zongker1-45/+209
In version 2 of block image diffs, we support a new command to load data from the image and store it in the "stash table" and then subsequently use entries in the stash table to fill in missing bits of source data we're not allowed to read when doing move/bsdiff/imgdiff commands. This leads to smaller update packages because we can break cycles in the ordering of how pieces are updated by storing data away and using it later, rather than not using the data as input to the patch system at all. This comes at the cost of the RAM or scratch disk needed to store the data. The implementation is backwards compatible; it can still handle the existing version 1 of the transfer file format.

2013-11-27add the functions for multi-stage packages to updaterDoug Zongker1-1/+106
In order to support multi-stage recovery packages, we add the set_stage() and get_stage() functions, which store a short string somewhere it can be accessed across invocations of recovery. We also add reboot_now() which updater can invoke to immediately reboot the device, without doing normal recovery cleanup. (It can also choose whether to boot off the boot or recovery partition.) If the stage string is of the form "#/#", recovery's UI will be augmented with a simple indicator of what stage you're in, so it doesn't look like a reboot loop.

2013-09-10updater: introduce and set_metadata and set_metadata_recursiveNick Kralevich1-0/+274
Introduce two new updater functions: * set_metadata * set_metadata_recursive Long term, these functions are intended to be more flexible replacements for the following methods: * set_perm * set_perm_recursive Usage: set_metadata("filename", "key1", "value1", "key2", "value2", ...) set_metadata_recursive("dirname", "key1", "value1", "key2", "value2", ...) Description: set_metadata() and set_metadata_recursive() set the attributes on a file/directory according to the key/value pairs provided. Today, the following keys are supported: * uid * gid * mode (set_perm_extd only) * fmode (set_perm_extd_recursive only) * dmode (set_perm_extd_recursive only) * selabel * capabilities Unknown keys are logged as warnings, but are not fatal errors. Examples: * set_metadata("/system/bin/netcfg", "selabel", "u:object_r:system_file:s0"); This sets the SELinux label of /system/bin/netcfg to u:object_r:system_file:s0. No other changes occur. * set_metadata("/system/bin/netcfg", "uid", 0, "gid", 3003, "mode", 02750, "selabel", "u:object_r:system_file:s0", "capabilities", 0x0); This sets /system/bin/netcfg to uid=0, gid=3003, mode=02750, selinux label=u:object_r:system_file:s0, and clears the capabilities associated with the file. * set_metadata_recursive("/system", "uid", 0, "gid", 0, "fmode", 0644, "dmode", 0755, "selabel", "u:object_r:system_file:s0", "capabilities", 0x0); All files and directories under /system are set to uid=0, gid=0, and selinux label=u:object_r:system_file:s0. Directories are set to mode=0755. Files are set to mode=0644 and all capabilities are cleared. Bug: 10183961 Bug: 10186213 Bug: 8985290 Change-Id: Ifdcf186a7ed45265511dc493c4036e1ac5e3d0af

2013-07-19Update OTA installer to understand SELinux filesystem labelsNick Kralevich1-5/+24
Modify the OTA installer to understand SELinux filesystem labels. We do this by introducing new set_perm2 / set_perm2_recursive calls, which understand SELinux filesystem labels. These filesystem labels are applied at the same time that we apply the UID / GID / permission changes. For compatibility, we preserve the behavior of the existing set_perm / set_perm_recursive calls. If the destination kernel doesn't support security labels, don't fail. SELinux isn't enabled on all kernels. Bug: 8985290 Change-Id: I99800499f01784199e4918a82e3e2db1089cf25b

2010-09-15support for ext4/EMMC filesystems in updater binaryDoug Zongker2-25/+64
Make the mount and format functions take extra parameters describing the filesystem type and add support for mounting and formatting ext4 filesystems on EMMC. Change recovery to consistently use stdout for status messages instead of mixing stdout and stderr.
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
2010-08-14Changes to work with updated make_ext4fs tool that supports creating sparse images.Ken Sumrall1-1/+1
An extra parameter was added to the make_ext4fs() function, we these tools need to be updated to match. Change-Id: Id640a7f2b03153eb333b00337f0f991ff5332349

2010-07-02support for ext4/EMMC filesystems in updater binaryDoug Zongker2-25/+64
Make the mount and format functions take extra parameters describing the filesystem type and add support for mounting and formatting ext4 filesystems on EMMC. Change recovery to consistently use stdout for status messages instead of mixing stdout and stderr.
2010-02-23refactor applypatch and friendsDoug Zongker1-65/+107
Change the applypatch function to take meaningful arguments instead of argc and argv. Move all the parsing of arguments into main.c (for the standalone binary) and into install.c (for the updater function). applypatch() takes patches as Value objects, so we can pass in blobs extracted from the package without ever writing them to temp files. The patching code is changed to read the patch from memory instead of a file. A bunch of compiler warnings (mostly about signed vs unsigned types) are fixed. Support for the IMGDIFF1 format is dropped. (We've been generating IMGDIFF2 packages for some time now.) Change-Id: I217563c500012750f27110db821928a06211323f
2010-02-18relocate applypatch; add type system and new functions to edifyDoug Zongker2-52/+190
- Move applypatch to this package (from build). - Add a rudimentary type system to edify: instead of just returning a char*, functions now return a Value*, which is a struct that can carry different types of value (currently just STRING and BLOB). Convert all functions to this new scheme. - Change the one-argument form of package_extract_file to return a Value of the new BLOB type. - Add read_file() to load a local file and return a blob, and sha1_check() to test a blob (or string) against a set of possible sha1s. read_file() uses the file-loading code from applypatch so it can read MTD partitions as well. This is the start of better integration between applypatch and the rest of edify. b/2361316 - VZW Issue PP628: Continuous reset to Droid logo: framework-res.apk update failed (CR LIBtt59130) Change-Id: Ibd038074749a4d515de1f115c498c6c589ee91e5
2010-02-03bump updater API version to 3; deprecate firmware update commandDoug Zongker3-42/+7
Remove support for the HTC-specific "firmware" update command and the corresponding edify function write_firmware_update(). This functionality is now done by an edify extension library that lives in vendor/htc. Change-Id: I80858951ff10ed8dfff98aefb796bef009e05efb
2010-02-01add a one-argument version of package_extract_fileDoug Zongker1-24/+69
Add a version of package_extract_file that returns the file data as its return value (to be consumed by some other edify function that expects to receive a bunch of binary data as an argument). Lets us avoid having two copies of a big file in memory (extracting it into /tmp, which is a ramdisk, and then having something load it into memory) when doing things like radio updates.

2009-09-19delete files before symlinking; log error messagesDoug Zongker1-3/+21
The symlink() function should remove existing files before creating symlinks, so scripts are idempotent. Log messages when various system calls fail (but don't make the whole script fail).
2009-09-10add a run_program() function to edifyDoug Zongker1-0/+49
Handy for producing debugging OTA packages (eg, running sqlite3 or whatever in recovery).
2009-06-26remove updater from the user system imageDoug Zongker1-1/+6
updater (which is only needed in OTA packages) is getting included in /system/bin, where it just takes up (quite a bit of) space. Use the hack of including it only in eng builds so it's not there for user builds.
2009-06-25fix off-by-one error in set_perm()Doug Zongker1-1/+1
We were inadvertently skipping over the first filename in the list of arguments.
2009-06-24improve updater progress barDoug Zongker1-3/+21
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.
2009-06-22add device extension mechanism to updaterDoug Zongker2-1/+43
Allow devices (in BoardConfig.mk) to define additional static libraries to be linked in to updater, to make device-specific functions available in edify scripts. Modify the updater makefile to arrange for device libraries to register their edify functions.
2009-06-18add file_getprop() to updaterDoug Zongker1-11/+100
Add a function to read a property from a ".prop"-formatted file (key=value pairs, one per line, ignore # comment lines and blank lines). Move ErrorAbort to the core of edify; it's not specific to updater now that errors aren't stored in the app cookie.
2009-06-18let the "firmware" command take the file straight from the packageDoug Zongker1-3/+4
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 Zongker2-67/+124
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 Zongker3-7/+278
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 Zongker5-0/+555
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).
