* Remove ota_close(int) and ota_fclose(FILE*).Tao Bao2016-11-281-73/+69
| | | | | | | | | | | We should always use unique_fd or unique_file to hold the FD or FILE* pointer when opening via ota_(f)open functions. This CL avoids accidentally closing raw FDs or FILE* pointers that are managed by unique_fd/unique_file. Test: recovery_component_test passes. Change-Id: If58eb8b5c5da507563f85efd5d56276472a1c957
* updater: Refactor set_stage() and get_stage() functions.Tao Bao2016-11-182-68/+69
| | | | | | | | | | | Add read_bootloader_message_from() and write_bootloader_message_to() to allow specifying the BCB device (/misc). Also add testcases for set_stage() and get_stage(). Test: recovery_component_test passes. Test: Build a recovery image and apply a two-step OTA package. Change-Id: If5ab06a1aaaea168d2a9e5dd63c07c0a3190e4ae

* updater: Add "write_value()" function.Tao Bao2016-11-171-3/+31
| | | | | | | | | | | | | write_value(value, filename) writes 'value' to 'filename'. It can be used to tune device settings when applying an OTA package. For example, write_value("960000", "/sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq"). Bug: 32463933 Test: recovery_component_test passes. Test: Apply an OTA package that contains a call to write_value(), and check the result. Change-Id: Ib009ecb8a45a94353f10c59e2383fe1f49796e35
* updater: Fix the wrong return value for package_extract_file().Tao Bao2016-11-151-76/+69
| | | | | | | | | | | | | | | 'bool success = ExtractEntryToFile()' gives opposite result. Fix the issue and add testcases. Change the one-argument version of package_extract_file() to explicitly abort for non-existent zip entry. Note that this is NOT changing the behavior. Prior to this CL, it aborts from Evaluate() function, by giving a general cause code. Now it returns kPackageExtractFileFailure. BUg: 32903624 Test: recovery_component_test works.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently block_image_verify() stashes source blocks to /cache and in some case triggers I/O errors. To avoid this risk, We create a map from the hash value to the source blocks' range_set. When executing stash command in verify mode, source range is saved but block contents aren't stashed. And load_stash could get its value from either the stashed file from the previous update, or the contents on the source partition specified by the saved range.

These functions deal with extracting whole files from the update package onto a filesystem. If run on ext4 on a rotating disk, for example, the O_SYNC flag will cause serious performance problems and the extraction proecss can take over 30 minutes, with no obvious benefits. This API function already calls fsync(fd) after each file is extracted to ensure data and metadata is written to the underlying block device, so the O_SYNC calls should be superfluous and safely removable. This change does not affect the OTA patch paths or any modification of the bootloader partition or writes to other 'emmc' partitions.

However, we were using memset(3) to zero out the struct, which effectively assigned unique_fd(0) to fd. When it called fd.reset(), file descriptor 0 was unintentionally closed. When FD 0 was later reassigned via open(2), it led to lseek(2) errors: "Bad file descriptor". This CL switches to using braced-init (i.e. '= {}') instead, so that the default constructor unique_fd(-1) would be called.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

The coding style of the new functions follows the existing style in the updater/edify code.

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.

* / support for version 2 of block image diffsDoug Zongker2014-09-261-45/+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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

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

Fix up the key handling so there is less crosstalk between the immediate keys and the queued keys (an increasing annoyance on button-limited devices).

* allow recovery packages to wipe cacheDoug Zongker2011-10-191-0/+10
| | | | | | | | | | 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

* refactor applypatch and friendsDoug Zongker2010-02-231-65/+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
* relocate applypatch; add type system and new functions to edifyDoug Zongker2010-02-182-52/+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
* bump updater API version to 3; deprecate firmware update commandDoug Zongker2010-02-033-42/+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
* add a one-argument version of package_extract_fileDoug Zongker2010-02-011-24/+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.

* delete files before symlinking; log error messagesDoug Zongker2009-09-191-3/+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).
* add a run_program() function to edifyDoug Zongker2009-09-101-0/+49

| * improve updater progress barDoug Zongker2009-06-241-3/+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.
* | add device extension mechanism to updaterDoug Zongker2009-06-222-1/+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.
* add file_getprop() to updaterDoug Zongker2009-06-181-11/+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.
* let the "firmware" command take the file straight from the packageDoug Zongker2009-06-181-3/+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.
* fixes to edify and updater scriptDoug Zongker2009-06-122-67/+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".
* edify extensions for OTA package installation, part 2Doug Zongker2009-06-123-7/+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.
* edify extensions for OTA package installation, part 1Doug Zongker2009-06-125-0/+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).
