* support don't-care maps when writing the system imageDoug Zongker2014-02-251-62/+172
| | | | | | | | | | | | | | Make package_extract_file() take an optional third argument which is the pathname (in the package zip) of a map of don't-care regions to skip over when writing the file. Modify syspatch() to take source and target don't-care maps and use them when patching the system partition. Add the wipe_block_device() function to do a discard of all data on the partition.

* do verification and extraction on memory, not filesDoug Zongker2014-01-161-4/+11
| | | | | | | | | | | | | | | | 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.

| * add the functions for multi-stage packages to updaterDoug Zongker2013-11-271-1/+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.

* updater: introduce and set_metadata and set_metadata_recursiveNick Kralevich2013-09-101-0/+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

* Update OTA installer to understand SELinux filesystem labelsNick Kralevich2013-07-191-5/+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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The bonus data option lets you give an additional blob of uncompressed data to be used when constructing a patch for chunk #1 of an image. The same blob must be available at patch time, and can be passed to the command-line applypatch tool (this feature is not accessible from edify scripts). This will be used to reduce the size of recovery-from-boot patches by storing parts of the recovery ramdisk (the UI images) on the system partition.

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

| | * remove updater from the user system imageDoug Zongker2009-06-261-1/+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.

| * 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).
