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

2014-05-23disable async reboot during package installationDoug Zongker1-0/+11
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.)

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.

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
2013-09-09Revert "Update OTA installer to understand SELinux filesystem labels"Nick Kralevich1-24/+5

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

2012-08-21add bonus data feature to imgdiff/imgpatch/applypatchDoug Zongker1-1/+1
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. Change-Id: Iac1959cdf7f5e4582f8d434e83456e483b64c02c
2012-08-07fix the symlink() command to create directories if neededDoug Zongker1-3/+29
Full OTAs currently fail if the build contains a directory containing only symlinks, because nothing creates that directory. Change the symlink() command to create any ancestor directories that don't exist. They're created as owner root perms 0700 because we assume that in practice subsequent set_perm_recursive() calls will fix up their ownership and permissions.

2012-02-28remove retouching code from updaterDoug Zongker1-118/+0
Removes the retouch_binaries and undo_retouch_binaries from updater; newly generated OTA packages should not call them any more. Note that applypatch retains the ability to unretouch a file as it reads it. This will be needed as long as we want to support OTAs from devices that were installed with retouching.

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 Zongker1-52/+184
- 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

2010-02-01add 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.

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.
2009-06-12fixes to edify and updater scriptDoug Zongker1-62/+104
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 Zongker1-3/+272
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 Zongker1-0/+370
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).
