applypatch() was initially designed for file-based OTA, operating on
individual files. It was later extended to allow patching eMMC targets
as a whole, in favor of block-based updates.
As we have deprecated file-based OTA since Oreo, part of the code in
applypatch() has become obsolete. This CL refactors the related
functions, by removing the obsolete logic and focusing on eMMC targets.
Since this CL substantially changes applypatch APIs, it adds new
functions to avoid unintentionally mixing them together. In particular,
it removes `applypatch()`, `applypatch_check()`, `applypatch_flash()`,
and adds `PatchPartition()`, `PatchPartitionCheck()`, `FlashPartition()`
and `CheckPartition()`. It also replaces the old Edify functions
`apply_patch()` and `apply_patch_check()` with `patch_partition()` and
`patch_partition_check()` respectively.
This CL requires matching changes to OTA generation script (in the same
topic).

They are doing exactly the same thing, except for the slightly different
error return value (1 vs -1).
int CacheSizeCheck(size_t bytes);
int MakeFreeSpaceOnCache(size_t bytes_needed);
This CL consolidates the two functions and uses bool as its return type.
// Checks whether /cache partition has at least 'bytes'-byte free space. Returns true immediately
// if so. Otherwise, it will try to free some space by removing older logs, checks again and
// returns the checking result.
bool CheckAndFreeSpaceOnCache(size_t bytes);

It used to return a Value blob to be consumed by sha1_check() (which has
been deprecated). Currently there's no other generic updater function
that works with BLOB Values. This CL changes read_file() to return a
string Value to make it more useful (e.g. allowing equality check).

The matching edify function has been removed from EdifyGenerator [1]. In
theory device-specific releasetools script may still use this function,
but it no longer looks useful. Because a) we should use range_sha1()
when asserting the SHA-1 hash of a block device; b) we should look into
the contents when asserting a text file.

This breaks the dependency on common.h (which belongs to
recovery/librecovery) from librecovery_ui. reboot() is now owned by
libotautil, which is expected to be a leaf node to be depended on.

now.

The AbortFn() used to overwrite the error message, hiding the real
failure reported in ErrorAbort(). And we will miss the failure in
the script patterns like 'blockimageupdate() || abort()'
We will ensure there's one line break at the end of ErrorAbort's
error message; and append to the existing error message when calling
abort().

Commit adeb41a8c0da3122a2907acb4aafd7ff9bce26af has switched the
argument for recovery. This CL handles the case for updater.

recovery (and f2fs 1.4.1 binary). Not sending a 0-sector argument to
f2fs 1.4.1 also works.

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.

Remove O_SYNC from mzExtractRecursive() and PackageExtractFileFn().
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.

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.

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)

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.

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.

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.

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.

Full OTAs currently fail if the build contains a directory containing
only symlinks, because nothing creates that directory. Change the

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.

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.
|
|
An extra parameter was added to the make_ext4fs() function, we these tools need
to be updated to match.

Separate files for retouch functionality are in minelf/*
ASLR for shared libraries is controlled by "-a" in ota_from_target_files.
Binary files are self-contained. Retouch logic can recover from crashes.

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.)

- 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.

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.

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.

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).
|
|
Handy for producing debugging OTA packages (eg, running sqlite3 or
whatever in recovery).
|
|
We were inadvertently skipping over the first filename in the list of
arguments.
|
|
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 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.
|
|
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".

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.

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).
